Which is better for teachers: the iPad or the iPad Pro?
August 7, 2021 adminEducationdiscovery education login, education galaxy, pa educator, tads educate
Teachers who want to spend less time teaching and more time doing more of the exciting things they love are going to have to find a new tablet, and that's why we've put together a new list of top 10 educational devices to make teaching more enjoyable.
The iPad Pro, the iPad Mini, and the iPad Air all come in a range of sizes, and while the iPad Pros come in smaller than the smaller models, the smaller iPad Air has an additional 12-inch screen and is also a much more affordable device, costing $499.99.
It is not the only iPad device with an additional screen size however.
The iPad mini is a slightly smaller tablet, with a smaller 9.7-inch display, and also comes with a $129.99 price tag.
The latest generation of the iPad mini, the 9.3-inch iPad Pro with Retina display, is priced at $799.99 with the iPad 8G.
This iPad Pro is the first iPad to come with the Apple Pencil accessory, and is available for $129 on Apple's website.
The iPad Air is the iPad with Retinas display, which also offers a larger screen than the iPad 9.5-inch model, but offers a higher price tag, $799 on Apple.com.
If you need to work from home, the Apple TV is a much cheaper alternative for the $249 model.
The Apple TV 4K has a larger 4K display, but is also more expensive at $149.99 on Apple, and costs $249 on Amazon.com for the 12-core Apple A8 processor and 4GB of RAM.
Apple's iPad Mini is the same as the previous generation of iPad, but with an added 16GB of storage and is now available in an 18-inch configuration.
The mini is priced for $499 on Apple and is sold on Amazon for $229.99 in the US.
The Mini's screen size is also significantly larger, with an 18.8-inch version available at $649.99 for $799 in the USA.
Finally, the new iPad Pro features a 10.1-inch, Super Retina screen with an 8.9-inch full HD display, as well as a more powerful Core i5 processor and 256GB of onboard storage.
The processor is a 7th generation chip, with 3.3GHz dual-core and 2.6GHz quad-core processors.
It also features a 4K video output with HDR and 4K UHD, making it the first tablet to feature 4K Ultra HD video.
The new iPad Air features a 12- and 16-inch Full HD displays, as seen in the iPad 10.5.
It comes with 64GB of internal storage, as opposed to the 16GB that the mini version offers.
The 12- or 16-core model of the Air also comes in a 13-inch variant for $599.99, while the larger iPad Air and the 10.9 or 11.7 models come in 16- and 18-core configurations.
The Air comes with two cameras, a microphone, an accelerometer, and a magnetometer, but there are no other accessories.
The new iPad has an improved camera sensor, including new sensor pixels, which allow it to focus at higher frequencies, and new camera-to-camera integration.
It has a 12MP rear camera with LED flash, a f/2.2 aperture lens, and an optical image stabilization technology that allows the image to be stabilized.
The 10.4-inch Retina iPad Pro comes with an extra 10-megapixel sensor on the rear, and with the same 8GB of memory as the mini.
The device also comes equipped with an optional 10.2-inch Quad HD display.
The 10.6-inch Air comes in two configurations, with either 8GB or 16GB storage.
The 13- and 15-inch iPads also come with an upgraded camera sensor and an upgraded processor.
The larger iPad Pro also comes packed with a much better camera sensor with f/1.7 aperture, while also offering a more advanced optical image stabilisation.
The camera has improved autofocus and image stabilization, and it can shoot 4K resolution video at 60 frames per second.
The 9.9mm iPad Air, meanwhile, has a much faster processor and has a 10-MP sensor.
The Air comes equipped a 10MP camera with a 1.5X optical zoom lens and an f/4 aperture, and has the same resolution as the iPad.
The 8GB and 16GB iPad Airs are available in both models, but you will need to pay extra for the 32GB iPad Pro.
There are also new iPads with a slightly higher screen resolution.
The larger iPad 11-inch comes with the 10-inch retina display, while its 16- or 20-inch models are available with a 13 or 16.3 inch display.

Indonesia tsunami December 2018
This article is more than 1 year old
Indonesia authorities raise Anak Krakatau volcano threat level
Threat status climbs to second-highest level with no-go zone extended and flights rerouted

Indonesia raises volcano threat level for fear of another tsunami – video
Authorities in Indonesia have raised the danger level for the volcano that triggered a tsunami on Saturday, killing hundreds of people, and extended the no-go zone to three miles.
Flights around the Anak Krakakau volcano were rerouted and the crater's status was raised to high alert, the second-highest level.
Sutopo Purwo Nugroho, a spokesman for the national disaster agency, said: "There is a danger of more eruptions. People [near the volcano] could be hit by hot rocks, pyroclastic flows and thick ash."

People are being moved away from Sumur on the island of Java, which was badly affected by the tsunami and was one of the last areas to be accessed by rescue teams.
Aulia Arriani with the Indonesian Red Cross said: "The restless mountain is making life unpleasant. I met a woman today who said having the volcanic ash around was like having chilli rubbed in her eyes."
People have been told to stay at least 1km (0.6 miles) from the coast in areas affected by the tsunami, which killed at least 430 people and displaced more than 20,000.
Rudy Sunendar, the head of the Indonesian energy ministry's geology department, said: "There's still a chance of a landslide, even under the sea level or on the sea level.
"We don't know exactly because we [have] not yet gone to the field. Based on the satellite imagery interpretation, there is collapse of some areas of Mount Anak Krakatau."
Huge waves hit the west coast of Java island and the south coast of Sumatra on Saturday, created by land shifting under water on the volcano. On Thursday, Sutopo urged those in the area to "remain calm and increase awareness" by taking heed of official information sources.

Earlier this week, the Indonesian Red Cross said its aid work in Banten province, one of the worst-affected areas, was being hampered by people becoming "jittery" due to rumours about further waves hitting.
A mosque in the area falsely announced that huge waves were arriving, causing panicking people to flee to higher ground.
Many people with missing family members have been submitting DNA samples to hospitals to see if they match those taken from bodies found but not yet identified.
Tubagus Cecep, 63, said he feared for his missing son. "They found a body, a pile of bags and my son's shoes," he said. "I'm still waiting for the body to be identified. We don't know yet if it was him."
Arriani said: "Many thousands of people are still living in neighbours' houses or on higher ground. Some are sleeping in mosques with no windows or doors, so they get cold at night. Yesterday's localised flooding drained, but it's a wait-and-see situation."
The disaster struck without warning in a country that regularly experiences landslides, earthquakes and volcanic eruptions. No earthquake activity had been felt beforehand, and the waves surged inland at night on a holiday weekend while many people were enjoying concerts or other beach and resort activities.

Radar data from satellites, converted into images, showed the Anak Krakatau volcano shrank dramatically following the eruption, Associated Press reported.
Satellite photos were not available because of cloud cover, but radar images from a Japan Aerospace Exploration Agency satellite, taken before and after the eruption, showed much of the volcano's south-western flank had gone.
Jaxa's post-eruption image showed concentric waves radiating from the island, which experts say is caused by continuing eruptions.
Dave Petley, the vice-president for research and innovation at Sheffield University, who analysed similar images from a European Space Agency satellite, said they supported the theory that a landslide, most of it undersea, caused the tsunami. "The challenge now is to interpret what might be happening on the volcano, and what might happen next," he wrote in a blog.

