Orla writes, “I’m a Zoology undergrad in Dublin, Ireland. I got this tattoo of an orangutan to ensure that, even if they die out in the wild, which seems to be quite likely, they’ll still be remembered. The noblest of the apes sits on my lap forever.”

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.

“Why are humans so smart?” is a question that fascinates scientists. Tadeusz Kawecki, an evolutionary biologist at the University of Fribourg, likes to turn around the question.
“If it’s so great to be smart,” Dr. Kawecki asks, “why have most animals remained dumb?”
Dr. Kawecki and like-minded scientists are trying to figure out why animals learn and why some have evolved to be better at learning than others. One reason for the difference, their research finds, is that being smart can be bad for an animal’s health.

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.
