I’m in a celebratory mood. Microcosm is published today. In my mind, I can see the books moving out of warehouses onto trucks, off to book stores and front door steps. This morning I read a great review from Mykola Bilokonsky at Newsvine. (“What are you waiting for?” he asks.) And tonight I’ll be having a little get-together, with the weather cooperating in splendid fashion. To spread the cheer, let me invite you to participate in a contest to win a copy of Microcosm that I will personally sign.

In tomorrow’s New York Times, I take a look at the evolution of intelligence. Or rather, I look at its flip side. Scientists and the rest of us are obsessed with intelligence–not just the intelligence of our own species, but any glimmer of intelligence in other animals. I’ve written plenty of stories myself on this research, from the social brilliance of hyenas to the foresight of birds. But if these faculties are so great, then why aren’t more animals smart? The answer, experiments suggest, is that learning and memory have nasty side-effects. They can even shorten your life (at least if you’re a fly).

Drew, an oceanography graduate student, writes:

“This, on my leg, is the incompressible form of the conservation of mass equation in a fluid, also known as the continuity equation. When people ask what it means, I say it defines flow. Sometimes I say it means you should have studied more physics, but that is only when I am feeling like being funny. What it means in more detail is that, for an incompressible fluid, the partial derivative of the velocity of the fluid in the three spatial dimensions must sum to zero. It therefore concisely states the fundamental nature of a fluid.
