| How can I obtain ethanol 100% if at 95.4% is considered an azeotrope? Posted: 13 Nov 2016 11:59 AM PST I am currently in my thermodynamics class and was introduce to the term of azeotropics mixtures, and learned that ethanol 95% is considered one, my question therefore is if we can by other procedures other than distillation we can obtain ethanol 100%. Sorry for the poor grammar. [link] [comments]  |
| Posted: 13 Nov 2016 02:46 PM PST I think that I understand the superposition principle but I don't understand how can a quantum system can use it to explore more combination of qbit at once. For example factorisation ? [link] [comments]  |

| Does radioactive decay of an atom cause significant changes in the properties of chemical compounds? Posted: 14 Nov 2016 05:24 AM PST I am not asking about the radiation, what I mean is, for instance if F-18, used in Pet scans, decays to oxygen-18, the resulting oxygen will be unsaturated. Will it immediately react with another molecule in its surroundings? What about metals in organometallic complexes, will they instantly change configuration if the new metal center is unstable in the old one? [link] [comments]  |
| What is the significance of Mochizuki's ABC Conjecture? Posted: 13 Nov 2016 10:11 AM PST As someone who does not have a backing in hard mathematics, is there a wildly simplified version of what the abc conjecture is/and does for mathematics? [link] [comments]  |
| Posted: 13 Nov 2016 07:28 PM PST Like will a soft cap, where research has gone so far that it takes a lifetime to catch up, ever occur? Will we avoid this by specializing kids after they have learned all they need to research? Because eventually, it will take an immense amount of time to learn what you need to know to research, right? [link] [comments]  |

| What causes the smoke/dust unsettling during a nuclear detention? (Before the shock wave) Posted: 14 Nov 2016 02:21 AM PST If you watch videos of tests, you will see what looks like smoke or dust rising from structures before the blast actually hits. What causes that? Is it just the heat from the detention? Video for Reference (Courtesy of AtomCentral): https://youtu.be/ztJXZjIp8OA?t=16s [link] [comments]  |
| Qantum physics seems contradictory to wave functions in the photo electric effect, why? Posted: 14 Nov 2016 06:03 AM PST So the question is, if photons actually exists in a form of a wave function, why cant they combine or positively interfere as to give rise to one larger energy state? In the photo electric effect which we know is because of quantum physics, we could bombard a photo electric cell with intense lasers of a wavelength where the photons dont combine into an energy state with which it could knock an electron free, shouldnt this happen if photons actually existed in some form we would mathematically call a wave function. Or am i just too ignorant of what is actually going on here? Some answers would be very welcome. [link] [comments]  |
| Can we reasonably certain that laws of physics don't change over space and/or time? Posted: 13 Nov 2016 07:39 PM PST It seems innocent enough to assume that the laws don't change but isn't that a very big assumption with far reaching consequences? Can we test this? It may be possible that small changes add up when we look very far in space and time like peering back into the moments after the big bang. Do have instruments sensitive enough over our small time and distance scales to rule out that this might be happening? [link] [comments]  |
| Why is there an electric field in a PN junction? Posted: 13 Nov 2016 01:01 PM PST Hi! I am really puzzled and feel like I am missing something concerning the structure of a P-N junction. When I look at this image I see the unaffected parts (away from the junction) in both types of semiconductors labeled as "neutral". I don't get it. Shouldn't the P semiconductor have positive overall charge thanks to a larger number of holes to electrons and vice versa for the N type (having more electrons than holes making it over all negative)? Furthermore, when they form the junction, physical electrons from the N type should flow to the now available holes in the P type. Number of electrons in the N part of the junction decreases, lowering the overall negative charge and it feel like it should have neutral charge then? And on the P side, the excess number of holes gets filled by electrons, lowering the amount of positive charge and make it neutral, right? Then how comes that there is a positive charge on the N side and negative charge on the P side, as depicted on the picture, forming the electric field that prevents further diffusion of particles between the two parts. I am really confused by this and would love to understand what am I missing here. Thanks and sorry for my English, not a native! :) [link] [comments]  |
| Posted: 13 Nov 2016 09:08 PM PST Was just curious how likely it could be. If there were to be two separate starts of life in one solar system then life should be abundant across the solar system. [link] [comments]  |
| Can memory "degrade" from lack of use, similar to how a muscle will atrophy if not used? Posted: 13 Nov 2016 06:21 PM PST Both long and short term memory. Say if you were in a long term (5+ years) situation where...you just weren't really required to remember anything on a daily basis, weather important or minimal. If so, is there any way of "working out" your memory to get it back? Can concentration be tied to this? Thanks :) [link] [comments]  |
| Is it possible to prove that any given number is irrational? Posted: 13 Nov 2016 08:29 PM PST I've seen proofs that √2 and other square roots are irrational; but its there a generalized way in which you can take a given number and know if it's irrational? Also, if you add two irrational numbers, is the result irrational? What if you multiply, or do any operation, do they behave in a predictable manner? [link] [comments]  |
| Does the velocity of its source influence the direction of light? Posted: 14 Nov 2016 02:20 AM PST Say you are in a room without gravity, and you are moving upwards on an elevator at V_e = (0,1). (By 1 m/s in Y direction). You throw a ball forwards, in X direction, at velocity v_b = (1, 0). To a coordinate system fixed on the floor, the ball would be moving at V_b = (1,1). If the elevator stops at the moment just after you have thrown the ball, the ball would then be moving at V_b = (1,1) relative to you. When it hits a wall at some distance, it will be higher than the elevator. Visually: If light were moving at a much lower speed so you can see the difference, and you would emit a pulse of light instead of a ball, would the pulse of light still end up at a higher location on the wall (B), or would it end up in front of you (A)?

| Possible explanation of a cross section of a bound-free transition of a 1s Hydrogen-like atom? Posted: 14 Nov 2016 01:06 AM PST Had to solve a problem including concepts such as: overlap integrals regarding two wavefunctions, dipole moment matrix element, and Fermi's golden rule to find this cross section. Here is a link to the specific problem. I understand the concept of wavefunctions, what all the variables mean, etc. But I become lost when it is introduced into the dipole moment matrix, and subsequently Fermi's Golden Rule. Would somebody be able to breakdown these concepts for me a bit? I was able to somewhat figure out the problem and got a mathematical answer, but I didn't know entirely what I was doing (i.e. my math felt empty, so to say). [link] [comments]  |
| What sort of lab/equipment is used to study quantum entanglement of particles? Posted: 14 Nov 2016 12:33 AM PST I'm working on a short film that involves a bit of pseudoscience where the main character discovers how to entangle particles. It's not going to be 100% accurate by any means, but I'd like to at least make it somewhat believable. [link] [comments]  |

| How loud of a sound could occur within Earth's atmosphere? Posted: 13 Nov 2016 05:12 PM PST Assuming an average density of molecules in the atmosphere of Earth, how loud of a sound could there be? Sound is a release of energy. Energy can rip apart atoms. Ipso-facto, how loud could a sound be before it rips apart the atoms of the medium it is travelling through (in this case the atmosphere)? And would the atoms being torn apart be enough to stop the sound from travelling? [link] [comments]  |

| Is it possible for a deaf person to have tinnitus? Posted: 13 Nov 2016 02:51 PM PST I was wondering because it's not actual sound, but rather the perception of sound that is what causes the ringing sound so I was wondering if deaf people have to deal with this ever, or is it not possible?
