According to an article engineers have created a 1nm transistor, the article said they used molybdenum disulfide because it has "heavier electrons" that don't suffer quantum tunnelling, what do they actually mean? Surely electrons are electrons? Posted: 10 Oct 2016 06:05 AM PDT Here is the article http://hexus.net/tech/news/industry/97837-berkeley-lab-researchers-create-transistor-1-nm-gate/ and the paragraph in particular Berkeley Labs refers to molybdenum disulfide (MoS2), commonly used as an engine lubricant, as its other key material. While electrons travelling through Silicon gates of under 5nm would be "out of control" due to a quantum mechanical phenomenon called tunnelling, the heavier electrons in molybdenum can be controlled with these smaller gate lengths. Furthermore MoS2 can be scaled down to atomically thin sheets, of about 0.65nm thick. submitted by /u/rmcleod79 [link] [comments]

Is atomic resonance a constant or does it depend on gravity/forces? Posted: 09 Oct 2016 07:07 PM PDT So, my cousin got a kinectic watch and we started discussing on how exact a watch (or any timekeeping device for that matter) could get. I mentioned how the atomic clock is the most accurate watch in existance blah blah, and that it counts the osciliation of cesium blah blah, but he mentioned that the resonance could change depending on the forces acting on it. Is it true, partially or not? (please note I am no physics expert, i'm still on middle school :p probably I wrote a thing or two wrong) submitted by /u/GamerGab007 [link] [comments]

How do ants deal with heavy rainfall and hurricanes in tropical regions? Do they somehow waterproof their colonies? Posted: 09 Oct 2016 03:33 PM PDT So this question sparked a debate between me and my parents while prepping for the arrival of Hurricane Matthew last week. We have a modest population of fire ants in our backyard, and seeing as it's been raining nearly every day for the past couple months here in Florida, I figured the ground would already be saturated with water. Having heard about how ants join together to make ant rafts during floods, I suggested we buy ant traps as a last line of defense in case an ant raft floated our way. The hurricane came and went, as did a torrent of water which temporarily submerged our backyard. The ants are already back in their regular location, and they're making repairs to their mounds on the surface. How bad might the destruction have been underground? Did the ants evacuate, or did they take shelter in their colony? Do their chambers flood and/or collapse? Any and all insights into these fascinating creatures is welcome. submitted by /u/OmniscientTexan [link] [comments]

How does the holographic principle make sense, if the universe actually has no boundaries? Posted: 09 Oct 2016 12:00 PM PDT As far as I understand it, watching this Leonard Susskind interview, the holographic principle states, that all information in the universe isn't proportional to the volume of the universe but to its boundaries. All information can be stored on its boundaries - just like all information of a black hole can be stored on its event horizon. Okay. I kind of get the black hole thing. But if the universe has no boundaries (the ant on the ballon and all) how does this even make sense? Does it have boundaries the human brain is just incapable of imagining? I'm completely lost putting these two ideas together. submitted by /u/JonOstermann [link] [comments]

Is the graviton believed to exist or is it purely hypothetical? Posted: 09 Oct 2016 08:16 AM PDT I only ask because my Physics teacher often talks about it as if it is the force carrier of gravity when from my understanding there is no evidence of its existence. submitted by /u/iCaird [link] [comments]

Does indium attack aluminium in the same way that gallium does? Posted: 09 Oct 2016 08:20 AM PDT This, of course, is assuming that you can somehow keep it molten for long enough. submitted by /u/MuzikBike [link] [comments]

Why are oxidized compounds typically in a lower energy state? Posted: 09 Oct 2016 02:01 PM PDT When methane is oxidized into co2, it releases a large amount of heat. This implies that the total heat of formation of co2 and water is significantly lower than that of methane. Why is this the case? submitted by /u/PittleBoLeep [link] [comments]

