Recently added articles: Stellar parameters, rowing boats, water propelled rockets.

Recently added material in ScienceBits includes:
  • Estimate the basic stellar parameters using the tendency for energy equipartition. In particular, the temperature at the center of the sun, the mass-radius relationship of white dwarfs and their Chandrasekhar limit are all estimated. These were taken from my order-of-magnitude course notes.
  • Row Row Row your boat, but at which maximum speed? This is a classic example of an order of magnitude analysis giving a lot of physical insight (and impressive predictive power).
  • Analysis of the classic homemade water rocket, taken straight out of my first year physics majors classical mechanics notes. There is even a rocket simulator with which the trajectory can be calculated and graphed.
