| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 21 Feb 2018 07:07 AM PST 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]  |
| is it possible to move an object in circular motion using magnets? Posted: 21 Feb 2018 06:33 AM PST hello I'm trying to make a device which uses magnetism. my device is like a windmill but instead, I'm planning to use magnets to move the blades. I created a miniature using a pc fan and a dynamo generator. So far it doesn't work. Is it possible to move an object in circular motion with the use of two opposite magnetic poles?

| What happens to the spin of an electron when it leaves a nucleus? Posted: 21 Feb 2018 05:31 AM PST Lets say a photon collides with an atom, causing an electron on the outer shell to be knocked from orbit. From a classical sense, I would assume it takes some amount energy to change the spin of a particle, and that this amount of energy would depend on how far it's rotated. But, if an electron flies off of a nucleus, there could potentially be a magnetic field in ANY direction that the electron will then encounter. This means that the electrons spin could change to be oriented in any direction after it leaves the nucleus. Now, please correct me if I am wrong, but if I am right that changing the spin takes energy based on how much it has been rotated, there is a violation of energy conservation somewhere here, as the photon would contribute a quantized amount of energy that wouldn't be able to account for the future measurement at an arbitrary angle with respect to its original orientation. Or, am I wrong about energy and if the spin on the electron was originally up, will it just be measured as up in the magnetic field? Thanks! [link] [comments]  |
| Posted: 20 Feb 2018 06:05 PM PST I know that the liver does about a million different things and secretes bile, while kidneys remove urea, but are there any overlapping functions? [link] [comments]  |
| Are there positions of a chess board that are impossible to achieve legally? Posted: 20 Feb 2018 03:15 PM PST If I were to pick up a bunch of chess pieces and put them arbitrarily onto the board, is it possible for me to arrange them in such a way that two players could not eventually create the same state from the start of a game? Assuming a legal number of each piece, obviously. [link] [comments]  |
| Are there any materials that only allow radio waves to pass through in one direction? Posted: 20 Feb 2018 06:12 PM PST Basically the title. I'm curious to see if there any materials that block radio waves coming in from one direction, but completely reject them from the opposite direction. If not in the radio part of the spectrum what about other parts of the em spectrum? [link] [comments]  |

| Why do martian rovers last so much longer than planned? Posted: 20 Feb 2018 07:58 PM PST It almost seems as if NASA underestimates the missions durations on purpose to then be able to say that some rover lasted X times more than planned. Like Spirit who was only supposed to last 90 days, I find it hard to believe that the sent a super expensive robot to another planet and only expected it to work for a months and a half. Instead its 6 years of operational time seem more reasonable, even a little less than expected. So does NASA underestimates on purpose or what? [link] [comments]  |

| Posted: 20 Feb 2018 09:09 AM PST This is always something I have wondered and been fascinated with more so than the discovery itself. It had to have been something that shook the community to it's bones (pun intended) [link] [comments]  |

| Is there a theoretical limit to how many protons an atom can contain? Posted: 20 Feb 2018 12:35 PM PST I'm very interested in physics, but mainly study it by myself on the Internet. I see in the periodic table that new elements are made in particle accelerators, by bombarding an element with other particles. So is there a limit to how heavy an element can be, or could we in the future discover a stable element much heavier than we know today? [link] [comments]  |
| How do scientists assess/prove the age of ancient foot prints? Posted: 21 Feb 2018 12:26 AM PST I seem to see a news article about every two or three months about archeologists finding a set of foot prints that are tens to hundreds of thousands of years old. Example article How do they determine how old the foot prints are? Thanks! [link] [comments]  |

| At what frequency does a repetitive sound become a solid sound? Posted: 20 Feb 2018 10:43 AM PST For instance, if you were able to beat a drum fast enough, at what BPM would it sound like a continuous noise? [link] [comments]  |