Do supposedly silent letters have any effect on pronunciation? Posted: 09 Oct 2016 04:10 PM PDT I've noticed that when I say "night" and "knight", in saying the latter it's almost like I feel that 'k' there. Like not pronouncing it but I know it's there. I've noticed similar in other silent letters. Is there any actual measurable slight difference in words with silent letters like that, or is it all in my head? submitted by /u/alfrednachos [link] [comments]

What are some examples where scientific knowledge/innovation was influenced by traditional healing methods? Posted: 09 Oct 2016 12:09 PM PDT To clarify, I'm asking for examples where some new scientific innovation was brought about by studying tribal (traditional) healing practices. I know that they have been using specific plants, drink, food, etc as a form of healing that is passed down each generation. So has any form of drug or innovation been discovered by studying these practices? submitted by /u/Thomas_Pickles [link] [comments]

How can we know the Sun's surface temperature when the Sun's corona around it is hundreds of times hotter? Posted: 09 Oct 2016 07:48 AM PDT I read today about the fact that the Sun's corona is hundreds of times hotter than the photosphere (surface) of the Sun. The photosphere measures around 6000 K, goes over 20,000 K in the chromosphere and way over 1 million K in the Sun's corona. As I was glad to learn something new, my little science brain started thinking about how we can possibly measure 'lower' temperatures that's surrounded by such extreme high temperatures? The problem I'm visualizing, is like measuring the heat of a warm coffeecup that is hidden behind a larger, hotter campfire (or something hotter). Maybe a bad analogy, but I'm curious about the temperature measurement techniques used if it's explainable in ELI5 format :) submitted by /u/gunnar_osk [link] [comments]

Why do we need to continually consume protein? Posted: 08 Oct 2016 10:25 PM PDT Isn't protein used to build molecular structures using the amino acids? Why don't our bodies just recycle the ones we have if we aren't growing or trying to bulk up? submitted by /u/DippyTheDinosaur [link] [comments]

How do lysosomes in phagocytes know only to attach to *food vacuoles*, and not simply affix themselves to the interior of the cell and eat that? Posted: 08 Oct 2016 03:11 PM PDT I assume the new vacuole is created with a phospholipid bilayer analogous (if not identical) to the cell membrane that was just used to eat whatever was engulfed. Is it simply the hydrophobic nature of the outside of the vacuole that draws the lysosome over like some sexy hooker and is like "hey stud. you look like you're pretty hungry. why don't you come over here and take a bite outta this ass?" ^ (pretty sure that's how it happens scientifically.) submitted by /u/Ungodlydemon [link] [comments]

When packet loss occurs, are the packets truly being "lost", or are they simply fading into the background? (Computing) Posted: 08 Oct 2016 09:09 AM PDT My father and I are having a discussion about packet loss in computers. We're essentially arguing about semantics. When packet loss occurs (assuming no mal-intent by others), is the packet not arriving at it's destination, or is it arriving but at such a low signal that the receiver cannot distinguish it from noise? submitted by /u/Iced_Bacon [link] [comments]

Does a polyhistidine tag alter the folded structure of proteins? Posted: 08 Oct 2016 03:11 PM PDT From what I understand, the function of a protein generally relies on its folded structure. It seems like adding a poly-His tag is a common way of separating out a synthesized protein from the rest of the natural proteins, after which the poly-His is cut off enzymatically. Do most proteins have only one stable folding pattern, which they fall into when the tag is cut, or is it often the case that the resulting protein is now misfolded? If so, is there some way of ensuring the folded structure is actually the same as the normal folded structure? Is there a collection of proteins for which the poly-His approach does not work, because the tag alters the shape of the protein? The question really comes from a fundamental question about proteins: do most proteins have a single, stable structure (in water, at physiological pH), or are there frequently multiple stable structures? Techniques like poly-His tags seem to suggest that it is the former, while discussions of protein function (eg prions, bohr effect in hemoglobin) seem to rely on the latter. submitted by /u/hansn [link] [comments]

