Why Do Certain Chemicals Cause Different Individuals To Experience Similar Complex Thoughts/Hallucinations? Where Is The Information Coming From? Posted: 03 Aug 2017 12:20 AM PDT So, I've come across 2 chemicals that regularly cause people to all have similar complex hallucinations. Tetraethyllead - when workers were exposed to hazardous concentrations of the chemical, they contracted lead poisoning, but all reported having a similar hallucinations of "being eaten alive by butterflies". DMT - many uses report seeing "machine elves" when they are hallucinating. My question is: these aren't merely symptoms like stomach pain, or generalized hallucinations like seeing flashing colors, etc. These are complex thoughts. How is it that different people can all experience the same complex thoughts from a simple chemical? Clearly the information isn't being transmitted by the chemical itself... but it's almost more unlikely that the same information is present in everyone's brain waiting for the chemical to trigger it. Such would suggest that everyone has the same "I'm being eaten by butterflies" receptor in their brain, waiting to be activated by TEL. Or is it just that these drugs all affect the brain in some simpler way and everyone just has the same predictable way of making sense of the hallucinogenic effects? But then what's there to differentiate one hallucinogen from another? Why does DMT cause people to hallucinate "machine elves", but other hallucinogens don't? submitted by /u/Suozlx [link] [comments]

Does a multi-decade concentration of Radon gas lead to an accumulation of lead particles in an enclosed environment (basement)? Posted: 03 Aug 2017 06:09 AM PDT I was looking at the decay chain for Radon, and noticed that the first stable element in the chain is lead 210. So if a basement, for example, has high Radon levels for, say 100 years, would that create a higher than normal concentration of lead in that enclosed environment? submitted by /u/kickturkeyoutofnato [link] [comments]

What would a finite positively curved universe mean for the twin paradox? Posted: 02 Aug 2017 05:54 PM PDT So my understanding of the twin paradox is that there are two twins, A and B, A stays on earth and B goes off on a spaceship at 99% the speed of light. From A's perspective, B is travelling at 0.99C, and so clocks on B's spaceship are running slowly, meaning B ages less. But from B's perspective, A is travelling at 0.99C in the opposite direction, meaning B sees these effects happening to A instead. From both reference frames, the other twin is ageing slower, and so the paradox asks: who has aged less when the twins are reunited. The solution to this paradox is that B has to accelerate in order to turn around and come back home. This acceleration means that B is no longer in an inertial reference frame, and so this solves the paradox. BUT. In a positively curved universe, you would not need to turn around and accelerate to come back home. If you travel in one direction for long enough, you would end up back where you started, the same way an ant walking around the surface of a sphere in one direction would end up back where it started. Who would be older and younger when twin B arrives back at earth? submitted by /u/Kelan_ [link] [comments]

How have continents survived plate tectonics for this long? Posted: 02 Aug 2017 08:59 PM PDT If plate tectonics "recycles" the Earth's crust by subsuming and melting down plates, and then generating new material elsewhere, how the heck have the continents/plates as we know them survived so long? I remember seeing a map of Pangaea breaking up (something like this: pic) and being amazed that basically every recognizable landmass on Earth just basically slides around from one place to another, nothing lost, nothing gained. I dug around a bit on Wikipedia for other supercontinents. The 1.59 billion year old "Columbia" has much, much less recognizable land (pic#/media/File:Paleoglobe_NO_1590_mya-vector-colors.svg)) but still, there are many parts that still exist on Earth. What am I missing here? How do parts like Greenland, West Africa, and Antarctica move north, south, east, and west all over the freaking globe for 1.59 billion years without being recycled? submitted by /u/wankbollox [link] [comments]

How long is the actual process of supernova explosion? Posted: 02 Aug 2017 09:03 AM PDT So we have the well known Betelgeuse star which is getting close to a supernova stage. My question is, how fast is the actual process? I know that it is probably a bad question since the actual explosion takes only a few moments but I want to know for example how long will it take from the actual explosion (visible from earth) to it expanding over let's say 1 degree in the sky? submitted by /u/RudaBaron [link] [comments]

Do all currently-living things share a single common ancestor? Posted: 02 Aug 2017 09:41 PM PDT I know that generally all life is thought to have a Last Universal Common Ancestor, but was that most likely a single individual? Or is it more likely that early primordial life arose via multiple events, and therefore no matter how far you go back there are currently-living organisms that never shared an ancestor?

