Secular Humanism vs. Humanism vs. Atheism	[ "Atheism is simply believing gods don't exist. It makes no statement what you should do about it. Humanism is the belief in the betterment of mankind, as opposed to attaining some spiritual goal. Mother Theresa, for example, as not a humanist, as she was more concerned with getting people into heaven than helping t...

What are the most famous historical documents that are now considered as pure fabrication?	[ "The Protocols of the Elders of Zion may not be the most famous fabrication, but it perhaps led to the most harm. It was an anti-semetic propaganda book that contained the \"leaked secret plan\" of Jewish leaders to take over the world by manipulating the rise and fall of world powers for millennia. It fed into the...	[ "> how it really amounts to a bunch of bologna I don't have an answer, but I do need to point out that bologna = lunch meat. Baloney = nonsense." ]
Why is every naturally grown fruit round shaped? Why not piramid, or cube shaped?	[ "I'm going to make a somewhat educated guess here. It's probably because they all grow outwards at the same rate. If a fruit were cube shaped, it wouldn't have made sense for the corners to grow more/faster than the faces. Also, bananas." ]	[ "On top of promotions and \"volume in stock\", there is another possibility. Another factor may be how the item is expected to be consumed. You might eat an apple every day, so you would buy a big bag without counting them. When they run out, another bag. The store fills a hundred bags all the same size every day a...
Would our location be viewed as a nebula to distant galactic civilizations?	[ "Yep. The speed of light is the limiting factor here. When a photon is emitted from a distant galaxy, it will travel however many million/billion light years to arrive here, and also take however many million/billion years before it enters the optics of the telescope, so what we see is most certainly a 'view into t...	[ "I'm not sure if it would. this is one of the great questions of consciousness. I presume if we were still \"alive\" in any sense of the word, we would be in a dream-like hallucinogenic state. The brain creates images where there are none." ]
Why do some websites restrict the use of certain symbols and length of passwords?	[ "Depending on how they store the passwords, some symbols are \"reserved characters\". This means they have some special meaning to the software or database that's storing them and they can break the software if they are used. As to the length, I can think of a few technical reason why they would restrict it, but no...

Why have people freaked out so much that Valve+Bethesda wanted to take 75% of mod revenue, but not that Valve takes 30% from an indie game that someone entirely made themselves?	[ "Honestly, part of it is mass hysteria (we all love to conform in someway) and part of it is this is the first time a lot of otherwise ignorant people have stopped and thought about the fairness of how Steam (and any online publishing company - looking at you, Google) goes abouts its business. Is 30% worth the publ...	[ "Let's say your computer is a line of students (programs) in primary school waiting to be served lunch (processing resources).

If we witnessed a meteor hit the moon, would it be instant like on earth or would it be slower?	[ "I'm not sure what you mean about \"real time\" and \"slowed down\". We would see it over one second later because of the speed of light. The fastest known comet moves at 536 km/s, which is 0.1% of the speed of light. At these speeds you can observe color (and electromagnetic wavelength/frequency) shifts if you stu...	[ "You've discovered [the twin paradox](_URL_0_). The answer is that you can't have the spaceships \"suddenly\" be at rest with each other. Either one or both must undergo acceleration.

What is the consensus on Wernher von Braun? Brilliant scientist who "joined" the Nazi's in order the continue his research or Actual Nazi that should have been convicted of war crimes.	[ "I'd just point out that those two descriptions are by no means exclusive." ]	[ "Any soldiers who served in both Vietnam and WWII would have been field grade or higher officers, or senior NCOs. As far as I'm aware, there are no available numbers for men who served in both wars, but the army has kept track of three-time Combat Infantryman Badge awardees, almost all of whom saw combat in WWII, K...

In this game you are all in different rooms, one in the bedroom, one in the kitchen and so on - the only rule is you can't leave the room you're in. You play the game by shouting messages from one room to the other, and it's all fun. But there's a prob...	[ "This CGP Grey video does a really good job of explaining it all. _URL_3_" ]
Why is it a legal requirement to wear a seatbelt in a car but not on buses, trains etc.?	[ "Buses are larger and the passengers inside are much safer than they would be in a Sedan. A bus doesn't get thrown around in an accident much like a small car would - So the passengers wouldn't be thrown around much either." ]	[ "Some animals have bacteria harmful to us in their tissue before they are killed. These animals have to be cooked before eaten. Most notably, this includes chicken. Any ground meat can be contaminated in the grinding process, and must be cooked.

