I am back from my last travels within the fair island of Ireland. A lot of impressions, ideas, and topics to blog about. Unfortunately, experience shows that while I travel I simply don’t have the leisure to post. As a result, this blog has been sadly neglected. Now that I am back hom

I’ve just returned from California, where I spent last two weeks. I dislike long-distance air travel, and when I do it, I try to hit as many birds with the same stone, so to speak. This means bunching up as many talks and visits as possible. On this trip I started at Stanford, then we

In this last installment on thoughts provoked by Sci Foo sessions, I’d like to speculate about what might happen if we (God forbid) encounter an extraterrestrial civilization in any not-too-distant future. As usual, I look at this question through the lens of social and cultural evolu

In the previous post I argued that although it looks like the period between 1 and 1500 AD was one of stagnation, and even regress (European ‘Dark Ages’, etc.), under the surface there was a lot of technological and social progress. In China, again, agricultural techniques continued t

My previous blog discussed the startling idea that war, despite all the blood, death, and suffering it has inflicted on countless humans over the ages, is actually good for something. As the historian and archaeologist Ian Morris argues, war “drove the creation of increasingly effecti