How is it that you can compress TBs of data into small easy to move zip files? Shouldn't the data take up the same amount of memory all the time?

How and why does entropy change during adiabatic magnetisation and subsequent demagnetisation? Posted: 02 Aug 2017 12:05 PM PDT I am an A-level student trying to do some wider reading and came across the magnetocaloric effect. I was reading this article and got confused in the first paragraph where is is stated: the isothermal compression of a gas (we apply pressure and the entropy decreases) is analogous to the isothermal magnetisation of a paramagnet or a soft ferromagnet (we apply H and the magnetic entropy decreases), while the subsequent adiabatic expansion of a gas (we lower pressure at constant entropy and temperature decreases) is equivalent to adiabatic demagnetisation (we remove H, the total entropy remains constant and temperature decreases since the magnetic entropy increases). I suppose I was mostly wondering why the temperature decreases instead of the total entropy during demagnetisation but was also wondering how to conserve entropy in both the adiabatic expansion of a gas as well as in demagnetisation. Thanks in advance. P.S: Any good recommendations on places to start on becoming familiar with thermodynamics (so I don't have to pester you guys) at a level appropriate to me would be greatly appreciated. submitted by /u/destroyerking492 [link] [comments]

At what level of entropy does a system of a given size collapse into a black hole and how much data could be put on a flash drive before it collapsed into one? Posted: 02 Aug 2017 05:51 AM PDT I don't exactly understand it, but I recall hearing somewhere that a black hole can be defined as a region in space where entropy has exceeded a certain value. Since entropy is congruent to information, and in light of IBM's new 300TB storage drive, it got me wondering how much data could fit on a flash drive (say 3cc) before it collapsed into a black hole? submitted by /u/ThornOfCamorr1 [link] [comments]

What is the environmental impact of air conditioning? Posted: 02 Aug 2017 08:25 AM PDT My overshoot day question is this - how much impact does air conditioning (in vehicles and buildings) have on energy consumption and production of gas byproducts that impact our climate? I have lived in countries (and decades) with different impacts on global resources, and air conditioning is a common factor for the high consumption conditions. I know there is some impact, and it's probably less than other common aspects of modern society, but would appreciate feedback from those who have more expertise. submitted by /u/skleats [link] [comments]

Shouldn't time dilation prevent the creation of a black hole? Posted: 02 Aug 2017 12:01 AM PDT Because of relativity, the effects of time should almost stop at the event horizon.

Why is the August 21st eclipse going to move from West to East across the United States? Posted: 02 Aug 2017 05:58 AM PDT The earth is rotating relatively rapidly in an East to West direction.

Do black holes and crystals exemplify two extremes of entropy? Posted: 02 Aug 2017 07:47 AM PDT My base understanding is that entropy is a measure of the possible states of all elements in a system. If this is correct, is a black hole system very entropic and a crystal system very un-entropic? Is there anything more extreme than these? Is quantum foam more entropic than a black hole? Does anything exist which is less entropic than a crystal? So many questions... submitted by /u/fiji1221 [link] [comments]

Why don't glow-in-the-dark objects release their stored light energy all at once? Posted: 01 Aug 2017 11:48 AM PDT I understand that glow-in-the-dark objects/coatings store light energy by excitation of electrons to a higher orbital, and that when the electron drops to it's base orbital it releases the energy in the form of photons. My question is, why don't the electrons all drop simultaneously when the energizing light source goes away, resulting in a single instantaneous pulse of light, and then darkness? submitted by /u/FuriousCoder74 [link] [comments]

