| What actually is the dial up internet noise? Posted: 22 Mar 2019 06:05 PM PDT What actually is the dial up internet noise that's instantly recognisable? There's a couple of noises that sound like key presses but there are a number of others that have no comparatives. What is it? [link] [comments]  |
| How do animals react to an albino animal of the same species? Posted: 22 Mar 2019 12:47 PM PDT Do animals react in a strange way when they see an albino animal of their own species, or do they react the same as they would to an animal of their species that wasn't albino? [link] [comments]  |

| How big would LaGrange Point L4 (or L5) be... Are we talking 100s of metres or miles? Posted: 23 Mar 2019 02:51 AM PDT I've read that they are like a gravity bowl, catching dust and trojan asteroids. Just wondered how 'big' would this bowl be? Seems like an ideal place(s) to build a massive space station. [link] [comments]  |

| Why is the carbon-fluorine bond the strongest? Posted: 23 Mar 2019 02:10 AM PDT I would like to know why it has a high bond enthalpy, even though it is the most electronegative (which should mean it could polarize and leave the carbon easier). If electronegativity isn't the only factor, what else is? Thanks a lot. [link] [comments]  |
| How long does it take to grow a lab created sapphire? Posted: 23 Mar 2019 02:10 AM PDT What is the process like to grow gems in a lab? Is the process longer or shorter as compared to naturally growing them? [link] [comments]  |
| What is the mechanism behind gas knowing there's a vacuum behind a solid wall? Posted: 23 Mar 2019 01:03 AM PDT Take a vacuum insulated bottle for example. If its not made from strong enough materials it will implode. How does the air know to push against the wall? Does pulling the vacuum and the resulting air pushing down store potential energy and if it does, could we implement this effect in energy storage? [link] [comments]  |
| In string theory, spacetime is emergent. Are strings and branes fundamental? Posted: 22 Mar 2019 07:49 PM PDT In string theory, strings and branes are fundamental and not made of anything more fundamental (or so I thought) but string theorists like Susskind and Greene say spacetime is not fundamental but emergent from something else. Does this mean strings and branes are no longer considered fundamental but excited states of some underlying field? Thanks. [link] [comments]  |
| A reverse hydrolysis (if possible) would release energy? Posted: 23 Mar 2019 01:44 AM PDT When you do a hydrolysis, atoms take electrons so they don't need to be attached. If you could do a reverse hydrolysis, it would release energy? [link] [comments]  |
| Why doesn't an electron just fall down onto the nucleus? Posted: 22 Mar 2019 02:20 PM PDT I'm a sociologist by education but I've been feeling ashamed of not being as in the know about natural sciences lately so I'm basically re-educating myself through the entire school curriculum in my free time. This time I am having trouble understanding how atom works. I googled a lot of smart stuff but it was apparently too smart for me and now my brain is full of conflicting things. So, I learned that the planetary model of the atom that we're taught in school is a gross oversimplification and is wrong. Atoms are not small negatively charged spheres flying in circles around a bunch of positively charged spheres. They're more like a spherical cloud of positively charged probabilities surrounded by a shell-shaped cloud of negatively charged probabilities. But they still have charge, and are still attracted towards each other, no? Why would their shape change anything, won't the clouds still get squished towards each other? All I've read about it online has too many formulas for my feeble social sciences brain and more or less boils down to uncertainty principle. As in, the closer an electron is to the nucleus, the more defined its position becomes, therefore its momentum becomes less defined. In other words, the more we know about its location, the faster it becomes. But how getting faster would change anything? Won't that mean that you're just going down faster? Another thing I've found on the topic is that a sum of an electron and a proton is less in mass than a neutron. Is that's why? The nature just doesn't have any ways for an electron and a proton to interact other than turning into a neutron so unless extra energy is supplied from the outside, the electron just politely waits by the nucleus? And anyway, I remember reading that particles like to occupy the lowest possible energy state and somehow, for an electron it's in the middle between being too far from a nucleus and too close to a nucleus. But that sounds fishy to me, won't it actually be less energetic for negative and positive charges to just cancel out and be done away with the energy completely? The way I see it, there must be some force balancing out the electromagnetic one pulling the differently charged particles together. It can't be strong nuclear force since it doesn't affect electrons. Is it the degeneracy pressure thingamabob caused by Pauli exclusion principle? Since two fermions can't occupy the same place, when the fuzzy edges of probability clouds that are particles start touching they're repelled and that's what balances the electromagnetic attraction? Please help, I just don't understand why don't we all and all known Universe just doesn't collapse onto itself. [link] [comments]  |

| Why don't we digest tapeworms? Posted: 22 Mar 2019 05:43 AM PDT Our bodies are pretty good at digesting lots of things. How do people get a tapeworm without it being dissolved and used for food? [link] [comments]  |

| Are there any birds that engage in surplus killing? Posted: 22 Mar 2019 12:09 PM PDT Surplus killing, as in the behavior in which animals kill things they don't immediately intend to eat, is most common in mammals to my understanding. Are there any birds that do it? I would also appreciate knowing any birds known for just killing lots of things, even if not technically surface killing in some way. Thank you! [link] [comments]  |
| If we send a submersible probe to Europa, how will it communicate with us? Posted: 22 Mar 2019 07:22 AM PDT What kind of problem does the 10km+ thick ice sheet pose in sending information back to earth? What are some of the possible solutions to this problem? [link] [comments]  |
| How is sublimation (The change in a state of matter from solid to gas) possible? Posted: 22 Mar 2019 11:31 AM PDT From my understanding, the state of a type of matter depends on how the atoms around each other move. atoms in a solid do not move, atoms in a liquid slide around one another, and atoms in a gas move about freely. So how can an atom sublimate from a certain matter moving straight from solid to gas? Wouldn't it at some point have to become a liquid first? Even if for the tiniest fraction of a second?

| How are satellite images captured and edited? Posted: 22 Mar 2019 10:31 AM PDT How are satellite images captured and edited? What different censors are there and what is done to the raw data? Most of the images look like they're color corrected and originally false color, for example - is that correct? I'm especially interested in the question if there are any satellites equipped conventional modern high-res censors, as opposed to spectral imaging or other purely scientific methods, as I couldn't find any beyond what's been taken in LEO from the ISS. I understand this wouldn't make much sense from a research standpoint, but surely there must be some interest in seeing the earth as it would appear to a human observer. [link] [comments]  |
| Posted: 22 Mar 2019 04:25 PM PDT I've been watching some material on quantum physics and I've been trying to build a conceptual model of light in my head that fits both classical mechanics and quantum mechanics. From what I've gathered the amplitude would be the number of photons being given off and the frequency would be the amount of energy per photon? There really isn't any material that explains this concisely. Would this model be correct? [link] [comments]  |
