| Would a superconductor pass through a walk through metal detector without being detected? Posted: 05 Jan 2017 05:52 PM PST As walk through metal detectors rely on metal disturbing a magnetic field, and superconductors through the Meissner effect eject magnetic fields, would a walk through metal detector (like at airport security) detect a superconducting superconductor?

| Are there simple studies proving or disproving the effectiveness of SSRI antidepressants? Posted: 05 Jan 2017 07:18 PM PST Sorry if this is the wrong place to ask but I've been searching for days and am getting desperate. I have found hundreds of meta-analyses on everything depression related, but does anyone have actual studies in which patients are given SSRIs and the improvement is measured? I have only found one of these using fluoxetine, despite scouring many databases and references of so many analyses and articles. Thanks for any help! [link] [comments]  |
| Has googles "GO" AI figured out a way to solve NP problems? Posted: 06 Jan 2017 06:30 AM PST I am am rather interested to know how the AI works. if it is truly unbeatable doesn't that mean Its effectively solving an NP problem in polynomial time?

| Is there an intrinsic property of smaller numbers that makes them more useful? Posted: 06 Jan 2017 01:05 AM PST Disclaimer: I know nothing about high level math and the entire premise of my question could very likely be flawed. Out of all the numbers ever used in mathematical proofs, smaller numbers occur much more often than astronomically large numbers. For example, numbers between 1 and 10 are used far more frequently than numbers larger than grahams number. I'd be willing to bet that there's some sort of exponential correlation between the value of a number and the frequency with which it has been used in a proof. My question is this: is the reason for this that there is a property of smaller numbers that makes them more "useful"? Or is this simply a byproduct of human brains not being complex enough to find more use in larger numbers? [link] [comments]  |

| Does picking a fruit or vegetable before ripening, change the nutritional elements? Posted: 05 Jan 2017 07:05 AM PST Does picking a fruit or vegetable before ripening, change the nutritional elements found in that fruit or vegetable? For example does the amount of lycopene change if you pick a tomato while it's green and let it ripen on the window sill vs ripening on the vine? [link] [comments]  |
| Posted: 05 Jan 2017 09:25 AM PST The results of it are obvious enough, but all I've been able to find is relatively surface-level stuff. People went into their roles, lost touch with reality, and temporarily completely changed their identity and personality. But what is the psychological process behind this phenomenon, and what does it relate to? I was also thinking of other contexts and how weird of roles people could adjust to. The David Rosehan experiments where normal, healthy people were sent to a psychiatric hospital and told to act normal and the doctors failed to notice. If someone were to be in a modified situation, and for longer, then could they possibly develop symptoms of the mental illnesses they were treated like they had? Not just the confirmation bias the doctors were experiencing, actual positive and negative symptoms. Could straight men temporarily become homosexual? Going even farther, and stretching what is rational a little bit, could we even adapt to the "roles" of other species? Think of feral children, who were raised by animals and acted exactly like them. Of course, that was all they knew, so it's different, but I really don't see adults adapting to be too much of a stretch. Those in the Stanford Prisoner Experiment adapted in 36 hours and lost contact with reality. Lastly, and this is just plain stupid, could we adapt to made-up roles? Fictional species and the like. Kind of like somataform disorders, made-up symptoms physically manifesting. [link] [comments]  |
| What causes the Congo River, the deepest river in the world, to be so deep? Posted: 05 Jan 2017 08:53 AM PST It's over 750 feet, how did it become so deep? And why aren't other rivers so deep? [link] [comments]  |
| Why does adding an iron core to a coil increase the flux density? Posted: 05 Jan 2017 08:40 AM PST So the current in the coil generates a magnetic field. Why does adding an iron core to the centre increase the flux density? I know it's something to do with the generated magnetic field reinforcing the domains that reinforce the field, and shrinking those that oppose it. But I don't exactly know what that means. What is a domain? [link] [comments]  |

| How do scientists calculate the necessary fuel to shoot a rocket (with astronauts) into space? Posted: 05 Jan 2017 09:17 AM PST If you could go into detail about elucidating the force required, while also taking into account the fuel used to propel the object also has mass and will add weight!

| Could we produce a micro kugelblitz with the proper application of current laser tech? Posted: 05 Jan 2017 09:48 AM PST Black Holes, (as I understand) can exist in many different sizes. From the supermassive ones in galaxy centers, to micro black holes that are so tiny they exist with a mass of just over 22 micrograms. With our current (or near future) high power lasers, and perhaps some use of slow light mediums, would it be possible for us to create a micro kugelblitz? [link] [comments]  |
| How do we know for sure that ALL elements beyond Oganesson (Z=118) are radioactive? Posted: 05 Jan 2017 04:40 AM PST Hi, I was reading about Oganesson, the element with the highest proton count yet synthesized. The article talked about the Island of Stability, possibly centered around Z=126. It further said that Z=184 and Z=196 are hypothesized to have closed neutron shells, which if true qouldmake them more stable. My question is, is it possible that one day we will synthesize some Z=184 or Z=126 and it won't be incredibly unstable/radioactive? How do we know for sure that ALL elements past 92 are radioactive? What if we're just currently in a part of the table where all the elements are radioactive but as we synthesize more and heavier elements we move out of the "radioactive" area of the table? Thanks. Edit: not sure if this should be tagged chemistry or physics. I don't like the tags because every time I ask a question it seems to fit more than one tag. I'm choosing chemistry for now, mods change it if you want. [link] [comments]  |
| What is the relationship between natural lifetime and bandwidth? Posted: 05 Jan 2017 12:28 PM PST As per title, What is the relationship between natural lifetime and bandwidth at given wavelength? (i.e. 694.3nm for Ruby laser) [link] [comments]  |
| Is entropy relative? Why are some configurations of matter inherently more disordered than others? Posted: 05 Jan 2017 10:12 AM PST Entropy is usually interpreted as a measure of 'disorder.' A common example is that a pile of sand has more entropy than a sand castle with the same number of sand grains - there are more arrangements of the sand such that it is a disordered pile than there are such that it is a sand castle. 'Disorder,' however, is a human concept. All piles of sand look similar to us, but are actually distinct in their arrangement of grains. Why is a sand castle inherently less disordered than a pile of sand? [link] [comments]  |
