Featured Program

Full-Spectrum Science with Ron Hipschman: Radioactivity

8:00 p.m.
Kanbar Forum

Join Exploratorium scientist Ron Hipschman for colorful explorations of the physical world.

What's going on inside the nucleus of an atom? Why does it spit out radiation? Did you know that you are exposed to radioactivity every day? Learn the facts about this somewhat controversial topic.

Since joining the Exploratorium in 1971, Ron Hipschman has worked as an exhibit developer, author, teacher, and webcast host. He currently works on the Exploratorium’s Environmental Initiative, implementing and maintaining a collection of environmental monitoring sensors and developing visualizations for the Fisher Bay Observatory Gallery’s super-resolution media wall. In addition to Full-Spectrum Science, Ron hosts the monthly After Dark series Everything Matters: Tales from the Periodic Table.
