Why doesn't the brain filter out Tinnitus? Posted: 15 Apr 2017 01:20 PM PDT I know that the brain filters out inputs after being present for too long (thus if you don't move your eyes AT ALL the room starts to fade to black). So why doesn't the brain filter out Tinnitus? It's there all the time. submitted by /u/Baelfire_Nightshade [link] [comments]

Does the aperture ratio matter when burning something with focused sunlight? Posted: 16 Apr 2017 06:32 AM PDT I was doing a little experiment with camera lenses. With 300mm f/4, the black tape started smoking almost immediately, but it seemed to me that 135mm f/2 lens was even faster with the smoke, despite the slightly smaller aperture opening. Is it the size of the aperture or the fastness of the lens that dictates how quickly focused sunlight does damage to surface? submitted by /u/jannne [link] [comments]

How do the supposed "color blind glasses" return color vision to an individual? Posted: 15 Apr 2017 04:08 PM PDT Do they do so at all? Is it a scam? Or do they just emulate a color that cannot be seen in terms of another color? I would imagine that if the cones for a color are not present, simply having glasses wouldn't accomplish anything. submitted by /u/Xalteox [link] [comments]

Whats the change in entropy when a kettle heats water, and the water is allowed to cool down? Posted: 16 Apr 2017 05:54 AM PDT When a 1kW kettle heats water at 20 degrees Celsius (293K) for 10s the entropy of the water increases by 34JK-1 And on cooling for 10 mins, 10kJ of the heat is transferred to the surroundings increasing its entropy by 34JK-1 What is the total entropy change? submitted by /u/Batatta [link] [comments]

If waves can be disrupted through destructive interference, and light travels in waves... Why can't we disrupt light? Posted: 16 Apr 2017 12:39 AM PDT I used to work with communications equipment in my last job. One of the things you could do to radio waves was broadcast at the inverse frequency to disrupt the signal. You can do similar things with sound, Wi-Fi etc. But why can't we do this with light? Is it possible? submitted by /u/JC537 [link] [comments]

Given a known velocity and location how can one predict the equation of an objects orbit? Posted: 15 Apr 2017 08:42 PM PDT I am wondering how to predict the shape and equation for an orbit assuming you know: the mass of the planet the mass of the object orbiting (probably small and irreverent) Velocity of object Location of object relative to the planet I am pretty sure that it is possible but I could not find an equation online that I could understand.

Could the expansion of the universe "contain" the possible vacuum decay bubble? Posted: 16 Apr 2017 03:52 AM PDT Kurzgesagt's video on vacuum decay: https://www.youtube.com/watch?v=ijFm6DxNVyI&t=294s Unless I'm completely mistaken, isn't the expansion of the universe happening at speeds over the speed of light depending on the distance between the two objects? Could this mean that if the vacuum decay bubble happened at a distance far enough from us that the expansion of the universe could prevent the vacuum decay bubble from ever reaching us? submitted by /u/Tomstefer [link] [comments]

Can any organisms see non-electromagnetic radiation? Posted: 15 Apr 2017 09:19 AM PDT Some examples would be cosmic rays, neutron radiation, alpha radiation, beta radiation, muon radiation, and antimatter radiation.

Does reading fiction increase empathy, or are empathic people more likely to read fiction? Posted: 15 Apr 2017 03:03 AM PDT Most research I've stumbled across said something about reading fiction improving empathy, but some people say it's the other way around. Which one causes the other? Or are they both false? submitted by /u/Aravoid0 [link] [comments]

What exactly changes in your brain to make you start feeling very sleepy? Less energy, different mix of neurochemicals, slower metabolism, etc? Posted: 15 Apr 2017 06:15 AM PDT Wikipedia offers this sentence: Process S is driven by the depletion of glycogen and accumulation of adenosine in the forebrain that disinhibits the Ventrolateral preoptic nucleus, allowing for inhibition of the ascending reticular activating system. ...which seems at least on-target. But there must be still more going on and better ways of explaining it. submitted by /u/OdysseusPrime [link] [comments]

