how to solve a physics problem: smbc-comics.com/comic/2013-06-

thinking about potential long term projects after i get classical mechanics/ relativity / classical electromagnetism / basic (and i mean >>BASIC<<) quantum physics down

leaning towards a solar system mathematical model, then, if i'm feeling brave enough, modelling the solar wind (if someone hasn't already done it) and then making a thingy to let you plot trajectories with a solar sail (letting you vary parameters about the vessel)
this would also look cool on my resume but it'd RLY hard to make

has anyone done any research into if people get dizzy if they're living on a spinning space habitat (for centripetal gravity)? i can't imagine watching the stars/sun/planets wheeling around you constantly would be great for motion sickness

also, if you ever want to blockade a planet with a magnetic field, if you set off a nuke in the radiation belts you can essentially barricade it to any living organism while the surface stays safe

i'm really interested in the idea of radiation shielding, although i've got no idea how you'd do it in any sort of mass-conservative way (since if you want to travel long distances in space it helps to have a lightweight ship)

you can surround the ship with water or lead but they're both super heavy

another interesting thing about solar sails is that you can actually use magnets to make them go faster

part of the sailthrust comes from radiation pressure, the force exerted by light upon the sail, but part of it comes from the charged particles in the solar wind

if you pull those particles with a magnetic field towards the sail, you can get a boost
it sounds like sitting on a boat and blowing into the sail to go fast, but because you're only redirecting the momentum you can get away with it

update: as i've typed it out, i've realised this doesn't make sense. nevermind!!!

thinking about the heisenberg uncertainty principle (as you measure position of a quanta more accurately, you measure its momentum less accurately and vice versa) and quantum tunnelling

when a particle tunnels through a potential barrier it's sort of like, if it's metaphorically being measured infinity times a second, some of those measurements have maxed out momentum, giving it enough energy to overcome it

idk
still learning this stuff
to be continued i guess
