how does more expensive shipping take longer? | "One-day shipping" means that it will take one day from the time the package is sent to the time you receive it. There's no guarantee that the package will be sent immediately - it might take a few days for them to get around to your order.
"Expedited" means they move your order to the front of the line but it doesn'... | [
"A shipping method is by evaluating three factors: time, cost, and product characteristics. While shipping by sea could take longer than shipping by air, the latter is generally more expensive. Shipping by rail could also be complemented by piggybacking the freight onto a truck so it can be delivered to the receive... |
Does having glasses on/off affect the clarity of psychedelic hallucinations? | No. CEVs do not involve the eyes. OEVs will be altered if vision is impaired. | [
"The cited resemblance of the imagery to LSD- and psilocybin-induced hallucinations is suggestive of a functional resemblance between artificial neural networks and particular layers of the visual cortex.\n",
"Drug-induced hallucinations are caused by hallucinogens, dissociatives, deliriants including many drugs ... |
circumcision | This is one of those subjects that has been discussed ad naseum. I'll try to hit the highlights.
Pros:
Possible health benefits (this one is the biggest debate)
Aesthetics
Cons:
The idea that the child should be the one to choose
Claims of loss of sensation/physical pleasure.

"Although there is some debate within Islam over whether it is a religious requirement, circumcision (called \"khitan\") is practiced nearly universally by Muslim males. Islam bases its practice of circumcision on the Genesis 17 narrative, the same Biblical chapter referred to by Jews. The procedure is not explicit... |
My phone has a barometer which can tell me the pressure of the surrounding air. What can I infer from this information? Can it give me some information I can use in day to day life? | Barometric pressure is commonly used to measure elevation, as air pressure changes with elevation. One caveat is that air pressure also changes with weather, so elevation measurements incur error as conditions move from nominal. For greater accuracy you can recalibrate your elevation at a known location (e.g. sea level... | [
"A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.\n... |
speculative bubbles | So lets say you're at lunch, and someone has some new cookies you have never had before. You trade him your apple for the cookies. The next day, he and another friend have more of these cookies, and they trade them away and you get more cookies. All of a sudden your other friends in school hear about these cookies, and... | [
"Speculation is often associated with economic bubbles. A bubble occurs when the price for an asset exceeds its intrinsic value by a significant margin, although not all bubbles occur due to speculation. Speculative bubbles are characterized by rapid market expansion driven by word-of-mouth feedback loops, as initi... |
Will seasons change calendar months throughout Earth's axial precession cycle? | If we did not do calendar adjustments in the intervening time this would eventually happen. However we do adjust the calendar in order to keep our months and seasons in sync.
The Romans had this problem with their 355 day calendar and 22-23 days added ever 2-3 years. Unfortunately the process to add those extra days ... | [
"Over thousands of years, the Earth's axial tilt and orbital eccentricity vary (see Milankovitch cycles). The equinoxes and solstices move westward relative to the stars while the perihelion and aphelion move eastward. Thus, ten thousand years from now Earth's northern winter will occur at aphelion and northern sum... |
when people get a decent amount of sleep, they don't taste their morning breath. however, if they get very little sleep, this taste lingers throughout their day. why is this? | Bad breath in the morning is sometimes caused by your mouth drying out if you sleep with it open. Sleeping with your mouth open is sometimes a symptom of sleep apnea or blocked sinuses, which lead to lower quality sleep. So, basically it's not that you don't notice your bad breath if you sleep well, but rather that bad... | [
"The intensity of bad breath may differ during the day, due to eating certain foods (such as garlic, onions, meat, fish, and cheese), smoking, and alcohol consumption. Since the mouth is exposed to less oxygen and is inactive during the night, the odor is usually worse upon awakening (\"morning breath\"). Bad breat... |
Flash Freezing the planet | You could probably gather some information from _URL_0_
Although nothing to do with a giant barrier, the premise is the same but dust blocking the suns energy. | [
"On June 19, 2008 (sol ), NASA announced that dice-sized clumps of bright material in the \"Dodo-Goldilocks\" trench dug by the robotic arm had vaporized over the course of four days, strongly implying that they were composed of water ice which sublimed following exposure. While dry ice also sublimes, under the con... |
why is the zimbabwean dollar worthless? | The government of Zimbabwe owed a lot of people a lot of money. They thought that they could get out of debt by just printing more money. This caused massive **inflation** - the reduction in value of a currency due to an increased supply.
