This show is full of science news from “hidden hearing loss,” to tracking the intensity of the Earth’s magnetic field using ancient pottery, to cognitive dissonance and How to convince someone when facts fail. Plus science events in the area including a These Vibes Are Too Cosmic live show at Taplin Auditorium at Princeton University on Friday, February 24th. It’ll be all about the Science of Memory.
In the primary segment of the show, Stevie spoke with Princeton graduate researcher in classics and host of the podcast Ancient Greece Declassified, Lantern Jack (pseudonym), came on the show to discuss ancient cosmologies. Lantern Jack began with ancient Greece, where the geocentric model reigned and where we have the best, early models of the universe (that we know of).
We discussed geocentric and heliocentric models, how the first calculations of the size and distance to the Moon and the Sun were made, and mused about whether there were or weren’t lenses available.
Then, towards the end of the show Lantern Jack told us a bit about the Antikythera mechanism – believed to be an early analogue computer and actually physical cosmological model, recovered from a shipwreck in 1901.
