No rest for the wicked

Didn’t I just say “Woo hoo” yesterday? False alarm. Scarcely do I clear one set of major tasks away than another set rise up. I already mentioned that I was going to be the speaker at the Humanists of Minnesota banquet on Saturday evening. I neglected to tell you all that I’m leaving for the University of Michigan tomorrow to give the keynote at the Genetic Programming Theory and Practice Workshop.

I know virtually nothing about genetic programming, so this is a wonderful opportunity to learn something about it.

Since I’m certainly not going to be able to tell them a thing about genetic programming, I’m planning to tell them a little about my own skewed perspective as one of those metazoan-centric fans of developmental processes. I’m hoping they might learn a little something from me, and that we’ll all have some fun with ideas about embryos. Here’s my very brief abstract:

A developmental biologist’s view of evolution

The ongoing integration of molecular genetics, developmental biology, and evolution (the field of evo-devo) is stirring up new ideas and new questions. I will tell a few stories from the evo-devo literature that illustrate the importance of the principles of developmental plasticity and developmental constraint on evolutionary trajectories — showing that these are two competing and complementary forces operating on multicellular organisms. My argument is that the contingencies of developmental architectures may well be as significant a force on evolutionary histories as selection.

Next week I get to slack off. No, wait, there’s also…

Mom did good work

On the old site, I had a little tradition of occasionally showing off embarrassing baby pictures of the kids (here’s Alaric, Connlann, and Skatje, for instance). Today is Mother’s Day, and it would be cool to show off old pictures of Mom, but wouldn’t you know it — mothers are much too clever for that. She just sent me a collection of baby pictures of Little PZ, so I’ll turn the magic time-machine on myself, instead.

This is pure treacle, self-obsession, vanity, and nostalgia. Don’t look below the fold.

Hello from St Cloud

It’s a bit of a travel day for me again—I’m in St Cloud, sitting in a coffee shop for a little while, before heading off to the SCSU campus for…ALARIC’S GRADUATION! My oldest son is graduating with a double major in Economics and Political Science today. One less set of tuition payments to make, at last.

OK, it’s also good that he’s going to be a free and independent adult, and isn’t going to need me for anything anymore.

Death notice

The regal old willow that has graced our front yard for longer than I’ve been alive, and which has sadly shown signs of advancing senescence, is scheduled for termination tomorrow morning. It’s a beautiful old tree, but its habit of dropping a ton of log every spring has made it a hazard, so we’ve decided to end it quickly, rather than a slow death by yearly spontaneous lopping of limbs.

I’ve had several people ask me about this tree, and several have mentioned their sorrow at its imminent passing. If you’d like to pay last respects, tonight is your last chance. Feel free to step into the yard and give it a goodbye hug (be careful, though, and don’t shake it too much—I disavow any responsibility for falling branches.)

The execution of the poor tree will be an all day job on Friday, and unfortunately, it’s got to be carried out in public. For those of you of delicate sensitivities, you might want to stay away from 3rd and College Avenue until Saturday.

In which I trade Kos for Foo

I’m a traitor. Remember how I was going to lead the Science Caucus at YearlyKos? I was really looking forward to that and we had some great ideas for a productive session. I hope who ever takes over for me can use some of that.

That’s right — I’m not going to be able to make it to YearlyKos this time around. I’m bad. I’m selfish.

What came up is an invitation to something called a Science Foo camp, sponsored by Google, O’Reilly, and Nature … and it sounds titillating enough that I just can’t turn it down. So I’m abandoning the Kossacks this time around, but I’m sure there’s enough science talent going there that I’ll be easily replaced.

Come on, it sounds like Foo camp will be nerdvana. How could I possibly miss it?

Rotten old willow

We’ve been experiencing a great howling windstorm since yesterday — it seems to be a common event every spring around here that we get a storm or two just to teach the trees that this is supposed to be prairie. Our excitement for the day is that this huge old willow in our yard lost another limb, something like what happened two years ago. At that time, a major limb smacked down on the south side of the tree; this year, an even larger branch smashed down to the north. That monster is significantly bigger around than I am.

Here’s Skatje sitting in the wreckage. She was very enthusiastic about getting out there and sawing at some of the lesser branches so we could swing the debris out of the road and the sidewalk. We’re going to have to get a professional tree service to take care of the rest.

We’ve been lucky so far — the deadfalls have paralleled the house, and no one has been under them. Looking at what’s left of the tree, the next big branch to go is either going to fall to the east and take out our car, or to the west and take out the neighbor’s garage. Old Man Willow is out to get us, we may have to terminate him first.

Woo hoo III!

Knocked another one down — I finished the grades for the last exam in my genetics course (there is still an optional final next Friday). This was an important one, because I promised myself that if I could get them all done this afternoon, I would let myself go to the local theater to watch Spiderman 3 tonight. Those little internal incentives help a lot!
