Is the optic nerve stretchy or is there some slack to let your eye move? Posted: 24 Mar 2020 05:27 PM PDT When you move your eye to look around, does the optic nerve stretch or is there a little bit of slack inside your skull to allow the nerve to be pulled? submitted by /u/GOODHS [link] [comments]

Why does COVID-19 affect people differently? Posted: 24 Mar 2020 10:35 PM PDT This may have been asked here before, but I'm trying to understand how a virus can show completely different symptoms in one person versus the next. For example, Donovan Mitchell, a NBA shooting guard for the Utah Jazz, tested positive for COVID-19 a week and a half ago. He's repeatedly stated that he is completely asymptomatic and is feeling better than ever, even stating the he would be able to play in a 7-game series right now. But then I see stories of people in their mid-20's (around the same age as Mitchell), who appear relatively healthy, having to be put on respirators and checked into ICU. I've never heard of a virus affecting people completely different like this. For example, if two people around the same age and health get the flu, it usually affects them about the same. And even if it's not exactly the same, they both would experience negative symptoms to some degree. Why is COVID-19 so different? Any explanation on this would be appreciated! Thanks! submitted by /u/aroundzeworld [link] [comments]

Can one be tested for Covid 19 immunity? Posted: 24 Mar 2020 10:33 PM PDT I'm having trouble finding a clear answer on the internet. If a person had a mild form of the virus and wasn't sure, and a significant amount of time had elapsed, would it be possible to determine whether they were immune to the virus? P.s. If so, would they carry antibodies or other biological material that could be donated to help seriously sick people or research? submitted by /u/vinterstum [link] [comments]

Is there proof that social distancing is working? Posted: 24 Mar 2020 11:46 PM PDT So I understand the idea behind social distancing, and it totally makes sense to me. But I was wondering is there any proof that it works with COVID-19, or is it just a very logical hypothesis. Like is there data showing that countries with more social distancing have less cases of COVID-19 or something like that? And if not is there data from some other pandemic maybe? submitted by /u/lyb770 [link] [comments]

How was the social distancing recommendation of 2m/6ft derived? Posted: 23 Mar 2020 06:58 PM PDT Why was 2m/6ft chosen as the recommended distance, instead of 4ft or 10ft? Is it because the average human reach is 70cm and ( 70cm * 2 + some margin ) is approximately 2m/6ft? Do the droplets expelled by normal talking/breathing typically travel less than 6 feet? Or is there some other reason why this distance was chosen? I've tried searching online for this answer but so far I've only come across articles explaining the overall goal/theory of social distancing. I'm interested in how the specific recommended distance was chosen. submitted by /u/vitagm [link] [comments]

Why is it recommended to avoid lying down after taking iron supplements? Posted: 23 Mar 2020 08:42 AM PDT The instructions recommend staying upright for 30 minutes afterwards, why is that? I wonder why don't I see this with things like antihistamines or painkillers. It is a 200mg iron fumarate supplement, if that helps. submitted by /u/godsisreal [link] [comments]

Are quantum fields in any way similar to classical fields? Posted: 24 Mar 2020 05:45 AM PDT I understand classical fields as being functions of space with spatial(-temporal) coordinate inputs and scalar, vector or tensor outputs (like temperature being a function T(x,y,z,t) with a single scalar output). But when people talk of quantum fields, they talk of "exciting the field to produce particles" and other things that refer to quantum fields more as physical media that can be disturbed and picked apart. Am I missing something big here? Or is QFT just so complicated that it's not worth comparing quantum fields to classical ones? submitted by /u/nompynuthead [link] [comments]

Has there ever been a recorded pandemic for marine life? Posted: 23 Mar 2020 07:30 PM PDT Hi everyone, pandemics seem to be a hot topic right now, and rightfully so, but I was wondering if there have ever been any devastating marine viruses, pandemics, or plagues? Humans have a long history with plagues but I've never heard of marine life being effected by that. Thanks for your time! submitted by /u/emerson1396 [link] [comments]

Do the Nuclear Forces have analogs of the CMBR? Posted: 23 Mar 2020 07:18 AM PDT I'm guessing that like EM, at some point the universe was just cool enough that the strong and weak nuclear forces became distinct. At each of these points, wouldn't there have been a sudden burst of gluons and W/Z bosons throughout the universe which we should be able to detect? Or at least can we detect what they decayed into?