Last week a mystery bird from New Jersey rightly caused a fair bit of confusion among birders of the Garden State and beyond. The bird was a sparrow, that much was clear, but it didn't seem to fit any of the easily boxes the other North American sparrows can be fairly easily sorted into. Superficially, it resembled the Black-chinned Sparrow of the southwestern United States with its gray chest and chestnut streaked with black back. A bird like that would be a remarkable record for New Jersey, well, for anywhere in the eastern half of the continent for that matter, as the Black-chinned Sparrow does not have an established pattern of vagrancy outside of the Great Basin.
But a lot of things didn't quite add up for thet potential first state record. For starters, the bird was structurally wrong, with a much larger beak and a flatter head than than any Spizella. Plus those streaks on the head were a problem, as is the whitish belly. There's a little hint of white in the malar and throat too, which would seem to be a problem for the species Black-chinned Sparrow. It's clear that this bird was something different, but how does one go about trying to identify a bird that's not in the field guides?
Field identification of abnormal birds is fraught with peril. In my experience, I've noted how birders, particularly newer birders, can have a tendency to jump to conclusions when they see any sort of bird that doesn't match up perfectly with the picture in the field guide. We've been well trained, if inadvertently, by our Sibleys and Petersons to look for that type specimen every time, but within a given species there's as much variation between individuals as there is between individual people. Granted, it's not always on a scale we can readily appreciate, and we humans are much more attuned to the differences in each other because that's how we recognize friends, family, and celebrities on the street, but when a bird is even slightly different from the norm, it's generally the more expected species than the unexpected. As the old saying goes, "when you hear hoofbeats, think horses, not zebras".
This is not an easy bird, but it is expected. In it we can see things we recognize in other, more common, birds. Structurally, that long and low body, the pot-belly and the flat head. That slate-gray breast turning to white belly, the faint hint of a white-throat. Identification of abnormal birds such as this one is not an exact science, but this one seems to break down as one half White-throated Sparrow and one half Dark-eyed Junco. A hybrid.
The bird was immediately apparent to be as such largely because a similar bird has been visiting a feeder, and well-photographed, in Henderson County in western North Carolina for the last three winters. This NC bird shows a lot of the traits evident in the New Jersey individual but it illustrates the variety of ways White-throated Sparrow and Dark-eyed Junco genes can intertwine. The NC bird has a much more prominent white throat, as well as some white in the lores and in the undertail coverts. One could conceivably introduce the possibility of a back-cross (the parents of the bird in question being a hybrid and a full Junco), but at that point you're walking down a dangerous and speculative path. Connecticut birder Mark Szantyr, in a post to Birdfellow a few years ago, photographed some birds that seem to shows some evidence of being intergrades (as well as a much more "White-throat-y" hybrid). Once you know that hybridization between these two species is, as the great ornithologist Charles Townsend relates, "extensive", the possibilities are endless.
White-throated Sparrows and Dark-eyed Juncos are both exceedingly common winter residents across a great swath of the continent and their breeding ranges, in great part, lie right on top of each other, so it's sort of remarkable we don't run into these hybrids at feeding stations more often. David Sibley, in his seminal field guide, even illustrates this combination along with the Zonotrichias, though his illustration shows far more White-throated Sparrow traits than the New Jersey or the North Carolina bird. It should be enough to send birders to their feeding stations and hedgerows to look for these unusual birds, because they're out there. And once you feel comfortable tackling winter sparrow intergrades, well, then I can introduce you to the really weird stuff.
Ladies and gentlemen, I give you the "Durham Mystery Sparrow".
When I first looked at the 1st photo I thought Dunnock or Hedge Sparrow?
did you look at things like Black-Faced Bunting (Emberiza spodocephala)?
Looking that these birds (and the Durham bird) have caused multiple blood vessels in my brain to burst. A hybrid combo I've not even thought of…you win again birds, you win again.
We had a bird like this in Calgary around 20 years ago. Really had us going for a while till I got some pictures(film) and some experts got a look at them and solved the mystery. I didn't get any of the pictures back!
Fascinating! I'm surprised at the variation among the Dark-eyed Juncos at my feeder. Would love to see this!
Very interesting, and great photos. I thought you and your readers might also be interested in a possible Song Sparrow x Dark-eyed Junco I photographed in Utah last year.
A wonderful mystery bird, gets us out of the book! I have a Red Head Duck in my yard and bay for over a week now, hanging with a flock of Mallards and he is very interested in one of the Mallard hens to the point of sleeping next to her. The male Mallards don't seem to mind his presence. I wonder if he flew up here to No. Mn on the border with Can. together. Makes me wonder about possible cross breeding.
On the other hand as keeper of 21small species of birds in aviaries, I see lone birds like our male Rosey Bourke, very interested in a female Linneolated. The Linnie has a mate, along with another pair of Linnies, yet she constantly is found in the company of the Bourke. And when I let them out of the cage for some flight time, they stick together too. In or out, they sit together, talk, act like they are sharing food, etc.
Nature is very interesting folks, and birds know they are happiest in a flock, no matter if it is their own kind or not!

Carbon Credits per hectare from Native Forests.
Carbon Credits earned under the New Zealand Emissions Trading Scheme (ETS) are allocated based on predefined carbon sequestration lookup tables. Unless the forest is larger than 100 hectares, in which case the forest carbon is measured.
The carbon look-up tables cover all species and forest types under the ETS and assume that 1 tonne of carbon sequestered equates to 1 tonne of forest biomass (trees & roots) growth in the forest. Each tonne of carbon sequestered due to forest growth earns the forest owner 1 New Zealand Unit (NZU Carbon Credit).
This article will focus on the carbon sequestration rates of native forests in New Zealand.
It's important to understand that the MPI carbon look-up tables are a simplification of a complicated natural process. However, they are based on real measurement data of forest growth around New Zealand.
The current carbon look-up tables for native forests exist out to 50-years. This represents the point at which native sequestration rates plateau according to the MPI look-up tables.
The annual carbon sequestration rate beyond 50-years is currently treated as zero. This is to say that beyond 50-years, there is as much carbon being sequestered from the atmosphere from the developing parts of the forest, as there is being released from parts of the forest degrading and rotting away.
At first glance, this 50-year horizon may not appear to accurately reflect the long-term growth of a developing native forest.
It is important to remember they are a desktop simplification of a complex natural process that covers many native species, stand dynamics, and age class compositions. Not all native forests are the same.
There are many varying views on the accuracy of these current look-up table settings, but currently, it's all we have to work with under the ETS. The look-up tables may also be updated and extended by MPI in the future.
A detailed guide to look-up tables for forestry in the Emissions Trading Scheme can be found on the Ministry for Primary Industries (MPI) website, but here is a summary below of the first 50 years:
Carbon credits nz per hectare - Native forests
Tree Age (yrs)
Carbon credits per hectare
'Permanent Post-1989' forest
Native forest establishment in the Emissions Trading Scheme is categorised as a 'Permanent Post 1989' forest.
On 1 January 2023 the 'Permanent Post-1989' forest category is being added to the ETS, replacing the current category; Permanent Forest Sink Initiative (PFSI). Any existing PFSI forests will be transferred to the new category.
It is a requirement that 'Permanent post-1989' forests will not be clear-felled for at least 50 years after they are registered in the ETS.
'Permanent Post-1989' forests will be on the stock change accounting approach enabling them to earn Carbon Credits in line with the MPI carbon lookup tables, as long as the forest remains in the ground.
To fully understand the legal implications of registering a 'Permanent Post-1989' forest in the Emissions Trading Scheme, refer to the Ministry for Primary Industries website.
Forest Types
Permanent native forestry under the ETS also has two distinctive forest types which earn carbon credits at varying rates.
These variations are based on the previous land use (as at 31 December 1989) of the newly established native forest:
Bare land to native forest, i.e., Establishment on an ex-pasture site.
Ex-exotic forest to native conversion i.e., A harvested pine forest conversion to native forest.
The impact of establishing a native forest on a previously forested exotic site means that the forest does not earn any carbon credits for the first 10 years.
The reason for this is due to the look-up table assumption that the carbon remaining on the harvested site; locked up in the stumps and slash (above and below-ground woody biomass), rots away, releasing the carbon back into the atmosphere over 10 years.
Bare land vs Conversion Forest
Chart 1 compares the annual carbon credit allocation for both; the bare land establishment of a native forest, and the conversion establishment from exotic species to native forest.
It reiterates visually the impact of not receiving the first 10 years of carbon credits and displays the actual number of NZU's this represents.
Chart 1: Annual carbon credit allocation per hectare from a native forest
Chart 2 below compares the total accumulated carbon (sum of the annual allocation) for both establishment types.
It clearly shows the impact that establishing a native forest on an ex-exotic site has on the total carbon credit allocation out to 50-years.
Chart 2: Total accumulated carbon over the 50-year permanent native forest
Permanent Forests
Permanent forests are those left to develop and mature into perpetuity without ever being subject to harvesting activities. The beauty of permanent forests is that, unlike harvested areas, they will never incur a carbon liability due to harvesting activities.
This allows the forest owner to earn revenue, at very low risk, through the sale of the carbon credits earned from the forest. However, it is important to know that permanent forests are not exempt from all carbon liability risks.
Although the chances are very low, 'Acts of God' such as fire, landslide, or wind events, could damage areas of the forest causing them to be 'deforested' under the ETS definition.
Carbon Credits earned from 'Permanent Post-1989' forests will be tagged as such in the New Zealand Emissions Trading Register (ETR). This traceability back to the land title and forest type enables access to potential price premiums for native forest carbon credits in the voluntary offsetting market.
Permanent native forests also provide a wide range of intrinsic benefits, besides carbon sequestration.
Native forests increase water quality throughout the catchment where they are features of the landscape. Permanent native forests forever protect the soil from erosion, reducing the risk of flood damage, debris flows, and sediment discharge downstream. Native forests are also a hotspot for improving flora and fauna biodiversity in New Zealand; a commodity that is not yet monetised in New Zealand but has been in other parts of the world.
There are think-tanks at a government level discussing the creation of a biodiversity credit, or a similar incentive to encourage the establishment of new native forests across New Zealand.
Further protection of permanent native forests is available through 3rd party organisations such as the QEII National Trust.
Native forest registered under a QEII Covenant is registered against the legal title of the land ensuring the forest remains protected from land-use changes across generations and changing ownership structures. It's something we can do now to ensure protection

