At best a large molecule. That’s how insanely information dense the quantum wavefunction really is. And yet we routinely simulate systems with thousands, even millions of particles. How? By cheating. Using the ultimate compression algorithm: Density Functional Theory (DFT). Let’s learn how to cheat the universe.Check out the Space Time Merch Storehttps://www.pbsspacetime.com/shopSign up for the mailing list to get episode notifications and hear special announcements!https://mailchi.mp/1a6eb8f2717d/spacetimeHosted by Matt O'DowdWritten by Graeme Gossel and Matt O'Dowd Post Production by Leonardo Scholzer, Yago Ballarini, Pedro Osinski, Adriano Leal and Stephanie FariaGFX Visualizations: Ajay ManuelDirected by Andrew KornhaberAssistant Producer: Setare GholipourExecutive Producers: Eric Brown and Andrew KornhaberExecutives in Charge (PBS): Adam Dylewski, Maribel Lopez Director of Programming (PBS): Gabrielle Ewing Spacetime is produced by Kornhaber Brown for PBS Digital Studios.This program is produced by Kornhaber Brown, which is solely responsible for its content.© 2021 PBS.
