Radicalism in science is essential to move forward. In the span of two years, four scientific revolutions proved that to be true.

Those four revolutions were in space, nuclear energy, genomics and computing.

“Scientific discoveries come from people thinking thoughts that have never been thought before or people using experimental tools that have not been used before,” said theoretical physicist Freeman Dyson at Wednesday’s morning lecture in the Amphitheater.

Dyson, professor emeritus at the Institute of Advanced Study, shared his experience living through the four radical revolutions that occurred from 1944 to 1945 as the third speaker of Week Eight, themed “Radicalism.”
