| Posted: 05 Jan 2018 01:28 AM PST I found some references about O2 partial pressure in venous blood (40 mmHg). That makes me think that at low pressure you might actually lose O2 with every breath. An O2 partial pressure of 40 mmHg correspond to an altitude of about 10km which seems to match with the altitude where your time of useful consciousness drastically drops. Is that all there is to it?

| Is pyrolysis of food possible in boiling water under sufficient pressure? Posted: 04 Jan 2018 05:02 PM PST At sea level, boiling water will not reach high enough temperatures to cause pyrolysis, but if the boiling is done in a pressure vessel so that the water can reach higher temperatures before boiling, is it possible to char food? How high would that pressure have to be? [link] [comments]  |

| Posted: 05 Jan 2018 06:03 AM PST Every article I literally just refers to it as "Liquid Crystal," but what type of crystal, how is it made into a liquid? [link] [comments]  |

| Why does my body/legs/knees ache when I don't get enough sleep? Posted: 04 Jan 2018 08:12 AM PST I know how critical getting sufficient amount of sleep is for our bodies, but every know and then I'll only get about 3-4 hours of sleep and when I wake up, usually my knees are achey as if I just ran on concrete pavement for a few hours.. Nothing too bad. Any home remedies got that before I start my day? [link] [comments]  |

| How does scientist calculate the mass of celestial bodies? Posted: 05 Jan 2018 03:37 AM PST I am very much confused about this question. How does scientist calculate the mass of celestial bodies? [link] [comments]  |
| Is it possible for a eunuch to achieve orgasm? Posted: 04 Jan 2018 08:22 AM PST If a male has had both his penis and testicles removed, would it still be possible to achieve orgasm? Would the lack of sex hormones make it impossible? [link] [comments]  |
| Why does a Green Screen need to be green? Posted: 04 Jan 2018 04:03 PM PST |
| Could two protons produce a black hole? Posted: 04 Jan 2018 06:27 PM PST |
| Why isn't Juipter a homogeneous mix of gases? Posted: 04 Jan 2018 09:02 PM PST I love looking at the beautiful images coming out of the Juno spacecraft on Twitter and NASA websites. It reminds me of inkblots in water, where there is an amazing amount of detail in the ink before it fades out into a homogeneous color. But that got me thinking. If Jupiter is full of giant storms and is very old, why isn't it just a completely mixed planet by now? What dynamics exists that keep some parts (sometimes shockingly) different colors (and I assume wildly different compositions)? [link] [comments]  |
| If Jupiter was condensed, how big would it be compared to Earth? Posted: 04 Jan 2018 08:19 AM PST So from what I understand, Jupiter is entirely made of gas. I know that gases like helium have an expansion ratio, which is how much space it occupies when it evaporates. Is it possible to get an average expansion ratio for Jupiter and therefore a measurement of how large Jupiter would be (in physical dimensions e.g. diameter) if we cooled it enough to condense?

| Is it possible to insulate a house so well that HVAC isn’t necessary? Posted: 04 Jan 2018 07:33 PM PST I'm wondering specifically about climates that have a very wide temperature range such as in Ontario. If this is acheivable what R-value would it require and what other special requirements would it take? [link] [comments]  |
| Is there more matter vs anti-matter? Posted: 04 Jan 2018 09:16 PM PST When matter and a corresponding particle of anti-matter interact they annihilate. Does this indicate that there is more matter than anti-matter in the universe? I ask as I assume if they were the same amount it'd be constant chaotic destructive annihilations. My understanding is that so far as we have observed anti-matter acts like matter? Could the universe function as is if we instead had a saturation of anti-matter? Can energy be converted/is strictly matter or can it be anti-matter as well? Or am I way off base? [link] [comments]  |
