Why is Noether's theorem considered one of the most beautiful in physics? Posted: 07 Aug 2017 06:18 AM PDT I believe I understand it and what it means -- every differential mode of symmetry must have an associated conservation law -- but I guess it fails to strike me in the same way it strikes others. Is this just a personal thing, or am I missing something? submitted by /u/haha_mcat_xD_lol [link] [comments]

What is the brightest light on Earth? Posted: 07 Aug 2017 04:56 AM PDT Hello reddit, I just saw another space post by someone on the ISS. Some areas on earth at night are obviously brighter than others due to being clusters of lights in cities. I now wonder, what light on Earth is the most noticeable from space.

What shape is the universe? Posted: 06 Aug 2017 05:14 PM PDT I had a very strange thought come to my head today. The earth is round, correct? Well what if (not saying it is) the universe was round? I know that everyone says it's endless but if the universe was round in "shape" then that could mean it's in its own form of galaxy!

Has there been an optimal design for a fan or fan blade created yet? If so, Why isn't it used in every application that requires a fan? Posted: 05 Aug 2017 08:05 AM PDT Hi, The question originates from seeing various designs for fans in general with varying degrees of air flow per speed and efficiency. I was looking at computer fans, ceiling fans, car radiator fans, windmills, AC fans, and more. I got to thinking that the design with the most air movement would find it's way as the defacto fan blade design standard and would be used in every application. Yet even in some applications as trivial as CPU/GPU coolers in computers we find fans with varying curvatures, angles, and gimmicks. Am I wrong for thinking that the most optimal design would/could/should be used everywhere with the only difference being speed to control the airflow (CFM)? Has it already been made and is it being held up by a patent somewhere? Sorry in advance, This has just been my shower thought for a few weeks and I haven't found any sufficient Google answers for it. submitted by /u/bintu [link] [comments]

Why do 'fast' neutrons need to be moderated in a uranium reactor, but not in a fission bomb? Posted: 05 Aug 2017 01:37 PM PDT Nuclear reactors use a moderator to slow 'fast' neutrons down to the point where they are likely to be captured by a U235 nucleus. But when you slam two pieces of weapon-grade uranium together, it doesn't require a moderator to make them explode. The high-energy neutrons seem to be absorbed just fine. Why? submitted by /u/mediacrawdad [link] [comments]

Does smoke from a wildfire lower temperature in surrounding areas? Posted: 04 Aug 2017 06:32 PM PDT Living in British Columbia and with the current wildfires that are going on, does the smoke somewhat cool the area? On Wednesday and Thursday, the forecast predicted the temperature to be nearly 100F but felt like mid-high 80s instead. Where I live is currently engulfed from the smoke.

What are the effects of alcohol on human brain development on people ages 18-24? Posted: 04 Aug 2017 09:18 PM PDT As a college student, I watch a lot of binge drinking and I've gone to my share of parties too. I've heard a lot through school about how alcohol stunts development in young people. To what degree is this true, especially in the young adult age group where people are mostly done developing physically. How much do different levels of drinking harm different age groups? (A few drinks every weekend vs once a month vs heavy regular binge drinking). I feel like there are a lot of biased answers on this topic so I'd love to see your sources! submitted by /u/searchandrescuespoon [link] [comments]

Is there such a thing as absolute electric potential? Posted: 05 Aug 2017 06:37 AM PDT let's say I have three metal plates, let's call them A B C, and a voltage source. I put A and B very very close to each other, and I use the voltage source to charge them like a capacitor, let's say A is positive. Then I remove the source and separate the plates. What are the potential differences between A and B and C? C's potential is 'unchanged' from its ground state. Is there some absolute potential (let's say zero?) that I can assign to it? Does this mean the B is negatively charged in some absolute sense? At this point I have a slightly positive A and a slightly negative B...

Why is water compressible? Posted: 05 Aug 2017 04:13 AM PDT The general assumption is that water is incompressible.

What impact do coffins and embalming have on the earth instead of decomposition? Posted: 04 Aug 2017 10:09 AM PDT According to the ecology global network, 55.3 million people die every year. I haven't found any numbers regarding coffins, but I am imagine that many people use some method of embalming or preservation when they die. I also have to imagine that a body decaying naturally in the earth has much more nutritional, beneficial properties for the earth than a body sealed in a box or one that is embalmed. I might be asking this question in the wrong manner, if so I apologize. My primary interest in this question regarded the current state of the earth. Whether or not global warming or just about anything can or could be altered by this coffin phenomena. submitted by /u/winnercakesall [link] [comments]

How do we know that the Universe's law or constants never change? Posted: 04 Aug 2017 12:04 PM PDT If all we know is from comparing the universe against itself, how can we actually know that our various discoveries on how the universe operate can't ever change? It goes against human instinct for sure, but has science actually proven that the universe isn't able to change itself? And since theories that the universe might be a computer simulation are becoming popular I feel this question is becoming even more relevant. In that case anyone outside the simulation could change the constants (for example, alter the speed of light slightly) at any time. But even outside easy-to-imagine ways in which the universe could have its constants changed, has science ever backed up the nearly-universal assumption that these constants couldn't change? submitted by /u/lacertasomnium [link] [comments]

How do the antibodies in a blood donors blood behave in the blood recipients body? Posted: 04 Aug 2017 02:51 PM PDT So obviously blood type is selected against the antibody response of a recipient using the ABO+/- system, therefore the donor must be screened for antigens that could induce an antibody response in the recipient. My question is what about the antibodies present in the donor blood? My intuition is that isolation from its origin lymphatic system blocks the antibodies from initiating any significant response as the recipients immune system could possibly be unresponse to the foreign antibodies. With that being said, certainly some free floating donor antibodies must react with the antigens in the recipient when receiving the blood. Does this simply occur in a negligible quantity without the lymphatic memory response to proliferate the defense? An example being an AB recipient receiving O blood ought to trigger a double rejection by the donor bloods limited antibodies to the recipients system, similar to if an O recipient received AB donor blood. submitted by /u/robindawilliams [link] [comments]

How high up the atmosphere can Carbon Dioxide go? Posted: 04 Aug 2017 03:39 PM PDT School Books taught me that Carbon Dioxide create a barrier of some form that keeps heat from leaving the planet.

How much do we know about the physical properties of different antimatter? Posted: 04 Aug 2017 12:42 PM PDT I was reading about anti-hydrogen.

What would happen to a rocket if it launched straight up and didn't turn sideways? Posted: 04 Aug 2017 08:22 PM PDT I understand that rockets turn sideways a bit after they are above most of the atmosphere to gain orbital speed, but what if it didn't turn? I assume that the rocket can still get to space just from sheer thrust. If it kept going and stopped around the ISS orbit, would it just fall back or start to orbit? submitted by /u/lordDAmaster [link] [comments]
