| What determines which areas of the brain are damaged during hypoxia? Posted: 07 Nov 2018 04:53 AM PST When the blood and oxygen supply is cut off to the brain what determines which regions of the brain are damaged? Does the motor cortex tend to be more susceptible to damage because in states of hypoxia the body is trying to move? [link] [comments]  |
| Posted: 07 Nov 2018 06:21 AM PST Traditional horizontal axis https://imgur.com/gallery/nIFOgee Rarely used vertical axis https://imgur.com/gallery/Cny1Hys I'm assuming it has to do with efficiency but does anyone know actual ratings? What's the most efficient vertical turbine and how does that efficiency compare to traditional ones? Is it half as efficient? Is it better than half? When is a vertical a better option? Thanks!

| Posted: 07 Nov 2018 06:04 AM PST So, in the scale of billions of years, is it even possible yet to figure out which larger star or stars our system came from, and who are our brothers and sisters on the cosmic scale? [link] [comments]  |
| Does a light beam emitted from a laterally moving source have "sideways" movement, or only straight? Posted: 07 Nov 2018 07:02 AM PST I understand that light emitted from a source traveling at n speed (toward the observer) will still move at only c speed (not c + n speed). But how will a light beam act when emitted from a source moving lateral to the [stationary] observer? If I fire a gun from a moving platform, at a stationary target, I have to fire before my sight cross the target, because my lateral movement is imparted to the bullet that leaves the muzzle. But how about a beam of light? Does a lateral moving source add lateral movement to the light? Or does a photon, once emitted, travel in a strictly straight line from its source? [link] [comments]  |
| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 07 Nov 2018 07:11 AM PST 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]  |
| Why do electrical outlets sometimes send sparks or jolts when plugging or unplugging? Posted: 06 Nov 2018 11:36 PM PST It doesn't seem consistent, so I'm wondering what factors make it more likely. [link] [comments]  |

| In terms of the standing-wave model of electrons, what are chemical bonds? Posted: 07 Nov 2018 05:27 AM PST Title says it all really. I don't really know anything about orbital shapes other than what I've read here, so if they have anything to do with it you may have to walk me through it lol. But I always wondered what caused atoms to bond, is it like constructive superpositions? Or is that a no-no for matter. Edit: in the title I meant electron orbits, not just electrons themselves, though I guess it still kind of works [link] [comments]  |
| Posted: 07 Nov 2018 05:05 AM PST at my theoretical electrodynamics tutorial last week, the tutor just said that if thats the case, weird things happen but he didnt bother to elaborate further but now im curious thanks in advance for the answers [link] [comments]  |
| Are atoms considered fluid or solid? Posted: 07 Nov 2018 04:01 AM PST I understand that it depends on the attraction between the atoms to deter main solid and fluid but if you needed to classify a single atoms what would you do? 2bd question, are protons neutrons and electrons solid or fluid.

| How are extra-galactic gamma rays detected and imaged? Posted: 07 Nov 2018 02:18 AM PST I'm a bachelor student in astrophysics and in one of our classes about detecting and measuring intensities of EM-waves we saw that gammarays are not detectable with optical telescopes because the mirrors would simply absorb the gammafotons. What device or technique is used to form an image? And why can't a CCD-camera be used for such observations? EDIT: I've done some more research and it seems like they use scintilationdetectors.

| What are the ways heavy elements get created? Posted: 06 Nov 2018 04:37 PM PST I learned that heavy elements are created in stars and distributed through the universe by novas in grade school. Sometime after that I became aware that red giants dissipate with age, and it seems that some of that material must be heavy elements. In the last year or two, I've read about neutron star mergers scattering large amounts of heavy elements. What other ways exist? Do the jets from the galactic black holes also transform the material they eject into heavier elements? [link] [comments]  |

| Posted: 06 Nov 2018 10:40 AM PST I am aware that the sun uses this method, and that it takes millions of years for it to work, but are there any theories or proposals for an artificial process like this that is more expedient? [link] [comments]  |

| How does lead get in water from pipes? Can lead be filtered out of water? Posted: 06 Nov 2018 10:44 AM PST Can lead molecules be filtered out of drinking water? A quick Google search revealed that, yes, it can be filtered out. If so, why haven't schools and public institutions (Flint, MI) installed filters as a temporary fix until the pipes can be replaced?
