How do the quantum numbers for the electrons in orbits arise from the Schrodinger's equation? Posted: 02 Apr 2017 06:26 AM PDT Side question: do these numbers relate directly to the orbital's shape?

Where is the two-dimensional space? Posted: 02 Apr 2017 02:35 AM PDT Apparently there are more dimensions in this universe, but we are not able to see them because we live in a 3D world... However, shouldn't we be able to observe worlds with fewer dimensions? The novel Flatland for example describes such a two-dimensional world, occupied by geometric figures. There is also an episode of Star Trek:TNG, where the USS Enterprise encounters two-dimensional lifeforms... So, where are these two-dimensional worlds and how could we detect them? submitted by /u/Memeito [link] [comments]

I used Stuner to illustrate my ideas. So I thought of 3 different scenarios: Inwards : http://prnt.sc/erfp96 Perpendicular : http://prnt.sc/erfpc7 Outwards : http://prnt.sc/erfpf6 What I want to know, in a nutshell, it's how these 3 different scenarios can change the aerodynamics of a racing car. submitted by /u/MTFKJNS [link] [comments]

How do scientists calculate the age of distance planets/stars/galaxies? Posted: 01 Apr 2017 05:05 PM PDT From what I've learned from my Geology 101, we aren't even sure exactly how old the Earth and Moon are even though we have access to their rocks (brought back from the Moon in various mission in the 60s and 70s).

Why Do Protons and Neutrons Have Slightly Different Masses? Posted: 01 Apr 2017 03:26 AM PDT As I understand, the only difference between the two is that a proton consists of two up quarks and a down quark, and a neutron consists of two down quarks and an up quark. I know their masses are almost exactly the same, but why aren't they EXACTLY exactly the same? submitted by /u/Kurausukun [link] [comments]

Are there any species in which the females compete with one another over males for sex? Posted: 31 Mar 2017 05:32 PM PDT It seems like a lot of species in the animal kingdom have the males compete (fight, show off, etc.) with one another for "breeding rights" with the females. Is there any species that do the opposite of this? submitted by /u/WafflesAndCuddles [link] [comments]

If I roll two dice, what is the average number of rolls I need to perform to get all 36 combinations? Posted: 31 Mar 2017 04:47 PM PDT I just did a few thousand simulations in matlab and got an average of about 150.2 attempts, or about 4.172 times the number of combinations. I was interested if there's an elegant formula to arrive at this number rather than brute-forcing it. submitted by /u/BaryonicM [link] [comments]

How do I derive a form of the Navier-Stokes Law which realistically reflects the vorticity surrounding complexly spinose Odontopleurid trilobites in conditions of incompressible steady flow? Posted: 01 Apr 2017 04:10 AM PDT The recurring emergence of extreme spinosity in certain Trilobite lineages in the Paleozoic has been interpreted as adaptive specialisation to a planktonic lifestyle. However, Stokes Law merely demonstrates that a sphere of a given diameter may show suspension behavior in conditions of incompressible steady flow, for a given vorticity of ω = Ñ ₓ u. But spinescence directly affects vorticity in a chaotic fashion, and the resolution of Stokes law only covers the trivial scenario where y = -½ur² [1-3/2 (R/Ö r²+z²) + ½ (R/Ör²+z²)³]· … such a simplistic approximation won't do….* I'm supposed to believe that the behavior of this guy in freefall in the water column is the same as that of a sphere or equal volume … try that with a small pebble vs a dandelion seed and see where that gets you… This is the same approach taken by theoretical physicists who approximate the geometry of a cow by postulating it is spherical. Which is entirely inappropriate to my problem (not to mention rude to the cows, which are noble creatures of great chastity and virtue who deserve better). How do I solve Stokes law in such a manner as to take into account the actual shape of presumably planktonic complexly spinose trilobites such as Radiaspis radiata in a realistic fashion, "spherical cows" be-damned? Otherwise I'll be stuck trying to figure out what to feed the spiny buggers if Stokes Law cannot account for their floating around with the rest of the plankton. It's a thorny problem. submitted by /u/Gargatua13013 [link] [comments]

I'm using a markov chain analysis to describe the development of a fouling community. Can anyone tell me how likely Aplidium pallidum is to replace Parasmittina jeffreysi? Posted: 31 Mar 2017 05:03 PM PDT submitted by /u/atomfullerene [link] [comments]

How distorted has the spherical cow problem made our understanding of the laws of physics, the universe and everything? Posted: 01 Apr 2017 07:42 AM PDT Spherical cows have been extensively introduced as a short cut to avoid realistic complexity in the literature of physics problem solving. Surely we have paid an unholy price for this perversion. All are welcome to contribute their experiences to this discussion of how far down the rabbit hole this cow conundrum has dragged us, and restore bovine dignity. May I propose an incremental improvement by adopting a yam standard? submitted by /u/Gargatua13013 [link] [comments]

What is the ultimate fate of rogue planets (and planets that survive their stars death remain in orbit?)? Posted: 31 Mar 2017 05:26 PM PDT What happens to planets that still exist as stars eventually stop forming and being to die out? Would they just exist forever until they eventually fall into a black hole? submitted by /u/daman345 [link] [comments]

