What color does the human eye track the best? Posted: 23 Dec 2016 12:15 AM PST So say you had a dot moving around, what color dot would the human eye be able to follow and react to the fastest and most accurately? submitted by /u/omeepo [link] [comments]

Could we detect an antimatter star? Posted: 22 Dec 2016 07:00 PM PST Using any ground or space telescopes, can we distinguish a star made of antimatter from a matter star should one exist? submitted by /u/FTLSquid [link] [comments]

What is Exactly one second? And can the duration of a second change? Posted: 22 Dec 2016 06:20 PM PST I have been thinking a lot but how do you define one second? And can the duration on one second be changed or it is already changing? Or is constant submitted by /u/Rakesh1995 [link] [comments]

[Chemistry] Helium has a higher 1st ionization energy than any other neutral atom. Is it possible to create a compound which is more difficult to remove an electron from? Posted: 22 Dec 2016 08:24 PM PST Helium's ionization energy is about 2370 kJ/mol which is higher than any other element's and is also higher than all bond energies (that I know of). However, is it possible to create some neutral compound which is harder to remove an electron from? I'm thinking teflon or some sort of fullerene would come closest but I'm not sure. submitted by /u/OfSomePersuasion [link] [comments]

Since beta particles are electrons, can they be directly converted to electrical energy? Posted: 22 Dec 2016 05:56 PM PST Please correct me if I'm wrong, but if you had a beta emitter and a piece of lead next to each other, the emitter would emit negatively-charged beta particles and become positively charged, while the lead would absorb the beta particles and become negatively charged. If this occurs, is it practical as a power source? submitted by /u/TheSteganographer [link] [comments]

Would burning off alcohol reduce the volume of a liquid? Posted: 22 Dec 2016 07:33 PM PST I'm a cook, and we flambe a lot of alcohol before using it so that things will still freeze and set properly and there is always a significant difference in how much liquid is in the pan when we add it and when the flame goes out, but it is also on the burner so I would assume evaporation is playing a large part in that. That being said, in a perfect situation where the alcohol was heated to combustion but not enough for it to evaporate and you let the flame burn as long as possible, would 100ml of a 40% alcohol liquid end up as 60ml? submitted by /u/SanicTehHedgehoge [link] [comments]

Are there any animal species that exist in BOTH polar regions? Posted: 22 Dec 2016 10:47 AM PST Animals like polar bears only live in the arctic while penguins are only in the antarctic. It makes sense that you wouldn't find either in both regions as it would require travel through the tropical center latitudes which is not condusive to their lifestyle. Are there any animals out there that buck this trend and can be found at both polar regions? submitted by /u/V1per41 [link] [comments]

How do you determine experimental certainty? Posted: 22 Dec 2016 03:06 PM PST I'm conducting an "experiment" for a game, and I was wondering, how do you determine how certain you are of your answer? Eg. if something happened 7 out of 100 times, are you certain to the tens or the ones place? submitted by /u/jamd315 [link] [comments]

Is there a difference in warming up my car on a cold day in Park or in Drive? Posted: 22 Dec 2016 06:37 AM PST The parking lot at my work is fairly large, and it takes a minute to navigate out of it. Is there a difference if I let my car idol in Park, or can I put in in Drive and creep forward (not touching the gas pedal at all) with no ill effect? submitted by /u/Willziac [link] [comments]

What is the rate of pressure change through a medium? Posted: 22 Dec 2016 12:26 PM PST (Sorry about the strange way of phrasing the question but a quick Google search on pressure change and the like leads down a bunch of wrong way streets.) When I'm in room with two doors and I open one of them, I can usually hear a bump from the door at the other end of the hallway because of (I believe) the decrease in pressure causing the door to shift. So if I were to open the door at the end of a 100 meter long hallway, how long before a door at the other end would shift in response? Hence, what is the speed of pressure change through air? submitted by /u/Laimbrane [link] [comments]

What are some downstream effects of this year's unprecedented Arctic heat wave? Posted: 22 Dec 2016 11:54 AM PST This article mentions a 50-degree variance from historic averages, which sounds insanely large to my uneducated mind...Wouldn't that absolutely devastate e.g. plants that require freezing to go dormant? Are there likely to be large population adjustments due specifically to one season of these extreme temperatures? submitted by /u/ProLicks [link] [comments]

