Blowing off some steam.

- 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.