People frequently post questions here asking why the government can't just pri... | [
"Zimbabwe also suffered from a crippling inflation rate, as the Reserve Bank of Zimbabwe had a policy of printing money to satisfy government debt. This policy caused the inflation rate to increase from 32% in 1998 to 11,200,000% in 2007. Monetary aid by the International Monetary Fund was suspended due to the Zimb... |
what causes a lazy eye, and what is the perspective of someone who has one? | I think it's a muscle issue in the eye where one side of the muscle is pulling too much or too little. I'm not sure exactly. But i had it when I was a kid. For me it was like having double vision constantly, coupled with farsightedness. It improved a lot since I was a kid (virtually non existent these days) but for the... | [
"Lazy eye, in particular strabismus may be the result of coordination between the extraocular muscles, which prevents a person on directing both eyes in unison towards the same fixation point. The main cause of strabismus is usually the muscular imbalance of the six surrounding muscles that allow both eyes to focus... |
if america has so many problems in iraq - why don't they just leave ? | Warhawks control the country. War is good for business. It's good for 24 hour news, it's good for the military, it's good for defense contractors, it's good for the state. | [
"Because of the importance of Iraq, the potential for catastrophe, and the role and commitments of the United States in initiating events that have led to the current situation, we believe it would be wrong for the United States to abandon the country through a precipitate withdrawal of troops and support. A premat... |
why do lightning bolts sometimes break into segments before disappearing? | Lightning is just the transfer of built up electricity from one place to another. Sometimes, it's strong enough to reach the ground. Other times, it can dissapate into nearby clouds before reaching the ground.
So if you see it flash, but not hit the ground, that basically means there were two clouds near each othe... | [
"Trees can explode when struck by lightning. The strong electric current is carried mostly by the water-conducting sapwood below the bark, heating it up and boiling the water. The pressure of the steam can make the trunk burst. This happens especially with trees whose trunks are already dying or rotting. The more u... |
When a black hole eventually "evaporates" does it reach a point where light can escape it? Or does it just stay looking like a black hole right until it disappears? | Basically it will exist as a black hole up to the smallest a black hole can maintain it's event horizon as a singularity (approximately 228 metric tons compressed to smaller then the wavelength of a photon). at which point it will release the remaining energy in a blinding explosion of light roughly equivalent to 5 mil... | [
"A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of t... |
How did Cortes' army fight off Native Americans that outnumbered them hundreds to one? | You might be interested in u/anthropology_nerd 's great entries on the "[Handful of Adventurers](_URL_0_)" myth, and especially on the "[Invisible Allies](_URL_1_)" myth.
For a very short answer: First thing to keep in mind is that Díaz had a specific purpose when writing. He (like other conquistadors) had felt slight... | [
"Cortés was able to pacify the country, after the indigenous realized the Spaniards put \"an end to the rape and robbery that the Mexicans practised.\" Finally, Xicotencatl the Elder, baptized as Don Lorenzo de Vargas, agreed to support Cortés's expedition against Texcoco. According to Bernal Diaz, he sent more tha... |
How credible are claims about mass starvation, torture and killing of Germans in internment camps after WW 2, as claimed by books like "Other Losses" by James Bacque or "An Eye For an Eye" by John Sack? | You can find 'Other Losses' addressed [here](_URL_0_), which should hopefully be a good start for you. | [
"In \"Other Losses\" (1989), Bacque claimed that Allied Supreme Commander Dwight Eisenhower's policies caused the death of 790,000 German captives in internment camps through disease, starvation and cold from 1944 to 1949. In similar French camps some 250,000 more are said to have perished. The International Commit... |
Most important lessons from Rome (help a teacher out!) | Here are two ideas which came to mind.
