If every digital thing is a bunch of 1s and 0s, approximately how many 1's or 0's are there for storing a text file of 100 words? Posted: 17 Nov 2017 04:43 AM PST I am talking about the whole file, not just character count times the number of digits to represent a character. How many digits are representing a for example ms word file of 100 words and all default fonts and everything in the storage. Also to see the contrast, approximately how many digits are in a massive video game like gta V? And if I hand type all these digits into a storage and run it on a computer, would it open the file or start the game? Okay this is the last one. Is it possible to hand type a program using 1s and 0s? Assuming I am a programming god and have unlimited time. submitted by /u/Virtioso [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.

In what ways, if any, are a woman's eggs affected by unhealthy habits prior to pregnancy? Posted: 16 Nov 2017 11:53 AM PST I've read that a woman is born with all her eggs already stored in her body, contrary to men's sperm being constantly recycled.

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]

If not, is there a particular niche where it would be financially viable? submitted by /u/tonygoold [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 does a radio play static or white noise when there is no signal rather than silence?

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.. I suspect it has something to do with its size as it is one of the smallest atom. Bonus question : Why is tBuLi more basic than n-Buli ? Does it come from the fact that the resulting carbanion is more stabilized from inductive effects ? submitted by /u/iliketrains78 [link] [comments]

How much do catalytic converters help the environment if used on old cars? Posted: 15 Nov 2017 01:33 PM PST As a lover of old cars and someone who is now concerned about the environment, how much would adding a catalytic converter help reduce bad exhaust gasses? I know what they do and how I just don't know if I should really be concerned about putting one on my car that isn't under regulatory scrutiny.

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]

Have flying insects evolved ways to combat spider webs? Posted: 15 Nov 2017 03:09 AM PST I noticed a duel of sorts between a moth and a spider just now where I was certain the moth was doomed as it flew into the section where a spider had firmly set up its web, but as it flapped its wings so quickly it tore apart the web, and even sent the spider fleeing. I don't know if this in itself was an adaption to webs, in fact I'd say from an uneducated standpoint that I doubt it... but it did make wonder if there were other insects which had developed natural tools against spider webs. submitted by /u/Demderdemden [link] [comments]

Is there a good reason the grizzly bear didn't spread east to Quebec? Or Siberian tiger west into Europe? Posted: 14 Nov 2017 09:07 PM PST Both tigers and brown bears cover huge swats of land with very varied climate. Yet they don't (and didn't, according to this) ever cover the continents east to west. It seems to me that the habitat should fit just fine, and the area between as well seems easy enough to cross for these species? Is it because of humans?

Does air temperature have any effect on sun strength? Posted: 15 Nov 2017 06:04 AM PST I'm aware that the angle of the sun is what matters and that the sun is higher in the sky in the summer, but even a summer evening sun feels so much hotter than a midday winter sun. Is this just perception due to air/body temperature, or is there something about the atmospheric conditions that changes the strength of the sun? submitted by /u/mcjiggerlog [link] [comments]

Is it possible to have water-fueled cars? Posted: 15 Nov 2017 07:43 AM PST Is it possible to have water-fueled cars? I know about hydrogen-fueled cars, but water (H2O)? I'd also like to gain some understanding why, particularly on the molecular level. I assume there are numbers on how much energy is necessary to start the chemical reaction that releases the energy to -- say -- fuel a car. I also assume that the energy needed to start a reaction with H2O is much higher than what is released. Or maybe the energy needed is just so high that the engines would become massively huge. I don't know. Please don't stop at technical terms. I would research anything I don't understand. But please don't exxagerate :) submitted by /u/Caleb__ [link] [comments]

Would a bullet fired from a gun really fall at the same rate as one dropped from a the same height? Posted: 15 Nov 2017 02:32 AM PST There is the common adage that bullets fired from a gun and those that are simply dropped will hit the ground at the same time. Though it makes sense that Earth's gravity would affect objects of similar weight in the same way, couldn't the bullets spin and or speed put it in a sort of short and doomed orbit?

Posted: 14 Nov 2017 04:12 PM PST In my limited exposure to fruits I have yet encountered other kind of fruit that has actual free flowing liquid stored inside. I'm curious as to how it is produced. And what is the purpose of keeping liquid inside the fruit. submitted by /u/minikid01 [link] [comments]

How do neutron stars generate a magnetic field? Posted: 14 Nov 2017 05:19 PM PST If they are composed entirely of neutrons, there is no separation of electric charge. If there are no moving electric charges, how are the strong magnetic fields generated? submitted by /u/_bobby_tables_ [link] [comments]

Why not use thermoelectric generators (TEG's) on nuclear cooling towers? Posted: 15 Nov 2017 05:42 AM PST A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. (Wiki). It seems to me that we are just wasting the heat and the power that could be produced from said heat, could we not just attach the TEG to the outside of the tower with heat sink compound and then on the cool side have a metal heat sink? Would this not both reduce waste and decrease the impact nuclear power generation has on the environment? Technically it should be able to pay for itself wouldn't it? submitted by /u/Asylumsix [link] [comments]
