The chick in the video is hot.

Ahem, women wear contacts. You know, to keep the “self-torque” problem discreet.

If only you could cross two posts and they came out as one...

"Don’t cross the streams.

And never, NEVER, pee on the third rail!

Important safety tip. Thanks, Egon.

Oliver Heaviside:
A self-taught mathematician, admitted mama’s boy who lived with his mom. He is known for taking James Clerk Maxwells 200 field equations with Josiah Willard and calling them “abominations”, discarded all but four which he transformed into vector equations, thus giving us all we know about the entire electromagnetic spectrum.

Only Nicola Tesla tried to make sense of some of the rest of Maxwell’s field equations - among them, his attempt to create a broadcast power station. And his invention of alternating current (transmitted power) - Edison only discovered direct current (stored power).

Without Maxwell, Tesla would have been just another mad scientist of the period, and Einstein would have been a postal clerk or a comedian, assuming he fled Germany in the first place.

I’m with you - but I think the gist is that light is neat and does weird things if you play with it.

[GingisK]

Wow! That is very interesting. Thank you for posting that article. It seems that we really don’t know squat.

[GingisK]

I remember someone in physics class singing, “Dr. Maxwell and his 200 equations made sure that I was dead, ding ding”.

[Nifster]

Nice played

From the article: More recently, researchers have found that light can also be twisted, a property called angular momentum.

Hm - recently - this article is from 1940: On the current and the density of the electric charge, the energy, the linear momentum and the angular momentum of arbitrary fields
