Planck, 1931, on the introduction of quantized oscillators
"I can characterize the whole procedure as an act of despair, since, by
nature I am peaceable and opposed to doubtful adventures."
Rutherford, 1913, on the discovery of the nucleus
"It was quite the most incredible event that ever happened to me in my
life. It was as incredible as if you fired a 15-inch shell at a piece of
tissue paper and it came back and hit you."
