| Posted: 18 Oct 2016 05:47 AM PDT So what usually happens to me is that I arrive home from school, and usually have a two hour nap. Lets say from 5pm - 7pm. Then I stay up until 12am and wake up at 6am. Is there a difference if I stay up until 10pm and sleep till 6am? Does anything happen in brain function? [link] [comments]  |

| Posted: 17 Oct 2016 09:36 AM PDT My kids have lived their whole lives in a colder climate than I grew up in, and they seem to be more tolerant of cold, and less tolerant of heat. So when my kids are going around shirtless when the temperature is in the high 50s F, have their bodies "learned" to handle that situation differently than mine does? Or have my kids just learned to deal with it mentally? Side question: I also have some friends who grew up in a warm climate, but who are decidedly "cold-weather people". Is that a physiological thing too? Do people's bodies have different equilibria that they regulate toward, with different levels of efficiency? Or is it psychological? [link] [comments]  |
| In theory how much more energy can we get from fusion than from fission? Posted: 18 Oct 2016 05:48 AM PDT For example if we take 1 gram of U-235 and calculate maximum theoretic energy we can get from fission of that 1 gram and then take 1 gram of hydrogen isotopes and calculate maximum theoretic energy we get from its fusion.

| Posted: 17 Oct 2016 08:28 PM PDT We can make real, physical mass-spring-damper systems that are modeled by mx''+cx'+kx=0, because springs, dampers, and mass are all real things that have a linear relationship between their respective derivatives of position and force. Can we go higher? Is there some device such that I can make a real, physical system modeled by px'''+mx''+cx'+kx=0, where p is some constant physically analogous to m, c and k? What about even higher derivatives? [link] [comments]  |

| Fourier Transform Infrared Spectroscopy (FTIR) What's the difference? Posted: 17 Oct 2016 09:04 PM PDT Hi AskScience, I'm working on a project involving FT-IR and I've hit a wall in explaining how it works. I understand the basics of how infrared excitation and resonance frequencies will allow you to infer what molecules are present in a sample. However, I'm not sure how the Fourier Transform function applies to this technique. It's my understanding that the function is the reason why we can see the peaks/valleys of the graph in the first place, but I have trouble really understanding the details of what's happening. Can anyone explain what a specrograph would look like if no Fourier Transform function was applied? I've never used a non-Fourier Transform Infrared Spectrometer, so it's hard to truly explain and appreciate how far the technology has progressed. P.S. My background is in biology, but I will try my best to understand the chemical/physical aspects of any explanations :) [link] [comments]  |
| Is hearing sensitivity linked to a creature's size in any way? Posted: 17 Oct 2016 08:27 PM PDT Example (and I know this is science fiction, but that's why I'm asking), in the Monsters V.S. Aliens movie, Susan can talk with the other characters despite her ears being 15 meters (49 feet) away from them, and they're talking at a regular volume. Presumably this is because her ears/eardrums are larger and can pick up fainter sounds. Does this also apply in real life? Say, do lions have better hearing ability than a house cat does?

| Does constant exposure to a certain colour affect your mind at all? Posted: 17 Oct 2016 05:46 PM PDT So I've heard from random sites that the colour red can promote caution or even anxiety. Is this true at all? [link] [comments]  |
| Do photons still move at C inside the event horizon, are they still photons inside the singularity? Posted: 17 Oct 2016 02:56 PM PDT |
| Why do lasers have such a visible diffraction pattern? Posted: 18 Oct 2016 01:05 AM PDT When looking at a laser hitting a surface, whats the cause of the obvious diffusion pattern from it? Its almost like being able to see each individual photon beam. [link] [comments]  |
| Can you combine mass energy equivalence and Sine, Tangent and Cosine Law? Posted: 18 Oct 2016 04:39 AM PDT If Mass energy equivalence works like a right angled triangle. What happens when you apply sine law, cosine law and tangent law to it? And how would that math be applied in reality? [link] [comments]  |

| What materials are radiolucent in x-ray machines? Posted: 17 Oct 2016 08:20 PM PDT I've check many search engines, but none have different answers and say "skin is radiolucent and bone isn't." [link] [comments]  |
| Do molecules in real life exist in a combination of all the resonance forms of that molecule? Posted: 17 Oct 2016 07:45 PM PDT A little confused right now. I thought resonance forms where what the molecule can switch between, sort of like equal combinations of that molecule. I was just led to believe that all resonance forms are inaccurate and it's actually an amalgamation of all them that correctly model what a molecule actually looks like. [link] [comments]  |
| Why can't we test for neurotransmitter levels in the body? Posted: 17 Oct 2016 06:21 PM PDT It seems as though we have tests available for so many other things in the body. Why can't we measure levels of neurotransmitters? This could be used to determine which antidepressant might be most effective, for example. [link] [comments]  |

| Correlation Between Element Density and Rarity? Posted: 17 Oct 2016 05:40 PM PDT So if all of the elements denser than iron are made in the final moments of massive supernovae, and the denser elements are the most difficult to make and thus produced in progressively smaller amounts, shouldn't the rarity of an element directly follow its density? Do they? Lead seems fairly common. Is that just because of Earth's specific accretion? [link] [comments]  |