1) **Roman openness and inclusion**
Rome was an unusually open society for the ancient world. From the very legendary beginnings Romulus opened an asylum and accepted all comers to his new city. Later Rome gave citizenship to deserving foreigners, whether Greek, Gaul, African, S... | [
"The Romans had learned many things which we are now learning again, such as green manuring with legumes, soiling, seed selection, the testing of soil for sourness, intensive cultivation of a fallow as well as of a crop, conservative rotation, the importance of livestock In a system of general farming, the preserva... |
"bulking" in fitness, what is it? what is the science behind it? | There are two types of bulking; clean and dirty.
A bulk involves packing on muscle mass and fat as part of a training regime. One cannot gain lean muscle mass, without a fat gain, it's simply impossible. Even if the fat gain is negligible.
People bulk for two main reasons: jump up a weight class, and look bigger. The... | [
"The general strategy adopted by most present-day competitive bodybuilders is to make muscle gains for most of the year (known as the \"off-season\") and, approximately 12–14 weeks from competition, lose a maximum of body fat (referred to as \"cutting\") while preserving as much muscular mass as possible. The bulki... |
What are dictators for, were they always frowned upon, what was their original purpose, and has there ever been dictators that did “a good job.”? | I'll give you a brief answer on at least the origins of the term.
The first dictators were from ancient Rome. It was a position that went with the standard consuls, quaestors, praetors, etc. However, the dictator was apart from those positions. Dictators were a special position only put into power during times of grea... | [
"Some dictators have been masters of crowd manipulation, such as Mussolini and Hitler. Others were more prosaic speakers, such as Stalin and Franco. Typically the dictator's people seize control of all media, censor or destroy the opposition, and give strong doses of propaganda daily, often built around a cult of p... |
Paper or Foam cups? | This is a great example of [greenwashing](_URL_1_). The text implies that the styrofoam cup is more environmentally friendly (less solid waste is good, right??) but ignores the myriad other issues that make the paper cup the more eco-friendly choice of the two.
And this is a great chance to talk about one of the co... | [
"The manufacture of paper usually requires inorganic chemicals and creates water effluents. Paper cups may consume more non-renewable resources than cups made of polystyrene foam (whose only significant effluent is pentane).\n",
"The manufacturing of paper cups contributes to water pollution when chemicals such a... |
how can i tell where a sound is coming from if it all travels the same route to the same place? | The "pinnae" which is the visible part of the ear is not symmetric front to back. The sound bounces differently off the ear and into the ear canal, and your brain can detect the difference and translate it into direction. If you attach a different prosthetic ear or damage your existing ear there is a period of time whe... | [
"Sound does not usually come from a single source: in real situations, sounds from multiple sources and directions are superimposed as they arrive at the ears. Hearing involves the computationally complex task of separating out the sources of interest, often estimating their distance and direction as well as identi... |
Do sound frequencies from more than one source stack to result in a greater (louder) sound? | Two sound sources that are uncorrelated (such as two voices talking) do add to make physically "louder" sound. Let's say that there are two sources generating some sound pressure at the same time and are uncorrelated. If they are both producing sound at the same level, the superposition of the two sources result in a s... | [
"While a large loudspeaker is naturally more directional because of its large size, a source with equivalent directivity can be made by utilizing an array of traditional small loudspeakers, all driven together in-phase. Acoustically equal to a large speaker, this creates a larger source size compared to wavelength,... |
Why does the fusion of two hydrogen atoms release a positron and a neutrino? | The reaction you're referring to is:
p + p - > ^(2)He.
