Johannes Kühl, physicist and leader of the Science Section at the Goetheanum, was born in 1953 in Hamburg, Germany. He studied physics in Hamburg and Göttingen, finishing with research in fluid dynamics at the Max Plank Institute. After a year of research at the Science Section at the Goetheanum, he taught physics, chemistry and mathematics at the original Waldorf School in Stuttgart Uhlandshöhe. Since 1996, he has been the leader of the Science Section at the Goetheanum and a member of the collegium for the School of Spiritual Science. Since high school, core areas of interest for him have been modern physics and optics, as well as Goethean science. He has given numerous lectures and seminars on these themes and finally put some of his thoughts into his book, Rainbows, Halos, Dawn and Dusk.
