| Posted: 17 Aug 2016 10:11 PM PDT A friend of mine recently learned his Pokemon Crystal cartridge had run out of battery, which prompted a discussion on data storage with and without electricity. Can anyone shed some light on this topic? Thank you in advance! [link] [comments]  |
| Could you tell that camels have humps just by looking at their skeletons? Posted: 17 Aug 2016 08:03 PM PDT Like, say you had some archaeology students who were raised in a bunker and were taught everything about how to discern external anatomy from skeletal structure, but never taught that camels existed. If they were given a camel skeleton, could they geuss that it had a hump? [link] [comments]  |
| Posted: 18 Aug 2016 06:28 AM PDT If we know black holes emit radiation and would eventually evaporate given an absurdly long period of time, is there a point at which enough mass has left and it's no longer a black hole but just another very dense and potentially visible body of matter? Say for example a star, with what we think of as the minimum mass capable of forming a black hole, is literally in the middle of nowhere and it collapses into a black hole. It would have no matter to feed on and would therefor be decreasing in mass immediately due to radiation. It's my understanding that a black hole is finite mass in a volume approaching 0. Does this mean that once it collapses to that near infinite density, it will never cease being a black hole with an event horizon until the very last particle has evaporated due to it's near infinite density? If this is the case, will we just end up with a black hole whose event horizon also gets incredible small? Would this mean there might be black holes out there that have event horizons a few feet in diameter or something crazy small like that? [link] [comments]  |

| Why does ice have a lower resonance frequency than rocks? Posted: 17 Aug 2016 06:46 PM PDT Is it just because it's solid H20 or do other frozen substances have low resonance frequency as well? [link] [comments]  |
| At what altitude above Earth do the effects of Special and General relativity cancel each other out? Posted: 17 Aug 2016 07:43 AM PDT First, if this question doesn't make sense, please tell me, because I am going under some very rocky understandings of special and general relativity. So as I understand it, in special relativity, the faster someone moves, the slower time is for them, relative to someone who is stationary. In general relativity, the further away you are from a massive object, let's use the Earth, the faster time will move for you, relative to someone on Earth. So astronauts on the ISS age slower relative to us because they are moving extremely fast, but aren't at a high enough altitude for the effects of general relativity to overcome the effects of special relativity. However, for GPS satellites which are in a higher orbit, the opposite is true. THE QUESTION So at what orbital altitude do the effects of special relativity and general relativity cancel each other out so that no time dilation occurs relative to a man on Earth, assuming that the orbit is perfect, with the apogees and perigees being equal? Or do I not understand something here? Edit: Thanks for the gold, but I think agate deserved it more. [link] [comments]  |

| Why does it cost so much to send trivial items to space? Posted: 18 Aug 2016 04:21 AM PDT I'm asking this because I was browsing /r/space and someone was talking about the statistics for the price of sending 1 kilo to space. They then claimed to send a pencil to space costs 550 dollars. How is this? Does this mean that if I accidentally have a pencil in my pocket when I go to space, someone will be out 550 bucks? Or will we just not make it to orbit? [link] [comments]  |
| Posted: 17 Aug 2016 04:03 PM PDT Children, teenagers, and adults have different methods of learning that are effective for their brains, and they are all capable of becoming fluent in a foreign language. But it's often mentioned that children are able to obtain native accents whereas adults are not expected to. Ignoring things like not having as much time, is there any cognitive/psychological/neurological explanation for this supposed discrepancy? [link] [comments]  |

| Where do fish in high altitude/mountain streams and ponds come from? Posted: 17 Aug 2016 07:20 AM PDT I've been hiking in Europe and Asia and have seen fish even in tiny puddles at very high altitudes, close to the ice cap source of the river. How the hell do they get here? Surely both migration and reproduction is incredibly difficult against a current and in such isolated bodies of water [link] [comments]  |
| Posted: 17 Aug 2016 09:35 PM PDT LIGOs such as those in Hanford, WA and Livingston, LA are currently able to detect gravitational waves by measuring the time it takes for two laser beams to travel through two 4 km perpendicular tunnels (let's call them x and y). If I understand correctly, when a gravitational wave is detected, the data from x and y can be used to narrow down the direction of the wave's origin, especially when data from both LIGO locations is considered. The current ability to calculate the direction of origin does not seem to be very accurate and has only a 90% probability according to the diagram on this page. Would adding a third laser detector in a vertical "z" dimension much improve the accuracy of their direction of origin calculations? Apologies if this is long winded, I just want to be as clear as possible. Thanks in advance! [link] [comments]  |

| Posted: 17 Aug 2016 05:16 AM PDT Inadequate registration of events example: a person who doesn't care enough about the topic that's being discussed, and just not 'absorbing' the information as memory. Inadequate indexing: a person who does not store the memory with proper indexing or reference at the experience moment, or a person that's having problems retrieving the experience in retrospective due to poor indexing/accessibility. Inadequate storage of memory is kind of self explanatory. [link] [comments]  |

| How does time reversal symmetry apply to quantum mechanics ? Posted: 17 Aug 2016 07:51 AM PDT I'm currently listening to an audiobook of Leonard Susskind's "The Black Hole War". In it, Susskind discusses the time-reversability of classical physics while introducing the idea of conservation of information. That's all pretty straight forward, but he doesn't really get into how it applies to quantum physics, as the answer may be too math-heavy for the sort of book he intended. If I've understood him correctly, he simply states that as long as you do not interact with a system before time-reversing it, any result that QM gives you is reversible. I wanted to think about this in terms of the double slit experiment. If you attempt to time-reverse the experiment, your target emits a photon from some random spot, and the photon passes through the slits. In a normal picture, the photon should interfere with itself at this point, just like the forward experiment, but in reality, it b-lines towards the emitter. Clearly not symmetric in time. Which makes me think, collapsing the wave function at the target at the end of the experiment was the step that broke the reversibility. If you had the whole interference pattern intact, I'd bet you could reverse out the initial trajectory (slits -> emitter). Is that right? If it is, is wave-function collapse always non-reversible? Is there a larger context in which it is reversible? (e.g. Many-Worlds) Also, why is it seemingly okay to pretend it doesn't happen and still claim that QM is still time reversible? Isn't wave function collapse destroying information all the time? [link] [comments]  |
| Do flashlights and lasers have a recoil? Posted: 17 Aug 2016 02:14 PM PDT We know that light exerts physical pressure on objects in its path. But does the "launching" of light cause a recoil? If I were in a completely dark room and I turned on a flashlight or a laser pointer, would there by an (absolutely minute) amount of "backpressure" on the flashlight caused by the releasing of the photos in a single direction, in the same way that firing a bullet causes a recoil of the gun?

| Why is hydrostatic pressure only dependent on depth? Posted: 17 Aug 2016 10:43 PM PDT Hi AskScience, I've proven this to myself mathematically (from P = F/A ultimately to P = pgD) but I can't fully grasp it conceptually. I've googled this question but I can't find a very eloquent answer Conceptually, why is it that the pressure at depth D is the same in a cylindrical tube, a triangular container, and a container, for instance, like an upside-down T? Thanks in advance [link] [comments]  |
| How does silicone stick to skin? (Like in strapless bras and medical pads) Posted: 17 Aug 2016 05:53 PM PDT I have a silicone pad for my foot to relieve pressure on a morton's neuroma. I'm curious how the silicone is able to stick so well and how it's able to be washed and reapplied. What is the specific mechanical action that's occurring on a microscopic level? There isn't a chemical aspect is there? [link] [comments]  |
