In high school I had my head among stars, galaxies and nebulae, I wanted to be an astronomer and I had a math and physics teacher who made me dream. Perhaps he was responsible if I became passionate about science until I got a degree in this field and it was thanks to him that I was able to develop the skills to succeed. When I enrolled in that institute and I happened to be in that class, someone was warning me about serious trouble from that professor, a madman, out of his mind, a real nutcase. Others considered him a genius, with a teaching method of his own, very difficult to follow. I mean, the advice was to change class.
