| [Mathematics] How can I store multiple integers as a single value? Posted: 04 Dec 2017 08:46 AM PST So I'm a programmer and I had a thought. There are functions I can use to store a value between program states, but I can't store a list of values. If I have 2, 8 and 15 and I want to carry them between states, I'd have to store 3 values, but is there a way to use a calculation that I could reverse that would produce a single number, so I could get the values back after? I could store 2, 5 and 7 as 257 and have the program decipher it to return 2, 5 and 7 but that only works for single digit integers, and long lists would produce a number too large. The use of primes comes to mind but im unsure how, or if it's possible. Ideas? [link] [comments]  |
| How can migranes hurt if you have no pain receptors in your Brain? Posted: 04 Dec 2017 04:41 AM PST I have heard from several sources, including my Biology Teacher, that the brain lacks pain receptors, even going so far that you could perform brain surgery on a patient without anesthetics. I have also read on Wikipedia, that often, migrane is caused by an arthery in your brain expanding to a certain degree (which seems reasonable, as migrane often feels like pulsating pressure in the brain to me). But how can you feel that pulsating pain, if the brain itself is inept of feeling direct pain? (Please note that I have very little knowledge of medicine, but am but a humble fool who often has migranes.) [link] [comments]  |

| Are there any genes found in dogs that aren't found in wolves? Posted: 04 Dec 2017 07:15 PM PST I am curious as to whether there are genes in dogs that aren't found in wolves. I know E. coli developed a new citrate-metabolizing gene after about 33,000 generations, and there have probably been about half that many doggy generations since they were domesticated ~14,000 years ago (my numbers may be off). I also know that short-legged breeds have a gene analogous to achondroplasia, but I don't know if that's found in wolves or if it's from a mutation or what. So, are there any genes found in genetic screening of dogs that aren't found in wolf genomes? [link] [comments]  |

| How can a device such as a phone 'resist' being charged if it plugged in and connected to power? Posted: 05 Dec 2017 03:12 AM PST In regards to an incompatible cable or a power source with not enough volts - if is connected to power, how can a device 'decide' not to charge? Is the electricity grounded somehow? [link] [comments]  |
| How are molecular sieves manufactured? Posted: 05 Dec 2017 12:07 AM PST You know, those little balls you toss in whatever you want to dry 'cause they have ~3 Angstrom holes to absorb small molecules like water. How the hell do you make them at an industrial scale? [link] [comments]  |
| Does a USB-C - USB-C charger extension cord slow down the charge? Posted: 05 Dec 2017 07:20 AM PST DEVICE -> EXTENSION -> charger -> wall hub -> wall outlet. Will this make it a slower charge than the normal DEVICE -> charger -> wall hub -> wall outlet? If so, why? Does the length cause it to draw slower or less power? For the sake of purpose, I'm referring to USB-C TO USB-C only as I read USB-A it does effect the charge. [link] [comments]  |
| How do particle accelerators sync with the particles? Posted: 05 Dec 2017 03:11 AM PST When a particle accelerator like CERN is accelerating a particle how do they time the RF Cavities with the particle? Should I change this to the engineering category? [link] [comments]  |

| I saw an intensely green meteor shoot across the sky. Why was it green, and how common are they? Posted: 05 Dec 2017 06:49 AM PST Additionally it had a very flat trajectory and flew slightly slower and farther than most other meteors I've seen. Color reminiscent of bioluminescent plankton, or the green hues of an aurora. First time I've ever seen one, it was very beautiful. Thank you! [link] [comments]  |

| What is the science behind emotions? Is there a scientific explanation for them? Posted: 04 Dec 2017 08:13 AM PST Seeing that we only feel them and can't physically touch them, I'm wondering if there can be a science behind it all. [link] [comments]  |

| Why does the SpaceX Dragon V2's Trunk have winglets on it? Posted: 05 Dec 2017 05:54 AM PST I noticed that there are small solar panels on the winglet, but in space, where there aren't too aerodynamic forces on the vehicle, why does the Dragon V2 have small winglets/stabilizers? Is it for stabilization because the vehicle doesn't have fairings on liftoff? [link] [comments]  |
| Does electron/positron annihilation leave the first atom charged? Posted: 05 Dec 2017 02:07 AM PST For example, an atom (A) undergoes beta plus decay, the emitted positron annhilates with an electron from atom (B). If atom B had a charge of 0 before, would it now be +1? [link] [comments]  |

| Why is pyrite not an economically viable metal ore, but other sulfides are? Posted: 04 Dec 2017 03:01 PM PST I understand the basics of why pyrite isn't used as ore - it's difficult (and therefore expensive) to extract, and even when done correctly the result is still poor quality iron contaminated with sulfur. But why is this the case with pyrite, but not so with other sulfide ores like chalcopyrite and galena? Do they also have the same problem, it's just that we rely on iron for its mechanical strength far more than metals like copper, and therefore it's "acceptable" for a bit of sulfur contamination? What's the specific nature of the bond between iron and sulfide that makes the sulfur so "sticky" compared to the more economical iron ores, hematite and magnetite, which are oxides?

| Can Tritium beta expose photographic film? Posted: 04 Dec 2017 01:28 PM PST Is the tritium beta particle capable of "exposing" photographic film? I know that many radioactive materials, placed in contact with photographic film can, over time, generate an "image" which can be developed, but is the beta particle from tritium capable of doing this or is it too low energy? How much energy is needed to expose photographic film? [link] [comments]  |
| What's the difference between dipole and coaxial? Posted: 05 Dec 2017 04:20 AM PST I'm finding a fm antenna for my old yamaha Rx-V665 stereo receiver. https://www.amazon.com/Fancasee-Antenna-Coaxial-Yamaha-Receiver/dp/B074QLLVC6/ref=sr_1_26?s=audio-video-accessories&ie=UTF8&qid=1509974334&sr=1-26&keywords=fm+antenna Can it get signal in inclosed basement?
