why do so many otherwise great tv shows struggle to end their stories well? what is it about the creative/production process that makes this so difficult? | Simply put, it's easier to tell a 2 hour story than what amounts to an 80 hour story. With a 2 hour movie you spent 20 minutes introducing your characters, build your story a little and then spend 20 minutes ending it. If you've got 65 hours story building, it would feel very cheap to spend 20 minutes on ending it. ... | [
"Producer John Lloyd, speaking to \"The Times\" in 1989 hinted that it was the draining scripting and rehearsal process that led to the writers deciding not to make another series: \"Things do get very tense by the end of a series, because everyone involved in the thing is very clever, and very funny, and they all ... |
what legally defines "religious reasons?" | There is no uniform legal definition of "religious reasons," as you put it.
It sounds like you are asking about the effect that a person's religious beliefs may have in two different contexts: schooling and employment.
Under the 1st amendment, it is irrelevant whether one's religion is officially recognized. Accor... | [
"\"Religion has the meaning usually given to it but belief includes religious and philosophical beliefs including lack of belief (e.g. Atheism). Generally, a belief should affect your life choices or the way you live for it to be included in the definition.\n",

"The Holocaust (which roughly means \"burnt whole\") was the deliberate and systematic murder of millions of Jews and other \"unwanted\" during World War II by the Nazi regime in Germany. Several differing views exist regarding whether it was intended to occur from the war's beginning, or if the plans for it came a... |
how does military pay work? | Your pay is direct deposited like normal. You get paid biweekly and receive additional monthly payments. Line items such as "Imminent Danger," and there is another I forget. If there is a PX nearby you can purchase basic things there normally. You can also get some of your pay directly in cash from your units personnel... | [

How did Hitler fund such extravagant care for his armies in the beginning? (hugo boss uniforms, high pay for enlisted men, volkswagen cars, etc.) | A couple of remarks:
At that time, Hugo Boss was not a premium brand. His company manufactured work clothes and later various uniforms. Note that the uniforms were not designed by him, he was merely a manufacturer.
Volkswagen cars were supposed be be purchased with a savings plan, i. e. the customers basically had... | [
"Much of the party donations were used to pay off many of Hitler's private projects, such as the Berghof and Eagles Nest. He caused a minor controversy within leading elements of the party when he, in 1925, purchased a luxury Mercedes-Benz and a chauffeur to drive it for a total expenditure of 20,000 \"Reichsmark\"... |
Is holding pee in damaging or bad? Does it have different effects on women vs men? | You will increase your risk for a urinary tract infection if you delay peeing, since stasis will cause micro-organisms to multiply faster. Furthermore, some bacteria can actually attach themselves to the urothelium of your bladder. It's best to go right away if at all possible, since the "flushing" mechanism of emptyin... | [
"Stress urinary incontinence (SUI) is a common disease in women caused by pelvic floor muscle weakness. Coughing, laughing, sneezing, exercising or other movements that increase intra-abdominal pressure, and thus increase pressure on the bladder, are common reasons for urine loss.\n",

how does the pre-flight airplane check actually ensure that the plane is safe to get up in the air again, and what do the pilots check? | Electronics can fail in flight, and engines can also fail.
The key thing you need to understand it that you will not die if this happens. You probably won't even know about some failures.
This is because airplanes are engineered with resilience and redundancy. There is no one part on a plane that can fail and have ev... | [
"There are numerous systems on board an aircraft that must be set in the proper configuration to allow it to take off safely. Prior to every flight, the flight officers use checklists to verify that each of the many systems is operating and has been configured correctly. However, due to the inevitability of human e... |
why is it that when some light bulbs are recorded and played back in slow motion, they appear to be turning on and off really quickly? | Because they are. Incandescent bulbs are powered directly by passing a current through a filament. The current causes the filament to heat up and emit light. The power grid is A/C or alternating current. North America is 120 volts at 60Hz while Europe is 240 volts at 50Hz.
A/C power follows a sin wave. Power starts at... | [
"In the professional lighting industry, changes in intensity are called \"fades\" and can be \"fade up\" or \"fade down\".