Other than customization, what exactly does Android excel in over iPhone and iOS?	[ "I would say the key things are android's integration with google software, although Apple recently developed their own cloud and whatnot google still has better maps, docs, etc. Another thing is memory, you have to pay a lot more for a 64 gig iphone and there is no expandable storage. Then there's the removable ba...	[ "Unit conversion is easier. Metric is all 1:1 and 10:1 conversions while ye olde Imperial is pretty random and obtuse. Otherwise the two systems are functionally identical for most common measurement purposes." ]
Did Europeans outside of the vikings have knowledge of the Americas before Columbus?	[ "People back in mainland Europe definitely heard about Vinland and fairly soon after the Norse showed up there. The earliest written account of the discovery of Vinland is actually from a German source, The Deeds of the Bishops of Hamburg written by Adam of Bremen and published in 1075 - two centuries before the Vi...

How do video cameras shift the focus from one thing to another so seamlessly/accurately?	[ "Part of the setup for shooting a scene involves blocking, where the actors are guided to the places they will move to throughout the scene. These are often marked with tape on the floor. The camera operator has an assistant who pulls focus. During blocking they will track the exact points of focus and mark it wit...	[ "random chance and recognizing false patters. How many faces do your eyes shift to in a full room? 10? 20? A hundred? How often do you catch people's eyes just at the right time? Maybe once?

