Several of my students still express anxiety about “over”population as part of urbanization. This anxiety is shaped by Paul Ehrlich’s 1968 book, The population bomb. The book has been highly influential ever since it was published more than 40 years ago. This is unfortunate, because it contains a glaring conceptual flaw that demographers have known […]

Since I teach at a large state university, I have several veterans in my classes every semester. This is incredibly valuable for the way I teach, because veterans have direct experience of federal policies, experience of different cities and countries, and a nuanced perspective on geopolitics. So I am thankful for their presence, in addition

I immediately set to building the galley-hatch. I continue to learn how to apply greater pressure for field-bending sheets of plywood. Here I

I have been cranking away on the trailer as fast as I can, so I am inserting this blog post after-the fact. This page describes the fabrication of the components. Here is the left sidewall, under construction in our living-room. A few things visible in this image: 1) On my dad’s advice I sanded the

[Written on the day that the Supreme Court overturned DOMA and dismissed the Prop 8 appeal, enabling the expansion of marriage-rights in California.] Today I can wear my wedding-ring with pride. Today our wedding-vows are affirmed. Today, Love triumphed. The black-robed ministers of justice acknowledged the higher power of Love and the recognition of commitment,
