How long was magic considered a viable topic of political discussion and consent in England?
As a brief note in advance: witch trials in Europe did not *begin* until the 15th century, and not in earnest until the 16th! You can find various parts of the witch stereotype well in action before then, but they are used to identify and condemn heretics, not Satan-worshipping, magic-practicing witches. That said: F...
[ "The early modern period saw significant social change in Great Britain in terms of the position of individuals in society and the growing power of Parliament in relation to the monarch. In the 17th century, there was renewed interest in Magna Carta. English common law judge Sir Edward Coke revived the idea of righ...
why do noises become louder the more tired i am?
Attention to a task requires mental energy to filter out unimportant information that's coming in from ones surroundings. Consider the phenomenon of turning down the music in the car when you are trying to figure out where you are. Excessive, distracting stimuli can overwhelm the brain and make it harder to concentrate...
[ "At the very least, noise may be annoying or displeasing or may disrupt the activity or balance of human or animal life, increasing levels of aggression, hypertension and stress. In the extreme, excessive levels or periods of noise can have long-term negative health effects such as hearing loss, tinnitus, sleep dis...
why don't we use counties as congressional districts?
Because many states have a lot more counties than congressional districts, especially in the East. Illinois has about 100 counties, and 18 congressional districts.
[ "Senate district lines are drawn with an eye toward adhering to the boundaries of the state's 14 counties, and the districts are named after the county or counties in which the bulk of the district is located. However, due to equal representation requirements of the federal and state constitutions, most districts d...
how to minimise personal injury if inside an elevator in freefall!
Lie on top of a fat person. You're falling at the same speed as the elevator, so jumping makes no difference.
[ "A dangerous variant of shafting involves entering elevator shafts, either to ride on the top of the elevators, or to explore the shaft itself. This activity is sometimes called elevator surfing. The elevator is first switched to \"manual\" mode, before boarding or exiting, and back to \"automatic\" mode after, to ...
what did old computers even do?
The first (fully electronic) computers were used to produce "firing tables" used by artillery. These are tables that say "if you are here, and the enemy is over there, and they are 20 meters higher than you, and the wind is blowing that direction at 5 m/s, then aim your gun like this to hit the enemy". Before computers...
[ "The personal computer has been around since approximately 1976. But in that time, numerous technological revolutions have left generations of obsolete computing equipment on the junk heap. Nevertheless, in that time, these otherwise useless computers have spawned a sub-culture of vintage computer collectors, who o...
How accurate are the costumes traditionally used in productions of Les Miserables?
Some of them are fairly decent. Some, not so much. One thing I'll note across the board is that the women never seem to wear corsetry, which affects their overall silhouettes - particularly in the earlier scenes, where the waistline and bust were still quite high. [**Fantine**](_URL_1_) The first thing I have to ment...
[ "Illustrator Alan Lee served as the film's conceptual designer. Despite heavy fantasy elements, the production is historically accurate to a degree, in keeping with the probable origins of the Arthurian legend in Sub-Roman Britain.

whats going on between tumblr and 4chan?
Tumblr is filled with SJWs (Social justice warriors). 4chan is filled with trolls. I dunno who fired the first shot, but the basic gist of it is that there are two communities of similar hateful personalities with polar opposite political and social beliefs going at it.
[ "Tumblr (stylized as tumblr and pronounced \"tumbler\") is a microblogging and social networking website founded by David Karp in 2007 and owned by Verizon Media. The service allows users to post multimedia and other content to a short-form blog. Users can follow other users' blogs. Bloggers can also make their blo...
hey eli5: how are opals formed?
It starts with a space in a rock. This can be a crack, or a void left after something organic was trapped in sediment and rotted away. Ground water carrying minerals flows through the rock, and the minerals are deposited. If they are the right minerals, you'll get opal.
[ "Opal is a hydrated amorphous form of silica (SiO·\"n\"HO); its water content may range from 3 to 21% by weight, but is usually between 6 and 10%. Because of its amorphous character, it is classed as a mineraloid, unlike crystalline forms of silica, which are classed as minerals. It is deposited at a relatively low...
why do i yawn when i have motion sickness?
your brain thinks something is wrong and tries to flood your bloodstream with oxygen to relieve itself.
[ "Yawning is considered a non-respiratory gas movement. A non-respiratory gas movement is another process that moves air in and out of the lungs that don't include breathing. Yawning is a reflex that tends to disrupt the normal breathing rhythm and is believed to be contagious as well. The reason why we yawn is unkn...
how can bill gates give away roughly $28bn since 2007, which has lead to 6 million lives being saved, but we see these adverts on tv, like from unicef, which ask for donations of less than 50 cents a day to help save the lives of children?
Those 50-cent donations are about meeting basic needs like food, and they are short-term solutions. Once you eat 50 cents worth of food, it's gone. Gates and other big donors are investing in long-term projects like public health programs and vaccines. These won't help immediately, but once they do, they will be hel...