Posted: 14 Apr 2017 02:05 PM PDT I know breasts get larger during pregnancy, so is that when the milk production really begins? Are breasts otherwise dormant? If they're for energy reserves, do large breasts protect the individual from famine, or is that fat reserved for potential offspring? submitted by /u/mtattyt [link] [comments]

How does water become super clear in the wild? What happens to suspended solids, algae, and plankton? Posted: 14 Apr 2017 04:44 PM PDT There's a photo that showed up on the front page that showed crystal clear water in a stream (http://imgur.com/kmfy5Um ); some of you may have seen images of the water off the coast of the Maldives, which is so clear row boats in the water look like they're floating in air. How does water get this clear without filtration and sterilization in the wild? Why doesn't algae and other life and biological residues fill it up and make it cloudy? In the case of the Maldives, aren't there plankton in the water? In the case of the stream in Sweden linked above, you can see dead grass in the water; if it flowed there across any sort of land and if the stream or pond has dead plant matter in it, why hasn't it carried suspended biological residues into the water? (And lastly, is it possible to simulate those processes for man-made ponds?) submitted by /u/Berkamin [link] [comments]

How are quantum tunneling in stars and their weight associated with each other? Posted: 14 Apr 2017 04:45 PM PDT Hey askscience! So today a friend asked me about the nuclear fusion inside the sun, and I gave the explanation that it occurs in the sun's core due to the sheer pressure within itself that allows the helium atoms to overcome the coulomb force and fuse together into helium. I know that that is at least inaccurate, but since I can't explain quantum tunneling appropriately and I have heard so many versions of the explanation I chose to give all over, I thought it would be best to mistrust my gut feeling and gave the answer mentioned above. So is my answer widely false or just inaccurate? Is there just a correlation between the sun's mass and quantum tunneling (i.e. lots of protons necessary for quantum tunneling having the effect you can observe every day = lots of protons to make up all that mass) or is there a bit of causation as well (i.e. the mass is helping quantum tunneling to Some extent)? Edit: also yeah, should be 'mass' instead of 'weight' in the title submitted by /u/Remarqueable [link] [comments]

Delayed Sleep Phase Disorder and Melatonin. What are the cellular interactions and/or mutations that cause the disorder? Posted: 14 Apr 2017 11:58 AM PDT Circadian rhythm sleep disorders (CRSD) fall under an umbrella of disorders that are caused by alterations to the circadian rhythms within the body. Delayed sleep phase disorder (DSPD) is a several hour delay in the sleep/wake cycle associated with CRSD. This is the most common occurring CRSD and can result from a multitude of psychological and social disorders. I am struggling to find information on mutations within the structures/processes of the pathway that causes the disorder to present in patients suffering from DSPD. I understand the genetic component of the disorder and the relevance of CLOCK genes. Would anyone be able to elaborate on the cellular pathway involved with CRSD or DSPD specifically? submitted by /u/brokebiochemkid [link] [comments]

AskScience AMA Series: I am Scott Solomon, evolutionary biologist, science writer, and university professor, out with a new book on predicting the evolutionary future of humans. Ask Me Anything! Posted: 14 Apr 2017 05:00 AM PDT I'm Scott Solomon, an evolutionary biologist, science writer, and university professor. My new book, Future Humans: Inside the Science of Our Continuing Evolution, considers how we can use science to make informed predictions about our evolutionary future. Recent research suggests that humans are indeed still evolving, but modernization is affecting the way that natural selection and other mechanisms of evolution affect us today. Technology, medicine, demographic changes, and globalization all seem to be having an impact on our ongoing evolution. But our long-term fate as a species may depend on how we choose to utilize emerging technologies, like CRISPR gene editing or the ability to establish permanent colonies on other planets. Here is a video in which I discuss how colonizing Mars could affect our evolution: https://youtu.be/uHo1sL-P4n4 This article also discusses some of my ideas on the ways humans might evolve on Mars: http://www.nbcnews.com/mach/space/mars-colonists-might-evolve-entirely-new-type-human-n708636 In this video I discuss how online dating may be affecting human mate choice: https://youtu.be/9oOGFjJn4OA I'll be on between 3-5pm eastern (19-21 UT).

