Friday assorted links

1. Why is Russia escalating in Ukraine?

2. Those new service sector jobs: consultant to autodidact physicists.

3. Do Greenland sharks live for 400 years?  And it seems they don’t reach sexual maturity until 150, and their age is dated with reference to the “golden age” of nuclear bomb testing.

4. “About your cat(s)…”

5. “Zhang’s parents apparently allow him to carry the doll but are still very insistent that he should still get married.”

6. Yes, yes The Great Satan but John Cochrane is right too.
