We all knew him as Mr Wizard, of course. He was a great no-nonsense science teacher who influenced a whole generation of kids — he taught us that science was a very down-to-earth process that worked. He didn’t have a lot of flash and pizazz, and the production values on his show were downright cheap, and he never seemed to get carried away; he was the exact opposite of the televangelists, who were all gaudy extravagance and no results.
True nerds loved Mr Wizard. Being undemonstrative nerds meant we never said it. We’ll miss you, Mr Wizard.