If Gut Bacteria Between People Is Different, Could Transplantation Affect Caloric Requirements? Posted: 22 Dec 2016 05:55 AM PST So... someone please explain this to me. Everyone has different gut bacteria... some people's are more different than others to the point that transferring fecal matter from one persons gut to another's can cure some diseases per the following article. http://www.nydailynews.com/life-style/health/poop-pill-restore-digestive-balance-article-1.1475947 Logic would point that some gut bacteria is more capable of breaking down food in our gut than other strains, and therefore people with said gut bacteria would require less food to survive. By this logic, would it not make sense to lessen caloric requirements in the 3rd world by transplanting or bio-engineering gut bacteria in pill form to give people a greater ability to harness energy from food? Would the inverse not also work for helping obese people lose weight? I am curious if this line of thought has been explored before. Seems like this could solve a lot of problems... submitted by /u/milangdo [link] [comments]

Megathread: Anti-hydrogen/anti-matter Posted: 21 Dec 2016 08:46 AM PST Hi everyone, We're getting a lot of questions related to the recent discovery of the anti-hydrogen spectrum. There's already an AskScience thread but we thought we'd open up the floor and collect all additional questions here for further discussion. BBC News Nature, with the paper ScienceAlert submitted by /u/AskScienceModerator [link] [comments]

Why won't my touchscreen recognize leather gloves? Posted: 22 Dec 2016 06:05 AM PST Would someone explain this to me? Since leather is animal skin I thought leather gloves might work with my smartphone. submitted by /u/JankyChris [link] [comments]

Why does it seem like so many artificial elements are made by combining Calcium with some other element? Posted: 21 Dec 2016 08:19 PM PST I've looked at some synthetic element creation processes, and it seems like a large portion of them produce element X by combining Calcium with element number X-minus-20. Why is this? Why can't they combine Argon with element number X-minus-18? Why does Calcium seem to be the king? submitted by /u/WaitForItTheMongols [link] [comments]

How/Why did it snow in the Sahara Desert just very recently? Posted: 21 Dec 2016 11:36 AM PST I've seen the same pictures on a lot of different media that it has snowed on the Sahara Desert (http://www.telegraph.co.uk/news/2016/12/20/stunning-photos-capture-rare-snow-sahara-desert/) and that it hasn't snowed in about 40 years. So, how did this happen and why? submitted by /u/leandroqm [link] [comments]

Can Pluto become a planet? Posted: 22 Dec 2016 07:20 AM PST Hello everyone! Can Pluto gain enough mass by getting hit by meteorites and other small bodies to the point it becomes "clearing" its orbit and fulfilling all IAU's conditions? Or are we already past this point on the Solar System's history? submitted by /u/Mistdwellerr [link] [comments]

What is the largest an impact crater on earth can be? Posted: 21 Dec 2016 07:05 PM PST How big can an impact crater on earth be? This is an indirect way of asking how big can an object be before it completely destroys the earth upon impact, leaving no impact crater? submitted by /u/heisenberger [link] [comments]

Are single-biome worlds possible? Posted: 21 Dec 2016 09:16 PM PST Science fiction often presents worlds that have only one biome or are dominated by a particular biome (the forest moon of Endor and Hoth from Star Wars or Arrakis from Dune come to mind). Could we ever find real planets/moons like that? submitted by /u/BrainPunter [link] [comments]

Why can't nuclear power plants be scaled down more? Or, if they can, why arn't people doing it? Posted: 21 Dec 2016 03:17 PM PST Specifically, If i wanted to build an MSR in my backyard, to power my house or something, what would stop me from doing it? Is it just too cost prohibitive, or is there something about the nature of these devices that makes them only viable at large scales? Edit: Thank you all for your responses, I am currently playing around with Genetic programming, and was wondering if it was going to be a waste of my time to try and simulate a more efficient system. I'm starting to think it might be.... Oh well, Learn something new every day. submitted by /u/TheUltraMerchant [link] [comments]

Why does the Pauli exclusion principle cause the strong nuclear force to be repulsive at short distances? Posted: 22 Dec 2016 05:37 AM PST So the strong force acts in the positive direction (repulsive force) at short distances otherwise it would violate the exclusion principle. But why do short distances violate it? Which quantum property/number is violated with distance? submitted by /u/RavernousPenguin [link] [comments]

Why don't celestial bodies far away from stars eventually reach absolute zero just by radiating heat without a substantial influx of energy? Posted: 21 Dec 2016 11:44 PM PST I don't have a scientific background, but I love to science. I'm thinking of planetoids very far away from the stars, like Pluto or stuff within the Oort Cloud. Clearly, it's very cold on Pluto, something like -220C, but what I don't understand is why doesn't it keep getting colder? Is the sun's energy enough to keep it stable at -220C that far out or is there something else at play here? submitted by /u/ibak [link] [comments]

How do they measure a planet's size? Do they measure from where the atmosphere begins, or where the planet's mass begins? Posted: 21 Dec 2016 05:56 PM PST I was just thinking over how they measure the diameter of Jupiter. submitted by /u/Smutter0 [link] [comments]

