Zitat des Tages von H. Robert Horvitz:
It was my father who - after, at age 15, I had attempted unsuccessfully to drive the family car using a 'borrowed' key and knocked down a wall of the garage - convinced me over the telephone not to run away from home and who then came home from work not to punish me but rather to console and comfort me.
My scientific pursuits have led to many opportunities and responsibilities beyond those of simply doing research. For example, as a beginning graduate student, it never occurred to me that the life of a scientist could involve so much travel, something that I have always loved.
