| If you put a red hot bar of iron in space with nothing around it, would it cool down? Posted: 25 Jan 2018 07:42 PM PST Since it has nothing to transfer the energy to, would it stay hot indefinitely? [link] [comments]  |

| Does whether you're sleeping or awake have an affect on how long medication lasts? Posted: 25 Jan 2018 06:38 AM PST I know that metabolism slows down (like 10%) and that digestion does too when you're asleep, but does that mean that medicine either lasts longer or takes longer to kick in? Or is it effective for the normal amount of time stated on the bottle? [link] [comments]  |
| Posted: 25 Jan 2018 09:57 AM PST Given that the electricity from a car socket comes from burning fuel to the alternator, how much am I paying per mWh? Is the price comparable to what I'm paying for at home? Are there any places where the price of mains electricity is so high that charging batteries in the car is actually cheaper?

| How does the electric field in a pn junction work? Posted: 26 Jan 2018 01:34 AM PST I need to know the basic principle of pn junctions for my electronics class, I don't have good up to date knowledge about orbitals valence bands n'stuff. I had that in an unrelated class 4 years back and never repeated it. I get that electrons from the N-type material recombine with the holes in the P-type material to create a depleted zone where no holes or electrons are present. Then how is it that this very zone pushes the remaining electrons and holes away from it? Or is there like a continuous stream going towards each other at any point in time and cancelling each other out? Ive read that the electric field points from the n-type towards the p-type, but wouldnt that just make it easier for the electrons in the n-type to be accelerated towards the p-type material? I think I most likely have some misconceptions here. Cheers. [link] [comments]  |

| How are the quantum mechanical laws of physics scaled to or related Basic Newtonian Physics? Posted: 25 Jan 2018 07:01 PM PST The two seem so radically different from each-other (superposition vs F=ma etc). How are they related to one another other than just differences in scale? I read an excerpt from one of Richard Feynman's books where (if I understood it correctly) he said that the quantum mechanical laws are the same as Newtonian Physics, it's just that Newtonian Physics is an average of the billions of interactions at the quantum level, scaled up to the macro level. Did I understand that correctly? I doubt Feynman would be wrong about something like that. [link] [comments]  |
| Is 1000 calories of ice cream the same as 1000 calories in apples? Posted: 25 Jan 2018 10:12 AM PST For example if I was on a CICO diet and I'm restricting to 1000 calories, would I still lose the same amount of weight if I ate unhealthy foods than if I ate healthy foods? [link] [comments]  |
| Posted: 25 Jan 2018 06:27 PM PST I am in a research group and this is a question we began discussing. I just don't know much about cosmic rays and their ability to affect or develop electricity. Edit: I should mention that our device will be sent into the upper stratosphere on a balloon payload. [link] [comments]  |
