How is personality formed? Posted: 07 Jun 2017 06:15 AM PDT I came across this thought while thinking about my own personality and how different it is from others. submitted by /u/FlamesDoHelp [link] [comments]

Why do anxiety and depression often occur together? Posted: 06 Jun 2017 07:20 PM PDT I have seen many people who struggle with both depression and anxiety. I don't have anxiety. I can't bring myself to care about tomorrow, I'm too busy trying not to die today. Why do these two seemingly arbitrary things so frequently show up in the same people? submitted by /u/EdragonX [link] [comments]

I have recently come across the notion of "Nice guy syndrome"; is this a well established concept in current psychological thinking or it fringy? Posted: 07 Jun 2017 04:05 AM PDT example: http://www.peopleskillsdecoded.com/nice-guy-syndrome/ submitted by /u/Gargatua13013 [link] [comments]

How does genetic variation and evolution happen in hermaphroditic organisms that have both female and male reproductive organisms? Posted: 06 Jun 2017 08:10 PM PDT In an organism such as a hermaphroditic fluke (flatworm), how does genetic variation get introduced to the genome? Since they basically have sex with themselves, how can these organisms continue to evolve? Is it exclusively due to chromosomal cross over that happens during gamete formation? submitted by /u/Doren17 [link] [comments]

How does the structure of protein, fat, and carb molecules change how they affect our bodies? Posted: 07 Jun 2017 05:38 AM PDT such as the way a pound of fat is much larger than a pound of protein. What causes this difference? submitted by /u/Diskercader [link] [comments]

Why does ice break in a hexagonal pattern? Posted: 06 Jun 2017 06:50 PM PDT This post spurred a discussion about why the ice in the photo breaks out in six directions. Does it have anything to do with the molecular structure of H20 or is it purely coincidental? submitted by /u/radio934texas [link] [comments]

What happens to (small) bugs during rain? Posted: 06 Jun 2017 03:28 PM PDT I'm serious. Right now, it's mosquito season where I live, which results in me drowning them occasionally when I wash my hands and they are in the sink and such. These smaller bugs, with lithe bodies drown quite easily, or even if they don't die, they can't fly or get "paralyzed" for some time. Right now, it's also raining where i live. And there aren't any mosquitoes or other bugs in my room, which is usually full of them. So I was wondering, do mosquitoes or other bugs that don't love next to waters have built in water defense mechanisms, or are they just really good at hiding? submitted by /u/Annabanaana [link] [comments]

Airplane oxygen masks - bag does not inflate? Posted: 06 Jun 2017 06:15 PM PDT During the pre-flight safety instructions, the passengers are explained how to take the oxygen masks on. It is also mentioned that the bag will not (might not) inflate. I am just wondering, why is the bag there to begin with? One answer might be to reduce the pressure, but the mask does not fit tight, so air would flow out easily. submitted by /u/caversluis [link] [comments]

Do we know what weather was like on Earth during Pangea? Posted: 06 Jun 2017 08:00 AM PDT Or any other time our land masses had a different formation. I was thinking about the potential for storms and assumed that there could have been a way for storms to get massive in size whether for a short or long period of time. It is cool to think about the potential of super storms if all the right ingredients easily come together due to water currents, air flow, etc. submitted by /u/Dalem5 [link] [comments]

Why is it so difficult to eliminate microphone feedback? Posted: 07 Jun 2017 07:51 AM PDT 'Feedback', as I understand it, is essentially the microphone picking up the noise generated by the speakers, which is then amplified, emitted by the speakers again, picked up by the mic, amplified, and so on in a destructive cycle. It seems to me it should be simple from a signal processing perspective to just have the microphone filter out whatever sounds the speakers create to eliminate this feedback loop. So why is it still so challenging to implement and why is feedback still so ubiquitous? submitted by /u/chejrw [link] [comments]

Could the laws of conservation of linear and angular momentum be explained in terms of the law of conservation of energy? Posted: 07 Jun 2017 07:29 AM PDT Thanks in advance submitted by /u/Luke042able [link] [comments]

