Is it possible to have a dream that would permanently traumatize you? Posted: 25 Oct 2016 04:10 AM PDT There are certain things and events that can affect and damage our brain by giving us phobias, traumas and mental problems. Is it possible that dreams can cause our brain harm? submitted by /u/James64bit [link] [comments]

What in our brains causes feelings of hopelessness associated with suicide? Posted: 24 Oct 2016 08:33 PM PDT What about depression causes people to have the "hopeless" feeling that pushes so many people to suicide? Why don't we feel this while we're happy and why would our own brains be so easily led to killing itself despite the common belief while happy that suicide doesn't make sense? submitted by /u/moseph999 [link] [comments]

How do we know quantum mechanics is actually random? Posted: 24 Oct 2016 08:00 PM PDT Why is this the the belief in quantum mechanics? Why wouldn't something like the spin of an electron be determined by some hidden variables? This seems like a cop out, as if they're just saying "we can't predict it's impossible to do it". I'm sure I'm wrong though, what am I missing? submitted by /u/NoneApplicable [link] [comments]

How do Human bodies detect humidity? Posted: 24 Oct 2016 01:18 PM PDT How exactly is it done, and which body parts play a role in doing it? submitted by /u/Syyiailea [link] [comments]

What is the commonest cause of death in common laboratory mice? Posted: 24 Oct 2016 02:03 PM PDT I'm primarily interested in the commonest cause of death in mice in life-long studies in which mice are left to live out their lives without major interventions. For example, common lab mice, say a C57BL/6 strain, are placed on a normal diet and monitored until they die, what is the most likely cause of death? I think neoplasia may be the most common cause of mortality, but I'm having trouble finding sources clarifying the details. Can anyone help? submitted by /u/HolisticReductionist [link] [comments]

How can both nuclear fission and fusion release more energy than it takes to get them started? Posted: 24 Oct 2016 04:31 PM PDT From my very uninformed perspective, it seems contradictory that breaking things apart (fission) and forcing things together (fusion) would both release more energy than it takes to cause them in the first place. In other words, my intuition would be that one of them might release energy, but the other would consume it. submitted by /u/manjar [link] [comments]

Can a pure substance have more then one triple point? Posted: 24 Oct 2016 09:45 AM PDT I am aware that a triple point is a point on a phase diagram at which three phases of a substance co-exist. Is is possible for one pure substance to have more then once triple point? submitted by /u/TrynaPasss [link] [comments]

How do photons, frequencies, and quanta work? Posted: 24 Oct 2016 10:56 PM PDT How is light able to knock off electrons from metals without changing the metal in the photoelectric effect? What does the equation E=hv by Planck mean and how was it found? Where does Planck's constant come from? How can the amount of energy of a particular photon depend on the frequency of the radiation if they carry only one quantum of energy? Thank you! submitted by /u/RedditNoob001 [link] [comments]

How do you solve the puzzle?... "Let's say we have 10 quarts of milk and replace 4 quarts with cola, then stir it till its homogeneous. If it is repeated with the blend, how many times will it take to have 10% milk and 90% cola?" Posted: 25 Oct 2016 01:10 AM PDT How do you solve the puzzle?... "Let's say we have 10 quarts of milk and replace 4 quarts with cola, then stir it till its homogeneous. If it is repeated with the blend, how many times will it take to have 10% milk and 90% cola?" For example, the first replacement results in 60% m 40% c. The second replacement removing 4 quarts of the 60% m 40% c blended 10 quarts and replacing with 4 quarts c results in what new % m % c ?

