Originating my my childhood reading (and I read a lot then), I have a number of heros. One was and is Galileo Galilei. It was refreshing to read about him again in The Economist. He used the power of his telescope and his mind to recognize that the “accepted” science–the science that was not under debate, had “been decided”, and was no longer is an issue of “debate”–was wrong. He changed the world, and paid a price for his understanding of that world.
Something we should remember in the 21st century.
