| Can a computer simulation create itself inside itself? Posted: 12 Nov 2016 08:13 PM PST You know, that whole "this is all computer simulation" idea? I was wondering, are there already self replicating simulations? Specifically ones that would run themselves inside... themselves? And if not, would it be theoretically possible? I tried to look it up and I'm only getting conspiracy stuff. [link] [comments]  |
| Why does water make a rumbling sound when heated? Posted: 12 Nov 2016 09:19 AM PST Even before the water is visibly bubbling, there is a low rumbling sound. What causes this? [link] [comments]  |

| How can both nuclear fission and fusion release energy? Posted: 12 Nov 2016 05:48 PM PST I understand that nuclear fission releases energy such as a nuclear bomb. I also get that nuclear fusion such as how the sun power itself, also releases energy. How can two opposite processes both release energy? [link] [comments]  |

| What causes this effect? Is it chromastrobic light? Posted: 12 Nov 2016 02:01 PM PST At the link below, you can see at the 10th normal mode of an oscillating string, you get color production if the light from a projector shines on the string. Does this have to do with how the projector creates white light, as well as the frequencies of the string and refresh rate of the projector being close? Is this the same thing that Paul Friedlander uses in his chromastrobic light sculptures? An explanation would be fantastic. :) Thank you. [link] [comments]  |
| How are colors determined when coloring pictures taken with an Electron Microscope? Posted: 12 Nov 2016 08:50 PM PST I understand that colors are added in to Electron Microscope images but I am curious as to how the colors are chosen. Are they colored to imitate what the actual color is? Are they chosen randomly? Any information would be awesome! [link] [comments]  |
| Are propellers on nuclear subs/ships connected directly to the steam turbine of the reactor? Posted: 12 Nov 2016 02:43 PM PST Or is the steam turbine connected to a generator to make electricity to power electric motors for the propellers? [link] [comments]  |
| Posted: 12 Nov 2016 11:26 PM PST This is probably a stupid question. I saw this gif and then the question popped into my head. It really just applied to fish that can swim fast. With their speed and being able to make extreme turns and with their ability to go up and down, do they get dizzy? I know going in a circle makes humans dizzy, but what about sharks?

| When did modern ocean currents develop? Posted: 12 Nov 2016 11:20 AM PST I'm writing a paper right now about El Niño and North Atlantic Oscillation in the stratigraphic record and it got me wondering how far back we could actually hope to see these events. Did Atlantic currents start as soon as the ocean opened? If not, what caused the delay, and how do we know? [link] [comments]  |
| Where does the energy go in a solar cell when it is disconnected? Posted: 12 Nov 2016 06:48 PM PST In a diesel generator, if you increase the load, you have to supply more fuel to keep the engine-generator turning at the same speed. Accordingly, if you electrically disconnect the generator, the engine has to burn less fuel or it will overspeed. With a solar array, if E amount of energy is hitting the panel, some is turned to electricity, some is reflected, some is turned to heat, some passes through it, etc.... Presumably E-X(generatedkw) is going somewhere like reflected light and heating. If the array is generating 5kw of power and it is suddenly disconnected from the grid, what happens to that 5kw of energy? A shade doesn't extend and the sun doesn't dim, so E is still striking the surface. I would think that 5kw has to "go" somewhere, probably in the form of heat, but I've never heard of a panel getting brighter/hotter/whatever if it's "unplugged" compared to plugged in. Or maybe it does? 5kw of energy (~1.5 tons) would probably be a noticeable heat or light increase, I would think. ELI15: Where does the energy go, or what happens? [link] [comments]  |
| Is entropy uniformly distributed? Posted: 12 Nov 2016 06:19 PM PST Either in a local system or in the universe as a whole. Do we have any indication if you could have pockets if disorder and unpredictability? [link] [comments]  |
| We worry about astroids hitting the earth, but could the moon ever come so close as to collide ? Posted: 12 Nov 2016 09:48 PM PST Saw that the moon is passing by Monday at its closest in over 60 years. Wanted to know if this would ever be a risk factor. [link] [comments]  |
| Why is it that the inverse function of non-commutative operations is so difficult? Posted: 12 Nov 2016 11:44 AM PST The inverse of adding and multiplying is subtracting and dividing. Both addition and multiplication are commutative, and subtracting or dividing two numbers seems to require a very simple algorithm. Yet, for all operations as or more complex than exponentiation, it seems to take a lot of computing power, and no algorithm is simple enough to teach in grade school. What is the underlying mathematical reason behind this [link] [comments]  |
| Is there a reason we prefer instruments to start flat when tuning by ear? Posted: 12 Nov 2016 01:43 PM PST When I've talked to musicians about tuning by ear, they often say that it is easier to hear the pitch differences and tune accordingly if it is going from flat -> in-tune, as opposed to sharp -> in-tune. For instance, when tuning a guitar, often musicians will make the string they want to tune wildly flat and then bring it up to tune as opposed to making it sharp. Is there a known reason our ears would favor this transition more than a sharp-> in-tune transition? [link] [comments]  |
| Are there any simulations of the ocean levels in case of global cooling available? Posted: 12 Nov 2016 04:42 PM PST I have managed to find plenty of ones for global warming, but I'm curious about how the world would look if significant global cooling would occur, such as might be caused by a super volcano eruption.

| Posted: 12 Nov 2016 10:32 AM PST What cause the orbital dynamics of binary star systems and binary black hole systems that spiral in until they coalesce? If the binary stars or black holes are perfectly identical do they cancel out the gravitational waves that each emits during their rotations? Can two stars or black holes just coalesce without spiraling? [link] [comments]  |
