High School Acceleration of space craft in space?
Now here is MY question, and I'll be coming back to check on it, so use your man-head: What if one was in deep space (super low density, just a few sparse hydrogen particles mainly), in a ship of course, and wanted to accelerate with very little pre-existing momentum? I guess my question is... -

High School Acceleration of space craft in space?
I'm surprised no one has mentioned that space is not a vacuum and that friction: - caused by the energy exchange between object 1, the spaceship, and objects n -- small particles in space, viz. by the transfer of momentum between the two variables would cause the ship to slowly decrease in... -

Learning device, help me expound: on Faraday's choice of ion , and unionized
Oh yeah, and this could be really dumb. Oh well, in order to have good ideas, you have to give the potentially bad ones a voice too- ddd1600

Learning device, help me expound: on Faraday's choice of ion , and unionized
Learning device, help me expound: on Faraday's choice of "ion", and "unionized" So I was writing down some notes to myself on electrochemistry (100 level college chemistry---elementary electrochemistry chapter) and I wrote down the word "unionized" (as in, 'un-ionized') and realized that there...- ddd1600

What's the difference between an electron hole and a positron?
Indeed, that's more than good enough for government work, thanks.- ddd1600

What's the difference between an electron hole and a positron?
Oh, so the positive charge would be a field-type existence which originates in the protons of the conducting metal or metalloid?- ddd1600

What's the difference between an electron hole and a positron?
Seeing that electron holes "flow" in the opposite direction of the electron current in a wire, its basically just a "flowing" of the absence of electrons? What is the point of even creating an abstraction to explain something like that? I know this is how it goes in physics, but why on Earth...- ddd1600

What's the difference between an electron hole and a positron?
Qualitatively speaking, an 'electron hole' and a positron sound quite similar. Are they they same? If they are, why are different terms used and what is the utility of that, and if they aren't the same, am I completely wrong in assuming that they are in some way analogous? What kind of tree am I...- ddd1600
