In a December 2015 article in Forbes, William Pentland seeks to answer the question “What is so revolutionary about Germany’s Energiewende?” Mr Pentland begins: Germany’s energy revolution has become the perennial punching bag of American energy policy. In particular, American … Continue reading
(Clarifying language added 4 Apr 2016, 12:26 EDT.) I just watched an episode from the last season of Star Trek: The Next Generation entitled “Force of Nature.” As anyone who pays the least attention to this blog knows, opposing human … Continue reading
Or is Governor Baker and the Massachusetts House going to subcontract that to other states, like Maine, Rhode Island, Vermont, and New York? They are coming. Update, 2016-02-23 Where does Massachusetts get its energy now?

If attempting to simulate from a multivariate standard normal distribution in a large dimension, when starting from the mode of the target, i.e., its mean γ, leaving the mode γis extremely unlikely, given the huge drop between the value of the density at the mode γ and at likely realisations Continue reading
I have just created the Massachusetts Solar Suburbs Google group. It’s Welcome Message reads: Welcome to the Massachusetts Solar Suburbs! This group exists to provide a forum for owners of solar installations, typically residential, or serving residences, to share their … Continue reading

Cauchy Distribution: Evil or Angel?. From Professor Christian Robert.
Professor Christian Robert tries to help out a student of MCMC on Cross Validated and earns the comment that his help had “the most patronizing start to an answer I have ever received“. I learned a new term: primitivus petitor.
