| Posted: 09 Aug 2017 08:19 AM PDT On August 21, 2017, a solar eclipse will cross the United States and a partial eclipse will be visible in other countries. There's been a lot of interest in the eclipse in /r/askscience, so this is a mega thread so that all questions are in one spot. This allows our experts one place to go to answer questions. Ask your eclipse related questions and read more about the eclipse here! Panel members will be in and out throughout the day so please do not expect an immediate answer. Here are some helpful links related to the eclipse:

| How to sum orbital angular moments to get Russell-Saunders coupling's L? Posted: 10 Aug 2017 07:19 AM PDT On this site I have found the following sentence:
I sort of understand the spin part but I have trouble with the orbital angular momentum, why can it be equal to 1 if I have two electrons both with l=1. Maybe a better example can be found in Linus Pauling's book titled General Chemistry (and this is what I couldn't understood first but even after trying to find it out on my own I'm stuck.). He shows us an example with a carbon atom. Here's my thought process on getting the Russel-Saunders symbol:
Also, if it wouldn't be that big of a trouble, could you please explan what J actually is (the subscript on the right)? [link] [comments]  |
| What is the scientific definition of temperature? Posted: 09 Aug 2017 07:12 PM PDT I have been googling this and having a great deal of trouble finding definitions that don't seem circular. In particular, the following is bothering me. Temperature seems to be defined by internal energy (u = 3/2RT) for an ideal gas. Internal energy can be theoretically defined (velocity + vibration + rotation, etc). But specific heat capacity increases with temperature for a real gas, meaning there is more energy per degree of temperature increase. How can there be more energy increase per degree if a degree is literally defined in terms of the amount of energy increase? Does temperature actually only depend on particle velocity, and other effects just happen to be negligible at normal temperatures? What gives? [link] [comments]  |
| For how long can a typical housefly stay airborne before it runs out of energy? Posted: 09 Aug 2017 01:52 PM PDT It's impressive how long it can buzz around and be super annoying without needing to eat. [link] [comments]  |

| Schizophrenia: Are voices ever perceived as benevolent? Posted: 09 Aug 2017 09:33 AM PDT From popular fiction, the voices schizophrenic people hear are always angry, insulting, or downright evil. However, do some schizophrenics hear more benevolent or supportive voices? [link] [comments]  |
| Why is the ideal gas law selective to certain types of energy? Posted: 09 Aug 2017 03:21 PM PDT Today in school I learned about the ideal gas laws. As we know, the formula is PV=nRT, t being temperature. Temperature is the average kinetic energy. We learned that there are several ways energy can be absorbed by gas molecules. This includes collision, rotating, vibration, bending. However, my teacher said collision is the only way that energy can be absorbed and that can be accounted for the ideal gas laws. Why is that? Why can't all types work for ideal gas laws? I probably said something wrong so I'll try to clarify. [link] [comments]  |
| Posted: 09 Aug 2017 02:02 PM PDT I hear things like "cancer attacks" but I don't understand how a cell made incorrectly can do that. It's not like a virus who is programmed to attack body, so how and what does it do. [link] [comments]  |

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 09 Aug 2017 08:07 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]  |
