Microstates in statistical mechanics and Pauli's exclusion principle - how do you count "the number of possible positions"? Posted: 01 Oct 2017 07:07 AM PDT Space is continuous, right? Microstates How can you ever arrive at a finite number of "microscopic arrangements of particles" when counting W in Boltzmann's entropy equation? S = k_B log W It seems to me that there are infinite ways to arrange 1000 particles in a box while keeping the same volume, pressure, etc. (I understand that introducing quantum mechanics changes this question a bit, but I'm also interested in the classical answer, since Boltzmann and his contemporaries only knew classical physics...) Pauli Exclusion Principle The same question goes to filling up phase space with electrons according to Pauli's exclusion principle. You can't have two electrons in the same quantum state, so if you stick to one position you have to stack them in a tower of increasing momentum. But what does "one position" even mean? If you move 10-700m to the left, does that count as a new position where you can start a new tower of momenta? Surely not. How much space does one "quantum state slot" take up? If they take up space, does this mean electrons are fat? submitted by /u/Schpwuette [link] [comments]

Are there thermal neutrinos? Posted: 30 Sep 2017 09:36 PM PDT So thermal neutrons are neutrons that come to thermal equilibrium with their surroundings. Do neutrinos do the same thing? Once created in stars and supernovae, would neutrinos "cool" down overtime? Plots like this indicate that "cooler" lower energy neutrinos should have smaller nuclear cross section. I usually imagine neutrinos as high energy particles zipping around. Could instead very low energy neutrinos be floating around not interacting with anything? submitted by /u/siliconlife [link] [comments]

When you shine light at a mirror, does the amount of light in the room change? Posted: 30 Sep 2017 09:20 PM PDT This seems like a dumb question. But what if you looked at the light and it's reflection in the same visual frame? Then would the amount of light be double? submitted by /u/lbon6201 [link] [comments]

Is there any research on the percentage of depressive outpatients that complain of loss of cognitive function(and of which type) even after their illness remission? Posted: 30 Sep 2017 04:52 PM PDT I am asking specifically for outpatients since it seems there is a difference of cognitive loss between 'inpatient' and 'outpatient' depression and even different loss of grey matter in several parts of the brain. submitted by /u/Periplokos [link] [comments]

If we can use vaccines to "train" the immune system to fight diseases, is it possible to make an "anti-vaccine" that would condition it to NOT fight allergens?

How does the brain map give sensation to a phantom limb? Posted: 30 Sep 2017 02:55 PM PDT From what I've read there is a brain map that associates sensation of touch of each body part to a region of the brain. The hand and feet map to different brain regions for example. But do we have any idea of how each of those regions give rise to a conscious feeling of being touched in the hand or feet respectively. When we are touched in the hand or foot a brain imaging would show different regions of the brain activating. But what is giving rise to the conscious awareness of "where" on the body is being touched? I mean like it seems that like if someone was born with an extra finger that they would have a sensation of knowing when that finger is touched. Yet everyone else without a sixth finger would never have that sensation of a sixth finger touched no matter what implanted electrodes were stimulating our brain. What is different in their brain that gives rise to conscious spatial awareness of a sixth finger being touched? I don't know how to articulate this question precisely. I hope someone understands what I'm getting at. submitted by /u/whyislemonbad [link] [comments]

Why did the STS do roll reversals instead of descending from a higher longitude? Posted: 30 Sep 2017 03:44 PM PDT After watching a video on how to land the space shuttle I'm curious as to why did the STS do roll-reversals instead of beginning descent from a higher longitude (I'm not sure this is the correct term so I did a picture): link Would the azimuth error be too high and require roll reversals anyway? submitted by /u/RBozydar [link] [comments]

What is the difference between these equations involving Strangeness Conservation that makes one permissible and one not? Posted: 30 Sep 2017 08:51 AM PDT Why is Λ0 -> p + π- permissible, but K- + p -> n + π0 not? uds -> uud + du and su + uud -> udd + uu Both involve a change of quark flavour - the s quark of the Λ0 and K- both becoming down quarks - implying the Weak Interaction and hence Strangeness not necessarily being conserved. So what is different between the two interactions that means the second is a no-no? The two interactions have been pulled from different sources. The first is from Hyperphysics and the second is from a CGP textbook which claims it is not allowed. Admittedly the textbook does not even approach the idea that Strangeness is not always conserved... EDIT: got the sources mixed up. submitted by /u/ikilledvestein [link] [comments]

Is there a way or has there ever been a case where protons are removed from the nucleus of an atom? Posted: 29 Sep 2017 06:28 PM PDT I don't know much about atoms and science-y things, but I've been wondering if there ever has been an instance where protons were removed from the nucleus of an atom, or if there's a theoretical way to do so.

