Philadelphia decides that bloggers must pay $300 for a "license." Again, government, this time at a city level, interprets "shall make no law" as "hey, boys, let's make a law!" The first — and the fourteenth — amendment specifically say this is not allowable government behavior.

So you think of electrons like dominoes in a wire. Push on the one in the end, the others react one after another. Pretty vanilla physics. Further, because the electrons are moving, you get magnetic effects, radio, etc. Good stuff. So. What if you move all the "dominos" at once? Put your virtual hand on all of them, and push them over. They're not moving sequentially any longer. They move together. At any speed you can make them go. Well, that's what these researchers are doing — "pushing" all along a conductor at once, able to make a signal go — ready? — FTL. Fascinating stuff. And it may explain pulsars.
