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? submitted by /u/thetimujin [link] [comments]

Do Reptiles have Jet Lag? 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. submitted by /u/5ong6 [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. submitted by /u/OllieSDdog [link] [comments]

How do we know it's 'quantum' uncertainty, and not uncertainty in measurements or interference from unknown factors? 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? submitted by /u/azamarahe [link] [comments]

How is the area under sinc function (sine cardinal) and sinc square function finite but the area under absolute sinc function infinite when absolute sinc (x) is just the square-root of sinc square function? 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. submitted by /u/lickmyspaghetti [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! submitted by /u/WIZRND [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. submitted by /u/TaylorH93 [link] [comments]

What impact does a tsunami have on ships at sea? Posted: 05 May 2017 06:20 AM PDT Hello r/askscience. How much would a big ocean-going vessel (say, a US navy Nimitz-class aircraft carrier) notice a tsunami in the middle of an open ocean, thousands of miles from shore? Would it be a destructive wall of water moving rapidly towards the ship, or would merely be a (un)noticable rise of the water level which a ship could pass over? Assume the tsunami in question is the result of an earthquake with a rating of 9.0+ on the richter scale similar to the 1700 Cascadia or 2004 Indonesia earthquakes, both of which generated massive, ocean-crossing waves. submitted by /u/Skogsmard [link] [comments]

What is the earliest a habitable planet could have formed? Posted: 04 May 2017 05:56 PM PDT The estimated age of the universe is 13.82 billion years, and the estimated age of the earth is 4.54 billion years. The first multicellular life according to wikipedia is 4.25 billion years ago. This could mean that the earth became 'habitable' after 290 million years, when the universe was 9.57 billion years old. If the universe was fairly homogeneous after its creation, I would assume that for a while it remained above the temperature life could have started. In addition, being before the time when planets could have formed and organized into stable orbits and conditions. Then when was the time after the creation of the universe that a planet would have been able to form and sustain life? submitted by /u/MonkeyLink07 [link] [comments]

To what extent can ℝ^n be generalized for n∉ℕ? Posted: 04 May 2017 05:24 PM PDT I know that ℝ0 is a point, ℝ1 is the number line, ℝ2 is the Cartesian plane, etc. I also know that we can generalize n-dimensional space to all positive real n to include fractals (for instance, the dimension of the Sierpinski triangle is log(3)/log(2)≈1.585). Is there any meaningful way to extend n-dimensional space to negative n? Complex n? Matrix N? I haven't heard of this being done, but I also know that once mathematicians define something, they like to generalize it far past what makes sense in terms of the original definition—back when numbers were just for counting, the concept of negative numbers seemed completely nonsensical. submitted by /u/MaidofMemes [link] [comments]

What happens to mass in particle smashing? Posted: 05 May 2017 12:53 AM PDT I've been wondering this for a while. What happens when particles are smashed together in, say, the Large Hadron Collider?

Do humans emit X-rays from blackbody radiation? Posted: 04 May 2017 02:39 PM PDT Infrared is the most well-known light emitted by humans, but what about the other frequencies of light? It seems by Wien's Law that there should be some–albeit a tiny amount–of every frequency emitted, but is this actually the case? submitted by /u/rizzarsh [link] [comments]

If you can convert kinetic energy into heat energy, how could the universe experience a heat death if supermassive objects like black holes or dwarf stars would constantly be attracting other bodies via gravity? Posted: 04 May 2017 04:31 PM PDT I don't know if that makes sense, but if a star were to eventually burn out and turn into a white dwarf or neutron star or something of that sort, its gravity would be around the same right? Wouldn't objects in their vicinity be affected by the gravity and therefore have kinetic energy constantly? submitted by /u/Skabonious [link] [comments]

