| Two of the same type of metals will bond together in space? Posted: 01 Jul 2016 03:58 AM PDT Just got a interesting Snapple fact! Says that if two of the same type of metals touch in space they will bond together permanently! Why does this happen? And when it does how fast does it occur? [link] [comments]  |

| What would happen if you explode a hydrogen bomb in a kilometer-thick metal sphere? Posted: 30 Jun 2016 06:22 PM PDT For example a 10 megaton hydrogen bomb going off in a kilometer thick lead sphere. Will it amplify the explosion kind of like a boiling liquid expanding vapor explosion? Or will nothing really happen and the lead sphere would contain the explosion? [link] [comments]  |
| I read that astronauts DNA can be “shattered” by cosmic rays, what does this actually mean? Posted: 30 Jun 2016 07:33 PM PDT My question came from reading an article about our Sun going blank and maybe heading toward a 'solar minimum'. Which causes cosmic rays dangerous to astronauts, article link here: http://www.news.com.au/technology/science/space/the-sun-has-gone-blank-twice-this-month-this-is-what-it-means/news-story/d775ecf894ab68415ed0108ced31a4e2 [link] [comments]  |

| Posted: 30 Jun 2016 05:52 PM PDT I've heard that in the 60s the UK switched from one type of gas for stoves (which had carbon monoxide in it) to another (which didn't), and thus people were no longer able to asphyxiate themselves with carbon monoxide. It apparently led to an overall reduction in suicide rates, the explanation being that suicidal people don't easily take the final step to try to kill themselves, and if there's no convenient method, often suicidal urge passes before they can find a way to follow through. I also read (from a non-scientific source; just a news story) that something similar happened in Sri Lanka when pesticides were switched so they were less dangerous for humans. This is the same logic with putting barricades or nets that make it harder to jump off bridges. But is this true? Or is it just correlation, not causation? [link] [comments]  |
| What are birds sleep pattern like? Posted: 30 Jun 2016 08:07 PM PDT Well I want to expand this question a bit more. How do mammals, reptilian, and avian sleep patterns differ? Which species sleep more and less and what are the advantages they get for doing so. Finally why the fuck do roosters go on and on from 4 a.m. to 7a.m. is that their mating time? [link] [comments]  |

| Is there a highest possible state for the quantum harmonic oscillator? Posted: 01 Jul 2016 02:48 AM PDT The classical potential of an idealized harmonic oscillator describes a parabola going to infinity. There could therefore be an infinite number of eigenfunctions of the quantum harmonic oscillator. Is there a certain limit imposed by the rules of quantum mechanics or does the oscillator just sort of break down at certain energies like a classical spring that would be irreversibly deformed?

| How much did the Earth's average temperature decline due to the Chicxulub Impact? Posted: 30 Jun 2016 07:30 PM PDT We know that the asteroid impact that tool place at the end of the Cretaceous had various deadly effects. But I wonder how bad the temperature drop was, and if the lowered temperature was the main agent of ecological collapse, or if poor light levels (cutting down photosynthesis) were.

| What influences the varied effects of different strains of cannabis? Posted: 30 Jun 2016 11:27 PM PDT I'm looking for a more in depth answer than 'genetics brah!' Is it just about THC/CBD ratio? Other cannabinoids? Terpenes? What? [link] [comments]  |

| Is basal metabolic rate related to heart rate in humans? Posted: 30 Jun 2016 11:39 PM PDT Most of the relationships I've seen for calculating BMR do not factor in heart rates, but calculations for calorie use during exercise are all related to heart rate. In people with elevated hear rates (e.g Tachycardia sufferers) is the basal metabolic rate also increased? [link] [comments]  |
| why do auroras only happen at the poles? Posted: 01 Jul 2016 04:33 AM PDT I thought it happened because the sun's radiation kinda skimmed across the atmosphere on a tangent to the earth's surface... but doesn't that happen at other latitudes as well?? what am I missing? [link] [comments]  |
| How were the Appalachian Mountains and Allegheny Plateau formed? Posted: 30 Jun 2016 10:27 PM PDT Hello! I'm doing some research for a project and I'm trying to wrap my head around the formation of the Appalachian Mountains and the Allegheny Plateau (specifically in Southeastern Ohio). From what I've gathered so far - The mountains were first formed as part of the Central Pangean Mountains when Laurussia and Gondwana collided. Rivers and streams began to flow down from the mountains and formed a large delta to the north and northwest. Then, over time, the mountains slowly eroded down fairly small. At the same time, Pangea began to break up, and the release of the pressure caused the mountains to further subside until they were eventually under water and formed the Appalachian Basin. Then, during the cenozoic era, uplift began again and the mountains began to rise once more. The delta and part of the sea floor to the northwest also began to rise and that formed the Allegheny Plateau, hence why it's flat (except where it's been eroded away, of course). Am I anywhere close to being right on any of this? I am NOT a geologist, but I'm really fascinated by these events and really want to get my facts straight. Thanks!! [link] [comments]  |
| What would be the effects of a major asteroid impact in the ocean compared to one on land? Posted: 30 Jun 2016 06:11 PM PDT This article made me realize that I have never heard of any significant asteroid impacts occurring in the ocean. But, since 70% of the Earth is water, I assume it must happen (relatively) often. If such events have been recorded, how did we find evidence of them, and how would they affect the planet compared to an impact on land? [link] [comments]  |

| Posted: 30 Jun 2016 08:44 PM PDT What, and why is there a difference between fine and gross motor skills? From a neurological perspective why is it possible to be competent at one and incompetent at the other? Is coordination an inherited trait or is learned? [link] [comments]  |
| Posted: 30 Jun 2016 07:45 PM PDT Hey guys, I'm studying for grad school prelims and trying to understand classical perturbation. Sadly, I'm having some difficulty. I'm working through Goldstein, and his discussion starts in the HJ formalism. I don't really "get" the idea of HJ - I'm not sure what the point is, or how it really works. I've read through the relevant chapters in Goldstein (and other texts I found online) several times, and it still isn't clicking. I've tried to find some other resources, but so far all the texts and professor notes I can find follow the same tract as Goldstein. Is this strictly necessary? Do I really need to use the HJ formalism to study classical perturbations? Can't I just work with good ol' q and p and find the same solution? [link] [comments]  |
| Posted: 01 Jul 2016 06:57 AM PDT Gravitational Waves are basically ripples in the fabric of space time, What is the maximum speed at which these ripples can propagate? and is it c, if yes then why and how is it related to it ? [link] [comments]  |
