Usually if you walk into the Brattle with an introductory math textbook you’ll receive a polite ‘no thank you.’ However, it’s a slightly different story when that textbook was published in 1695. In today’s episode, we’re looking at a still-pretty-accurate antique trigonometry book, written in Italian and complete with engraved illustrations and folding diagrams. We’ll talk about what makes technical volumes valuable—aside from sheer age—and why Brattle is less math-phobic than most secondhand book shops (an academia-rich location, strong employees, and Ken’s background in chemistry play a part). Learn how it all adds up on today’s tangential #brattlecast.
Brattlecast #144 - The Astronaut Book
Today we’re looking at a fresh arrival to the shop: a copy of The Astronauts: the Story of Project Mercury, America's Man-in-Space Program, by Martin Caiden. On its own, it’s an interesting account of the early space race, but a handful of illustrious signatures really cause this particular volume's value to skyrocket. We’ll explore this and other space-adjacent collectables—including science fiction and photographs from the lunar capsules—on this far-out #brattlecast.