Could Jews in Nazi-controlled territory convert to Christianity to avoid the holocaust, and how were they treated if they did? | Mentioning previous answers is intended to be a starting point, not to discourage more discussion. Follow-on questions, data, and debate is welcome.
I don't see a full answer, but the picture is moderately clear from the parts here.
As in "Did the Nazis treat Christian Jews differently?" at _URL_0_ , kieslowskifan p... | [
"The Nazi leadership seized on the idea of deporting the remaining German Jews overseas. Barren, unproductive lands were viewed as appropriate destinations as this would prevent the deportees from flourishing in their new location.

Outside of the Muslim world, it appears alcohol prohibition only occurred in N. America and Scandinavia, and only in the early to mid 1900s. Why did these nations totally prohibit alcohol at around the same time, and re allow it at around the same time? | I'll like to clarify that you are forgetting some states of India, where Prohibition has been in effect for over 50 years. Leaving aside the recent prohibition in Bihar & kerala (Because of 20 year rule), Several states such as Gujarat, Bombay Province, Andhra Pradesh, Tamil Nadu, Haryana have had prohibition at one ... | [

why do hurricanes have “eyes” where there is calmness? | [What goes up must come down](_URL_0_). Anything in weather is about a balance, and so as the cyclone produces violent upward motion in the form of thunderstorms, sinking motion has to happen somewhere else. Some air is dissipated outwardly at the highest altitudes but some of this sinking air approaches the center of ... | [
"Since hurricanes rely on sea surface temperature, sometimes an active season in the beginning becomes quiet later. This is because the hurricanes are so strong that they churn the waters and bring colder waters up from the deep. This creates an area of the sea the size of the hurricane, which has cooler waters, wh... |
how do the developers of free applications make money without microtransactions ? | Advertising is a large source of revenue. | [

What impact have HeLa cells made upon research into treatments for things like cancer and Polio? | Have you read this book yet? _URL_0_ I would start there. | [
"The ability to rapidly reproduce HeLa cells in a laboratory setting has led to many important breakthroughs in biomedical research. For example, by 1954, Jonas Salk was using HeLa cells in his research to develop the polio vaccine. To test his new vaccine, the cells were mass-produced in the first-ever cell produc... |
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 with... | [
"The sensor capturing the image can be moved in such a way as to counteract the motion of the camera, a technology often referred to as mechanical image stabilization. When the camera rotates, causing angular error, gyroscopes encode information to the actuator that moves the sensor. The sensor is moved to maintain... |
Why is there an abundance of spherical-shaped things that aren't under any pressure to be smooshed round by gravity? Are atoms, particles, etc. even necissarily spheres? | Well, let's be careful here. Let's assume that a nuclei happens to be ~octagonal~ octahedral: 4 nucleons in a square, 2 in the dips in that square. If I shoot an positron at the nucleus, how do I expect to find the two oriented? You don't know (without fields that would provide a preferred alignment)! So, over the cour... | [
"Similarly, spherical particles were used in early prototypes but were later substituted with cylindrical particles. This is mainly because cylindrical particles gain much more charge than spherical particles, as they stand on end when being charged. Given also that cylinders penetrate a liquid's surface more easil... |
why aren't carbon monoxide detectors on cars? | What would be the purpose of such a device? Cars which use an internal combustion engine release carbon monoxide when the engine is running. You don't need a monitor to detect that. And you already know not to run the car in an enclosed space because of that fact. | [
"There are several different sensors that can be installed to detect hazardous gases in a residence. Carbon monoxide is a very dangerous, but odorless, colorless gas, making it difficult for humans to detect. Carbon monoxide detectors can be purchased for around US$20–60. Many local jurisdictions in the United Stat... |
how do mathematicians come up with equations that describe natural phenomena? | They run experiments, collect datapoints and then try to come up with some maths that fits the data. | [
"In geometry, equations are used to describe geometric figures. As the equations that are considered, such as implicit equations or parametric equations, have infinitely many solutions, the objective is now different: instead of giving the solutions explicitly or counting them, which is impossible, one uses equatio... |
why a front facing camera flips the image it takes? | The image a camera takes of you is how you look to other people. The image you see in a mirror is the flipped one, but it is the one you're used to.
That's why people think they look weird in photographs - because their face in a photo is not one they normally recognise. | [
"Moving the front standard left or right from its normal position is called \"lens shift,\" or simply \"shift.\" This movement is similar to rise and fall, but moves the image horizontally rather than vertically. One use for shift is to remove the image of the camera from the final image when photographing a reflec... |