does having a clean car really help with gas mileage? if so how?
Clean vs slightly dirty, then no. Clean vs covered in mud after going off-roaring, very slightly. Air resistance is an important factor, and with a clean and waxed car, there is less resistance than a car covered in mud, but it won't result in a noticeable difference (less than 0.1 mpg).
[ "\" Gasoline is the main expense of the cars, practically on a weekly basis, or even more frequently if we use the car very often, we will have to go to our nearest gas station to refuel and make the consequent cost\".\n", "In late 2004, Norm Sterling, who was the Environment Minister in the Progressive Conservat...
What are the main historical records/accounts of Jewish enslavement and release/exodus from Egypt?
Would like to add to OP's question: BESIDES THE BIBLE/TALMUD, since that tends to be the only source people use to refer to the event. From what I've gathered researching this independently there is absolutely no physical evidence of Jewish enslavement in Egypt besides the less than credible evidence from scripture. ...
[ "The story of the Exodus from Egypt, as related in the Torah, has shaped the Jewish people throughout history. Briefly outlined, the story recounts the experience of the Israelites under Egyptian enslavement, God's promise to redeem them from slavery, God's punishment of the Egyptians, and the Israelite redemption ...
I run a current through a solenoid and get a magnetic force. I stick an iron core in the solenoid and get a bigger magnetic force. How is conservation of energy preserved?
If you were to put volt/amp meter on that wire you would see the phase between the two values change as the iron went into magnetic saturation. This phase shift is called ‘reactance’, and is analogue to the electrical energy transferred to the iron core.
[ "To prevent eddy currents, which cause energy losses, the iron core is made of a bundle of parallel iron wires, individually coated with shellac to insulate them electrically. The eddy currents, which flow in loops in the core perpendicular to the magnetic axis, are blocked by the layers of insulation. The ends of ...
first principles
Usually when we design something, there is a tendency to have preconceived notions of how it is to be constructed. Music, for example, we think in terms of keys, chords, melody, then verse, chorus, refrain etc. Or a car, we may think 4 wheels, 1 engine, transmission, steering the front wheels etc. To start from fir...

Why is it when Metal/Rock is heated it usually glows a bright red? What about the rock getting hotter is making it produce light, Where is the energy coming from?
It's called [black body radiation](_URL_0_). Basically, atoms/molecules in the substance are constantly getting so hot that they get into a higher, unstable energy state. They spontaneously fall back down to their "happy" stable state. When they fall from a high to a low energy state, they release energy in the form ...
[ "Of course, the visual sensation usually associated with the metal gold is its metallic shine. This cannot be reproduced by a simple solid color, because the shiny effect is due to the material's reflective brightness varying with the surface's angle to the light source.\n", "In materials engineering and metallur...
why do bicycle helmets have holes?
Sweat. On a bicycle you are presumably exercising. With a fully closed helmet it would get uncomfortably hot and wet under the helmet as you are trying to shed the heat you generate by sweating. The bicycle helmet allows lots of air to reach your head so your sweat can evaporate properly.
[ "Since more advanced helmets began being used in the Tour de France, carbon fiber inserts are often used to increase strength and protection of the helmet. The Giro Atmos and Ionos, as well as the Bell Alchera, were among the first to use carbon fiber.\n", "Bicycle helmets can reduce injury in the event of a coll...
the stanford prison experiment (lucifer effect) and what it says about our society?
Frankly? Nothing. The Stanford Prison Experiment has been met with widespread criticism and controversy on several layers of its design and evidence, and is an experiment now frequently placed in the category of "Interesting, but that's about it". The experiment is the only one of its kind (maybe due to ethical concern...

How does a computer upscale 480p images and movies to 1080p?
Imagine that you have a matrix, where each element of the matrix is a pixel (this is essentially how pictures are stored on a computer). To make an image bigger, we take its representative matrix and make it larger, keeping all the original pixels in relative correct order (i.e., if we double this matrix, two pixels th...

Is hemp as great as some say it could be?
If it is so great, shouldn't the parts of the world where it's legal be enjoying this miracle crop and laughing at us?
[ "European experts on hemp, like Dr. Hayo M.G. van der Werf, author of the doctoral thesis \"Crop physiology of fibre hemp\" (1994), and Dr. Ivan Bûcsa criticized Herer for making unrealistic claims regarding the potential of hemp, compare L.H.Dewey (1943).\n", "The national (non-psychoactive) hemp market was $600...
why aren't people convicted of a crime even if they confess?
A confession is rarely enough evidence in itself to convict, the defendent must be proven guilty beyond a reasonable doubt. False confessions do get made, _URL_0_, and because of this, they are not in themselves enough evidence to convict. If the "strong evidence" along with the confession doesn't convince the jury be...
[ "Many confessions have involved the admittance of a crime that the dying has committed, which obviously cannot be prosecuted once the perpetrator has died. On the other hand, someone can confess that they have knowledge of or witnessed a crime that has been committed. This special kind of confession can sometimes b...
How large of an impact did the drowning of Frederick I (Barbarossa) have on the outcome of the third crusade?

why are women generally more close and intimate to other women than men to men?
They don't tend to be more close. But they do tend to be more affectionate. Men in Western Culture are trained to rarely display emotions. We are allowed to show anger, and to some extent excitement but most emotions have to be limited or hidden entirely. When it comes to affection you are allowed to show it with you...
[ "Consequently, men grow up to have a more autonomous sense of self, and to be more independent, more instrumental and competitive in their dealings with others. They are also more likely to have difficulty expressing their emotions and to be anxious about intimacy. Women, on the other hand, have more ability and mo...
How do these "3D" representaions explain 4D objects?
I'm not sure what you mean by "explain", but let me say something about these pictures. Suppose that you look at an image of a cube. Say, [this one](_URL_1_).

