Thereâs a lot of talk these days about âsmartâ things: smart phones, for example. But itâs not always very clear what âsmartâ really means. It sometimes seems as though it just means a phone you can use to also surf the web.In reality a smartphone is only barely a phone.mart glasses build a soundscape of the world. Meanwhile Spanish engineers have equipped a pair of sunglasses with two micro cameras and headphones in a system called EYE 21. The system makes a 3D model of the space the cameras see and represents it with sounds.
Star-Spangled Banner redirects here. For the flag that flew over Fort McHenry, see Star-Spangled Banner (flag). For the present flag, see Flag of the United States. The Star-Spangled Banner is the national anthem of the United States of America.
Here's a refresher course on the history of the âStar-Spangled Banner.â. The banner. The poet Francis Scott Key described a giant flag that flew over Fort McHenry in Baltimore. National Park Ranger Jim Bailey points to a replica of that flag that's 30 feet tall and 42 feet wide. Each of the 15 stripes is 2 feet in width, or as Francis Scott Key would write, 'very broad,' and each of the stars measure two feet from point to point, or as Key would write, 'very bright'. So the broad stripes and bright stars of the 'Star-Spangled Banner' are not a poetic exaggeration of Key.
