| How large does building has to be so the curvature of the earth has to be considered in its design? Posted: 27 Feb 2019 03:40 AM PST I know that for small things like a house we can just consider the earth flat and it is all good. But how the curvature of the earth influences bigger things like stadiums, roads and so on? [link] [comments]  |
| Is elevation ever accounted for in calculations of the area of a country? Posted: 26 Feb 2019 10:19 AM PST I wonder if mountainous countries with big elevation changes, like Chile or Nepal for example, actually have a substantially bigger real area, or if even taking in account elevation doesn't change things much.

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 27 Feb 2019 07:11 AM PST 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: 27 Feb 2019 07:01 AM PST I have done my fair share of trying my best to understand this issue, primarily to help explain to relative/friends/co-workers which are 'non-believers' but the truth is that I must not truly understand the issue either. I feel as though all of those skeptical also see "the charts for temperature rise, the scientific models for the future, and the consensus statistics of scientists agreement of climate change happening rapidly", but if you really think about it - none of those things give reasoning or logic as to WHY this is happening. They are just things that you see that show it is happening. I had one co-worker give me the classic argument, "well yea that chart shows the temperature is rising but that doesn't mean CO2 is causing it." Another statement I get when trying to explain, "The models the scientists have may agree, but you know how many assumptions we have to make for our models here [at work, engineering], imagine how many assumptions they have to input for the globes climate and atmosphere/ocean circulation. WHY is climate change occuring due to CO2, Methane, Water vapor, etc...?? Do the molecules vibrate or hold vibration (temperature?) longer than simple air (O2, N2, etc etc)?? Is it because CO2 is more dense and therefore creates a denser environment which in turn holds the heat down on the surface easier?? Any insight is appreciated. I would like to be able to debate those without facts and actually be able to explain. If this takes further education/reading on my part, I'm not afraid to spend time learning. I hope my question makes sense. Any responses like "It happens because CO2 causes warming" obviously don't understand why I'm asking. I'm asking why that exists. This is my plea for logical understanding. Thanks in advanced for your help. [link] [comments]  |

| Posted: 26 Feb 2019 03:10 PM PST So Gibbs' free energy is the maximum reversible work that can be produced in a thermodynamic system at constant P and T, and according to the formula, higher T means lower ΔG. Then why is Superheated steam used as means to produce work? Or am I looking at it wrong? [link] [comments]  |
| What is the exact difference between genotype and karyotype? Posted: 26 Feb 2019 10:17 PM PST When I say "genotype" I'm referring to the entirety of the chromosomal configuration or said differently, full genetic makeup of a human.... full, not just one aspect as I've seen used in some cases. Given that we're using genotype in that context, what is the difference between genotype and karyotype? [link] [comments]  |
| Why do gravitational lenses sometimes result in Einstein-crosses rather than full circles? Posted: 26 Feb 2019 08:09 AM PST In what way can the light be "bent" by a gravitational lense so that an observer sees two (or more) copies of the object rather than seeing a full circle? E.g. in Einstein-crosses you see 4 copies spaced evenly around the center. What about the spaces between those 4 copies? Why does the light not take these ways? (Btw I asked this several times in different places now and never got an answer, sometimes I just got downvoted - I hope this sub is the right place) [link] [comments]  |

| Can solar panels run out of electrons? Posted: 26 Feb 2019 01:50 PM PST I understand that photons "bump" electrons, that the movement of electrons transform solar energy into electricity and that the electrons first come from the silicon in the solar panel, but do the electrons leave the solar panel since they are the current? If so, can a solar panel get its electrons back or is it doomed to die even if nothing else fails? If not, do the electrons stay in the solar panel somehow? [link] [comments]  |
| Posted: 26 Feb 2019 09:37 PM PST I know penicillin targets transpepidation, but how do the two differ? What makes one more effective than the other? [link] [comments]  |
| If you placed a Foucault pendulum at the equator, would it fully rotate in one year? Posted: 26 Feb 2019 04:45 PM PST So I know the earth rotates under the pendulum, which majes the pendulum appear to rotate to us. What I wonder is if you put a pendulum at the equator and ran it for a year, would it fully rotate or nearly fully rotate over the course of the year? Although at the same time with this logic, it might seem that the foucault pendulum will have to become upside down instead of rotating. Does the pendulum do anything interesting?

| Can a pair of binary planets share an atmosphere without exceeding the Roche Limit? Posted: 26 Feb 2019 05:19 AM PST Can the distance between a pair of binary planets be close enough that the gasses making up their atmospheres could mix at the L1 Lagrange point, without either planet being pulled apart by their partner planet's gravitational field?

| What state of matter is light? Posted: 26 Feb 2019 09:51 PM PST Wave particle duality says that light is a particle or a wave depending on how it is observed. It also introduces momentum and mass for light. If light is clearly matter, which state of matter is it in? [link] [comments]  |

| How to quantify political/diplomatic relationships between countries? Posted: 26 Feb 2019 07:53 PM PST Hi, I'm not sure if this is the best place to ask this. I'm starting a project that will attempt to estimate the state of political relationships between countries through a set of data. The data set will comprise of certain keywords that indicate hostility, friendliness, etc. I was wondering if there was some equation or theory, paper, idea etc that could help me develop one. I'm searching for something similar to the Drake equation, or a comparable idea. Any help would be greatly appreciated. [link] [comments]  |
