Interesting Facts

This has got to be bull****.

There's so many sleep studies, that I can actually see a fact like this being determined (unlike some of the other facts, where there's really no way to be sure whether they're true or not). I usually fall asleep within 5 minutes, though I have no idea if this fact is true.

So they were related, but not in a way that caused them to have a common last name. That's odd, I never realized that.

Teddy and FDR were related. FDR and Eleanor were married despite being 5th cousins.
 
Just remembered this one.

The color code to make truly invisible text here at CZ is f7f7ff.
It will only be revealed when highlighted or quoted. Additionally, you have to manually type the color tag to use it.
 
Fact: Black is not a color, it's the complete absents of color.
Fact: White *IS* a color, it's all colors.

When all colors of paint are mixed together it does not turn white. It turns black.

I'm guessing it has something to do with some type of refraction cancellation. Sort of like noise canceling headphones use destructive interference.
 
If you pour liquor on a scorpion,it will drive it crazy and it will sting itself to death.
 
  1. Moonshine is called that because it was made "by the light of the moon". (didn't have to tell BP that I bet! :) )
  2. At the equator the earth spins at 1,038 mph
  3. The speed of the earth as it circles around the sun is 67,062 mph.
  4. Astronomers think the Milky Way (our galaxy) is traveling at around 1,342,161 mph relative to the locations of other galaxies.
 
For the original "Halloween" movie, Michael Myers' mask was actually a slightly modified and painted white mask of William Shatner that the production designer purchased over the counter for $1.98.
 
The band that played in the final moments of the Titanic were not considered members of the crew, as such their families received no compensation for their deaths. In fact, someone went as far as to send violinist Jock Humes' father a bill for $3.90 for the loss of his uniform.

I wonder if the field of Public Relations was created swiftly after the fact.
 
If you hold your thumb up towards the sun, about 100 billion neutrinos will pass through your thumbnail every second.

You don't have to hold it towards the sun for that to happen. :laugh2:

The Neutrino is a subatomic particle famous for its ability to slip through matter without interacting. Neutrinos have none of the "handles" by which most other particles affect one another: no electric charge, almost zero mass. They are so elusive that a light-year of lead, nine and one-half trillion kilometres (six trillion miles) would only stop half of the neutrinos flying through it. The only hope for detecting them is to put a large quantity of matter in one place and hope the occasional neutrino will, by dumb luck, strike an atom somewhere and interact with it. Because so many other radiation sources are releasing energy throughout the Universe, any detector trying to spot neutrinos has to deal with backgroud noise. Picking the signal out of this noise can be a challenge. To make the problem easier, neutrino detectors are built underground, often within deep mineshafts. The rock around the detector blocks any radiation not powerful enough to penetrate beneath the Earth; because neutrinos are so "slippery", they can pass through the rock and reach the detector device.​

I know, just putting that out there so a person would have a frame of reference and so I didn't have to mention densities and power and stuff like that.
 
On a side note, one of the High-Energy faculy here at Tech is obsessed with the detection of neutrinos. When I took the particle physics class with him, we spent a lot of time on the subject. In nyc's post, his citation mentions how "slippery" the neutrinos are, that is the truth. A big problem to overcome is that the neutrino just doesn't interact with anything. Also the electron neutrino has such a negligible mass (which in itself is hard to measure) it is difficult to determine how much momentum it has, which affects the amount of momentum transferred in the detecting device.

How many pass through if you hold your thumb up Uranus?
