Supramolecular chemistry is the chemistry of the intermolecular bond, covering the structures and functions of the entities formed by association of two or more chemical species.
When I started doing chemistry, I did it the way I fished - for the excitement, the discovery, the adventure, for going after the most elusive catch imaginable in uncharted seas.
Whether that coherence obtains universally is a question that need not be answered here since only those parts where the coherence has actually been found become part of Science.

Although reading the classics in Latin in school may be not as fulfilling as it would be at a more mature age, few scientists can afford the time for such diversion later in life.
We may say that life has borrowed from inanimate processes the same basic mechanism used in producing those striking structures that are crystals, with their beautiful plane faces.
I live in my house as I live inside my skin: I know more beautiful, more ample, more sturdy and more picturesque skins: but it would seem to me unnatural to exchange them for mine.
And as we continue to improve our understanding of the basic science on which applications increasingly depend, material benefits of this and other kinds are secured for the future.
I had changed from being a mathematician to a practicing scientist. I was increasingly embarassed that I could no longer follow some of the more modern branches of pure mathematics.
A few atoms added here, subtracted there, is all it takes to make the difference between male and female sex characteristics, between a harmless molecule and a deadly addictive one.
I am a teacher, and I am proud of it. At Cornell University I have taught primarily undergraduates, and indeed almost every year since 1966 have taught first-year general chemistry.

A new sense of shared international responsibility is unmistakable in the voices of the United Nations and its agencies, and in the civil society of thousands of supra-national NGOs.
Life with a scientist who is often changing jobs and is frequently away at meetings and on lecture tours is not easy. Without a secure home base, I could not have made much progress.
In arranging the bodies in order of their electrical nature, there is formed an electro-chemical system which, in my opinion, is more fit than any other to give an idea of chemistry.
The war project at Stanford was essentially completed, and I accepted an offer of an Assistant Professorship at the University of Minnesota, which had a good biochemistry department.
