As others have said, both American and British English accents have changed since the time of colonization. However, American English more closely resembles the language as it was spoken. It is documented that the British aristocracy adopted an accen... |
Why are cryptocurrencies (e.g. BitShares) able to increase by ~250% in 48 hours while the rest of technology stocks fall drastically? | Because the increase in value of a cryptocurrency is based on speculation to try and turn a short term profit. As soon as some plurality of investors get cold feet, everyone sells and the value plummets. The number of investors willing to engage with that kind of risk is relatively small, so each investor has a more si... |
How do search engines work? Where are they searching from? | So first you need an index. Pick a website, and make a note of all the terms on that website.

As for why humanoid robots specifically, having a robot with human for wo... |
Why does my head "hurt" while learning something new and complex? | I believe this is because you're building new neural pathways. You feel a physical sensation when an existing neuron makes a new connection. Various pathways give you various ways to access that information might refresh you, a certain scent, another word, something seemingly random like the name of a rock band you hap... |
The Fed Interest Rate Decision/Possible Hike | Somebody will come in here and put me to shame, but here is my understanding. Interest rates are kept artificially low to promote borrowing and lending. Essentially promoting movement in the economic cycle during hard economic times. The rates can't stay low forever.Hopefully we can change this back to *un*solved? Ther... |
Why does a computer with a 32bit operating system max out at 4GB of RAM? | 2 to the 32nd power is about 4.2 billion, so that's the number of bytes that can be addressed. In a 64 bit computer, 2 to the 64th power is a lot more, so for the foreseeable future, that's more than enough addressing capability. |
Why are companies obligated to follow through with incorrectly priced orders? | They're not obligated to--they cannot undo transactions that are complete, but they can alter or refuse a deal before that point. However, customers tend to appreciate it a lot when a company errs in their favor; it's a public relations choice to do so. Also think of how many companies issue refunds when they're not re... |

How did ISIS obtain all those fully armored (sans guns but bulletproof) American Humvees? | We gave weapons and trucks to the Iraqi army. A lot of the Iraqi army are Shia, which is the same religious sub-sect as ISIS.

Why does music sound so much worse on an AM radio station than on an FM radio station? | FM broadcasts are limited to 15 kHz audio bandwidth and occupy a 200 kHz channel. AM broadcasts are limited to 5 kHz audio bandwidth and occupy a 10kHz channel. Also, FM sounds better because it is less prone to interference and fading from weak signals.AM radio waves are bigger and longer. This means they can travel f... |
Why aren't we trying to create settlements on the moon first before we try settlements on Mars? | Some people believe the moon isn't worth it. Gravity too low, fewer resources, no atmosphere. Mars is way more appealing. The only big problem is that Mars is really far away. But once you get as far as the moon, it isn't that much harder to just keep going to Mars. |

How can water be wasted if it is a renewable resource? | If you use groundwater faster than it replenishes, then water table lowers, wells dry up, trees die. Just because something is renewable doesn't mean you can't use it all up. You need to use it at a rate lower than it is renewed. _URL_1_ Edit: groundwater depletion can also cause the ground to sink. Mexico City has sun... |
Do fish need to drink? If so, how? | Freshwater fish absorb water through osmosis. It's the movement of a solution through something semi-porous, like skin, until the solution is equal and balanced on both sides. They do swallow water when they eat, but they don't "need" to drink. Saltwater fish also go through osmosis, but the concentration of salt in th... |

This is not fatal, so you're not going to die |
Why did Humans evolve to have consciousness? | It is a result of an extremely layered system of nerves. For example a very simple nerve would detect if a cell is moving left, a slightly more complex one would turn of the "move right muscles" when the move left signal is being received, to save energy. The brain is layers and layers of this type of thing, super syst... |
Why do humans like to sleep on soft surfaces such as memory foam? How does this fit into survival? | Lol memory foam is a bad example, we used to sleep on gathered leaves. Most animals prefer to sleep on soft things because hard, uneven surfaces will press into us and cause pain. Animals often still lie on flat hard surfaces because their fur cushions it, but humans are just skin with various prominent bones poking at... |
Why doesn't your stomach digest itself? | It continuously produces mucus to prevent this.