What's the estimated pressure on Enceladus' sub-surface ocean? Posted: 13 Apr 2017 04:00 PM PDT Recently NASA made a press release discussing the possibility of life in Enceladus' sub-surface ocean. Enceladus is much smaller than Earth and therefore has far weaker gravity, which would correlate with smaller pressure at a given altitude. However, its ocean seems to occupy a larger percentage of the planet's volume compared to Earth's, in addition to being buried under a thick sheet of ice. Given Enceladus' size, gravity, and nature of it's sub-surface ocean, what would its water pressure ranges be? Could a human swim in it without a pressure suit? Could a submarine reach any depth? Bonus question is to estimate the temperature range of the ocean. Since it's liquid, it'd have to be above zero celsius unless it's highly saline. Is there expected geothermal or tidal friction heating? How warm would it be purely from solar exposure, or radiation coming from Saturn? submitted by /u/GeneReddit123 [link] [comments]

What differentiates two similar elementary particles? Posted: 14 Apr 2017 03:27 AM PDT If elementary particles are the fundamental building blocks of everything, this means that they themselves are not made up of anything but themselves.

Where exactly at black holes does hawking radiation occur? Posted: 14 Apr 2017 02:42 AM PDT Apparently some say it occurs at the event horizon, others say much further away. I would've thought it's close to the "surface" of the mass. So let me start here. I assume that a black hole is a spherical piece of mass such as a neutron star, just denser, and massive enough to "capture" light as well as creating a no light zone around it. The more massive a black hole, the bigger this zone is. The more massive a black hole (bh), the less hawking radiation (hr). Now my problem: If hr occurs at the event horizon, the virtual particle escaping it would need to travel close to the speed of light but would be a lot of energy for a random occurence with very little energy (?). If it occurs millions of km away and the escaping particle just barely hits just the distance from the bh where it's velocity would allow it to not instantly get dragged back, wouldnt it just go into orbit around the bh and then not be hr? (I realize we don't really know too much about virtual particle's interaction with gravity, or do we?) Now the only logical way for hr to work for me is this; hr only occurs directly on the surface of the piece of mass. (not the event horizon) Virtual particles are not affected by gravity in any way. The virtual particle annihilating in the bh just happend to travel right into the surface when it was created while the other one just happend not to, because it went the other way and continues to do so beacause it's counter part found another counter part in the bh. In my theory black hole's surfaces are smaller, the more massive they are, because they attrack it's own mass more and don't care about density limitations. Meaning the less massive a bh, the more surface, the more likely one of these hr processes becomes, thus increasing hr effectively. This would explain exactly why more massive black holes have less hr and not more. Sorry if it's dumb or obvious and I am not a native speaker, so sorry for ineffective or unclear language. Thanks for reading. submitted by /u/luigitrash [link] [comments]

How does one calculate inductive voltage spikes? Posted: 14 Apr 2017 02:32 AM PDT So yes I understand that the voltage is related by di/dt and we have discussed how to mitigate it away from sensitive components, but how do you calculate how large the voltage will be or more specifically an estimation of Δt for "sudden" changes in current. I assume for transistors rise and fall times would be a good estimation. What about for mechanical relays and switches? And semi-related do audio speakers create inductive spikes even though they are rated in ohms? I assume the resistive characteristics outweigh the inductive but could it cause damage to a transistor? submitted by /u/Iwannabesmurt [link] [comments]

