Come be in your elements with Exploratorium host and scientific raconteur Ron Hipschman—follow tales of intrigue and invention, join in dynamic demonstrations, and uncover fascinating connections between individual elements and our collective human experience.
In this new Everything Matters segment, get to know the colorful element cadmium. Once used in rechargeable batteries, TV picture tubes, and artists' pigments (its use has been curtailed due to its toxic nature, though you can still find Cadmium Red and Yellow paint if you look), its light once served as the standard for measuring certain lengths. Today, you'll find it in photocells, quantum dots for LCD televisions, control rods in nuclear reactors, and solar cells.
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 Bay Observatory Gallery’s super-resolution media wall. In addition to Everything Matters, Ron hosts the physics lecture series Full-Spectrum Science.