To compost efficiently, you grind leftover food or unused animal products up, make ... |
How does mouth to mouth resuscitation work when the giver of air is breathing out CO2? | The lungs don't absorb all the oxygen when you inhale, so when you exhale, there's still lots of oxygen in the breath. IIRC, it's about 60% of what you breath in? Now sure, this isn't optimal. One of the first things medical staff do with a seriously ill patient is whack him on oxygen. But the theory behind Expired Air... |
How did people figure out how to domesticate yeast thousands of years before germ theory? | They didn't. At first they just knew that if you leave out fruit and wheat juice and come back later, it has alcohol in it. The alcohol then was generally kind of nasty. And bread did this weird rising thing.

Does training in harsh environmental conditions (hot,cold,rain) make it more or less effective? | It allows you to become more comfortable in those conditions. If you experience hot, cold or wet a lot, you learn it's not so big a deal and how to prepare for it. Then you're not worrying about being hot, cold or wet. You're worried about running. One exception is high altitude. If the air is thinner, you get less oxy... |
How does surveying work, and what's with the telescope? | The 'telescope' is a device called a theodolite. By using a theodolite and looking at the multi-coloured stick, you can tell how much the ground has risen or fallen between the two.There are a couple of ways to do surveying, but in the past, they have been based on "triangulation". If you remember all that geometry fro... |
What’s a manifold? | It's an object like, say, a klein bottle, which has the property: for any point on the object, you can examine the area around that point, and that area will have the same basic topology as **R**^n . For a Klein bottle- even though the bottle itself has weird stuff going on- little pieces of it are basically just ordin... |
Why is Africa so far behind all other counties in development and technology? | Aha! I just read a theory on the subject.

Why do you call black people "African American", and also, why then don't you call white people "European American"? | African American was an invented term meant to be comparable to Italian American or German American. But most African Americans living in the United States don't know their exact country of origin, because their ancestors came across as slaves, and they had lost connection with their prior ancestors. Further, many of t... |
Why exactly do flashing lights cause epileptics to have seizures? | It's a common misconception that all people with epilepsy have seizures when they see flashing lights. This form of epilepsy is uncommon. In fact, some patients can have seizures in response to other forms of stimulation, such as rhythmic noises, or in some cases even unmoving visual patterns. In most such cases, the k... |
Why does skin still burn when contacted with heat AFTER it's been damaged by heat? | The burning pain sensation that follows after skin is burned is caused by the undamaged nerves in the surrounding skin, or the nerves in the burned skin if it isn't too damaged. Cold helps numb the nerves in the skin, which alleviates some of the pain sensation. |
The U.S.'s strong desire to make Iran the bad guy. | The geopolitics orbiting Iran are complicated. It's a combination of conservative war-hawking at a strong islamic republic, responding to constant baiting from the government of Iran, the potential for Iran to actually have nuclear weapons and the desire to keep Israel happy but not happy enough to start a war. America... |
When one looks through a telescope, whether an earthbound amateur or the Hubble, what exactly is happening? Are you seeing further or seeing bigger? | You can only see light that has reached you. The lenses in telescopes magnify a small area of your field of view onto a large sensor, giving you an image of something that was otherwise indistinguishable. |
Why are AMD processors SO MUCH cheaper than iNTEL Processors? | Because core count isn't nearly as important as marketing would have you believe. Even the clock speed isn't a 100% reliable way to see which CPU is better. If you want to compare AMD and Intel CPUs in the same pricerange, google their benchmarks in various games. That'll give you a more accurate reading of how they co... |
How do nations such as Finland afford to supply university education for free? | Some European countries are starting to twig to the idea of "the public good," and beginning to realize what was obvious to some all along: it benefits society in general.

Doctors and food experts of Reddit; Hot and spicy food, can it burn your insides? | Not at all, no. The "hot" sensation that comes from spicy foods is kind of the chemical equivalent of an optical illusion.

So it hurts, but in a way ... |
When lightning hits the ocean or a lake, why isn't everyone in it shocked? | Lightning is an electrical current between the clouds and the ground, and like all electrical currents it tries to take the path of least resistance. Fresh water is a very poor conductor and humans are a significantly better conductor, meaning that if lightning hits water and is trying to reach the ground the "shortest... |
Why do planes have to go so high if there isn't anything going on 2 or 3 thousand feet up? | Many reasons. Jet engines operate most efficiently at higher altitudes, which means you use less fuel, which makes flying cheaper. If there is an emergency it is best to have as much altitude as possible underneath you, you have longer to sort out the problem or decide what to do while you are gliding. Also, ever lived... |
why does petrol in america only contain 87 octane where as in england it contains minimum 95? (where i live) | The octane rating of a fuel measures how much compression the fuel can withstand before igniting.

