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.

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.
In a variety of forms, on the battlefield and the home front, the flag expressed ideas about what it meant to be American during a time of war. It symbolized the ideals the nation was fighting for, and it called on Americans to support those ideals through service and sacrifice. This virtual gallery features a selection of Museum objects that illustrate the use and meaning of the flag in World War II. Curators are researching these and other objects for a new exhibition that will accompany the original Star-Spangled Banner, For Which It Stands: The American Flag in American Life.