Kidney paradoxical autonomic innervation? Posted: 31 Mar 2017 08:52 PM PDT The autonomic innervation of the bladder and internal urethral sphincter(IUS) confuses me. Under parasympathetic stimulation the detrusor muscle contracts and the IUS relaxes, right? The opposite is true for sympathetic responses: detrusor relaxes and IUS constricts. So why do some void their bladders when they are scared, under sympathetic control? submitted by /u/jedwards55 [link] [comments]

How did we know which Galilean moons was which when we first imaged Jupiter? Posted: 31 Mar 2017 12:03 PM PDT When Galileo looked at the Jovian Moons and named and identified them how did we know which was which when we pointed telescopes and Pioneer, Voyager and other spacecraft imaged the planet and its moons? submitted by /u/Myoplasmic [link] [comments]

How would a girl be affected by having a hysterectomy at a young age? Posted: 31 Mar 2017 06:42 AM PDT How would a "castrated" human female develop? How would such a person look and behave? submitted by /u/Darklord494 [link] [comments]

Have GMO engineers ever tried to modify organisms (fungi, bacteria, etc) that are naturally symbiotic to food crops? Posted: 31 Mar 2017 07:34 AM PDT Just some background: ~80% of terrestrial plant species have a symbiotic relationship with mycorrhizal fungi. In naturally occurring mycorrhizal-plant symbiosis, plants can better grow in nutrient deficient soil, better resist pest, better resist droughts, and even repopulate barren soil. If naturally occurring mycorrhizal nets can do all that, I can't imagine what a genetically modified species might be able to do for our food crops. Has ever been an attempt to modify mycorrhizal fungal species to better aid food crop growth, or to modify other fungi/bacteria to either occupy niches (which might otherwise be occupied by a pathogenic species) or even actively defend the plants against pathogens and pests? submitted by /u/Gonzo_Rick [link] [comments]

Can I break causality by exploiting the reduced speed light travels in a medium? Posted: 31 Mar 2017 03:51 PM PDT Lets say through a certain medium, light travels at 99.9% c. Now lets say I made a spaceship that can reach 99.99% c. Am I technically moving faster than light, and therefore breaking causality? submitted by /u/supereuphonium [link] [comments]

How does Egalitarian Paxos solve this Failure case? Posted: 31 Mar 2017 12:00 PM PDT My friend & brilliant colleague Ari Pfolol, during a slightly heated discussion between five patrons in the bar, unrelated to us, turned to me and asked: "Consider, for simplicity, a replica group of five nodes running EPaxos. The fast-path quorum size for five replicas is 3×(F+⌊F+12⌋) (sic), the same size as a simple majority. Let us name the replicas A, B, C, D, E. Consider the situation which occurs when a client successfully completes one operation (with side-effects, i.e. writes), then issues a second in sequence, and then some failure occurs before the second operation completes and the recovery protocol incorrectly orders the second operation before the first. Suppose the first operation uses A as leader with C and D making up the other fast-path quorum members, while the second operation uses B as leader with D and E as quorum members. Furthermore, let's say that: A fast-path commits operation 1, responding success to the client but crashing right before it sends "commit" messages to C and D then, B sends pre-accepts to D and E (without operation 1 in the deps because B doesn't know about operation 1 yet), and also crashes The system has suffered two failures but must recover and continue operation, since five replicas can tolerate two failures in EPaxos per the paper's claim. However, the remaining replicas look like this (with the 'indices' representing which operation the replica has pre-accepted in its log): X X / \ / \ C1 D1 E2 At this point, each replica knows about only one of the two operations but not whether it is committed, and both operations conflict with each other (see the tech report §6.2 #6 for exactly what "conflicts" means). But when C, D, or E initiates recovery for operations 1 and 2, how does it know which operation, if any, was fast-path committed and in which order, given that it only knows about exactly one of the ongoing operations?" I put it to you, /r/askscience, what the hell is he talking about? On the off-chance he's not drunk, Is There Really More Consensus in Egalitarian Parliaments? Should we leave the bar? submitted by /u/mfukar [link] [comments]

If phone lines (but not necessarily modems) transmitted perfectly, how fast could dial-up modems transfer data? Posted: 31 Mar 2017 10:05 AM PDT Since the transfer rate of the modem depends on how fast it can modulate (and demodulate) bits into an interrupted tone, phone line noise would cause high speed modems to lose data in transmission, but if a phone line were to be perfect (i.e no noise and all transmissions came through the other end of the line exactly as they were input), how fast could we potentially build a modem? submitted by /u/ralfsmouse [link] [comments]

How do "regular" elements such as Zinc can become something like Zinc-62? Posted: 31 Mar 2017 11:14 AM PDT Does it occur naturally or does it need human intervention to do so? Say for instance, in a laboratory, something is labeled simply as Zinc, how can we determine what type of zinc it is? Thanks in advance! submitted by /u/papercut03 [link] [comments]

