ITT: /sci/ solves my intense fear of the dark

So, thoughts on this? Is it actually a viable thing to study or is it like a "social science".

How is a cell able to manufacture proteins? It's hard to imagine molecular-scale machinery that's able to separate elements then recombine them based on instructions from DNA.

skelletins are very spooky

Quantum mechanics so far seems to have only two solid rules:
>various properties, such as energy, have no net change
>communication must go forwards in time and be no faster than light
It doesn't say how various properties must be conserved though; and so particles are constantly created, destroyed, and transmuted.

But what strikes me as odd is that events cannot simply create any particle that causes the net change of various properties to be zero.

For example, an electron can't split into two half-mass, half-charge electrons; and particles can't arbitrarily change their mass and charge by shedding a particle with properties opposite to the change.

e.g. a down quark can lose an electron and become an up quark, but it can't emit a particle with a third of the mass and charge of an electron to become a neutral quark.
Where does nature get its library of particles from?

/sci/ I wanna be a fuckin astronaut, which school should I go to to accomplish this? Is aerospace engineering the best major to take for helping this pipe dream? I'm also open to joining the Air Force.

If an equation to solve a three-body problem exists, I highly doubt that it's more than a few dozen symbols in complexity; how hard would that be to brute force?