TVU's Modular, Microservice-based Approach Provides Production, Collaboration, and Live Streaming Capabilities Needed During the Pandemic
TVU Networks, the market and technology leader in cloud and IP-based live video solutions, recently provided their technology for remote sports proficiency testing and competition at China's elite Beijing Sport University. The university's School of Journalism and Communication students produced the collaborative live stream of university table tennis athletes completing their tests. Key products that enabled the proficiency tests were: TVU Anywhere, a mobile live-streaming app; the TVU Partyline cloud collaboration solution; and TVU Producer, a live streaming and multi-camera IP video production platform.
More than 50 students completed their tests, each creating an audio-video self-portrait with camera input from their smart phone or tablet. The TVU Anywhere live-streaming app allowed each student to transmit using HEVC encoding and cellular bonding technology to aggregate all ava
ilable cellular connections from their location. They entered TVU Partyline in groups of five to select contestants, referees, and timekeepers – each monitoring the action and collaborating live from their own window on the computer screen. The school's communication and journalism students managed the production using TVU Producer to switch signals for picture-in-picture presentation, add graphic overlays and text, and transmit content in HD quality through Bilibili – the Shanghai-based over-the-top streaming platform.
Liming Fu, TVU Networks VP of Sales for the APAC Region said, "TVU Networks is pleased to provide the university with our cloud-based solutions for streaming, collaborating, and producing this first-of-its-kind live virtual event. The students from the Beijing Sports University School of Journalism and Communication gained valuable experience in cloud production and broadcasting with this rare opportunity to practice in a real-world application. We will continue to support the university as they expand their capabilities and TVU technology to new types of applications."
Maintaining the highest possible live, HD transmission was critical to the university. Frame-accurate synchronization of the live broadcast images with the referee's whistle was necessary to ensure the competition's fairness. The TVU cloud service plan was ideal for the Beijing Sports Table Tennis Level Test, making planning and delivering the competition easy and infrastructure-free.

Chelsea Handler hits back at criticism that she's 'too aggressive' with her politics
Elizabeth Preza
Chelsea Handler is not shutting up.
On Wednesday, the outspoken comedian posting a picture on Instagram of herself flipping the bird, with the caption, "Fuck you Jeff Sessions, gorsuch, Steve Bannon and trump. Fuck all of you."
Apparently, a friend told her she was being "too political," and "too aggressive" in her criticism of the president and his team, to which Handler replied"
"I am a white woman of a lot of privilege. I make a lot of money and I don't have a lot of problems, and a lot of what this administration has proposed thus far won't even affect me personally," Handler confessed in her video. "I don't need Planned Parenthood, I can pay for my own medical care. I'm not an immigrant, I was born here. I'm not Muslim. I'm not Mexican. I'm not black. I'm not gay, or transgender."
Handler explained that she knows America is based on inclusiveness and welcoming people. She also said that as she understood it, the country is founded on loving people, despite differences.
It's about "not worrying about how something impacts your life personally, but how it impacts all the people around you and all the people that aren't around you," she continued. "It's compassion and it's empathy. And I will fight for it, and if I come off as being aggressive, it's because I care so much about doing the right thing."

A video posted by Chelsea Handler (@chelseahandler) on Feb 1, 2017 at 6:32am PST
President Donald Trump hurled insults at his former national security adviser John Bolton -- who could be called to testify against him in the Senate impeachment trial.
Bolton revealed in his forthcoming book that Trump explicitly tied Ukraine aid to an investigation of Joe Biden, and Democratic senators -- and possibly some Republicans -- want to subpoena him to testify in the trial.
"For a guy who couldn't get approved for the Ambassador to the U.N. years ago, couldn't get approved for anything since, 'begged' me for a non Senate approved job, which I gave him despite many saying 'Don't do it, sir,' takes the job, mistakenly says 'Libyan Model' on T.V.," Trump tweeted, "and many more mistakes of judgement, gets fired because frankly, if I listened to him, we would be in World War Six by now, and goes out and IMMEDIATELY writes a nasty & untrue book. All Classified National Security. Who would do this?"
Democrats are preparing for the possibility that President Donald Trump and his staff will sabotage their transition if he loses the 2020 election.
At least one outside group -- National Security Action -- has started making preparations for the Democratic campaigns in the event their candidate wins, and Elizabeth Warren has just released a plan that describes how she would quickly staff the government to smooth the transition if she won the White House, reported Politico.

Currently the site shows a series of five consecutive photos of a guy skiing off the roof of a house.
"A lucky few of us know that houses, garages, sheds and hotels yield far more potential than just simple shelters," says one of the Web site's pages.
But among these showboating antics there is also the latest competition news, a buy and sell page, and backcountry tips, as well as some other inspiring photos (if rooftops don't do it for you).
Their mission, as stated online, "is to become one of the funniest and sickest freeskiing sites out there."
The site, which cost less than $1 million, plans to zero in on the freeskiing scene both at home and overseas, focusing on the shenanigans at the heart of freeskiing.
"I'm stoked to see it growing as quick as it has," said Bond. "... and the more people that contribute, the closer skiers will come to taking over the earth once and for all."
The creators are asking people to send in their photos and stories to keep their site as sick as possible.
As for the name doglotion – for those non-freeskiers out there – a doglotion is also known as a mandatory straight line. Check out doglotion.com to find out about the doglotion contest for the picture of the best straight line.