However, when assessing a patient who is already taking drugs, a doctor should always consider the development of any new signs and symptoms as a...
What is the origin of Rohingyas and how are they different from other Muslim ethnics(Kamans) of the Rakhine state?
[Here's my answer earlier today to the question "How Accurate is the Claim that the Rohingya are 'Bengali' and not Burmese?"](_URL_1_) > The claim that Rohingyas are Bengalis is true insofar as the Rohingyas ultimately derive from Bengal, but in the end it's a justification for genocide.

They describe themselves as descendants of Arab traders who settled in the region many generations ago. However, French scholar Jac...
Is there a genetic reason some can handle cold weather more than others or is it all mental?
Some adaptation mechanisms can make cold weather more tolerable. Lots of adipose tissue is one, high metabolism another, and low blood pressure a third. Low blood pressure makes for efficient peripheral circulation, resulting in warm hands and feet until, eventually, your core temperature drops and you crash.
[ "There are many factors which influence the strength of the response. People who live or regularly work in cold environments show an increased response. Through acclimatization tropical residents can develop an increased response which is indistinguishable from arctic residents. The role of genetic factors is not c...
What would happen if you passed High Voltage through water under pressure high enough to prevent the formation of gaseous water?
Here's a phase [diagram of water](_URL_0_) Assuming you did not just heat it to a high enough temperature to create a plasma, what you would get is a supercritical fluid.

If we took a snapshot of the positions of all planets, moons, and trackable asteroids in the solar system, how long would it take for them to make their way back to this initial snapshot?
To any kind of reasonable precision, they wouldn't ever return to that state again. In order for two objects to return back to their original positions, the ratio of the times it them takes to complete their orbits needs to be a rational number. For example, let's say we consider the Earth with an orbit time of 1 yea...

In the 1800s, if two monarchs met, how would they address eachother?
I cannot speak to meeting, but I can speak to the fact that in written interactions, a monarch addresses fellow monarchs as "sister" or brother", due to a concept that all monarchs are members of the same family, so a letter would be addressed to, "Sir My Brother" or "Madam My Sister". If they are actually related, ...

How to derive the Relativistic Doppler shift in Energy?
The easiest way is simply to apply the Lorentz transformations to the four-momentum of a photon. For any four-vector A^(μ), the Lorentz transformations for a boost in the x-direction say: A^(0)' = γ(A^(0) - βA^(1)), A^(1)' = γ(A^(1) - βA^(0)), A^(2)' = A^(2), A^(3)' = A^(3). With β = v/c, and γ = (1-β^(2))^(-1/2)...
[ "A more precise confirmation of the relativistic Doppler effect was achieved by the Mössbauer rotor experiments. From a source in the middle of a rotating disk, gamma rays are sent to an absorber at the rim (in some variations this scheme was reversed), and a stationary counter was placed beyond the absorber. Accor...
Why can European Colonialism be seen as an earlier form of globalisation?
Globalization refers to the international exchange of ideas, products, and cultures. There is something going both ways when we talk about globalization. Globalization is a much more equal exchange of cultures than colonialism was. Colonialism is basically just taking one culture, and transplanting it into a new locati...

why do we use wax instead of rubber to seal toilets to the floor drain?
Toilet flanges are often really uneven, especially when on a concrete floor. You need the wax to compress a LOT usually. It will squish as much as a half inch, and it won't put any upward force on the toilet. If you tried to compress rubber that much, you'd need to tighten the bolts on the toilet too much and it wou...
[ "Many types of toilets without a water seal (also called dry toilets or \"non-flush toilets\") exist. These types of toilets do not use water as an odor seal or to move excreta along. For example, from simple to more complex: a bucket toilet (honey bucket), a tree bog or arborloo (two simple systems for converting ...
What program was used to read the first computer code? What code was that program using?
An important concept here is to make sure that you think about a computer program as a set of instructions. It's like a recipe or a script- a list of things to do in a certain sequence. A program doesn't do anything by itself, just like a recipe doesn't cook dinner (as much as I wish it would...) The computer hardware...

When did shortening names into nicknames become common?
Examples I can think of from Antiquity include "Yosi" from "Yoseph" (Joseph) and "Yeshua" from "Yehoshua" (Joshua), from which "Jesus" is derived. Note that often, that would be someone's given name, but it was given to them as a shortening of an existing name.
