- The Tsar Bomba had a yield of 50 megatons. According to Wikipedia "the bomb would have had a yield in excess of 100 megatons if it had included a uranium-238 tamper". Why does a U-238 tamper increase the yield as opposed to other materials or no tamper at all?

| Posted: 26 Mar 2019 05:35 PM PDT I'm thinking in terms of people who grew up with not a lot of food. As adults when they eat they might tend to scarf it down or hoard it for later. Even though they have plenty to eat now, they are still psychologically effected from not having much when they were growing up. Would behaviorisms like that occur from sleep deprivation?

| Posted: 27 Mar 2019 02:09 AM PDT We just learnt about Rayleigh, Mie and Fraunhofer and neither our Prof nor his contacts could sufficiently answer at which particle size the particle becomes too large for Fraunhofer diffraction and instead casts a shadow, like a regular ball for example.

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 27 Mar 2019 08:12 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]  |
| What is the explosion speed of gasoline? Posted: 27 Mar 2019 07:12 AM PDT I was looking this up because I was wondering how fast someone would have to run to out run a gas fireball. But I couldn't find it anywhere. [link] [comments]  |
| How does blending fruit/veg change nutrient content and uptake by the body? Posted: 27 Mar 2019 12:50 AM PDT I have read that blending can change the speed with which your body absorbs sugars, making blood sugar spike rather than slowly releasing sugar (when you eat the food). But does blending change the vitamin or micronutrient contents of the food? E.g. a smoothie of spinach, blueberries, strawberries, apple juice. [link] [comments]  |
| Do animals experience the same side effects of "neutering" that humans do? Posted: 26 Mar 2019 04:13 PM PDT If a human gets his/her testes/ovaries removed, they go through a host of symptoms. Hot flashes, dry skin, vaginal dryness, tiredness, decreased muscle mass, etc, due to the lack of hormone generation. Do animals, have similar symptoms when they get neutered? (By the way I'm mainly talking about cats and dogs in comparison to humans, but I'm open to other comparisons too.) Neutering also doesn't seem to have any negative affect on the appearance of an animal (Like menopause in women). And it has a positive affect on their temperament. Neutering seems to have net positive consequences for animals, but more mixed results for humans. Is this correct or am I missing some information? A positive side effect neutered humans and animals share though, is increased longevity. [link] [comments]  |

| How do Robin's, or any other bird, find worms in the soil? Do they use sight? Posted: 26 Mar 2019 03:05 PM PDT I live in Wisconsin in a quiet neighborhood so I have a lot of different birds in my yard most of the year. I know I could ask Google, but Reddit is way more informational, and way more hilarious. Thank you. [link] [comments]  |
| Posted: 27 Mar 2019 03:21 AM PDT For example, would a 10% bodyfat 120kg male bodybuilder require the same dose as a 50% bodyfat 120kg sedentary man? [link] [comments]  |
| How does loaf balancing of electric grid work? Posted: 27 Mar 2019 02:58 AM PDT As I understand, the electric grid needs to have exactly the amount of electricity necessary to accommodate a given number of users. How can an electric grid adjust its power every time a user is connected/disconnected? This adjustment seems to be needed instantaneously, but I suppose it takes some time to increase or reduce the power. [link] [comments]  |
| How do viruses that code for lysozymes not end up lysing their host cell too soon? Posted: 26 Mar 2019 12:36 PM PDT My biology teacher wasn't able to answer this question so I turned to you guys. If a virus is non-enveloped I was told that they would escape their host cell during the final step of the lytic cycle. Lysozymes would Lyse the host and all the virions inside would escape to infect more cells. My question was, if the lysozymes were coded for in the virions' nucleic acid, wouldn't they be produced at the same time as the other viral components? And if this was the case wouldn't the virus shoot itself in the foot so to speak by lysing it's host before enough virions were produced? Thanks in advance for reading and I hope somebody can shed some light on this topic for me. [link] [comments]  |
| Posted: 26 Mar 2019 05:54 PM PDT People like to mention that mushrooms are closer related to animals than to plants. I can't think of a quick or easy way to look this up (having to go into each kingdom, etc.) so was hoping someone here happened to know. So what's the closest organism to an animal that still fruits?

| What's happening inside the computer when it "hangs" and won't respond? Posted: 26 Mar 2019 02:08 PM PDT I have this old laptop that I've been trying to coax into doing basic tasks but it seems to have trouble even maximizing a window without stopping to think about it for a good 30 seconds. So what's going on inside the computer when it freezes up trying to do a simple task? Why does it freeze up in the first place? [link] [comments]  |
| Where Does The Space From Deleting Files Come From? Posted: 26 Mar 2019 05:53 PM PDT When I delete/uninstall a file (say, a 30 GB video game), I get an extra 30 GB on my PC. BUT, aren't the files just sent to the Recycle Bin? I can retrieve and reinstall them whenever I want to, so they're obviously still stored on my PC. Where does this extra space come from?

| Posted: 26 Mar 2019 11:59 AM PDT I know we're no longer exporting recyclable waste to the extent we used to: https://www.nytimes.com/2018/05/29/climate/recycling-landfills-plastic-papers.html I also imagine there's a huge variation between the contents of people's single stream recycling (oil coated pizza boxes going in recycling at one person's house, but the trash at another's) from household to household. We used to add glass to our recycling bins, but were told to stop and then agreed to a $5 surcharge for a separate glass only basket that we can use to recycle just glass. I loved (I know this is weird) the painful calendar and trash room my Japanese condominium had where I could recycle batteries separate from clear glass separate from colored glass separate from cardboard, etc., etc. In the interest of actually recycling in a meaningful way, I'd rather dial back what I throw in my recycling bin than err on the side of throwing in a bunch of stuff that may make recycling it less practical. Anyone have any good, clear, recent info on this they can share? It's something I'd like to better understand. [link] [comments]  |
| What determines how large (or small) the flame on the wick of a lit candle becomes? Posted: 26 Mar 2019 09:46 PM PDT While watching a new candle burn on a desk across from me, I noticed that its flame reaches higher than the previous candle I had. I thought it might be the length of the exposed wick, but that's about the same as the other one. I'm also thinking about how bunsen burners have higher flames when you burn more gas, but I'm not quite sure how that connects here (if at all) since flame height was still different even when the candles were brand new.

| Can exist a 0-dimension manifold? Posted: 26 Mar 2019 04:45 PM PDT I start with an example: SL(1,R) (it should be valid also in C and in H) in theory is a 0-dimension manifold (it is a manifold with dimension 12 - 1 = 0) (SL(1,R) are the matrix with determinant equal to 1, if it is 1x1 then is the only number 1) The problem is, can a manifold have dimension equal to zero? (Can a Manifold being a point?) Or the dimension should be at least one? [link] [comments]  |
| Posted: 27 Mar 2019 01:05 AM PDT I recently watched Triple Frontier and in it they need to lift 6000 pounds above the andes mountains. The helicopter they use was told to be able to lift 9000 under 2000 ft. They ended up going past the 2000 limit while flying and the helicopter ended up crashing. Is this just hollywood or do helicopters lose the amount of weight they can carry the higher they go? And if so why? (Sorry if flair is wrong I don't know if this would be engineering or physics) [link] [comments]  |
