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. submitted by /u/warandbuffett [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. submitted by /u/battletoads97 [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.

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.

What's the largest power source you could put into microwave oven transformer electromagnet before it would overheat within a couple of minutes? 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? submitted by /u/Evibear [link] [comments]

What data is transmitted to an object, such as an electron, that causes it to collapse from a probability function into a concrete observable?

At what frequency does my guitar vibrate when I strum multiple strings? Posted: 18 Nov 2017 04:21 AM PST I was wondering this. Since I play guitar, I can feel it slightly vibrate whenever I strum a "low" string. If what I remember is correct, the guitar will vibrate at whatever frequency the string is vibrating at. So if I strum multiple strings, at what frequency will the guitar be vibrating? How about on the piano where the low notes are lower? submitted by /u/Sparky_42 [link] [comments]

Can birds of the same species, (for example pigeons in the cities) share the exact same facial geometry(phenotype) unlike humans (distance between eyes, nose shape, forehead curvature etc) regardless of their feather color and spots? 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? submitted by /u/bertsteven1 [link] [comments]

What stops us from using a generated magnetic field as a radiation shield for the ISS, satellites and future crew missions to the Moon and Mars ? Posted: 17 Nov 2017 03:37 AM PST So, we know magnetic fields are pretty damn good for protecting stuff from radiation. We also know that humans tend to turn into a mushy goo when they have too much exposure in either duration or intensity (or both) to radiation. We also know that we can make some really powerful magnetic fields - enough to contain nuclear fusion. And we also know how to use nuclear fuel to generate high amounts of power. So what is stopping us from putting it all together and equip spacecraft, especially those carrying crew with a magnetic field radiation shields ? Obviously, there is a ton of math to do, but I haven't heard anyone ever talking about this even theoretically.

Why doesn't 0.1+0.2=0.3 in java? Posted: 16 Nov 2017 05:50 PM PST I am new to computer science in general, basically. In my program, I wanted to list some values, and part of my code involved a section of code where kept adding 0.1 to itself and printing the answer to a terminal. Instead of getting 0.0, 0.1, 0.2, 0.3, 0.4 ect. like I expected, I got 0.0, 0.1, 0.2, 0.30000000000000004, 0.4 Suprised, I tried simply adding 0.1 and 0.2 together in the program because I couldn't believe my eyes. 0.30000000000000004 So what gives? submitted by /u/TheSkybox [link] [comments]

Can alcohol intake during early pregnancy affect the embryo/fetus before the umbilical cord is developed? If so, how? Posted: 16 Nov 2017 07:18 AM PST I have often heard that alcohol intake during the first few weeks of pregnancy is harmless, due to the embryo getting nutrients not from the mother but from the yolk sac. I've tried to read up, but haven't found anything conclusive. Wikipedia confirms that the umbilical cord is not developed until week five, supporting the "harmless-hypothesis". But other sources claim that the embryo/fetus can indeed be affected by alcohol intake before week five. According to this article written by a researcher at the ASU, "in the third week after fertilization that specific alcohol-induced birth defects begin to affect the developing embryo". The article lists many aspects of how the early development can be affected. I've seen loads of other sources claim the same thing. But how does this work, if the embryo/fetus is not even connected to its mothers bloodstream yet? submitted by /u/Mewwy_Quizzmas [link] [comments]

How do force carrier particles explain attraction between particles? Posted: 16 Nov 2017 03:49 AM PST I know for example that protons and electrons communicate with each other through the electromagnetic force, but I can't seem to grasp how this results in attraction. The repelling between the same charges I can somehow see (with the photons 'pushing' the particles in opposite direction), but this is probably dangerous classical thinking in a quantum world? Same with gravity by the way. How does the moon, for example, provide the communication with the earth that it has moved, creating tides? submitted by /u/dreakie92 [link] [comments]

Is there a limit to how often a particle can quantum tunnel? Posted: 16 Nov 2017 05:44 AM PST Lets take an electron and a small transistor for an example. It is said that if a transistor is too small, an electron can quantum tunnel through it. I was wondering, if an electron tunnels to one side, is it possible for it to tunnel back quickly? If so, does physics give any hard limits to how quick this back and forth action can be? Does it matter if instead of having an electron jumping the same transistor twise, the electron instead jumps two nearby transistors in a row? submitted by /u/empire314 [link] [comments]

Why is Lithium present in most of the strongest bases ? Posted: 15 Nov 2017 03:04 PM PST It seems like lithium is omnipresent in every strong bases such as tBuLi n-BuLi LDA etc..

How can electrons can travel faster than the local speed of light in Cherenkov radiation? Posted: 15 Nov 2017 12:36 PM PST While electrodynamics holds that the speed of light in a vacuum is a universal constant (c), the speed at which light propagates in a material may be significantly less than c. For example, the speed of the propagation of light in water is only 0.75c. Matter can be accelerated beyond this speed (although still to less than c) during nuclear reactions and in particle accelerators. Cherenkov radiation results when a charged particle, most commonly an electron, travels through a dielectric (electrically polarizable) medium with a speed greater than that at which light propagates in the same medium. https://en.wikipedia.org/wiki/Cherenkov_radiation OK so I understand that C is a constant and that light doesn't always travel at that speed, and only does so in a vacuum. But, I don't understand how these electrons can travel faster than the local speed of light (in that medium)? One analogy I can think of is that a cheetah (light) is faster than a shark (electron) on land (vacuum), but in water (medium in Cherenkov radiation) the shark would be faster, but still not as fast as the cheetah is on land. This is because the shark is better suited for water. Is this analogy accurate? So does this mean these electrons in Cherenkov radiation are for some reason better suited in this medium than light is? If so, why? Or is there another explanation? I don't understand how an electron can be better suited since photons of light seem to have everything going for them including size and mass. Can the light be made to still go faster than the electrons in this medium if someone wanted to? Thanks. submitted by /u/ArosHD [link] [comments]
