We talk about how rice is grown, how eyes are colored, how time is told, and, of course, a scheme.

We consider too much rain, too many dinosaurs, too much bad stuff happening, and too many MIDI notes.

A new border appears, and an old new fish appears; we measure stars, and measure aging. Bonus: a special frog fact.

Vespasian pays for a colosseum, the bible describes angels, frogs jump into the air, and cities tell us how to compost.

Allen reveals why pills are the way they are, Arik reveals why trucks are the way they are, and we catch up on followup.

Turtles breathe in a very peculiar way, nut butter makes a mess, bacteria get crushed, and Arik goes on a quest for carbonation.

Allen attempts to throw things into a volcano, Arik attempts to clean his dishes, and hippos attempt to get around.

We have a bridge to sell you, as do renaissance philosophers, before we discuss some life forms that earth has an unreasonable number of. In the post show, Allen finally gets an EV.

Allen lays out a wine scheme, Christa Mrgan explains the wonders of temporal resolution, Allen checks in on creatures’ dangerousness, and we learn a couple things about George Orwell.

Allen shares some puzzling genetics, Arik shares some puzzling puzzles, we go back to the ’90s, and forward to the ’30s.