Q: Point and Line class in c++? I'm learning C++ (and programming in general) and I'm trying to make both a Point class and a Line class.
A line should be composed of 2 point objects.
Can the C++ gurus look over my work and tell me if this is how you should appropriately use pointers, references and classes?
class Point
{
    private:
        int x, y;
    public:
        Point() : x(0), y(0) {}
        Point(int x, int y) : x(x), y(y) {}
}

class Line
{
    private:
        Point *p1;
        Point *p2;
    public:
        Line(Point &p1, Point &p2) : p1(p1), p2(p2) {}

        void setPoints(Point &p1, Point &p2)
        {
            this->p1 = p1;
            this->p2 = p2;
        }
}

A: You should not be using pointers at all in your code. Use actual objects. Pointers are actually used quite rarely in C++.
class Point
{
    private:
        int x, y;
    public:
        Point() : x(0), y(0) {}
        Point(int x, int y) : x(x), y(y) {}
}

class Line
{
    private:
        Point p1;
        Point p2;
    public:
        Line(const Point & p1, const Point & p2 ) : p1(p1), p2(p2) {}

        void setPoints( const Point & ap1, const Point & ap2)
        {
            p1 = ap1;
            p2 = ap2;
        }
}

A: Whether or not the Point members of your line class are pointers or not creates a very different type of class.  Using pointers will result in a classical CoGo style approach, which can be thought of as points being like nails in a board, and lines being rubber bands connecting those nails.  Changing a point is like moving a nail, all the associated line works automatically follows, which is desirable in certain applications.
Using literal points means that the lines are all independant of one another, which is appropriate to other types of application.
This is a critical design decision for your classes at this stage.
Edit: As noted in other posts and the comment below, utilising simple pointers to achieve association between multiple lines and points also presents a serious potential problem.  Specifically, if a point is deleted or moved in memory, all the pointers referring to that point must be updated.  In practice, this tends to be overcome by using unique point IDs to look up a point rather than simple pointers.  This also allows the CoGo structures to be easily serialized / saved.  Thus our point class would have a static member to get a point based on ID, and our line class would have two point IDs rather than pointers.

A: +1 what zabzonk said.
The time to use pointers, as you have used them, would be:

*

*You have several points

*You want to create lines using those points

*You want to change the values of the points and have the lines changed implicitly.

Step 3 above can be achieved if lines contain pointers to existing points. It introduces complexity though (e.g., "when you destroy a Point instance, what happens to Line instances which contain pointers to the Point?"), which doesn't exist when (as zabzonk suggested) each Line contains its own Point values.

A: I would prefer this...
class Point
{
    private:
        int x, y;
    public:
        Point() : x(0), y(0) {}
        Point(int x, int y) : x(x), y(y) {}
}

class Line
{
    private:
        Point p1;
        Point p2;
    public:
        Line(const Point &p1, const Point &p2) : p1(p1), p2(p2) {}

        void setPoints(const Point &p1, const Point &p2)
        {
            this->p1 = p1;
            this->p2 = p2;
        }
}

A: There is no need to use pointers in your Line class.
Also, the following line is incorrect:
Line(Point &p1, Point &p2) : p1(p1), p2(p2) {}

Why?  You are assigning a Point & (p1) to a Point * (Line::p1), which is illegal.  You'd want pointers there.
Your Point class has no way to modify its data.  Not too useful...
A Line class for me would look something like this:
class Line
{
    private:
        Point p1, p2;

    public:
        Line()
        {
        }

        Line(Point start, Point end) :
            p1(start), p2(end)
        {
        }

        const Point &startPoint() const
        {
            return p1;
        }

        Point &startPoint()
        {
            return p1;
        }

        const Point &endPoint() const
        {
            return p2;
        }

        Point &endPoint()
        {
            return p2;
        }
};

You can now edit your line like this:
Line line;
line.startPoint() = Point(4, 2);
line.endPoint() = Point(6, 9);

A: A couple of things I noticed :

*

*You can combine both of your point constructors into a single constructor with default values.

*Your usage of pointers is quite unnecessary. Use the object itself.

*You're using both pointers and references interchangeably. Don't mix them up, or see the last point.

A: I see little value in making Point's pointers (other than for irony value).  Your Point takes 8 bytes on a 32 bit system (2 int's).  A pointer takes 4 bytes.  you're saving 4 bytes.
As for correctness, your Line constructor takes references, but you're assigning them to pointers.  That shouldn't even compile.  You're also doing the same thing in setPoints.  It would be better to simply make the two points actual objects and copying their values.

A: class Line
{
    private:
        Point *p1; /* No memory allocated */
        Point *p2; /* No memory allocated */
    public:
        Line(Point &p1, Point &p2) : p1(p1), p2(p2) {}

        void setPoints(Point &p1, Point &p2) /* passed references to Point objects */
        {
            this->p1 = p1; /* asssiging Point objects to Point *! */
            this->p2 = p2; /* asssiging Point objects to Point *! */
        }
}

The setPoints() function wouldn't work - at first glance.
It should be
            void setPoints(Point &p1, Point &p2)
            {
                this->p1 = &p1; /* asssiging Point objects to Point *! */
                this->p2 = &p2; /* asssiging Point objects to Point *! */
            }

Then again, we don't have control over when p1 and p2 get destroyed. It's better to create this->p1 and this->p2 using the data in p1 and p2 so that the destructor has control over the memory

A: The compiler will give errors on this code:

*

*In the initialisation list of the Line constructor, you are assigning Point reference p1 to class member p1, which is a pointer to Point. To get this to compile, you should use Line(Point &p1, Point &p2) : p1(&p1), p2(&p2).

*The same problem occurs in the setpoints method. That shoudl be changed to this->p1 = &p1, etc.

*Minor issue: after the closing } of the class, put in a semicolon (;)

I think that concludes the syntax.
There is another issue with the code:
The p1 and p2 class members of Line are pointers to Point instances. Who creates these instances and who will delete them when they are not needed anymore? If you design your class as it is now, the code that creates a Line instance passes two Point instances to the constructor. If these Point instances are deleted before the Line is, the Line is left with two dangling pointers (pointers that no longer refer to a valid instance).
Also, the two Point instances that are now part of the Line can be modified from code outside of the Line class. This can lead to very undesirable situations.
In this situation I would declare the p1 and p2 members as Point (instead of a pointer to Point). That way, the Point instances that are passed to the constructor are copied to the class members. As long as the Line exists, the Point members will exist. They can only be changed by the line class itself.

A: Before asking about the language guru's opinion, start thinking about the design, in this case especially about the lifetime of your objects: does a point need to exist without a line?  Do lines share points?  Who creates a point, when does it stop to exist?  Are two points with the same coordinates identical, or just equal (one might be red, the other might be blue)? ...
It appears that most here agree that you should use value-semantics on such a small code base.  Sometimes, the problem requires the same object (i.e. Point) to be referenced by many sides, then use pointers (or references).
The choice between a pointer and a reference is still something else.  I prefer using a reference when implementing aggregation (a line can't exist without it's endpoints), and a pointer when implementing a less 'intimate' relation.

A: Use Point objects in your Line class. The ownership of the points is unclear and you risk ending up with dangling pointers or leaked memory.
Your default constructor is a problem as you will rarely want to create a Point at (0,0). You are better off setting the default x,y values to something like MAXINT and asserting that any use of Point doesn't have MAXINT as one of its values. Have an is_valid()  function so that clients can test. Your Line class can also have a precondition that its two points are not invalid. The pay off of not allowing a valid point to have a MAXINT value is that you can detect when Points have not been initialized properly, and you'll zap out some otherwise difficult to find bugs in the class usage.

