At what taxonomical level do we begin to observe valves in veins? Posted: 17 Feb 2017 08:59 PM PST I was watching this video on hearts when I saw that the venous structure diagram did not show valves (see here). At what taxonomical level do valves arise? I know that vertebrates tend to have closed circulatory systems whilst invertebrates can also have open ones (though "vertebrate" and "invertebrate" are not accurate taxonomic distinctions). I do not know, however, when the structure of veins begins to diverge. That's what I'd like to know. submitted by /u/De_dato [link] [comments]

Can a bagel be cut into Borromean rings? Posted: 17 Feb 2017 08:48 AM PST A video has been going around lately showing that a bagel can be cut into two linked rings if you cut along a Mobius band. In theory, with an additional cut, we could produce three linked rings. And obviously, with a bunch of cuts you could trivially carve a set of Borromean rings out of a bagel. But it got me wondering, is there a way using two cuts to slice a torus into three (or more) Borromean rings? My suspicion is that it can't be done, but I'm not sure how to go about proving or disproving this. submitted by /u/quatrevingtneuf [link] [comments]

Why can't we target beta amyloid plaque with ubiquitin? Posted: 18 Feb 2017 01:10 AM PST I'm learning about how proteins are targeted for destruction using ubiquitin and how these proteins are subsequently torn up by molecular machines called proteasomes. If plaques are predictable because of how they are cut up and aggregate together, why can't we tag them with ubiquitin and allow proteasomes to eat away at them? submitted by /u/Humes-Bread [link] [comments]

How does Boron's ability to absorb neutrons work and does absorbing neutrons affect the atom? Posted: 17 Feb 2017 10:22 AM PST Boron is often used in nuclear reactors because of its ability to absorb neutrons. How can Boron do this without becoming super heavy or otherwise changing itself? submitted by /u/techNerd89 [link] [comments]

Why is hydrochloric acid a covalent compound, and why is it still named as hydrogen chloride? Posted: 17 Feb 2017 08:42 PM PST Although I've read that all acids are ionic as they break into a hydronium ion in solution, hydrochloric acid has a polar covalent bond and is classified as covalent, even though it's named hydrogen chloride. Could I ask for an explanation for why it is not ionic even as an acid, and why it would still be named hydrogen chloride? I couldn't find an explanation online. submitted by /u/Natsu_Hime [link] [comments]

What holds a cloud together? Posted: 17 Feb 2017 08:38 AM PST When i smoke and breath out a cloud it gets dispersed fairly quickly, even inside where there is no wind. Now I know that they are always changing but sometimes you can watch a cloud move all the way across the sky looking like the same cloud. Why dont they constantly disperse and form into new clouds due to winds/other forces? submitted by /u/b-crew96 [link] [comments]

Is there a charge for the weak force? Posted: 18 Feb 2017 01:43 AM PST The other three fundamental forces all seem to have charges which act as sources and/or sinks of flux. Electromagnetism has electric charge, gravity has mass and the strong force has colour. So is there a charge for the weak force? submitted by /u/nottherealslash [link] [comments]

