| how is protium stable without a neutron? Posted: 13 Oct 2016 06:19 PM PDT I am in grade 9 so please keep it simple :) but without a neutron, shouldnt the electron and proton result in fusion and release energy since negative and positive charges attract? (Correct me on anything and everything, just looking for knowledge) [link] [comments]  |

| Posted: 13 Oct 2016 09:12 PM PDT I meant to say: Can we accurately predict the properties of a NaCl molecule by knowing the full properties of Na and Cl separately? Edit: For those interested in the philosophical implications which basically proved to me that this doesn't violate reductive physicalism: http://individual.utoronto.ca/jmwilson/Wilson-Non-linearity-and-Metaphysical-Emergence.pdf [link] [comments]  |

| Posted: 13 Oct 2016 07:06 PM PDT Basically is the asteroid field like science fiction showing it very dangerous to pass through or are things spread out enough that it isn't as difficult as pop culture suggests? [link] [comments]  |
| Posted: 13 Oct 2016 06:31 PM PDT I've heard lots of talk of other planets that may support life based off of guesses at their composition and atmosphere, and these are often hundreds of light years away. Yet we are still not sure if there are even other planets in our solar system beyond Pluto (Planet nine, for example). Is this due to a difference in how they are detected, or is our knowledge of the potential life-supporting planets heavily exaggerated? [link] [comments]  |

| Posted: 13 Oct 2016 03:14 PM PDT Fear not, this is not a homework quetsion, but is something I was thinking about after watching this video about entropy by Steve Mould. He mentions that if you had a box filled with half red balls and half blue balls (assuming they all lie in a flat configuration) and shook the box up, that you would have a higher entropy in the box due a "statistical phenomena" because there is only one possible outcome that results like this. However, a commenter mentioned that all of the red balls can be interchanged with one another, and all of the blue ones as well. However, wouldn't this result in a lot more possible combinations than one? I'm not very good at statistical calculations, but as a quick shot at, I thought that the possible configurations of (50) red balls, as well as the (50) blue balls for each configuration of the red, would amount to a total of 50!2 possible combinations that would all result in having red on one side and blue on the other. This is smaller than 100! (what I presume to be the total possible configurations of the entire box), however, it is much larger than one. Any insight as to where I have gone wrong, or a more detailed explanation on how entropy statistics like this are calculated are appreciated and thanked for in advance. [link] [comments]  |
| How does the revised galaxy count effect Dark Matter? Posted: 13 Oct 2016 10:59 PM PDT Hi All I was just wondering how the revised galaxy count effects the issue of dark matter. As I understand it dark matter makes up a large proportion of the universe we cannot see, do the extra galaxies go any way towards removing the need for dark matter? [link] [comments]  |
| [Geology] What effect do earthquakes have on the relative chronology of layers of dirt/rock? Posted: 13 Oct 2016 06:12 PM PDT Suppose an earthquake a long time ago caused layers of ancient dirt, rock and sediment to become exposed on the surface. Today, what might that look like? What clues might exist to indicate that an earthquake took place? If new sediment began to accumulate on it, could the mixup of old dirt and new, make it difficult to figure out the relative ages of different depths of dirt? If an area suffers from a lot of tectonic activity, like the Caribbean or California or the Himalayan mountains, is the area tougher and/or easier to analyze? What sort of patterns deep in the ground might exist to indicate what's going on? For example, without knowing the Indian plateau is moving towards/into Asia, could a geologist in the Himalayan mountains deduce the plateau is moving, based on soil samples from various depths in the ground? Ignoring the fact that there's giant mountains all around, could the tectonic movement be figured out from underground? [link] [comments]  |
| Posted: 13 Oct 2016 03:06 PM PDT Google tells me that "Your odds of being struck by lightning this year are 1 in 960,000". If I get struck by lightning, and I'm not in a profession or position that makes being struck by lightning more statistically probable than anyone else, why does the probability of me getting struck again lower?

| Does Taylor's Theorem imply Fourier's Theorem? Posted: 13 Oct 2016 01:03 PM PDT If all continuous functions can be represented by polynomials, and sin/cos are continuous, that implies every form of sin or cos has their own Taylor series. Does this mean that every function that has a Taylor series can be translated to a series of equivalent sines and cosines? [link] [comments]  |
| Why do peak flood waters occur days after the raining/hurricane has stopped? Posted: 13 Oct 2016 09:57 AM PDT I live in North Carolina and have a lot of friends in the eastern part of the state who are experiencing heavy flooding as a result of Hurricane Matthew. I keep seeing reports saying that peak flooding levels will occur on Friday, but it stopped raining on Saturday/Sunday. What gives? [link] [comments]  |
| How is the probability of a nuclear reaction occurring calculated? Posted: 13 Oct 2016 11:58 AM PDT I noticed that when you fire an alpha particle, neutron, or other particle at certain elements, there can be a variety of different reactions: For example, deuterium fusion can results in three different outputs (Helium, Tritium, or another I can't remember) with a fixed probability for each. With the exception of neutrons it seems that it is quite rare for the new nucleus to simply be the old nucleus plus the amount of neutrons and protons in whatever you shot at it (alpha, proton, etc) when I look in a table of reactions. How is this probability calculated? Is it just observed and recorded as what it is, or is there some sort of mathematical way to figure out these probabilities? [link] [comments]  |
| Posted: 13 Oct 2016 07:26 PM PDT I think vestigial features are one of the coolest aspects of Evolutionary Biology and today I found out that abs also fall under the vestigial category. Unfortunately, a Google search into what purpose they served and when didn't yield me many relevant/reliable sources. Thanks in advance! [link] [comments]  |
| Quantaum teleportation and how it works? Posted: 13 Oct 2016 06:51 AM PDT I have read a couple things about it and the most recent was from a chapter in "Beyond our Future in Space" by Chris Impey. He probably did a great job explaining it but the only I got out of it is that an object from one place can be broken down to particles and teleport to another place where the particles will be put back together. It seemed very weird. [link] [comments]  |
| What is the main difference between organic PVs and inorganic PVs? Posted: 13 Oct 2016 10:32 AM PDT Aside from the material, what are the main differences between organic solar cells using fullerene derivatives and inorganic, silicon based cells? I guess I should also add CdTe cells and all thin films. Are there differences between the mechanisms to convert energy? Sources would be great if possible. Thanks! [link] [comments]  |