How hazardous and toxic will it be if a nuclear warhead containing plutonium would disintegrate at reentry without detonation? Posted: 30 Sep 2017 02:09 AM PDT With all the tensions between US-NK and the later's reentry test failures, I'm curious if even a failed nuclear warhead can have grave consequences on its target. Plutonium is one of the most toxic elements to life that we know of if ingested somehow into our bodies. Lets presume that the reentry vehicle of the North Koreans is similar to the american W87. The materials used in the design of the cone are state secret (Most likely something with good refractory properties, like carbon etc), but lets assume that the entire vehicle fails/cracks open exposing the peanut core at high altitude and allows it to burn into the atmosphere. Are there any safety mechanisms for this situation, at least used by the nations that have experience with nuclear weapons? What is the trigger of such a weapon, and could such a fail activate it and detonate it into the high atmosphere? submitted by /u/path_ologic [link] [comments]

Constant acceleration/deceleration as artificial gravity? Posted: 30 Sep 2017 05:27 AM PDT One of the main challenges of a crewed mission to Mars is the prolonged period of microgravity and its negative health effects. Setting aside the limitations of fuel, would it be possible to launch a ship that had a constant one-g acceleration until halfway to Mars, and then a constant one-g deceleration for the rest of the trip? I know orbital mechanics are tricky, so I'm not sure that it would work, but if we somehow had an engine and fuel source that could do it, the crew would effectively have artificial gravity for almost the entire trip. submitted by /u/skip6235 [link] [comments]

How does algae reproduce in mountain streams without being "flushed out"? Posted: 29 Sep 2017 01:25 PM PDT I've been taught that algae reproduces either asexually or through spores.

Why is the C.M.B. visible in every direction? Posted: 28 Sep 2017 05:17 PM PDT If it is the case that the big bang was a local event; how is it that the cosmic microwave background is visible from every spacial angle? If there was superluminal expansion, surely only one direction should have the remnants. If the photons escaped the plasma during expansion, surely there was nothing for them to scatter off of -- back towards us -- and we shouldn't see anything. Is it topological? Something like a 4-D stereographic projection where the projection point is the big bang such that all 3-D spacial paths trace a meridian back into the past?

Why electric waves and magnetic waves are at right angles? Posted: 28 Sep 2017 06:04 PM PDT Hi I'm looking into electromagnetic waves and have found lots of information about how a positive electrical charge creates a magnetic field and vice versa.. But I haven't yet found an explanation as to why they are created at a right angle? Logic would tell me that from an event, the result would be created in all directions, so why at a right angle? And also, with these events not actually being flat in any sense, what is the right angle even relative to? If anyone has a link to a video or something that could explain this it'd be much appreciated. If the answers become too mathematical, I won't be able to follow.

How is the effect of drugs on fetuses tested when taken by the mother? Posted: 28 Sep 2017 01:26 PM PDT So I was listening to a podcast today that was discussing Thalidomide back in the 60s. One consequence they brought up of all of the birth defects in children whose mothers had taken thalidomide for morning sickness was this led to clinical trials excluding all women until the 90s, and not until 2016 was it mandated that women be included in all phases of testing, which seems absolutely crazy to me. So that got me wondering, how do doctors determine the effects different medicines will have on fetuses. I can't imagine anyone would risk their child's life to participate in a study. Do they just have to use anecdotal evidence? Are pregnant women simply advised to not take anything for fear of damaging the fetus. And what about drugs specifically intended for pregnant women? submitted by /u/Jts124 [link] [comments]

When you think about a body part (without moving it), are you causing any physiological changes in that body part? Posted: 28 Sep 2017 07:00 AM PDT For example sending any electrical signals, or strengthening any nerve pathways? Or are you just bringing to mind the signals it's already giving you that you just weren't focused on before (like if it's hot or cold or if it's in pain)? I was thinking about this originally in the context of yoga but am now just curious about how thinking about a body part works. Often in yoga classes instructors will tell you to "focus on" or "bring awareness to" a certain body part, usually at the beginning or end of a class while you are doing a bit of meditation.

Does p-orbital transition to s-orbital by oscillating probability density from lobe to lobe and settling down as a sphere, tracing out a sine wave of electrical disturbance as a photon? Posted: 28 Sep 2017 11:13 AM PDT Catchy title, I know, but I had to phrase it as a question to get accepted... During my physics degree, I'm sure I recall seeing an animation of a p (dumbell shaped) orbital decaying into an s (spherical) orbital by the charge distribution swaying between the two lobes of the p-orbital and eventually coming to a rest in the middle as a sphere. As the charge moves from side to side, it traces out a sine wave - the photon being emitted. a) Does anyone have any idea whether this is an accurate representation of electron transitions emitting photons (and presumably the opposite occurring when a photon strikes an s-orbital and excites the electron into a p-orbital)? My gut instinct tells me that this is pretty accurate, and fits with what I recall from quantum mechanics lectures about wave equations and so on. and b) Does anyone know where I could find a copy of this animation? Searching Google and YouTube only brings up unanimated diagrams showing an instantaneous "flip" into the other orbital shape. I'd estimate that the original clip I saw was 30s long, but may have been part of a longer video - I saw this sometime before 2009, so my recall is hazy. submitted by /u/crumpledlinensuit [link] [comments]
