| Is it possible to sneeze during sleep? Posted: 14 Dec 2015 09:35 PM PST Do you just wake up and sneeze and then right after fall back to sleep, or do you sneeze while sleeping or is it simply not doable? [link] [10 comments]  |
| Just started reading the Martian, could the thin atmosphere actually make a duststorm? Posted: 15 Dec 2015 03:02 AM PST It seems like the author goes out of his way to be technical and precise, but then notes that there's a 1% atmosphere. Could that actually lift martian dust up? Also, at the beginning, Mark Watley is injured in a 175 km/hr dust storm - what would that feel like? Is any of that part realistic? [link] [8 comments]  |
| What do we know about how the brain stores memories? Posted: 14 Dec 2015 03:55 PM PST I know that there is a lot that we don't know about this but, what is known about the brain and the way it deals with memory? [link] [13 comments]  |

| What is cuteness aggression and what purpose does it serve? Posted: 14 Dec 2015 02:47 PM PST I'm a 6'3" broad shouldered college student and want to know why every time I see a picture of a kitten on Reddit I want to punch a hole through my wall. [link] [7 comments]  |
| Physics noob: What happens to the suns heat after it hits the earth? Posted: 15 Dec 2015 12:14 AM PST Here is my very noobish and probably wrong understanding of the physics of heat on Earth. Sun sends rays, rays warm up planet, get stored in plants, animals eat plants, energy becomes kinetic as animals and people move, that energy then becomes heat, then becomes radiation. Is that correct? If it is (which I'm probably guessing it isn't, I'm probably missing something) then the sun has been shining down on earth for billions of years, what happens to all that radiation? Is it why we have lightning? (probably not but again, I'm really trying to grasp this) Thanks! Please be nice. 'Physics' [link] [1 comment]  |

| Is it possible for humans to build an artificial continent? Posted: 14 Dec 2015 05:42 PM PST Let's say overpopulation gets to a point where the situation is no longer maintainable. Could humans build a giant artificial continent in the middle of the Pacific ocean to help alleviate the crowding? [link] [2 comments]  |
| Posted: 14 Dec 2015 10:59 AM PST I presume shininess isn't unique to metals and metals themselves may vary in how shiny they are. But metals have unique properties that make them, well, metals (conductivity, malleability, etc). I can understand conductivity is related to how the electrons are arranged, malleability is also probably related to this. But why the fairly commonplace shininess? Is it also the electro chemical properties of the metal that make it shiny or is it something else? And if so, why? [link] [11 comments]  |

| Magnetic fields in lorentz transformation? Posted: 14 Dec 2015 08:22 AM PST Hi, First of all magnetic fields always seemed counterintuitive to me and i hope to change this a little. I read that the magnetic field is just the transformation of the electric field to a moving observer, but is this observer stationary to the moving charge or to the movement of the field (=c) ? I mean let's take a straight wire with a current inside and a stationary electric charge close to the wire. My knowlegde says they shouldn't influence each other. But there certainly is an observer that sees both of the charge as current flowing in some direction and so they should influence each other via lorenz force. And how about induction? Can it be derived from any static electric effect with the transformation? God i hate being taught laws but not where they come from. [link] [2 comments]  |

| What the heck is going on with this warm weather all autumn/winter? Posted: 14 Dec 2015 12:37 PM PST I'm in school in the Albany, NY area and usually around early-mid October I can't go outside without a sweatshirt or risk immediate hypothermia. Today, I went to do some errands and I was walking around comfortably in a no-sleeve shirt and shorts. What's the deal? Is this the direct result of global warming, a lesser effect, an El Nino/Nina?

| Why would chronic hyperinsulinemia induce hunger? Posted: 14 Dec 2015 03:11 PM PST Acutely, the release of insulin is associated with satiety. However, I have come across a number of papers that associate hyperinsulinemia with chronic hunger. I'm having trouble thinking of a mechanism for this. Anyone have any insight?

| Posted: 14 Dec 2015 08:49 AM PST Neon is something like the 5th most abundant element in the Universe, and yet it makes up a tiny amount of our atmosphere and crust. It's non-reactive, so I can see why it wouldn't form any compounds in the crust, but I don't see why it would be so rare in the atmosphere. It's more abundant by mass than nitrogen in the Solar System, and yet in our atmosphere, there's about 40000 times more nitrogen than there is neon. There's even more argon than there is neon, even though the two are chemically similar and neon is way more abundant in general. What gives? [link] [2 comments]  |
