Episode notes
Rocket Science Origins
- Rockets weren't understood until the late 19th and early 20th centuries.
- Konstantin Tsiolkovsky, credited as the first rocket scientist, realized rockets operate on Newton's third law.
Boat Analogy
- Tsiolkovsky explained rocket propulsion with a thought experiment.
- Imagine throwing rocks from a boat; the boat moves opposite to the direction of the rocks—same principle as a rocket.
Rocket Equation
- The Tsiolkovsky rocket equation describes the change in rocket speed.
- It relates exhaust velocity and the ratio of a rocket's final to initial mass.
