| Posted: 12 May 2020 05:21 PM PDT For example, what is the impact of 1sq meter of solar panels versus 1sq meter of sunlight on regular ground in regards to thermal energy. Does solar efficiency play a role? Lots of articles talk about how polar caps are important for reflecting incoming sunlight back into space. I was wondering how some of the technologies and materials we place outside affect the net thermal energy captured by the planet. So controlling other variables (weather, greenhouse gases, etc.) what impact do these types of materials have on warming the planet? In the extreme, would a planet completely covered in solar panels be a different temperature than one that does not? [link] [comments]  |
| Posted: 13 May 2020 04:00 AM PDT Hello, Reddit. I'm Dr. Darío Gil, Director of IBM Research. I lead innovation efforts at IBM, directing research strategies in areas including AI, cloud, quantum computing, and exploratory science. Under my leadership IBM became the first company in the world to build programmable quantum computers and make them universally available through the cloud. I recently was appointed a member of the National Science Board, and as an advocate of collaborative research models, I also co-chair the COVID-19 High-Performance Computing Consortium, which provides access to the world's most powerful high-performance computing resources in support of COVID-19 research. IBM is simultaneously creating the supercomputers of tomorrow: quantum computers. Ask me anything about the next great frontier of computing: quantum!

| How does the rotation of the earth affect air travel? Posted: 12 May 2020 07:09 PM PDT When you take a flight, one can imagine how you can either fly along with the rotation of the earth or against it. Yet a quick google search shows, a flight from New York to Tokyo is about the same time as a flight from Tokyo to New York. Why is this, and how exactly does the rotation of the earth affect our air travel? [link] [comments]  |
| Can you tell a right eye from a left eye like you can with bones? Posted: 12 May 2020 11:23 PM PDT I know that with bones, you can tell which side of the body it came from due to its morphology, but an eye is ovoid. If someone were to find just an eye, could they be able to figure out which side the eye came from? If so, what indicates the difference? Or is it too difficult to tell because of its specific shape?

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 13 May 2020 08:08 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]  |

| Why is it that heat always rises? Does heat always rise? are there exceptions? Posted: 13 May 2020 05:51 AM PDT It seems like a really simple question but I genuinely don't understand why hot goes up.. [link] [comments]  |
| Why are people unable to speak in unison on Zoom? Example the closing prayer in AA meetings. Posted: 13 May 2020 05:36 AM PDT At the end of AA meetings we often end with a recitation of the serenity prayer - and in real life it is pretty much said in sync. Not completely but close. In Zoom meetings everybody seems to have their own pace and it's all over the place. I get it that the signal has to go to a server somewhere and back but 180k miles per second is pretty fast and it does not seem like it would be as far off as it is. Is it that our ears can distinguish such small differences? [link] [comments]  |

| How is a large app simultaneously worked on by multiple developers? Posted: 12 May 2020 06:10 PM PDT I'm pretty new to servers/backend, but as far as I know, if an app is closed-source, how are developers able to access the code, and change it, while this process is simultaneous across different departments and such?

| Posted: 13 May 2020 04:06 AM PDT I had been reading some articles lately that was talking about the begining of a polar flip (which takes a long time) and it was discussing how that was effecting the strength of the magnetosphere. I was wondering if this is caused by global warming or is it increasing global warming? It seems like it would at least add too it, but it always seems like either good articles dont want to touch the global warming aspect or they are click bait looking to take all the blame off fossil fuels. It would really be nice to know from someone who actually has studied this, and isn't pushing an agenda. [link] [comments]  |

| Posted: 12 May 2020 09:18 PM PDT I am a bit confused (and getting a little frustrated) trying to get a straight answer about these. For a bit of background, I'm a 3rd year grad student in physics but my program has not had a course offering in GR available since a year before I started. I have been trying to self teach basic GR, and have successfully derived the TOV equation in between all the normal grad student/TA duties. But, there are three things I am still quite unclear about: the polytropic constant used for neutron star models (I've seen 0.25, 100, 5.38x109 and 1), the adiabatic index gamma (I've seen 4/3, 5/3, and 2), and central density (I've seen 1 used, but generally is unstated). I'm just hoping to get clarity on these choices, in the hope of putting together a simple TOV numerical solver in Python that gives the 1.44 solar mass, approx 10 km result to see it with my own work, if possible. Cheers, stay safe and healthy, and thanks for any elucidation! [link] [comments]  |

| When I press backspace or delete on a letter as I'm typing, where does it go? Posted: 12 May 2020 11:49 PM PDT I guess what I'm really getting at is what's the logic behind how text appears/disappears/moves? What is the data structure that stores text as I'm editing it? How am I able to copy something and paste it in the middle of text multiple lines/pages above? [link] [comments]  |
| Why do we create igM antibodies first? Posted: 12 May 2020 02:19 PM PDT My understanding is when a t cell activates a b cell it goes into germinal center and goes through class switching. Shouldn't we start off with igG antibodies first? [link] [comments]  |
| Why must Venturi respirator valves be replaced every 8 hours? Posted: 12 May 2020 02:01 PM PDT This is the valve type that was in short supply, so some people started 3D printing replacements. [link] [comments]  |
| Is there evidency of viral latency in COVId19?is anybody ecperiencing lingering effects? Posted: 12 May 2020 03:50 PM PDT A lot of reports(check last article in NYtimes) of people that were infected and 3 months later they have lingering effects that appear neurological in nature..does the body can get rid of a virus that is hiding in the brain?have anybody experienced this after the virus?any evidence in favor of viral latenxy on covod19?
