Nature by numbers

11 July , 2010

Teaching mathematics in mathematics education, I now and then have lectures on the mathematics found in nature. I rather like this subject and enjoy finding new ways of attacking the problems in there. I must say, that I don’t think I have seen a nicer illustrations of the phenomena og Fibonacci numbers and golden sections, than can be found in the video below. It has been circulated from YouTube for some time and I hope you will enjoy it too.

My guess is, it serves nicely as a kind of repetition of the concepts for students already familiar with them.
