Two of the speakers who stood out to me were General Jack Keane and Senator Tom Cotton |
General Keane unparalleled analysis of threats facing America especially major geopolitical ones such as Russia and China demonstrated to me just how much of an expert one has to be to understand the complex issues which America must deal with to protect itself and free people around the world |
Senator Cotton spoke about the military and how his time there shaped him as the person who he is today which was inspiring because it showed how much sacrifice regular people make in service of their fellow citizens |
I want to thank the Straus Center for helping me with these amazing opportunities |
The time I spent learning from and with policy scholars and my peers in DC really reinforced the idea that Torah Jews have a unique perspective to offer the broader world and how a Torah perspective can have an impact on policy making in Washington |
At a recent presentation at the prestigious International Congress of Industrial and Applied Mathematics in Tokyo Marian Gidea association dean for STEM research and director of graduate mathematics at the Katz School revealed the results of a simplified mathematical model demonstrating that oscillating steel beams made of piezoelectric materials produce more energy when their motion is regular |
The research Energy Growth Dissipation and Control in Hamiltonian Systems is supported by a three year National Science Foundation grant which was awarded in July to investigate dynamical systems including applications to energy harvesting celestial mechanics and space mission design |
Piezo is the Greek root for pressure or push and piezoelectric describes a property of special solid materials that can convert energy from an applied pressure into an electrical charge |
The computer model was developed in collaboration with Tamar Leiser who wrote her honor thesis on the subject as a student at YU Stern School for Women and Katz School Mathematics Ph D student Samuel Akingbade as well as research collaborators from Georgia Tech and Polytechnic University of Catalunya |
The researchers created a framework in which two steel beams are hooked up to a capacitor and suspended over magnets |
When the vibration of the beams is stronger than the mechanical friction electricity is produced and stored in the capacitor |
What we discovered to our surprise is that the answer we got was the one we should have expected said Gidea |
The beams that keep moving in a regular fashion a periodic motion going back and forth accumulate more energy in comparison with the ones that move chaotically that is without any pattern Energy harvesting devices which produce electrical charges through external vibrations can be attached to skyscrapers trains or bridges and provide a source of unlimited renewable energy |
Piezoelectric energy harvesting is also the preferred method for use with wearable devices since it is the most capable of producing the power needed at a small scale |
The steel beams in the Katz School model were coated with ceramic the preferred material for this type of energy harvesting because of its low cost and effective piezoelectric properties |
The use of piezoelectricity stands to reduce or even eliminate the need for frequent charging of devices and batteries |
Consumers would no longer be burdened with having to be near an electrical outlet which would in turn conserve electricity |
This may be a critical advance for healthcare since these devices can be implanted in pacemakers to stimulate the heart said Gidea |

That a consequence of light slowing as it crosses the boundary from air to water causing the light to bend or refract |
The root of this simple phenomenon is the focus of a research paper recently published by Fredy Zypman director of the M A in Physics at the Katz School |
In his paper Permittivity from First Principles published in September by AIP Advances Zypman considers the explicit connection between refraction and its atomic origin and proposes a mathematical model to gain physical insight on permittivity a property related to refraction |
Refraction occurs when light moves from one substance to another changing speed and direction |
The index of refraction is the relationship between the speed of light in a vacuum and the speed of light in a substance |
Matter around us in plastics liquids our skin the air have characteristic electrical properties said Zypman |
When the electrical field travels from one medium to another light must adjust to the local environment |
That why we see shadows and reflections those rich sources of optical sensations all around us |
Transparent materials like glass water and diamonds refract more than air so that when light enters from air its path bends toward an imaginary line perpendicular to the water surface |
Because the index is uniform throughout a material the bending occurs only as the light crosses the boundary |
This commonplace refractive index according to Zypman depends on the atomic electric response of a material its polarizability or tendency to separate positive and negative charges to electric fields |
