| Posted: 05 Sep 2017 09:25 AM PDT The post from front page had me wondering. If you were to actually find a playing card on the floor every day, how long would it take to find all 52? Yes, day 1, you are sure not to find any duplicates, but as days pass, the likelihood of you finding a random card are decreased. By the time you reach the 30th card, there is a 22/52 chance of finding a new card. By the time you are looking for the last card, it is 1/52. I can't imagine this would be an easy task!

| Aside from Pu-238, what other sources of power could be used for deep space satellites? Posted: 06 Sep 2017 06:35 AM PDT I know Pu-238 was used by numerous satellites like Cassini and Voyager, but is there any other nuclear power source with a similarly long half-life? Po-210 would seem to be a possible substitute, but it's half-life is too short. [link] [comments]  |
| It is said the theoretical maximum sustainable wind speed in a hurricane is around 200mph. Why? Posted: 05 Sep 2017 02:01 PM PDT While there might be spikes above that, it is said that the theoretical maximum speed of wind, that a hurricane can keep up sustainably, is around 200mph. This is what Hurricane Irma is approaching towards. Why is that so? [link] [comments]  |

| Why can't quarks exist as separate individual particles? Posted: 05 Sep 2017 04:01 PM PDT Im reading a physics book and the author just wrote the above argument with no explanation/ reference to some research on the subject as a basis. As if this was a given. I demand an explanation! [link] [comments]  |
| How do scientists measure extreme temperatures? Posted: 06 Sep 2017 12:55 AM PDT E.g. the melting point of steel or near absolute zero. I'm pretty sure a regular thermometer wouldn't cut it. [link] [comments]  |
| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 06 Sep 2017 08:06 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology 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: 05 Sep 2017 03:31 PM PDT With the recent Hurricane Harvey hitting the United States in Texas, the American HMON model showed Harvey heading over Mexico, while the European model's prediction was very close to the actual path. Why is the American model so far behind? Article for reference: https://arstechnica.com/science/2017/09/at-times-during-harvey-the-european-model-outperformed-humans/ [link] [comments]  |
| How do all-purpose cleaners work? Posted: 05 Sep 2017 05:11 PM PDT I have a bottle here that lists several ingredients including: decyl glucoside, sodium citrate, glycerin, and a lot of natural oils. How do these ingredients actually clean a surface? [link] [comments]  |
| How does being struck by lightning and surviving affect the survivor's physiology? Posted: 05 Sep 2017 03:42 PM PDT I've heard several stories of people being struck by lightning and surviving. In some cases, the same person was struck more than once at a different time. How does a lightning strike affect the body of survivors? Does it have any long standing effects that can be seen years after? [link] [comments]  |
| How does a radar measure a rotational speed of a baseball? Posted: 05 Sep 2017 09:41 PM PDT
You can easily see these kinds of stats in baseball forums. [link] [comments]  |
| How do trees know what time of year it is for defoliation? Posted: 05 Sep 2017 03:46 PM PDT I always thought it was something like hibernation, or if they are on a schedule? Thanks for answering! [link] [comments]  |
| Are there tectonic plates on Mars? Posted: 05 Sep 2017 07:39 PM PDT Earth's mountains and volcanoes are formed by tectonic plate collisions (at least, that's my basic understanding of it). So, is this the case on Mars? Does Mars have earthquakes (or, maybe call them marsquakes)? What about the volcanoes on Mars? Are there any, and if so, what are they like? Are the igneous rocks formed by those volcanoes similar to those on Earth? Also, what about Mercury and Venus? What do we know about those planets? [link] [comments]  |
| How do rocket scientists know what velocity is needed to enter the orbit of bodies other than Earth? Posted: 05 Sep 2017 07:47 PM PDT I'm been bingeing "Space Race" stuff lately and I think I can comprehend how we calculated the velocity required to enter orbit above Earth. I don't understand how we made the calculations to have a spacecraft enter orbit over a body that humanity has not set foot on. What kinds of data were used to calculate velocities to enter orbit above bodies such as Jupiter. I thank you in advance for any responses. [link] [comments]  |
| How small could an aneutronic reactor be? Posted: 05 Sep 2017 08:24 PM PDT I'm interested in reality-grounded science-fiction power sources, and it was suggested to me that very small reactors could be make if we mastered aneutronic fusion. How small could an aneutronic fusion reactor be and remain safe for biological life to be around? How would the size affect the efficiency? Note: I'm not an idiot, but I'm no engineer or nuclear physicist. [link] [comments]  |

| How inaccurate are typically earthquake magnitude estimates? Posted: 05 Sep 2017 10:16 AM PDT Estimates of the magnitude of the earthquake created by the most recent North Korean nuclear test range from 5.6 to 6.4. That's a range of 0.8, corresponding to a factor 15 uncertainty in energy release. Is an uncertainty this big typical for an earthquake of this size? [link] [comments]  |

| Posted: 05 Sep 2017 04:39 PM PDT Curious. Suggestions: Go inverse? (Assuming it was an Antagonist, treat it with an agonist and vise versa - going with a Antagonist with this example) I'd imagine that it wouldn't actually neutralize the antagonist that is causing the effect and instead you would with a constant fluctuation receptor activity? (I'd imagine) Also, you couldn't find exact agonist to negate the effect - finding a similar agonist sure, but you will end up with maybe more side effects where the agonists and antagonists don't match. Clearing cycle? The brain has its own maintainence cells (Neuroglia) that do various things from providing homeostasis to removing cells and foreign substances. Pharmaceuticals that do antagonises/agonises receptors I would imagine wouldn't (?) detect as a threat because the pharmaceutical works. Does it? Is it not? Does it actually Are the special onset triggers for certain neuroglia? Would it even clear foreign receptor binders if specially triggered? etc. etc. Food/Exercise? Something just as simple as eating the right water/fat soluble foods or doing loads of cardio or is it more complex than that? To say a substance will cover everything is very ambiguous. Feel free (please) to use any other receptor examples or even solutions while explaining. I assumed serotonin receptors in my explanation. Thank you. Please, when you explain the answers please explain them in layman terms, I use all these terms when in fact I am just really dumb. Thanks a lot. [link] [comments]  |
