| Does the long term use of antidepressants cause any change in brain chemistry or organization? Posted: 10 Nov 2017 10:13 AM PST Meaning, any permanent changes that persist even after stopping? [link] [comments]  |
| How do modern laundry detergents compare to ones from 25 or 50 years ago? Posted: 11 Nov 2017 04:36 AM PST With most laundry detergents today advertising new and better formulas all the time, how much progress has there really been in the long term? Is it a lot easier to get clothes clean and stain-free today than it was, for example, in the sixties or the eighties? The reason I'm asking, is that I rarely see any unremovable stains or other problems with my clothes after a single wash in a 40C cycle - perhaps I see a problematic stain only once or twice a year. (This is with the exception of old clothes I use for yard work or car repair, which I don't expect to get clean at all). Yet, all the ads make it seem like stains are a huge issue - so is this just marketing BS, or is it something that would have been the case some time ago? [link] [comments]  |

| How does one read information from qubits? Posted: 11 Nov 2017 05:57 AM PST When the qubits are being read by the outside world, they would collapse - how do we make sure they collapse so that the information is accurate? [link] [comments]  |
| How can natural gas combustion produce CO? Posted: 11 Nov 2017 05:46 AM PST I've read that natural gas burning furnaces can cause CO poisoning if the gas improperly vented or combusted. But I lived in a flat with an unvented gas heater for years and never experienced symptoms of poisoning. Could it be that the flat was too drafty? [link] [comments]  |

| Will precession mean that this Veterans Day monument slowly goes out of alignment? Posted: 10 Nov 2017 11:56 PM PST If so, can we calculate by how much, or after how many years it will become noticeable? [link] [comments]  |
| How does brain decide which memory to keep and make it easy to access? Posted: 10 Nov 2017 05:13 PM PST I have watched the movie Seven only once, and it was like 10 years ago or so, and I can recall the first 10 minutes of the movie crystal clear, every word of every sentence. On the other hand when someone asks me about my father's birthday, I need to actively think to remember it. On subconscious level, my father should mean a lot more to me because he is and has been a big part of my life. So why do I remember dialogues perfectly in a heartbeat, from a movie I've watched 10+ years ago which is not even in my top 50, while I need to think for couple of seconds to remember my father's birthday?

| Why are London Dispersion Forces called dispersion forces? Posted: 11 Nov 2017 01:04 AM PST To disperse means to spread, so why are attractive forces named after something that seems to be opposite to what they do? [link] [comments]  |
| How does the sun cause colours to fade or wash out? Posted: 10 Nov 2017 06:58 PM PST Why do things left in the sun tend to fade or lose their colouring? [link] [comments]  |

| What voltage does the human body use to control muscles? Posted: 10 Nov 2017 04:33 PM PST As most people know the human body uses electricity to control muscle movement through contraction. I was wondering what voltage is actually used if at all comparable and just how similar the mechanism the human body uses are to the mechanism of electricity of a house and such [link] [comments]  |

| Is there a real threat to wasting water besides the money it cost? Posted: 11 Nov 2017 04:47 AM PST As kids they warned us about wasting water, but wouldn't running a lot of clean water down the drain help the sewage system by diluting the dirty water? [link] [comments]  |
| Does fusion occurs to some atoms in Jupiter/saturn due to Quantum tunnelling effect? Posted: 10 Nov 2017 06:53 PM PST Is there any other factor contributes to fusion other than quantum tunnelling? Do quantum tunneling probability increases with temperature/pressure? [link] [comments]  |
