What are padded or performance horse shoes and is there some kind of controversy with them?	[ "Horse shoes come in hundreds of different styles, in various materials. They all have a specific purpose or goal. Performance shoes are generally designed for racing, they're lighter and grippier than a standard work shoe, which should provide an advantage. It's like switching your boots out for some running sho...	[ "Look at the sign of the [Hall conductivity](_URL_0_). For the experimental setup, it's easiest to look at the picture in the \"theory\" section of that wiki page. The voltage that you measure will have opposite sign for n versus p type doping." ]
Why are there other ingredients inside of water bottles instead of just purified water?	[ "Natural spring water, and tap water from aquifers, contain many dissolved minerals. This gives water from different regions or different springs different taste. Pure distilled water tastes weird compared to water with dissolved minerals because all the water you'eve ever drank has been mineralized to some degree...	[ "California has really strict laws. The exact wording is just to comply with a particular labeling law required by the state. And since it makes sense to give the same products to California that you give to the rest of the US, it's common for many products to have the warning printed on the label. Realistically, t...
How do tax returns/refunds work in Canada?	[ "If you’re working and getting a paycheque, you need to file income tax. Early in 2019 (Feb - Apr) you will get a T4 and you will use that to file your taxes." ]	[ "I don't know where you experienced this but I do it all the time. I bought a tv one day. It came up to $500 and something. I handed the dude 4 100 dollar bills, and told him I was going to put the rest on a card. He punched in the $400 and got my new Total of $100 something. Then I ran my card like normal." ]
Does alcohol evaporate faster than water?	[ "Not a chemist, but I think the answer is yes. Alcohol feels cool on the skin because of rapid evaporation. I think the answer would be found in the vapor pressure numbers. According to a chart [here](_URL_1_) for water, the vapor pressure at 20 C is 2.34 kPa, while the [similar chart for ethanol](_URL_0_) shows a ...	[ "Your sense of smell works by picking up molecules from the air. Many things emit these molecules regularly. \"Volatility\" is a measure of how frequently something will emit an odor-causing molecule. When temperatures increase the speed of atoms increase, which leads to an increase in volatility. Basically, you s...
What do we know about precolonial Northern East Africa (Somalia, Ethiopia, Djibouti, Eritrea)?	[ "Prior to the colonization of East Africa, the regions of Ethiopia and Eritrea (known as Abyssinia) had many individual cities, such as Malinidi, Kilwa, Great Zimbabwe, and Sofala, that were major centers of trade. These cities exported mostly slaves and gold to other civilizations along the Indian Ocean such as th...	[ "Occupied Estonia was a pretty swanky place in the late 70s - 80s if you had the cash and the connections that allowed you into those swanky places. My parents used to go out on weekends to fancy places like [hotel Viru](_URL_6_) that had foreign tourists and good drinks as well as disco music. That hotel was also ...
[Mathematics] Probability Question - Do we treat coin flips as a set or individual flips?	[ "Before the coin is flipped at all, the chance that it will come up heads 11 times in a row is 1/2048 (not sure where you got 4%). However, as you gain information, the probabilities of various outcomes will change. For example, the probability of getting tails 11 times in a row is also 1/2048 before you start flip...	[ "Well one way is by selected specific people for your study. The studied that showed evidence that vaccines caused autism actually dropped people from the study who had children not become autistic, found children who had family history of autism to include in the study, and kept the numbers small. Another way coul...
why don't competing companies mutually agree to raise their prices, which would increase revenue?	[ "Because they really don't like the idea of going to Federal Pound-Me-In-The-Ass Prison. It's called [price-fixing](_URL_0_), and is illegal." ]	[ "It's not practical or just. If you break my toy and I break yours then now we have two broken toys. A better approach is that if you break my toy then you replace it. Likewise, if you cut off my arm and I cut off yours then we're both screwed and I'm still down one arm. Better if you compensate me somehow than me ...
I'm studying a course in Engineering and....	[ "Either you're misunderstanding the example given, or whoever gave you the example is confused. The only thing I can think of that might make sense is if the professor were trying to explain how different geometries can have different properties, so that the distance between A and B in a straight line (i.e. throug...

Edit-- * If playing through the speakers, your headphones are wireless and the signal sounded fine: digital comm problem (im...
