How stable are lagrangian points really? Posted: 19 Jul 2019 04:54 AM PDT Lagrangian points are supposed to be points, where gravitational and centrifugal forces are in equilibrium. And spacecrafts and -stations are supposed to be easy to build and keep there. However my understanding is that an equilibrium like this is only possible at one exact spot. Let's say we put a space-station at a lagrangian point. How much would the shifting center of mass due to spacecraft docking/undocking and people moving around affect the stability of the station at a lagrangian point? If all people and equipment would move to one side of the station, would it "fall off" the lagrangian point? submitted by /u/PancakeZombie [link] [comments]

When you make a lemon battery or potato battery and the use all the energy, will it be less nutritional for you if you eat it after? Posted: 18 Jul 2019 06:31 PM PDT I truly don't even know what flairs to give this because I don't know if this is and electrical engineering thing or maybe a biochemistry related question or what, so I'm sorry for that. ​ I've been trying to google the answer to this, and so far I think I understand that when you do that elementary school science project where you make a battery to power a really small light bulb with a lemon or potato or whatever, it's using a chemical reaction between copper, zinc, and the electrolytes within the juices of the produce you're using that creates electricity (I really hope that's at least somewhat correct or I'll look even more silly than I already do). I'm wondering if, after you do that, is that potential energy that your body could use from eating whatever it is using gone, or is it using an entirely different kind of energy. ​ Thanks in advance. I know it sounds like a very silly question. submitted by /u/kettlebear [link] [comments]

Do one's preferences for art (your artistic taste) have a strong connection to your personality? Posted: 18 Jul 2019 10:23 PM PDT So I was wondering if the way one has developed their tastes for art be it through visual or auditory stimuli, (say your liking or disliking for a particular UI/ typography design or your liking/dislike for a particular kind of music to state random examples) can have any relevant connection to your personality (say the big 5 traits). By relevant, I mean if there's some definitive observations rather than just so-so correlations from some of the research papers. (As I've come across a lot of that). submitted by /u/YippiKiYayMoFo [link] [comments]

How much adrenaline is released by our adrenal glands in an "adrenaline rush", compared to the dose administered in an Epi-Pen? Posted: 17 Jul 2019 06:02 PM PDT I am interested in comparing (a) the ability of our adrenal glands to release and adrenaline/epinephrine bolus when needed, to (b) the amount of adrenaline in an Epi-Pen (which is 0.3 mg for an adult). Beyond this, I am trying to figure out why our adrenal glands do not produce enough adrenaline during an anaphylactic episode. Is it because (a) adrenal glands cannot produce enough adrenaline, (b) their adrenaline stores have been depleted, (c) for some reason, they are not stimulated to release adrenaline during anaphylaxis, or (d) they release too much noradrenaline along with adrenaline. submitted by /u/Erasmus_B_Draggin [link] [comments]

AskScience AMA Series: I study the mutualistic relationship between alligators and wading birds in the Everglades. AMA! Posted: 18 Jul 2019 04:00 AM PDT Hi everyone! My name is Wray Gabel, I'm a Masters student at the University of Florida advised by Dr. Peter Frederick. A little about my research--my thesis explores the mutualistic relationship between nesting wading birds and the American Alligator. Basically, wading birds get protection from nest predators (like racoons) and alligators get food from discarded nestlings. I'm looking to 1) better understand what alligators might be getting out of the deal and 2) how this mutualism might be changing wading bird colony location preferences when alligators are not around. I conducted my field work for part 1) in the Everglades and used existing wading bird colony location data from North and South Carolina for part 2). A little about me--I actually grew up wanting to become a paleontologist, which was really what ignited my passion for field work and biology, but ultimately I found currently existing animals to be more fun than rocks. I got my undergrad degree in Biology from Skidmore College, and after graduating I worked with seabirds in Japan (Hokkaido University), wading birds/waterbirds in San Francisco (San Francisco Bay Bird Observatory), and seabirds in Maine (Audubon's Project Puffin). I'm mainly interested in the conservation of coastal and wetland ecosystems and hope to do something with wading bird, waterbird, and/or seabird monitoring in my future career as a wildlife biologist. I also minored in Studio Art while at Skidmore and plan to create an illustrated version of my thesis, and I'll be attending an Art-Science residency this fall! I've always been passionate about bridging the (artificial) divide between the two disciplines. In what little spare time I have I enjoy hiking, traveling, playing video games/board games/rpgs, listening to/collecting music, and doing crossword puzzles! I am doing this as part of an AMA series with the UF/IFAS Department of Wildlife Ecology and Conservation. I'll be on at noon (ET, 16 UT), AMA! submitted by /u/AskScienceModerator [link] [comments]

