| How were sufficiently coherent light sources generated for optics experiments before lasers? Posted: 09 Oct 2018 12:48 PM PDT All the optics and photonics lab work I did as an undergrad a decade ago used a laser as the source due to its coherence. I still don't understand how the famous optics experiments (thin slit interferences, interferometers...) that predated the laser were achieved without that advantage. [link] [comments]  |
| Why can't the water being stored at Fukushima be reused for cooling? Posted: 10 Oct 2018 05:15 AM PDT I'm sure it has been asked before but I cannot find the answer. Why can't the massive amounts of radioactive water being stored at Fukushima be reused to cool what is left of the reactors? [link] [comments]  |
| How does the nuclear power source work on the Voyager spacecraft? Posted: 10 Oct 2018 03:22 AM PDT I understand how normal steam turbine nuclear plants work. It's perceivable that Voyager uses a similar system but a bit impractical.. If anyone knows how Voyager makes its power I'd be greatly appreciated. Thanks [link] [comments]  |
| Posted: 10 Oct 2018 04:00 AM PDT It's early October and a new crop of students are making their way through the challenges of their first semester at college or university. Academic deadlines are starting to loom for everyone, and some students are about to write their first midterms. In our research, we've noticed across several samples of undergraduates that problems like depressive symptoms start to get worse on average over the course of the first year of university. A paper we published earlier this year showed this effect specifically for students who experienced relatively higher levels of academic stress. https://www.ncbi.nlm.nih.gov/pubmed/29470761 In our research we're hoping to get a better idea of what we (universities, parents, and students) can do to ease the transition to university and help students set themselves up for success across their university careers. Social relationships, academic habits, working while studying, substance use and other lifestyle behaviours, and financial stress are all pieces of the puzzle that we're examining in our labs. We'll be here from 12pm to 2pm Eastern (16-18 UT) and are looking forward to your questions and comments! [link] [comments]  |
| What are neutral mesons made of? Posted: 09 Oct 2018 09:21 AM PDT I was reading about the different types of mesons on Wikipedia and learned that, while most of them seem intuitive - a bound state of a quark and an antiquark, there are some (such as the neutral pi, rho and omega mesons) whose composition is "(Downantidown - upantiup) / square root of two". What does this mean? Are they oscillating between flavors? What's the difference between the neutral pi and rho mesons if they both have this same weird composition? It gets even weirder when I see there is no "normal" bound state of up/antiup and down/antidown yet there exist mesons made up of charm/anticharm, strange/antistrange and bottom/antibottom.

| If we had a mass of Neutrons in a vaccum would they turn into Hydrogen Gas? Posted: 10 Oct 2018 05:14 AM PDT Hello, So I know that a Neutron is composed of Down Down Up Quarks. I also know from reading that a W Boson leaves one of the Quarks it becomes a Up Up Down which is a Proton as well as ejecting an electron and an Anti-neutrino. I also know that the half life of a Neutron outside the nucleus is about 14 mins so it decays quite quickly My question is if we had a mass of Netrons that all decayed like this not being near other matter (and therefore not able to enter the nucleus of that matter)? Would it not form a cloud of Hydrogen Gas as it would leave behind Protons and electrons? [link] [comments]  |

| When a person urinates, why doesn't their bladder create a vacuum? Or does it? Posted: 09 Oct 2018 06:38 PM PDT I just realized, how can urine flow and be replenished without us feeling discomfort of the bladder shrinking. How does the bladder not create a vacuum after all of the urine is excreted? Does air somehow fill the space the urine had left or are there muscles that allow the bladder to contract and decrease the space that is now empty? [link] [comments]  |
| Question why is one side of a person different to the other? Posted: 10 Oct 2018 03:06 AM PDT So I've recently been taking notice that probably down the middle of a human being you can see all sorts of minor defects most common is one eye socket larger then the other. Also fingers being larger then the ones on the other hand. What is the science? [link] [comments]  |
| How to determine if a large set of numbers was randomly generated? Posted: 09 Oct 2018 05:02 PM PDT Lets say I am trying to determine if my D20 is balanced by tracking the outcomes. I have a sample size of 800 rolls which I would think would be sufficient for this analysis. I know that there are different statistical tests that can be performed to determine if the data set is truly random but I don't understand statistics enough to perform or understand the outcome of any of the tests. I have my samples recorded in excel and if there is a way to do it in there that would be even more helpful but I am open to any suggestions. If my sample size isn't big enough I can always add to it without a problem. [link] [comments]  |

| Can animals be afraid of an item which represents a predator they have no point of reference for? Posted: 09 Oct 2018 04:46 PM PDT So a while ago there was this trend of people scaring their cats with cucumbers. Some people stated it could've been because they look like snakes. This sparked a discussion between my friend and I. A current domestic cat has never seen a snake, nor has it had any reasons to be afraid of something with a similar look. Is it possible that this knowledge is hereditary? In other words, can an animal be afraid of an item because it represents a dangerous animal which it has never seen or met? [link] [comments]  |

| How do warmer falls effect bird migration? Posted: 09 Oct 2018 06:34 PM PDT I live in the north east United States, and it was nearly 80° today, which is the warmest I've experienced in October. Does this confuse birds and other animals as far as when they should migrate? Some days have been warm, but others are dropping below 50° [link] [comments]  |
| Is there an evolutionary explanation to why some people don't have wisdom teeth? Posted: 09 Oct 2018 11:06 AM PDT In the distant future should we expect people with wisdom teeth to be as rare as people without them today? [link] [comments]  |
| How is surface tension related to droplet formation? Posted: 09 Oct 2018 01:15 PM PDT Say you're trying to form a drop of water by letting it out of a small tube. Using the same tube, after adding soap to the water, will the drops formed in this process be bigger or smaller compared to pure water drops? [link] [comments]  |
| If you had a fossil of one of your ancient ancestors, could you tell that you were related? Posted: 09 Oct 2018 12:30 PM PDT Let's say I have a fossilized bone from early homo-erectus. Is there a way I could tell if I am it's descendant? If so, how? If not, why? [link] [comments]  |
| What makes us think we can directly detect Dark Matter? Posted: 09 Oct 2018 09:20 AM PDT There are in-progress experiments to directly observe Dark Matter (or, specifically, WIMPs) via scattering off atomic nuclei within large (and very sensitive) detector apparatus What makes us think that WIMPs will interact with nuclei in this way? Is it not possible that WIMPs interact via gravity only - and hence would not be expected to trigger the detector? [link] [comments]  |
