Chris Christie quotes rock group The Eagles in criticizing Teachers Unions

At a town hall meeting in Robinsville, NJ, Governor Christie, a self-proclaimed "Bruce Springsteen fanatic," quoted another classic rock group:

"This is not about teachers... my argument is not with the teachers of New Jersey. My argument is with the Union... who collects $730 a year in mandatory dues. And if you don't want to join the Union, here's your option. You can be out. You pay 85% of that $730 to be out of the Union.

It's like the Hotel California, you know. You can check in any time you like, but you can never leave."

Sizing a boiler?

I know someone looking for an engineer to size a boiler system to replace several hot water heaters in an apartment building.

I guess you would need to establish BTU requirement through heat loss calculation.

Out of (16) units, I would guess that no more than (8) units would

Respect for a Battered Beauty

Tom’s post yesterday about the asteroid hitting Jupiter got me looking at the Jovian system, and since my mind was on impact craters (I’ve been looking at Mercury) I went straight to Callisto.  Here’s a really cool image of Callisto taken by Cassini December 7, 2000.  Callisto is the lower left, and that’s Europa by the Great Red Spot.

What’s with Callisto, anyway?  From a distance she doesn’t look too bad, but close up the poor thing looks beat to pieces.  Battered though Callisto may be, it’s easy to see the ghostly beauty of Jupiter’s 4th Galilean moon.

As it happens, Callisto’s surface is extremely old.  Scientists estimate its surface age is about 4 billion years old.  It doesn’t experience plate tectonics or vulcanism, which would work to smooth out impact craters (like it does on Earth).  Its surface is a pretty faithful record of its battered past.  Callisto has the oldest surface in the Solar System.

Now, before you start thinking of Callisto as a dead and boring hunk of rock (with a lot of potholes), get this; NASA has good reason to believe there is a subsurface salt-water ocean on Callisto.

It also has a thin atmosphere of carbon dioxide and molecular oxygen.

Callisto is distant enough from Jupiter that it doesn’t receive as much radiation from the planet as the other Galilean moons.  If we ever establish a residential base in the Jovian system, it’ll probably be on Callisto.  Can you imagine exploring the surface?  That’s a 4 billion year old record of activity in our solar system.

The enlargement of this image is spectacular, by the way.

In spite of its liquid ocean, Callisto is not considered to be a good candidate to support life.  We’ll still look to Europa for that, and we’ll probably be sitting on Callisto while we’re looking.

I’d say it’s far from being a dead, boring hunk of rock.
