Why is the bottom of the ocean so cold? With all that pressure, shouldn't it be ridiculously hot? Posted: 27 May 2016 08:28 PM PDT I was watching an Attenborough doco about creatures of the deep, and he mentioned that water temperatures drop drastically as you go deeper. That seems inconsistent with the drastic increase in pressure as you go deeper. This is all coming from my 1st year uni understanding of PV = nRT. My guess would be something like: warm water rises, cool water falls, you end up with a continuous cycle (like vertical currents) that regulates water temperatures even very deep in the ocean.

Quantity of soap required to affect a given amount of oil? Posted: 28 May 2016 04:52 AM PDT I have a basic understanding that soap affects oils by trapping them in water-soluble structures called micelles, which can be washed away by water. But how much soap is required for a given amount of oil? [link] [comments] |
When the Falcon 9 reenters the atmosphere for landing, why doesn't seem to need a heat shield? Posted: 28 May 2016 05:37 AM PDT Every craft in my memory seems to need a heat shield but here (https://www.youtube.com/watch?v=4jEz03Z8azc&feature=youtu.be) it seems to reenter without a problem. Is it going slower than capsules or shuttles would normally go, or is it returning at a different angle to reduce drag from the increasing air? [link] [comments] |
Posted: 27 May 2016 07:40 PM PDT Basically I was thinking if the singularity of a black hole hit some unknown degeneracy limit and started pushing back outwards how much space could the singularity expand into? I know for all intents and purposes the inner workings of a black hole are basically separate from our universe, but I was wondering if anyone knew anything about this. [link] [comments] |
Why doesn't light diffract through the 'mostly empty space' of an atom? Posted: 27 May 2016 07:36 PM PDT In this case, the 'the slit' is small enough for significant diffraction, right? [link] [comments] |

Why isn't acetaminophen (e.g. Tylenol) formulated with N-acetylcysteine? Posted: 27 May 2016 08:30 PM PDT Paracetamol toxicity seems to be a very significant public health issue--lots of overdoses leading to deaths and liver transplants. N-acetylcysteine (NAC), used as an early "antidote" for acute toxicity, is seemingly well-tolerated, cheap, and minimally interactive with other compounds (including paracetamol itself). The MoA appears to imply that concomitant administration could effectively prevent toxicity from ever happening. So why aren't paracetamol formulations--particularly "prescription strength," high-dosage ones--commonly made with included NAC? It seems like a very straightforward way to make paracetamol safer, but there must be a good reason that this doesn't happen. Thanks! [link] [comments] |
Why don't fingerprints change if skin sheds constantly? Posted: 27 May 2016 04:18 PM PDT Maybe this is silly, but I had a surgical incision on my thumb recently to get rid of a felon, and the skin on the entire top part of my thumb is shedding. Why doesn't my fingerprint change on my thumb? [link] [comments] |

Posted: 27 May 2016 04:45 PM PDT I don't buy out-of-season fruits at the store because I don't think they taste as good. My husband doesn't think my logic stand. [link] [comments] |

Are there known tidal effects on other planets? Posted: 27 May 2016 03:25 PM PDT |
Posted: 27 May 2016 12:03 PM PDT There are a lot of elements/compounds that react (sometimes violently) to the oxygen (or water?) in our atmosphere. Are there any that would be extremely useful in everyday applications if it weren't for their reactivity with common substances and ubiquitous gasses? [link] [comments] |
During internal bleeding where does the blood leak to? Posted: 27 May 2016 02:09 PM PDT I was always under the impression that blood vessels where more or less packed in surrounded by muscles and organs which wouldn't really leave much room for blood to pool into even if a vessel was ruptured.

Would we know if a distant galaxy was made up of anti-matter? Posted: 27 May 2016 12:43 PM PDT Would there be a difference in the light or radio signals or anything? Could there be huge amounts of anti-matter that looks just like matter? [link] [comments] |
What makes highly acidic and alkaline solutions so corrosive? Posted: 27 May 2016 01:24 PM PDT |
What is the difference between "sun" and "shade" plants? Posted: 27 May 2016 04:49 PM PDT Kind of a dumb question, but why is it that some plants do better in shade than in sun, or with less light in general? I can see where some plants would be better adapted to lower light conditions, but it seems to me that as photo synthesizers most plants would be happy getting plenty of sun. Thanks for your help!
