How do nuclear reactors/atomic bombs prevent a fission reaction before it is wanted? Posted: 03 Oct 2018 06:30 PM PDT I know how fission reactions work (to a certain extent atleast), but how are the neutrons contained and prevented from starting a reaction at any random point in time?

Does getting the flu shot in the US help protect you from flu virus in other countries? Posted: 04 Oct 2018 03:57 AM PDT Hi everyone, I am an American living in Germany. I will be traveling to the US in a few weeks and wondering if it makes sense to get my flu shot there. Will this protect me or are there different flu strains in different countries? From my knowledge, getting the flu shot is not common practice in Germany like it is in the US. Typically it's only for high risk patients like the elderly or pregnant women. submitted by /u/letsfiesta [link] [comments]

Does a human body emit neutrinos? Posted: 03 Oct 2018 10:08 AM PDT I read that our body emits a small amount of radiation, notably through the decay of Potassium 40 and Carbon 14. But this type of decay results in the emission of positrons, if I understand correctly. Is there another type of decay happening in our body that emits neutrinos? I wonder if our body sends small pieces of information through the universe, broadcasting our existence light-years away... submitted by /u/1-Sisyphe [link] [comments]

What is the force carrier of a magnetic field? Posted: 03 Oct 2018 07:07 AM PDT While watching a video explaining electromagnetism, it was stated that the force carrier is the photon. However, my understanding of photons is that they do not contain a charge and are therefore unaffected by magnetic fields. The video mentioned nothing of moving electrons being a force carrier within a wire. How can photons be the force carrier and yet light is unaffected by magnetic fields? What is the relationship between the nuclei of magnetic elements and the electron, if they are unified under the same force? Any clarification, simple or complex, would be greatly appreciated! submitted by /u/IanP23 [link] [comments]

what could cause a peak at 642nm in an H2 spectrum? Posted: 02 Oct 2018 07:54 PM PDT I have a hydrogen gas spectrum tube in a spectrum tube power supply. I have one end of a small bundle of fiber optic strands pointed at the spectrum tube, and the other jammed into the cuvette holder area of a PASCO spectrometer, which is communicating with an iPad via Bluetooth. The 656 nm line is supposed to be there, but I have no idea why I have a peak at 642 nm. What could produce that? spectrum here submitted by /u/mathologies [link] [comments]

Does adding more heat to a pot of boiling water make it cook things faster? Posted: 02 Oct 2018 04:45 PM PDT I have to win an argument. The idea starts off with somebody boiling a decently large sized pot of water. When small amounts of bubbles start to form and rise is what qualifies as "boiling the water". My question is, if you were to add heat and make it a rapid rolling boil, would that cook food inside of the pot faster than if the boil was less "aggressive"? An example for the food would be noodles that take up most of the space in the pot when added to the water. The person I'm arguing with says that since water boils at 100° in an ideal circumstance, the water will not (or at least nearly negligibly) cook the food faster. I think that adding more heat will make more of the water in total hotter (since I assume most of the water isnt actually at its boiling point), which will make the food hotter, which makes the food cook faster (like cooking the noodles in 6 minutes instead of 8). How does this work? submitted by /u/BoilingWaterBoy [link] [comments]

Do higher altitudes have any effect on audible pitch compared to sea level? Posted: 02 Oct 2018 04:14 PM PDT Follow up question, also what about places with high humidity? As far as music goes, unless you have perfect pitch, most people might not be able to distinguish differences since it seems relative pitch between one note to another is more important than a little deviation from a standard arbitrary root note. I figure if helium is lighter/less dense than standard air which causes pitch to go up, I didn't know if less dense air would have a similar effect and vice versa with denser more humid air if measure with a simple tuner. submitted by /u/DrBucket [link] [comments]

Do electrons truly have a non-zero probability of being anywhere in space? Do atoms have a defined size? Posted: 02 Oct 2018 07:26 PM PDT Models showing the shape of an electron orbital often show the space in which the probability of there being an electron is something like 90-95%. If this were extended not to 99% or 99.999999% but 100%, is there space in which the electron certainly won't be? submitted by /u/Chuuume [link] [comments]

What happens between the inner and outer horizons of a Reissner-Nordström black hole? And how is it connected to wormholes, white holes and/or interuniversal travel? Posted: 02 Oct 2018 07:28 AM PDT So this is the first time I'm posting around in this sub. I don't have a degree that is related to physics, maths or any other natural science in general yet I'm really interested about the abstract topics of physics such as black holes. ​ So could you guys please explain the answer of my question as if I'm retarded? I'm fine with the details, in fact I'd be happier if you went into detail and told me about Reissner-Nordström type black holes and the other types in general but I'd be so glad if you could use a pedagogic language that I could at least intuitively comprehend what the whole deal is about. submitted by /u/onatto11 [link] [comments]