i have various questions about black holes? Posted: 17 Feb 2017 08:39 PM PST I've tried googling for these answers but the links online tend to be pretty hardcore science and math related. I'd be grateful if I could get the answer without it being overly complicated. Please and thanks! So let me give my understanding of a black hole and then I'll ask the things I'm confused about. And please also correct me where I'm wrong. My understanding is that a black hole is caused by any body that has been shrunk to a degree that has caused an enormous amount of density. This now exerts an enormous amount of gravitational force within a specific radius, so large that even light can't escape. I believe this doesn't technically have to be an old star but practically speaking that's the only way it'd happen, for a star to die. Am I correct so far? Here's the questions I have: What is the volume of a black hole? I've wondered this for years and never got a straight answer. When googling around I used to get math rather than a straight answer. My latest understanding was that the volume was zero and this is called the singularity. But just yesterday I read about a supermassive black hole in the phoenix cluster that seemed thousands of times larger than our solar system. I'm not referring to mass (though the mass was 20 billion times our sun) I'm referring to volume. Actually is volume technically the correct term? What exactly is the Singularity, the Schwarzschild Radius, and the Event Horizon? My understanding of the Event Horizon is that it's the edge of space a specific radius from the hole where nothing can escape, not even light. Correct? But I also know that gravity is a function of mass. The sun's gravity doesn't affect astronauts in space because they have minimal mass but it affects pluto which is soooo much further away because pluto's mass is so much more. So if that's correct then while light may be able to escape from the edge of the event horizon, if you were to put, say, a paperclip a foot away from it that would probably get sucked in, right? If you were to put a human a mile behind the horizon I would guess that would also be sucked in. So it seems like the event horizon only measures what light can escape and is a fairly random thing outside of that. I dont see the relevance. EDIT - I just googled the Schwarzschild Radius. The explanation was simpler than I expected. But the explanation I'm seeing makes it sound like the definition of an Event Horizon to me The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is the radius of a sphere such that, if all the mass of an object were to be compressed within that sphere, the escape velocity from the surface of the sphere would equal the speed of light. submitted by /u/ZiggyZig1 [link] [comments]

Is Hyper Ionization of Large Elements Possible? Posted: 17 Feb 2017 11:31 AM PST By this question I mean taking a large element like uranium and stripping away ALL of its electrons not just the valence electrons. If so is there a size limit to the elements before the nucleus has too great of a positive charge to let all the electrons go? submitted by /u/Wooglepook [link] [comments]

What are the benefits from discovering only a few atoms of elements like 118 (Oganesson) and others that were created in an accelerator? Posted: 17 Feb 2017 07:22 AM PST Certain man-made elements like Tennessine (117) or Oganesson (118) have been created in a particle accelerator but only a few atoms detected at a time. If we cant physically do anything with these new elements, what are the other benefits from creating/discovering them? And whats the importance of synthesizing others like element 120? submitted by /u/BSJones420 [link] [comments]

Why isn't set-builder notation used for defining functions? Posted: 17 Feb 2017 01:33 PM PST In set-builder notation, we use | to show givens, yet there isn't really a standard symbol to show givens when defining functions. But when we define functions, there's no real standard notation to show conditions for the function. For example, if f(x)=x-1, some may write this as: f(x) = x-1, x != 0 or f(x) = x-1 st x !=0 or f(x) = x-1 gt x != 0 So why don't we just import the symbol from set-builder notation so that it becomes standardised? submitted by /u/BlueSuperSaiyan79 [link] [comments]

Which is more conductive, frozen or liquid H2O? Can anyone clarify? Posted: 17 Feb 2017 04:45 PM PST Hi all, I have read some mixed responses on the conductivity of liquid water vs. ice. I am aware that the ions themselves conduct, not the water, but a couple of websites (and a previous Ask Science) contradict each other by suggesting liquid water conducts electricity better than ice, and vice versa: https://van.physics.illinois.edu/qa/listing.php?id=16435 vs. https://www.reddit.com/r/askscience/comments/1gxqlq/does_ice_conduct_electricity_as_well_as_water_if/caoyxb9/ Which is correct? I have also heard from a coworker who is an electrician that the conductivity is actually the same. Can someone please clarify? submitted by /u/Siludin [link] [comments]

The 4 fundamental forces of nature are well known, but how far can they be condensed? Posted: 17 Feb 2017 03:15 AM PST Everybody was taught about the 4 fundamental forces of nature ( weak interaction, strong interaction, gravity, and electromagnetism), but lately the weak interaction and electromagnetism can be unified as the Electroweak Force, while the Strong interaction sometimes gets split into 'residual' vs 'fundamental'. Also, quintessence is mentioned in several theories. submitted by /u/polio18 [link] [comments]

