| Can you explain the logical leap from gravity to holographic principle? Posted: 06 May 2017 02:04 AM PDT I am already aware of the math behind (classical) thermodynamics, special relativity and quantum mechanics. How does gravity change the picture? [link] [comments]  |
| Posted: 05 May 2017 02:27 PM PDT Hello there, Right now I'm sitting on my studies and a question popped up that neither me nor any of my colleagues was able to solve. The thing is this: I read about the pineal gland(releases melatonin which is important for the sleep cycle/circadian rythm etc.) which is directly activated via the absence of light in lower vertebrates, while higher vertebrates possess the suprachiasmatic nucleus, that is concerned with innervating the pineal gland. Is this only because of the different organization of e.g. humans/reptiles, or is there a functional difference and if so, does this affect jet leg? I found an article (http://animals.howstuffworks.com/pets/pets-suffer-jet-lag.htm) where it is stated that dogs and cats suffer less jet lag than monkeys for example, but this does not quite answer my question. Why I specially ask about reptiles is that some of them possess the so called 'third eye' and the fact that they are somewhat dependend on the sun. I hope I was able clearly state my question. If not feel free to ask, I'll do my best to clarify what I mean. [link] [comments]  |
| Does the human body have 3 of anything? Posted: 05 May 2017 02:15 PM PDT Edit: A few of you have picked up on this.. yes I'm asking because we are mirrored left to right and have 2 of some organs. [link] [comments]  |
| Posted: 05 May 2017 12:09 PM PDT Firstly, I don't mean to suggest that I don't believe the quantum interpretation. When I read articles about quantum mechanics, there is always a bit that says that a particle's position and velocity can't be measured to a certainty; there is always a random chance of finding either within a range, with probabilities determined by the wave function (as far as I can tell). For the sake of example, say we shot a particle at a given velocity, and then measure its position after a given period of time. If we determine the particle's velocity to be somewhere between 10 and 20 m/s, why interpret that as an indication of the particle's probabilistic nature, instead of assuming it's the effects of precision of the particle gun, the precision of the detector, the particle colliding with other particles on its way, etc?

| Posted: 05 May 2017 11:57 PM PDT ∫ sinc (x) , (-∞,∞) = π ∫ (sinc x)2 , (-∞,∞) = π ∫ |sinc x| , (-∞,∞) = ∫ √(sinc x)2 , (-∞,∞) = ∞ I have seen mathematical proofs for it, but I don't understand how taking square-root of a function would make its area infinite from 3.14 units. [link] [comments]  |
| Why is particle production ~constant as a function of rapidity? Posted: 05 May 2017 10:40 AM PDT Hi all, I'm currently brushing up on some HEP basics for an oral exam. One thing that I haven't been able to understand completely is why particles production is approximately constant as a function of rapidity in hadron collisions. I've tracked down an old note of Feynman's which people usually point to about this: http://authors.library.caltech.edu/3871/1/FEYprl69.pdf ... I think that I understand what he's getting at when he discusses the Fourier transformation of the contracted field, but I don't see how to move from the ~constant particle Pz distribution to a multiplicity distribution that is ~constant as a function of y. I know instinctively that this is true -- the ATLAS calorimeters are designed in a way that takes this into account, for instance. I'm just missing some conceptual link, and it'd be really awesome if someone could help me get all the way. Thanks! [link] [comments]  |

| What is the differences between a species group and a species complex in bacteria? Posted: 05 May 2017 01:48 PM PDT Examples of this are Enterobacter Cloacae complex and Streptococcus mitis group. What is the distinguishing difference between when you call a group of related species a complex or group? [link] [comments]  |
| Did the Earth have ice caps in the Mesozoic Era? Posted: 05 May 2017 07:32 AM PDT Portrayals of dinosaurs always seem to be in tropical/subtropical jungle. Was the entire earth like that or were there still areas with different climates? [link] [comments]  |
| What is the difference between a magnetic monopole and charged elementary particle? Posted: 05 May 2017 09:10 AM PDT If an electron has no internal structure but it has an electric charge, what makes it not be a magnetic monopole? [link] [comments]  |

| Why do soils become less acid away from granite tors? Posted: 05 May 2017 03:48 AM PDT Hello. I'm writing an NVC habitat report and I've noticed that my Ellenberg factors indicate quite clearly a less acid pH as I progress from the upland tor to the lowlands. This is obviously due to the presence of shade loving, ubiquitous generalists in my species record as opposed to characteristic calcifugous moorland, but I'm not sure about the process itself. What is the factor or factors that cause a slightly less acid pH away from the granite tors? Is it simply a change in geology or is it the cause of the plants themselves? I was under the impression that plants accumulate hydrogen ions which make soils slightly more acid though. [link] [comments]  |
