| Posted: 08 Aug 2020 03:14 PM PDT When the pandemic started, most of the attention was on "asymptomatic" infectees, but I've seen more people saying many of them may have instead been pre-symptomatic. What is the number of asymptomatic people that never get symptoms, and is there any differences between pre- and a- symptomatic people? [link] [comments]  |
| How can they simplify the three body problem enough to be used by modern computers? Posted: 08 Aug 2020 02:26 PM PDT Warning, I only got through first year calculus and it was many years ago. I watched that short video explaining what makes the 3 body problem so hard. Can they reduce it to something more like a two body problem by acting as if the center of mass between star A and B is one body and the center of mass between star B and C is a second body to help get it closer to solvable (for example)? I'm just wondering if there is way to explain how it gets simplified enough for modern computers to attempt to solve it. A way which a non grad student+ in physics/math might be able to understand.

| Earthquakes when there are no nearby fault lines? Posted: 09 Aug 2020 07:12 AM PDT We just recently had 5.1 magnitude earthquake in Sparta NC, the nearest fault line is in the middle of the Atlantic Ocean. Any explanation to why this could happen? [link] [comments]  |

| Why do Earthquakes radiate from a single point? Posted: 09 Aug 2020 06:28 AM PDT It seems like plate slippage would result in a wide band of maximum intensity rather a single epicenter as the map usually indicates. Any geologists have an explanation? [link] [comments]  |
| Are tumor suppressor genes just uniquely susceptible to methylation via suppression? Posted: 09 Aug 2020 12:52 AM PDT Like, hypermethylation (and excess folate supplementation) is associated with higher cancer risk, even though methylation tends to turn off genes rahter than turn them on (and TET enzymes the reverse,. and lowered TET also associated with higher cancer). So this seems to imply that tumor suppressor genes are just uniquely susceptible to methylation [link] [comments]  |
| What does the crater of a nuclear bomb contain? Posted: 08 Aug 2020 11:12 PM PDT With such high temperatures and forces, what is the material like at the blast site? Is it smooth and lava like or just rubble? Is there the potential for diamond formation? [link] [comments]  |
| At what distance would it become physically painful to be near a black hole? Posted: 08 Aug 2020 11:51 AM PDT Reading about the effects of black holes, its clear one would become stretched, compressed, or just torn to pieces when entering the singularity. But on approach, assuming the transportation could sustain the forces, at what distance would a human start to feel the pain of the force from the black hole? [link] [comments]  |
| How is coast length measured/defined? Posted: 08 Aug 2020 10:17 AM PDT When you look up almost any geographical feature with a coast on Wikipedia, it will usually mention coast length among its main features. It will also have a little asterix by that number which will lead to a footnote saying how this number is dubious or downright pointless and useless due to problems arising from semi-fractal nature of coast. This length can be made arguably large just by changing the ruler size. And yet, coastline/shore length data can be found for pretty much anything and countries are often compared by their coastline length. Where do all these numbers come from? Is there a well defined ruler or "coast resolution" that "the world" in general is using? For example there are values given for shore length for Baikal and Tanganyika lakes. Are those values comparable (well-ordered for those mathematically inclined)? [link] [comments]  |

| Where is the waterfall on the Detroit River? Posted: 08 Aug 2020 11:24 PM PDT I saw in a video that said that the reason Niagara Falls exist is because Lake Erie is lower than the rest of the lakes. And because Lake Ontario is higher, the Niagara waterfall is the point were the water drops to the lower point. That makes sense but Lake Huron also feeds water into Lake Erie through the Detroit River. So where is the waterfall on that river? [link] [comments]  |

| Do people high higher basal metabolic rates require more rest? Posted: 08 Aug 2020 11:37 AM PDT Such people burn more calories whilst doing nothing: their basic bodily functions use up more energy. So, all else being equal, do they require more rest as a result? [link] [comments]  |
| Posted: 08 Aug 2020 08:18 AM PDT So, if you feel right behind your knee on the left and right, what are the very prominent tendon-like structures that you can feel also going up the back of your thigh and then seem to insert somewhere in the hamstrings? Can't find definitive answer on Google. Thanks. [link] [comments]  |
| Posted: 08 Aug 2020 12:05 PM PDT Is it like two different images next to each other or is there a more 360 degree field of vision? [link] [comments]  |
| Can you overcharge your batteries? Posted: 08 Aug 2020 11:46 AM PDT Maybe it's because I'm gen-x or something, but I can't shake this feeling that devices should not be charged for too long. Do modern batteries and devices really have the ability to stop charging when full? And how do they know? [link] [comments]  |

| How do damaged bone cells create an electric field, and how does this promote healing? Posted: 08 Aug 2020 05:37 AM PDT https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3145421/ "In the early 1950s, Fukada and Yasuda2 demonstrated that when stress is applied to bone in such a way to cause deformity electrical potentials are generated, in areas of compression the bone was electronegative and caused bone resorption, whereas areas under tension were electropositive and produced bone."

| Why do heavy metals form in veins? Posted: 08 Aug 2020 11:21 AM PDT I might have some premises wrong, but anything heavier than iron only forms in a exploding star, right? If this is the case, why aren't the metals more evenly distributed? What makes them clump up with their own kind so that it eventually forms veins? I would expect something like gold to be more like aluminum, and as I understand it, aluminum doesn't form veins, but it's just scattered everywhere and it's drawn from dirt. I suppose the gravity or Earth and the heat in it's core could cause some separation, if it isn't turbulent enough down there. And it probably help that stuff like gold is less reactive than other elements, maybe? What am I getting wrong? What am I missing? [link] [comments]  |