Is the moon slowing down? Posted: 17 Feb 2017 04:08 AM PST Nothing in this life is free, and neither I assume is the energy that the Moon imparts on the Earth in terms of tides. Therefore I assume the Moon faces resistance in its orbit around the Earth, and so must be slowing down, and getting closer to the Earth. Am I right? submitted by /u/George5562 [link] [comments]

Ask us anything! Posted: 17 Feb 2017 04:16 AM PST Hi Reddit! I'm NOAA Fisheries scientist Jamison Smith. I am the NOAA Fisheries National Entanglement Response Program Coordinator and I oversee NOAA's whale entanglement response teams. And I'm Ed Lyman, I serve as the large whale entanglement response coordinator for Hawaiian Islands Humpback Whale National Marine Sanctuary. Whales are becoming entangled in fishing gear and marine debris at an increasing rate and scientists are unsure why. Scar studies in U.S. waters show that 83 percent of all right whales and 70 percent of whales overall have been entangled in fishing gear or other marine debris at some point in their lives. Fortunately, the efforts of whale entanglement response teams are paying off. There are endangered North Atlantic right whales alive and reproducing today because of successful disentanglement efforts of NOAA Fisheries and our partners. Whale entanglement response teams must be available at a moment's notice and they deal with a variety of cetacean species, from the largest to the smallest, in a range of different ocean and weather conditions. These teams are highly skilled and use specialized equipment to cut whales free from tangled lines, buoys, and other debris. They can also administer on-site medical care to treat wounds and promote continued recovery. If you're interested in whales and the people who spend their lives saving them, this is your chance to learn more. We're here from 1:00 to 3:00 p.m. ET today to answer your questions.

Posted: 16 Feb 2017 07:19 PM PST It seems to me nothing would have the mass to form a galaxy without being a black hole.

I don't understand band theory. How come the density of states at the Fermi level determines if a material is a conductor or not? Posted: 16 Feb 2017 07:10 PM PST Every intro level textbook has some version of this picture: https://en.wikipedia.org/wiki/Electronic_band_structure#/media/File:Band_filling_diagram.svg . Then, there is always some handwaving about how the density of states determines if it is possible to excite electrons, and that whether or not electrons can be excited determines whether or not the material conducts electricity. I'm stuck on the "possible to excite electrons" implies "material is a conductor" step. I think the reason is that people usually talk about the classical theory of conductivity, i.e. the Drude model, and I can't imagine what the quantum version of the theory of conductivity would look like. How does the wavefunction electron in a metal look compared to one in an insulator? Also, what about indium tin oxide? How does that work? submitted by /u/horsedickery [link] [comments]

Why do we call the final form of an insect an imago? Posted: 16 Feb 2017 05:14 PM PST I am familiar with the meanings of the word in Latin, and I can generate some plausible answers. But better than an informed guess would be if somebody can tell us what actually was the thinking that did lead people to assign that particular term to the entomological concept. submitted by /u/Robot4Ronnie [link] [comments]

Are black holes all thought to be homogeneous internally, or is it possible for a large enough collection of massive objects in a small enough space sufficient to create an event horizon? Posted: 16 Feb 2017 10:48 AM PST I have a layman's understanding of physics and astronomical phenomena, so please forgive me if this question is absurd. However, it occurred to me that it might be possible for enough material- such as suns and so forth- to be in such close proximity that their collective gravitation creates a black hole to outside observers, even though it isn't really a single blob of matter- but for all intents and purposes it would still appear that way to outside observers. I guess my question is- is this possible, or is it something that would be rendered impossible by the requirements for how dense a mass must be to create an even horizon? Thanks! submitted by /u/corey_m_snow [link] [comments]

