About this episode

This episode explores the foundational role of silicon in human civilization beyond its association with Silicon Valley.

Like a typecast actor who can’t escape the blockbuster franchise they’re known for, the element of silicon is inescapably associated with Silicon Valley. But that association undersells just how important, how foundational silicon is for human civilization. It’s another edition of “The Element of Surprise,” our occasional series about the hidden stories behind the periodic table’s most unassuming atoms, isotopes, and molecules. And this time, it’s all about silicon. From humankind’s early tools, to the quartz crystal hidden in your digital watch, we’ll cover how this underrated element has a lot more to offer than one California valley might suggest. Featuring Vince Beiser, Megan Brewster, and Rachel Maines. Produced by Taylor Quimby. For full credits and transcript, visit outsideinradio.org.