Another way of looking at polarizability is the tendency of a material atomic electrons to become distorted when the material is placed in an electric field |
The larger the electric polarization the larger the material permittivity or the property of a material that measures the opposition it offers against an electric field |
We aimed to produce a clear conceptual pathway between the atomic polarization and the familiar refraction he said The main focus of the study is to produce exact expressions for the permittivity to all orders of an electric field that is valid for any intensity of light and to compute the permittivity for typical materials Two weeks into a clinical rotation in the emergency department at St John Episcopal Hospital in Far Rockaway Queens Carin Gannon a student in the Katz School M in Physician Assistant Studies was put to the test |
A local man gashed his leg on a piece of glass and was rushed into the emergency department bleeding profusely |
After being rayed to make sure that the glass wasn t embedded in the wound he was wheeled back into the emergency department where Gannon and Abraham Oxilas a Katz School clinical assistant professor and Gannon supervisor at St John were waiting |
It had been two hours since the injury so Gannon knew that it hadn t started healing from within but it had been several months since she had practiced suturing in Oxilas course Clinical Skills and Procedures |
Seeing yellowish subcutaneous fatty tissue she washed her hands with soap put on a pair of sterile gloves and grabbed a suturing kit |
She squeezed sterile water into the wound and injected lidocaine seven times under the skin to numb the area |
Oxilas sewed the first stitch and then handed the needle to Gannon |
Under the watchful eye of Oxilas and the patient Gannon went to work |
I knew how to do it from working on a silicone model in class she said but I didn t want to let on that this was my first time suturing a live patient so I was like Okay I gotta jump in and do the best I can |
I had the confidence |
I just had to summon the muscle memory |
She took the suturing needle shaped like a crescent moon and held the two sides of the wound while she stitched |
Like needlework suturing can involve a variety of techniques |
Gannon used a method called the interrupted stitch where each stitch is tied off using a surgeon knot |
She pulled the knots tight enough to hold the two sides of the wound firmly together without squishing them up into a tent shape |
Most simple lacerations can be sewed in less than minutes but because the man needed seven stitches it took Gannon a half hour to finish closing the wound |
It looked better than the way I practiced it in class she said |
I know it one of those small things that PAs do every day but when it your first time doing it it very exciting to be able to perform those skills |
Gannon instructed the grateful patient to keep an eye out for signs of infection like redness streaking up or down his leg and to avoid using alcohol or hydrogen peroxide to clean the wound |
He was given a tetanus shot and went home with antibiotics |
Carin is very personable knowledgeable and quick to adapt to her environment said Oxilas |
Her prior hospital experiences have helped her thrive in the emergency room in her very first rotation and I couldn t be more proud of her |
Gannon does three hour shifts a week taking the subway at a m to Far Rockaway a three hour ride one way from the Bronx |
On the way in she listens to her favorite musicians Hozier and Noah Kahan and on the way home she writes up her notes on patient diagnoses tests procedures and medications since it fresh in her mind |
At the end of her clinical rotation she ll be tested in class on what she learned |
Oxilas said the Katz School PA program is exceptional for its commitment to educating PAs to become culturally competent so they can provide appropriate treatment to diverse communities that are lacking adequate health care |
Our students enthusiastically help patients in any way they can whether it be coming up with differential diagnoses creating treatment plans performing therapeutic and diagnostic procedures or completing even simple tasks such as grabbing a blanket for a patient he said |
Gannon said the Katz School PA program has taught her to think holistically about patient care the physical psychological emotional and spiritual dimensions of care that lead to recovery |
Scheduled to graduate in December she excited for the next clinical rotation where she ll be exposed to the demands of another discipline such as endocrinology or pediatrics |
She wants to experience a range of disciplines before she makes a career decision but at least for now her heart seems intent on emergency care |
Working in the emergency department and seeing the role that PAs play is inspiring said Gannon |
I really love critical care |
and I like interacting with trauma patients in the inner city |
Six years in the emergency department is like years in any other department |
It has everything |
t is sometimes said that Rabbi Kook is for Israeli religious zionists what Rabbi Joseph B Soloveitchik was for modern orthodox American Jews |
To what extent was the Rav like the Rav It could be argued that Rav Kook and the Rav are the major thinkers of modern Judaism in the th century |