Particle Physicists begin to invent reasons to build next larger Particle Collider
Collider quilt. By Kate Findlay.
[Image: Symmetry Magazine]
Nigel Lockyer, the director of Fermilab, recently spoke to BBC about the benefits of building a next larger particle collider, one that reaches energies higher than the Large Hadron Collider (LHC).
Such a new collider could measure more precisely the properties of the Higgs-boson. But that's not all, at least according to Lockyer. He claims he knows there is something new to discover too:
"Everybody believes there's something there, but what we're now starting to question is the scale of the new physics. At what energy does this new physics show up," said Dr Lockyer. "From a simple calculation of the Higgs' mass, there has to be new science. We just can't give up on everything we know as an excuse for where we are now."
First, let me note that "everybody believes" is an argument ad populum. It isn't only non-scientific, it is also wrong because I don't believe it, qed. But more importantly, the argument for why there has to be new science is wrong.
To begin with, we can't calculate the Higgs mass; it's a free parameter that is determined by measurement. Same with the Higgs mass as with the masses of all other elementary particles. But that's a matter of imprecise phrasing, and I only bring it up because I'm an ass.
The argument Lockyer is referring to are calculations of quantum corrections to the Higgs-mass. Ie, he is making the good, old, argument from naturalness.
If that argument were right, we should have seen supersymmetric particles already. We didn't. That's why Giudice, head of the CERN theory division, has recently rung in the post-naturalness era. Even New Scientist took note of that. But maybe the news hasn't yet arrived in the USA.
Naturalness arguments never had a solid mathematical basis. But so far you could have gotten away saying they are handy guides for theory development. Now, however, seeing that these guides were bad guides in that their predictions turned out incorrect, using arguments from naturalness is no longer scientifically justified. If it ever was. This means we have no reason to expect new science, not in the not-yet analyzed LHC data and not at a next larger collider.
Of course there could be something new. I am all in favor of building a larger collider and just see what happens. But please let's stick to the facts: There is no reason to think a new discovery is around the corner.
I don't think Lockyer deliberately lied to BBC. He's an experimentalist and probably actually believes what the theorists tell him. He has all reasons for wanting to believe it. But really he should know better.
Much more worrisome than Lockyer's false claim is that literally no one from the community tried to correct it. Heck, it's like the head of NASA just told BBC we know there's life on Mars! If that happened, astrophysicists would collectively vomit on social media. But particle physicists? They all keep their mouth shut if one of theirs spreads falsehoods. And you wonder why I say you can't trust them?
Meanwhile Gordon Kane, a US-Particle physicist known for his unswerving support of supersymmetry, has made an interesting move: he discarded of naturalness arguments altogether.
You find this in a paper which appeared on the arXiv today. It seems to be a promotional piece that Kane wrote together with Stephen Hawking some months ago to advocate the Chinese Super Proton Proton Collider (SPPC).
Kane has claimed for 15 years or so that the LHC would have to see supersymmetric particles because of naturalness. Now that this didn't work out, he has come up with a new reason for why a next larger collider should see something:
"Some people have said that the absence of superpartners or other phenomena at LHC so far makes discovery of superpartners unlikely. But history suggests otherwise. Once the [bottom] quark was found, in 1979, people argued that "naturally" the top quark would only be a few times heavier. In fact the top quark did exist, but was forty-one times heavier than the [bottom] quark, and was only found nearly twenty years later. If superpartners were forty-one times heavier than Z-bosons they would be too heavy to detect at LHC and its upgrades, but could be detected at SPPC."
Indeed, nothing forbids superpartners to be forty-one times heavier than Z-bosons. Neither is there anything that forbids them to be four-thousand times heavier, or four billion times heavier. Indeed, they don't even have to be there at all. Isn't it beautiful?
Leaving aside that just because we can't calculate the masses doesn't mean they have to be near the discovery-threshold, the historical analogy doesn't work for several reasons.
Most importantly, quarks come in pairs that are SU(2) doublets. This means once you have the bottom quark, you know it needs to have a partner. If there wouldn't be one, you'd have to discontinue the symmetry of the standard model which was established with the lighter quarks. Supersymmetry, on contrast, has no evidence among the already known particles speaking in its favor.
Physicists also knew since the early 1970s that the weak nuclear force violates CP-invariance, which requires (at least) three generations of quarks. Because of this, the existence of both the bottom and top quark were already predicted in 1973.
Finally, for anomaly cancellation to work you need equally many leptons as quarks, and the tau and tau-neutrino (third generation of leptons) had been measured already in 1975 and 1977, respectively. (We also know the top quark mass can't be too far away from the bottom quark mass, and the Higgs mass has to be close by the top quark mass, but this calculation wasn't available in the 1970s.)
In brief this means if the top quark had not been found, the whole standard model wouldn't have worked. The standard model, however, works just fine without supersymmetric particles.
Of course Gordon Kane knows all this. But desperate times call for desperate measures I guess.
In the Kane-Hawking pamphlet we also read:
"In addition, a supersymmetric theory has the remarkable property that it can relate physics at our scale, where colliders take data, with the Planck scale, the natural scale for a fundamental physics theory, which may help in the efforts to find a deeper underlying theory."
I don't disagree with this. But it's a funny statement because for 30 years or so we have been told that supersymmetry has the virtue of removing the sensitivity to Planck scale effects. So, actually the absence of naturalness holds much more promise to make that connection to higher energy. In other words, I say, the way out is through.
I wish I could say I'm surprised to see such wrong claims boldly being made in public. But then I only just wrote two weeks ago that the lobbying campaign is likely to start soon. And, lo and behold, here we go.
In my book "Lost in Math" I analyze how particle physicists got into this mess and also offer some suggestions for how to move on.

I do not accept that naturalness is dead. Only people that postulate unfounded hypothesis can claim it is dead.
The higgs mass is natural if there are no heavier particles.
So naturalness is dead if we find heavier particles. If we do not we can conclude that naturalness seems reasonable. Naturalness predicts no heavier particles.
Sabine Hossenfelder 9:06 AM, April 04, 2018
Matti,
It's the other way round. The Higgs mass is unnatural if there are no heavier particles (with certain properties).

how does not finding SUSY @ LHC and collapse of naturalness affect the credibility and claim of string theory as the only game in town. should string theory continue to attract priority mainstream research at top universities to the exclusion of other approaches like LQG?

CF3 groups have an 18.3° torsional angle from staggered positions. This reduces molecule point group symmetry from T_d (achiral) to T (perfectly geometrically chiral). (H3C)3C-CF3 (2 debyes, prolate top) and certainly (F3C)3C-CH3 (1.9 debyes, oblate top) microwave rotational spectra are extreme tests of baryogenesis' Sahkarov conditions - universal trace vacuum chiral anisotropy toward hadrons (quarks). If enantiomers' cryogenic rotational spectra are not exactly identical and exactly superposed, 50 years of physical theory is empirically falsified. Baryogenesis, Milgrom acceleration, and the cosmological constant are sourced. The Equivalence Principle can be violated. Einstein-Cartan gravitation is viable. SUSY and M-theory are defective

neo,
I answered this question here.

I'm baffled by that statement. The LHC could perfectly well discover new phenomena which would make the Higgs mass "natural". The fact that run 1 and run 2 gave no evidence is SUSY is irrelevant. The LHC has only taken a small fraction of the data it will take during its lifetime. It hasn't killed the idea of naturalness regardless of what may or may not appear in the arxiv and at conferences.
Sabine Hossenfelder 12:51 PM, April 04, 2018
etoona,
The higher the masses of the superpartners, the more you have to bring finetuning back. Of course you can argue that a factor 10 is permissible. Or maybe a factor of 100. Or 1000? Really the only thing this shows though is that naturalness isn't mathematical criterion to begin with.
Having said that, as I wrote explicitly, you are right of course that it might indeed be there are new discoveries waiting in the data. My point is there is no reason to expect it.