How do particle accelerators work? Posted: 06 Jun 2017 07:45 PM PDT Kind of wanting to build a small one, if possible, just want to know what goes into one submitted by /u/Megatryst [link] [comments]

Why did early humans not get constantly sunburned and die of skin cancer? Posted: 06 Jun 2017 07:33 PM PDT Thought of this as I got severly sunburned after like 4 hours in the sun on Sunday. submitted by /u/Maybe_llamas [link] [comments]

What determined the size and shape of the tectonic plates? Posted: 07 Jun 2017 05:43 AM PDT I was just thinking about plate tectonics, and how they have driven the shape of the world as we know it, but I don't understand why the boundaries between them formed where they are. I guess my question could be rephrased as 'Why are the plate boundaries where they are?' submitted by /u/LacunaMagala [link] [comments]

[Astronomy] Since our solar system is moving at such great speed; why is there no trailing blaze of fire after our sun, or any star for that matter? Posted: 06 Jun 2017 07:42 PM PDT submitted by /u/caprizoom [link] [comments]

How should a layperson decide whether to trust a psychology study? Posted: 06 Jun 2017 10:10 AM PDT The question obviously applies to all fields of science, but I was particularly interested in psychology studies after having looked at this paper demonstrating that you can actually become younger after listening to a Beatles song. I was prompted to look at the study because of this article on Daryl Bem and his ESP studies. The idea behind the paper and article is that there are problems with how these kinds of studies are done. As someone outside of the sciences, I have no tools to evaluate whether or not I should take this kind of work as being relevant or trustworthy. Where should this leave a lay audience, who will see a link to a peer-reviewed journal article and then assume that there's evidence to back up an assertion? submitted by /u/sleepstandingup [link] [comments]

Why does a concussion prevent you from donating bone marrow? Posted: 06 Jun 2017 11:57 AM PDT I was looking on this website. Why would this disqualify someone from donating? submitted by /u/fpga_wut [link] [comments]

How common is general anesthesia in dental practice? Posted: 06 Jun 2017 01:07 AM PDT Regional anesthesia is used the most in my area despite the difficulty of the dental procedure (pulling wisdom teeth for example). General anesthesia is the last option and barely suggested. So how common is general anesthesia in dental practice in other countries? submitted by /u/zulzulfie [link] [comments]

Are there video algorithms to significantly enhance detail from low quality RAW video source material? Posted: 06 Jun 2017 04:20 AM PDT Everybody knows the stupid TV trope, where an investigator tells his hacker friend "ENHANCE!", and seconds later the reflection of a face is seen in the eyeball of a person recorded at 640x320. And we all know that digital video does not work like that. But let's say the source material is an analog film reel, or a feed from a cheap security camera that happened to write uncompressed RAW images to disk at 30fps. This makes the problem not much different from how the human eye works. The retina is actually pretty low-res, but because of ultra fast eye movements (saccades) and oversampling in the brain, our field of vision has remarkable resolution. Is there an algorithm that treats RAW source material as "highest compression possible", and can display it "decompressed" - in much greater detail? Because while each frame is noisy and grainy, the data visible in each frame is also recorded in many, many consecutive images after the first. Can those subsequent images be used to carry out some type of oversampling in order to reduce noise and gain pixel resolution digitally? Are there algorithms that automatically correct for perspective changes in panning shots? Are there algorithms that can take moving objects into account - like the face of a person walking through the frame, that repeatedly looks straight into the camera and then looks away again? I know how compression works in codecs like MPEG4, and I know what I'm asking is more complicated (time scales longer than a few frames require a complete 3D model of the scene) - but in theory, the information available in the low quality RAW footage and high quality MPEG4 footage is not so different, right? So what are those algorithms called? What field studies things like that? submitted by /u/pbmonster [link] [comments]