How can something pickup nearby radio frequencies if it does not have a radio capability itself? Posted: 22 Dec 2016 01:30 AM PST My boyfriend and I were playing around with a small handheld analog synthesizer. It's only functions are similar to a keyboard with effect knobs. Upon turning it on there was some distorted convo that sounded like some kind of a radio broadcast somewhere. The synth doesn't have recording capabilities either, so it's not like it was a recorded playback. I've encountered this a few times before with different electronics with speakers, such as a toy car. I was wondering how this happens? submitted by /u/strangecacti [link] [comments]

How does wind effect sound? Posted: 21 Dec 2016 05:24 PM PST submitted by /u/420-69er [link] [comments]

Is there such a thing as endangered plants??? Posted: 21 Dec 2016 11:36 AM PST Do we have plants that are endangered, or records of plants that have gone extinct?? I am not knowledgeable on this subject. I know we find plants preserved in amber and stone, but the ones I recall seeing are things like wheat and ergot and flowers that we still have around today. I would also like to know if humans have ever purposefully eradicated a plant, or of that's possible. submitted by /u/Its_Farley [link] [comments]

Can galaxies have an overall electric charge or magnetic field? Posted: 21 Dec 2016 02:49 PM PST I'm assuming they wouldn't have a charge since most of the things making up a galaxy are neutral. But there are many celestial bodies with magnetic fields, so do they "add up" to create a galactic-scale field? What effect does rotation have? And would they be significant enough to affect the motions of other galaxies? submitted by /u/104084485 [link] [comments]

Why isn't the Y in xyY color space the same as the B in HSB color space? Posted: 21 Dec 2016 03:55 PM PST I'm having trouble understanding this. xyY is just a way people represent XYZ in 2D. For a given (x,y) (note: small x and y), different values of Y will change its brightness, but won't actually change where the point appears on an xy chromaticity plot. What that intuitively tells me is that its hue (the direction from the center gray point, for example) and its saturation (the distance from the gray point) should be independent of Y (again, for a constant (x,y)). So what I'd expect is that if were talking about xyY space and you took (0.2,0.1,0.1) (a really dark blue) and (0.2,0.1,0.9) (a nice bright blue), and converted them both to HSB space and looked at the values, they'd have the same H and S values, but a different B value. Yet, they don't, which you can see by messing around with this converter for example. I'd just look at the transformation it's doing, but the only actual equations I can find are here, and it would involve going xyY->XYZ->RGB->HSB... So why aren't Y (in xyY space) and B (in HSB) the same? submitted by /u/integrals4daze [link] [comments]

When you exercise and you burn calories, at what point do the calories actually leave your body? Is it during the exercise, or sometime after? Posted: 21 Dec 2016 02:40 PM PST I believe calories leave the body through your breath when you exhale, but I'm just curious at what point they actually leave the body. submitted by /u/murph94 [link] [comments]

What causes a Tsunami NOT to form? Posted: 21 Dec 2016 07:12 AM PST I get that a sharp rise in the ocean floor during an earthquake can cause a tsunami. but it seems relatively common that most ocean-borne earthquakes do not result in a tsunami. What's preventing them from forming? submitted by /u/williamrikersisland [link] [comments]

With today's discovery that hydrogen and anti-hydrogen have the same spectra, should we start considering the possibility that many recorded galaxies may be made of anti-matter? Posted: 20 Dec 2016 06:23 PM PST It just makes me wonder if it's possible, especially if the distance between such a cluster and one of matter could be so far apart we wouldn't see the light emitted from the cancellation as there may be no large scale interactions. edit: Thank you for all of the messages about my flair. An easy mistake on behalf of the mods. I messaged them in hope of them changing it. submitted by /u/DaKing97 [link] [comments]

Why does the point of maximum power for a solar cell exist? How do you calculate its position? Posted: 21 Dec 2016 06:15 AM PST What I am talking about is the point called "MPP" on the third graph on this page. The current just suddenly starts going to zero when the voltage hits a certain point, meaning that the resistance has also reached a certain value. How do you predict where that point will be located and why is it that way? Need it for school. Thank you. submitted by /u/santa_snickers [link] [comments]

What is the science behind extremism, such as "all-or-nothing" and "black-and-white" beliefs, and why is it hard for some to find a middle ground? Posted: 21 Dec 2016 05:22 AM PST Just as an example that pops into my head: take proponents of two opposing politics -- republicans and democrats. Or take capitalists/communists, or theists/atheists, etc. One can find extremists on both sides who accept their doctrine whole-sale and condemn any deviation from it. What is the science behind this and in particular, why is it difficult for some people to find a middle ground? submitted by /u/_4___ [link] [comments]

