Post something Weird or Random

It has bothered me that women get cool looking shoes like these yet the shoes men are forced to wear are ugly and boring unless you spend hundreds of dollars for those colorful and/or patterned sneakers and high tops that are only available from fashion designers. Meanwhile women can get cheetah print heels for $50 in some stores.

Here is another random thing, since I posted a cartoon about pi.
.
For units of Newtons / kilograms, g (the average acceleration due to gravity on earth) =~ pi squared.
.
This is because the meter is defined as the length of a simple pendulum which has a period of 1 second. This has to do with both gravity and circular motion, thus g and pi are related.
.
(edit) btw, a simple pendulum vs a real life pendulum is a physics abstraction whereby all the mass of the pendulum is on the very end, furthest from the fulcrum. So, the string has no mass.

If that is the definition of a meter, the arbitragers must be having lots of fun shipping things sold by their length to low-gravity areas like Hudson's Bay

Haha, well assuming sea level, I guess. And it is one potential definition of a meter, the math does check out.
.
(edit) for pendulum motion, T = 2*pi*sqrt(L/g)
.
For L = 1, and a full period of 2 seconds (the 1 second is half period, I was off a little)
.
2s = 2*pi*sqrt(L/g) --> 1s / pi^2 = (1s) * g --> 1 = g/pi^2.
.
The L=1 is called a meter.

>>again, not sure if this is the only definition of meter, or if it is actually how it was established. But it does work.

Local gravity varies more by the density of the underlying rocks and the latitude than the altitude. Back to the trivia: The two satellites chasing each other around the Earth to chart those anomalies are called Tom and Jerry.

ok, average gravity as defined by g, roughly 9.8 meters / second^2. The variances due to altitude or local density are really fairly trivial for the Standards and Units people.
.
Speaking of trivial, the satellite names are cool

haha, ok since I got sidetracked into physics and units, here's a fun physics joke.
.
A farmer has a problem with one of his cows, and asks a physicist for help. The physicist thinks about the problem for a few days and comes back to the farmer, and says "first you take a homogenous spherical cow..."

I accidentally sent a picture of my butt to everyone in my address book. It cost me a fortune in stamps.
