“In research, one is always studying the unknown. The scientist is an explorer.”

“Most chemists have a secret ambition: to be a synthetic chemist.”

“Chemistry has been termed by some the central science.”

“We sought to create 'host' molecules with cavities that could selectively bind 'guest' molecules, much like an enzyme binds a substrate.”

“The intellectual gratification that comes from discovery is one of the great rewards of a scientific life.”

“Originality in science is the discovery of new propositions that are true.”
