Bismuth crystals exhibit iridescence?!
Oh hi there, my new favourite chemical element ;D
Although, social sacrifices are not entirely necessary to pursue your first love (science that is). ;D
128(980e)^1/2 is 6606.481884… in case anyone was wondering.

Gallium
Gallium literally melts in your hand. It’s soft, glass-like, silvery, and has a melting point of 29.76 degrees Celsius—which is just above room temperature, so it will pool in your hand like liquid silver. As a solid, Gallium is brittle and an even poorer electrical conductor than lead. It’s mainly used in microelectronics, medical thermometers, in semiconductor production for laser diodes and solar panels, and it also makes brilliant mirrors—but elemental Gallium doesn’t exist in nature. It’s just a byproduct of aluminium and zinc, so don’t go out panning for it.
You probably already know how to sharpen pencils but what do you do when you have say, 5000 each hour? This hypnotic animation shows the way of the factory ;D Little note though, all the new pencils I seem to buy are round bottom and require you to sharpen them! :(
I don’t mean to boast but I’ve been suspicious for a while that it isn’t actually magic ;D
Bill Gates being cheeky ;)
Classic.
Don’t usually appreciate wishy-washy motivational images… but this uses simultaneous equations to eliminate love as a variable of life!! :o