Helium-2 is an unbound resonance which immediately decays. Most of the time, the protons just slip apart and undo the fusion reaction which created it. But some small fraction of the time, ^(2)He can beta decay into ^(2)H. This beta decay involves changing a pro... | [
"Fusion takes place when atoms come into close proximity and the nuclear strong force pulls their nuclei together. Counteracting this process is the fact that the nuclei are all positively charged, and thus repel each other due to the electrostatic force. In order for fusion to occur, the nuclei must have enough en... |
when did writing your name in a fancy, semi-legible way come to be recognized as your signature? | Since almost forever. Rulers and lawmakers have always "legitimized" a law or contract by putting their symbol on it. Before everyone could read and write, signatures were often symbols such as crests. But most kings in England were literate and signed their legal documents. [Here's King John's signature from 1205]... | [
"From the initial assignment by Western music theorists of letter names to notes in the 9th century it became possible to reverse the procedure and assign notes to the letters of names. However, this does not seem to have become a recognized technique until the Baroque period. From the mid-19th century it has becom... |
Doping Semiconductors with both n and p type materials. | This is a rather interesting question.
Doping a silicon crystal with phosphorus atoms decreases the energy needed for an electron to reach the conduction band, which increases the conductivity of electrons. Also, doping a silicon crystal with boron atoms decreases the energy needed for a hole to reach the valence band... | [
"It is a wide-bandgap semiconductor of the II-VI semiconductor group (since zinc and selenium belong to the 12th and 16th groups of the periodic table, respectively). The material can be doped n-type doping with, for instance, halogen elements. P-type doping is more difficult, but can be achieved by introducing gal... |
Physicist entangles the spin of 2 particles, A and B. If Physicist measures Particle A and finds "spin up" -- but Particle B is left undisturbed -- does B remain in superposition until measured? Or has B's wavefunction collapsed to "spin down" simultaneously with the measuring of A? | It depends on the initial entangled state.
If you create a state
(|up > |down > + |down > |up > )/sqrt(2),
And you measure the first particle to be up, then the second particle is automatically in the state |down > , i.e. not in a superposition state in this basis. | [
"According to ordinary quantum theory, it is not possible to measure the spin or polarization of a particle directly; instead, the component in one direction is measured; the outcome from a single particle may be 1, meaning that the particle is aligned with the measuring apparatus, or −1, meaning that it is aligned... |
why will the world population peak at 9 billion? | Birth rate is declining globally, however the current population is living longer, so the people that are currently being born live longer than previous generations, so there are more people alive for longer leading to a temporary increase in the number of people on the planet. | [
"In 2000, the United Nations estimated that the world's population was growing at an annual rate of 1.14% (equivalent to around 75 million people), down from a peak of 88 million per year in 1989. By 2000, there were approximately ten times as many people on Earth as there had been in 1700. Globally, the population... |
why can't foods have both a best before date and use by date? | Well they could, but there are no regulations that force companies to do that. In fact there aren’t really any regulations towards the dates on products. The companies themselves choose those dates. Most, if not all, use those dates to determine when they think their product might not perform or taste the best. Even t... | [
"\"Best before\" or \"best by\" dates appear on a wide range of frozen, dried, tinned and other foods. These dates are only advisory and refer to the quality of the product, in contrast with \"use by\" dates, which indicate that the product may no longer be safe to consume after the specified date. Food kept after ... |
How old did people get in acient times? (Like the Roman Empire period) | There is evidence of people who made it to at least their 80s, such as Cato the Elder, who apparently lived to be 85 years old. However making it to this age was a LOT less common than it is these days. The average life expectancy in Rome was around 25, however this would have been brought down by a reasonably high inf... | [
"The average life expectancy in Ancient Rome at birth was 27 years old. Early deaths in women were common because of the dangers of childbirth and men often died on the battlefield. Those who lived to an elderly age expected their children to take care of them. In the second century AD, laws were passed stating a s... |
Who were 'bad guys' in WW1? | It is a shame you have so many downvotes, as it is a good question. I suspect everyone reacting so badly might think you mean the "bad guys" n an absolute sense; that there is some kind of moral right and moral wrong which the warring powers fit neatly into. As /u/Warluster so articulately pointed out, which side you b... | [
"The world's most notorious bad guys are invited to the island fortress of super-villain Tan-Gu (Lloyd Floyd) to compete in an Olympic-style tournament of evil, called the Evilympics.

