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?

A Day at the Beach
A short while later they decide to come back. I watch them, seeing them from a distance as I don't when they are close by. DD2's legs are almost as long as her sister's despite their two-and-a-half years age difference. And DD1's legs are almost as long as mine! Her figure is starting to develop and I am shocked to notice once again just how lovely she is. They are growing up so fast. Suddenly a wave a panic washes over my heart and grabs me by the throat. I realize in only a few years, I will not be able to watch them when they come to the shore or go out with friends. Then there will be boys and smoking and drugs and... No. I stop myself. I can't worry about those things now.
As they come towards me I pick up their towels to hand to them to dry off. But no, they don't want the towels. The both throw themselves down on the warm sand and roll around in it like puppies until they are covered. They proceed to play "sand monster" and take turns burying each other in mounds of sand, then rising up and chasing around. I admonish them that they will not only have to rinse off before they get back in the car, but that they will have to rinse off outside at home before they can come in and bathe!
And then I sigh with relief and think to myself "There's still time."
