comment Why there is a 1/2 in kinetic energy formula?
that's what helped me understand the formula: the mantra, it's been integrated, it's been integrated, it's been integrated, every time i look at a body in movement.

comment Why there is a 1/2 in kinetic energy formula?
the derivation of the formula is complicated, and i think the simplest explanation requires at least calculus and linear algebra. en.wikipedia.org/wiki/Kinetic_energy#Derivation (or you could try reading newton's principia, but good luck.) that's why the formula exists -- so that you can just plug variables into it without having to worry about deriving it! personally, i think of it as similar to the difference between a compiled program and program source code.

comment How does uranium from supernovae explosions end up in mineral veins in a planet?
you beat me to asking it, but roughly this question came to mind as i was lying in bed with my wife, and intuitively i reached this same conclusion. at that point, in bed, relaxed, it seemed extremely unlikely to me somehow that astro-snowballed uranium would just end up just so in planetary crust, due to the large number of collisions that would be required over time to 'snowball' large amounts of helium and hydrogen together into uranium and all the way into planetary crust in the backwaters of the universe, the local group, no less, just in time for it to keep decaying radioactively...
