The exact details will have to remain a secret, but I can tell you
that it involves fibonacci sequences, monte carlo methods,
differential equations, recursion, neural networks, priority queues,
referential transparency, lambda calculus, bipartite graphs, the phase
of the moon and the tire pressure of John Cleese's bicycle.
Nancy, I can understand the other factors, but what do neural networks
have to do with it?
ha ha ha a noob would ask that question. You need to draw the
attention of educators.
I know what it is to draw the attention of educators, and be selected
for I.Q. testing and advanced placement. I don't have a degree in
physics, so maybe if I did then this "genius" thing which I've been
assigned might be put to better use on this subject.
I have a gift for looking past the obvious and discussing the
abstract. I saved a lot of people of many different ethnicities. You
did know that in Junior high school I memorized the Latin genus of
all the snakes in North America? I was a herpetologist by age 15. I
am a master chess player.
You can call yourself a creative genius when you've done what I've
done. My walls are covered with the first run editions of /intricate
valuable artwork. I have the originals safely stored away too. All
these pieces were commissioned before they were started, and they
represent thousands of dollars in revenue. They were all done by the
same artist.

Yes and I've used it. In my opinion it isn't very good due to the messy
way Excel deals with complex numbers, but useful if you haven't got any
better software available.
Google didn't have any quick obvious hits.
Have you tried the Excel help?
Excel would be a cheap easy way demonstrate FFTs in the classroom.
There are plenty of free calculators on the web, for example:

Keep them coming, I may eventually understand this subject ....

A Fourier transform is a mathematical technique to transform from time
domain (what you would see on an oscilloscope) to the frequency domain
(what you would see on a spectrum analyzer).
An FFT (Fast Fourier Transform) is a very efficient algorithm for doing
a Fourier transform on sampled data.

Has anyone ever heard about Fourier transforms on Excel? Google

Excel would be a cheap easy way demonstrate FFTs in the classroom.
The first column would be phase angle and 2nd column would calculate
A1sin(w1*t + phi1) + A2sin(w2*t + phi2) etc. for a time domain
signal.
Go down 256 cells and start something like the divide and conquer
approach.
A1, A2, A3 . . . An and phi1, phi2, phi3, . . . phin would output
in two column of cells dedicated to various frequency ranges.

How do you expect to tell the difference?I don't want to see a sin or cosine curve if the original curve was a
polynomial.
Normalized versions of the original and the final can appear togetherI don't want to see a sin or cosine curve if the original curve was a
polynomial.
