And one by one they disappear

And at last now the mathematics blog.

After getting to the gift shop, and getting some hot chocolate, we went back around the zoo a couple times, albeit taking fewer pictures this time around. Here's the evidence.

Going back through the zoo and also to see some things we had missed before. This is the great illuminated path leading past the otters, I believe.

The two swan figures are among the oldest still at the Wonderland of Lights. The ballet dancer is only a couple years old.

It's a great illuminated figure of a ballet dancer and I just regret the line holding the head steady makes it look like the figure's being hung. They need darker thread.

Here I just like how there's lights at every possible distance from the camera.

The skating bear figures sure seem like they should also be at Crossroads Village, although I don't think there are ones quite like this there. I think Bronner's has these too.

Looking up into the trees above those skating bear figures because I loved the way they arched like lightning against the black sky.

Trivia: In applying for the 1978 astronaut selection group Anna Fisher learned the position would pay about a quarter of what she earned as an emergency room physician in the Los Angeles area.
Source: The Astronaut Maker: How One Mysterious Engineer Ran Human Spaceflight for a Generation, Michael Cassutt. (She applied and, in 1984, became the first mother in space. Her husband William Fisher also applied, was selected for the 1980 group, and flew in 1985.)

Currently Reading: Pierre-Simon LaPlace, 1749 - 1827, A Life In Exact Science, Charles Coulson Gillispie with Robert Fox and Ivor Grattan-Guinness. Although I picked up the book from the university library's solidly Q143 mathematics shelves I didn't realize it was going to start with mathematical topics, like, giving out sketches of work Laplace did in differential equations, rather than the usual, like, what we can tell about where he went to school. Bracing start!
