How Einstein Came Up With Special Relativity

Time dilation. Length contraction. The fact that time moves faster at your face than it does at your feet. These are all experimentally verified consequences of the Special Theory of Relativity, proposed in 1905 by Albert Einstein. But the theory also helped explain one of the most nagging questions of modern physics, namely: how anything other than light can move. Minutephysics’ Henry Reich explains, with the help of some sliding switcheroos. [Via Henry Reich]

coburn7x: 10 g Boric acid + methanol + a couple drops of concentrated sulfuric acid in a water cooler jug… Swirled around to produce flammable boric acid trimethyl ester, B(H3CO)3. Drop a burning splint and rapid combustion + a loud whoosh noise is what you get :) It’s green because boron compounds burn with a green flame. Here is the production of the ester: B(OH)3 + 3 CH3OH —> B(H3CO)3 + 3 H2O Boric acid + methanol —> boric acid trimethyl ester + water The reason for adding concentrated sulfuric acid is to shift the equilibrium to the right toward the ester because sulfuric acid is very hygroscopic (moisture absorbing) and it removes water from the system.

Oh look, it's a ghost!
