Planetary infestations

Posted by Arcane Gazebo at 3:58 PM

Stephen Hawking proposes that humans need to begin colonizing other planets in order to ensure the survival of the species. Now, I don't normally approve of beating up a man in a wheelchair, but I definitely enjoyed the verbal thrashing delivered to Hawking by Chris Clarke:

Let’s say you had a horrible cockroach infestation, and the bugs were trashing your house, spreading filth and eating the bindings of your irreplaceable antique books and breeding profligately and an electrician came to you one day and told you that they were eating your circuit breaker insulation, and you needed to do something about it or your house would burn down.

I don’t know about you, but my first reaction would not be to put a bunch of roaches in a Tupperware container and then release them into a neighbor’s house so that the species would live on.

We are the problem here.


The whole post is definitely worth reading.

Colloquium Blogging: Steve Koonin on the Energy Situation

Posted by Arcane Gazebo at 8:57 PM

Some of you know Steve Koonin from his days as Caltech's provost. He's now chief scientist at BP International, and gave the colloquium at Berkeley today under the title "A Physicist's View of the World's Energy Situation". The talk was extremely interesting and seemed like a very realistic assessment. Some of the points I took away (in a bit of random order):


The talk will eventually appear here as a webcast. I've been increasingly interested in energy issues lately and I found it to be a fascinating look at how the oil companies (or at least one of them) look at these things. Next week while I'm traveling I'll read Out of Gas and see what Koonin's fellow Caltech prof David Goodstein has to say about this. (Goodstein is clearly more pessimistic.)