Is there evidence that GR is realized with curved spaced rather than torsion or non-metricity? Posted: 02 Oct 2018 09:02 AM PDT I have heard that there are formulations of GR which use torsion or non-metricity of space and I am interested in how one would distinguish them with measurements and, as a bonus, how to imagine what non-metricity actually is. Would these different formulations potentially solve problems like dark matter or dark energy? submitted by /u/Forty__ [link] [comments]

How do you calculate the average sum of dice rolls when a "drop the lowest roll" mechanic is used? Posted: 01 Oct 2018 03:38 PM PDT In various tabletop role-playing games, game designers will often use a system to set character statistics that is some derivation of "roll an x-sided die y-times, drop the lowest z rolls, and sum up the results." The most common example of this is rolling a 6-sided dice 4 times and dropping the lowest result. Now, calculating the average sum of 3 six-sided dice rolls is simple and intuitive, yielding a result of 10.5, but when adding a 4th and dropping the lowest result, the average comes out to a (seemingly) strange irrational number of ~12.22. There are other derivations of this problem that yield other seemingly random irrational values, and while I can get to the result by writing out all the combinations and summing up the probabilities, is there a way to write this problem out algebraically? submitted by /u/TheAwsmack [link] [comments]

Can you 'russian-doll' pressure vessels, one inside another, in order to reduce the design requirements on each? Posted: 01 Oct 2018 09:12 AM PDT I work with high pressure gas infrastructure (>1000 bar) where we use very strong and very expensive pressure vessels to store the gas at high pressure. ​ A colleague came up with a 'novel' solution to this gas storage problem which in my gut I feel isn't plausible but i'm struggling to make the argument against it. I'm hoping you guys can either help me debunk it, or even prove me wrong. ​ His suggestion is as follows: Lets say you have a pressure vessel containing gas at 300 bar. You put this 300 bar pressure vessel inside a second pressure vessel which contains gas at 200 bar. And you then put THAT pressure vessel inside a third vessel containing gas at 100 bar. You now have a russian doll pressure vessel system. His theory is that each pressure vessel will need only be designed to withstand 100 bar of pressure since the delta between each layer is 100 bar. Supposedly this theory would extend to 1000 bar and beyond. ​ Purely based on theory and ignoring the practicalities of transferring gas in/out of the tanks - is this true/not true and if so, why? ​ submitted by /u/itskinner [link] [comments]

How Hard Can Water Get? Posted: 01 Oct 2018 09:53 AM PDT Everybody knows falling into water from great heights can kill you, but what is it a combination of?

Since there is no light pollution on the surface of the moon or certain comets, how come the sky isn't filled with stars and galaxies?

What stood out to me was how there doesn't appear to be any stars visible in the background of the photo. On Earth, a clear night sky with no pollution would show a ton of stars.

What causes being right/left handed? Posted: 01 Oct 2018 09:01 AM PDT Popular joke says it's amazing how many wonderful things we can do with right hand when left one just sits there and doesn't know how to hold a pencil. There are many things that we can do with left hand but not with right one though. For example if one tried to drive a nail with switched hands, not only left hand will swing uncontrollable but holding the nail with right hand feels odd too. I just tried to play guitar with switched hands and both hands had no idea what to do. Actually left hand started adapting slowly when right one couldn't hold a single string correctly. So what actually makes us "right-handed"? Does it have generic background, neurologic? Or maybe it's the way how we learn things like most children just copy what others do, but some children mirror it and therefore they're left-handed. Would child with conditions to be right-handed become left-handed when surrounded by left-handed people and child with conditions to be left-handed become right-handed in such environment? submitted by /u/KakssPL [link] [comments]

If heavier elements come from stars, where did all of the elements from earth come from? More questions as well. Posted: 02 Oct 2018 12:07 AM PDT Since heavy elements are made in stars, where did the gases come from that formed the planets of the solar system? If our star is 5 billion years old and the universe is 14 billion, how did our solar system get the various amount of elements that is has? Did another star exist exactly where ours is today that died out and left the remnants of the heavier elements? If so, how many times do you think the solar system has "reset", I guess. submitted by /u/Various_Reasons [link] [comments]

What differences are there, if any, if a person is anesthetized while sleeping instead of while awake? Posted: 01 Oct 2018 07:18 AM PDT Would one come out of the anesthesia to a sleeping state again? Would one be less confused? I've read elsewhere that less anesthetic is required, is this just for the initial anesthesia, or would the dosage through a surgery remain lower? Is it safer, more dangerous, equally risky to be anesthetized while already asleep? submitted by /u/JustLookingToHelp [link] [comments]
