| [Math] Is every digit in pi equally likely? Posted: 14 Mar 2017 11:11 AM PDT If you were to take pi out to 100,000,000,000 decimal places would there be ~10,000,000,000 0s, 1s, 2s, etc due to the law of large numbers or are some number systemically more common? If so is pi used in random number generating algorithms? edit: Thank you for all your responces. There happened to be this on r/dataisbeautiful [link] [comments]  |

| Posted: 14 Mar 2017 09:22 PM PDT So, my understanding of exponents is basically as follows. Say you have na/b. What this basically means is that you need to do two things to the number n - you need to multiply n by itself a-1 times, and then you need to take the bth root of that result. So, for example:
Ok, so that makes sense to me. You can then add on the idea that if either a or b is negative, you just do all of this stuff and then take the reciprocal. And so:
In order to do this, both a and b must be positive integers, because its an iterative process - you can't multiply something by itself 2/3s of a time. But usually you'll be able to express a/b in the form of positive integers. What doesn't make sense to me is that you can somehow take numbers to the power of things which are not rational (e.g. a/b can't be expressed as a ratio of positive integers) and therefore can't follow this step by step process. I guess there's two different categories here, which are:
Any insight would be awesome. Thanks! Note: I asked this question on /r/AskMath earlier, but didn't get very much of a response and got no answer to the second half of the question. Hoping I might get a better answer here. [link] [comments]  |

| Posted: 14 Mar 2017 03:53 PM PDT For example, if you take a picture from the surface of mars and the file size is 4 GB and then you send that picture to earth at 1GB a minute then that takes 4 minutes. If you split the data up into 4 parts of 1GB each and then send those 4 parts simultaneously on 4 different channels then the picture only takes 1 minute to get to earth. [link] [comments]  |
| What are the differences between waves? Posted: 14 Mar 2017 04:28 PM PDT I hear sound waves, I see light waves, and I would feel micro waves if they were in a high enough concentration. So what is the difference between then? [link] [comments]  |

| Black hole = magic refrigerator? Posted: 14 Mar 2017 05:53 PM PDT Assume I have a large black hole. And that I have an environment that is extremely hot due to photons flying everywhere. Let's say I build a giant machine to transfer those photons into the black hole. Not just in the immediate vicinity, but across a vast area. My question is, is there any limit to how large a machine the hole would be able to cool off by having the material transfer heat into it via radiators or similar. Like, if I built a machine much larger than the actual event horizon that is meant to pass heat into the hole, is there any reason in particular I can't cool the entire machine to the temperature of the hole? Like can I essentially use it as an unlimited thermal wastebin that gets colder and bigger the more heat I throw in it? [link] [comments]  |
| Do snow covered mountains still erode? Posted: 14 Mar 2017 07:21 PM PDT If the temperature on the mountain never reaches below zero, I figure the only source of erosion is the wind. But when the mountain is covered with snow, does it not act as a barrier between the wind and the mountain? [link] [comments]  |
| Aren't General Relativity and quantum mechanics just fundamentally, irreconcilably incompatible? Posted: 15 Mar 2017 01:06 AM PDT In GR, space and time are facets of a single "thing" and it seems to me that momentum pops out mechanically. There's no inherent limitation on measurement precision built into GR, just like in Newtonian physics. On the other hand, with Heisenbergian inequalities all over the place, we have to choose carefully what we try to measure simultaneously. These limitations on measurement are built right "into the code" of the universe. I just don't see how these theories could ever be unified when they don't even appear to speak the same language. Is there something I'm missing?? (besides, of course, an 8 years in a physics degree program at a university..) [link] [comments]  |
| Why does a screen recording program not crash when it records itself? Posted: 14 Mar 2017 07:00 PM PDT When a screen recording software, such as OBS, records itself, it creates a tunnel effect. If OBS infinitely records itself, why doesn't that make my computer crash/slow down? [link] [comments]  |
| Posted: 14 Mar 2017 08:27 AM PDT From what I gather, in string theory we naturally unify QFT and GR, so does it solve the problems that we encounter at a singularity? If so, what explanation does it offer when particles are broken down to their fundamental bits inside a black hole. Please shed light on how our understanding of black holes, and singularities would further if string theory is indeed true? [link] [comments]  |
| Can a neural network spit bars? Posted: 14 Mar 2017 03:57 PM PDT i was watching a video of a neural network learning to speak clearly and my first thought was "when this speaks english perfectly will it be able to rap?" since rap is heavy on the vocabulary it seems fitting to me to expand on my question, can a neural network rhyme, use word play and make references like a rap song does?

| Posted: 14 Mar 2017 01:58 PM PDT I understand (at a very high level) the life processes of a star, balancing gravity's pressure with fusion's outward-pushing energy, until (in some cases) the star begins fusing Iron, which is not an exothermic reaction, and gravity forces the mass of the star together past the Chandrasekhar limit where electron degeneracy pressure can no longer support the growing iron core, and boom. Hopefully I've got that mostly correct within the scope of this question. I've read that some low-metallicity stars of "only" several dozen solar masses can undergo core collapse and produce a black hole without a supernova - is that effectively what I'm describing in my question text? Or is that happening via some other process? What about when a really massive star collapses due to photodisintegration? Would that be an example of the text in my question, or is some other process occurring to create a(n) (apparently quite massive) black hole without a supernova in those cases? Are there any other theoretical cases where a star massive enough to produce a supernova and collapse into a black hole does not actually produce said supernova yet still collapses into a black hole? Or, worded another way (as I hopefully conveyed in the question text), the supernova occurs, but the star is so massive that the event horizon has already formed around the supernova? Sorry for so many sub-questions, just trying to clarify what I was originally asking and describe what I think I already know. EDIT: Changed flair to Physics from Astronomy; wasn't sure which applied better. [link] [comments]  |