How does a computer remember what programs I had open after a power outage? Posted: 23 Oct 2016 05:22 PM PDT Wouldn't programs currently running be stored in RAM? In which case shouldn't the RAM flush itself after every reboot? submitted by /u/superepicunicornturd [link] [comments]

Why does Neptune have such strong winds? Posted: 23 Oct 2016 03:42 PM PDT According to Wikipedia, it has the "strongest sustained winds of any planet in the solar system, with recorded wind speeds as high as 2,100 kilometres per hour (580 m/s; 1,300 mph)." Why are the winds so strong there? submitted by /u/jmprairies [link] [comments]

[Maths] Is there a way to break down borromean rings mathematically? Posted: 23 Oct 2016 03:35 PM PDT Although this question is specifically about borromean rings, I'm curious is you can form equations out of 3d geometry, and if you can use that to deduct the if objects would lock or intersect. submitted by /u/Weedalt [link] [comments]

Is there a chance for a number to never be rolled in a random number generator if it is ran infinitely? Posted: 23 Oct 2016 07:16 PM PDT I got into an argument with a friend of mine who is working for a random drop in a video game. He says that if he were to do the task that gives the drop infinitely he would eventually get it. I argued that since it is random and there is no pity timer that even if he rolled infinitely there is still a chance he would never get it no matter how unlikely. So who is right? submitted by /u/tongueinmybum [link] [comments]

Posted: 23 Oct 2016 01:10 PM PDT Has there been a long enough period of time since civilization to have a tangible effect on our brains? Is that something even possible to study?

When an object moves in your vision how long does the blur stay there? Posted: 23 Oct 2016 01:14 PM PDT For example, if I move my forearm about 45 degrees I'll see a blur for roughly that entire 45 degrees. If I move it for 90 degrees I'll see a blur for roughly the entire 90 degrees. However despite one motion being faster than the other, both motion blurs seem to stay in my vision for the same amount of time. How long is this timeframe? submitted by /u/Overlord_Xcano [link] [comments]

Why do spacecraft use hydrazine in their maneuvering thrusters? Posted: 23 Oct 2016 10:22 AM PDT I get the principle behind the maneuvering thrusters--equal and opposite reactions and all that. But why does it seem like they always use hydrazine? Wouldn't any old gas work? submitted by /u/Rikkiwiththatnumber [link] [comments]

Why don't the globes get dimmer as you add more globes to a circuit via parallel paths? Posted: 22 Oct 2016 11:36 PM PDT I'm currently studying my first unit in electricity in year 9. I was thinking that if you were to add many more parallel globes to an original circuit with, say, 4 parallel globes, wouldn't the amount of amps flowing into each globe be significantly reduced (as the amps need to be shared), resulting in dimmer globes? I understand that each amp carries the same amount of voltage meaning that you could add a few without much effect on the globes, but surely if the amps need to be shared, which carry the voltage, must mean less amps = less voltage per second. submitted by /u/MrOsci [link] [comments]

Is there a limit to expansion of the International Space Station? Posted: 23 Oct 2016 05:14 AM PDT There were of course cancelled modules, and I've seen some discussion of attaching private, non-state, modules to the rest of the station. If there was the funding and desire to continue using the ISS, would there be hard engineering limitations on the maximum size of habitable space that could be attached to it, or could the existing ISS be used (in theory) as a "backbone" to grow and expand on? submitted by /u/Ifkl [link] [comments]

How did we know the gravity on the moon's surface before we landed on it? What if it was much denser than anticipated and the lander didn't have enough fuel to reach exit velocity? Posted: 22 Oct 2016 08:40 PM PDT I'm guessing it's from observing its orbit and knowing its volume, but it seems really hard to get more than just a ballpark number from that. Was having a near exact figure not critically important for planning? submitted by /u/SnapesFavoriteSong [link] [comments]