Why are diamagnetic substances weakly repelled by magnets?	[ "Because when a diamagnetic material is held in an external magnetic field, a magnetic field is induced inside the material which opposes the external field. See [this picture](_URL_0_)." ]	[ "Because water is fairly high density, and is difficult to displace. You need a material with very low density, like cotton candy." ]
Why the Airspeed record hasn't been broken in nearly 40 years?	[ "_URL_0_ About 3 times as fast as the SR-71." ]	[ "If you can accept my passing knowledge of the matter before someone more qualified shows up, it's in how digital cameras capture images. Rather than capturing a single giant frame like film cameras, they scan a frame progressively, line-by-line. This results in artifacts with fast-moving objects such as plane prop...
Due to Climate Change, How Long Before Some Places Are Uninhabitable Due to Temperature?	[ "There's no specific temperature at which a place becomes uninhabitable. Death Valley already exists--but it's a tourist attraction." ]	[ "Because there is a disconnect between people and science. The government will only change things that benefit them, or that there is enough public demand for that changing it would increase their chances of continued election. If the majority of voters either don't know or don't care about something, the governmen...
How are we able to make guesses and thoughts on what objects would look like in a 4th Dimension, if we cannot perceive it with our eyes?	[ "A square is two dimensional, and is made up of one dimensional objects - lines - enclosing a two dimensional space. A cube is three dimensional, and is made up of two dimensional objects - squares - enclosing a three dimensional space It stands to reason that a four dimensional cube would be made up of three dimen...	[ "You're actually modeling a spaceship going relativistic speeds (and at that rate of compression, pretty close to the speed of light), where time passes slow on the ship compared to on the earth. Your question is the same as \"if there was some means of instantaneous communication, what would the people on the ship...
If we have telescopes that can see galaxies far far away, why dont we have one that can look at the surface (ground level) of planets?	[ "The problem is the scattering of light, and the scale of things. You can see those distant galaxies. But those galaxies are literally thousands of light-years across. A typically large galaxy is believed to be approximately 100,000 light years across. Compare that to a quarter on the ground, you can see we aren't ...	[ "We can, just not yet. These cameras are the initial landing cameras to make sure it survived the landing. Later this week, the fancy dancey cameras will spring up and give us lovely, awesome (like, literally awe-inspiring) imagery. Although it's pretty awesome already in my opinion :)" ]
If there was an atmosphere that had a very significant concentration of methane (like Titan), would it be possible to have a "lighter" or matches there?	[ "Titan's atmosphere is mostly nitrogen (98.4%) and a little methane (1.4%). So if you had a lighter filled with oxidizer, you'd have to use a locally available puddle rather than the air itself." ]	[ "The biggest and hardest problem is how to take off from Mars again after you land. This is assuming that you've already figured out how to deliver several hundred times as much mass as we've moved to Mars in all exploration so far and keep humans alive in interplanetary space and on the Martian surface for years. ...
How don't they know where a 777 is when we have radar and GPS?	[ "Radar is land based so any aircraft beyond the radar's range is not tracked. GPS is a navigation for the plane. It is not a world wide locator for anything with a GPS device. Its a system the plane uses to find out where it is. The plane would then have to transmit that location to either a ground station or a orb...	[ "I gona mention 2 potentially viable arguments but that are quite a few 1: It takes technology to make technology. Its like an exponential growth that has taken a long time to build up. A modern example would be for our modern computers to work we had to figure out analog transistors and before that we had have to...
Pewdiepie. What's the appeal?	[ "I think for Pewdiepie, he's come up with a specific paradigm that fits with a large enough niche of people that it spreads. Hell, that montage just got a view out of me because I wanted to watch the trainwreck to see what exactly it was that was so extreme about that video having 72m views. Honestly, I don't belie...	[ "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." ]
How come dandelions only grow on lawns?	[ "There are plenty of dandelions in the wild, but they do best in disturbed habitats where biological succession has been reset. Think forest fires, windfalls, and lawns. You don't see as many outside of lawns because their seed dispersal works best for open areas where they can get blown to and they like lots of su...	[ "They don't. It's a marketing ~~lie~~ gimmick. I used to work for a company that did a similar thing by mail. New customers were supposed to sign up by a certain time for special rates but as a specific matter of policy we'd give those rates to anyone who mailed back the special offer." ]
Why can't a mathematician copyright his theorem, like a singer can copyright his song, and charge people who want to use it or sue anyone who uses it without his permission?	[ "Mathematicians copyright the papers they publish — but their equations merely describe facts about the natural world, which is, as a category, not copyrightable. Phone books can't be copyrighted, for instance. They can copyright a particular phrasing of a theorem, but any theorem is just like a recipe." ]	[ "This is akin to asking why we don't have a cure for mosquitos. After all, couldn't someone just analyze the smell and appearance of mosquitos, and then develop a micro robot that specifically targets them? The pathways you describe are active research pathways, so far as I know. But research is hard, and actually ...
How could the world eventually run out of water?	[ "As others have pointed out, the issue is potable water, and we are not \"running out\" but overtaxing the supply. Water, even when consumed or used for irrigation, does not magically disappear. Some of it gets stored in the tissues of living organisms, some trickles down into the water table, some evaporates and b...	[ "I no expert but since the oceans/large bodies of water help regulate temperature is assume we would have much colder winter Temps and much hotter summer Temps. also the drop in temperature at night would be much greater ( like how deserts while hot in the daytime can also be dangerously cold at night)." ]
Why are halogenated chemicals so dangerous to living organisms?	[ "They don't have to be. For example table salt is NaCl and it is actually necessary for staying alive. So is having some iodide around for thyroid hormones. Elemental halogens are nasty because they are very reactive and very electronegative. HCl is a strong acid and is actually harmful because of the H+ it makes, ...	[ "(some) mold can make you sick or kill you. House plants generally do not make people sick. That's a pretty big difference. It's like asking \"why is it okay to hide in a closet, but not a running fireplace\"" ]
what is happening when your foot or hand or other body part "falls asleep" and starts to feel weird? Also, when you start to feel back connection with that body part, why can it sometimes feel like small needles are pressing into it?	[ "When you put pressure on the nerves to a body part, then the nerves don't work so well. When the nerves don't work well, you can feel numbness, or pain, or pins and needles. These are like the nerve version of static." ]	[ "It's natural response to scratch when something like a sting happens as scratching helps getting the foreign object out (yes patiently removing it with tweezers is way more efficient but this is a hard-wired primal response) It feels better because now instead of all nerves projecting pain they transmit the feelin...
If we were to develop a new probe using current "state of the art" technologies, would it have any advantages over the Voyager craft in terms of greater longevity or scientific output?	[ "Newer space craft could be made smaller and lighter because of advances in electronics. They could be accelerated to higher speeds (like [New Horizons](_URL_2_) ) and go deeper into space, faster." ]	[ "They have. When you consider 9 years - > 14 that's a massive increase in life expectancy. Do you expect humans to be able to double their life expectancy? Of course not, however a 20-30% increase over a few hundred years to maximize our potential? Reasonable - and this is what we've seen with pets." ]
How do camera operators in golf games track golf balls? They seem impossible to track in real life	[ "You've been thinking about this after listening to the Rooster Teeth podcast right?" ]	[ "Followup question: Is it possible to use a gyroscope instead of the back rotor to keep the helicopter from beginning to rotate with the blades, or is that not a thing gyroscopes are able to do? ^^gyroscopes ^^are ^^basically ^^magic ^^to ^^me" ]
If in-breeding produces weak/deficient/deformed offspring, why doesn't asexual reproduction do the same?	[ "In breeding results in homozygosity (the same allele in both positions). This means that conditions which are autosomal recessive are brought to the fore where before there was enough genetic diversity for this not to happen. Asexual reproduction is just cloning - there's no genetic crossover - so the offspring a...	[ "It does. Basically there is one more than the apparent two frames of reference (that of each twin) that need to be taken into account. twin A on Earth (inertial frame) twin B traveling away (inertial frame) *twin B traveling back (undergoes acceleration and shifts frames) One twin undergoes the turnaround while...
[WWII] My grandfather was a tank commander in the battle of the bulge, and has always told my father that he was the first tank across the bridge at Remagen. Would anyone be able to find anything about his battalion?	[ "Shoot me a PM. I work with some folks at the U.S. Army Center of Military History. I may be able to put you in touch with someone who could help." ]	[ "Possibly the Church of Our Lady, more commonly known as St. Matthias Church, in Budapest. This church became a mosque after 1541, when the Turks captured Buda. When Budapest was liberated from the Turks in 1686, the church came under the control of the Jesuits, who made attempts to restore it (it had been badly da...
Where did the words "Left" and "Right" come from?	[ "The word \"right\" is thought to come from the Old English \"riht\", which meant straight, good or proper. This comes from the concept that the right hand was the correct hand. [Source](_URL_1_) Conversely, left, it is thought, comes from Old English \"lyft\"meaning weak. [Source](_URL_0_)" ]	[ "Okay, this question really interested me so I tried my google-fu. I can see why you didn't find anything; all the search results are about lateral specialization of the cerebral hemispheres. But I finally figured out that the technical term for this is decussation and the theory is that originally the neural cor...
what's so special about sea salt?	[ "The main thing is texture. The salt is flaky and in larger chunks, which gives you a different mouth-feel, as well as isolated pockets of saltiness vs. a consistent level of salt. Some people claim to be able to really taste the difference between sea salt and regular salt, but I'm skeptical that it's that big of ...	[ "All the other reasons people are giving are valid, but I think for the majority of people it's down to advertising, pretty packaging, and the idea that spending more will get you something that's better." ]
How popular was mead (honey wine) in the middle ages?	[ "You should wait until next weekend, when there will be an AMA on the subject. I'm sure you will get a very informed answer then." ]	[ "Also, an add-on to this, were there ever periods of time where eating medium rare pork/chicken were acceptable, or has it always historically been beef that was eaten medium rare?" ]
Heat of solution vs. heat of fusion	[ "Yes, there is. The heat of fusion of a substance is directly related to its lattice energy, which is the strength of the intermolecular or interionic interactions in the solid state. The lattice energy plays an important in calculating the heat of solution, and is one physical parameters used in the [Born-Haber c...

