| What happens if a quantum entangled particle B is sent through a BBO again? Posted: 15 Jul 2017 03:17 AM PDT (I'm just a curious noobie asking questions :-) ) Shooting a photon beam into a nonlinear crystal (BBO) is a method (SPDC) of creating two streams of quantum entangled photon pairs in superposition. The first stream of particles is called stream A, the second stream is stream B. What happens if the second stream is directed into a second BBO crystal again and one obtains two new streams of B1 & B2 particle pairs?
If option 1 is valid: do the Bell test results of the streams of B1 and B2 particles change if the particles in stream A are measured first? (likely not, correct?) I am quessing the Bell test results of the B1 & B2 pairs must be unchanged, and that means all B photons were forced into a state collapse, correct ... ? Is there any type of experiment that creates a super-superposition ?? ( ... GHZ?) [link] [comments]  |
| Does what my mother ate while she was pregnant with me effect what I like/don't like to eat? Posted: 14 Jul 2017 08:35 AM PDT When my mum was pregnant with me she ate a lot of oysters (and I mean A LOT - like several dozens a day, most days). I personally find oysters to be gag-inducingly foul without exception, always have. Whenever I've mentioned this to my friends they often seem to have an especially hated food that their mother craved a lot during pregnancy. Is there an actual correlation here or is it just a coincidence? EDIT: Thanks to everyone for all the replies! I wasn't expecting such an enormous response. Appreciate it a lot. [link] [comments]  |

| Can you dream optical illusions? Posted: 15 Jul 2017 12:14 AM PDT Last night I was having a dream in which I was trying to show someone images of M.C. Escher's work. no matter what I tried in my dream I couldn't get google images to work, then my keyboard turned to Lego and I woke up. This left me wondering if it's possible for the subconscious mind to visualise physically/structurally impossible optical illusions? I've just woken up and this may make no sense, but I'd like an answer! [link] [comments]  |
| How do lithium ion batteries work? Posted: 15 Jul 2017 01:44 AM PDT Hi folks, I start a one month internship on the 24th and I've just received an email from them about preparation - they want me to learn all about lithium ion batteries! "Depth of discharge, state of health, state of charge, capacity, cycle life... Mainly on how to measure them, how they are affected, etc." This isn't exactly my field of expertise so any tips would be much appreciated! Most informative comment gets a cookie.

| Are there any new emerging fields of mathematics? Posted: 14 Jul 2017 10:36 AM PDT Some scientists say, that we don't understand fully quantum mechanics, because the math we need to solve some problems isn't even invented. Are there any papers or proposals on fundamentally "new" mathematic fields, which are emerging? From my knowledge lie-groups, grouptheory and probabilistic theory were the last big areas in mathematics, which were invented (correct me if i'm wrong). And by "new" I just mean: inherently different from the approach on solving some problems. P.S.: I know this question can trigger some mathematicians, because I may oversimplify some things. Sorry for my lack of knowledge. [link] [comments]  |
| Is water truly uncompressable? Posted: 14 Jul 2017 09:12 PM PDT I've heard so often that liquid water cannot be compressed, but is it really impossible? I've searched the topic and the results all seem to refer to it not being practically possible. But under hypothetical circumstances, say extreme gravity in the core of a planet or something, would it compress? If possible, my best guess would be that it becomes ice, only really hot.

| Posted: 14 Jul 2017 06:43 PM PDT This last section of Business Insider's article on Juno's findings mentions,
Won't the final plunge into Jupiter be the best opportunity to collect images and other data since it'll be Juno's closest (and last) encounter with the planet? I do understand the probe may not be able to stand up to the forces of entry into the atmosphere and therefore won't be able to collect data from then on (correct me if that's wrong), but up until entry will Juno still be collecting information? Links and other knowledge of this will be greatly appreciated, and please keep vocabulary and other jargon to the basics please! [link] [comments]  |

| Autism is a spectrum. Is there a spectrum for people with sociopathy and psychopathy? Posted: 14 Jul 2017 08:04 AM PDT I'm not an expert or a psychologist, but the way we talk about pathology is different than the way we talk about autism. There are people with autism we call functional. There are people with autism who need a lot of outside help. Is it the same for anti-social disorders? Are there people with small amounts of psychopathy? What about ones that don't commit full on murder spree but they do leverage economic power for their personal gain? What about that horrible mother in law or bully from high school? Are there small amounts of pathology leaking into their peaceful everyday existence? Or is pathology simply "on" or "off" in each person? [link] [comments]  |

| Posted: 14 Jul 2017 07:46 AM PDT Currently I'm 22 and have grown out of my asthma so I only have an emergency albuterol inhaler for if I get a cold or the flu, which is the only time my asthma ever bothers me now. As a kid growing up in New England though, the winters were the absolute worst for me. Those cold months would be riddled with asthma attacks, however in the summer I would rarely if ever have an attack unless brought on by strenuous physical activity. I've always been very intrigued by medical science and I remember reading somewhere that in the early 20th century doctors would bring patients with severe lung related ailments to the American Southwest because it was hot, dry, and largely unaffected by industrial pollution at the time. So I was wondering if there were any areas like the Southwest U.S. or just any populations at all that are completely free of asthma? [link] [comments]  |

| How does the anisotropy/transmission axis of polarizers work? Posted: 14 Jul 2017 01:48 PM PDT So polarizers have optical axis that block or let through the corresponding polarizations of light, but it also depends on how much the polarizer is rotated, like shown in Malus's Law. Somehow, the polarizer isn't the same when viewed from all direction or otherwise the light transmitted would all be the same regardless of polarizer orientation, so what is it about the polarizer that makes it have a directional dependence on light transmission?

| Why do racecars have wide tires? Posted: 14 Jul 2017 08:46 AM PDT I recently learned that surface area does not influence the friction so why are the tires so wide? [link] [comments]  |
| Why does the buoyant force experienced while in water have contradictory effects on movement? Posted: 14 Jul 2017 05:12 PM PDT It's something that I've always wondered. While in a pool, we have a "lighter feeling" as though gravity affects us differently compared to being outside of water. However, this lighter feeling only seems to apply to jumping, hand stands, and vertical movements in general. When actually trying to move in water, we seem to have the opposite effect and feel "weighed down". I'm assuming it's because of the density of water, but it's still a head-scratcher as to why we feel "weighed down" with some movements and "lighter" with others- particularly horizontal vs vertical movements.
