| Do cosmic rays ever pass through the LHC and if so, what happens to them in the accelerator? Posted: 20 Jan 2017 05:06 AM PST Do they continue straight and pass through it, or do they get accelerated around the tunnel? Are there any pictures of it happening from the detectors?

| At which spot/angle of a urinal should I aim towards to reduce the amount of splash-back? Posted: 19 Jan 2017 11:08 PM PST When urinating, is there a best angle to aim for that will reduce the amount of splash back men sometimes encounter? If so, how is it determined? [link] [comments]  |
| How do Antibiotics courses affect Gut Biota? Posted: 20 Jan 2017 05:48 AM PST Do they completely wipe them out, meaning you develop a new set after a course of antibiotics? Or is it only a partial effect? Does it depend on the antibiotic? [link] [comments]  |

| are we aware of any major evolutionary groups that went extinct? Posted: 19 Jan 2017 07:02 PM PST so i was just thinking about how monotremes have an extremely low number of species, they could have very easily gone extinct before modern history. in which case we would possibly have had no idea they ever even existed. so my question is, are we aware of any similar groups that did go extinct? and how different were those animals from their closest related group?

| What happens to the energy stored in an inductor if it is suddenly removed from a circuit? Posted: 19 Jan 2017 10:13 PM PST Assumptions are that the inductor is ideal and the circuit is placed in a vacuum. Also, the time taken to remove the inductor from the circuit is negligibly small.

| Posted: 19 Jan 2017 07:36 AM PST If we allow factors from C instead of just R, 5 = (2 + i) * (2 - i). A little googling led me to a funky idea called "gaussian primes", or numbers which are prime on the complex plane. Many of the real number primes seem to lose their primeness once complex factors are involved. My intuition is that if you add another plane, j, many more of the primes on C and R will become factorable. Even more once you add k,l,m,n, and so on. Are there any "super primes", which won't factor no matter how many dimensions you add? If so, do they follow any patterns? Or, is the only way to tell them apart a brute force search? If not, how many dimensions do you need to make all of R factorable? what about all of C? [link] [comments]  |

| Posted: 19 Jan 2017 09:24 AM PST We solve the Schrodinger equation for hydrogen, and out come some sets of eigenfunctions (r, theta, phi) with corresponding quantum numbers (n, l, m) that make up "orbitals," along with an energy something like -(13.6 eV)/n2. That energy obviously doesn't work on elements that aren't hydrogen, so why do the eigenfunctions? We talk about e.g. carbon having a 1s2 2s2 2p2 configuration. But those are hydrogen orbitals we're describing it with. No one's solved the Schrodinger equation and found carbon's eigenfunction solutions. So why can we use them with decent accuracy?

| Dentists; how does a precision apex locator (PAL) work? Posted: 19 Jan 2017 03:58 PM PST I had a root canal today and this was used. It looks like it may need to complete an electrical circuit for it to operate. When I asked my dentist about the mechanics behind it he said, "I don't know how it works, I just know it works".

| What liquid is the fastest flowing (least viscous) and the slowest flowing (most viscous)? Posted: 19 Jan 2017 10:31 AM PST I saw a post on r/funny and I became genuinely curious [link] [comments]  |
| Posted: 19 Jan 2017 12:35 PM PST Clearly bigger planets have more number of moons, but pluto, which had 5 moons, was much smaller than earth and earth only has one moon. So, what is it that makes a planet have more moons than other! [link] [comments]  |
| Is there an upper bound on the size of a star? Posted: 19 Jan 2017 12:29 PM PST As the title, is there an upper bound on the size of a star? Could there theoretically be a star the size of the entire solar system or larger? [link] [comments]  |
| Are there any cool elements we "just missed" having? Posted: 19 Jan 2017 09:35 PM PST Lots of elements have neat properties - helium has no freezing point, gallium melts in your hand, plutonium can take itself apart through a nuclear chain reaction, carbon forms a huge variety of bonds, silicon semiconductors gave us all Reddit, and so on. However, what if the physical constants had been very slightly different? Could there be even more awesome elements, that don't exist in our universe, but "could have" if $deity had rolled the dice a bit differently? [link] [comments]  |
| Can a smooth continuous function be exactly same as another in a range but different outside? Posted: 19 Jan 2017 07:10 AM PST I am not sure about the terminology, take two continuous differentiable funtions, what I mean is there are no kinks in them. Is it possible for them to be exactly the same in a finite range, but different outside? By exactly same I mean take any point in the range and the functions return exactly the same value no matter to which decimal point you calculate. So not like taylor series converging to a function.
