Apr 24	comment	Orbital mechanics and rocketry: Is it ever a good idea to intentionally lower periapsis? @DeerHunter I see. so plane changes should be performed at apoapsis? That makes sense (lower delta-v at lower orbital speed to perform the same plane change)... So i'd want to adjust the position of the apoapsis to coincide with one of the rising or descending nodes? Because it's too difficult to know where or how to get that apoapsis in the right spot that ahead of time (before entering an orbit)

Apr 24	comment	Orbital mechanics and rocketry: Is it ever a good idea to intentionally lower periapsis? You're awesome, thanks!
Apr 24	comment	Orbital mechanics and rocketry: Is it ever a good idea to intentionally lower periapsis? @DeerHunter you're probably right. My background isn't in this field

Dec 2	comment	With Newton's third law, why are things capable of moving? This answer is completely awesome. My question to you is how on earth did you decide it that it was better to write in an entire warning label instead of removing the word "match"?
Jun 28	comment	Does diffraction contribute to the Black Drop effect? Right. I remember now from my class on Physics of Sound that the diffraction effect of structures depends on the pitch of the sound. I'm sure if I work out the expressions and factor in the distances the attenuation factor due to diffraction will work out to an infinitesimal quantity. This quantum effect would probably affect the measurement of light intensity there for a nanosecond.

Dec 20	comment	Calculating stress without strain Well of course you get the accept. Not gonna hold out on ya.
Dec 20	accepted	Calculating stress without strain
Dec 20	comment	Calculating stress without strain Well... I think I still need a bit more direction in the way of how to get it done though.
Dec 17	comment	Calculating stress without strain I think the actual crack geometry can be faked pretty convincingly. I'll post back with results from my code when I get it finished.

Dec 17	comment	Calculating stress without strain I'd also like to point out something I hadn't considered up to this point. Consider the L-shape again but this time it is spinning. Due to inertia alone, at some particular speed a real structure of that shape would break due to internal tensile forces. How to go about calculating something like that?
