[Physics] What makes the continuous stream of bubbles from a single spot when you pour champagne/highly carbonated beverages?

Direction of a photon? Posted: 17 Jul 2017 01:57 AM PDT Imagine you have an atom that gets excited and releases a photon. How is the direction of this photon decided and how is the energy transferred? If it is actually a wave that emits from the atom A (imagine an expanding shell of a sphere with energy of 1 quanta ) at some point this sphere interacts with another atom (B) to excite that. I've got some crazy ideas which are probably not sensible but it's fun to take guesses based on limited knowledge :) All the energy in that sphere emitted by A is now absorbed by B so not other atoms in any direction will be excited by that shell. This seems bizarre since I'm not sure how a directional laser can work in this setup. All atoms in the universe have a chance of being excited by that photon shell but based on probability where the closer it is to A the more likely the chance. The probability is also multiplied by the crossproduct of the A->B vector and the vector the photon wave is emitted from. This would seem to explain how lasers can work and distant starlight but would probably mean time isn't discrete but more an integral between observations? Would also seem indicate everything is simply connected with time delays rather than light actually travelling through space. Would love someone to help better understand what is going on here... submitted by /u/5tu [link] [comments]

How did engineers manage to do calculations and modelling pre GUI PCs? Posted: 17 Jul 2017 02:54 AM PDT Hi! I was just watching the SR 71 speed check video and it reminded me of an episode in "The Americans" in which soviet scientists want to get a hand on the design (The cross-section, I think it was called?) of a plane the US is designing. My question is: How did scientists and engineers at said time (Late 70's, early 80's) model air/turbulences/pressure without the GUI we have today? I know from a friend who is studying mech.eng that software like MathLab allows you to simulate, via FEM, said situations. I saw one of his homeworks and it was a steel beam with different colors showing different pressure points and where it would break/bend. However, without this visualization, how do you read the results? Is it like a partial derivative? Ie: You have numbers for each "slice" in the digital mock-up? I have tried to find an answer for this before writing the question but either there is none or I missed the right keywords. If you already know a link explaining this, I would be more than glad to read it. submitted by /u/Megustoelbertolucci [link] [comments]

[Physics] What is the amplitude of a light wave? Posted: 17 Jul 2017 06:58 AM PDT So the amplitude of a sound wave is the difference in pressure caused by the sound wave, and the intensity of the wave is just the power of the wave. For the case of light, the intensity is equivalent to the number of photons per second, but what is the physical representation of its amplitude? submitted by /u/lalaland296 [link] [comments]

Is it possible that not only space is expanding, but time as well? Posted: 16 Jul 2017 06:16 AM PDT Could you provide reasons or sources, if you think just space is expanding and time is unable to? Related questions: If we can't reach some space regions because space expanding, is it possible we also can't reach some time regions because of time expanding (e.g. the end of universe)? Could we measure time expansion? e.g by observing far away objects like Cosmic Microwave Background, distant galaxies, or pulsars? submitted by /u/sheerun [link] [comments]

What makes meat taste gamey? Posted: 16 Jul 2017 10:01 PM PDT I hate gamey meat. I struggle eating lamb, and I can't even get near goat just from the smell alone. I generally don't think of myself as a picky eater, so I'm wondering if there's like one specific chemical or something in gamey meat that I'm extra sensitive to. I was reading an article that compared gamey meat to the taste of liver. I don't think this applies to me, though, because I love the taste of liver. Gamey meat has a distinct, singular taste that I can't quite describe but I recognize it instantly if I eat or smell something gamey. submitted by /u/heavyLobster [link] [comments]

Are there any fluids whose viscosity doesn't change with temperature? Posted: 16 Jul 2017 06:24 AM PDT I've just started to learn fluid dynamics, and was surprised to find that liquid viscosity decreases with increasing temperature, while gas viscosity increases with increasing temperature. It makes sense, but it makes me wonder if anything has a viscosity that doesn't vary, or has a maximum/minimum viscosity at a certain temperature. It looks like superfluids would have a constant viscosity? What about other substances with non-zero viscosity? submitted by /u/994phij [link] [comments]

How can scientists predict there will be a "megaquake" off the coast of North America? Posted: 16 Jul 2017 03:31 AM PDT I'm currently watching the National Geographic show Disaster Earth and this episode is about earth quakes. They say that sometime in the future, there will be an earthquake comparable to one on Sumatra in 2004 and Chile in 2010. They say the cities of Portland, Vancouver and Seattle are at risk and as many as 4 per 1000 people living in the area will die, comparing that to the fatalities of the second world war.

