Eric’s Enlightenment for Tuesday, April 21, 2015

  1. The standard Gibbs free energy of the conversion of water from a liquid to a gas is positive.  Why does it still evaporate at room temperature?  Very good answer on Chemistry Stack Exchange.
  2. The Difference Between Clustered, Longitudinal, and Repeated Measures Data.  Good blog post by Karen Grace-Martin.
  3. 25 easy and inexpensive ways to clean household appliances using simple (and non-toxic) household products.
  4. A nice person named Alex kindly transcribed the notes for all of Andrew Ng’s video lectures in his course on machine learning at Coursera.
