  • My First PC Weighed 25 Pounds

    February 2, 2014 at 5:33 pm

    My children like to make comparisons between the technology I had growing up and what they have today. In the course of a recent conversation on this topic, it occurred to me that, having been born in 1966, I have lived through the entire evolution of the personal computer and the internet.

  • We Can Afford More Math Textbooks

    January 19, 2014 at 9:05 pm

    As an engineer, I have had a lot of math education in my life, everything from multiplication tables to systems of partial differential equations.  I was quite successful in these classes due in part to the good fortune of innate ability, but also, I firmly believe, because for every class I had a textbook of […]

  • Smog, The Desolation of Shanghai

    December 15, 2013 at 9:54 pm

    The news last week contained many pictures like the one above of a monumental smog enveloping the city of Shanghai, China.
