How can Justin Bieber have been recorded saying the N-Word in 2008 and have nothing happen, but Paula Deen generates a scandal for having said it years ago?	[ "Wasn't Paula Deen's instance more than just using the n-word? She was accused of something from a former employee that went to court. She also confessed to wanting to essentially have a slave party. And she handled the public in a poor manner with failed apology attempts." ]	[ "Mate, you're going to need to come up with a better example. That JFK cover is from 2013, ahead of the 50th anniversary of his assassination, a time when folks were inclined to overlook JFK's flaws.

The Monarchy was reintroduced in 1660." ]	[ "We began moving to the metric system around 40-50 years ago. When I was a child, shops still used to show weights in imperial - but a European directive that shops need to sell in metric really sped up the transition. There are a couple of things which we still use imperial measurements for though. They are distan...
Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.	[ "Well kid, you remember the difference between nouns, verbs and adjectives, right?

If the emphasis in an Englis...
How safe can monosodium glutamate actually be if it's an excitotoxin?	[ "Lots of things are toxic in large quantities. The LD50 of MSG (the amount of a substance that needs to be consumed for a 50% chance of death in most subjects) is 15-18 g/kg of body weight; the LD50 of salt is around 3 g/kg. As a simple additive, you're more likely to die from acute salt ingestion. That's not to sa...	[ "It's called Magnetic Secure Transmission.

MST sends out a signal with the same-ish information that the terminal is looking for. It won't work ri...
Is Mars more like a "baby/early" Earth, or a dead Earth?	[ "There are a couple differences. Earth has large amounts of liquid water. Mars has some water, but it's mostly frozen at the polar caps. Also, Mars has no magnetosphere to protect it from solar wind which caused most of its atmosphere to be stripped away. It's less than %1 as dense as our atmosphere on Earth. There...

Why do some single random hairs grow freakishly long over a short period of time?	[ "Your post just reminded me to check on \"Harold\", the one lone hair on my Adam's apple that used to grow about an inch or more per year while the rest of my neck is virtually hairless. I used to pluck him all the time. He's still there, but his growth rate has been curtailed significantly since when I was young....

Why does my fuel gauge bounce around?	[ "It is because the gas is sloshing around in your tank, and in older cars they had a little float that went up and down with the gas, therefore when ye gas sloshes around the float goes up and down a bit. And that is the reason your gauge goes up and down." ]	[ "The density of water varies with temperature, and has its peak near 4 degrees. [graph](_URL_1_) So if I were to guess I'd say that your temperature probe was near the bottom, and since there was probably some uneven heating going on, the warmer water went to the bottom at the start, but as the tempereature rose ab...
How could George Lucas make so universally hated movies after making one of the most loved ones? Is he a good or bad director?	[ "The running theory is that Lucas is best when he has an ensemble of talented crew around him. For the original Star Wars movies, American Graffiti, Indiana Jones, et cetera, he was one of many voices that came together to make the film. For those, he was certainly the main voice, but he wasn't the only one. By th...

Where are all the Native American restaurants? Was such a thing ever popular in the US?	[ "To add on this if I'm allowed... what is an example of native American food. I know it likely varied by region. We all know the stereotypes of plain dwellers eating buffalo and the early settlers learning how to grow corn from the local natives. But does anyone know if there is any native cuisine?" ]	[ "Is there a specific region and time period you are interested in? If not, your question would break our \"poll type\" question rule." ]
Why can't the simple solar still principle be used on an industrial scale to desalinate seawater and fill reservoirs?	[ "The pools would have to be huge in order to have a useful output. In theory you could scale up the technology, but like solar power plants, a very large amount of surface area would be required to input enough energy into the system. In short, it is cheaper and easier to use traditional desalination plants." ]	[ "It's way, way, WAY, too expensive. The power plant alone would probably be more expensive than the entire lifetime cost of an average bulk carrier. Not to mention the insane mess of regulation that is involved with running a nuclear reactor. Basically, big ships run on bunker fuel, and bunker fuel is ludicrously...
How can we see through all the stuff in the air?	[ "Because what's considered \"high amounts\" of things in air is actually quite a tiny amount. For example, pollen count is measured in grains of pollen per cubic meter of air, and the websites that I see to track it have \"very high\" pollen levels at around 10. That's 10 grains of pollen per cubic meter. Hardly so...	[ "You've actually captured the of the idea behind [Aether theories](_URL_0_).

Why did the attack on Pearl Harbor "force" the americans into the war in Europe and not just against Japan?	[ "It didn't. It forced the United States into a war with Japan.

Why have there been so many noreasters this winter in the United States?	[ "More extreme weather is a predicted side effect of climate change. Increased average ocean temperatures bring about larger swings in seasonal temperatures and more water in the air than there usually is. This can cause more storms in both summer and winter. Its not a guaranteed effect, but it is an expected trend....	[ "A big part of it is where the sensors are. I'm in DC, but my understanding is that all of the weather reports are based on measurements being picked up at Dulles which is an airport a few miles into Virginia, away from the city." ]
Why are there more islands in the Pacific Ocean compared to the Atlantic Ocean? What causes this difference?	[ "There are several factors. Firstly, the pacific is obviously bigger so it's normal to expect more islands in it. Secondly, the Atlantic is growing (South America and Africa are moving away from each other) so the newly formed ocean bottom as this happens is at the bottom of the ocean. Some places in the Pacific ar...	[ "They probably didn't.

The only reason they would do it is if the law demanded it and the gov was going to pay to costs of it." ]
How can arteries have higher pressure than veins?	[ "Veins have wider lumen, which is the hole in the vessel, and thinner walls. This means that even though it's under less pressure it contains more blood so it returns to the heart at the same rate." ]	[ "One big reason is map design. No road that goes north is straight. They are all designed to be curvy. This gives the impression that the map is larger because it takes longer to traverse." ]
Why do we use round bullets instead of sharp ones	[ "If you Google image search bullets you will see there are many different shapes and sizes with different purposes and characteristics. In short, there are sharp ones, round ones , big ones , small ones, hollow ones and so on." ]	[ "Our ancestors when in the wild would enjoy a fresh kill, body still warm.

Are electricity and magnetism related in a similar way that space and time are related?	[ "I would encourage you to watch [this video](_URL_4_) because it explains that relativistic effects, combined with the electric force, result in what we describe using a \"magnetic field\" and \"electric field\".
