| What is flesh eating bacteria? Posted: 09 Nov 2018 05:27 PM PST Why is flesh eating bacteria such a problem? How come our bodies can't fight it? why can't we use antibiotics? Why isn't flesh eating bacteria so prevalent? Edit: Wow didn't know this would blow up. Was just super curious of the super scary "flesh eating bacteria" and why people get amputated because of it. Thanks for all the answers, I really appreciate it! [link] [comments]  |

| Posted: 10 Nov 2018 02:24 AM PST Could an element with, say, an expanded octet form a quadruple bond with another element? [link] [comments]  |

| Do gluons have different wavelengths? Posted: 10 Nov 2018 02:58 AM PST i Know there are 10 kinds of gluons, with different colour and all, but i was wondering if, like photons, they too could have different wavelengths. If so, what tells us that quarks don't constantly emit a wavelength of gluon that would travel outside the nucleus since it doesn't interact with the up and down quarks, kinda like radiowaves.

| Posted: 10 Nov 2018 04:11 AM PST I've seen some videos on Everett's Many Worlds Interpretation of Quantum Mechanics(WM) and it is quite appealing after some thought especially with how it deals with the the measurement and wave-function collapse problems. But I've just got a couple questions abo Lets say you have a particle when say something become a superposition the state evolves as a as a wave function in a superposition state but on measurement only a single state is measured. In the Copenhagen interpretation the wave function collapses to a single state that depend on the probability distribution of the wave function. Now with the MWI interpretation the wave-function doesn't collapse and just continues to evolve. The probabilities come from the probability that the observer is in a specific state. Let's use a simple example of a system that has a photon in the up state which is used to create a photon in a superposition of up and down. I apologize over my notation, but assume everything is a wave function: w0=u y w0 = y u w1 = y u w1=1/(2^0.5)(u+d) So say you measure the photon and you get u, the universal state in the MWI at the second measurement means you are in state 1/(2^0.5)u. This is a factor of square root of 2 smaller than the original state of u. As the universe evolves you'd get more and more scaling factors. So my question is: Why don't the scaling factors have any effect or impact on the world. My naive view is that each universe has reduced amount of energy compared to the parent universe. I have no idea if the scalling factor has anything to do with energy but I'd like some experts to explain what is going on [link] [comments]  |

| How do we know how far bodies in space are from us? Posted: 09 Nov 2018 04:19 PM PST Recently I saw an article stating "oldest star found." How do we know, since all we can do is basically look at the sky. It's not like we've been staring at a spot in the sky for millions of years and a star suddenly appears. Maybe something to do with measuring movements...? I don't see how we can know how old something is just by looking at it, especially when they all look the same (from our point of view).

| Could HIV/AIDS help with an autoimmune disease? Posted: 09 Nov 2018 09:20 PM PST So obviously this seems like a bad idea and wouldn't be recommended but could having HIV especially in the later stages help an autoimmune disease? [link] [comments]  |

| When the continents move farther from each other, would they just combine, or collide? Posted: 09 Nov 2018 11:08 AM PST Sorry if my question doesnt make sense. But our continents are moving slowly apart from each other, if I recall. So wouldnt they eventually meet? Would they collide into each other or just sorta combine? If they collide would it be like an earthquake? [link] [comments]  |
| Why does the blood flow in the brain have a different Reynolds number than the aorta? Posted: 09 Nov 2018 07:37 AM PST Hi ! I was reading the wikipedia article on Reynolds number and came across the fact that the typical Reynolds number for blood flow for the brain is a factor of 10 smaller than the Re for the aorta, could anyone give a short explanation of what it means and why exactly there's such a big difference? Thank you in advance ! [link] [comments]  |
| Why is it called an α-1,β-2 glycosidic linkage? Posted: 09 Nov 2018 09:52 PM PST My professor told me that it was called an α-1,β-2 glycosidic linkage because the oxygen is between the 1' carbon on the α-D-Glucose molecule and the 2' carbon on the β-D-Glucose, but as it seems in this diagram, the oxygen is between the 1' carbon on both molecules. What am I missing? [link] [comments]  |

| Do people born blind have 3D good spatio-temporal intuition? Posted: 09 Nov 2018 08:38 AM PST I come from Machine Learning with a neuroscience-y question. Basically, some models that we train to interact with an environment often benefit from a good amount of "Newtonian" and causal priors. Very often, these priors are embedded in the visual system of the Machine Learning model, as priors over local displacements, or as visual contingency awareness. Doing so in the visual domain is often much easier than in an abstract domain. This made me wonder if we have clues as to whether our brains really require vision in order to learn such things or if we have a "signal-type-agnostic" learning mechanism that just learns about intuitive physics. This led me to wonder if blind people lack some spatio-temporal intuition that non-blind people have, or if vision is a required ingredient for some class of physical reasoning tasks. Thanks!

| Posted: 09 Nov 2018 05:22 AM PST I was wondering what the best way to take notes is and I wanted to know if there was any scientific backing in the most optimal form of note taking. [link] [comments]  |
| In what way is spin related to the standard model? Posted: 09 Nov 2018 09:29 AM PST And how come the bosons have 1 as spin number and the fermions 1/2? [link] [comments]  |
| Could gerrymandering be improved if you forced every district drawn on a map to be a quadrilaterial? Posted: 09 Nov 2018 07:27 AM PST Obviously it'd be better if we could just have an algorithm draw the districts. But could something like this be a simple bandaid to solve problems like Illinois's 4th congressional district? [link] [comments]  |
| Do we have any idea what our solar system's previous star was like? Posted: 09 Nov 2018 09:31 AM PST I've read our sun and planets formed from the remnants of an exploded star that was here before. Can we tell anything about it from the material composition of our solar system? [link] [comments]  |
| Why don't whales have a high risk of cancer if they have a large amount of cells? Posted: 09 Nov 2018 02:56 AM PST It makes sense. Whales have more cells than most animals so they must have a high risk of cancer. But they don't. If not. Less than humans as they live much longer. Why is that? [link] [comments]  |
| How is the Earth affected by other planets orbits? Posted: 09 Nov 2018 07:36 AM PST As planets orbit the sun, how does it affect the Earth as other planets come "close"? [link] [comments]  |
