| Posted: 01 Aug 2021 11:04 AM PDT Do we know yet if air travel has been rendered more risky today, and by what degree, as a result of COVID19 infectivity during extended time in an enclosed cabin, with at least one other person actively transmissive with the virus? [link] [comments]  |
| What happens when lightning strikes the ocean? Posted: 01 Aug 2021 12:41 PM PDT To be honest I'm not sure if lightning even strikes the ocean but if it does then what happens? Like when it strikes a pool apparently people can get electrocuted if they're in the pool, does the same thing happen in the ocean? Would the nearby fish die? How far away from the impact of the lightning do you have to be to get affected by the electricity? [link] [comments]  |
| Is our solar system self sufficient? Posted: 02 Aug 2021 12:18 AM PDT In a hypothetical universe where our solar system was the only thing that happened to form would everything turn out the same? [link] [comments]  |
| Why doesn't the immune system attack Implanon (birth control implant) in most people? Posted: 01 Aug 2021 11:50 PM PDT Why doesn't it attack and try to destroy the implant like it does with other foreign bodies? [link] [comments]  |
| Is a river's water temperature affected by weather? Posted: 02 Aug 2021 01:57 AM PDT During summer I often go swim in a nearby mountain stream with friends. According to them, It is not good to dive on sunny days after It has rained, because the rain may have cooled the whole stream. Honestly It seems very stupid to me as a reasoning since the water of the streams is running, but they still claim that the temperature is higher on sunny days. I know this is a dumb question, but could their theory be in part true? Thanks [link] [comments]  |
| Can the ISS orbit the earth in such a way that is always day? (Or night?) Posted: 01 Aug 2021 12:30 PM PDT If it so chooses? For the people onboard that is. Edit: Thank you guys for such wonderful responses. Summarizing the things I learned today for anyone else who might have a similar question:

| Why are adverse reactions to vaccines more common in younger people than older people? Posted: 02 Aug 2021 06:03 AM PDT I was looking through the adverse reactions to the COVID vaccines, and I found it interesting that the CDC report that younger people are more likely to experience (or at the very least report) an adverse reaction to the COVID vaccines than if you were older. I would have thought it would be the opposite (due to older people having weaker immune systems)? Can someone explain this phenomenon? Is this something of all vaccines? What's the biological mechanism here? Refer to table 1 of https://www.cdc.gov/mmwr/volumes/70/wr/mm7008e3.htm: 64.9% of 18 to 49 report an adverse reaction. I thought perhaps it was to do with unequal category sizes (18 to 49, versus say 50 to 64), but I don't think it is as this represents 2/3 of the total. P.S. I really don't want to get into a debate about whether or not people should take the vaccine or not (I think people at risk, definitely should). I simply want to understand why vaccines effect different age groups in different ways. (For some reason moderators removed this post... This is a legitimate medicinal question, but for some reason I'm not even allowed to ask it) [link] [comments]  |

| Posted: 01 Aug 2021 08:26 AM PDT Are they common enough to where at any given moment you're likely to be standing above a channel of caves? Or are they not quite as common. How deep could they theoretically go? [link] [comments]  |
| Would multi-party barter solve the coincidence-of-two-wants problem? Posted: 01 Aug 2021 06:30 AM PDT The double coincidence of wants problem makes barter impractical – https://en.wikipedia.org/wiki/Coincidence_of_wants If the chances of a random Joe having the thing I want are p, the chances of him having what I want AND me also having what he wants are p² But what if we connect thousands of people together using an internet clearinghouse, so that A can give something to B, B to C, C to A. That would make match-ups more likely, surely. Some software projects like haveneed.org and https://github.com/epandurski/cmbarter have envisioned this, though none is particularly well-developed IMO https://dspace.mit.edu/handle/1721.1/109184 deals with this question a bit, but only up to 3 parties, not for larger numbers of parties.
So the average time you're waiting for the software to match you with a trading partner falls from 1/p² (in a two-way swap) to 1/p1.5 (in a three-way swap), unless I'm misunderstanding the big-O notation. That is a big improvement. They also say "Our result leaves open the case of larger cycles,i.e.k >3". I'll let you read their conjecture on that. I could use an explanation from someone who understands big-O notation; how does a probability convert to a time? My question, in practical terms, is whether an eBay-for-barter would be feasible. I'm sure it's not with two-party swaps, but might it be with computer-mediated 10-party swaps? [link] [comments]  |
| How to calculate the force upon a point within a Vortex? Posted: 01 Aug 2021 02:33 AM PDT Hello! I had a bit of an epiphany yesterday night, but I don't quite get what to make of it. So i'm here asking for your help. How would one calculate the force upon a certain point within a vortex? I don't even know if Vortex is the right word - imagine a cylinder or tube, with water running through it, and i basically want to know how or what method would be used to calculate the force upon a certain point. For ease, right now i'd be happy with being able to calculate just one single point, as opposed to focusing on an equation that would cover any point. The size of this space, or the dimensions of the tube/cylinder would be relevant, however the intent is to have a way to determine what is happening at that point. I hope i'm making sense. If I need to clarify anything to make it more clear, please let me know. In my head, all of the above is very fluid dynamics related, or at least we will use some type of fluid dynamics to make such a calculation. Please help. Mahir [link] [comments]  |

| What would a neutron star look like exactly? What color does a hyper dense ball of neutrons make? Posted: 31 Jul 2021 02:49 PM PDT Most matter that we see is a jumbled collection of protons, neutrons, and electrons. But a neutron star is pretty much "oops! All neutrons!". So aside from possibly glowing from intense heat, what would it look like close up? [link] [comments]  |
