| What is unique about carbon that makes it ideal for organic chemistry? Posted: 18 Feb 2017 11:27 PM PST I understand that it bonds well molecularly with many other elements. What other elements could be the basis for advanced life (I've heard silicon might be suitable)? What qualities in an element might make it reasonably suitable? [link] [comments]  |
| Could the conditions for life be different than ours in another part of the universe? Posted: 18 Feb 2017 10:52 AM PST Basically, can other life forms in the universe exist without our specific standards of living. Is it possible for life forms to exist not dependant on water or oxygen? Why is our standard for looking for life on other planets if there is water on those planets or not? [link] [comments]  |

| Would the gravity on the moon closest to the earth be greater than the gravity on the opposite side? Posted: 18 Feb 2017 08:55 PM PST Was just thinking about this when i was looking at the moon and thinking about the gravity present on it [link] [comments]  |
| What evolutionary pressure is there for people with good looking faces? Posted: 19 Feb 2017 07:00 AM PST Why are some faces considered attractive? Why are people with certain faces more likely to survive? [link] [comments]  |
| How can you derive the positions of the heavy atoms in protein crystallography? Posted: 19 Feb 2017 04:32 AM PST Also, how can you deduce phase information for the structure factors of the native protein data set FP? Assuming you have a native protein data set (FP) and two different derivative data sets (FPH1 and FPH2). I was trying to use a Harker construction to understand these questions but still struggling [link] [comments]  |

| Posted: 18 Feb 2017 09:39 AM PST Since there's some neurological and psychological sexual dimorphism in humans I was wondering to what extent the differences are due to culture. I've only seen studies comparing male/female/intersex in western or westernised cultures using a european gender system. Are the differences in personality traits, aggression, types of intelligence, brain structure, hormones and such seen in the same way in other cultures? Do they vary based on sex alone or also gender? Is it too difficult to study due to the influence of western cultures? [link] [comments]  |

| Posted: 18 Feb 2017 06:33 PM PST This is something that has confused me for a while now. Is a 200HP car twice as powerful as a 100HP car. (All other variable taken out of course). Is it scalable? Can I say that a 200HP car twice as powerful, or is it scaled? [link] [comments]  |

| Posted: 18 Feb 2017 05:36 PM PST Taking it right now (few days) and not coughing so how is the expectorant supposed to work. How do they not cancel each other out as they are opposites? [link] [comments]  |
| Does a solar panel violate Ohm's law due to its non linear I-V curve? Posted: 18 Feb 2017 02:18 PM PST Ohm's law states that U=IR, but solar panels and triboelectric generators, for example, show a non-linear relationship, as found in the link http://myelectrical.com/Portals/0/SunBlogNuke/2/WindowsLiveWriter/PhotovoltaicPVElectricalCalculations_BD16/Image53.png Is it a semi-conductor thing, given that diodes have similarly non-linear IV curves? I have thought of parasitic effects, but I do not believe they'd be as significant. [link] [comments]  |
| Are organ transplants from close family less likely to be rejected? Posted: 18 Feb 2017 06:59 PM PST I'm wondering if being closely related (and as such more genetically similar) to an organ donor would have any effect on if an organ would be rejected. [link] [comments]  |
| Can you create a machine learning algorithm to create a computer virus? Posted: 18 Feb 2017 07:32 AM PST So I have seen a lot of machine learning videos, including This one about Mario, This one about discerning instruments, This one about language, and this series on evolution simulators. Then, I also saw this xkcd. It made me think about since there are so many ways to produce machine learning algorithms in so many disparate fields and to do so many things, could you have an xkcd style virus-farm and try to use machine learning to look for security holes? The MarI/O simulator found a glitch in Mario, on this video and timestamp so it might not be too far a jump to consider that a really advanced neural network might be able to evolve a way to hack computer systems? If so how would it work? Note: This is purely hypothetical. I just thought it would be an interesting idea. [link] [comments]  |
| What is the proper derivation of Wien's approximation? Posted: 18 Feb 2017 11:16 AM PST I haven't seen anywhere on the internet a proper derivation of the Wien approximation, all of them try to derive it from Planck's law. Anyone can give me a detailed derivation, preferable also showing the law as it appears in Planck's paper ( u(lambda,T)=T5f(lambdaT) )? [link] [comments]  |
| Why does drying seeds change their nutritional value so much? Posted: 17 Feb 2017 11:20 PM PST For example: Fresh Pumpkin seeds have 54g of Carbohydrate and 19g of Fat, but dried seeds have 11g of Carbohydrate and 49g of Fat. (Google) I would have thought drying means just removing water, and also that removing water would not cause this. Please explain. [link] [comments]  |