They tackled important ideas of Jewish nationality identity and zionism and much more then that they thought seriously about creative confrontation with secularism |
Rabbi Kook writings are sometimes esoteric and difficult to interpret |
Some of his works seem to contradict eachother |
What was the methodology of the course |
What works have students studied in class Rav Kook wrote a lot |
Some of his writing is essayist and some is exegetical |
A lot is private in diary format |
Those personal writings we have from notebooks and letters preserved by Rabbi Tzvi Yehuda Kook and the Nazir |
Rabbi David Cohen |
Because those writings were not writen for the broader public they are difficult to interpret |
Those writings presuppose that the audience has had mystical training and familiarity with topics discussed |
Thus Rav Kook is not easy to read |
A lot of the course was reading trying to figure out the meaning of a piece and its intended audience |
We mostly explored essays from when Rav Kook penned many of his boldest ideas some of which were not published within his lifetime |
One of our main area of focus were Rav Kook writings on the philosophy of halakha.In Orot HaKodesh a compilation of Rav Kook philosophical writings published by Rabbi David Cohen we explored Rav Kook approach to the nature of knowledge the nature of the world and ethics |
Here at YU we emphasize the union of Torah Umadda Jewish tradition with secular knowledge what was Rav Kook approach to Torah Umadda Rav Kook was inclined to the view that all ideas have some kernel of truth and that conflicting ideas within religion such as hassidim and misnagdim the anti hasidic movement each have their own strengths and limitations |
He approached differing philosophies the same way and it was a big part of his unique approach to secular Zionism |
Rav Kook learned to be melamed zechut to expound the positive aspects regarding the often militantly anti religious sacular Zionists |
Rav Kook notes that the may be bothered by parts of the Jewish religion that develop in galut the diaspora such as passivity and cloistering in the Bet Midrash ignoring the larger public arena |
Rav Kook learned to appreciate what they were doing in cultivating Israel as positive and view their rejection of religion as resulting from a failure to see the broader picture |
He saw their modern activism as corrective to the limited passivity of diasporic Jewish attitudes.What do you hope students gained from the course.There are several things.One is knowledge of the material.Students should know Rav Kook and not merely what people say about Rav Kook |
Next has to do with developing critical acumen.We examined to what extent were his arguments made based on assumptions about the people of his time |
In doing so students have greater understanding of the kind of issues people confronted in the th century.Last but not least learning not to be afraid to take the book in your own hands and read it On Wednesday May Yeshiva University Zahava and Moshael Straus Center for Torah and Western Thought Rabbi Arthur Schneier Program for International Affairs and Bernard Revel Graduate School of Judaic Studies in conjunction with the Mohamed Bin Zayed University for Humanities hosted a historic event bridging cultures and religious identities at the Crossroads of Civilization Museum in Dubai |
Titled Interacting Philosophies Shared Friendships the program began with opening remarks by Ahmed Obaid Al Mansoori the museum founder |
Citing the Quran teaching O mankind indeed We have created you from male and female and made you peoples and tribes that you may know one another Mansoori explained that fostering relationships with different cultures and religions is a foundational principle of the Islamic faith and that the conference was a reflection of this value |
Rabbi Stuart Halpern then offered words of greeting on behalf of both the Office of the Provost and the Straus Center |
Describing the Jewish practice of Sefirat Ha Omer the counting of days from enslavement in Egypt to Revelation at Sinai he explained that we count up to as opposed to down to one to symbolize aspiring towards greater heights while remaining faithful to our roots |
We stand here tonight he said in appreciation of the history that has come before us as we the Jewish and Islamic communities embark on a brighter future |
Following greetings from the deputy mayor of Jerusalem Fleur Hassan Nahoum Revel dean Daniel Rynhold offered the program first lecture |
Discussing Maimonides and the Parable of the Sultan Palace he offered a contextual analysis of how the parable found at the end of Maimonides major philosophical work The Guide for the Perplexed likely reflected Maimonides own balancing of his busy medical and communal work with divine contemplation |
Ibrahim Burshashen then delivered a talk in Arabic on the strong influence the Islamic philosopher Ibn Rushd had on Maimonides Guide.Burshashen colleague Haider Hussain followed with a discussion of The Role and Impact of Islamic Civilization on Jewish Philosophy A Look at the Joint Interaction with Moses Ben Maimon as an Example |
