| When a sound-wave travels in an open pipe, what reflects it back in order to form a standing wave? Posted: 02 Oct 2018 04:47 AM PDT I understand that in a closed pipe, the closed end reflects the sound-wave back and forms a standing wave, but there's no physical thing to reflect off in an open pipe. So how does it reflect? [link] [comments]  |
| [Paleontology] Is there evidence of any dinosaurs having a cloaca? Posted: 01 Oct 2018 07:38 PM PDT Since birds are relatives of dinos, I would think some dinos, like a pteradactyl, would've had a cloaca. Is there any known evidence of this? [link] [comments]  |

| How do you calculate the average sum of dice rolls when a "drop the lowest roll" mechanic is used? Posted: 01 Oct 2018 03:38 PM PDT In various tabletop role-playing games, game designers will often use a system to set character statistics that is some derivation of "roll an x-sided die y-times, drop the lowest z rolls, and sum up the results." The most common example of this is rolling a 6-sided dice 4 times and dropping the lowest result. Now, calculating the average sum of 3 six-sided dice rolls is simple and intuitive, yielding a result of 10.5, but when adding a 4th and dropping the lowest result, the average comes out to a (seemingly) strange irrational number of ~12.22. There are other derivations of this problem that yield other seemingly random irrational values, and while I can get to the result by writing out all the combinations and summing up the probabilities, is there a way to write this problem out algebraically?

| What happens to earth once the sun "dies"? Posted: 01 Oct 2018 03:35 PM PDT One would think that the sun cannot go on forever, so what would happen to planet earth once its gone? Our orbit, our light, our everything... Would the sun explode and take Earth with it? [link] [comments]  |
| Posted: 01 Oct 2018 09:12 AM PDT I work with high pressure gas infrastructure (>1000 bar) where we use very strong and very expensive pressure vessels to store the gas at high pressure. A colleague came up with a 'novel' solution to this gas storage problem which in my gut I feel isn't plausible but i'm struggling to make the argument against it. I'm hoping you guys can either help me debunk it, or even prove me wrong. His suggestion is as follows: Lets say you have a pressure vessel containing gas at 300 bar. You put this 300 bar pressure vessel inside a second pressure vessel which contains gas at 200 bar. And you then put THAT pressure vessel inside a third vessel containing gas at 100 bar. You now have a russian doll pressure vessel system. His theory is that each pressure vessel will need only be designed to withstand 100 bar of pressure since the delta between each layer is 100 bar. Supposedly this theory would extend to 1000 bar and beyond. Purely based on theory and ignoring the practicalities of transferring gas in/out of the tanks - is this true/not true and if so, why?

| Posted: 01 Oct 2018 09:53 AM PDT Everybody knows falling into water from great heights can kill you, but what is it a combination of? Does speed and trajectory affect the impact? Can something hit water so hard it instantly stops? Do minerals and certain water deposits affect it also? [link] [comments]  |
| Posted: 01 Oct 2018 01:38 PM PDT I just came across a photo on the front page of the surface of a comet. What stood out to me was how there doesn't appear to be any stars visible in the background of the photo. On Earth, a clear night sky with no pollution would show a ton of stars. How come we see no stars in the "sky" of this comet or in the photos we have of the surface of the moon? [link] [comments]  |
| Do people with Broca's aphasia know that they have a limited vocabulary? Posted: 01 Oct 2018 09:08 PM PDT I know that in psychology, my teacher told me that people with Broca's aphasia can understand other people, but are they aware that they can't respond correctly? [link] [comments]  |
| What causes being right/left handed? Posted: 01 Oct 2018 09:01 AM PDT Popular joke says it's amazing how many wonderful things we can do with right hand when left one just sits there and doesn't know how to hold a pencil. There are many things that we can do with left hand but not with right one though. For example if one tried to drive a nail with switched hands, not only left hand will swing uncontrollable but holding the nail with right hand feels odd too. I just tried to play guitar with switched hands and both hands had no idea what to do. Actually left hand started adapting slowly when right one couldn't hold a single string correctly. So what actually makes us "right-handed"? Does it have generic background, neurologic? Or maybe it's the way how we learn things like most children just copy what others do, but some children mirror it and therefore they're left-handed. Would child with conditions to be right-handed become left-handed when surrounded by left-handed people and child with conditions to be left-handed become right-handed in such environment?

| Posted: 02 Oct 2018 12:07 AM PDT Since heavy elements are made in stars, where did the gases come from that formed the planets of the solar system? If our star is 5 billion years old and the universe is 14 billion, how did our solar system get the various amount of elements that is has? Did another star exist exactly where ours is today that died out and left the remnants of the heavier elements? If so, how many times do you think the solar system has "reset", I guess.

| Can mosquitos/bedbugs/fleas/other blood sucking bugs catch diseases from humans? Posted: 01 Oct 2018 08:03 AM PDT Lying in bed with the flu, being bit by mosquitos because summer and humidity yay! So it made me think whether or not we can pass diseases down to bugs that bite us same as we can transmit diseases and viruses to other humans via saliva/breath/close proximity. [link] [comments]  |

| Posted: 01 Oct 2018 07:18 AM PDT Would one come out of the anesthesia to a sleeping state again? Would one be less confused? I've read elsewhere that less anesthetic is required, is this just for the initial anesthesia, or would the dosage through a surgery remain lower? Is it safer, more dangerous, equally risky to be anesthetized while already asleep? [link] [comments]  |
