Two on Tuesday

I'm working hard on grading finals and getting my semester grades done and calculated. I will have much blathering to do after I get the semester wrapped up. I'm behind on everything at the moment. The garden is in complete weedy shambles, but I have to get my grades done NOW!

Two interesting little tidbits:

1. Messages from your brain travel along your nerves at up to 200 miles an hour.

2. In outer space, liquids become sphere-shaped.
