In an experiment on the Moon, Apollo 15 Commander David Scott, dropped a geological hammer and a falcon feather simultaneously*. I can’t imagine Galileo ever considered that his thought experiment would be realized, or maybe that’s what he was thinking about in the fall of 1609 when was looking at the moon through his telescope and created, in watercolor, the first realistic depictions of the moon in human history*.

Episode 134 of the podcast features recordings from the moon (Apollo/NASA), recordings from earth (boat ride, coffee shop, and driving on a highway), sounds made on my computer (a Roland TR-606 drum machine emulation, and a computer assisted composition: flute, clarinet, and piano).
