It was sad to hear about the passing of Mr. Wizard, Don Herbert, who was such a fixture in my post-Sputnik, race-to-the-moon, informal-learning-of-science life. TV was monitored in our house, but Mr. Wizard was a permissible Saturday program.
He sure knew how to make science a child-centered and relevant fun thing...even thru the grainy black & while venue called early TV. And he grew to meet the times.
Thanks Mr. Wizard!
