Pictures were completely eliminated from mathematics; in particular when I was young this happened in a very strong fashion.

A formula can be very simple, and create a universe of bottomless complexity.

My life has been extremely complicated. Not by choice at the beginning at all, but later on, I had become used to complication and went on accepting things that other people would have found too difficult to accept.

Think of color, pitch, loudness, heaviness, and hotness. Each is the topic of a branch of physics

Humanity has known for a long time what fractals are. It is a very strange situation in which an idea which each time I look at all documents have deeper and deeper roots, never (how to say it), jelled.

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

I conceived and developed a new geometry of nature and implemented its use in a number of diverse fields. It describes many of the irregular and fragmented patterns around us, and leads to full-fledged theories, by identifying a family of shapes I call fractals.
