How do a Fast Fourier Transform by Cooley and Tukey Algorithms ? Why High Potential with a high level QI don’t understand official physics memorization ? The answer is in the question : nobody ask you to … understand ! Then let’s read the original engineers experts ! Come Back to … 1964.

It is a simple demonstration in thesis annexis. Here is a resume. (Not so clear to read for you. We know it)

## Cooley and Tukey Number of Calculations Evaluation

If we perform a Fourier Transform from the original document [COOLEY-TUKEY-1964] we take all $N$ decomposition terms $A(k)$ then we multiply each $k$ order term by exponential $exp(2.i.\pi.\frac{k.j}{N})$. We get a « frequential » $X(j)$ term.

We changed notation to $X(k)$ time and $F(n)$ frequency signals to match with engineer’s needs and … then we change also sign and recalibrate to $\frac{1}{\pi.N}exp(-2.i.\pi.\frac{k.n}{N})$ for energy conservation !!!

That’s all folks ?

Done !

2016 has been productive : After a Master in Sciences in 2012 I was a sciences professor for two years and in 2016 I got a second Master in Teaching and Pedagogy. I leaved French Institution to work by my own on « understanding physics methods for scientists« . I have got a lot of discovers.

Now I work hard for a lonely PhD in Physics without help. In french I use to say « Un Doctorat en Lousdé » or in English « Very Effective Hidden Doctorate » and I am proud of it. Now I am a very high level, clever, fool scientist by my own brain, hands and skills. I achieved all by myself.

I had written some articles in this web site extracted from my annex thesis works and measurements. I know it is difficult for you to understand what I wrote because I don’t explain all my works. I get some demonstrations, proves, algorithms, explanations, understanding and logical links and meanings on somes program documents. I can’t write all in this web site. I display the tip of the iceberg. It is a huge work under sea !!!

However, the basic science problem is something quite different. I keep this in my mind. It’s to difficult to explain but there are some logical links with all those articles. Do we try to understand what they are ? I wish you « bon courage ». Maybe you can discover, like me, some lights to go further …