Can we induce visual experiences in someone who has been blind from birth by stimulating their brain? Posted: 22 Oct 2016 05:59 AM PDT I know we can induce visual experiences in people who already have a functional visual system, for example, in this subject, or those who had a functional visual system but lost some functionality due to disease or injury. However what I am unaware of, is if it's possible to induce visual experiences in individuals who have been blind from birth, e.g. those that have no eyes, via stimulating or inducing the relevant activity in their brain. Edit: The majority of responses seem to be missing the point of my question. Perhaps I was not specific enough. The question I was getting at is, what is necessary for the having of a visual experience? It is often said that we don't "see" with the eyes because for example one can have visual experiences by stimulating the visual cortex. So from that type of finding it would seem the necessary components, e.g. the neural circuitry, for inducing visual experiences are in the cortex. If that were the case, then in theory it should be possible to create the relevant activity, either by continued stimulation directly to the cortex to create the right circuitry which would then allow for the right kind of activity, or by stimulating the circuitry that is already there, to mimic the activation pattern that is taken to be the necessary component in the generation of a particular visual experience. That is why I asked if we can induce visual experiences in someone who has been blind from birth by stimulating their brain (should have specified cortex). Because if we can, then we really can discount pre-cortical processing in being necessary for the generation of visual experiences. This might prove to be more of a technical issue, especially as we don't yet have a detailed account of the activity that is at least sufficient to generate a visual experience. However, if it isn't possible to induce visual experiences directly in the cortex, in the absence of external input through the pathway of the retina -> LGN etc., then pre-cortical processing might play a bigger role than is currently thought. submitted by /u/Laughing_Chipmunk [link] [comments]

How does fiber grating achieve mode coupling in optical fibers? Posted: 23 Oct 2016 04:23 AM PDT I've read some papers about using fiber gratings to cause mode conversion from the fundamental mode to the higher modes. I am trying to understand the physics behind the gratings. From what I gathered, it is the periodic changes in the refractive index that cause the coupling between the modes but I don't understand how it is caused. submitted by /u/mark092 [link] [comments]

What, if any, are the differences between boric acid, orthoboric acid, and borax? Posted: 22 Oct 2016 06:40 AM PDT Pretty basic question but this sub seemed the most fitting! I routinely use all 3 types, I use borax with my laundry and boric&orthoboric for ant&bug baits and dusting, but am wondering what differences, if any, there are amongst these 3 forms (if they are in fact different forms!) My curiosity was piqued when reading a product label, an ant bait product, and it said "sodium tetraborate decahydrate (Borax)", when other products on the shelf next to it were saying 'orthoboric acid' - is this stuff the same or are these different? It's disconcerting to think an insecticide is a laundry additive as well! Any help in understanding/differentiating these is appreciated, thanks guys!! submitted by /u/neovngr [link] [comments]

Does placing a non-conducting ferromagnetic material between two conductors carrying AC reduce or eliminate proximity effect? Posted: 23 Oct 2016 02:18 AM PDT Two conductors carrying AC, that are close to each other, produce a magnetic field that influences their current distribution inside each other. Will placing ferromagnetic material between them confine the magnetic field inside the material, thus reducing or eliminating proximity effect? The ferromagnetic material should be laminated or non-conductive to reduce eddy-currents. Also how will the ferromagnetic material influence the total magnetic field produced by the conductors? submitted by /u/Roikkeli [link] [comments]

ABO blood groups: do heterozygotes (ex Ao) have the same number of antibodies as homozygotes (ex AA)? Posted: 22 Oct 2016 05:18 PM PDT Basically, does having matching alleles give a bigger dose of surface antigens? Will someone with AA have more A surface antigens than someone with Ao? submitted by /u/avocadokiwi [link] [comments]

How does RF pulse affect precession of the net magnetization vector in NMR? Posted: 22 Oct 2016 11:51 AM PDT 1st question: This website and this video show that the angle of precession increases when you apply the RF pulse. However, Section 5.00 of this website shows that the cone of precession flips but the angle doesn't change. Could someone please explain what exactly is happening to the net magnetization vector? 2nd question: This website says that if the frequency of the RF pulse =/= Larmor frequency then it would precess around the Beff axis in the rotating frame. Does it mean that in the stationary frame it's precessing in 2 axes (the z axis and Beff axis) at the same time? Thank you very much. submitted by /u/chihuahuab [link] [comments]

Can TIR only occur if the second medium has a lower reflective index? Posted: 22 Oct 2016 06:47 AM PDT The formula for the critical angle is Arcsin(n2/n1), and as sin only takes values from 1 to -1, n2 always has to be smaller for it to work. Is it impossible for it to occur if n2 is greater, if so why? Or is there a different formula. submitted by /u/RavernousPenguin [link] [comments]

