The Inglorious Legacy of the 'Iron Curtain' in 20 Maps

Having their troops and secret agents infiltrated through half of Europe all the way to Germany, the Soviet Union as a matter of convenience decided to keep control of all of these regions it had "liberated" during the war.

How to slow down light until it stops

In vacuum, light always travels at a constant speed of 299,792,458 metres per second. Nothing can travel faster than this constant c, as denoted by physicists. These two postulates are basic building blocks of modern physics and were first announced more than a hundred years ago by Albert Einstein. Yet, there are ingenious ways to slow light to the point of trapping it in a dead stop. Prepare for some weirdness.