How do cells combat listeria? Posted: 31 Mar 2017 09:35 AM PDT If antibodies normally act outside the cell, and listeria acts within the cell (it gets transported between cells via phagocytosis), how do cells/the human body normally combat listeria, e.g. what antibiotic factors does the cell express (which it must, because listeria normally isn't fatal unless it infects those who are immunologically compromised, such as the old, young, or pregnant)? submitted by /u/Setsikas [link] [comments]

Are there animals with more than one fovea per eye? Posted: 31 Mar 2017 06:46 AM PDT I just learned on wikipedia that cuttlefish has two foveas per eye. And it moves it lens to focus, instead of changing its shape. Incidental questions: Does all animals have one lens per fovea? Are there other animals that moves it lens to focus? Please tell me more about unusual (not human like) eye biology. submitted by /u/jogaforaffd [link] [comments]

AskScience AMA Series: I am Greg Matloff, and I work on the science of interstellar travel. Ask Me Anything! Posted: 31 Mar 2017 05:01 AM PDT Greg Matloff, Ph.D., is a recognized expert on interstellar travel. He lives with his wife, artist C Bangs, in Brooklyn, New York. Greg teaches physics and astronomy at the City University of New York, has consulted for NASA, is the author or co-author of 12 books and more that 130 scientific papers and serves as an advisor to Yuri Milner's Project Breakthrough Starshot. Although he has contributed to studies of extra-solar planet detection, Earth atmosphere chemistry, Earth defense from asteroid impacts and the search for extraterrestrial intelligence, his main research interest is the solar photon sail. Greg feels that the human future and that of our planet's biosphere will be shaped by our ability to utilize solar system resources for terrestrial benefit. He has recently contributed to the scientific investigation of the possibility that the universe is conscious. See google scholar for his publications, or at www.gregmatloff.com and www.conscious-stars.com. Our guest will be joining us starting at 12 PM ET (16 UT).

How do incubating eggs survive without an oxygen supply inside the egg? Posted: 30 Mar 2017 08:28 PM PDT Saw the gif of a baby snek emerging from an egg and taking a big first breath, and I wondered how it was breathing before it emerged? submitted by /u/ISawTwoSquirrels [link] [comments]

[Mathematics] What number refers to the number of possible orderings of natural numbers? Posted: 30 Mar 2017 09:21 PM PDT The number of unique orderings of a set of length n is n! and as such it seems logical to me that the number of unique orderings of the natural numbers is Aleph null factorial, but what does it mean to take the factorial of an infinitely large number as infinity minus one is still infinity(i think). I was also thinking about the Continuum hypothesis which says that the cardinality of the set of real numbers is 2 raised to the Aleph null. x! grows faster than 2x so would that make the number of unique orderings of the natural numbers to be larger than the set of real numbers(assuming that we are able to take the factorial of Aleph null)? Apologies if my question makes assumptions which are incorrect, but thanks for reading! submitted by /u/AloysiusSnuffy [link] [comments]

What factors determine the optimal body temperature of an endothermic species? Posted: 30 Mar 2017 07:53 PM PDT Reading that the "low" body temperature (94 - 97 F) of opossums made them less vulnerable to rabies got me thinking about the "normal" body temperatures of other mammals. After some Googling I could find little obvious pattern in the optimal temperature of different species, other than monotremes having lower temperatures than marsupials, which in turn have lower temperatures than placentals. But what other factors go into determining the "healthy" temperature of an endothermic species? submitted by /u/GargoylesGarglingOil [link] [comments]

If two object with different thermal energy values were sitting in a pure vacuum without physical contact would they still eventually exchange heat? If so, how? Posted: 30 Mar 2017 10:54 PM PDT To my understanding all thermal exchange needs an interaction of molecules to take place, higher energy values 'gravitate' then mix in with lower energy states. If there is no 'physical' or atomic interaction to take place, would the atom excitation release from both objects and then eventually interact with each other until equilibrium was reached? submitted by /u/cephsdiablo [link] [comments]

When the Chicago River's flow was reversed in 1900, what was the public health impact to the American South along the Mississippi River? Posted: 30 Mar 2017 05:14 PM PDT The flow was reversed because people in Chicago were getting sick due to the presence of human waste and other contaminants in the river. Reversing the flow reduced the spread of disease because it no longer gathered in Lake Michigan. However, that stuff didn't disappear. How did the reversal impact public health along the Mississippi River, the new destination for Chicago's waste and sewage? submitted by /u/superbadninja [link] [comments]

How was the rotational speed of the Fizeau–Foucault apparatus measured accurately enough to calculate the speed of light with only a 5% error in the 1840s? Posted: 30 Mar 2017 03:56 PM PDT I love the story of this discovery and the problem--solving aspect of it, but it seems like every description I've seen omits how in the world Fizeau was able to determine the speed of the spinning toothed wheel close enough to be remotely useful without any sort of digital timing device. Am I the only one missing this piece of the puzzle? Did he just estimate over and over and take an average that happened to be in the ballpark?
