| Posted: 11 Oct 2018 05:00 AM PDT I'm referring to this graphic, the incoming radiation absorbed by the surface, how can the energy emitted by the surface be greater than this? How is the energy amplified, isn't it a violation of the 1st law of thermodynamics? I'm sorry, this is a stupid question, I just couldn't find anything online why it is higher. [link] [comments]  |

| Is there an opposite period to an ice age? Posted: 10 Oct 2018 05:52 PM PDT Would it be a greenhouse age? And would we be heading to warmer temperatures regardless if global warming was occurring? [link] [comments]  |
| Posted: 10 Oct 2018 01:44 PM PDT Okay, let's start simple: If the world only consisted of positively charged particles and the electrostatic force was attractive, surely we could follow the same process that led Einstein to his view on spacetime, right? It's just a matter of substituting masses with (positive) charges and gravitational constants with electrostatic ones. Now let's drop the "assumption" of an attractive electrostatic force, but keep the world with only positive particles. To me it seems like this is not that different. Of course, the behaviour of particles would totally change, but instead of moving closer together positive particles just tend to move away from each other. Could we still describe this similarly to the curvature of spacetime due to mass? As a last step, we have to allow negatively charged particles into our imaginary world. Intuitively, I'd say this is the most difficult step, and since we don't have a unified theroy, I don't think we can do this (yet), right? [link] [comments]  |

| What is a GEO satellite's position on its analemma called? Posted: 11 Oct 2018 02:12 AM PDT I work in communications management for the military. While I understand most of the basics, SATCOM is still one of my weak areas. My team was explaining to me the importance of hitting a satellite while it's on its "zero point", which allows us to maintain good signal strength on the satellite without having to adjust the antenna every few hours as it moves on its analemma. If we hit the satellite when it's on one of the extreme points of the analemma, we lose sat lock and have to do another peek and poll to find it again, which is why it's best to get it at its zero. They told me this data is (at least for commercial satellites) almost always available for look up as the path the satellite traverses rarely changes. They mentioned what they think the data is called but a quick google search returned zero results. They called it something that sounded like "infemeris data". I'm just curious at this point if there is a specific name for this data so I can hold onto this knowledge. Thanks! [link] [comments]  |
| Why does water expand when it cools instead of shrinking? Posted: 10 Oct 2018 05:58 PM PDT Every other element else that goes through a negative enthalpy change shrinks in volume so why doesn't ice? [link] [comments]  |
| Can a hydrogen atom have more than two electrons at a given time? Posted: 10 Oct 2018 08:49 AM PDT We know that that hydrogen usually has only one electron in its outer shell but can hold two, hence why it's fairly reactive, in order to bond with other elements and get the second electron. But now another question bugs me: can we tack on more electrons? If so, what would happen? [link] [comments]  |

| Can old plastics spontaneously explode? Posted: 10 Oct 2018 09:53 AM PDT I was listening to the 99% Invisible podcast, at about 19:30 someone (Emma McClendon?) says the following (my transcription, please forgive any errors). I did a few Google searches but couldn't find anything more. "This is what people need to realize, plastics sometimes age in such a way that they are attempting to go back to a gas or they want to go back to a liquid. So that means that if you feel your sneaker sole that you've had for a really long time begins to stick to the floor you should get rid of it because it is what we would call weeping or other terminology. It's going back to it's liquid state. It's toxic, you don't want to touch it. Same with something if you keep a plastic comb or barrette or a Tupperware container, you never know, in an airtight drawer, say you don't open it for years, and then you open it and you find shards it means that it exploded. It literally combusted at some point and you will smell it. These things are giving off noxious fumes. And again we don't tend to see this because we see plastic as disposable but that's what this stuff is doing in these landfills." https://99percentinvisible.org/episode/blue-jeans-articles-of-interest-5/ [link] [comments]  |
| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 10 Oct 2018 08:11 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology 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]  |

| Posted: 10 Oct 2018 11:02 AM PDT It would never appear in the night sky (or the day sky!), and its gravitational pull would be in exactly the same direction as the sun. Would we have to go out there and check? Have we checked? [link] [comments]  |
| Does “fast charging” or “slow charging” actually effect the duration of a battery charge? Posted: 10 Oct 2018 11:52 AM PDT Mainly referring to charging him of cell phone batteries. House chargers (which charge slower) vs car chargers (charge faster). Using today's current batteries as the battery of interest. [link] [comments]  |
| How powerful are modern quantum computers? Posted: 10 Oct 2018 11:50 AM PDT I remember shortly after the development of quantum computers began they were having trouble performing simple arithmetic. How powerful is quantum computing now that there has been significant research over the past several years? I saw this nature paper (https://www.nature.com/articles/s41598-018-33125-3#Abs1) talking about how a quantum computer was used to simulate basic artificial lifeforms, which sparked my question because I wasn't aware we could do such things with them.

| Does Norton's Dome prove indeterminism in Newtonian mechanics? Posted: 10 Oct 2018 11:18 AM PDT Or is the solution given in the paper ( r(t) = 0 for t<=0 and r(t)=(t-T)4 /144 for t=>0 ) simply invalid, because it is discontinuous for d4 r(0)/dt4 ? [link] [comments]  |
| How reliable is Doppler Radar velocity data for estimating surface winds for a Tropical Cyclone? Posted: 10 Oct 2018 10:40 AM PDT As Hurricane Michael is currently making landfall on the panhandled Florida, Doppler Radar from Elgin AFB has shown some velocity readings near 165 mph or greater. I know this is not true surface measurements, but how does it compare? [link] [comments]  |
