ohc49 | What actually is going on as electrons move through a circuit? | I'm trying to understand the physical details of current more thoroughly. Let's consider a simple example with a battery and a resistor. Electrons are "flowing" from - to +.
But what does that mean? Are the excess electrons at the negative terminal leaving that terminal? If so, how do they propagate through the wire? ... | askscience | http://www.reddit.com/r/askscience/comments/ohc49/what_actually_is_going_on_as_electrons_move/ | {

mqh35 | why can't leaded engines use unleaded petrol? | I've asked this question for years, and I have gotten two different answers for it. One is that the lead lubricates the cylinder walls, and the other is that the lead reduces the temperature of the burn, allowing the engine to run cooler. Is either of these correct, or is there a different answer? | explainlikeimfive | http://www.reddit.com/r/explainlikeimfive/comments/mqh35/why_cant_leaded_engines_use_unleaded_petrol/ | {

j9msq | From where do we measure distances between celestial bodies? (center-to-center? surface-to-surface?) | Essentially exactly what's in the title. For example if you're saying the earth is on average 1 AU from the sun, then does that mean that the center of the earth is 1 AU from the center of the sun (kind of what I figure) or that the surface of the earth is 1 AU from the surface of the sun.
