There's no sound in a vacuum because sounds are vibrations in the air, and in a vacuum there is no air to vibrate. So where does the energy that would go into vibrating the air particles go instead?

Where does heat go in space? Posted: 08 Feb 2018 06:14 AM PST Imagine you had a bottle of water (somehow not exploding in a vacuum), would it cool down after a while? and if so, how does it lose its heat? submitted by /u/Sam1122334 [link] [comments]

Why does vomiting relieve nausea even when the nausea is not caused by something in your digestive tract? Posted: 07 Feb 2018 10:32 PM PST For example, nausea caused by drug use via insufflation or unsettling images. submitted by /u/BrotherDBAD [link] [comments]

How exactly does injecting poultry with powerful antibiotics like Colistin affect the general population's resistance to infections? Posted: 08 Feb 2018 12:03 AM PST I'd read an alarming article wherein Colistin is heavily injected into Indian chickens and the implications of such practices. I was wondering how is the resistance to these medicines formed actually? Will those affected by this include people who don't eat these chickens as well?

How much of the energy that goes into a PC is transformed into heat? How does it compare to a space heater? Posted: 08 Feb 2018 01:37 AM PST I've just asked myself this since my old PC tower does warm up my room when it's on and after all, both a space heater and a computer produce heat by sending electricity through wiring, right? The computer's is just more intricate ... I was also wondering if this would make a computer doing calculations (CERN, folding proteins, cryptocurrency, ...) an efficient replacement for a space heater on either an individual or humanity-wide level. submitted by /u/Casual_Wizard [link] [comments]

Is it possible for an egg cell to experience nondisjunction of every chromosome, and if so, would it lead to a virgin birth? Posted: 08 Feb 2018 03:01 AM PST I was curious about this because of the recent NYTimes article about a species of mutant crawfish which is only female because it can clone itself through total nondisjunction in its eggs, creating clones of itself endlessly. Can such a thing happen in any species, and especially in humans? If it's possible, even if unlikely, would it lead to a virgin birth, as with the crawfish population? submitted by /u/CodeReaper [link] [comments]

I know the basics of how grid fins work, but why are grid fins built with diagonal lattices instead of square lattices? What is the optimum depth for grid fins? Posted: 07 Feb 2018 06:48 PM PST Grid fins, the big flat grids on the sides of some missiles and rockets, are used to redirect the path of air by forcing air through square "tubes" in the grid fin. I have some inquiries about the specifics of the shape of the grid fins. How deep should a grid fin be? If a grid fin is too shallow, there's less air correction, I assume. But what would make a grid fin too deep? Or is there no such thing as too deep when talking about grid fins? Why do grid fins use diagonal lattice grids opposed to square lattice grids? What exactly makes it more efficient? Thanks for reading my post, I would attach a link or image but I can't in this subreddit, but I'm pretty sure my post works with all grid fins. EDIT: I would put both engineering and physics as the flairs, but it seems like I can't do that. submitted by /u/purpleprick [link] [comments]

Low-level clouds aee huge masses of condensed water vapor. High-level clouds are ice particles. When/at what temperature does this change occur? Posted: 08 Feb 2018 12:58 AM PST As a follow-up, is the sun's heat above the clouds make it warm enough to melt back into water vapor and condense, or does it just stay like that until it melts in atmospheric heat? submitted by /u/GusBaur124 [link] [comments]

So the solar system is revolving around SgrA* ...are we getting any closer to it or we are just revolving on a fixed orbit? Posted: 08 Feb 2018 06:41 AM PST Also I don't get how do you prove that black holes are real using maths .. submitted by /u/EssamWisam [link] [comments]

Does smooth muscle activity help maintain body temperature? Posted: 07 Feb 2018 07:36 PM PST Does smooth muscle activity help maintain body temperature? If so how much compared to skeletal muscle or other ways of producing heat in the body? There was an unresolved discussion in class and I'm curious how much smooth muscle helps. submitted by /u/ender1824 [link] [comments]