One method yields the Research Octane Number , w... |
NAD+, NADH, FAD, and FADH2 | NAD and FAD are proton transporters in biological systems. Nadh is NAD carrying protons, Fadh is fad carrying protons. Nad works with enzymes to take protons from CH-OH groups to make a C=O group. FAD does the same with CH2-CH2 groups to form CH=CH groups. At least that is how I understood it. I'm a food science major ... |
I just blew my nose and my contact lens fell out. How? | There is a duct for draining tears from your eye that travels to your sinuses. It's possible to pressurise your sinuses and blow air back up that duct - which can dislodge your contact lens. |
how can telescopes capture close up pictures of planets without any obstructions in the picture? Wouldn't you be able to spot out debris such as meteorites and such? | Do you mean "why don't we see stuff in the way between us and the planet"? If so, it's because those objects are much, much too small to be seen by telescope at the distances we're talking about. In principle, we could see them, but they're just too small to disrupt the picture at all. |
In UNIX/Linux, what's the difference between X, X11, Xorg, XWindows, XSession and XServer? | In 1984, some people at MIT created the X Windows System , a system for displaying multiple programs together on Unix and Unix-like systems. This windowing system was designed to work over the network, so it has a client and a server. If you run ssh with the -X flag, you can run graphical programs on the remote machine... |
Why do some planes leave a visible stream in the sky while others don't? | It's simply a matter of the air temperature at the specific location and altitude of the plane, because that will determine whether it forms condensation trails. The same plane that you see not leaving a trail may leave one half an hour later as it moves into air with different conditions.Contrails are the result of wa... |
How is it that water is used a lubricant, but if my feet are the tiniest bit wet, putting on socks becomes incomprehensiby hard? | Water is not used as a lubricant.

Modern digital cable TV system complicate some of the deta... |
Today I watched a tail amputation. I was completely fine in surgery, but as soon as I walked out of surgery, I nearly fainted. Why is that? | It probably has something to do with adrenaline. While watching the surgery, your body was, no doubt, tense and on edge. Your brain saw the surgery as a threat. "Could this happen to me?", etc. Once the surgery was over, your body could relax and your fight or flight response wore off because you were in a "safe" envir... |
Why do rappers like to name drop cities in their music? | if your from there you relate and buy their musicI don't listen to much rap, but the impression I get from what I *do* listen to is that rap/hip-hop songs are heavily influenced by the artists\' past experiences . Because of this, things such as city names, past events, fellow artists\' names, etc, are often explicitly... |
what happens inside my brain and body when I feel my mood 'drop' instantly because I have depression? | Me too!

That is the best I can come up with based on what I've noticed with my depression. |
Why do public toilets have the front of the seat missing, but home toilets have the full seat? | As a Plumber - the Open Front Toilet Seats are required by Health and Sanitary Codes for any Public Restrooms.

How does a computer scale images to different aspect ratios? | There are two types of images, raster graphics and vector graphics. Vector graphics rely on mathematically produced 'paths' to draw the image. When rescaling the image, the computer simply recalculates the path and there is no quality loss. Raster graphics rely on pixels. When these are scaled, the computer uses an alg... |
Why can a human be treated for rabies after they've been bitten, but when a dog is bitten it's too late? | Some vaccines/treatments/etc only work if they are applied before the body is exposed to the disease.

Deflation was rampant during the Great Depression. Why didn't the U.S. Government just pump lots of money into the economy like they are doing now to combat the Great Recession? | Our understanding of fiscal/monetary policy was not nearly as developed as it is today. There was not really even accurate GDP measurement back then. It was not until the Great Depression, and Roosevelt doing some pretty intense experimenting with policy , that we were able to further enhance our practical understandin... |
As a foreigner, what would happen if I took out a loan to purchase a property in Greece after they defaulted on their debt and changed to Drachma? | There's a joke about economists: > A philosopher is visiting his friend in the economics wing of the university.
