| Does the velocity of a photon change? Posted: 18 Apr 2018 04:39 AM PDT When a photon travels through a medium does it's velocity slow, increasing the time, or does it take a longer path through the medium, also increasing the time. [link] [comments]  |
| Posted: 18 Apr 2018 05:39 AM PDT Since that was probably a confusing title, here's an example: if you were sitting in the snow and it was below freezing out, yet somehow in your mind you were completely convinced that it was warm out and that you weren't cold at all, despite your internal temperature dropping, would you still start shivering?

| Posted: 18 Apr 2018 06:53 AM PDT Not asking how freezer burn happens, but rather once it happens, what are the constituents of the taste? [link] [comments]  |
| Do recreational drugs effect different ethnic groups differently? Posted: 18 Apr 2018 05:52 AM PDT I'm not trying to sound or be racist racist. I'm curious about the effects of drugs on different ethnic groups. I believe certain drugs may effect people with certain DNA SNP's differently. I put my DNA into a SNP reader and it says I could have poor metabolization to certain medications. So I was wondering if the effects of say alcohol on someone who's say British/Irish ethnicity would differ to someone who's say Japanese ethnicity. [link] [comments]  |
| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 18 Apr 2018 08:13 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]  |
| How do you determine the amount of CO2 in the air in the past? Posted: 18 Apr 2018 03:48 AM PDT Specifically for time periods before the formation of permenant ice caps? Asking because I got curious after a PBS Eons episode on the Paleogene-Eocene Thermal Maximum. [link] [comments]  |
| Does alcohol consumption have permanent negative effects on a person's intelligence? Posted: 18 Apr 2018 03:19 AM PDT |
| Posted: 17 Apr 2018 12:11 PM PDT We can recall very insignificant things like a statement, joke, image, or object from a particular moment even if we sometimes forget everything else about it. These memories can also feel very lucid, kind of like the popular statement, "I remember like it happened yesterday". Do we know the process behind it? [link] [comments]  |
| Under what circumstances could a sea or ocean become carbonated, like a tonic water? Posted: 17 Apr 2018 07:18 PM PDT |
| Posted: 18 Apr 2018 02:00 AM PDT For example the blades of a fan appear as a blur. Is there any theoretical way to see each blade moving separately? Or is it just the way light works? [link] [comments]  |
| Posted: 18 Apr 2018 12:02 AM PDT so i know that in bohr's theory it is simple to know the magnetic moment of an electron revolving around a nucleus cause it is an orbit and performing circular motion. But in an orbital where motion of electron is not specified, how are we able to know the magnetic moment it produces, by knowing the spin of the electron? and then how are we able to categorize the nature of an element in para, dia, ferro, ferri, anti-ferri? just on the basis of electron's spin?????

| Is there a venom that isn't a poison? Posted: 18 Apr 2018 01:50 AM PDT The difference between poison and venom to my low biology knowledge is that the former kills you after you ingest it while later kills you after it gets into your bloodstream. So is there any venom that can be safely digested? [link] [comments]  |
| What does this chemical notation mean? Posted: 18 Apr 2018 01:30 AM PDT I was recently in the Natural History Museum in London, where there is a wonderful geology room filled with hundreds of rocks and minerals. Looking through these I stumbled upon a chunk of Empressite which was tagged with the chemical formula: Ag5-xTe3 What does the (5-x) mean? (Apologies for the use of superscript - I have no idea how to subscript.) [link] [comments]  |
| How do most antidepressant drugs cause weight gain? Posted: 17 Apr 2018 02:32 PM PDT Do they make us eat more? Does it change the metabolism? Can they be used in anorexia? [link] [comments]  |

| Do languages that read from right to left think of time as progressing from right to left? Posted: 17 Apr 2018 02:41 PM PDT As an English speaker I, and I assume most people, think of time progressing in the forward direction to the right. For example when plotting a time line, the most recent events would be to the right, and historic events to the left. Does the direction of reading affect this? [link] [comments]  |
| What do we use our current super computers for? And why do we need for powerful ones? Posted: 17 Apr 2018 02:54 PM PDT |
| Is there a rigorous definition of “information”? Posted: 17 Apr 2018 04:18 PM PDT Is there a rigorous definition in physics of what constitutes information? Is there a difference between a hydrogen atom and a Collected Works of William Shakespeare outside of pure physical composition? How does that difference relate to the black hole information paradox? [link] [comments]  |
| How do we know that different animals see more colors than us? Posted: 17 Apr 2018 02:59 PM PDT I've been researching on color lately and how we look at it. I found a few articles that talk about how animals see more colors than us but none of them really explain it. Is there any evidence that they for sure do see more colors than us and how this been proven? [link] [comments]  |