For people in areas with no access to clean water, do they live with constant parasite/bacterial infestations or do their immune systems become adept at clearing them? Posted: 06 Jun 2017 06:24 AM PDT Just got back from my second trip to Haiti. Got Giardia...again. It had me thinking, for the people that live where I went they are obviously exposed to the cysts on a daily basis. Are they living with the parasite and e coli infections all day every day? Or do their body's immune systems become adept at fighting off the parasites and e coli so that infestations can no longer occur? Follow up question: I read that Giardia cysts can last for months, are cold resistant, and resistant to chlorination and UV disinfectants. That being said, when I go to the bathroom, how is our wastewater treatment eliminating the cysts? Or am I just flushing my problem down to someone else later on? submitted by /u/MangoManchild [link] [comments]

Can two consecutive frames from a camera be exactly the same? Posted: 05 Jun 2017 04:09 PM PDT If I'm running a video camera on an extremely still scene (eg. in my living room where there is no wind) and I grab two consecutive frames, is there a possibility of both frames being totally identical? By identical, I mean each pixel is the exact same color, and they both have the exact same checksum when saved to a file... submitted by /u/hannibaldon [link] [comments]

Is a nonlinear system truly indeterminable? Posted: 06 Jun 2017 05:47 AM PDT I've been thinking a lot lately about determinism from a physics standpoint: if we disconsider Quantum Physics, wouldn't everything be pre-determined? If all there is are atoms and we can predict the next state of the system based on the current one, technically the future is already known. Of course, with Quantum Physics the future would be nothing but probabilities. But then I've heard about complex, nonlinear systems, which the human brain would be an example. They're described as being unpredictable and that the state before doesn't necessarily dictate the state after. How can this be? Are nonlinear systems just something that is affected by many variables and it's virtually impossible to account for all of them? However a hypothetical all-knowing creature that had all the information would be able to predict the next state? Or is it truly chaotic? submitted by /u/fevieiraleite [link] [comments]

Why don't we induce artificial gravity on space stations with a rotating section? Posted: 05 Jun 2017 02:07 PM PDT This is something I've been asking myself for a while: the absence of gravity (eg on the ISS) causes problems to astronauts like muscle volume reduction. If one of the parts composing the ISS were rotating, it would induce a gravity-like force pulling radially, that would allow the astronauts to at least exercise passively. Due to low friction, maintaining the rotation wouldn't be expensive. I'm curious to know why this isn't practical. My guess is that maintaining the sealing between the rotating and noon rotating parts is not as trivial, but again one could "pack" everything. submitted by /u/UserAlreadyNotTaken [link] [comments]

If we remove one by one elements of natural numbers infinitely many times, will we ever empty the set? What about reals? Posted: 05 Jun 2017 11:41 AM PDT Let me explain, the key here is that you remove numbers infinitely many times, you don't stop at one moment. My guess is that if the set is countably infinite we can achieve removing every element because we removed countably infinite numbers from the set and we can construct a bijection from the elements removed to the natural numbers, so there is no room left for another number; but if it is not countable, there is not even a way from where to start removing elements so we wouldn't reach an end(or even a start), am I right? What is the correct answer for this? submitted by /u/PeriferialGuy [link] [comments]

Why do some photons pass through a mirror? Posted: 05 Jun 2017 02:42 PM PDT I had once watched a very interesting youtube video which explained this in detail, but I forgot the reasoning & can't find the video. If someone can find it, I'd love to re-watch! submitted by /u/sloppies [link] [comments]

How much mass is travelling in the LHC when it is on? Posted: 05 Jun 2017 03:06 PM PDT Like the title says, when the Large Hadron Collider is operating, how much does all the particles traveling in it weigh(combined)? submitted by /u/Tuxinet [link] [comments]

