| Posted: 14 Aug 2016 09:29 PM PDT Hi folks, While I'm a layperson (biochemistry undergraduate student currently) I've thought of how prevalent mental disorders (seem) to be in humans. I've wondered if this is due to how complex our brains are, having to provide for rational thought, reasoning, intricate language etc. Essentially my back of the napkin theory is that our brains are so unimaginably complex, there has to be some mess ups along the way leading to mental disorders. Furthermore, I wonder if that other animals with brains not as complex as ours experience mental disorders less severely or not as often. Is there any science discussing this and the prevalence of mental disorders in relation to brain complexity? [link] [comments]  |

| What is a good metric to identify the "uniformity" of a distribution? Posted: 15 Aug 2016 06:12 AM PDT I have a distribution of temperatures over a 2-D plane. Trying different methods (and simulations) to heat the plane as uniformly as possible to a uniform temperature. Sensors (and virtual sensors in CFD) placed along various 1-D lines (rakes) record a temperature distribution. As expected the edges are cooler than the center with "waviness" across the center depending on flow conditions. But comparing distribution curves by eye for various applied conditions is not good enough, I need a single metric to that says "This temperature distribution is more uniform than that one". I'm trying the "entropy of a probability distribution" as a first shot (-Sum of p(x)ln(p(x)), just normalizing the temperature range as 0~1 and treating each regularly spaced sensor as a "bin", then whichever case has the highest entropy is the "most uniform". Is there some better metric of uniformity I can use? [link] [comments]  |

| Why does tin make a chime-like sound when cooling down? Posted: 14 Aug 2016 08:42 PM PDT This question surged right after I saw this video by the Backyard Scientist. In it, the guy tries to make an indentation on a block of dry-ice using a heated up tin ingot. Once the ingot starts to cool down, however, it starts making an amazing chiming sound, like the stuff you'd expect to hear when entering an enchanted forest or finding treasure. It's that fantastic. The Scientist assumes it's because of the tin's crystal structure sudden contraction, but I couldn't find any more information on this subject. Anyone got a better explanation? Thanks, y'all.

| Is misophonia a real condition and if so, what is the mechanism behind it? Posted: 14 Aug 2016 02:37 PM PDT Misophonia, or the condition of experiencing negative reactions to particular sounds, is not a recognized diagnosis, as far as I'm aware. But people claim to have it. There seems to be some disagreement among self-reported sufferers as to what it is, and how it works. As there's not an official diagnostic criteria, it seems open to interpretation. I couldn't find anything discussing this in askscience or any "serious" science subreddit. Is this considered by the scientific community to be a real condition, or is it an expression of some other condition(s)? [link] [comments]  |
| Can taking testosterone/hgh before fertilization affect the baby? Posted: 14 Aug 2016 01:33 PM PDT I have heard the development of babies has a lot to do with transcription factors and their gradients in the cell. Is there something protecting the gametes from the changes in the parents body? Like, can I take a much of HGH before sex and end up with a mini Arnold? Thanks. [link] [comments]  |
| Posted: 14 Aug 2016 08:38 AM PDT I've seen a lot of conflicting information on whether or not energy is conserved (or stress-energy-momentum, for that matter). Would someone be able to give an answer, or possibly pose a correction to the question so that it can be more accurately answered? [link] [comments]  |
| Posted: 14 Aug 2016 05:08 PM PDT A follow up question: is precipitation solely dependent on temperature differences? Thank you! [link] [comments]  |
| Is Dark-matter or anti-matter a real thing, or is it just science fiction? Posted: 14 Aug 2016 11:55 AM PDT The title says it all. You hear these words thrown around a lot in doctor who, star trek, etc., but these are fictional. Is the concept of dark matter and anti-matter based in reality, are the elements themselves proven real, or is it all fake? [link] [comments]  |

| How did we discover the limits of Earth's atmosphere, and when? Posted: 14 Aug 2016 04:34 PM PDT Before we started sending rockets into space, or flying rocket planes high into the atmosphere, did we know what was beyond Earth's atmosphere? If so, how? Did early rocket scientists know what would happen past the edge of the atmosphere, or if the edge was even there? Did we know space was a vacuum? [link] [comments]  |
| Posted: 14 Aug 2016 03:02 PM PDT For example, do factors switch them on and off like light switches or are they more like dials that can be expressed in multiple degrees? [link] [comments]  |

| Posted: 14 Aug 2016 05:58 PM PDT This might be a simple question, but when you're making so many of these batteries as quickly as you are, how can you guarantee there's no chance they will short circuit? [link] [comments]  |
| How do we know that there is asymmetry between matter and antimatter in the universe? Posted: 14 Aug 2016 10:12 AM PDT It seems clear that there is much more matter locally, but when examining far off galaxies, how do we know that it is composed of matter and not antimatter? Since antimatter should yield identical spectroscopic results so I don't see how one can tell what far off systems are composed of. [link] [comments]  |