If factoring numbers with ~1000 digits is so difficult that it is used in encryption, how do we know of primes with many millions of digits? Posted: 07 Oct 2016 12:15 PM PDT I know that certain cryptographic systems use large prime factorizations as their encryption method because it takes a long time to factor large numbers, and using numbers with 1000+ digits produces an encryption that is nigh-unbreakable with current technology. So how is it that the largest known prime has over 20 million digits and we know of many prime numbers with millions of digits, if factoring numbers is so difficult? submitted by /u/lucien15937 [link] [comments]

How do calculators evaluate the zeroes of polynomials? Does it depend on the nature of the polynomial? Posted: 08 Oct 2016 06:00 AM PDT Hello, I'm curious to know how my calculator (it's a Casio) calculates the roots to polynomials. I would guess for quadratics, it uses the formula, and probably for cubics and quartics. But above that, there are no general formulas, so it has to use approximate methods somehow. What approximate methods do calculators use for root-finding of polynomials, and what degree of polynomials do they use them for? (Would a 4th degree polynomial be evaluated with an approximate method, or the monstruous formula?) Thanks! submitted by /u/tsterTV [link] [comments]

Is the role of pressure vs. concentration gradient for gas solutions the same as it is for liquid solutions? Posted: 08 Oct 2016 05:50 AM PDT Let's say you have two equal volume, equal temperature chambers separated by a semipermeable membrane: In the left chamber there is pure oxygen at 2 atmospheres of pressure. In the right there is pure nitrogen at 1 atmosphere of pressure. The membrane is only permeable to nitrogen. What happens? Is it similar to the usual osmotic pressure teaching example? Does the nitrogen diffuse into the left chamber increasing the pressure gradient until it counteracts the diffusion gradient? submitted by /u/gmieom [link] [comments]

How does Asymetric Encryption actually work? Posted: 08 Oct 2016 05:30 AM PDT Hello Reddit, I learned about encryption using asymetric keys a few years ago, but never truly understood it. I get that (for example) I have a public key and a private key and then you also have your own public key and private key; that if we swap public keys that I can encrypt a message using your public key that you can decrypt with your private key; but in the end, it all still seems like a magical black box. What would this look like in the real world? Are there any more "tangible" examples not in cyberspace?? Thanks! submitted by /u/SandShepherd [link] [comments]

How do modern game clients allow you to play a game before its finished downloading? Posted: 08 Oct 2016 01:10 AM PDT Recently, Origin (EA) and Uplay (Ubisoft) have gotten a new feature. Whenever you download a game, you can play it whilst it is downloading, as soon as it gets past a certain percentage downloaded. For example, I was downloading a racing game called "The Crew" and I could play the game as soon as 10% of it had downloaded, without installing anything, and the quality seemed just fine. How does this work? It is blowing my mind. submitted by /u/Urnquei [link] [comments]

What are some strange things that happen under EXTREME magnetic fields? Posted: 07 Oct 2016 09:48 AM PDT I was reading about the magnetar SGR 1806-20, which has a magnetic field of 1015 Gauss (1011 Tesla in intensity) . The article said that if this magnetar were as close as the moon to Earth, it could re-arrange the molecules in your body.

But what if you only wanted to track small moving objects, like a ball or a person, within a 1000 foot radius? Is that possible with radar? If not, could you explain why? If yes, would the radar device need to be large, or could it be made into a handheld device? Radar is very cool, and reading the question prompted deeper questions. :) Thanks so much! submitted by /u/panabee [link] [comments]

A planet sized ball of water - what would happen? Posted: 07 Oct 2016 01:54 PM PDT Say you had a planet sized ball of water entering the solar system from interstellar space to take up an orbit between Mars and Earth. Something approximately double the size of Earth, and all it was made of was pure H2O. No impurities, no residual trace elements, literally nothing else. What would happen? Would it be frozen just on the outside, or all the way down to it's "core"? Would the core experience fusion? Would the outer layer be frozen solid, and then there be a liquid inner layer, and then finally a solid inner layer because of pressure? What would happen? Any thoughts would be greatly appreciated. Thank you. submitted by /u/VertigoOne [link] [comments]