Why is Beryllium-8 Unstable? Posted: 05 Jun 2017 10:25 AM PDT Helium-4 (an alpha) is super-stable. So is Carbon-12, which can be viewed as merely 3 alphas. So are Oxygen-16, Neon-20, Magnesium-24, as 4, 5, and 6 alphas, respectively. Each of these elements can be viewed as merely a pile of alphas, and all but Be8 are all stable, and given my limited, hand-waving understanding of nuclear physics, it makes sense: Nuclei "like" even numbers of nucleons, even numbers of protons & neutrons (an even-even nucleus), and a comparable number of protons to neutrons, which all of these nucleii have. So why is Be8 the outlier? Get your shit together Beryllium-8! submitted by /u/garrettj100 [link] [comments]

What IS potential energy? Posted: 05 Jun 2017 03:01 PM PDT One that always bothered me is the concept of potential energy. It is said that is energy stored in an object with the famous example of the ball and gravity, but that doesn't seem to make any sense at all it seems as if it is just a term used so that the law of conservation of energy is true. So what is it? How do we know it is a thing? submitted by /u/Kemo-III [link] [comments]

How accurate are laminar boundary layer models? Posted: 05 Jun 2017 11:47 AM PDT I have just finished my second year of university with a module in fluid dynamics in which Laminar boundary layers with zero pressure gradients were looked at. As part of this module, boundary layers with adverse pressure gradients that looks at separation of flows were also looked at. My question is, how accurate are the models that assume u/U=n-n2 for example where u is the velocity,U is the free-stream velocity and n is the ratio (y/delta) and obtaining solutions based on the no-slip conditions for example. Thanks! submitted by /u/spk96 [link] [comments]

Do time crystals imply CP violation? Posted: 05 Jun 2017 07:06 PM PDT I know they can exhibit spontaneous T-symmetry breaking, so does that in turn imply CP-symmetry violation? Pardon me if I misunderstand the notion. submitted by /u/BackburnerPyro [link] [comments]

Are there any liquids that are less viscous than water? Posted: 05 Jun 2017 08:20 PM PDT Looking and the small waves in my pool the other night cause by very slight breezes provoked this thought as it seemed very little force is needed to get a lot of water to move. No better place to ask then here! submitted by /u/mojoespo33 [link] [comments]

Hummingbirds flap their wings around 70 times per second during normal flight...what is the fastest natural movement that humans are capable of, either voluntary or involuntary? Posted: 04 Jun 2017 07:48 AM PDT My daughter was watching a cartoon on PBS this morning and they were talking about pollination. It was mentioned that hummingbirds are capable of flapping their wings upwards of 200 times per second. After a quick google, it seems 70 is the more common number for "normal" flight. That's obviously still extremely fast and made me wonder what humans are capable of in terms of pure speed, so I thought I'd ask here. submitted by /u/imTHATitguy [link] [comments]

what, precisely, is the difference between a dipole-dipole interaction and a "hydrogen bond"? Why is a hydrogen bond (a) different and (b) stronger? Posted: 05 Jun 2017 05:08 AM PDT People typically just give the reason that it's the electronegativity difference. But that's wrong - HCl does not show hydrogen bonding - just look at the boiling points - it's very clear that only HF, H2O and NH3 have hydrogen bonding here. There's a huge offset from the rest of the trend because of them. CLEARLY the electronegativity is not the full story, because HCl is not showing anything off-trend in that plot, yet has a bigger electronegativity difference than NH3 does. I went down the rabbit hole of thinking it was because it had to be period 2 elements - because then they were smaller and therefore had a better orbital overlap with hydrogen, creating a stronger bonding interaction. But NOPE. That's not the explanation either. I found some chem papers floating around that are talking of hydrogen bonding in H2S. WTF? I look on wikipedia and see that hydrogen bonds are supposedly why water gets such a high boiling point whereas H2S doesn't, because H2S doesn't hydrogen bond. Um. GUYS. Does it or doesn't it?? wtf even IS a hydrogen bond anymore?? if it's just a dipole-dipole thing then why have its own name??! and what's the deal with water's boiling point?? if it ISN'T just that then what IS it? what differentiates it? I find it maddenning that literally nowhere clarifies this. All it EVER says is lists molecules that hydrogen bond and ones that don't, and states NO REASON why those specific ones do or don't or what the flipping difference is supposed to be. WHATS THE DIFFERENCE? FOR example. How do I tell whether the electrostatic interactions in HS are hydrogen bonding or not? BEYOND something vacuuous like "oh it's a sulfur therefore we don't call it that". There are papers out there that DO call it that. submitted by /u/usernumber36 [link] [comments]

Has the string theory been validated by any experimental evidence like from the LHC? Posted: 05 Jun 2017 03:45 AM PDT Are there better contenders for the theory of everything?

