The title of this week’s Cosmos, “The Electric Boy,” isn’t a Spielberg movie. It just sounds like one. Our electric boy is Michael Faraday (1791-1867), who puzzled out electricity and magnetism. Without his discoveries, says Tyson, we might not be using electricity, watching TV and computing. Blame Faraday for Twitter and
The coolest thing about magnetism is that it's a relativistic effect, the only one that you see every day. Currents in a wire produce magnetic fields, which exert a force on moving charges outside the wire. But what if you look at things from the electron's point of view? No current, therefore no magnetic field, and yet the "moving charge" still moves. It's the coolest thing I get to teach. No lie.
IK,R? I had been teaching college physics about eight years when I first had to teach E&M (out of Purcell) and saw it for the first time. Same reaction.
The people in the outpost could request help by means of electromagnetic waves (radio). If we could have arranged for a plane to get to Benghazi from Italy at the same speed as the electromagnetic waves were travelling, the Jihadis could have been thwarted.
Outside of my specialty, so I just looked it up at <a href="http:\/\/www.urbandictionary.com\/define.php\?term=peeballs" target="_blank">urbandictionary</a>.

No love? Hell, a share an inertial reference frame with those little buggers.

according to Bing and Bob anyways
Do Androids Dream of Electric Dildos?
If only we had MOIP (Marines over IP).
For some value of &quot;would have to&quot;.
If Tyson could <i>explain</i> dark energy, he wouldn&#039;t have to be on the cheesy Fox Network.
Can you libel something that doesn&#039;t exist?
