What do stars, supernovas, and ancient civilizations have in common? The answer lies in the elements that shape our universe—and our lives. This course explores the cosmic origins and earthly significance of eight iconic elements: hydrogen, helium, carbon, oxygen, silicon, iron, gold, and uranium. Tracing their stories from the Big Bang to modern applications, we will blend insights from astrophysics and chemistry with history, culture, and discovery. Each session will focus on a pair of elements, examining their formation in stars, their chemical uniqueness, and the ways they’ve influenced technology, myth, and society. Inspired by Carl Sagan’s observation that “to make an apple pie from scratch, you must first invent the universe,” this seminar invites students on a sweeping intellectual journey—from the atomic to the astronomical. The path to an apple pie involves enormous amounts of time and space. Course material is based on the instructor’s forthcoming book with MIT Press. Sessions include lecture, discussion, and Q&A, with opportunities to share perspectives and real-world examples. Readings and notes will be provided as PDFs.