How did the Florida Everglades form? Posted: 23 Mar 2020 09:24 AM PDT I've found conflicting information about the geographical development of Florida. I've read that about 2mya the water level was 20m higher than today, but then I've also read that the Florida peninsula extended over 100mi further into the Gulf of Mexico than today. Additionally, I've read that the land was basically a desert 7500y ago, but then it was an archipelago 6000y ago?

The Spanish Flu of 1918 was a strain of H1N1, but how do we know that?

Theory of relativity, I think? Posted: 23 Mar 2020 02:58 AM PDT So I was thinking. If the Earth moves at a speed, at which the galaxy is faster, then clusters, then super clusters, how are we not smushed like pancakes? Just accelerating in G forces at rates to leave our planet is already strenuous on average human beings. submitted by /u/khamibrawler [link] [comments]

Would "field lines" be visible with a magnet surrounded by fine iron powder in space? Posted: 22 Mar 2020 07:43 PM PDT My initial question was "why does a magnet, when surrounded by iron filings/powder, show field lines if the magnetic field is continuous." That was explained by friction essentially. So what happens if you remove the friction? Would it all just... stick... to the magnet? EDIT: Or would you literally have a "cloud" of iron powder? Or some other... shape? submitted by /u/corrado33 [link] [comments]

If COVID-19 is in the same family as the common cold why should we expect a Cure / Vaccine? Posted: 22 Mar 2020 04:20 PM PDT Is the common cold synonymous with coronavirus and every time you get one it could be a different strand? submitted by /u/MaggieOfTheStreets [link] [comments]

Does the LHS @CERN generate collision debris after very many millions of collisions? Posted: 22 Mar 2020 11:21 AM PDT I know that the beams are rotating counter clockwise and that the collisions are only on the atomic scale. But, there's very many millions of them and the collisions yield new products that are detected by the experiment. My question is: is there residue of these collisions that sticks to / coats the surface of the detectors and makes them 'dirty'? I would not expect that to be the case because it's all on an atomic scale, but if you keep doing that for an appreciable amount of time, generating millions upon millions of collisions, maybe there is a cumulative buildup of debris. Maybe it might even interfere or affect the accuracy of the detectors. Is that something that is taken into account or is it complete nonsense? submitted by /u/AbulurdBoniface [link] [comments]

Why have humans evolved to touch our own faces with frequency? Posted: 22 Mar 2020 03:35 PM PDT I am a Public Health major and a large percentage of reduction strategy for neglected tropical diseases, the flu, and many other viruses is simply encouraging handwashing while trying to encourage limited "face touching". Not one of my classes has ever discussed why we touch our faces so often? From a limited google search, it seems most other creatures do not touch their faces nearly as often. Considering one of the easiest ways to reduce viral spread is avoiding hand contact with your face, why did we evolve to touch our face so often? submitted by /u/julioslotus [link] [comments]

Does being infected with one virus reduce the chance of coinciding infection by another virus? Posted: 23 Mar 2020 12:07 AM PDT This is a hypothetical question but could it be developed into an effective vaccine in future. submitted by /u/hypd09 [link] [comments]

Are proton-proton and neutron-neutron nuclear force interactions provide significant attraction? Can one hadron only 'bind' with another hadron via the nuclear force? Posted: 22 Mar 2020 01:38 PM PDT Protons and neutrons bind by residual strong force. Can these two bind with each other with any significant strength? Also can one neutron only bind to one proton and vice versa? submitted by /u/thejeran [link] [comments]

Does software suffer from "wear and tear"? Posted: 22 Mar 2020 03:57 AM PDT As the tittle says, does software suffer from wear and tear from constant use?

Is this way how sofware gets corrupt? submitted by /u/ProfessionalGrumpy [link] [comments]

Why does the recent earthquake in Croatia occur, despite its epicenter not on any major plate boundaries?
