most of the undergrad cs classes i took at berkeley were somewhat open. In the lower div classes, you would usually get unlimited notes, and the upper div classes would usually give you only a few pages (usually 2 to 4). it seemed to be a g

I have to be missing something here. Isn't it obvious that any discrete, single use, path location traversal can be transformed into the tsp by making every point on the path a node connected to it's nearest neighbors? Is the newsworthy poi

don't get me wrong, i agree that there's tons of flaws with capitalism, but i was curious as to why the natural emergence of cartels is considered a flaw.

would you mind expanding on why you think this result means capitalism is flawed?

slaves aren't paid, though, and these workers are. for me, the saddest thing about those conditions isn't that workers have to endure them, but that they voluntarily endure them. whether it's because either the pay is high enough or the jo

if you want to switch analogies to rape, fine, but i think that's a much worse analogy to use. blame isn't a zero-sum game. if a hypothetical human walks down the street in provocative or revealing clothing in a bad part of town without any

it's not. the issue (for me) is how valuable the valuables are and how much security is protecting the valuables. There's a good reason why there's a major difference between the security protecting the mona lisa and the security protecting

I didn't say it was easy; it's usually pretty hard/expensive to do it right. But there are known best practices, and it looks like those weren't followed (at the very least, have a good password policy and salt the goddammed passwords befor

seems i forgot to multiply by 1.6. whoops. pluto-charon (imo) is a dual dwarf-planet system not planet and moon. Sun Jupiter is my argument for why a planet shouldn't be defined only by barycenter location. updated density: 13.55g/cc. this

by joshAg 15y ago
nope, not at all. the event horizon (schwarzschild radius) of the sun is 3km. i don't think planethood should be defined based on whether the barycenter of the system is within the orbited object, but I do think that's a pretty good definit

there's a major error in their calculation in that they didn't do that in 3 dimensions, and they assumed that all planets always lie on the same radius from the sun. do the math again with jupiter and saturn on opposite sides and use 3 dime

Jupiter has an orbital velocity of only 13.7 km/s, so even if Io is going the right direction and all the elliptical planes are parallel, isn't that still just a max orbital velocity of ~40 km/s, which is slow enough for orbit at 1AU? It'd

by joshAg 15y ago
the orbit of a satellite does not depend on the mass of the satellite. the period and orbital velocity are dependent on the mass of the orbited object and the radius of the orbit.

what's the difference between rock and ice? is there a boundary where if the melting point is below a certain value then the substance is ice, and if it's above that value it's rock? it's not like rock can't melt in the right circumstances.

If Jupiter were to orbit the sun at the same distance of the earth, what would happen to the orbits of the moons if its mass suddenly disappeared? Would they still be cometary (at the least) or would they settle into a planetary orbit?

by joshAg 15y ago
i believe the center of mass is inside the sun if you look at each planet-sun pair individually. IOW, 2 body to n-body kind of messes this definition up. also, by inside the sun do you mean inside the corona?

by joshAg 15y ago
I believe the center of mass for the earth moon system is something like 3000 km from the center of the earth (in a moonward direction). Just for reference, the radius of the earth is 6300 km. The density of the earth is ~5.52g/cc, and halv

the orbital period of the satellite isn't as important as the orbital velocity of the planet around the sun. the earth goes around the sun at 29 785.8944 mps, so for a satellite to appear to stand still (from the sun's perspective) it needs
627.
by joshAg 15y ago
Isn't that true for all moons, though, simply because the radius of the orbit around the sun is much larger than the radius of the moon around the planet? also, isn't the force ratio issue more an issue of the inverse square law than anythi