[Mathematics] (Also physics) Why can one define parallel transport without a metric? Is there a proof that it is a diffeomorphism invariant? Posted: 01 Aug 2017 02:08 PM PDT Hi! So I've been reading about gauge theories and the problem is, normally physics texts just assume all the geometrical data on the spacetime manifold is available. The setup of a gauge theory is a principal bundle E -> M over the spacetime manifold. On my side, I am studying about Chern-Simons theory, which is a topological field theory known to be diffeomorphism invariant. However, the Chern-Simons action depends on the connection form. I have trouble putting these things together: a connection form uniquely defines a notion of parallel transport. However, parallel transport is very clearly not diffeomorphism invariant. I can deform the curve-to-be-lifted however I want, hell, I can even change the start and ending point via diffeomorphisms. This means that the connection form should not be diffeomorphism invariant. So why on earth does the Chern-Simons action define a topological field theory? :D Thanks! submitted by /u/fuckwatergivemewine [link] [comments]

What are the specific mechanisms of heavy metal ions denaturing or inhibiting enzymes? Posted: 01 Aug 2017 01:59 PM PDT I have heard about other metals replacing ligand bonded ions that "belong" in the enzyme originally, and ions attacking disulphide bridges changing the form of the enzyme, as well as just more generic "ion binds somewhere and changes the shape of the active site". Problem is, I can find a lot of places mentioning these things but not too many sources that actually explain what is happening. Which ones are correct? Are there other possible mechanisms as well? Is the disulphide bond mechanism denaturing or just inhibiting the enzyme? Can any heavy metal ion act as a denaturing agent or an inhibitor?

How did Bekenstein develop the equation of a black hole's entropy? Posted: 01 Aug 2017 09:55 AM PDT I've gotten as far as working out the Planck area from dropping single photons into a black hole, but I have no clue how to get from there to entropy. I know entropy is practically without units, but there are many ways I could mess with the formula to create something without units, and it would likely be meaningless. How did Jacob Bekenstein know which way to arrange the formula to describe entropy? submitted by /u/DarkFireRogue [link] [comments]

Nucleosynthesis via Tidal Breakup of Neutron Stars? Posted: 01 Aug 2017 09:51 AM PDT I know that neutron stars contain a lot of nucleons below the surface that aren't bound to a specific nucleus. I also know that a neutron star will break up if it passes too close to a black hole. In such a situation, pieces of the neutron star might be ejected. What would the isotopic composition of the resulting debris look like? Would we see isotopes that are usually too neutron-rich to form? A literature search turned up this conclusion from 1976. "At present it is unclear [what] distribution of heavy elements result, although it seems safe to conclude that neutron-rich heavy elements themselves do result" - Lattimer & Schramm, Astrophysical Journal, vol. 210, page 562 submitted by /u/Bucky8s [link] [comments]

What is the relationship between M theory, string theory and supergravity? Posted: 01 Aug 2017 10:18 AM PDT Ok so it was a few years ago and i watched a really interesting documentary about M theory. In it was discussed how string theory and supergravity theory were at odds for a long time with one of the main distinctions being how many dimensions of time and space there were. IIRC they said string theory had for a long time used 10 dimensions wereas supergravity used 11. Then when they used string theory and added to their equations the 11th dimension proposed by supergravity it made a new and much more "elegant" theory wherein instead of strings it became a membrane. Hence the name m theory. When i search tho i cant find this documentary and searching m theory just brings up string theory which i (likely incorrectly) thought had replaced string theory as the prevailing modus operandi in quantum mechanics. Am i wholly incorrect in this thought? If so what is the real relation btwn the 3? Thank you so much in advance and if any one has some recent documentary suggestions on this it would be greatly appreciated. submitted by /u/chaz_almasy [link] [comments]

