| How do some elements group together underground? Posted: 11 Jan 2018 04:32 AM PST If most elements are created during supernovas you would think that they would be uniformly scattered around. Then why is it some elements (gold, tin, copper etc) seem to be grouped together underground? [link] [comments]  |

| Where does the energy come from when matter/antimatter interacts? Posted: 11 Jan 2018 04:07 AM PST An enormous amount of energy is released when matter and antimatter annihilate each other...Why is that? How is the energy formed? [link] [comments]  |
| Posted: 10 Jan 2018 07:08 PM PST Say you have two objects at a locked distance from each other, A and B. Each object launches something at the other one at the speed of light, objects X and Y. What is the speed of X relative to Y? [link] [comments]  |

| Is it possible to create heavier hydrogen isotopes? Posted: 11 Jan 2018 12:26 AM PST I know we have three hydrogen isotopes: regular hydrogen, deuterium and tritium. Is it possible to add another neutron to tritium and create even heavier isotope? Or is there some limit how many neutrons can one proton bind? Maybe this next isotope exists but is too unstable and decays almost instantly, and that's why we don't hear about it? [link] [comments]  |
| Why or How stimulated emission works? Posted: 10 Jan 2018 11:35 PM PST Hello there, I'm an electronic engineering student at Roma tre University and I need your help. In today photonics' class we discussed about laser why they emit and how; I cannot understand the reason why stimulated emission work. We know that an atom, or an electron, at a certain energy level when it's hit by a photon with the right energy it changes its state; in stimulated emission what occurs is that the atom (on level say E2) is hit by a photon with a certain energy (E2-E1)and emits the same photon and then decades emitting another photon of the same kind. I don't understand why it's possible such a thing, I would expect just e reemission of the incident photon because the atom can't stay there but neither go higher. Thanks for you help!

| I can use a wave function to calculate probability, but what does the function mean? Posted: 10 Jan 2018 03:30 PM PST Do the real and complex parts mean anything by themselves? Or let's say you have 2 parameterized wave functions. One of them has magnitude r(x) and direction f(x), and the other has magnitude r(x) and direction g(x). They have the same magnitude parameter, so they agree on the probabilities of a particle appearing at every point of space. But do f(x) and g(x) mean something? If I had to guess, momentum is some function of the direction parameter, but I don't really have anything to back that up except it's all aesthetic and symmetrical. Thanks! [link] [comments]  |
| Posted: 10 Jan 2018 09:13 AM PST A friend of mine is over 65 and is concerned about the news reports that this year's flu is "especially deadly". While I understand that the elderly are always at risk, in what way is this year's flu more deadly? Is there something inherent about the flu this year (other than the problems with the vaccine) that makes it worse than other years? [link] [comments]  |
| When was the sonic boom discovered? What was the general population's reaction? Posted: 10 Jan 2018 07:45 AM PST Considering how the common man loses his mind with the unknown, I was trying to imagine the news reports and reactions to the first sonic boom. [link] [comments]  |
| Can nerve endings get fatigued? Posted: 10 Jan 2018 08:43 AM PST If nerve endings were to get over-stimulated possibly over a prolonged period of time is there any way they could become 'tired,' 'fatigued' or less effective either short term or permanently? [link] [comments]  |
| Why haven’t we come up with a better solution for Telephone Poles/Wires? Posted: 10 Jan 2018 02:52 PM PST Telephone poles/wires are pretty unglamorous and take up a lot of the visual real estate in a town, neighborhood etc. I've seen a lot of campaigns to removing them—so why haven't we replaced them? And what's being done for new development areas? [link] [comments]  |
