Did you know? David Bowie first came to America in 1971 where he had arranged to meet several big names in the recording industry at a gala. He arrived at the gala wearing a wig and a ballroom gown with his guitar slung over his shoulder, went to the center of the room and spontaneously began to play “Space Oddity” for everyone present. How’s that for a first impression?
Did you know that the Arauco War lasted for more than 300 years and that the mapuche conflict is still ongoing... (And you thought the plains tribes were tough)
Did you know? The Indian Sepoy Rebellion of 1857 was quite literally started over a rifle. The Pattern 1853 Enfield was rumored to have used cartridges greased in either pig fat or beef tallow, a substance that the Muslim and Hindu soldiers (respectively) were not allowed to eat. This proved to be the proverbial 'straw that broke the camel's back' and led to a very bloody war for independence that ultimately failed. By the end of this rebellion, the British East India Company was nationalized by the British Crown and the British Indian Empire was formed.

Even if the author is silenced, the performance is stopped, the story will not end.
Whether it's a comedy or a tragedy, if there is cheering, the story will continue on.
Just like the many lives.
For the us who are still in it and still in the journey, send warm blessings.

Speaking of India, did you know that the "tonic" in a gin and tonic is a compound developed to fight malaria during the English occupation? This tonic has a sharp and bitter taste on its own, but mixed with alcohol provides a much more pleasing taste that made the required daily dose of the admixture (for the British who's immune systems were much more susceptible to the disease) go down much smoother.
Did you know? You couldn't write down a googolplex even if you tried! That's 1 followed by a googol zeroes (and a googol is 1 followed by 100 zeroes). Since an average book of 60 cubic inches can be printed with 5×10^5 zeroes, that's 8.3×10^3 zeroes per cubic inch. The observable universe contains about 6×10^83 cubic inches, so it could only hold 5.3×10^87 zeroes, far short of a googolplex.
In fact, even if you could write a zero on every elementary particle, you still wouldn't make it since there are only 2.5×10^89 particles out there!
This sounds even more tedious than what I saw in the music video for Brighter Than the Sun, where Colbie clips the grass in her lawn one blade at a time with garden shears...
Did you know? According to recent studies, teenagers have an inherent ability to determine the popularity of a song? Starting around puberty and lasting until the age of 18 or so, the teenage brain can instantly determine, within the span of 3 or 4 notes, not only how much they like a song, but can also determine with 96% accuracy whether or not their friends or others (including the young and adults) will also like the same song. Even though this information only came to light in 2009 (discovered by accident while conducting a study concerning the growth of music-study learning in teenagers), recording companies have greatly shifted their talent search departments to, essentially, a bunch of 14 year olds.
It's possible to do that?! I thought just identifying a song by three or four notes can be hard enough, but that...
They don't recognize the song, they just get, like, and impulse or something that lets them know if they'll like it, you know? The unfortunate part is that, with enough time, this means that record companies might (and I'll stress might) be able to boil it down to a set of 'most popular' themes and we'll get literal cookie-cutter music based solely off of what will sell best.
My professor in quantum mechanics told us about this the other day. Basically, the colors we perceive are the result of electronic transitions. And if you solve the energy levels of these transitions without considering relativistic effects, you get that gold should not look gold.
This is also the reason why mercury is a liquid and why your car starts every morning. Without relativistic effects the lead oxide battery in your car would not have enough oxidizing power to product the voltage necessary to start your car.
The human eye sees electromagnetic radiation with a wavelength near 600 nm as yellow...the reason for seeing it yellow is that it is absorbing all the radiation not necessary for yellow and reflecting those wavelengths necessary to see yellow at an observer.
The electronic transition responsible for this absorption is a transition from the 5d to the 6s level. An analogous transition occurs in Ag but the relativistic effects are lower in Ag so while the 4d experiences some expansion and the 5s some contraction, the 4d-5s distance in Ag is still much greater than the 5d-6s distance in Au because the relativistic effects in Ag are smaller than those in Au. Thus, nonrelativistic gold would be white. The relativistic effects are raising the 5d orbital and lowering the 6s orbital.
In laymen's terms, gold should appear the same color as silver, but because gold is heavier, its electrons travel at speeds closer to the speed of light and begin to experience changes due to relativity. Those changes alter the relative distances between the energy levels of electrons more than would be predicted by a basic understanding of electronic structure.
Edit: nath'd by LogicX. The root of the effect is that heavier atoms have more highly charged nuclei that exert a stronger inward pull on the electrons in orbit. To remain in orbit, the electrons must increase in speed. So the heavier the element, the faster its electrons are going, and the more pronounced the relativistic effects will be.
Very interesting. Why does it raise the 5d, but lower the 6s (relative to silver, I guess?) instead of raising or lowering both? In other words, why wouldn't both the s and d orbitals be affected by the greater pull in the same way?

Because the shapes of the orbitals are different. The s orbitals are all spherical and are centered around the nucleus. The d orbitals have multiple lobes that extend outward from the nucleus in different directions. Crudely speaking, you can think of the d orbitals as being "further away" from the nucleus than the s orbitals because they're stretched out in certain directions. When the pull from the nucleus increases, the effect is most pronounced on the s orbitals because they're the closest to the nucleus. This causes the s orbitals to shrink and pull closer to the nucleus. That puts more electron density closer to the nucleus, which screens some of the nuclear charge that the d orbitals (which are further away) can see, which makes them feel less pull, so they expand.
Imagine looking at something through fine mesh, like cheesecloth. If you fold the cheesecloth in half, you make it "more dense" and it becomes harder to see what you're looking at because less light is coming through. Same basic principle.

Not true. Chimpanzees also wage wars. Not quite sure about the enslaving, but I bet they'd be up for it!

I typed that without copy-paste. I hope I wasn't off by a factor of 10 (or even more)... I don't want to expand it farther than that though.
