| Posted: 18 Apr 2018 08:12 PM PDT Are bird/whale (animals in general) songs learned or genetically programed? IOW, are animal songs the same in captivity as nature? My dad and I were talking about this and we didn't know. We heard (but after googling I couldn't find this) that there was a university test whereby chickens were raised for generations in captivity and never squawked seeing shapes (such as squares and triangles) fly over, but then fifteen generations later the researchers sent one hawk and all the chickens were frightened. This is a general question about genetically remembered fears or traits that aren't exactly taught. Edit: I wasn't sure which flair to put this under. I think it would be more appropriate for zoology (but that is not present); so, I put it under biology. I think this is accurate since I ultimately am asking about the biological questions relating to genetically implied actions. [link] [comments]  |
| Does rate of dissolution of salt change while a quantity of salt is being dissolved? Posted: 19 Apr 2018 07:07 AM PDT I have two buckets full of enough water that the amounts of salt I am attempting to dissolve will not saturate the solution. I want to dissolve a quantity of salt, X cups, in one bucket. In the other bucket I want to dissolve 2*X cups. Will these two quantities finish dissolving at the same time? Does the amount of salt already dissolved in the solution affect the rate of dissolution? [link] [comments]  |

| Does bees' honey concentrate or filter out toxins from the original flowers? Posted: 18 Apr 2018 02:54 PM PDT I was thinking of this recently when reading an article on the main page about NYC beekeepers. In a pollution-heavy area, where flowers might be exposed to toxins in the ground/water/air, can those toxins concentrate into honey? Or is pollen and/or honey somehow insulated from toxins by some mechanism? Since I imagine it will be asked, we can break them out into earthly/local contaminants (heavy metals in the soil, agricultural runoff, etc) and air pollution from cars/trucks/smog/etc. [link] [comments]  |
| Sending a rainbow into a prism? Posted: 19 Apr 2018 02:56 AM PDT If colored light rays were to send into a prism in the correct angles (Just the reverse of what happens to white light), would it produce actual white light? [link] [comments]  |
| How does voyager 1 not run out of fuel? Posted: 18 Apr 2018 08:06 PM PDT Sorry if this is a dumb question, but that thing is in space since 1977 if I'm not wrong. How has it not ran out of fuel? Or hit a meteor or something? [link] [comments]  |
| Are Fourier transforms something fundamental in our Universe? Posted: 19 Apr 2018 03:49 AM PDT So I was watching a Sixty Symbols video about bandwidth and Fourier transform and in some part of it, it is said that Δf x Δt ≈ 1, where Δf is the range of frequencies that can pass through the cable and Δt is the minimum pulse width that those frequencies can make(Fourier). So for example in an optical fiber cable you can't send very short pulses because the Fourier transform of that pulse would have frequencies components beyond the limit of the optical fiber. My question is: That doesn't imply that the Fourier transform(and its sinusoids components) are not only a mathematical tool but a fundamental part of our universe? I mean, shouldn't the minimum pulse width be determined only by the wavelength of the frequency carrying the signal? [link] [comments]  |

| How do LIGO results infer distance/size etc of source? Posted: 19 Apr 2018 01:25 AM PDT I have some questions about how LIGO works... I understand the basics and how it works by basically detecting very small changes in a laser beams path. Thats fine I get that that is an indicator of gravitational waves. So..

| Posted: 18 Apr 2018 11:05 PM PDT I am not asking for medical advice. I am struggling to find out why this time line is stated on the pamphlet, and the label my pharmacist(s) put on the packaging. Basic searching (as far as I have delved) only results in the actual medicine and its uses, not why you shouldn't take "indigestion remedies" within in this period. I also cannot find what types of indigestion remedies they are saying to avoid. I respect this isn't ELI5, but I'd appreciate some clarification as to why, that a layman can understand. If not, I'm happy to read papers relating to this to try and figure my own way around, slowly. Thank you. Oh, they are gastro-resistant (enteric, if you prefer) capsules. [link] [comments]  |

| How (if they do at all) do orb-weaver spiders establish territories? Posted: 18 Apr 2018 09:07 PM PDT There's lots of spiders near my house. How do they determine which one gets to build its web in the sunny spot near the outside faucet (which is like an all-you-can-eat insect buffet), and which ones have to go up to the third floor (where there never seems to be as many insects caught in the webs). Strangely the spiders on the ground level, with the prime insect supply, seem to be smaller than the vast monsters on the third floor. [link] [comments]  |
| Where exactly does the LHC get protons? Posted: 18 Apr 2018 12:35 PM PDT I want to a talk recently that stated that the LHC accelerates protons to relativistic speeds, and I was wondering where they get the protons? I was under the assumption that they create a positive hydrogen ion, leaving just the proton - is this correct? And if so, how is it done? Thanks! [link] [comments]  |
| What's The Deal With ITER's Funding & Timeline? Posted: 18 Apr 2018 06:29 PM PDT It's supposed to take until 2025 to be assembled and then another 10 years for the full scale experiments. It's estimated to cost 20 billion Euros. This seems like a paltry sum for Europe, China, or the USA, let alone a collaboration between them and Japan, India, Russia, etc. so it seems like participants could fairly easily pony up additional funding. Does building it just take that long due to the nature of the project or is it a matter of funding such that doubling the funding move the 2035 date up to the 2020s? [link] [comments]  |
