Thank you all for your replies. In the near term, I'll likely take Enigma's advice and take a few classes to freshen up with. Regardless where the future takes me, I could use the freshening. Beyond that, I guess I still have some soul searching to do. :-)

I don't quite understand why the sun is so completely made of hydrogen and helium, with only roughly 0.15% other elements. I assume that the composition of the "cloud" that ultimately formed the solar system was fairly homogeneous. I also get, from the above article, how proximity to the...

Perhaps that is really the problem. Having finally talked myself into going back to school, I'm a little dazed at the possibilities, and haven't completely settled on what I'd ultimately like to go do every day. So many wonderful choices.

By way of clarification, I'm not entirely crazy. I know I'm not currently qualified to enter an aerospace doctoral program. I'm not sure what I'm missing to be able to enter a master's program. These are ultimate goals, far away though they may be.

Hi All, I very much want to become part of the growing off-world industry. Companies like those dreaming of asteroid mining really pique my interests. In particular, I'd like to be involved with design and implementation of robotic systems. I have an MSEE, and though I've been...

True. "Intuitive" was a poor choice of words. I suppose what I really desire is just some intellectual comfort with what a wave function is. Energy? Matter? Dark magic? An extremely surprising new structural form of carbon? I don't doubt my ability to understand the mathematics of the wave...

Well, heck, if my understanding of quantum mechanics has caught up to Einstein, I shouldn't feel too badly! :-) So the wavefunction really exists. Particles really are smeared, and in several places at once. They look like they are in one place when we observe them, but only because our...

So, tell me if I understand... A particle, when left alone, does exist, and has a specific position, charge, and momentum at each instantaneous moment in time. Because of uncertainty (our inability to measure it without interfering with it) we can't know these all at once, so describe the...
