1979, education in Biology and Architecture.
1980, I formulate the question of pattern formation of sunflower seeds as: “How can I produce these spirals without a pencil?". I do not permit drawing a continuous curve, nor the application of numeric values.
1987, Aristid Lindenmayer supports my algorithm which develops phyllotactic patterns.
1994 PhD - for the second time I switch from Biology to Architecture.
1990, 1996, 1998, scientific publication of basic principles.
2015, while introducing the concept of Phyllotactic beauty, I propose to play with Apex, the geometrical phyllotaxis generator, which celebrates it's 25th anniversary.
