| Posted: 30 Aug 2020 08:55 AM PDT I was listening to a podcast and they suggested that since the H1N1 virus came to be, due to genetic drift and shift, the virus itself has swapped genes becoming H2N2, then H3N2, which also still circulate though out the population. Is this true? I was doing a little of my own research but I am not sure what exact keywords I would use to find an accurate answer. [link] [comments]  |

| Does the airflow behave differently after Mach 1? If so, how? Posted: 30 Aug 2020 07:41 PM PDT Hello there. Well, the question basically sums it up. I went to a technical school and kind of know how the air molecules behave or "flow" under certain circumstances, but I have no idea nor I was able to find any information about if it behaves in a particular manner after it surpasses the speed of sound [link] [comments]  |

| What happens to the water that goes inland after a tsunami? Posted: 31 Aug 2020 03:19 AM PDT I saw a short clip of the Japan tsunami and it said it went up to 3 miles in land. The clips show huge quantities of water flooding the towns with buildings almost entirely submerged in water. My question is Where does all that water go? How do towns go back to normal?

| How do scientists find functions in real life? Posted: 30 Aug 2020 08:11 PM PDT In calculus I learned several applications that are used in real life, such as line integrals, doubles, triples, derivatives, vector fields, integral theorems, etc, etc. I recently wondered how much mass a log had that I use to support things. Ok, I use an integral, ahh but I need to know its density function !! And its limits of integration! I learned several interesting things, but I don't know how I could apply them, because for almost always a function is needed. For example I want to calculate how much mass a train track has, for this I need to know, for example, with a double integral, how is the density function and then how are the limits of integration in expressions of x, y, z. (what is this? A cylinder? With a domain with holes ?! and then two planes ?! and for a anvil? They are very rare shapes) or I want to calculate the volume of a chair, how the **** do I do it? It is composed of cylinders, but then it has strange shapes that I do not know of any function like that Or worse, if I want to calculate how is the work that the river does to a flower that I threw, I would need to find the vector field "river". Is that how they do it? do they find functions? do approximations like Taylor polynomials? integral theorems? (even there it is necessary to know how the functions are) Sorry if I write too much, I would be happy to hear from your answers or comments [link] [comments]  |

| When a chemical reaction is “slower” than another, what actually takes more time to happen? Posted: 30 Aug 2020 01:38 PM PDT In other words, is it just the moving of atoms to different places taking longer or is it something else? I know reactions require the molecules involved to hit each other with the correct orientation and amount of energy, so is that just less likely in slower reactions and it takes longer for that event to happen?

| Is there anything that can ONLY be seen in peripheral vision, no matter what? Posted: 30 Aug 2020 02:51 PM PDT So I know that we can see better in the dark (albeit in black and white) in the corners of our vision, but the things we see in these cases - the things that we can't see when viewing head-on in darkness - are always visible when lit up. To my knowledge, at least. Could or are there any objects that can only be seen in peripheral vision? If not in reality, then what would it take for a phenomenon like this to occur in a sci-fi setting? [link] [comments]  |
| Posted: 30 Aug 2020 08:45 AM PDT Solar radiation that reaches the earth is predominantly UV, visible, and IR radiation. As visible accounts for the largest part of the radiation, it makes sense that we evolved to perceive visible wavelengths through eyes. Why don't we see IR radiation? Is it because at some point of evolution we (whatever thing we were back then) were able to see it but evolution phased it out because it's not really beneficial for our survival? There are still some animals who can sense IR radiation. [link] [comments]  |

| Does global warming effect the frequency that we will see rare cloud formations? Posted: 29 Aug 2020 02:59 PM PDT As the Earth's climate changes, will we see rare formations become more frequent, and inversely will our currently common cloud formations become rarer? I have seen a lot of cool clouds is recent posts across several subreddits. I understand that this is probably just a internet trend but it got me thinking. [link] [comments]  |