This is not relevant to the post itself, but I have to ask: can anyone make sense of Uncle Al's comments? What does the chirality of some organic molecules have to to with SS? For a while I thought it was a bot and the "AL" was actually "AI", but alas.

I'm guessing the Chinese would want to build this collider for non-scientific reasons.
And from the Physics POV, it _might_ find something.

I do not really understand the naturalness as a concept if it's just about some constant being of order one. I have a super natural theory proposal: I just encode all the current observables into the decimal parts of 1.something. When a new observable comes I just append it into this number.
Thus my theory is insanely natural. Only one constant that needs to be fixed by observations. Sure it will not predict anything, but after the fact it will fit to any observable ever.
Because of this one would think that Kolmogorov Complexity (https://en.wikipedia.org/wiki/Kolmogorov_complexity) would be better fit for any naturalness argument. Basically the simpler the number the better it is. 10^-120 has far lower complexity than 1.12458912839182389219579128371285321876487781296389127637654 as an example. Do note that Pi is also a really simple number as there is a small algorithm to produce all the decimals, but even so it is more complex than 10^-120.
In essence the total complexity of a physical theory is roughly all of it's constants plus all the formulas it has. To minimize this has some informational theoretical basis, not just some constant being on order one.

Hi thanks
Yes i read it. What I had in mind is new faculty hiring and positions, courses offered at top universities. Should all the new positions in theoretical physics, quantum gravity be offered solely to string theorists, or should theorists in other approaches to QG be hired, in light of LHC and naturalness and SUSY.
Should top physics departments now offer LQG and emergent gravity courses to physics majors like do for string theory?
fulis,
I think he is arguing that (molecular) chirality affects the equivalence principle. Or at least that's what I am guessing. Uncle is basically part of the family; he has been commenting on this blog ever since. What he writes rarely makes sense to me, but he is usually brief and doesn't bother others, so I tend to approve a comment or two per post. Maybe it's just because I don't have any actual uncles ;)
sharpneli,
In principle I think that's a good idea. I've toyed with that and over the years I've noticed (as it often goes with these things) that some others have too. The obstacle is practical: Most of the numbers we have consist of only a few digits, so they are simple according to any measure. In any case, you are more than welcome to try this, please let us know what you find :)
(I do not know if I doublepost this since I got an error on my first post. )
I was taught that the correction to higgs mass squared was related to the mass^4 of the other particles.
What should the mass correction be according to you? I would like this input to ask my phd contacts in theoretical physics about what I understood wrong.
Lawrence Crowell 6:06 AM, April 05, 2018
Supersymmetry is a framework that relates Lorentz symmetry of spacetime to spin or spinor quantum theory. There is absolutely nothing in this structure that says supersymmetric partners must occur at collider energies accessible by us. For all we know SUSY could be a string or near Planck scale physics that has little or nothing to do with particle physics in the TeV range of energy.
A bigger concern I see is not so much theoretical complexity, but experimental complexity. This next generation of particle collider approaches the size of an small to average sized nation and has enormous costs. It also takes physics effectively little closer to the Planck scale. It seems a premium should be put on finding new ways to accelerate particles, such as maybe with lasers, or by using natural phenomena such as cosmic rays or maybe subtle signatures in gravitational radiation.
The correction (to the square of the Higgs mass) that are relevant for the naturalness problem is the divergent term that (after mass renorm) scales with the cutoff square. Ie, it's (supposedly) of the order of the Planck mass square, hence much larger than the mass of the Higgs (square) itself. The explanation on wikipedia looks largely correct.
Uli Thomsen 6:22 AM, April 05, 2018
WTF else should they do to secure their jobs and reputations on a 'business as usual' base without beeing forced to admit, that they cling to a 'not even wrong' theory (let's better say: 'hypothesis') for half a century by now? It reminds me to a running gag in a video, hardly familiar outside Germany, that goes: "Same proceedure as LAST year? - Same proceedure as EVERY year!" The decision to buildt a new, larger, stronger accelerator, whicjh takes decades, would secure them until their retirement - publishing even weirder and stranger hypotheses of how the universe may work - insteadt of working out alternative theories of quantum gravtation as LQG or CDT or whatsoever. The SuSy and the ST/MT seem to have failed - so lets look for other promising approaches to quantum gravity! Let's boldly go where no one has gone before... ;-)
Sometimes it is complained that this argument depends on the regularization scheme introducing the cut-off Λ {\displaystyle \Lambda } \Lambda and perhaps the problem disappears under dimensional regularization. In this case, if new particles which couple to the Higgs are introduced, one once again regains the quadratic divergence now in terms of the new particle squared masses. For instance, if one includes see-saw neutrinos into the Standard Model, then δ m h {\displaystyle \delta m_{h}} {\displaystyle \delta m_{h}} would blow up to near the see-saw scale, typically expected in the 10 13 {\displaystyle 10^{13}} {\displaystyle 10^{13}} GeV range.
It does sound like the last paragraph in what you linked me is similar to what my friend said. I.e. the correction is related to the mass of the other particles.
The leading correction depends on the masses of the other heavy particles after you have gotten rid of the cutoff contribution, but you need those additional particles (and cancellations between them, eg because of susy) to get rid of the contributions to begin with. No particles, no solution to the naturalness problem. That's the reason so many particle physicists thought the LHC would see something new, exactly because if the new particles are too heavy you get back a finetuning issue from their contributions to the Higgs mass.
Matti Jansson 10:27 AM, April 05, 2018
It kinda sounds like the normal infinities you get for all particles. What is the reason to not just explain it away using renormalization?
I do feel I have enough to talk to my phd contacts again.
@Fulis, @Sabine.
… 1) Baryogenesis happened, violating deep conservation laws.
… 2) The universal violations are Sakharov conditions - thereafter ignored.
… 3) One condition is parity violation, trace vacuum mirror asymmetry, vacuum chiral anisotropy.
… 4) Physical theory is forever curve fitting parity and other chiral symmetry breakings because theory postulates the vacuum is exactly mirror-symmetric; "beauty" demands it.
… 5) A left foot is not identically fit by a pair of opposite shoes. The right shoe fits with a larger energy cost.
… A) Two masses embedding in vacuum with non-identical energies have non-identical minimum action trajectories - Equivalence Principle violation.
… B) Baryogenesis is sourced (postulated Sakharov conditions).
… C) Noetherian conservation of angular momentum requires exact vacuum isotropy. Universal vacuum trace chiral anisotropy - everywhere matter exists - universally leaks Milgrom acceleration. No dark matter.
… D) The cosmological constant "naturally" appears, DOI:10.3847/0004-637X/829/1/47, arXiv:1607.01128
… E) SUSY is fundamentally wrong. M-theory achiral gravitations, and all other archiral gravitations, are defective.
… F) A molecule (~0.2 nm³ chiral emergence) whose mirror images are maximally non-identical (opposite shoes) will energetically non-identically embed in chiral vacuum (a left foot). Their microwave rotational spectra (3-300 GHz, 0.144-144 kelvin; vibrations begin 10-fold higher in energy) are not exactly identical and/or not exactly superposed. To exceed spectral resolution, use a 3:1 ratio (right-handed)/(left-handed) mixture. Unresolved line broadening will be 3:1 asymmetric. The enantiomeric molecules are opposite shoes differentially embedded in chiral anisotropic vacuum background (a trace left foot).
… G) 50 years of physical theory are empirically falsified at the postulate level.
The sure thing observation - good or bad - is a polycyclic (multiply-connected), rigid with no flexible or spinnable substructure (sharp rotational transition lines), low molecular weight (intense transition), extreme geometric chiral divergence (calculable), polar (quantized rotation is an EM dipole transition), prolate top (calculable spectral lines) molecule. It requires a commercial chirped pulse FT microwave spectrometer (brightspec.com, 40,000:1 S/N), a vacuum supersonic expansion port to create a cryogenic molecular beam (14 kelvin or lower), and one hour. Dr. Melanie Schnell has one.
http://www.mpsd.mpg.de/59126/Research
… Wrong molecules for calculated maximum output divergence,
If one symmetric sharp line is seen, the foregoing is not explanative.
If one 3:1 asymmetrically broadened line is seen, gravitation, particle theory, the Big Bang, and the universe are tightly explained. One hour in commercial equipment. Using nitrile, -CN, as the polar substituent introduces nitrogen hyperfine coupling. The spectral line, with an added triplet, is self-calibrating.
Extreme molecular probes, including literature efficient synthesis of gram amounts in direct 3:1 chiral ratio from a common inermediate, are
2-cyano-D_3-trishomocubane (4.2 debyes, CHI = 0.885)
2-trifluoromethyl-D_3-trishomocubane (2.0 debyes, CHI = 0.916)
(The first must be dilute in vacuum versus polar dimers and has a low vapor pressure. The second is volatile and monomeric, but must be cold to suppress trifluoromethyl spin, The 2-fluoro has lowered CHI and dipole moment.)
A good idea need only be testable. It is believable afterward – the opposite of contemporary physical theory. That is why it fails (re OPERA superluminal muon neutrinos).
@Lawrence Crowell said...
does SUSY then make testable predictions that can be falsified?
how is SUSY broken, and again, does SUSY breaking then make testable predictions that can be falsified?
if not, then perhaps other lines of research that can make testable predictions should be pursued
Because the dependence on the cutoff is quadratic. (Rather than logarithmic.)
Louis Tagliaferro 3:50 PM, April 05, 2018
Is it me or some of the others who missed your point? I thought you were mostly arguing there are more promising areas for research and resources, that scientist need to recognize it. Just because something is not disproved doesn't mean it's reasonably viable; it's often been said (correctly) just because god's existence can't be absolutely disproved doesn't mean it's rational to believe he exists either.
I believe it usually comes down to human behavior (emotion). I don't think enough researchers realize or see the parts of their arguments that are swayed mostly by faith in their belief, what is not a purely scientific or fact based rational.
@Uncle Al,
I like to read the comment section and have been here a while. Like Fulis, I almost never understand much of what you write and I'd like too. You may not want to write at a lesser more explanatory level, but if you do I'd appreciate understanding a bit more of what you say.
Frank Potter 5:13 PM, April 05, 2018
"Finally, for anomaly cancellation to work you need equally many leptons as quarks,..." This decades old idea is not the only way to have anomaly cancellation. For example, suppose there are 3 lepton families and 4 quark families, then if each family represents a different discrete symmetry subgroup of SU(2), one can calculate lepton mixing angles and quark mixing angles that agree with the empirically determines values. Consequently, all 3 lepton families are acting collectively to mimic SU(2) and also all 4 quark families would be acting together to mimic SU(2). Therefore, direct anomaly cancellation via collective lepton SU(2) with collective quark SU(2).
Of course, both approaches have problems. The old way of matching one lepton family to one quark family does not dictate which lepton family to which quark family because any matching will work, and there is no inherent limitation on the number of quark families. And the new way requires 4 quark families exactly of which we have no evidence for a 4th quark family. However, a 4th quark family could possibly solve several problems, including the BAU origin by increasing the Jarlskog value by about 13 orders of magnitude.
Lawrence Crowell 8:12 PM, April 05, 2018
Most of the predictions of SUSY are within some model of gauge fields and fermions. The standard model of electroweak interactions plus QCD is the usual. SUSY can be made to predict loads of different stuff with different models. Back the the standard model issue the theoretical interest is that SU(3)xSU(2)xU(1) with SUSY has a renormalization group flow that converges to a common value for the coupling terms for these interactions. This occurs at around the GUT to Planck energy and is called the gauge hierarchy. So within this model there are then predicted superpartners of the fermion and vector particles. There are also additional Higgs fields as well.
These particles should get their mass from the Higgs field, which is extended with SUSY. The masses of these super partner particles can't be too far out of line with the maximum mass for the Higgs. The Higgs field has a quartic potential and if the bare mass is too large it is not possible to control the renormalized mass to GeV-TeV range. The mass goes to the Planck mass, so we are not likely to have a TeV mass Higgs particle. The bugger of it all is the LHC is not yielding any clue about the scalar top quark (stop) or Higgs particles. There is a slight diphoton production excess that is tantalizing, but there is not enough signal to draw firm conclusions. These experimental front has not been kind to a lot of theory and a whole lot more phenomenology.
So there is potentially a lot of open room here. I think SUSY, as a relationship between quantum and spacetime physics, may have some relationship to entanglement entropy and spacetime. Could Verlinde's dark matter interpretation be transformed into a SUSY picture where the two are aspects of some general system? With SUSY and string theory, what bearing do these have on LQG and dynamic triangulation? If LQG is false then why would something so close to general relativity be completely wrong? Conversely, string theory with its enormous mathematical richness, should that turn out to be completely false we might ponder how that might be. Which of these, string vs LQG and related, constrain the other, or is no relationship at all? I don't hold religiously to any of these as absolute; they are all grist for the mill.
David Brown 8:13 AM, April 06, 2018
"The standard model, however, works just fine without supersymmetric partners."
According to Burton Richter, fundamental progress in theoretical physics tends to come from simplification — and supersymmetry does not seem to be simplification.

