Interesting Facts

There is no such thing as bullet proof glass. (In spite of what movies and TV show us, no glass is completely bullet proof, the most it can claim is to be bullet resistant. Of course some manufacturers still use the term bullet proof, I guess because it sells, some even call this kind of glass, bullet proof resistant glass, which, if you think about it, is a complete contradiction in terms.)

A timely invention has been announced in Germany, a car windscreen that doesn't allow ice to form on it. (Developed at the Fraunhofer Institute for Surface Technology (IST) in Braunschweig, in north-central Germany, the windscreen prevents ice forming even at temperatures as low as minus 18° C. There's only one problem, the thin coating of indium tin oxide applied to the window, can interfere with radio and mobile phone reception. I wonder what everyone will do with those extra minutes on a frosty morning?)

If you wore a pair of glasses that made what you see appear up-side-down, after about six months your brain would work-out what was wrong and would adjust your vision to turn it the right way up. But upon taking the glasses off again the world would appear up-side-down, and again it would take about six months for your brain to rectify itself. (Who discovered this? And why?)
