| How do non buoyant things wash ashore? Posted: 15 Jul 2019 05:14 AM PDT Just saw a post about a huge megalodon tooth that was found off the coast of North Carolina. How does something like that wash ashore? Does it ever reach the ocean floor, or has it been traveling around the world via ocean currents for millions of years until it finally reaches land? Or did it reach the shore a long time ago and was only recently exposed?? [link] [comments]  |

| How do doctors figure out if an illness/symptoms are psychosomatic? Posted: 15 Jul 2019 01:40 AM PDT I have been lurking on r/medicine a lot lately and the general consensus over there seems to be conditions like fibromyalgia and CFS are psychosomatic. Articles I've read can't seem to agree if this is the case. So it seems like it would be up to the individual doctor to make a decision on a case by case basis. How do doctors know this? Is it a diagnosis of exclusion? Is there any way to prove or disprove that a patient is having psychosomatic symptoms, or is it always just a guess? If someone is getting mental health treatment already, does this rule out symptoms being psychosomatic? Especially if the treating mental health professional believes the symptoms are organic in origin? If the "physical" doctors and "mental" doctors disagree on the origin of symptoms, how do they come to a consensus? Thank you!! It just seems like something like this would be really hard to confirm/diagnose because there is no test or diagnostic criteria for it. So I'm really curious how it is actually decided.

| What are the differences in the processes that create Neutron Stars, Pulsars, and Magnetars? Posted: 15 Jul 2019 01:21 AM PDT I am able to find numerous posts and articles explaining how they're different, but I'm not able to find anything explaining why they're different. What are the differences in the creation process of each that causes some neutron stars to be just that, some to become pulsars, and some to become magnetars? [link] [comments]  |
| Regulating Indoor Temperatures Between Hot & Cool Air Flow: When is it Optimal to Shut the Windows? Posted: 14 Jul 2019 09:47 PM PDT There is a debate in my house about when to close the windows to keep the house cool. My dad insists on waiting until the air coming inside is noticeably warmer than the air in the house. I contend that by the time we've physically detected this, it's too late and most of the cool air has been displaced. The coolest temperatures are during the night and early morning, so by mid-morning much of the cool air will have leeched away through process of equalization with the warming exterior air. I experimented by closing the windows mid-morning rather than late morning, and found that the house stayed several degrees cooler for the entirety of the day. But he believes that I am shutting the home up prematurely and merely preventing us from reaping the full benefits of the cooler morning air. I have searched google, and although several sources say that you should close the windows when it's hotter outside, nothing I've found speaks to the optimal timing, or how best to maximize and preserve cooler interior temperatures. We all know heat rises, but what about horizontal drift? Do we wait until it's noticeably hotter outside, or do we shut the house up early? [link] [comments]  |
| When a guy cums does it come from both testicles simultaneously? Posted: 14 Jul 2019 03:11 PM PDT Or just one per ejaculation and they alternate? Or does one operate for so many years then retires? What happens if a testicle gets cancer and must be removed, how is ejaculation affected? [link] [comments]  |
| Do spiders only use webs they make and are those webs “fingerprinted”? Posted: 14 Jul 2019 06:10 PM PDT Do spiders have unique webs with pheromones that are specific to the spider or any chemical signatures that could distinguish the webs? I'm looking at some spiders right now and wondering if they take over abandoned webs and also if their webs have any marker genetic material or pheromones . [link] [comments]  |

| Posted: 14 Jul 2019 09:44 PM PDT When did the convection currents and the subduction begin? I've tried to google this, but there doesn't seem to be a widely accepted theory on the matter, and the latest articles were published years ago. This is my first post on this sub, so I'm sorry if I failed to follow any format or rule. Thank you in advance! :) [link] [comments]  |

| Why were the first particles accelerators in a "zig zag" shape? Posted: 14 Jul 2019 12:29 PM PDT I recently visited the science museum in London and a particles accelerator was in display. I would think that a circular shape is often used (for example in synchrotrons or the LHC) because it is easier to accelerate the particles within that shape, using the Lorentz Forces (I am not very knowledgable in physics). I saw some linear ones also but the principle was the same, minus the magnetic field if I recall correctly. I wonder why the first ones were in zig zag? I believe that calculating the trajectories and the positions of the condensators is feasible, but a pain in the ass. So I wonder why they did not choose some "easier shape"? Of course Lorentz, Rutherford and the guys working on that were way smarter and knowledgable than me so ... Why this shape? Also, if I understand correctly if for example an electron is slowed down (or a proton) a photon will be emitted, so this kind of shape would be a problem because of the various turns, no? How did they overcome that? [link] [comments]  |
