Hi Gerasimov;

Welcome to the forum.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Hi :)

What type of math do you like? What type are you good at? What is the age and type of the audience?

Re: Hi :)

Then you can do it about the Fibonacci Sequence. There is probably more literature on that sequence than all the rest put together. There is even a journal devoted to it.

Re: Hi :)

They call it The Fibonacci Quarterly.

I did some work with L systems when I was a beta tester for Mupad.

Re: Hi :)

Hmmm, is it wise to mention some topic that you know less than even I do? You could always leave it out...

Re: Hi :)

I can give you some nice visual images for an L system but I am not an expert on them. They might make a nice display.

Re: Hi :)

A logarithmic spiral is best described right here.

Re: Hi :)

Yes very much so.

There is an online site that will generate L systems. It is better than mathematica for this job.

Re: Hi :)

It is called the Fibonacci Quarterly. A university library would have it in the reference section.