Evolutionarily, how is the rise of a new species not a genetic bottleneck? Posted: 21 Oct 2016 07:30 PM PDT Please correct any misunderstandings on my part. A genetic bottleneck is bad, right? It leads to defects and a lack of genetic diversity? So how are new species able to come about when the first individuals to have a certain mutation, pass it on, and lead to a split would be a small subset of the original population and therefore not genetically diverse? submitted by /u/mrembo [link] [comments]

When a modern A.I., such as IBM's Watson, "reads a book", or any other text, what is that program doing with/to that text? Posted: 21 Oct 2016 08:59 AM PDT A few weeks ago a 60 minutes piece on AI suggested that Watson read thousands of books in an incredibly short period of time. What exactly does that mean? In my mind it could be that the system is just placing it in a database? It could also mean that its running it through a filtering algorithm and assigning subject matter titles to it or plucking out supposedly important sentences? How does it process the words, sentences, and paragraph's of the work and then how it uses them later on? submitted by /u/awkpeng [link] [comments]

If a bone marrow transplant alters DNA, would a crime investigation point to two people?

Why is calculating an integral so much more difficult than calculating a derivative? Posted: 21 Oct 2016 08:52 AM PDT As far as I can tell, derivatives and integrals are inverse functions. So why is one so much more difficult to calculate than the other? submitted by /u/ohdaviing [link] [comments]

If two objects travel away from each other at slightly more than half the speed of light, does that mean they're both travelling faster than light relative to each other? Posted: 21 Oct 2016 12:10 PM PDT Also, I'm sorry if this isn't the most up to date or correct science, but changing speeds affect time, right? If one of the objects slowed down before the other, or if they both came to an instant stop, how much time would each have experienced relative to an object at the start point travelling at no speed (relative to both of them) or relative to each other? sorry if this is overly hypothetical, but it could happen in the future when we have the tech.

Is this research real progress on developing large-scale carbon capture mechanisms? Posted: 21 Oct 2016 10:40 AM PDT On the one hand, this would be great.

Melting point of carbon > tungsten? Posted: 21 Oct 2016 09:11 AM PDT So I've always believed that tungsten has had the highest melting point of all the elements, but just today in chemistry class I learned that CARBON was just above tungsten. Yet when I look up, "highest melting point element" I end up with tungsten. What's going on here? On paper carbon does seem to have a higher melting point, but tungsten is still written in as being higher. submitted by /u/adeptcroc [link] [comments]

What's the significance of a eutectic/peritectic/eutectoid point and composition? Posted: 21 Oct 2016 11:19 AM PDT It sounds an awful lot like an academic pursuit vs having any practical application. After all, a eutectic point is where liquid turns directly into two solid phases. I can't see any use in that because it's only the lowest melting point which seems like something one would want to avoid. submitted by /u/tylerchu [link] [comments]

Posted: 21 Oct 2016 06:49 AM PDT Hello, I have a question regarding dominant traits and genes, as I can understand, a dominant allene, if passed down, will always express the correlated trait in the offspring, even if there is a recessive allene passed down as well, as the Punnett square says. Let's suppose that we have several individuals with only the recessive allene that little by little take over the rest of the population never breeding with the ones having the dominant trait, so that only the recessive allene is passed down in the end, will the dominant trait eventually disappear completely? Even if there is the case of only the recessive allene present in the population, is it still correct to call it a recessive trait? Am I missing something? submitted by /u/ISpokeAsAChild [link] [comments]

I know that if you repeat a set of moves on a rubik's cube it will eventually return to it's original state. How would this work if one or more side was infinitely long? Posted: 21 Oct 2016 01:58 AM PDT Could you have infinately long sequences that still return and if so would all sequences still "loop" even though you have to repeat an infinitely long sequence infinitely many times? submitted by /u/stromgr1 [link] [comments]
