On this episode, we talk about great big events, the interconnectedness of everything, and why it's so difficult for us to perceive outsized happenings — or in some cases even believe they exist.

We also take a look at cyanobacteria, riff on Mount Tambora, and learn the amazing name of a proto-bicycle.

Let's Know Things is produced and hosted by Colin Wright.
