I arrived from overseas to do my graduate study in the U.S. I was looking forward to going to a country where things were done logically. I was told about English versus American spellings: "colour" was "color"; "centre" was "center," and so on.
I also educated myself about pennies, nickels, dimes, and quarters. Not to mention gallons, quarts, pints, miles, yards, feet, inches, acres, pounds (abbreviated "lbs."), ounces, and fluid ounces.
I came across a non-profit organization: The U.S. Metric Association, which was started in 1916!
I wondered, along with the politicians, why the education system was supposedly messed up in America. Here I had come to a country where things were advanced technologically -- where people were smart and illiteracy was almost nonexistent -- yet when I went to the grocery store, the clerk could not hand out the change. He had to wait for the computer to prompt him the "balance due." (I thought he was not too bright, until I myself got into the American system.)
Maybe it is because of this measuring system that American students are foolish. They are still busy trying to figure out how many ounces make a fluid ounce.
We still have to realize the power of zeroes and make those students Foolish.