warhammer 40k | Basically what makes it so costly is that Games Workshop, the company that produces it, has a monopoly on it. Since 40k is one of the oldest and most popular tabletop games, you basically have to buy from them if you want access to that player base. Add to that the fact that they change the rules and rebalance the armi... | [
"Warhammer 40,000: Rites of War is a turn-based strategy game based on the Panzer General 2 engine by SSI. It is set in the fictional \"Warhammer 40,000\" universe. It was produced by Games Workshop in 1999, and concerns the invasion of a Tyranid Hive fleet and the Eldar and Imperial efforts to defeat it. The game ... |
how do you remove gravity in a chamber? | Those aren't on Earth - they are airplanes in parabolic flight. Look up "vomit comet." | [

In devices that require multiple batteries (like say, an xbox controller) do both batteries lose same amount of charge over time? What would the battery-life expectancy be if I changed only one battery, when both old ones are dead? | In most cases you use multiple batteries to increase the total voltage to a level needed to get the needed work out of it. So for example, if you need a voltage of 4V you can stack up four 1V batteries in your circuit. For example, that's the main reason why the orientation of battery generally alternates, [as shown i... | [
"Nintendo claims the battery lasts a maximum of 10 hours under ideal conditions on a full four-hour charge. Battery life is affected by multiple factors including speaker volume, use of one or both screens, use of wireless connectivity, and use of backlight, which can be turned on or off in selected games such as \... |
how are ships stabilized in high waves? | Primarily, a heavy keel.
The more mass you an concentrate below the waterline, the more stable your craft.
Secondarily, keeping it pointed into the swell.
A boat pointed into the wave is much, much more stable than one getting broadsided. | [
"Add-on stability systems are designed to reduce the effects of waves and wind gusts. They do not increase a vessel's stability in calm seas. The International Maritime Organization International Convention on Load Lines does not cite active stability systems as a method of ensuring stability. The hull must be stab... |
car air recirculation | Cars are really leaky, and not at all airtight, so the effect is minimal when you're surrounded by smoke. There's a small filter for incoming air typically between the hood and windshield (by the wiper arms) that lets cabin air in and filters it (older cars may not have a filter)
So when you turn on recirculate, a door... | [
"A Brayton cycle that is driven in reverse, via net work input, and when air is the working fluid, is the gas refrigeration cycle or Bell Coleman cycle. Its purpose is to move heat, rather than produce work. This air-cooling technique is used widely in jet aircraft for air conditioning systems using bleed air tappe... |
If you shot a gun in a zero gravity, but normal atmosphere environment, how long would air resistance take to stop the bullet? | The nits being picked by mo_dingo are correct, but in terms of a physics question/problem I still think it is a good question. I would reword it like this:

with ice caps melting, ocean levels rising, and higher global temperatures, this theoretically would be a perfect storm for massive rainfall. why aren't we seeing an increase in precipitation within dry arid area's, instead of increased droughts worldwide? | Dry arid areas like north texas where we've gone from 10 years of drought to massive flooding in 6 months? | [
"Its cycles of growth and melting were a decisive influence on global climate during its existence. This is because it served to divert the jet stream southward, which would otherwise flow from the relatively warm Pacific Ocean through Montana and Minnesota. That gave the Southwestern United States, otherwise a des... |
I understand why planets orbit the sun, but what specifically caused them to start? | The planets were formed from the matter in a [protoplanetary disk](_URL_1_) that surrounded the sun billions of years ago shortly after it was formed. The disk itself was spinning around the sun, so the planets ended up in orbits as the matter coalesced.
