Growing up in Oak Ridge TN in the ‘60s, terms like “homogeneous reactor,” “molten salt reactor” and “breeder reactor” were frequently used, although I couldn’t have explained them at the time. Research into nuclear power became the mission of Oak Ridge National Labs after the war under the direction of Alvin Weinberg. A few years […]

Most of the earth’s oxygen doesn’t come from forests or jungles but from ocean plankton. A recent survey found an alarming drop in Atlantic plankton levels likely due to increased atmospheric carbon dioxide and resulting ocean acidification. “Plankton is a blanket term for the billions of tiny sea organisms living close to the surface of […]

I’m not a big consumer of liturgical music. I still listen to Handel’s Messiah on Christmas. So it surprised me when I found myself enjoying a boxed set of LPs of Bach’s St. Matthew Passion recorded about 50 years ago. It’s in German, of course, so I’m not following the libretto, just the voices and […]

I grew up in Oak Ridge TN, where the uranium was enriched for the Hiroshima bomb. There’s a recent piece on the NYT on Oak Ridge and desegregation. One of the local players at the time was Waldo Cohn, a chemist and symphony conductor, who was on the school board at the time. Here’s his […]

Ammosexual amateurs think a gun gives them superpowers. In reality, trained law enforcement only hit their target ca. 30% of the time on average at close range in an active shooter event. And that’s with training and regular practice. Unless you’re training regularly, you’re not going to protect yourself with a gun, and you’re likely […]

It appears that, vaccines nonwithstanding, COVID-19 will be endemic for a long time. Enforcing masking and social distancing/lockdowns are not sustainable in American society. We need engineering fixes that don’t depend on each person’s sense of civic responsibility. Kevin Drum points to two engineering fixes that would dramatically reduce infection rates: better ventilation and installation […]

“Few crimes are more harshly forbidden in the Old Testament than sacrifice to the god Moloch (for which see Leviticus 18.21, 20.1-5). The sacrifice referred to was of living children consumed in the fires of offering to Moloch. Ever since then, worship of Moloch has been the sign of a deeply degraded culture. Ancient Romans […]

“Until we are done with the ironies of history (because they will never be done with us), the image of Trotsky will not dissipate.”~Christopher Hitchens I’ve had a lifelong fascination with socialism, communism and the Cold War. This probably springs from having grown up during the Cold War at nuclear ground zero for World War […]

I started teaching medical students in 1988 and have been an instructor and course director for one or more first-year med school courses continuously since 1990. When I started, there were two full years of pre-clinical course-work. Now we’re down to a year and two-thirds and there are plans to shrink further. Some medical schools […]

I just finished Robert Service’s biography of Lenin. The “Marxism” of Lenin was not Marxist at all. Classical Marxism holds that capitalism must achieve a high level of industrialization before the workers can overturn the landlords and factory owners and collectivize the fruits of labor for the benefit of workers. Like Mao, Lenin retrofitted socialist […]
