Notes for Feb 19th

Sick day in the house, so not a lot of web-browsing:

• Old, seriously old, shipwrecks.
• The physics of curling (definitely the most interesting Olympic sport).
• Paleontologists are always publishing papers about fossils and new species that, as it turns out, have been sitting in a museum for thirty years or were collected ten years back. No exception. C'mon paleontologists! Hurry it up!