What purpose does chilling the instruments of a telescope serve? Posted: 01 Aug 2017 03:09 AM PDT Let me preface this with I have no formal education in advanced physics or engineering or astronomy or anything relative to this question/questions. My background is in biology focusing on zoology, so please forgive me if I use incorrect terminology in relation to measurements or any other lingual blunders I may commit. OK, so I know I'm way behind on this one, but I've only just started looking into it. My question is about the Lucifer Telescope. Why is it necessary to chill the instruments to about -351 ℉ (I'm American and this unit of measurement for temperature is what's most comfortable for me in terms of comprehension. I'm sorry) to make near infrared observations? What is the relationship between the temperature of the instrument, the temperature of the galaxy/universe (I guess -455℉), and the ability to observe near infrared wavelengths? Is the telescope used to search within different wavelengths? Or is none of this even a thing and they're just chilled because it is a very high powered telescope requiring a lot of cooling? Again, I apologize if these questions are gibberish, just trying to find the right way to word this with such limited knowledge of proper terminology to convey what I'm asking has been exceedingly difficult. Thank you. submitted by /u/smellexisb [link] [comments]

What conclusion can be drawn from statistically insignificant results? (Layman question and text provided) Posted: 01 Aug 2017 04:43 AM PDT Hello guys, I just wanted to ask you if somebody could give me very basic (layman) explanation about one question. If for example you did an experiment on yourself where you tried a drug to see if it helps you with your condition, you took it 100.000 times but it only helped you 3 times. What conclusion can you draw from this? Is the result statistically not significant and therefore the hypothesis that a drug helps you can be rejected (so you can conclude that this drug doesn't help you). I know this is a very lame example, but try to give me an explanation for this particular scenario. It seems logical for me to conclude that a drug doesn't help, but I want to see it backed up by science. Thanks in advance! submitted by /u/Ambush995 [link] [comments]

Why do different species have different lifespan? Posted: 31 Jul 2017 09:11 PM PDT ^ For example: Dogs have an average lifespan of 10-13 years; Sea Turtles have 80 years lifespan whilst humans have est. 30-50 years lifespan(without medicine). Why are they different? Is it because different species have evolved differently and our body cells are 'programmed' to die/weaken at a certain point in our life? If so, was/is/would there be a species that would evolved in a certain way to be 'programmed' with a very long/infinite body cells' lifespan?

Does climate change effect the occurrence of different cloud types? Posted: 31 Jul 2017 11:19 AM PDT Here in Europe the weather is said to become more extreme regarding storms and rain. Does this effect the types of clouds we see in the sky? Like, types that are somewhat "extinct" or will become so? submitted by /u/neurotroph [link] [comments]

Why are there no neutrons in a hydrogen nucleus? Posted: 31 Jul 2017 09:58 AM PDT I know deuterium and tritium exist, I want to know specifically why the most common form of hydrogen has no neutrons. submitted by /u/wondersanchez [link] [comments]

What happens to the mass of two supermassive black holes when they merge together? Is it simply the sum of both black holes or does it become more/less dense? Posted: 31 Jul 2017 11:12 AM PDT submitted by /u/FuzzyDuckBug [link] [comments]

How does one find the activation threshold of a diode? Posted: 31 Jul 2017 04:45 PM PDT I've been tinkering with some electrical circuits as inspired by my physics class and while graphing some different kinds of diodes under rising voltage, I noticed the before they come a mostly constant resistance they a sometimes slow, sometimes fast ramp up, looking a lot like an exponentional function. What causes this behaviour, when in theory they should just have 1 activation voltage? If I wanted to find the specific voltage myself, do I simply take the point with the lowest amount of current, or do I compensate for the ramp up somehow? I feel this is tied to my imperfect understanding of what exactly a semiconductor is submitted by /u/TheGibber [link] [comments]
