Cheap Astronomy - Fantastic Physics Formulas, Episode 10

Blowing off some steam. Read by Barry Haworth and Duranee, written by Steve Nerlich, with technical advice from Stephen D'Souza.   - The orbit equation: There are several orbit equations around, but this orbit equation tells you what orbital velocity you need to maintain an orbit at a particular altitude.   - Entropy and the Inequality of Clausius: Getting to this formula requires a bit of a story, but it’s worth it as it ends up explaining which direction the Universe is moving in. The conversion of heat, a form of energy, into work dates back to ancient Roman times, although heat engines built to do proper industrial work first appeared around the start of the 17th century, mostly steam engines that first pumped water out coal mines and then later drove locomotives, as well as driving a range of other piston-driven machines.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
