If you have a hammer, use it everywhere you can, but I do not claim that everything is fractal.

If you look at a shape like a straight line, what's remarkable is that if you look at a straight line from close by, from far away, it is the same; it is a straight line.

A fractal is a mathematical set or concrete object that is irregular or fragmented at all scales...

I had very, very little training in taking an exam to determine a scientist's life in France.

It was a very big gamble. I lost my job in France, I received a job in which was extremely uncertain, how long would IBM be interested in research, but the gamble was taken and very shortly afterwards, I had this extraordinary fortune of stopping at Harvard to do a lecture and learning about the price variation in just the right way.

Being a language, mathematics may be used not only to inform but also, among other things, to seduce.

Engineering is too important to wait for science.
