| What is the Correlation length of Temperature? Posted: 14 Dec 2017 05:55 AM PST Cities that are close to one-another will have temperatures that are correlated; a hot day in one will likely be a hot day in the other. Cities that are farther apart will generally have uncorrelated temperature, except due to global fluctuations (December is colder than July in both New York and LA). So, what is the typical correlation distance of temperature? Just playing around with Wolfram Alpha, Chicago and New York look uncorrelated, New York and Boston are totally correlated, whereas New York and Detroit are weakly correlated. So, I estimate the correlation length at about 1000 km, but I imagine it's different EW vs NS. [link] [comments]  |
| Why is going on your tip-toes easy, when doing a push-up is difficult? Posted: 13 Dec 2017 08:35 PM PST I was just sitting in a position like this and was slowly raising and lowering myself on my toes as a sort of stretch. After a little bit, I began kind of freaking myself out, because it feels like I'm lifting my entire bodyweight using only my toes. Why is this so simple to accomplish, when a different way of moving your body up and down (a push-up) is relatively difficult? DISCLAIMER: I feel like this is a very dumb question. I wish I could say that I'm drunk or something, but no, I'm just in my room raising and lowering myself on my toes. [link] [comments]  |

| How can a supernova get brighter, even after it's "peak brightness"? Posted: 14 Dec 2017 03:47 AM PST I found a graph comparing the brightness of different kinds of supernova brightness'. The link is from another post in this subreddit and i don't claim any rights to it. I was just interested in how thy behave. Sorry for poor english.

| How much electricity can travel on a transmission line? Posted: 13 Dec 2017 09:26 PM PST I'm trying to understand electricity transmission using an analogy of distribution of water. In this case the transmission lines are the pipes, but what would their capacity be? If I say the lines are 138kV for example does thst give me any idea of how 'big' the pipe is, and therefore how much electricity I can transmit per unit time? Thank you! [link] [comments]  |

| How do we know black holes can die if we have yet to see it happen? Posted: 13 Dec 2017 04:40 PM PST I've been searching for a minute and I can find plenty of information suggesting that black holes will eventually evaporate, I can't find any info on when or where the evidence we have for it is other than extrapolated equations. I'm mostly just unsettled by the fact that I can't seem to find any evidence of black holes completely evaporating and I get worried about our universe. [link] [comments]  |
| Posted: 13 Dec 2017 09:33 AM PST the -admittedly brief- wiki page states that Chernobyl's Elephant's Foot "will remain radioactive for over 100,000 years". if cost and resource availability were not an issue, would there be any way to neutralize such an intensely dense and radioactive site/object overnight (or in a reasonably brief amount of time)? side question: what is currently being done about it, and in what ways are scientists trying to make future progress in dealing with it?

| Why do the bottoms of glass beer bottles pop off when tapped? Posted: 14 Dec 2017 12:57 AM PST I just saw this post https://www.reddit.com/r/instant_regret/comments/7jmhe4/there_is_always_that_unlucky_friend/ and I see that the top comment explains it as heating but I don't think that's it, looking at the delay, the heating may have made it weaker but I think it's the same effect. I have seen people do this with soda bottles before. For that matter I remember that post where the guy talks about what happens if a glass was actually half vaccum at the bottom and half water at the top. Is this similar in anyway?

| Posted: 13 Dec 2017 11:52 AM PST Given the general "noisiness" of everything happening within our own bodies, across the surface and within the atmosphere of the planet, and the relative "warmess" and "non-emptiness" of even interstellar space (bottoming out somewhere around 2.7 Kelvin and home to oodles of molecular hydrogen?), are the overwhelming majority of fundamental particles which compose matter always in a state of decoherence, and as such never exhibiting any quantum behaviour? I imagine that light, given that it obeys Bose-Einstein statistics is often exhibiting quantum behaviour during travel, but I really have no idea. Basically I'm wondering where and to what extent are quantum behaviours occurring "naturally" (ie. outside of controlled laboratory conditions). I'm just a layman with an interest, so I apologize if this question doesn't make too much sense, I'll try and elaborate if necessary. [link] [comments]  |
