| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 11 Sep 2019 08:09 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology 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]  |
| What is the orientation of the Earth on a galactic scale? Posted: 12 Sep 2019 01:34 AM PDT Most classic depictions of the Earth in space show it in a North up orientation revolving counterclockwise around the sun, assuming the sun is also revolving counterclockwise around the center of the galaxy is this north up orientation accurate? I'm wondering because most pictures I see of the Milky Way from Earth shows it cutting across the sky at a bit of an angle. [link] [comments]  |
| How did ancient humans get sodium? Posted: 12 Sep 2019 06:55 AM PDT Humans need ~2000mg of sodium each day. These days that's easy to get because of table salt and because salt is added to most foods but how did ancient humans who ate plants and meat found In nature got any sodium? [link] [comments]  |
| Do electrons actually move around the nucleus? Posted: 12 Sep 2019 04:35 AM PDT What does it mean for an electron to have a "probability cloud"? I understand that's the probability of finding it at every point in space, but does he move? just appears ad disappears? Is it just a mathematical cloud of probabilities that collapses when measured? Or does the electron just moves around the nucleus in some way that we don't understand yet? [link] [comments]  |
| What happens to the CsCl lattice as it decays to BaCl2? Posted: 12 Sep 2019 07:06 AM PDT CsCl is used as a radiological gamma ray source for various applications. Cesium beta decays to Barium, but the two have different crystal structures. The radioactive salts are contained in a vacuum sealed tube. CsCl has an 8-coordinate "interpenetrating" primitive cubic structure (below ~450C), while BaCl2 can either have an 8-coordinate cubic Fluorite or 9-coordinate orthogonal structure. Additionally, Barium would need to pull a second chloride from somewhere to stabilize its charge. Assuming you have a large lattice of these CsCl salts, as the Cesium begins to decay, does the entire crystal structure fall apart due to the crystal structure change and charge imbalance?

| Theoretically, if you had a chunk of dark matter and put it on Earth, what would it look like? Posted: 12 Sep 2019 03:32 AM PDT Would it have a certain colour? Would it reflect light like a mirror? From my extremely limited knowledge, I think that dark matter is able to bend light due to its gravitational field. Does this mean that its ability to bend light depends on its mass? Using what we know so far, what would give the best visualisation of what dark matter looks like to the naked eye (which then poses the question, would we be able to see dark matter with the naked eye)?

| Do post-lead elements retain their unstable-ness even after forming compounds? If so, why? Posted: 12 Sep 2019 04:09 AM PDT Hi, title really says it all. I tried searching online for an answer but I'm taking my GCSEs next year, and so far my teacher hasn't gone through anything about it as far as I could recall. Could I request that the answer and reasoning be simplified for me to understand? Thanks! [link] [comments]  |
| How does/would time dilation effect hunger or the need to eat? Posted: 11 Sep 2019 09:42 PM PDT So I was reading on Wikipedia about intergalactic travel and noticed it would take millions of earth years to travel to Andromeda. However they stated that due to time dilation for passengers on the ship (if it were going light speed) it would only be a few decades. So my question is probably really stupid but how would this effect the humans on board? Would they need to store enough food to last them for the decades it would "feel" to them, or would they actually need millions of years worth of food? With zero knowledge on this stuff I'm guessing they would only need decades worth but then again if it's only that time seems to go by faster does that mean it actually does in reality? Sorry if this is just a dumb question but I was just wondering. Thank you all! [link] [comments]  |
| What is the neurochemical system involved with awareness or presence of mind? Posted: 12 Sep 2019 06:16 AM PDT There's a neurochemical pathway involved with dopamine for the reward system, etc. But I haven't found any research involving physical manifestation of the pathway for mindfulness, etc. Which might provide information about how to exercise that pathway.

| Does cognitive ability such as memory, processing decline as we age? Posted: 12 Sep 2019 02:56 AM PDT I'm almost 30, and I've noticed my memory and mental math abilities are not what they use to be. I work in accounting and when I first started seven years ago, I could see a number like $244,891.33 and instantly memorize it as I minimize the window and open up some other application. Now, this is not the case. I'm also a lot slower at doing mental math. When I was in high school, I could answer in my head something like 84*32 rather quickly. Now it takes me much longer to figure something like that in my head if I even can at all. I've tried googling and have not found any real answers. I'm wondering if this kind of cognitive decline is related to age, or if there are other possible factors. edit: I'm not asking for personal medical advice, just stating the facts that made me consider this question. I know I am not the only who has experienced and am interested in hearing if there is any research in this area. [link] [comments]  |

| Posted: 11 Sep 2019 05:04 PM PDT I'm curious what the effect that a normal visible light telescope has on radio waves or any other form of non-visible light. If there is a significant affect would that be the opposite with a microscope? If there is an affect would that also mean that looking through a telescope/microscope changes the amount radiation direct exposure you could receive from radio or other electromagnetic rays? I googled it and it seems no one has asked this before and the only results show me how large radio telescopes work. [link] [comments]  |
| Posted: 11 Sep 2019 06:55 PM PDT Also, any good links to papers or videos that explain this in depth would be appreciated! I'm having a hard time finding anything myself. [link] [comments]  |
| Posted: 11 Sep 2019 10:27 PM PDT Just came across the exciting conclusion reached by the University of Montreal's observations surrounding K2-18b showing an atmospheric water signature. Given the planet's proximity to the red dwarf it occurs to me that the stellar wind would probably be brutal. Does the water discovery show that a strong magnetosphere is likely? Could water in the atmosphere be realistically expected without one? KIs there another method for ascertaining exoplanetary magnetic properties that I'm not thinking of? [link] [comments]  |

| Why isn’t Kwashiorkor seen in more anorexia patients? Posted: 11 Sep 2019 11:54 AM PDT As someone who's battled with anorexia for five+ years and has done some pretty deep dives into the medical and science of it, I'm surprised/confused that more people who suffer from it don't exhibit Kwashiorkor. Is there a reason for that? [link] [comments]  |
| Carbon nanotubes: just carbon? Parallel tubes? Bond lengths? Posted: 11 Sep 2019 09:00 PM PDT Hey y'all. Purely out of curiosity, these are my questions about carbon nanotubes:

| How does the genomic test Oncotype DX work? Posted: 11 Sep 2019 04:22 PM PDT I get the uses of it for prognostics and the recurrence score associated with it, but I wish to understand the molecular biology behind it. [link] [comments]  |
