Novel technologies and ideas that impinge on human biology and their perceived impact on human values have renewed strains in the relationship between science and society.

Fears of creating new kinds of plagues or of altering human evolution or of irreversibly altering the environment were only some of the concerns that were rampant.

Looking back, I realize that nurturing curiosity and the instinct to seek solutions are perhaps the most important contributions education can make.

Novel technologies and ideas that impinge on human biology and their perceived impact on human values have renewed strains in the relationship between science and society.

With time, many of the facts I learned were forgotten but I never lost the excitement of discovery.

Moreover, the concern of some that moving DNA among species would breach customary breeding barriers and have profound effects on natural evolutionary processes has substantially disappeared as the science revealed that such exchanges occur in nature.

But the prospects of designing chemical plants for industrial scale chemical processes seemed far less interesting than the chemical events that occur in biological systems.