Do we have any concepts for the psychological differences between a human raised to learn language and a human raised without language? If so, what are they? Posted: 18 Jul 2019 12:05 AM PDT I apologize in advance if this question has been asked before. Modern day life is a bit hard to imagine without language. We read and talk with one another on a daily basis, and social interaction has become pretty deeply rooted in our psyche. That said, I'd like to pose a situation that removes language from a human's life, yet keeps social interaction. What sorts of behaviors would be exhibited by a human who does not learn a human language, but who does have interaction with other humans? Do we have any way of knowing? submitted by /u/Some-Weeb0874 [link] [comments]

If we don’t observe good dental hygiene we tend to lose our teeth. How did early man cope without toothbrushes, toothpaste, floss, etc? Posted: 17 Jul 2019 05:23 PM PDT How did early man cope without all the things we associate with good dental hygiene today? Did they continually lose their teeth and just deal with it? Or did they also observe rudimentary dental hygiene practices to slow tooth loss? Also, isn't tooth loss due to decay a kind of evolutionary flaw? submitted by /u/compostmentis [link] [comments]

Where can you find a source of true unpolarized light in the universe? Posted: 17 Jul 2019 04:38 PM PDT In our tiny lightbulbs, the emitted light either passes through air or glass, both dielectrics, and in gigantic stars, the light from the core passes through thick layers of gas, and then through the atmosphere of the Earth to reach our eyes. I cannot think of a situation where you find true unpolarized light in the universe. The best I can come up with is in maybe an ideal vacuum chamber where you then have something emit blackbody radiation. submitted by /u/_Sunny-- [link] [comments]

[Physics/Computing] Why can't we make silicon transistors smaller than 10 nm? Posted: 17 Jul 2019 01:30 PM PDT I don't entirely remember why but I think it was due to some sort of electron leakage, where something related to quantum physics took effect and the electrons would start teleporting from one side of the gate to the other side without the gate opening. If possible could you include a source supporting your answer submitted by /u/MexiAxel [link] [comments]

In a void, where does the energy of the sound goes ? Posted: 17 Jul 2019 10:19 AM PDT From what I understand, sound is produced by a pressure difference between 2 mediums, and propagates through matter (and therefore, not in a void). Now, I imagine since sound displaces matter less and less as it travels, it has some kind of energy dissipating progressively, right ? What happens to that initial energy when I try to produce sound in a void ? Does it just not exist at any point, or does it diffuse in its source instead of escaping it ? Also, what happens when a sound wave reaches a void ? Is it "reflected" in its original medium or does the matter right next to this void gets displaced farther/longer before coming back to its initial position (or maybe it is projected in the void instead ?) ?

Why Coriolis effect also affects East/West movement?

Can a woman get pregnant from two different men at the same time? Posted: 17 Jul 2019 07:45 AM PDT For example, say she has no protection and two men finish inside of her at roughly the same time.

When do people use Planck units? Posted: 16 Jul 2019 06:11 PM PDT I never really came across this topic. In high school, I would mostly still use The Law of Universal Gravitation, Colulomb's Law etc., so I never really knew about this at all, and what purpose do they serve (apparently it is to communicate with potential aliens under standardised equations?).

Why don't we see eclipses of external stars? Posted: 16 Jul 2019 03:18 PM PDT The question is pretty much the title. Why don't we see a constantly changing night sky with stars popping in and out of our view through let's say star bound planets crossing our path of vision? Shouldn't there be a significant amount of stellar eclipses happening all the time, visible to the naked eye?

Is it true that our body tends to store excess sugar we consume, but slough off excess vitamins in our urine? If so, why is this? Posted: 16 Jul 2019 11:23 AM PDT I feel like I've seen assertions to this effect here and there. I'm not sure why it would be true, though. I would think the body would either store excesses of both, or slough off excesses of both. But why would it do different things with the two different substances?

