Mind blowing. Almost makes me want to take physical chemistry again. Almost.

Incredible.

Quote:
A careful reading of official Major League Baseball Rule 6.08(b) suggests that in this situation, the batter would be considered "hit by pitch", and would be eligible to advance to first base.

From the Short Answer Section:

Quote:
When my wife and I started dating she invited me over for dinner at one time. Her kitchen had something called Bauhaus chairs, which are full of holes, approx 5-6 millimeters in diameter in both back and seat. During this lovely dinner I was forced to liberate a small portion of wind and was relieved that I managed to do so very discretely. Only to find that the chair I sat on converted the successful silence into a perfect, and loud, flute note. We were both (luckily) amazed and surprised and I have often wondered what the odds are for something like that happening. We kept the chairs for five years but despite laborious attempts it couldn't be reproduced.

—R. D.

This ... isn’t actually a question.


But thank you for sharing!

Only read the baseball one in the link. Why does a baseball moving that fast cause what is essentially a nuclear explosion??? I think i have a grasp on it but not sure...

1) Baseball is moving so fast that it is splitting the atoms and molecules in the air?
2) Assuming 1 is true, the resultant atom splitting causes a nuclear reaction?

Where do the Gamma Rays come in?

Gamma rays are released during the interaction of nuclei (fission/fusion) and through good, old-fashioned radioactive decay. What they are saying is that the ball would be moving so fast that the air molecules (O2, CO2, N2, etc) would fuse with the molecules on the surface of the ball, each fusion giving off a burst of gamma rays. This would essentially create an expanding bubble of superheated gasses as the escaping gamma rays trigger more nuclear fusion. The comic is actually saying that throwing a ball at that speed creates a chain reaction similar to what you see in stars...only on a much smaller scale, and not sustainable because of a lack of matter (that's why it goes off like a nuke instead of forming a "star").

And, btw, XKCD is the absolute ****. It's the geek equivalent to internet rule 34.

Interesting one today: "If a meteor made out of diamond and 100 feet in diameter was traveling at the speed of light and hit the earth, what would happen to it?”

You could always jump over to the web-comic section. 1100+ of those.

Interesting one this week - cost of pennies:
http://what-if.xkcd.com/22/

I've always wondered if I should leave my change in the car when mountain climbing, just for this reason.

Some interesting mish-mash this week:

http://what-if.xkcd.com/23/

In particular, I like the response to the bomb/hurricane question.

And that the Internet is smaller than an oil tanker.
