| Which one produces more energy with same input: one turbine or two turbines? Posted: 18 Nov 2017 06:53 AM PST For example, in steam turbines with the same amount of boiling water at the same temperature. Which would produce more energy - one or two turbines? Assuming cost is not a factor. [link] [comments]  |
| How does it smell on the space station? Posted: 17 Nov 2017 07:55 PM PST So I was wondering how it smells inside of the international space station. It looks like it wouldn't smell too bad, but it's a tube with no fresh air and a bunch of people, so I think it would smell awful in there. I am no man of science, so please forgive any sort of assumptions I made. [link] [comments]  |

| How to calculate evaporation time of water? Posted: 18 Nov 2017 04:24 AM PST Good Day! Is there a way of calculating the evaporation time of water? I have the area (A) of a container the height (h) of the water volume of the water (V) air humidity (x) the temperature (T). A= (pi*0.08252)m2 h= 0.065 m V= 1 L x = 45 % T = 22 degrees C. If you need more data just ask. Thank you in advance. [link] [comments]  |
| What would happen if you were hit by the Oh-My-God particle? Posted: 17 Nov 2017 08:50 PM PST What effect would an ultra high energy cosmic ray, on the order of the Oh-My-God particle, have on a human body? Would you notice it? Would it do damage do your DNA or other tissues? It seems like a particle traveling practically at the speed of light and carrying the energy of a fastball would have some effect.

| Is there a link between high IQ and success in artistic fields? Posted: 17 Nov 2017 03:52 PM PST I don't mean to ask if all artists have high IQs, so much as, are especially successful artists more intelligent than average? [link] [comments]  |
| Posted: 18 Nov 2017 06:34 AM PST I saw Alan Pan (from the YouTube channel Sufficiently Advanced) put an electromagnet from a microwave oven inside of a replica of Thor's hammer so that no one could lift it unless he switched it off. I'm not sure how long he would be able to keep the magnet on with the batteries he had before it would heat up. If I wanted to make something like that, what kind of power source should I use to avoid overheating but still have significant strength? [link] [comments]  |
| Posted: 17 Nov 2017 07:04 PM PST In the quantum world, an object exist in all states until observed. During the act of observation, something has to tell the object to pick a state. What is that message? [link] [comments]  |

| What's the difference between astronomy, astrophysics and cosmology? Posted: 17 Nov 2017 05:15 PM PST As far as I know, astronomy studies celestial bodies (including their characteristics and behavior), astrophysics studies things like general relativity, and cosmology studies the 'timeline' of the universe. (Sorry for the bad english). [link] [comments]  |

| How do subway systems add connectivity underground? Posted: 18 Nov 2017 12:46 AM PST I live in Toulouse, France which recently became the first French city to provide connectivity in the underground subways. This wasn't possible a couple weeks ago. Now people can talk on their phones, connect to the internet, text, etc. What had to change for this to become possible? [link] [comments]  |
| Posted: 17 Nov 2017 11:27 PM PST Each human on earth has unique faces, however some animal species birds like pigeons, baby chicks or fish like sardines, sea bream etc. look like sharing a limited amount of variations in their facial geometries therefore they become distinguishable only because of their colors, patterns and spots. It is also true that human brain is attuned to distinguish differences in human faces more than any other animal. Do such animals all have unique facial geometries? [link] [comments]  |