Why don't we feed our livestock with livestock? Posted: 05 May 2017 06:50 AM PDT It would save a lot of resources if we fed our livestock with the same kind of animal, and given that they are the same animal, this means of feed would account for practically all of the livestock's nutrition needs, wouldn't it? Why aren't we doing this? I know that cattle, for instance, are herbivorous and obviously wouldn't eat another dead cow lightly, but couldn't they be fed livestock in a different form, like pellets, for instance? submitted by /u/Kukulqan [link] [comments]

Is there any kind of measurable difference in an object when its potential energy is increased? Posted: 04 May 2017 07:18 PM PDT For example, a ball at the bottom of ramp vs. at the top. It now has potential energy that it did not have before. Does this slightly increase the object's mass or is the only measure of potential energy the difference in height? If it is the latter, does this mean people at the exact same altitude anywhere on the planet have the same potential energy as each other? submitted by /u/AyYoDeano [link] [comments]

Conceptually, how does the speed of light relate to the permeability/permittivity of free space? Posted: 04 May 2017 06:27 PM PDT I know the equation that relates the three constants: c=(ε0*µ0)-(1/2) However, I never understood why this worked or if there was a conceptual reasoning behind it, so any explanation would be greatly appreciated. submitted by /u/Pekenten [link] [comments]

Is it possible to know how much of the total universe is occupied by the observable universe? Posted: 04 May 2017 02:23 PM PDT I feel like this is a pretty dumb question because it seems unanswerable by definition, but I've been surprised many times by science in the past. Is even a horrifically uncertain yet still better than random estimate possible? submitted by /u/Kcwidman [link] [comments]

Is it possible for a star to form exclusively from a cloud of Helium? Posted: 04 May 2017 01:26 PM PDT I know that most stars form from a cloud of gas from the remnants from a super nova, which most of it is hydrogen, but could a star come together with helium?

Why do fluorescent tubes contain mercury vapour? Posted: 04 May 2017 02:50 AM PDT I understand the the mercury electrons become excited, move up and energy level and then release a UV photon which then passes on energy to the electrons of a phosphorus coating, but why can't the electrons from the voltage supply pass on their charge directly to the electrons of a phosphorus atom inside the tube which would then emit the visible light photons, removing the need for the mercury vapour? submitted by /u/tepson7 [link] [comments]

Do objects less than 5730 years old have accurate dating measurements? Posted: 03 May 2017 07:33 PM PDT Okay so this may be a dumb question, but need an answer quick and didn't have the time to do enough research myself to answer it. So I'm having some debates with my parents (hardcore Creationists, I'm undecided at this point lol) one of my arguments for the errors in the creation story is the fact that dating techniques are pretty accurate and are no where near the claims of 7000 years like they like to say. I came across this one question though; if dating techniques are only accurate for greater than the half life of the element used, and carbon-14 has the smallest half life of 5730 years, is it hypothetically possible that all materials ever tested are less that 5730 years old (sort of close to a creationists timeline), and therefore all measurements can be listed as inaccurate? I may be completely out to lunch here and I apologize if I am. I'm not looking for other reasons as to why old-earth is a lot more plausible (there are enough that I am aware of already). Thanks for your time. submitted by /u/Silvanus11 [link] [comments]

Is it possible for nuclear fuel to accidentally reach criticality? Posted: 03 May 2017 05:21 PM PDT I'm gathering information for a story I'm writing and I want all aspects of the story to be as plausible as possible. So as the question states, whether in travel or handling accidents, if fuel rods were majorly damaged in any way and the pellets somehow spilled into a massive pile could it possibly go critical? Or is there a reactor fuel source other than PWR fuel rods that would be contained in a way that makes them more likely to go critical?

What is it about the chemical properties of metals such as Gold, Silver, and Titanium that make them hypoallergenic? Posted: 03 May 2017 12:53 PM PDT My understanding is that most of a metal "allergies" are caused by irritation due to the metal's oxide. Even though these metals are considered to be relatively unreactive, they can still be oxidized. If this is the case, why are they less likely to cause problems? submitted by /u/livelytostito [link] [comments]