@Lawrence
a theory with as many free parameters as SUSY it shouldn't be surprising there is gauge coupling. and if a GUT scale collider discovers there is no gauge coupling, would this falsify SUSY?
these additional higgs fields have not been found.
what observation would falsify the SUSY framework?
how is SUSY broken, and does this sector make detailed predictions a collider can falsify?

Uncle Al also comments on chemistry. On the things I was a specialist in,
his blatherings were not nonsense, just strange. Sometimes he was actually correct!
But this was not recently. I think he may well be actually correct about the meaning of rotational spectra of chiral molecules. And the lines are so very, very sharp
that with a big enough apparatus ... maybe interesting. Numerically I know nothing (and suspect he doesn't know either) about how big is needed. Note that lower dipole moments make sharper lines, harder experiments, bigger apparatus.
David Schroeder 9:16 AM, April 07, 2018
It is in the nature of our species to explore the unknown. When Christopher Columbus set sail with his small flotilla, he had no clue that he would discover a vast land area of 15.6 million square miles inhabited by millions of people ranging from hunter-gatherer groups to sophisticated civilizations with advanced knowledge of astronomy and architecture. Once again we are confronted with a Terra Incognita; though likely, as with Columbus, other civilizations throughout the Cosmos have already explored this unknown territory.
It would be wonderful to have a global initiative in which interested nations contribute whatever they can afford towards the construction of a new generation particle collider. Once such a machine is constructed our modern day 'lookouts' will be searching for bumps in the data, just as Columbus, and his crew, looked for bumps on the horizon indicating new land. The same excitement that those intrepid explorers of five centuries past felt on sighting an island in the Bahamas, will be felt by our modern day explorers should they initially find a single new particle, perhaps a member of a small 'archipelago' of particles. With any luck, later explorations, at higher energies, might reveal an entire 'continent' of new particles, and the champagne will be flowing freely!
A big "thank you" to Dr. Hossenfelder for letting us discuss an empirical approach to understanding physical theory.
@Unknown I created structural chemistry that fully reduced to practice Petitjean's n-dimensional quantitative chiral divergence and its normalized measure CHI. His Chemistry Department got him to CHI = 0.68. I repeatedly did CHI = 1. Success required not math but perspective. Those structures were the inputs to Novack's DFT paper, below.
The rules for CHI = 1 are explicit, as is their one exception. If CHI=0.9996 is close enough for you...what rules? Microwave experiment structures walk another path to CHI~0.9. Protein amino acid phenylalanine is CHI = 0.058600. A guppy is every bit the miracle of life that is a whale - but the whale us bigger.
Chiralanes have non-planar Schlegel diagrams re Kuratowski's theorem [subgraph homeomorphic to K_5 or K_(3,3)]. They also have a central tetrahedral carbon atom with four identical substituents that is perfectly chiral. There is no possible consistent nomenclature that labels the sense of handedness. Godel's theorem incarnate?

