| Posted: 23 Mar 2016 08:36 AM PDT I can't remember the exact question, but it had to do with the melting of Antarctica or something there that despite it melting water levels wouldn't increase because of water displacement. [link] [comments]  |
| what are the large voltages described in particle accelerators measured against? Posted: 24 Mar 2016 07:21 AM PDT in press releases from the LHC, proof of the higgs was demonstrated by evidence occurring at huge voltages. what potential differences are these particles being measured against? and we read claims of gigantic voltages made in reference to the overall power of particle accelerators. what source are these voltages measured against?

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 23 Mar 2016 08:02 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| Posted: 23 Mar 2016 11:08 PM PDT I know that if you burn certain elements it can make fire a number of colors, but why is it normally the orangeish-yellow color we know it as? [link] [comments]  |
| How do impact craters on icy bodies like Callisto/Europa differ from rocky bodies like the moon? Posted: 23 Mar 2016 10:04 AM PDT I've been learning about the cratering process on the moon, and how craters transition from simple to complex craters. How does this process or the cratering process in general differ on icy bodies? Are they expected to be the same? [link] [comments]  |
| Why are there nucleoside antiviral drugs but no nucleoside antibiotics? Posted: 23 Mar 2016 11:03 PM PDT Plenty of nucleosides have been designed that can selectively inhibit viral DNA polymerases without interfering with human ones. Given the wide evolutionary separation between humans and bacteria, shouldn't it be possible to also develop nucleoside antibiotics? [link] [comments]  |
| What's the difference between encrypting a file with AES vs archiving it with a password? Posted: 23 Mar 2016 04:07 PM PDT I read that it takes billions and billions of years to crack a file encrypted with AES. I downloaded this program called AES Crypt, which encrypts a file with a password added to it. So what's the difference between that and an archive program like winrar or winzip, which you can also add a password.If a password is required to access the AES encrypted data file and a zip/rar file, shouldn't they both be of the same strength? If you brute-force attack both types of files, shouldn't you crack them at the same amount of time? Thanks. [link] [comments]  |

| Are uncertainty calculations faulty? Posted: 23 Mar 2016 06:45 AM PDT In school, we have been taught that with division and multiplication of numbers with uncertainties, you must convert the absolute uncertainty into a percentage uncertainty. You can then solve the problem and add up the uncertainties to obtain a final uncertainty. However, a problem arises with the equation 10+-1/2+-1. Regular uncertainty calculation would suggest to convert the uncertainties into 10+-10%/2+-50%, with the result then being 5+-60%. The problem with this answer is that the maximum answer is actually 11 (11/1), which is far above the uncertainties maximum of 8. And the lowest result based on the obtained answer is 2, but the lowest actual result is 3 (9/3). Am I doing something wrong, or are uncertainty calculations faulty? Thankyou for any help, and sorry for the wall of text, I thought it was necessary to explain my situation. [link] [comments]  |

| To what extent does Jupiter protect Earth from comet impacts? Posted: 23 Mar 2016 05:43 PM PDT To what extent does Jupiter block or deflect celestial interlopers from colliding with Earth? Would the chances of intelligent life surviving or evolving on Earth decrease if Jupiter didn't exist? If so, could we extrapolate this to hypothesize that exoplanet systems lacking a layout similar to ours (inner terrestrials, outer gas giants) would be less likely to harbor intelligent civilization due to the vulnerability of terrestrial planets to frequent bombardment?

| [Biology] Can acquired immunity to one virus confer immunity to a different virus? Posted: 23 Mar 2016 06:48 PM PDT For example, cold virus X and cold virus Y are similar, so fighting off X will make you immune to Y. [link] [comments]  |
| Physicists, how can this universe have 26 dimensions? Posted: 23 Mar 2016 02:40 PM PDT What does this even mean, as relating to our subjective experience of the world? Are we like 2d beings living on a piece of paper, unaware of reality because all that matters is survival on that sheet of paper? Would that be an adequate way of looking at it? [link] [comments]  |
| Posted: 23 Mar 2016 10:02 PM PDT I know that recently (January this year) experiments at CERN seemed to show neutrinos travelling a fraction faster than the speed of light. What would this mean for our current understanding of the laws of physics? [link] [comments]  |
| Will the Great Lakes water level rise if the sea level rises due to global warming? Posted: 23 Mar 2016 12:49 PM PDT I have seen a lot of interactive maps lately show how coastal areas will be affected due to sea level rise. What I have not seen is how Great Lakes coastal areas will be affected by this rise. Will that water will funnel through the St. Lawrence Seaway? Do cities like Chicago, Detroit, Cleveland, etc. need to prepare? [link] [comments]  |
| Why are three of the five platonic solids made up of triangles? Posted: 23 Mar 2016 11:19 AM PDT |
| Are there more/different platonic solids in non-Euclidean geometries? Posted: 23 Mar 2016 09:25 AM PDT This video describes why there are only 5 platonic solids in 3 dimensions: using a construction algorithm that starts with some regular polygons sharing edges in the plane, and then bending along the edges into the third dimension to "close" the solid, we can only get so many solids before we can't close or fit all the polygons in the plane. But in non-Euclidean geometry, regular polygons have different internal angles. Can a different construction create new solids? [link] [comments]  |

| Posted: 23 Mar 2016 08:34 AM PDT Basically my question is, if I go the speed of light away from the earth to a distant object, then why does my clock slow down and not someone on earth? A person on earth would appear to be moving away from me as fast as I am moving away from them. Nothing is NOT moving in the universe as I understand it, but is there such thing as NOT moving through space at all and experiencing time at its most slow (the opposite extreme of my Pluto traveler)? If everything is moving, how do we know what NOT moving would be, and relative to what? [link] [comments]  |
| How does a black hole "destroy" particles bound by the Pauli exclusion principle? Posted: 23 Mar 2016 01:02 PM PDT It is to my understanding that fermions can't be at the same point in space at the same time, so how is it possible for a black hole to bring so much of then in the same place without violating the principle? This principle is still very new to me so I might understand it wrong. If so, can I have a clarification of how the principle work? [link] [comments]  |
| How do we perceive higher order derivatives of motion? Posted: 23 Mar 2016 02:47 PM PDT While it's impossible to "feel" velocity, we feel acceleration all the time. How do we perceive* jerk and higher order derivatives of motion? What are the physiological effects? *Perceive can mean feeling it ourselves or seeing it. [link] [comments]  |