To some extent, though, it's true that the matter of the protop... | [
"In 1749, Georges-Louis Leclerc, Comte de Buffon conceived the idea that the planets were formed when a comet collided with the Sun, sending matter out to form the planets. However, Laplace refuted this idea in 1796, showing that any planets formed in such a way would eventually crash into the Sun. Laplace felt tha... |
Was there any sort of resistance to Allied occupation of Axis powers after WWII? | In Germany there was a very ineffective behind the lines force of leftover Nazi diehards called (in English) the "Werewolves." It's not proven that they did anything at all though: (_URL_0_) | [
"Within nations occupied by the Axis powers in World War II, some citizens and organizations, prompted by nationalism, ethnic hatred, anti-communism, antisemitism, opportunism, self-defense, or often a combination, knowingly collaborated with the Axis Powers. Some of these collaborators committed war crimes, crimes... |
why are fingerprints used as authentication, although considered insecure? | 99.9% of hacking, attacks and other technology related crime are about one thing: as much money as possible for as little effort as possible. Fingerprint gathering takes time and work to attack ONE target, and that work must be repeated from scratch to attack the next. Or, you can setup a phishing site, send out a few ... | [
"Historically, fingerprints have been used as the most authoritative method of authentication, but court cases in the US and elsewhere have raised fundamental doubts about fingerprint reliability. Outside of the legal system as well, fingerprints have been shown to be easily spoofable, with British Telecom's top co... |
How are plants selectively bred/grown? | The same way: you collect pollen from a select few plants and then selectively pollinate certain plants (perhaps the same ones) with that pollen. The fertilized flowers will then produce seeds that you can use to grow new plants.
Apples are in a funny category of plants that produce offspring that is very different fr... | [

Sparta thus exhibited the military efficiency, the thorough organization and the patriotic sacrifice of the individual to the state characteristic of Nordics everywhere and exemplified in mode... |
why do kegel exercises have tremendous benefits when flexing a muscle like the bicep does not? | The simplest answer would just be that the kegel muscle is a much smaller muscle and therefore is effected much more by flexing than a larger muscle such as the bicep. If you think about it as well, when you lift weights you are essentially flexing your biceps with extra weights in your hands. However, in the case of t... | [

How is it possible for people to survive gunshots or penetrative trauma to the head/brain? | Different areas of the brain are responsible for different things, for example I believe the frontal lobe is responsible for emotions and similar things like that and the brain stem is responsible for basic bodily functions such as breathing. As long as the part of the brain responsible for keeping you alive is not ha... | [
"There are cases where a person that received major trauma to one side of the brain, such as a gunshot wound, has required a hemispherectomy and survived.

why do christians think the plain red cups at starbucks are anti-christian, when previous cups' reindeer and snowflakes and evergreens were nordic-germanic pagan symbols and not related to jesus in the first place? | You shouldn't go looking for logic in this red cup nonsense.
Not to mention that this is a very small *very* vocal minority who is complaining about this crap. | [
"In November 2015, Starbucks introduced solid red seasonal cups, unlike previous seasonal iterations that were decorated with winter or Christmas-oriented imagery (such as reindeer and ornaments), but no overtly religious symbols. The cup design was discussed extensively on social media, with some citing it as anot... |
Does the number of links in a chain affect the amount of pressure placed upon each individual link, while under tension? | No. The amount of stress experienced by links in a chain due to a given load is dependent on the size (and shape) of the links, not by the number of links. The load on the chain has to be carried individually by each link. Otherwise, if you had a long enough chain, you could hold an arbitrarily large load with an arb... | [
"Because the actual bond stress varies along the length of a bar anchored in a zone of tension, most international codes of specifications use the concept of development length rather than bond stress.

why are certain unit abbreviations capitalized (e.g. ml, db) but not others (e.g. cm)? | The SI convention is that only those unit symbols that abbreviate the name of a person start with a capital letter.