What are the differences between the modern Windows filesystem and the modern Unix filesystem? Where did those differences come from? Posted: 16 Feb 2017 11:28 AM PST In a computer science course I'm in, we covered that Unix file systems use a logical filesystem on top of the physical file system. I understand a bit, but it can get a bit confusing. As I understand it, the logical file system sometimes allows for smaller file sizes (via File Holes) and allows for easier mounting of seperate drives and devices, as they all become effectively just a part of the overall filesystem tree. I think I'd just understand this stuff a lot better if someone here explained it to me though, so thanks for any help. :) submitted by /u/Night_Thastus [link] [comments]

Has surface of the Earth always been covered to 71% by water? Posted: 16 Feb 2017 05:51 PM PST So I saw that news about a newfound continent, and was wondering, has dry land on surface always been only 29% of its surface? I'm not sure even if there is a way to find that out. For example, the ancient continent Pangaea. It was consisted out of all continents that exist today, and thus how do we know that percent here and there hasn't been lost (or gained) since then through all the tectonic movement? And no, I don't consider that super ancient period of Earth in which water existed only in form of steam. So, lets start the countdown since planet "cooled a bit". I won't apologize for my English, it's not my native language. submitted by /u/Kaladrion [link] [comments]

Would jumping in this situation help? Posted: 16 Feb 2017 05:53 PM PST Let's say you're standing on a platform at the side of a tall building (like a window washer) and let's say you fall. Before you reach the ground you kick off the platform that you're standing on going vertically will this reduce the impact upon hitting the ground. May be a stupid question but i'm curious. Thanks in advance submitted by /u/Im-Kazuma-Desu [link] [comments]

Does colour affect emissivity of an object? Posted: 16 Feb 2017 12:45 PM PST Not sure if I'm using emissivity correctly, but I guess my question is If I have two similar objects A being coloured white and B coloured black would the colour of the object affect how well it absorbs radiation? I'm not speaking about light based like the sun, but purely just heat submitted by /u/d0t1q [link] [comments]

Are stars getting smaller? Posted: 16 Feb 2017 01:45 PM PST Correct me if I am wrong, but stars are born in a nebula, which are the remnants of a supernova? If multiple stars are born in nebulae like in the pillars of creation, then surely an individual star will never be as massive as its parent star? submitted by /u/fililili [link] [comments]

What are serotonergic psychedelics such as LSD and DMT doing to the brain? Posted: 16 Feb 2017 09:18 AM PST Serotonergic psychedelics bind to serotonin receptors (among others), eliciting their effects primarily through 5HT2A agonism. My question is, what is happening beyond these compounds binding to receptors? How do these receptors normally influence the behavior of individual neurons when bound to by serotonin, and how does this activity differ when LSD or DMT are binding to these receptors? What does LSD do that serotonin doesn't? How are these compounds able to induce their subjective effects? submitted by /u/EyeOfSol [link] [comments]

How do stars get 'eaten' by black holes? Why don't they just orbit? Posted: 16 Feb 2017 12:36 PM PST I've seen lots of images like this one: http://imgur.com/a/AZ1Gp But, why would the star spiral inward? Why wouldn't it just orbit or maybe create a ring around the black hole? It seems like the pieces getting 'eaten' are losing kinetic energy somehow, but I don't see why that's happening. submitted by /u/saad85 [link] [comments]

How can scientists calculate Lagrange points between two objects when there are more than two gravitational forces acting on the point?

