“I believe that one of the greatest mistakes made by human beings is to want certainties when trying to understand something.The search for knowledge is not nourished by certainty: it is nourished by a radical absence of certainty.Thanks to the acute awareness of our ignorance, we are open to doubt and can continue to learn and to learn better. This has always been the strength of scientific thinking—thinking born of curiosity, revolt, change.”

Carlo Rovelli
