There are a few, but they're right near the Colorado and Wyoming borders; and they still managed to make a straight road all the way across without hitting any hills.

Huh? According to whitepages.com, there's tons of them. Not as many as in California, of course. :D

Now, wait a minute.

Who Will Be The Last To Switch To Metric: The USA Or Liberia ???
 

As are minutes, hours, days, and years. Maybe amperes?

I too was surprised at how accurately they were able to depict life in Nebraska.

Although cultures have used hours to denote the passage of time for hundreds of years, the "second" is considered to be a metric unit. I once asked one of my college professors why. He said because the International Bureau of Weights and Measures says so.

Of course, that organization is located in France. :p

It is also an English unit (foot-pound-second).

And the French don't define it, nature does. The second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.

Mbyron, Are you in the quality or metrology fields?

If that is the measurement of a second how could it have been scientifically defined prior to the 20th Century?

And why is that the measurement?

1. Prior to the development of chronometers capable of measuring microseconds, the sidereal second was sufficiently precise.

2. It matches a sidereal second pretty closely. If you're asking why cesium 133, I don't know the answer to that one. Sorry!

2 is easy. cesium 132 wasn't quite long enough, and cesium 134 was too long.

Finally something that makes sense in this silly thread. :p

Is that your standard response to coaches clamoring for a '3 second call'?:D

Yeah: "not enough Cs 133 periods, coach." :p

My standard response is, "Coach, that wasn't three seconds even in dog years."

BTW - are dog years metric? I hope not. WOOF.
