| How finite are the resources required for solar power? Posted: 22 Nov 2016 09:02 PM PST Basically I am wondering if there is a limiting resource for solar panels that will hinder their proliferation in the future. Also, when solar panels need to be repaired or replaced, do they need new materials or can the old ones be re-used? [link] [comments]  |
| Dumb (?) Questions about Coding and Linguistics Posted: 23 Nov 2016 06:37 AM PST Is computer code a 'language'? If so, are there different codes or ways of coding that serve the same purpose but are different only insofar as they use different types of 'grammar'? If yes, then how are these new codes created? Are they, themselves, coded via pre-existing codes? For example, does one use 'code A' to create 'code B', after which 'code B' no longer requires 'code A' and can, furthermore, replace it for all intents and purposes? (Do codes serve as the tools of their own obsolescence?) Finally, assuming that my prior assumptions are, at least in part, accurate, how was the first code created if none already existed? In other words, how do you make a code without using another code? Thanks for your time and consideration and I'm sorry if none of this even remotely makes sense. I created a Reddit login just so that I could ask these questions. [link] [comments]  |
| Why handgun bullets are rounded? Posted: 23 Nov 2016 02:40 AM PST I've seen plenty of handgun bullets but I actually have never seen one of them being pointy as a rifle bullet. It seems counterintuitive to me why two things sharing same purposes have to be so different in their shape. Example images: * Handgun ammunitions *Rifle ammunitions [link] [comments]  |
| Viral strains "replace" others? Posted: 23 Nov 2016 12:15 AM PST In this article from the US National Institutes of Health, I read the following:
How does it happen that a flu strain replaces its predecessors? Are they actively "fighting" among each other? Are they competing for finite resources? Does the immune response for H3N2 end up fighting H2N2 and H2N1 more effectively? [link] [comments]  |

| Posted: 23 Nov 2016 07:09 AM PST Basically the title, but I'm wondering how the delay from my button press to a character's movement on another gamer's screen can be so small. What technology is primarily responsible for this incredibly small difference? [link] [comments]  |
| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 23 Nov 2016 07:05 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Engineering, Mathematics, Computer Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| What happens to light INSIDE a blackhole? Posted: 22 Nov 2016 04:52 PM PST If someone were to generate light from the center of a blackhole, does it just shoot to the schwarzschild radius and then orbit the blackhole? Or does it get reflected from the outer rim and then hit the source? I'm guessing since the blackhole has to have a speed of light c as its escape velocity (can't be higher or lower), the density inside is not constant, but gradually increases as you go towards the outside of it. But if it's doing that, and there's more particles, then shouldn't the speed of light just inside the blackhole be much slower than the speed of light in the vacuum just outside (acting like total internal reflection)?

| Why can I see an interference pattern in a well-lit room? (double-slit experiment) Posted: 22 Nov 2016 07:14 PM PST I have a simple setup like this one to see quantum interference. What I don't understand is that supposedly if I shine a light source on the slits, it will prevent the interference because which-path information is preserved. That's not the case when I try it but also I'm doing this experiment in a well-lit room. Why is it that the ambient light doesn't inadvertently preserve the which-path information and prevent the interference pattern from ever happening in the first place? Shouldn't a pitch black room be required to see interference? [link] [comments]  |

| What is the difference between a laser pointer and and a laser that can actually cut through things? Posted: 22 Nov 2016 06:47 PM PST I was playing around with my laser pointer and I was wondering if this thing, under different circumstances, could cut through something thin enough.

| How are rivers and lakes affected by global warming? Posted: 23 Nov 2016 04:55 AM PST We've all seen the apocalyptic predictions of sea encroachment into areas like the American South and the European Low Countries. My limited understanding is both icecap melt and the change in ocean water volume are to blame. I am wondering what effects the predicted change in temperature has on inland bodies of water, such as streams, rivers, and lakes. Will rainfall be different? Evaporation? [link] [comments]  |
| Posted: 22 Nov 2016 10:35 PM PST Assume a completely flat surface. Since you can jump on Earth and sprain an ankle, I'm guessing the same could happen in this scenario too. All injures like this aside, would your momentum from falling be enough to cause a greater impact that the human body could withstand? [link] [comments]  |
| How does the stock market affect the wealth inequality in the world(top .1% etc.)? Posted: 23 Nov 2016 04:24 AM PST More specifically: How did the invention of mathematical models such as the one by Black-Scholes, affect the stock market and different financial crisis around the world?

| Why is it that looking at a specific object moving among many makes its movement appear slower? Posted: 23 Nov 2016 02:29 AM PST For example, if you were driving by a field, all the plants appear to be speeding by, but the moment you focus on a specific plant, it seems to go by more slowly. Is this an example of chronostasis? [link] [comments]  |

| Why do my kitchen sponges get warm when I spray them with hydrogen peroxide? Posted: 22 Nov 2016 01:59 PM PST Recently I've taken to spraying my nasty kitchen sponges with hydrogen peroxide to sanitize them. They foam up--which I expect, given that they are teeming with bacteria; but then, when I go to wring them out, they are warm. Why do they get warm? [link] [comments]  |