When DSCOVR arrives at the Sun-Earth L1 point, will it find an assortment of collected space debris similar to Jupiter's L4 and L5?	[ "Nothing of note to worry about. We have or have had several probes there already: ISEE-3, SOHO, ACE, WIND and there is nothing larger there. The L1-3 points are to unstable for any long term natural objects to reside there for any length of time. We do have an asteroid at the L4 point, and there is some dust at L4...	[ "That would depend on who and when the determination was made, and the intelligence of the being to recognize the evidence. For example, lets assume all visible signs of human activity were non existent, would some future being recognize our existence because it found evidence of plastic in the genetic code of fish...
What would happen if we got rid of Daylight Savings time?	[ "Most studies have shown that the energy savings are negligible if not completely nonexistent, so basically nothing would happen. We just don't because our government is decaying and sclerotic and can't get anything done, even non-controversial stuff." ]	[ "Yes, vitamin D synthesis is impaired, which may also explain higher rates of hypertension, diabetes, and some cancers. This article covers it: _URL_0_" ]
Historically did pregnant women know not to drink alcohol?	[ "Additional question: Was alcohol ever considered more of a concern than the usually unclean well water?" ]	[ "Do you have a particular geographical region or time period in mind? You're more likely to get a good answer if you are more specific than \"people in the past\"." ]
Why does the calorie count of an egg change depending on how you cook it?	[ "Do you have a source for this change? I have never seen it. Where are you getting your numbers? Are you asking if it changes, or are you asking why it changes?" ]	[ "From the top comment on youtube: The pan is so hot that the water doesn't even touch it. The lower surface of the drop of water is evaporating so fast that it rests on a permanent high pressure cushion of water vapour between it and the pan, and this cushion of vapour also acts as an insulator which means that t...
I've heard shower sex is uncomfortable, why is water such a bad lubricant?	[ "Wet surfaces stick to other wet surfaces. It's called cohesion when like substances stick to themselves. When both male and female genitals get really wet, they tend to stick and create more friction. That's why it's uncomfortable." ]	[ "From a person who isn't really into it. Prob my older age and other factors. Pro- sharing something with your SO Con- accidentally seeing something you can't unsee Pro- finding something that excites you Con- comparing your body and performance to the stars Pro- using it to help either partner climax Con- depende...
[Physics] Why did Madame Wu use Cobalt-60 in the parity symmetry violation experiment?	[ "^(60)Co beta decays with a very high branching fraction to an excited state of ^(60)Ni, which then decays by two gammas in cascade. The gammas are detected in coincidence, and since the electromagnetic force is parity-symmetric, they can be used as a control. The beta decay itself is a weak process, so an asymmetr...	[ "> Jackie Mitchell was able to strike out both Babe Ruth and Lou Gehrig in succession, which shows women aren't incapable of competing with men. That's not a valid conclusion. In a sport where a .300 average is good, it is not unusual for two top hitters to get retired back to back. They also happened to be the fir...
Is sweat conductive?	[ "Yes. Sweat is basically water with a bit of minerals and other stuff in it. In particular the salt in sweat makes it conductive. _URL_0_" ]	[ "Actually despite conventional wisdom, [doing so actually did absolutely nothing to make the game work better](_URL_0_). Quite the opposite, in fact -- your moist breath may have actually aided the degradation of the same components that most believed they were \"cleaning\"." ]
Do dogs really love their owners, or are they just really good at getting us to feed them?	[ "Super subjective question and I’m no dog behavioralist, so this is speculative. Dogs are pack animals, the same as us. Love is a very strong emotion, and one of its primary functions is to bond members of a group together. Although we may experience more nuanced and complex versions of emotions, I believe that the...	[ "There is a ton of debate on it. One perspective is that it is just a way to manipulate people into playing into your suggestion because it is expected in front of a crowd. Basically, if you ask random person to do X in front of 10,000 people...he will probably do it. Another perspective is that it's a little deepe...
Why do the majority of living things, like animals, insects, and bugs, require oxygen to survive?	[ "Living cells need Oxygen to react with the food we eat to get energy - It's basically the same thing as burning, but much less ''violent'', and produces the same waste (Co2). Oxygen is used for this due to how easily it reacts, but it's possible to use other gasses as well. There are lots of bacteria that do not n...

How do we get vitamin D from the sun?	[ "We don't, or at least not directly. The ultraviolet radiation drives [a chemical reaction]( _URL_0_ ) in our skin that creates it." ]	[ "They don't. They have really really good camera's that can take a picture from really far away." ]
Berlin Wall - Why did the Soviets care if people left East Berlin?	[ "1. To answer your first question, at no point did the wall enter Western territory. As shown in [this map](_URL_0_), West Berlin was actually smack in the middle of East Germany, due do the Allies having separate partitions for Berlin and the rest of Germany. The wall was usually set back a few meters into Eastern...	[ "Think of it this way. I own a house. In this house I allow several drug dealers to ply their wares. I don't sell drugs, I don't use drugs however I do FACILITATE knowingly, the use of drugs by my direct action and I am profiting off of it. Basically that's why, they know that they where facilitating the exchange o...