Twin paradox without the turn? Posted: 15 Jul 2017 10:19 AM PDT Hey! So, the twin paradox normally goes - a space ship flies away from earth, then comes back. However, because the space ship turns around or something, you can plot the world lines on that funny graph and it turns out they lost some time due to length contraction or something blah blah. How about if the space ship started really far away, moving towards the earth? Say the observer on earth saw people inside the space ship age at twice the rate. The people on the space ship would also see the people on earth age at twice the rate, right? How does this get resolved, over a period of time both parties observe themselves aging half as fast as the other, what age are they when they meet? Am I just getting it muddled in my head? Thanks! submitted by /u/ipe369 [link] [comments]

Is there evidence surgical masks being worn by people who are ill significantly help limit infection of others? Posted: 15 Jul 2017 06:57 AM PDT I know this is common practice in Asia and, particularly in places with high population density and in tight public quarters it makes sense, but is there evidence this significantly helps reduce infection rates, or is this mostly an old wives' tale? submitted by /u/polishprocessors [link] [comments]

Ionization by nonuniform magnetic field possible? Posted: 15 Jul 2017 03:06 PM PDT When including spin-magnetic field interaction in the Hamiltonian with the term B * S, e.g. B=(0,C*y,0), B_y * S_y=C * y * σ_y and using r + spherical harmonics for y. Does it mean an electron can escape from a bound state into the continuum (ionization) while having a spin flip through magnetic field interaction? Usual sources are not clear about whether this is possible, but the transition matrix element shouldn't be zero between a final (Coulomb-like) and initial (bound state) wavefunction. Even electron momentum l should be able to change in a transition like this. submitted by /u/tuxintuxedo [link] [comments]

Why is feedforward system in active noise control being susceptible to wind noise a disadvantage? Posted: 15 Jul 2017 09:02 PM PDT I was reading this article (http://edn.com/design/consumer/4422370/Active-noise-cancellation--Trends--concepts--and-technical-challenges) and it says that the feedforward system has a disadvantage of being susceptible to wind noise.

Does ivy actually hurt a tree by "choking" it, or is that an old myth? Posted: 15 Jul 2017 06:57 AM PDT I recently bought a house that has ivy on some of the trees in the yard. I was surprised by the number of conflicting "facts" I received during the inspection period. Landscapers, inspectors, friends, relatives, etc. each had a different opinion on whether ivy is bad for a tree. Some say that, without exception, it "chokes" the tree and kills it slowly. Some say there's absolutely no problem so long as the ivy leaves aren't blocking the tree's leaves. I was told "see, the ivy is why the to isn't growing," as well as "see, the ivy is why only the top can grow," and on and on and on. The homeowners said it had been growing in the trees when they bought it years ago, and the trees never showed a problem. I looked online and found a couple of sciencey looking articles that said it's no big deal, but I figure I probably shouldn't let confirmation bias be my guide. So: is ivy on a tree harmful to the tree? If so, in what conditions? Does it vary by type of tree? Type of ivy? What else do I need to know? What sources can I site to shutdown the disbelievers? submitted by /u/JeffnKaye [link] [comments]

What happens if a quantum entangled particle B is sent through a BBO again? Posted: 15 Jul 2017 03:17 AM PDT (I'm just a curious noobie asking questions :-) ) Shooting a photon beam into a nonlinear crystal (BBO) is a method (SPDC) of creating two streams of quantum entangled photon pairs in superposition. The first stream of particles is called stream A, the second stream is stream B. What happens if the second stream is directed into a second BBO crystal again and one obtains two new streams of B1 & B2 particle pairs? are these photon pairs (B1 & B2) in super-superposition ? how is this measured in Bell tests of the streams of particle pairs B1 & B2? or was a 'state collapse' forced onto the photon B before it was split into B1 & B2? If option 1 is valid: do the Bell test results of the streams of B1 and B2 particles change if the particles in stream A are measured first? (likely not, correct?) I am quessing the Bell test results of the B1 & B2 pairs must be unchanged, and that means all B photons were forced into a state collapse, correct ... ? Is there any type of experiment that creates a super-superposition ?? ( ... GHZ?) submitted by /u/physicsschmysics22 [link] [comments]

Does what my mother ate while she was pregnant with me effect what I like/don't like to eat? Posted: 14 Jul 2017 08:35 AM PDT When my mum was pregnant with me she ate a lot of oysters (and I mean A LOT - like several dozens a day, most days). I personally find oysters to be gag-inducingly foul without exception, always have. Whenever I've mentioned this to my friends they often seem to have an especially hated food that their mother craved a lot during pregnancy.