I come from a medical background, so please excuse any gross misunderstandings of the concept. submitted by /u/zorbix [link] [comments]

What's the current state of Thorium Molten Salt Reactor research? Posted: 04 Jun 2017 09:46 AM PDT From time to time talk about Thorium / Molten Salt Reactors pops up as possible solution to our energy problem. As far as I can see it's far away from being well-funded research nowadays. Can someone explain why we put billions into fusion reactor research and not closely enough into Thorium / Molten Salt Reactor research? Also: What is the current state of research? How far would we realistically be away from having such reactors? submitted by /u/hdsjulian [link] [comments]

How common is prion resistance/immunity in humans? Posted: 04 Jun 2017 09:21 AM PDT I have general anxiety disorder, and recently I have been losing sleep over a prion phobia. So, how common is genetic resistance to prion disorders in humans? Specifically, my family is of southern Chinese background, and I would like to know if prion resistance would be common in a typical southern Chinese genotype. Thank you. submitted by /u/HappyDaysInYourFace [link] [comments]

How are percent chances of rain, storms, etc. determined? Posted: 04 Jun 2017 05:26 PM PDT I'm curious to learn how those percentages are determined, and why they vary from station to station. I also would like to know why we can't be more exact and how "surprise" storms occur with little to no warning. submitted by /u/knine1717 [link] [comments]

Does increasing orbital angular momentum cause electromagnetic radiation to travel slower through a material?

What happens when Thermite burns asphalt? Posted: 04 Jun 2017 05:03 PM PDT I was watching videos on the Battle of Britain, more so memoirs of those involved.

Even if not historically true, what would happen to Asphalt when burned by thermite? Thanks submitted by /u/Toads45 [link] [comments]

Does the density of air change in a controlled volume, if we change the temperature inside the box? Posted: 04 Jun 2017 08:21 AM PDT Since density is mass over volume, and the mass isn't changing, and the volume isn't changing, does the density of air not change? submitted by /u/bush_did7-11 [link] [comments]

Can energy be generated through the color force? Posted: 04 Jun 2017 06:04 PM PDT Generating usable energy seems to be done by exploiting one of the four fundamental forces. Gravity can be harnessed by dams, electromagnetism by chemical reactions such as the combustion of gasoline, the weak nuclear force through fission, and the strong nuclear force through fusion. I realize that the strong nuclear force and color force are fundamentally the same interaction, but they are distinct. Matter can be created by applying energy trying to separate quarks due to confinement, is the reverse possible? submitted by /u/mattbros [link] [comments]

How does the huge arch over Chernobyl work? Posted: 04 Jun 2017 09:43 AM PDT How does it keep radiation from getting out?

Will denser objects sink forever? Posted: 04 Jun 2017 02:00 AM PDT If you hve an infinite column of water and place an object denser than water in it, will that object sink forever? I don't think it will because if pressure inside the water is pgh, then there must be some height h where the pressure balances out the pressure exerted by the object and the water on top, right? Say water area is A, density is 1, and height is H. And object area is A, density is 2, and height is h. And gravity g is 10. So if the object is in the water, it displaces the water on top. So now there is water on top of the object, and the water below the object feels the force of both weights. Force of water on top of object is 1AH*g = 10AH. Force of object is 2Ah*g = 20Ah Adding both forces gives 10AH + 20Ah. Pressure is force/area, so we get (10H + 20h) for pressure. Is there any height in the water column that will support this pressure and prevent sinking? submitted by /u/yosimba2000 [link] [comments]