Can there be a planet where gravity is so strong a rocket can't lift its own weight?	[ "Yiu are probably always going to be able to make an explosion powerful enough to lift stuff momentarily (at least so long as you don't live on a white dwarf). But interestingly earth is pretty close to another limit for chemical rocketry. To get to orbit you have to bring fuel with you and speed it up to nearly or...	[ "Very careful simulation based on testing data. Engineers have experimentally gathered data about all the different materials used to make the telescope. This data includes failure points given applied loads, vibrational frequencies, etc. They can use this along with a computational model of the sattelite to predic...
What's to prevent me from shooting down a blimp with a sniper rifle from far away?	[ "I suppose the same thing that prevents you from shooting pedestrians with a sniper rifle. Either a sufficiently developed human conscience, a healthy fear of legal repercussions, or at minimum a better hobby." ]	[ "So the TL:NR is going to be \"That line doesn't really do jack\" here's why: Like someone using music or audio without consent saying \"Blahbity blah belongs to such and such, no claim to copyright is made\" or some such gives you no legal protection in court should that person decide to sue you the same is going ...
Is it actually bad to mix battery brands, or is this a marketing trick?	[ "If I could jump on this question, is it really bad to mix rechargable and standard batteries?" ]	[ "Words that often appear together are called \"collocations\", and it's simply the way we've learned them. We tend to process them as indivisible units -- phrases, rather than separate words. For example, when we say \"apples and oranges\", we're not thinking of two different kinds of fruit and then putting them in...
What differentiates a "cuss word" from a normal word?	[ "Well, in some sense, words are defined by what meaning people ascribe to them. So, a word is a cuss word or otherwise vulgar because people ascribe to it a meaning or connotation of vulgarity. Bad words are bad because people believe them to be bad / insulting. But if we dig a little deeper, cuss words tend to hav...	[ "Although most Americans have cable TV service, and get all their TV that way, network TV shows are also broadcast over public airwaves, and the networks have to lease broadcast spectrum from the government to do this. Because of the First Amendment, the US government usually has little or no control over the conte...
Why are the states in the east coast of the USA smaller than the west coast?	[ "Most of those states began as colonies of Great Britain, and colonies tend to be smaller political units than provinces or states. Additionally, the East Coast states were incorporated as they were settled, while the boundaries of the West Coast states were drawn at a time when the land in question was already bot...	[ "Different gasoline taxes. Different distances between the nearest refinery. Different blend requirements for the gasoline(California). Different requirements on who's allowed to pump gasoline into a car(Oregon/New Jersey). Different minimum wages. Different property values for a gas station sized plot of land. Dif...
In places where plant life dies in the winter, is there noticeably more O2 in the summer?	[ "The amount of CO2 in the atmosphere fluctuates significantly on a yearly basis. This is due to the northernhemisphere having much more landmass than the south. In winter plants materials generally rots in the north releasing alot of CO2 which gets reabsorbed when spring arrives. I'm sure the O2 levels in the atmos...	[ "Not really. It would take a lot of mutations to change the physical structure of a human, or any other animal. All the extra oxygen did before, was alter the range of possible mutations where an animal could survive. It didn't make animals bigger. it just made it possible for bigger animals to survive." ]
How do you remember taste and smells?	[ "related question: is it the same way as remembering sights, sounds, and textures? what about other stuff like \"sense of balance\" and \"sense of time\"?" ]	[ "The genetic explanation (very, very unlikely): The part of your DNA that lets your tongue cells build receptors (sensors) that detect bitterness broke after you and your brother split from being one entity into two. You have a mutation in your DNA that he does not. The physical explanation (most likely): You had t...