Apollo: How did the Lunar Module measure its speed? Posted: 16 Jul 2019 02:12 PM PDT Hi, this is my first post on Reddit- I tried Googling this question to no avail, so it's convinced me to finally get round to making an account! ​ I'm a 2nd year astrophysics undergrad so of course I've been lapping up all the Apollo 11 anniversary TV, but one thing has me stumped: ​ There was a moment during each of the Apollo landings at which both the astronauts and mission control switched to moon-reference coordinates. How did the spacecrafts actually keep track of their position from this point onward (and therefore their speed, altitude etc.)? Did the on-board computer actually have some way of actually "seeing" their position relevant to landmarks or is it something more sophisticated than this? ​ Thanks in advance! submitted by /u/lad_astro [link] [comments]

How do we "know" Sedna's orbit is so eccentric? Posted: 16 Jul 2019 10:49 AM PDT So while looking up the Oort Cloud for reasons, I remembered Sedna. Specifically because the sources included Sedna being theoretically right at the edge or within the inner reaches of the Oort Cloud. Since Sedna's orbit is so long, and we have ways to estimate how long a "year" is, that got me thinking: How do we know it is so eccentric, since we couldn't have had much of a chance to observe Sedna. submitted by /u/CrazyCoKids [link] [comments]

Posted: 16 Jul 2019 10:57 AM PDT I have a list of coördinates, the legend says that these are longitude and latitude, but when i try to use them it seems that they're not in the convention of how longitude and latitude should look like. Below is an example of such a coördinate from the list: Latitude: +511015,0 Longitude: +045801,7 -> These don't follow that convention and it seems that they're useless in google maps. For example, when I look-up coördinates on google maps I get them in the following format (Decimal Degrees) Example: 50.836666, 4.334930 Is this some kind of different system, and if yes, is there a way to convert the above ones into the DD notation? PS: It would also help if someone can point out the scientific name for that first type of coördinates. Latitude: +511015,0 Longitude: +045801,7 submitted by /u/aFluxxOnline [link] [comments]

What are does gravity being discovered as a wave mean for the current model of particle physics? Posted: 16 Jul 2019 12:10 PM PDT Hello Reddit, I saw and heard many times on the internet about LIGO detecting gravitational waves from two black holes. I learned in school about particle physics and force mediating particles(?) like how bosons are for the strong force, and how gravitons are for the gravitational force. Now that we know gravity is a wave, what does that mean gravitons or has the current scientific model for particle physics been altered because of this discovery? Thanks ​ PS - I also don't understand what gravity being a wave means. Is it similar to how light is a particle and a wave? And if so could their potentially be a constant speed of gravity like how there is a constant speed of light? submitted by /u/IHaveQuestions_42069 [link] [comments]

Is it always better to use a higher concentration of solvent for cleaning? Posted: 16 Jul 2019 07:47 AM PDT Hello r/askscience! ​ My question is, is it always better to use a higher concentration of cleaning solution? I realize this is a broad question but let me provide an example and hopefully flesh out what I'm asking. ​ Dish detergent. One school of thought I have encountered is to use as little water as possible, it's all about concentration. Try to get a "slurry" high in soap to cut through the grease. Another school of thought would be that you want enough cleaning solution dissolved in enough water. So to compare the two groups, they could use the same about of soap, but one with much more water. I was an amateur chemistry student, but I feel like you want there to be a lot of water as well as solvent so that there is a lot of water for your solvated grease/soap mixture to dissolve into without the concentration of the mixture becoming to high in the water. If there is too little water, I feel like you quickly run into a situation where there is a high concentration of grease on the pan, and a high concentration of grease/soap in the water, and now there is not much of a gradient, and the grease is not going to want to dissolve. Like, isn't there some equilibrium stuff going on here? Like, you wouldn't use pure soap, would you? Or maybe you would if it was actually cost effective... So it it always better to clean something using a higher concentration of your cleaner, or are there lower concentrations that are more optimal? Thank you. submitted by /u/Remnes [link] [comments]

Why was Deinonychus so pivotal to our current understanding of dinosaurs? Posted: 16 Jul 2019 10:22 AM PDT After all, Deinonychus was hardly the first "bird-like" dinosaur to be discovered and described. Many such dinosaurs were even given names alluding either to an active lifestyle or a relationship to birds (Velociraptor and Ornithomimus, for example.) So why did these views only become established fact after the discovery of Deinonychus? submitted by /u/redtail303 [link] [comments]
