I would have liked to be involved in the development of "Humanism". I share the belief that it is important to trascend in life by trying to improve intellectually and phisically every day. I also believe that education is the most powerful a society has in order to develop itself.
I would also have enjoyed to be involved in the development of "Heliocentrism". The model in which the Sun is the center of the system and all of the planets revolve around it. Altough they were tough times for Copernico, who proposed it, it was a crucial moment in history in which man realized it was not the center of the universe.