Why don't wild horses hooves grow out of control?	[ "Those horses were left in a stall without much freedom to roam. Wild horses are constantly wearing down their hooves when they run over rocks, gravel, and overall rough terrain. A wild horse will travel much farther than a captive horse in a day." ]	[ "We do know how to make it and actually can make better with modern processes. This is one of those yarns about ancient technology being mysterious and better. Total BS." ]
Is inflation ever going to stop? Will chocolate bars that cost $1.50 today cost $1000 someday?	[ "It's going to continue as long as humans keep introducing value into the economy. Are we going to get to the point where candy bars cost $1000? Maybe. Maybe the US won't be around that long. Maybe we'll replace the dollar with the new dollar to get prices back to a lower point like Mexico did in the mid-90s with t...	[ "> ... why can't I \"get use\" to the food? In some cases you do. A significant number of food allergies are childhood phenomenons that someone does eventually grow out of. And a study from Stanford not too long ago concluded that it is possible to prevent allergies, peanuts in particular, by exposing new borns to ...
Does alpha decay lead to an ion being made as the atom has lost two protons and so now has two more electrons than protons?	[ "Yes conservation of charge means that the resulting atom will be in a -2 charge state. Generally this state is not stable and the atom will interact quickly with local chemistry in some way to lose that charge. Some smaller atoms may even emit one of the electrons directly without requiring a reaction with local c...	[ "Quarks don't only come in pairs! Quarks and antiquarks have to appear in combinations that are neutral with respect to the kind of charge the strong force depends on (which is a bit more complicated than the + and - of electric forces). You can get neutral combinations with 3 quarks; with 3 antiquarks; with a quar...
How does traffic on the freeway happen if we are all going the same speed?	[ "Sometimes, people slow down to change lanes, enter, or exit, or because there's construction. It can take a little bit for even a minor slowdown to ripple all the way back through traffic. If it's a more major slowdown, more and more cars coming up behind it will be affected and have to slow down, too. This video ...	[ "You may as well ask why everyone everywhere doesn't get a long. They aren't in it for anything but the money, and sharing that money with someone else is not appealing. Basically the various gangs and cartels could never stick together long enough to make this work. They'd stab each other in the back and go back t...
Do people who live alone or in a small group in a remote area ever get sick?	[ "Strict isolation is an effective means of preventing the spread of communicable disease. If you never encounter a pathogen, then you will not become infected with it and will not become ill. This sort of isolation is, in theory, possible but in practice, doesn't really exist nowadays. People who are in this theor...	[ "Assuming by \"rural\" you mean not in any city or town: In America you can buy any plot of land that is for sale that you can afford, no application required.

Now using that same teaspoon, remove the chocolate from the milk." ]	[ "It lives in people and animals -- just in smaller numbers when it's not \"in season.\" It does't go 100% out of circulation." ]
Why do we experience brainfreezes when we consume cold drinks too fast?	[ "Brainfreeze is caused by your nerves not being totally connected in obvious paths. The trigeminal nerve serves the forehead as well as the roof of the mouth. The brain processes \"too hot\" signals from the roof of the mouth correctly, if you sip a hot beverage. Alas, \"too cold\" signals get mistaken for \"bumped...	[ "There are two things that make ice cream soft - the ice is in very small crystals, and tiny bubbles of air mixed into it. When you melt and refreze it, some of the air bubbles merge to create bigger bubbles with more solid material around them, and the ice crystals that form are much bigger, tying the mass togethe...
Why does spinning around many times and fast makes us desoriented?	[ "Your sense of balance, or equilibrium, is determined by a fluid, and the position of stone-like things in it within the inner part of the ear. When you vigorously spin around you shake up these stones, so when you stop spinning they are still moving about causing you to feel dizzy." ]	[ "I don't so much think of it as an evolutionary thing. There's really no benefit to being confused. It comes down to computing power. Your brain just takes a minute to recall old information/piece together new information to develop an idea of where you are and how you got there. I'm currently in flight school and...
How does the defrost lines on the rear window of my car work?	[ "They’re basically just very thin wires. Pass an electric current through them and they get hot. Presto, your window starts to heat up and defrost/deice." ]	[ "Are you sure it is not water condensing on a cold surface or a layer of ice on the surface melting?" ]
Why are certain allergies more common than others?	[ "Allergies occur when the immune system thinks a foreign chemical is harmful and releases inflammatory chemicals like histamine. Data indicates that allergies are partly genetic. Studies with twins reveal that among identical twins, if one twin has an allergy, the other has a 70% chance of having the same allergy, ...

What is the difference between House, Jungle, Trance, and/or any other genres of Electronica/Techno?	[ "Check out [this Flash site](_URL_5_), which explains it in great detail, but as a disclaimer, Ishkur can be pretty opinionated and condescending at times. Not everyone who's into electronic music agrees with him all the time." ]	[ "There is no definitive genome, as you said each individual will have slight or more than slight differences. For model organisms like mice, they are so inbred that the differences between individuals of the same strain are much less than for example with humans. Even for mice though, the \"official\" genome ie. th...