Is Deal or No Deal just a 30min long version of the Monty Hall Problem? Posted: 20 Dec 2016 02:21 PM PST While baking Christmas cookies I left GSN on as background noise. Eventually Deal or No Deal came on so I went to change the channel because I like GSN for the trivia not the random luck based games. As I was scrolling through the TV guide, I was thinking to myself that at the very end of Deal or No Deal when the contestant is given the option to switch the case they initially took for the last remaining case (when only two cases are left) that the entire game turns into an extended version of the Monty Hall problem. Is this true? If so what's the percent chance increase that the new case is the million dollar case if you decide to switch? (assuming that one random case and the million dollar case are left in play). submitted by /u/_I_Crazy_I_Chef_I_ [link] [comments]

Is a water soluble calcium salt less likely to be ionized in stomach acid than a poorly soluble calcium salt? Posted: 21 Dec 2016 12:51 AM PST Pretty intense. Long story short: HMB is sold as FA (free acid) and HMB-CA (calcium salt), the selling point on the FA is that it has better absorption (HMB), but I realized a while back that calcium ionized in the stomach due to the present acid, but I was reading this, which states: "tomach acid markedly increases dissolution and ionization of poorly soluble calcium salts. If acid is not properly secreted, calcium salts are minimally dissolved (ionized) and, subsequently, may not be properly and effectively absorbed." I have been reading a lot and realized there is someone out there who may have the answer, and would love to give it. submitted by /u/Plz_Pm_Me_Cute_Fish [link] [comments]

Biology: What causes some logs of wood to exhibit different color hues within the same tree? Posted: 20 Dec 2016 10:58 AM PST We cut down a plum tree some weeks ago when we noticed that the wood of that specific tree has two very different hues displayed in the cross section. The different colors are also very clearly separated. See images below for the logs in question. I believe to understand how tree rings are formed, so i was wondering if this case was also mostly caused by climate. Or does the color come from changes in soil or air quality? Other trees (apple) which were also cut down around the plum tree did not exhibit the same colors, so is this something specific to plum trees or a mutation? Another theory I had was that since the dark coloration is at the center, maybe it's something like the 'nutrition highway' of the tree where all the water and nutrients go through the plant? I looked up anomalies for wood, but couldn't find what I'm looking at so i hope a Biologist or even a Dendrologist could shed some light on this.

Voltage drop. How is the electric potential formula related to voltage drop? Posted: 20 Dec 2016 07:52 AM PST Correct me if I am wrong. I know that voltage drops across a resistor but I don't understand how. With the Hydraulic analogy, the increased resistance requires more voltage, but that doesn't explain what's happening with electric potential. Electric potential difference is voltage. But what causes the electric potentials to change? It has to be either the Q or r according to ϕ=kQ/r, since k is constant. But it can't be Q, because the source terminal charge isn't changing. So it must be r, right? In an electric circuit going from positive terminal to negative terminal, proton flow direction (conventional to make things easy). 1. Voltage decreases. Because for a proton to reach lower electric potential energy, it must go from high electric potential(proton source charges) to low electron potential(away from proton source b/c proton repels proton) 2. Distance from source charge, the positive terminal, increases is why voltage decreases? (using the formula ϕ=kQ/r) But in a voltage drop across a resistor 1. electrons slow down and increase in collisions, causing a distance to increase and resulting in voltage decrease? [Also, after the resistor, electrons speed back up to original current speed, since current,I, is the same before and after a resistor?] 2. this would mean the majority of the distance traveled by the protons would be in the resistors. 3. But that fails to explain how resistors in parallel have the same voltage. I understand that somehow the voltage drop is related the resistors dissipating heat from the Joule heating law P=R(I2) How is voltage drop related to the electric potential formula ϕ=kQ/r? I haven't found anything to explain this submitted by /u/tkaz44 [link] [comments]

What is the difference between Reyleigh and Tyndall scattering? Posted: 20 Dec 2016 08:01 AM PST From their wikipedia pages, I see that Tyndall scattering is specifically on particles suspended on a fluid. But why is that different from Reyleigh scattering. They both let low wavelength light pass through while scattering higher wavelength light. The Tyndall scattering wikipedia page explains that Reyleigh scattering involves smaller particles, but it doesn't cite any sources, and I don't see why changing particle size would give two distinct phenomena. submitted by /u/AbsolutelyHalaal [link] [comments]

Do metric miles change in an airplane? Posted: 20 Dec 2016 07:42 AM PST Metric miles are 1/4000th of the circumference of earth, and that's how they were established, correct? So if you increase the circumference, as you do when you increase the radius from the earth's core to you (EG when in a flying airplane), shouldn't the distance of a metric mile change? submitted by /u/tapetkabinett [link] [comments]
