Quotations for Today | |
| The progress of science has always been the result of a close interplay between our concepts of the universe and our observations on nature. The former can only evolve out of the latter and yet the latter is also conditioned greatly by the former. Thus in our exploration of nature, the interplay between our concepts and our observations may sometimes lead to totally unexpected aspects among already familiar phenomena. |
| Heredity is to-day the central problem of biology. This problem may be approached from many sides�that of the breeder, the experimenter, the statistician, the physiologist, the embryologist, the cytologist�but the mechanism of heredity can be studied best by the investigation of the germ cells and their development. |
| But as no two (theoreticians) agree on this (skin friction) or any other subject, some not agreeing today with what they wrote a year ago, I think we might put down all their results, add them together, and then divide by the number of mathematicians, and thus find the average coefficient of error. (1908) |