If the universe had a definite boundary, what would it look like, what would we see?	[ "It's very unlikely that the universe would have an actual boundary. We don't expect to come across an unbreakable wall in space, that would be weird. There are two possibilities : 1) The universe is infinite 2) The universe is finite, but has no boundary. The universe would be looping on itself, and when you trav...	[ "It isn't expanding into anything. Imagine an infinite loaf of raisin bread rising as it bakes. Each raisin in the loaf will be further away from every other raisin, since the loaf is expanding and the distance between all of the raisins is growing." ]
Re: The Manhattan Project; What sort of calculations could the mechanical computers of that era perform that were of interest to the scientists making the bomb?	[ "Initially, they used them for computations regarding explosive lensing. The punch card machines took months, so most of the \"computers\" were people with calculators. _URL_1_ Edit: they also did statistical modeling for probabilities of particle collisions. This is how the [Monte Carlo method]( _URL_0_) was devel...	[ "All those computers cost money. AWS sells time on those computers. When paying customers want to use them, the pi folks have to wait.

Why is it that humans go insane after extended periods of isolation but animals can live their entire lives alone and be perfectly fine?	[ "It is nearly impossible to determine how sane or insane an animal is." ]	[ "If you go to a major retail chain, all of the employees wear the same uniform, and look rather similar. If you go every day, you will start to learn to tell the individual people apart at a glance, and learn their names. The answer is experience. We have seen so many animals of that species, we start to learn to t...
In evolution how did sexual differentiation come about, like males and females?	[ "[Ah, wikipedia :)](_URL_0_). The reason is genetic diversity. If you have two genders, that's twice the genes to one specimen (baby), which allows helpful gene selection to occur. The species then evolves quicker." ]	[ "There is no evidence to support a difference in swimming speed. However, the difference in the mass of X and Y chromosomes _is_ used in many artificial sex selection methods." ]
Why do we learn in driving school to only use the right foot for the gas and brake pedal instead of using one foot for one pedal each?	[ "One point to make is that if you ever need to learn how to drive a manual transmission, having a habit of left-foot braking can be disastrous. Also, using the same foot for gas/break forces you to remove the foot from one before engaging the other." ]	[ "\"Stochiometric\" is the ratio of air and fuel. Ideal stochiometric for a gasoline-powered car at sea level is 14.7:1, air:fuel. If you are running rich, there is more fuel in the ratio. The additional fuel can add carbon build-up, which can lead to predetonation issues and other things. If you are running lean,...
How come Boston did not merge with its surrounding towns-such as Somerville, Cambridge, Brookline-in the 1800's unlike York City, which joined 5 boroughs into one city?	[ "To go off this, why is New York City so big? I know in Michigan there were laws prohibiting cities from annexing over county lines, halting the expansion of Detroit north into Oakland County. What let NYC annex whole counties?" ]	[ "> My very rough attempt at visualizing what a map of the universe might look like. There is no \"centre\" of the universe, \"where the big bang happened\". Rather, as we look at distant galaxies, we observe that every single one is moving away from us (on your map, some are moving towards us). The observation that...
what is the difference between a broken neck that causes death and one that causes paralysis?	[ "It depends where the injury is and how severe it is.

How do hand warmers work?	[ "The ELI5 answer is that they contain iron (and other things), and immediately begin to rust when you open the packages and they're exposed to air. The rusting process creates heat." ]	[ "They use a wavelength of light that is cancer causing. Do you want to sit under a cancer causing light? Plus, they aren't all that effective to stop, say a sneeze from transmitting to another person. It takes some time to kill the germs." ]

Unfortunately for them though the economy wasn't handled correctly and they quickly became over populated and/or people moved on from them." ]	[ "Becaus for most if them their frontal lobes aren’t developed yet and are very easily molded by repetition and hype. Adults have the ability and experience to see the BS in ads." ]
[Physics] Is it possible that the information in the brain survives death? Sean Carroll says we know and understand every particle/force/field that could interact with the brain. As a result, if this information were being carried away after death, we could detect it.	[ "I've thought about this quite a bit, and Carroll is absolutely right in saying that if there is an effect carrying away information - which obeys the laws we are used to - then we would be able to detect it. The problem is that if you really want to believe in god or the afterlife or whatever, then you can just s...	[ "in short, no, the pattern will not change.
