  • Cold Fusion Part II: History 1869 to 2015

    September 20, 2015 at 3:15 pm

    Last week in Part I of this three column series, I discussed the science of cold fusion. I had been considering writing about cold fusion for some time. Then last month the U.S. patent office issued a patent for a fluid heater to Italian inventor Andrea Rossi that, as we will discuss further below, purports […]

  • Cold Fusion Part I: The Science

    September 13, 2015 at 11:00 am

    Last month Italian inventor Andrea Rossi was granted a U.S. patent for a fluid heater. At first glance, that’s not a particularly gripping opening sentence for a lively or interesting science column. But there is more to the story, a lot more. First off, the heat source in Rossi’s invention is purported to cold fusion. […]

  • Oxygen Free Atmosphere versus Holding Your Breath

    September 6, 2015 at 9:28 am

    Twice a year I head to my home town of State College, Pennsylvania to give a presentation to freshmen Chemical Engineering students at Penn State University entitled, “What a Chemical Engineer Actually Does.” It’s a fun trip for me. I listen to an audio book on the drive, visit with my parents while my mom […]

(Here are links to those columns, Part I, Part II, and Part III.) I also described my own […]

  • The Science of Hail

    August 2, 2015 at 9:51 pm

    It’s summer here in the Southern Part of Heaven and that means it’s time for hail storms. So I thought a column on the science of hail would be timely. Plus, my wife recently asked me a question about hail and my explanation was a bit disorganized, so I hope this one is an improvement. […]