"blatherings were not nonsense, just strange" If it is obvious to one skilled in the art, it is not patentable. Tell us how to make a 30 wt-% solution (single molecules) of copper phthalocyanine in Plexiglas as a masterbatch dye. That was one part of a pre-funded $million project. The VP R&D flushed crimson and yelled "GODDAMNIT! It CAN'T work that way!" I gave him 500 g of the stuff, net cost of materials and processing about $300. Perhaps he was wrong.
"Sometimes he was actually correct!" The microwave experiment's output might be extraordinary or crap. Everything leading up to it is literature flawless doable in every way. The apparatus is commercial at brightspec.com, so look at the pictures re its size. FT microwave spectrometers are now compact. In-process sample size can be nanograms. Literature synthesis is net grams.
Look. "GODDAMNIT! It CAN'T work that way!" Physical reality is not a peer vote.

Actually, he died decades later while still convinced that he had reached "India".
Those opposed to his original exploid argued that the world was much bigger than Columbus believed and that his expedition would have starved long before they would reach India. As it happened, Columbus and his expedition nearly starved before they reached the Caribic.
FaceMD 6:45 PM, April 07, 2018
As a lay person, I have not understood a whole lot of the ideas and theories presented in your blog, but have thoroughly enjoyed it nonetheless. As one who constantly encounters charlatans and professionals with conflicts of interest in my own field, I appreciate your honesty and skepticism of modern physics theories. I know this may be a laughable question from your perspective, but I wonder if you have any opinions of Andrew Thomas's ideas in his series Hidden in Plain Sight (especially his more "original" theories)?
FaceMD,
I do not know Andrew Thomas or the series which you mention, sorry.
you allow alot of off topic comments :(
yeah, sorry. I shouldn't have answered to that question about Uncle. But it's a recurring question (which I usually don't publish), so I thought it'd be worth a few words. You're right though, enough now.
Lawrence Crowell 10:49 AM, April 08, 2018
@ neo,
The so called free parameters in SUSY are only those of the gauge theory imposed on it. SUSY does have the property of doubling things with particles and their super-partners. As for breaking SUSY, I am only really familiar with the Fayet Iliopoulos, which adjusts the Hamiltonian to a value other than zero. As for falsifiable, SUSY may only be falsifiable at Planck scales. Below that, and as far below as we probe nature, all we might be able to determine is if SUSY operates on this scale or not.
for your next blog post i'm intrigued by the claim that stacy mcgaugh's radial acceleration relation can be used to in conjunction with redshift to distinguish dark matter vs modified gravity, MOND in the paper you wrote.
what does dark matter predicts in the redshift of RAR vs MOND
what is needed to measure this redshift of the RAR
sounds like a nobel prize to me :)
No, there's no Nobel prize here. For all I have seen of particle dark matter simulations you can make these fit any redshift dependence. The reason for writing the paper was just to prompt them to at least make these calculations before the measurements actually come in.
Thanks, that makes sense to me.

neo 12:49 PM, April 09, 2018
ok thanks, but what redshift does MOND predict in RAR then?
could observation of certain values of the redshift in RAR rule out MOND?
Sabine Hossenfelder 1:01 PM, April 09, 2018
You can make MOND redshift-dependent in the same way that we made Verlinde's model redshift-dependent, by assuming that the acceleration constant that enters is actually related to the Horizon-size, which depends on the redshift. If you do that, the redshift-dependence is small, and the curves look very similar to the ones we plot for CEG in the paper.
But you don't have to rule out MOND because MOND has long been ruled out. It doesn't work on cluster scales, it doesn't work in the solar system. You'd be beating a dead horse. We're talking about modified gravity. Not MOND.
Can you rule out modified gravity? Well, many variants of modified gravity have already been ruled out. You can rule out some more should it turn out that the RAR has a redshift-dependence which is significantly larger than what we predict in the paper.
The more interesting question you should ask is can you rule out particle dark matter. Or can you make it fit all and every measurement?
Eusa 1:07 PM, April 09, 2018
How about if dark matter is something between modified gravity and particles? "Zippers"?
Eusa,
I really think names are more confusing than enlightening here. Write down a theory and show it works, it really doesn't matter what you call it. As I have said several times already, mathematically the difference between particle dark matter and modified gravity isn't all that large. Modified gravity adds fields to GR, particle dark matter adds particles to the SM, but particles are fields and fields are particles.
I have an interesting question to ask for your next blog post
can you rule out particle dark matter? Or can you make it fit all and every measurement?
i'm sure you find this question interesting ;-)
IMO the combination of Stacy McGaugh's RAR and recent findings that dark matter only interacts gravitationally with baryonic matter is enough to rule it out
btw with MOND, i've heard that if you add dark matter along the lines of 2ev neutrinos and black holes it might be possible to get galaxy clusters to work, and MOND is not applicable to the solar system

We currently have a few spaces for pipers, snare drummers and tenor drummers to join the band.
What was once a group of strangers with a shared dream is now a family. Friends have been made for life. But we can still grow and are ready to welcome new members into the band.
1. Is there an age limit to join the band ?
No. As long as you can play you can join the band. We currently have people of every age in the band from school kids to too old to admit
2. Where are practices held ?
We have our National Practices in Blair Drummond. Regional practices take place all over Scotland – so there will be one near you.
3. Do I have to commit to Every event ?
No. We understand all band members have busy lives. We ask that you commit to as many events as possible, and as many practices as possible but nobody is expected to attend everything.
4. I don't play an instrument yet – do the band provide lessons ?
Sadly not. Due to the geographical spread of all the band members we are unable to offer lessons at this time
5. What equipment does the band provide for pipers ?
The band provide the cherished blue bonnet, the waistcoat, a pipe chanter, chanter reed, reed protector and a flag for your drones. Just as important though, help, support, advice and friendship, and the chance to March on the road to Independence.
6. What do pipers need to provide for themselves ?
Your own set of pipes, your own practice chanter, your kilt, ghillie shirt, belt, sporran, socks, flashes, shoes and cape. A willing attitude and a sense of humour.
7. What equipment does the band provide for drummers ?
The band provide the cherished blue bonnet, the waistcoat, the drum and harness. Just as important though, help, support, advice and friendship, and the chance to March on the road to Independence.
8. What do drummers need to provide for themselves ?
Your own drum sticks and practice pad, your kilt, ghillie shirt, belt, sporran, socks, flashes, shoes and cape. A willing attitude and a sense of humour.
9. I have a disability – can I still join ?
Yes, yes yes. We will do everything we can to accommodate any disability. Whether you need somebody to push your wheelchair or any other help we will find ways to help and support you
10. Am I good enough ?
We are not a competition band and don't ever intend to be. We are an open inclusive band and have players of a variety of abilities. Yes we need players to reach a minimum standard and will work with them to help them improve, but we don't expect Grade 1. We are just as interested in your personality, your willingness to fit in and your hunger for independence
11. How do I apply ?
In the first instance use the contact us button and we'll take it from there. You will be asked to submit a short video of yourself playing – nothing too serious (30 seconds on your phone will be fine).
If you would like to join us or just find out more information please get in touch.
