Fourier Analysis is a mathematical tool which can do a number of things: separate out signals from noise; help identify patterns or trends in data; filter out all unwanted data and focus on a single signal; use approximations to make generalizations; make approximations of real world signals (think electronic music); combine harmonics to get a stronger signal. That's what I'll be trying to do here!! Won't you join me with your comments?

Drivin' 'Cross Texas
Unfortunately for my Dad, Texas is not Germany, and there are speed limits. So on a long stretch of road, where there are few cars and a fairly barren landscape, it is really easy to lose track of how fast you are going. Which he did. And of course there was a state trooper with nothing to do who happened to be parked under one of the few shade trees that were alongside the road. Dad did not see him in time, and knew that he had been caught speeding.
Sure enough, the trooper came up behind us and flashed his lights. Dad stopped and got out of the car to give the trooper his license (this was before the days before law enforcement was afraid of people getting out of their cars). He also needed the registration, and I got it out of the glove box and went to give it to him.
Now as we were traveling in Texas during a pretty warm late spring day, I was wearing shorts and a tank top. I had not received the nickname "Legs" in college without reason! The trooper asked me if it was my car and I said yes. He asked about the engine size and I gave him the specs. He joked with my Dad about how easy it was to speed in a car like that! I got back in the driver's seat while my Dad was still talking to the trooper.
The way my Dad tells it,"That trooper admired her. He admired the car. He was smilin' ear to ear. Musta made his day. And he still gave me a ticket!"
At least he did knock off some miles from his actual speed so the ticket was not so expensive.