"In 1962, the first commercial superconducting wire, a niobium-titanium alloy, was developed by researchers at Westinghouse, allowing the construction of the first practical superconducting magnets. In the same year, Josephson made the important theoretical prediction that a supercurrent can flow between two pieces... |
where did all the soil come from? | TL;WR :: Erosion, Dissolution, and Poop
1. Gross mechanical processes turn large chunks into small chunks.
2. Chemical processes dissolve things, particularly water and such.

why were capitalism and communism so vehemently in opposition to the other in the cold war, and sought to subvert each other even if it sprung up in wildly different cultures and places? | Capitalist thought starts from the idea that a system that lets people keep all the wealth they produce will give the greatest overall wealth. They also believe that anyone willing to work in such a wealthy system would get enough to lead a good life.
Communists thought differently. They believed that a Capitalist sys... | [
"With the Revolutions of 1989 and the dissolution of the Soviet Union in 1991, most of the world's Communist governments were overthrown and the Cold War ended. Nevertheless, anti-communism remains an important intellectual element of many contemporary political movements and organized anti-communism is a factor in... |

How is it possible to determine the age of species (not organism) by sequencing its DNA? | You can estimate a [molecular clock](_URL_0_) from sequences of DNA using rates of mutation events. These may then be calibrated to fossil records to determine actual ages of nodes in a phylogenetic tree.
From this, you can calibrate divergence dates of species (or genera or higher), and these macroevolutionary event... | [
"This is where molecular dating can be useful. A rough estimate of the age of a lineage, and indeed genes, can be achieved by assuming that mutations accumulate at a constant rate in the genome. While the dates produced by this technique are often imprecise, and vary from method to method, the technique can provide... |

the difference between density and pressure | Density is how much of something there is in a certain volume.
Pressure is how much something want to move away from where it is.
They are related, especially when talking about ideal gases (double the density doubles the pressure), but pressure can change without the density changing, by increasing the temperature. | [
"Where γ is the weight density. Weight density may also be described as the pressure gradient because it directly determines how much extra pressure will be added by increasing depth of the column of fluid.\n",
"Since gas molecules can move freely within a container, their mass is normally characterized by densit... |
Does Daniel Gibson thesis regarding Petra as being "the Mecca" hold any validity nowadays ? | Not really. There are some historians (e.g. Patricia Crone, who I’m not sure how serious she was about the point or if she was just trying to be provocative) who have argued that the rise of Islam makes more sense in a north Arabian or southern Jordanian context thenthe central Hijaz location of Mecca.
This is a prett... | [
"In the \"Sharḥ al-Asāṭīr\", a commentary on the Samaritan midrashic chronology of the Patriarchs, of unknown date but probably composed in the tenth century C.E., it is claimed that Mecca was built by the sons of Nebaioth, the eldest son of Ishmael.\n",

Survivors, including some who lost homes, villages, and family members, were found likely to face mental health and physical challenges. Much of the stress came from lack... |
Is it possible to form metallic bonds between Uranium and Sodium? | Yes, there is nothing preventing alloy formation between low and high melting metals. You can even make alloys with mercury, which we call amalgams. There is apparently documented evidence that a sodium-uranium alloy exists, though I can't find any information on its properties. It's possible that the information is... | [
"Nickel-62 has the highest binding energy per nucleon of any isotope for any element, when including the electron shell in the calculation.