Are there any new emerging fields of mathematics? Posted: 14 Jul 2017 10:36 AM PDT Some scientists say, that we don't understand fully quantum mechanics, because the math we need to solve some problems isn't even invented. Are there any papers or proposals on fundamentally "new" mathematic fields, which are emerging? From my knowledge lie-groups, grouptheory and probabilistic theory were the last big areas in mathematics, which were invented (correct me if i'm wrong). And by "new" I just mean: inherently different from the approach on solving some problems. P.S.: I know this question can trigger some mathematicians, because I may oversimplify some things. Sorry for my lack of knowledge. submitted by /u/ManagerOfLove [link] [comments]

Is water truly uncompressable? Posted: 14 Jul 2017 09:12 PM PDT I've heard so often that liquid water cannot be compressed, but is it really impossible? I've searched the topic and the results all seem to refer to it not being practically possible. But under hypothetical circumstances, say extreme gravity in the core of a planet or something, would it compress? If possible, my best guess would be that it becomes ice, only really hot. submitted by /u/merger3 [link] [comments]

Won't Juno's final plummet to Jupiter's surface be the most rewarding opportunity of the entire mission to collect pictures and data? Posted: 14 Jul 2017 06:43 PM PDT This last section of Business Insider's article on Juno's findings mentions, Juno won't fly forever. NASA plans to plunge the spacecraft into Jupiter's clouds in 2018 or 2019. This will prevent the probe from spreading any bacteria from Earth to the gas giant's icy, ocean-filled moons like Europa and Ganymede. Won't the final plunge into Jupiter be the best opportunity to collect images and other data since it'll be Juno's closest (and last) encounter with the planet? I do understand the probe may not be able to stand up to the forces of entry into the atmosphere and therefore won't be able to collect data from then on (correct me if that's wrong), but up until entry will Juno still be collecting information? Links and other knowledge of this will be greatly appreciated, and please keep vocabulary and other jargon to the basics please! submitted by /u/Umbross13 [link] [comments]

Posted: 14 Jul 2017 08:04 AM PDT I'm not an expert or a psychologist, but the way we talk about pathology is different than the way we talk about autism. There are people with autism we call functional. There are people with autism who need a lot of outside help. Is it the same for anti-social disorders? Are there people with small amounts of psychopathy? What about ones that don't commit full on murder spree but they do leverage economic power for their personal gain?

Posted: 14 Jul 2017 07:46 AM PDT Currently I'm 22 and have grown out of my asthma so I only have an emergency albuterol inhaler for if I get a cold or the flu, which is the only time my asthma ever bothers me now. As a kid growing up in New England though, the winters were the absolute worst for me. Those cold months would be riddled with asthma attacks, however in the summer I would rarely if ever have an attack unless brought on by strenuous physical activity. I've always been very intrigued by medical science and I remember reading somewhere that in the early 20th century doctors would bring patients with severe lung related ailments to the American Southwest because it was hot, dry, and largely unaffected by industrial pollution at the time. So I was wondering if there were any areas like the Southwest U.S. or just any populations at all that are completely free of asthma? submitted by /u/peanutbudderbacon [link] [comments]

What happens after you accidentally carry a bee to a new place in your car... Does it find a new new hive to join or continue independently or just die? Posted: 14 Jul 2017 09:49 AM PDT submitted by /u/RoryPond11 [link] [comments]

How does the anisotropy/transmission axis of polarizers work? Posted: 14 Jul 2017 01:48 PM PDT So polarizers have optical axis that block or let through the corresponding polarizations of light, but it also depends on how much the polarizer is rotated, like shown in Malus's Law. Somehow, the polarizer isn't the same when viewed from all direction or otherwise the light transmitted would all be the same regardless of polarizer orientation, so what is it about the polarizer that makes it have a directional dependence on light transmission? submitted by /u/yosimba2000 [link] [comments]

If a bee only feeds on plants that are poisonous to humans, will their honey also be poisonous? Posted: 14 Jul 2017 09:55 AM PDT Follow up question: How come I am not allergic to local honey despite being allergic to all the pollen in the area? submitted by /u/UnfunnyWoman [link] [comments]

Why do racecars have wide tires? Posted: 14 Jul 2017 08:46 AM PDT I recently learned that surface area does not influence the friction so why are the tires so wide? submitted by /u/Ralphyyyyyy [link] [comments]

Why does the buoyant force experienced while in water have contradictory effects on movement? Posted: 14 Jul 2017 05:12 PM PDT It's something that I've always wondered. While in a pool, we have a "lighter feeling" as though gravity affects us differently compared to being outside of water. However, this lighter feeling only seems to apply to jumping, hand stands, and vertical movements in general. When actually trying to move in water, we seem to have the opposite effect and feel "weighed down". I'm assuming it's because of the density of water, but it's still a head-scratcher as to why we feel "weighed down" with some movements and "lighter" with others- particularly horizontal vs vertical movements. submitted by /u/mannyrav [link] [comments]
