Join Exploratorium scientist Ron Hipschman for colorful explorations of the physical world.
You know what time is because of your daily experience, but what seems constant and unchanging is not. In 1905, Albert Einstein threw a monkey wrench in our perception of time and space. Join us as we examine a few of these quirks on a conceptual non-mathematical level. Yes, you can age slower than your twin!
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.
