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?

The Blues - Colored Grey...
Usually this is a good thing when the weather is warm and sunny, or when spring brings its first gentle breezes as opposed to the bitter cold winds of fall an winter.
Today we are having one of our first real dreary fall days. The sky is grey. It isn't really raining hard, but it is just drizzling down so that everything is wet and the air is damp. And it's the kind of cold that catches you off guard, where your jacket is too thin, and you should have worn a scarf. It's just plain miserable weather.
And so are my spirits - grey, damp, gloomy, cold, miserable.
And the change in the weather has also accompanied a fibromyalgia flare. It isn't as bad as they can get, but I just feel yucky, like I'm coming down with the flu. But I know it's fibro rearing its ugly head because of the specific joint pains that I get. And I am so tired I can barely drag myself out of bed.
So I am lurking. Which suits how I feel. Ghostly, barely present, but not completely out of the picture. I enjoy reading all my blog-friends and love hearing from you, but right now I am feeling sorry for myself so I'm just hunkering down for a bit.
I will be back soon, and am trying to write about better times. Jenn-in-Holland is nagging me (again!) about blogging about my birthday. I will get even, however, by making her put in her 2-cents as well. And there are even pictures, which will make it an even more special blog (for me!).
So don't worry. And please don't forget me. I'm still here, but I'm probably in bed right now...
