ex machina

funny. yesterday on conflux i posted a series that explored, in part, explanation versus description in science. today i stumble upon a "new, universal definition of life" founded in the desire to separate descriptive from explanatory definitions:

"Bernard Korzeniewski of the Institute of Molecular Biology at Jagiellonian University in Kraków, Poland, says that definitions of life usually list the attributes an organism must have, such as genes, a certain level of complexity, the ability to reproduce and evolve, and so on. But this, he says, merely describes life rather than providing a useful way of deciding what's alive and what's not.

So Korzeniewski set out to formulate a fundamental definition of life, "which would apply not only to life presently existing on our planet but also to the first living organisms on Earth, as well as to life-like phenomena existing presumably on other planets in the Universe", as he puts it.

His definition is this: "A network of inferior negative feedbacks subordinated to a superior positive feedback." In other words, it's a system that tries to regulate itself to preserve its identity."

cool idea, but i'm not sure about a theory that states that ants aren't alive.

“"it is hard to be brave," said piglet, sniffing slightly, "when you're only a Very Small Animal." rabbit, who had begun to write very busily, looked up and said: "it is because you are a very small animal that you will be Useful in the adventure before us."”

[ about ]

this site chronicles the continuing adventures of my son, odin, who was unexpectedly born on the fourth of july at 25 weeks gestation, weighing 1 pound 7 ounces.

he's quite a fighter and you can always send him a postcard to the most current address listed here if you're inspired by his adventures. see the postcard project/google maps mashup to see a map of the postcards.

if you're new, you can browse the archives to catch up. and don't forget to watch a few movies that i made while we were in the neonatal intensive care unit. or if you want the abridged version and you can find a copy, you can read about his adventures in the november 2005 issue of parents magazine.