Between the 1900's and the 1950's, was it "normal" or socially acceptable for an unmarried man to move out of his parents house if he worked locally?	[ "/u/pipkin42 has written an awesome answer about the [history of men living in hotels](_URL_0_) in the late 19th-earlier 20th century--both practical aspects and the social significance of it." ]	[ "Is this a homework question? It says in our [rules](_URL_2_): Our users aren't here to do your homework for you, but they might be willing to help. Remember: AskHistorians helps those who help themselves. Don't just give us your essay/assignment topic and ask us for ideas. Do some research of your own, then come t...
how many hydrogen bombs exist and how do they work? Is it the same as a nuke?	[ "There are two ways to create a nuclear explosion: fission and fusion. Fission occurs when you take a heavy atom (plutonium and uranium are used in nuclear weapons) and split its nucleus. This process releases a huge amount of energy, in the form of an explosion in the case of a nuclear bomb. Fusion is the exact op...	[ "Think of a rare baseball card. If there's only 10 of them in existence, then everyone would want them and they would be willing to trade hundreds of chocolate bars for it. Now think if they printed 990 more of that rare baseball card. Now everyone has one, and no one is willing to trade a chocolate bar for it." ]
why do grades in school skip "E" and go straight to "F" as the lowest grade?	[ "The earliest usage of the letter grade system as we know it dates to the late 19th century, most notably at Mount Holyoke College, and it was in fact rated from A-E, and eventually A-F (inclusive of E), before E was eventually faded out as a rule. [Here's a nice article about it](_URL_0_). D was never initially in...	[ "Dates back to ancient Rome. In a lot of old languages, they hadn't invented the space or the period yet. Like just long unbroken strings of letters. So they started making the first letter of a word huge to indicate new paragraph. The tradition kept, and in the middle ages, they'd hand write/paint a huge fancy let...
What is the difference between 32-bit and 64-bit?	[ "The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system. _URL_0_ Basically a 64 bit computer can do tasks generally better than a 32 bit one...