When physicists talk about energy scales, what does that mean? Posted: 13 Apr 2017 07:37 AM PDT You often hear about what theory predicts will happen at the GUT scale or the Planck scale or a scale of 1016 GeV. What do those mean? Is it saying that, we expect that if a system of particles collides with a kinetic energy of X we expect Y? How microscopic does a system have to be before you can consider it "at that scale?" Macroscopically speaking 1016 GeV is pretty small, like the energy of a car crash or the electricity to run the average American house for less than an hour, but clearly we aren't seeing Grand Unification in happen in a car crash. submitted by /u/bigscience87 [link] [comments]

How do attractive forces actually work? Posted: 13 Apr 2017 08:54 PM PDT For example gravity, magnetism and electrostatic. Do particles pull towards each other by some link like an elastic band or do they emit particles in the opposite direction to each other to push them together (if so how do they know to do that?) or is it something else entirely? submitted by /u/oA1i3No [link] [comments]

Do any species have social hierarchies independent of gender? Posted: 14 Apr 2017 05:35 AM PDT For example, it is the lion's role to 'protect' lionesses of the pride, and the Queen Ant is the one to lay eggs whilst the male drones scavenge for food, but do some (or many) animal species have social structures without differences in gender/sex? submitted by /u/LegitMeerkat [link] [comments]

Does the Radial Probability Wavefunction tell us anything on its own? Posted: 13 Apr 2017 07:23 PM PDT Hello everyone. In one of my recent lectures, we've been learning a bit about Schrodinger's Equation, in particular how it applies to the Hydrogen Atom. In deriving the wavefunction for this, we came up with the Radial Probability Wavefunction, but my professor also mentioned that, despite its naming, it did not give us the most probable radius for an electron to be in, but that was rather given by a different form that took into account volume. In relation to my above question, what does the Radial Probability Wavefunction tell us on its own? Is it a measure of radius, like its name implies, or something else? Or is it meaningless without taking into account volume? submitted by /u/Quick_Question404 [link] [comments]

Is there any relationship between antibonding orbitals and pi bonds? Posted: 13 Apr 2017 09:15 PM PDT Antibonding orbitals have higher energies and I was simply wondering if that is in any way connected to the concept of sigma/pi bonds since pi bonds are typically more unstable/filled last. Does each individual sigma and pi bond have its own bonding/antibonding orbital(s)? Also, if the conduction band simply corresponds to electrons in antibonding orbitals, are these electrons not still bound? Is the term conduction band not then a misnomer? submitted by /u/CallMeDoc24 [link] [comments]

Why is Single-Mode Fiber Optic named as such? Posted: 13 Apr 2017 09:20 PM PDT To my understanding in order for light to traverse a bend in the fiber optic it must reflect of the cladding, creating dispersion and multiple modes. What am I missing? submitted by /u/DigiPhlips [link] [comments]

If Jupiter was to just disappear suddenly and the asteroid belt would start accreting into a new planet, how long would it take for the accretion to finish? Posted: 13 Apr 2017 02:37 PM PDT submitted by /u/off-and-on [link] [comments]

Do objects constantly lose a tiny bit of mass due to emitting infrared radiation because of e=mc^2? Posted: 13 Apr 2017 08:25 PM PDT submitted by /u/c499 [link] [comments]

How often do 'typical' particles change state? E.g electrons flipping spin in the terahertz range, etc. Posted: 13 Apr 2017 11:48 PM PDT My thought is that measuring a particle usually just looks at a brief slice of it's lifetime, and it's usually lost and always altered randomly by the process. If one were track the 'realtime reality' of a vast number of particles, would one expect most of them to stay mostly constant until each interacted with something else, or would it be a 'glitter' of constantly changing spins and polarities? Does the polarity of a photon emitted from a distant star maintain a static polarity until measured, or does it change many times along the journey? submitted by /u/Ghosttwo [link] [comments]

eyesight, is it rgb, cmyk or spectrum? Posted: 13 Apr 2017 08:01 AM PDT I know that light is a spectrum, and our eyes see many variances. and that most of our vision is black and white and blurry, and that detail is like looking through a toilet roll middle. but do we see in rgb, cmyk or is it a whole spectrum that gets decoded in the brain? submitted by /u/Hate_Feight [link] [comments]
