“This new quantum mechanics promised to explain all of chemistry. And though I felt an exuberance at this, I felt a certain threat, too. “Chemistry,” wrote Crookes, “will be established upon an entirely new basis…. We shall be set free from the need for experiment, knowing a priori what the result of each and every experiment must be.” I was not sure I liked the sound of this. Did this mean that chemists of the future (if they existed) would never actually need to handle a chemical; might never see the colors of vanadium salts, never smell a hydrogen selenide, never admire the form of a crystal; might live in a colorless, scentless, mathematical world? This, for me, seemed and awful prospect, for I, at least, needed to smell and touch and feel, to place myself, my senses, in the middle of the perceptual world.”

“I have never had the sort of experience the mystics talk about, never felt a revelation of reality through or beyond nature, never felt like Adam in Paradise, never felt, in direct experience, that the world is wholly other than it seems…The nearest I have come to such experiences are glimpses of my own creative powers…and these are moments or intervals of inspiration rather than vision. I’m not sure that I want it unless I can have clarity about other things with it.”

“We may, I believe, anticipate that the chemist of the future who is interested in the structure of proteins, nucleic acids, polysaccharides, and other complex substances with high molecular weight will come to rely upon a new structural chemistry, involving precise geometrical relationships among the atoms in the molecules and the rigorous application of the new structural principles, and that great progress will be made, through this technique, in the attack, by chemical methods, on the problems of biology and medicine.”

“Because never in my entire childhood did I feel like a child. I felt like a person all along―the same person that I am today.”

“I shall attack Chemistry, like a Shark.”

“I never felt the need to do what everyone else did. And I wasn’t troubled by the fact that other people were doing other things.”

“Me?! What? I don’t know, unless I must go to the dictionary and learn what a crook is. I’ve never been a crook. … I'm saying I'm not a crook, I have never been a crook. I will never be a crook.”

“I had a trumpet, but I didn't want to be a trumpet player. I wanted to be some type of athlete or in some type of scholarly activity, be a chemist or something—I had my little chemistry set, and I like playing with it.”

“The central idea of quantum theory is that energy, like matter, is not continuous but it exists only in discrete packets. Discreteness of matter and charge on the microscopic scale seems entirely reasonable and familiar to us, based on the modern picture of atomic structure. But, the idea that energy also exists only in discrete chunks is contrary to our experience of the macroscopic world. The motions of a soccer ball rolling up and down the sides of a gully involve arbitrary amounts of kinetic and potential energy; nothing in ordinary human experience suggests that the energy of a system should change abruptly by “jumps.” Understanding quantum mechanics requires that we develop a new kind of physical intuition, based on the results of experiments that are impossible to understand using classical mechanics. These results are completely divorced from ordinary human experience in the macroscopic world around us, and our physical intuition from the macroscopic world cannot be transferred to the quantum domain. We must resist the urge to interpret these quantum results in terms of ordinary experience.”

“I never waited for my Irish Cream coffee to be the right temperature, with a storm happening outside and my fireplace crackling… I wrote every day, at home, in the office, whether I felt like it or not, I just did it.”