Why does yellow exist on the light spectrum but not pink? Posted: 16 Feb 2017 07:15 AM PST Just read an article about how pink does not exist on the light spectrum, but our brain creates it to signify that it's "not green" Here is the link: Pink does not exist. In essence it's saying that we only have red, green, and blue cones in our eyes, and when your red and blue cones fire but not green, your brain in a way "creates" purple. However, we also can't "detect" yellow. It appears when our red and green cones fire. Yet for some reason we call yellow "real" because it appears on the light spectrum. However, that doesn't make any sense to me, all that means to me is that the wave length between blue and green fires both my blue and green cones. For all I know the "yellow" section is just a mix of green and blue light. In other words, why does yellow exist if we can't even detect it, but pink doesn't just because it's not on the spectrum? Seems like they are doing the same thing to me. submitted by /u/Atibana [link] [comments]

Would Bill Nye's warming demo work? Posted: 16 Feb 2017 11:38 AM PST Bill Nye has a great short video talking about the concept of global warming. At 50s in, or so, he starts a demonstration of global warming with two jars. The odd thing, to me, is that glass absorbs most IR radiation; the additional absorption of CO2, I would think, would be minimal. But I am not sure. Has anyone tried this? I'm curious if it would work as well as they present, or if (as I would suspect) the additional CO2 would absorb a relatively small amount of heat compared to the glass. submitted by /u/formative_informer [link] [comments]

Why do falling rain and blowing snow tend to create channels about 5-10cm across? Posted: 16 Feb 2017 02:42 PM PST When I see rain fall it tends to be clustered into channels about 5-10cm across. When I see snow blowing it tends to do the same, and I can see that the channels are in the same direction as the as the wind. My best guess is that the precipitation creates a drag on the moving air and it moves into the higher velocity channels that push the precipitation into the slower channels. The high velocity channels would be like the streams of water down a window, and the channels of precipitation would be the spaces between the streams. Is this related to the sand ripples that are created orthogonal to the motion of the water? Would snow more precisely be called 'precipitate' rather than 'precipitation'? submitted by /u/subsidiarity [link] [comments]

Is there a maximum temperature a microwave oven can heat up a piece of food? Posted: 15 Feb 2017 06:51 PM PST More specifically, will it heat up 1 pound of chicken and one pound of pie to the same (max) temperature, or will one inherently get hotter than the other? What determines the maximum temperature, and what item do we think could get the absolute hottest due only to a microwave oven? Thanks! submitted by /u/MrHanSolo [link] [comments]

how can oceanic dissolved oxygen decline if an increase in gas temperature usually means increase in dissolved oxygen? Posted: 15 Feb 2017 03:51 PM PST submitted by /u/masahawk [link] [comments]

If a conductive metal in wiring for a home is in liquid/melted form, will it still conduct electricity as well or at all? Posted: 15 Feb 2017 11:28 PM PST If the wiring in a house, copper for example was melted but still held in a linear form within the rubber insulation, would it still conduct electricity as well? submitted by /u/RavioliMaster [link] [comments]

When photons blueshift while they approach a black hole, does this mean they add more energy to the black hole than what their energy level was before being blueshifted? Posted: 15 Feb 2017 01:31 PM PST submitted by /u/empire314 [link] [comments]

In regards to Bernoulli's principle, why do the behaviors of velocity/pressure become opposite when a fluid is traveling through an orifice at supersonic speed? Posted: 15 Feb 2017 02:56 PM PST submitted by /u/cmnd_ctrI [link] [comments]

Why do some people who contract infections show no symptoms? Posted: 15 Feb 2017 05:28 PM PST How are some (most) cases of influenza, etc asymptomatic? Does this mean the body has fought and removed the virus without giving symptoms? submitted by /u/vsbobclear [link] [comments]

How far does electricity travel in water? Posted: 15 Feb 2017 04:43 PM PST No clue why this just popped into my head but i was wondering how far any given current can travel in water. or how you might be able to calculate. i'm sure the salinity also has something to do with it too! submitted by /u/ackley14 [link] [comments]

How much snow would cover the world if an ice age occurred? Posted: 15 Feb 2017 08:19 AM PST How much snow would cover the world if the entire world went in to a severe ice age? How much of the evaporated water that is already in the air would cover the ground? After so long of it being freezing outside all the moisture would forever be frozen and no more water could evaporate? submitted by /u/UniqueUsername789 [link] [comments]