why aren’t older gaming consoles emulated on phones these days? new phones have powerful processors/displays and should be able to handle nes, snes, sega genesis, etc. right? | There are emulators out there, as well as emulators for early PC games. I'm not sure why you think there aren't. The reason the original companies don't make the games again is that it doesn't make much money. So you have to rely on community programmers instead. | [
"Because of the original device's backward compatibility with earlier Nintendo products players can enjoy a massive selection of older games on the console in addition to hundreds of newer Wii game titles. However, South Korean units lack GameCube backward compatibility. Also, the redesigned Wii Family Edition and ... |
Can one get heavy metal toxicity from drinking Goldschlager? | No, your digestive tract cannot process gold metal into the ionic form that would have the potential to cause problems. Gold is one of the noble metals, which are known for having exceptionally low reactivities in the metallic state.

Without a magnetic field, and presumably no North, how do you navigate on the surface of Mars? | Currently, navigating on Mars is limited to rovers, and most of them don't travel very fast, or very far in one day. In this case, "navigation" is really limited to local obstacle avoidance in order to get to a nearby location to perform some type of science test.
If you're talking about how a person would (theoretic... | [
"The inconsistent Mars magnetic field precludes the use of a compass for navigation, so it will use a solar tracker camera integrated to JPL's visual inertial navigation system. Some additional inputs might include gyros, visual odometry, tilt sensors, altimeter, and hazard detectors. It will use solar panels to re... |
can someone explain me how thermite can work in this scenario? | I'm a little confused about what your saying, but thermite doesn't explode. More like, it burns really violently, throwing off sparks and hot material all over. It would potentially ignite anything in the vicinity that could burn, but it wouldn't make anything blow up. | [
"Thermite () is a pyrotechnic composition of metal powder, which serves as fuel, and metal oxide. When ignited by heat, thermite undergoes an exothermic reduction-oxidation (redox) reaction. Most varieties are not explosive, but can create brief bursts of heat and high temperature in a small area. Its form of actio... |
how can solids keep its form if the atoms that make it up are constantly moving? | In a solid the atoms that make it up is not constantly moving. That is the difference between a solid and a liquid. The atoms are moving a bit but they will not move past each other and will therefore keep its general configuration. Some solids, especially pure metals, will allow you to mold the solid as you can move t... | [
"In a solid, constituent particles (ions, atoms, or molecules) are closely packed together. The forces between particles are so strong that the particles cannot move freely but can only vibrate. As a result, a solid has a stable, definite shape, and a definite volume. Solids can only change their shape by force, as... |
What caused the vast difference in perception of American troops and their homecomings after WWII and Korea when they were just 8 years apart? | The huge difference is the perception of how the war progressed. While initially, the Korean War seemed popular with the general public, the setbacks during late '50/51 and the stalemate it ended made the war seem inconclusive in comparison to WWII where there was a clear victory. The war in Korea was also very differe... | [
"At the outbreak of the Korean War in June 1950, the U.S. Army looked to expand its force again to prepare for major conflict.

From the perspective of someone falling into a supermassive black hole, wouldn't gravitational time dilation cause the universe to end (and the black hole to evaporate) before he/she reached the event horizon? If so, how can black holes ever accrete mass on finite time scales? | No, it wouldn't. From the faller's perspective, as it is explained in [this answer](_URL_0_), the only things they can see are in their past light cone at the moment of entering the event horizon, so he/she doesn't observe the end of the universe, and still reaches the singularity in finite proper time.

What was the American view of the 1848 European revolutions? Was the general population aware of the changes taking place in Europe at the time? | In general the US public would have been aware, and would have been supportive. After the 1848 revolutions, a significant number of German revolutionaries immigrated to the United States (where many, such as Carl Schurz, would play prominent roles in the union military and federal government during the US Civil war).... | [
"The Revolution of 1848 had major consequences for all of Europe: popular democratic revolts against authoritarian regimes broke out in Austria and Hungary, in the German Confederation and Prussia, and in the Italian States of Milan, Venice, Turin and Rome.