Why aren't there many people researching Polywell reactors?	[ "Because it doesn't seem to work very well. Almost all of the sources for that article are news releases and news coverage, with very few peer-reviewed journals that actually document the results of their experiments. Unfortunately, this is the modus operandi for scammers, or those who just continue to believe in...

If a very small amount of milk drips down the edge of a cereal bowl, why does a ring of milk form around the entire bottom when the bowl is lifted? Shouldn’t it just be where the milk dripped?	[ "Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in ...	[ "The egg never falls too far from the nest.

Why do we see strange patterns when we push on our eyes when they are closed?	[ "There are nerves in your eyes which are especially sensitive to light. But that does not mean they will not respond to pressure. They will send signals to the brain which the other nerves will interpret as light." ]	[ "As some people have said here, it's a form of submission, same with when people hold out their hands with the palms facing upwards to show they are holding no weapons. And since almost every religion is based off of submitting to a higher power, it makes sense that people would prove that they are not dangerous to...
Would covering the roof of a building with a reflective shade material cool it by a noticeable amount?	[ "This would make a big difference on a sunny day.

How come I get extremely sleepy if the temperature is really hot or really cold?	[ "Because your body uses a lot of excess energy either way. If you are cold your body expends energy to warm itself. If you are hot the body expends energy to to activate cooling processes. Either way you are burning more energy than you normally would and thus need more rest." ]	[ "Our brains didn't evolve with cars in mind. They evolved with, like, being hunted by a jaguar (or whatever) in mind. So your brain doesn't know what to do with a car.

Why was the British Royal Ordinance 105mm L7 tank gun so revolutionary? Why did Germany, the US, Japan and Israel all licence the design for their homegrown tanks instead of designing their own tank guns?	[ "I wouldn't go so far as to call it revolutionary. It was simply a quite conventional piece of artillery with the required performance. High velocity,good accuracy and a fairly compact breech. What helped it stay in service for so long was the development of improved ammunition, particularly the fin stabilized sabo...

How exactly do people die when a plane crashes? Also, do they feel pain or is it instantaneous?	[ "Your question is too vague to be answered accurately.

If professional wrestling organizations like the WWE fake their matches, how does a wrestler win the tournaments and championships they hold? Is it predetermined and planned?	[ "Everything is predetermined and planned. Professional wrestling is a high-action soap opera with a lot of stunts." ]	[ "How exactly did labor markets (or whatever was in their place) function in the USSR?
