| Do endothermic organisms have higher entropy or greater entropy production than ectotherms? Posted: 18 Oct 2016 09:36 PM PDT I've studied endothermy and ectothermy but I have never seen this topic contextualized in terms of physical entropy, and a preliminary literature search returns no results. I suppose this question is quite interdisciplinary...maybe if I finish What Is Life? Schrödinger will tell me, but I figured I would ask the panel and see if anyone has anything insightful to say.

| Why can't nuclear half life decay be sped up with heat? Posted: 18 Oct 2016 07:38 PM PDT If you add energy to a reaction normally it quickens so why doesn't that apply to nuclear decay? [link] [comments]  |
| Posted: 18 Oct 2016 09:47 PM PDT What is the nomenclature system that includes abbreviations? What are they and where/how do you reference it? In looking through actual chemistry documents and trying to reproduce lab experiments I keep coming across two possibly archaic nomenclature systems. One is just totally random English language abbreviations like THF for tetrahydrofuran (which is fine if the name and its abbreviation are still in use but that is not always the case) and the other is partial formulas that include abbreviations or truncation of names of chemical groups as the example in the title (Et for Ethyl group). The wikipedia page for ethyl group just says "very often abbreviated Et" with no explanation or further reference (i.e. what freaking nomenclature that comes from). I ask because they seem relatively consistent for coming from different labs (i.e. I've never seen Eth2O or something, so it's not improvised notation) but a lot of this is not used anymore and therefore difficult to reference online. Incidentally when did everyone suddenly become sane and start using fairly consistent naming usually providing at least 2? Also here is the title formatted with sub reddit style (I don't normally use it because headlines are white on white in night mode): What notation or nomenclature system gives us chemical formulas that look like Et20 instead of C4H10O or (C2H5)2O (Diethyl Ether)[link] [comments]  |
| How is a particle's spin measured? Posted: 18 Oct 2016 05:00 PM PDT I get how charged particles can be measured magnetically, but what about neutral ones? [link] [comments]  |
| Posted: 18 Oct 2016 03:35 PM PDT In other words, I know that a moving electric charge produces a magnetic field. So assuming there was a lone electron flying through empty space and I could match speeds with it and observe it while travelling parallel to it. Since, from my frame of reference, neither of us are moving, is it generating a magnetic field? If not? Intuitively I would think someone traveling slightly slower WOULD observe a magnetic field. I know this is somehow deeply tied to the questions which sparked Special Relativity, I can never find a good answer as to WHY though. It's been bugging me since I first started learning about Maxwell's Equations. Thanks! [link] [comments]  |
| Why does certain foods stain your skin with its smell? Posted: 18 Oct 2016 04:44 PM PDT I've noticed that some foods (such as: garlic, onion, oranges, etc) stain your skin with an either pleasant or disgusting smell even after you washed your hands several times. My first guess would be that it depends on the pH level of each food, but I'm not really sure. Why does this happen? [link] [comments]  |

| Do molecules that are polar, but do not contain a metal ion, have some degree of magnetism? Posted: 18 Oct 2016 05:35 PM PDT Specifically polar-covalent molecules, wondering if they are affected in some way by a magnet or something of the like. [link] [comments]  |

| What was the geological aftermath when the Twin Towers fell? Posted: 18 Oct 2016 08:41 AM PDT (x-post from /r/morbidquestions) A few days ago there was TIL post that while re-excavating Ground Zero they found a shipwreck from the 1700's, uncovered in part by the damaged ground from the fall. It occured to me - Manhatten's an island. Partially man-made. The Twin Towers were at the time, the largest buildings on the planet. So what kind of geologic result occurred from almost two billion pounds of weight slamming into the earth at full speed? That much force had to have set off Richter scales in the surrounding region at the very least. [link] [comments]  |
| Which languages can we say are least evolved from their ancestral forms? Posted: 18 Oct 2016 09:19 AM PDT I understand that languages evolve over time. I do not know whether languages all evolve at the same rate over time, or if sometimes languages or dialects will go through bursts of change or periods of long stability. If sometimes one language will evolve faster than another, can we say that some languages are very much like their ancestral forms and others are very changed? And if so, what languages do we know of are very much unchanged? Like to make an analogy, a modern coelacanth and a human are both lobe-finned fishes that share a common lobe-finned fish ancestor, but the modern coelacanth looks almost indistinguishable from that ancestor and humans look quite different by comparison.

| Why can a baby live on milk only, but not an adult? Posted: 18 Oct 2016 07:42 AM PDT What do adults need that babies don't? Or would it technically be possible for an adult to live on milk alone? [link] [comments]  |
| Posted: 18 Oct 2016 06:19 AM PDT Yesterday a psychiatrist told me that I might need an electrical brain stimulation because some of my dendrites and axons were glued together and electricity would unglue them. Is that true? How can electricity unglue them? [link] [comments]  |
| How does conductivity in metallic glasses work? Posted: 18 Oct 2016 12:14 PM PDT In crystals we have the Bloch waves which lead to the band structure, which then explains conductivity, but Bloch waves need translational periodicity. We obviously dont have that in metallic glasses. So how does electric conductivity work? And is there a (well defined) band structure for electrons in metallic glasses? [link] [comments]  |
| How to calculate the area of a circle in curved space? Posted: 18 Oct 2016 09:16 AM PDT Is there a general form to describe how to calculate the area of a circle in curved space? For example, this link describes the area of a circle covering a hemisphere and gives the formula Area = (8/π) * Radius2 (where radius is the one inscribed on the sphere rather than the radius of the sphere). We can also assume that for a small radius of circle / radius of sphere the curvature of space is less relevant and the formula will look more like the flat space one: Area ~ π * Radius2 So the question I ask, is there a general formula to describe the area of of this circle for any radius that exists on a sphere? What would the be steps for getting the formula for non-spherical curved space? [link] [comments]  |
| What role or roles do archaebacteria play in humans? Posted: 18 Oct 2016 09:08 AM PDT I've been given this topic to present on, and I know nothing about it. My presentation thus far is very bland; can one of you smarter people share some "exciting" or at least moderately compelling information about this subject? [link] [comments]  |
| Posted: 18 Oct 2016 08:16 AM PDT Basically I attended a talk yesterday on the recent nobel in physics tailored for someone with no background of physics. The speaker discussed what creates a insulator (large gap between conduction and valence bands). I know that energy levels are supposed to be discrete. Why do they form a band in materials?

| Is noise additive in terms of causing hearing damage? Posted: 18 Oct 2016 08:29 AM PDT For example, say I'm listening to my non-isolating headphones in a quiet room with the average level from the phones being 80 decibels (or whatever is considered the max for longer-term safe listening). Now say I take the same phones, music, average playback level, etc. and fly across the US in a shitty economy class seat near the engines. I can still hear my music okay over the rumble of the engines, but they certainly are loud. Am I now damaging my hearing as a result of the combined sounds or does it just not work like that? If not, why? [link] [comments]  |