True versus false vacuums or ground states are often explained with a certain graph. What do the axes of this graph represent in terms of QFT, if anything? Posted: 15 Feb 2017 11:45 PM PST The kind of graph in question looks like this: False Vacuum Graph Often a metaphor of placing a ball somewhere on the graph and letting it roll is used to explain true and false vacuum, metastability, and other such things. This is a great way to make things intuitive, but I'm having trouble understanding what it actually means for the ball to move on the graph. The y-axis seems to be some measure of energy, but what's the x-axis? (or what does it 'represent' if the value isn't necessarily a scalar)? submitted by /u/AlphaModder [link] [comments]

What number would our number system have to be based on for PI to be equal to 3.2? Posted: 15 Feb 2017 09:14 PM PST submitted by /u/sgasgdsgbdsg [link] [comments]

There is a picture of a piece of wood under an electron microscope on the front page. If the microscope was 5x more powerful, would the picture still look the same? At what point do you reach an end to magnification where you cant see any smaller details? Posted: 15 Feb 2017 06:26 PM PST submitted by /u/EveSaintRaven [link] [comments]

Modern CPU's have > 1 Billion transistors... are all of them actually used? Posted: 15 Feb 2017 11:51 AM PST Just because there exists a transistor on the chip, that doesn't necessarily mean the chip itself is designed to use the transistor, right? If this is the case, we should see either more complex CPU's and/or more efficient CPU's as niche solutions are given hardware space, right? submitted by /u/GregoryPanic [link] [comments]

How do I see an elliptic curve is topologically equivalent to a torus without using elliptic functions? Posted: 15 Feb 2017 09:00 AM PST submitted by /u/swapwaspspaw [link] [comments]

How can maser emission be unpolarized? Posted: 15 Feb 2017 08:44 AM PST I was reading that: However, unlike Galactic sources such as W3(OH), the emission is unpolarized and the 1667 MHz line is stronger than the 1665 MHz line. but how is this possible? Does not the 1665 MHz line and 1667 MHz line correspond to a particular transition and dipole moment? Won't emitted photons naturally have a polarization? Furthermore, they state: The characteristics of the λ18 cm OH mega-maser emission differ from those of Galactic maser sources, such as the main line intensity ratio (T1667MHz/T1665 MHz > 1), large linewidth (>100 km s−1), and unpolarized emission. But why is unpolarized emission expected from extragalactic masers (arising near AGN) and not galactic ones (arising in circumstellar and interstellar environments)? submitted by /u/CallMeDoc24 [link] [comments]

Can Real numbers be partitioned into two dense, uncountable partitions? Posted: 15 Feb 2017 09:24 AM PST I have just started taking a Real Analysis course and the prof. introduced the concept of dense sets. And every example given in the class split R into two dense partitions of different sizes. So I was wondering if breaking R into two equal partitions violates some fundamental result? submitted by /u/MutedBanshee [link] [comments]

Why would solving the ABC conjecture be of importance to us? Posted: 15 Feb 2017 05:58 AM PST Hi all I am most definitely not a certified mathematician but I really enjoy reading about math and number theory (perhaps in another life I would have liked to have been one). Anyhow, why would solving the ABC conjecture be of importance to us? And also why is the proof given by Shinichi Mochizuki so difficult to peer review and confirm? Is it not possible that the math gets so abstract and convoluted after ten's of pages with proofs building on proofs made in the same text, that close to anything can be solved by using enough back and forth math (my layman's proposal here)? Or is the incredibly complicated proof to this relatively simple looking conjecture (from a layman's perspective) a whole new level of genius? submitted by /u/georgelappies [link] [comments]

What differentiates the overlap regions between Gamma & X-Rays? Posted: 15 Feb 2017 07:42 AM PST On the EM spectrum there is an overlap region between Gamma & X-Rays, how do we differentiate the two? What are different about them? submitted by /u/Theroberto9009 [link] [comments]
