Wellnigh an infinity of reader e-mails along these lines following my Einstein post.

[Reader A] Mr. Derbyshire — You wrote: “Does he have a car-thief brother named Schrödinger?” His brother may or may not have a stolen car in his possession, and we can of course only know once we have arrested him.[Reader B] Derb: Einstein Laibhen did have a brother named Schrödinger. But he might be dead, we don’t know for sure.

Those who understand, will understand.

Also a lot ot these:

[Reader C] Mr. D — I think you may have missed the best part about the story of the thugs crashing the $50,000 Sweet Sixteen birthday party: the birthday girl’s parents — a city cop and a transit worker. I think we went out for pizza on my daughters 16th.

Pizza? What a cheapskate! We took Nellie to TGI Fridays & let her order extra cheesecake. The Derbs live large when occasion demands.

[Reader D] John, Far more worrying than the ethnicity of the assailants are the occupations of the parents, a “city cop and transit worker” respectively. When your “public servants” can shell out $50K for a birthday party, the fiscal outlook for NY is grim grim grim.

Well, it’s grim grim grim if you’re not working for the city. Once again, readers, be sure to tell your children at least once every day: GET A GOVERNMENT JOB!
