Fermi Paradox: Student Art
The physicist Enrico Fermi was prompted to pose the question we now refer to as the Fermi Paradox by this 1950 Alan Dunn New Yorker Magazine cartoon showing space aliens stealing trash cans from New York City. Here is the original drawing upper left alongside some updated versions by 6th Grade Science students from San […]
Occam’s Razor: Student Artwork
This wonderful depiction of the fourteenth century Franciscan Friar William of Ockham choosing a razor was drawn and presented to me by a Sixth Grade science student in San Anselmo California. Occam’s Razor is, of course, a problem-solving principle. It states that, when presented with more than one possible competing answers to a problem, the […]
Maj. Stephen Del Bagno (1984 – 2018)
I was deeply saddened to hear of the passing Maj. Stephen Del Bagno who died yesterday in a training accident with the Thunderbirds Air Demonstration Squadron.

Gen. Barry McCaffrey on Donald Trump
Reluctantly I have concluded that President Trump is a serious threat to US national security. He is refusing to protect vital US interests from active Russian attacks. It is apparent that he is for some unknown reason under the sway of Mr Putin. Retired four-star U.S. […]
