| Does the mass of a black hole increase by any appreciable amount by absorbing photons? Posted: 14 Apr 2016 01:24 PM PDT We all know that light cannot escape from black holes. Over the course of tens/hundreds/thousands of millions of years, does a black hole absorb so much light that its mass could measurably increase? [link] [comments]  |
| Posted: 14 Apr 2016 05:24 AM PDT It can be done with any number, so long as you don't find the sin of a sin, or the cos of a cos, or the tan of a tan What I mean is, you can do sin(cos(tan(sin(cos(tan(x))))))) for any combination of sin, cos, tan and get 0.0174 so long as there are no sin/cos/tan adjacent to each other. Why does this happen? [link] [comments]  |
| How does a tempered glass screen for your smart phone pass the sense of touch to the sensors below? Posted: 15 Apr 2016 06:44 AM PDT The title pretty much sums it up. I can guess that it would be through heat or possibly shadow but I can't say for sure. It probably isn't from pressure because the tempered glass seems very hard and therefore wouldn't flex much.

| Could you put a wind turbine on a sky-scraper? Posted: 14 Apr 2016 03:59 PM PDT I'm wondering if it's economically and technologically feasible to put a wind-farm style turbine on the roof of a sky-scraper or other tall building to generate power for that particular building. [link] [comments]  |
| How do rocket engines prevent back-flow of ignited fuel? Posted: 15 Apr 2016 12:26 AM PDT In other words, how is ignited fuel stopped from flowing up the fuel lines? And also if it did, what would happen? (Regard bi propellant rockets.) [link] [comments]  |
| Posted: 14 Apr 2016 03:54 PM PDT 4D objects theoretically can be seen in the third dimension which we live in, but we would only see a slice of the object. To us it would be 3D and natural. Are there certain geological shapes that regularly occur in this universe that point to a higher dimensional universe that we just can't see? If they point to a higher dimensional universe, do we simply dismiss this as having natural shape in a 3D universe. Could we be missing something right beneath our noses? [link] [comments]  |
| What would be the smallest thing from which to observe the effects of time dilation? Posted: 15 Apr 2016 06:07 AM PDT I understand that atoms for instance with their half life could show wether they've "jumped ahead" in time... Or do they? I have this impression mainly because of the vague understanding I have on how atomic clocks work. But could you go smaller? Could a single subatomical particle show time dilation's effects?

| Can information be transmitted through the weak or strong nuclear forces? Posted: 14 Apr 2016 01:53 PM PDT Seeing as we can measure the frequency of electromagnetic and gravitational waves and thereby transmit information using those forces, is it possible to do something similar with the weak or strong nuclear forces? Or do they only operate on a scale that prohibits useful applications? [link] [comments]  |
| Did the earth's geological axis ever change? Could there be a 'wobble' and the poles shift? Posted: 14 Apr 2016 03:39 PM PDT For example, could the south pole been further north, like in Australia? (not a question about magnetic poles) [link] [comments]  |
| What are some of Newton's less famous discoveries? Posted: 14 Apr 2016 10:22 AM PDT |
| Why is osmotic pressure divided by ZERO at the y-intercept in osmometry of polymers? Posted: 14 Apr 2016 12:13 PM PDT For determining the number average molecular weight of polymers by osmometry the following equation is used: (Pi/C) = RTA1 + CRTA2. C is concentration of solute, A1 is first virial constant, A2 is second virial constant, R is universal gas constant and T is temperature. The equation represents a straight line, where (Pi/C) is on Y-axis and C is on x-axis. Doesn't that mean that the y-intercept is equal (Pi/0) at C=0, So how is it possible ? [link] [comments]  |
| What are sugar's effects on our body? Posted: 14 Apr 2016 12:35 PM PDT I suppose this could be the wrong subreddit, but when I ask this question on google, all I get are clickbait lists and not-so-believable websites' takes on what could be the effects. I'm just trying to figure out if I'm correct when I say that "Coke Zero is better at waking you up and keeping you awake than regular Coke because the sugar will eventually make you tired."

| How do cation channels get specificity? Posted: 14 Apr 2016 04:25 PM PDT I understand that cations like Na+ will not go through Cl- channels because of cationic amino acid residues lining the Cl- channel pore, but how do cation channels select for 1 cation? Does Na+ flow through K+ channels? If not, what stops Na+ flow? [link] [comments]  |
| Why can some mosquito species carry viruses like zika and other species are unable to carry it? Posted: 14 Apr 2016 01:35 PM PDT |
| Why are the blades on hole punches a concave shape? Posted: 14 Apr 2016 11:39 AM PDT |
| Posted: 14 Apr 2016 02:23 PM PDT Hi, I am currently writing an essay on early years language development (0-8 years), more specifically on gender differences. Is there a clear scientific consensus on the differences? Who are the researchers, what major theories are there, is it all genetic or rather sociocultural? Thanks in advance! [link] [comments]  |

| Why do certain faces scare us? Like a smiling face, a blurry face, or... No face? Posted: 14 Apr 2016 12:28 PM PDT These seem to be popular in horror movies/stories but I'm not sure why they are so terrifying [link] [comments]  |
