I spent several hours on Sunday afternoon in what has to be the most charming cemetery in New York City. If I didn’t know what I was looking for, I would have missed its arched iron gate, tucked into 2nd Avenue just north of East 2nd Street, where the East Village meets the Lower East Side.

Richard and Temple Grandin have co-authored a book, The Autistic Brain: Thinking Across the Spectrum, which is just out and which you should definitely and immediately buy. Before you do, Jessa and Ann have some questions. Ann: Richard, this subject is a departure for you. What is the subject, anyway? Richard: The immediate subject is the […]
Correction: An article yesterday about a tiny force in quantum mechanics that could be used in future microscopic devices referred incorrectly in some copies to the size of the force measured when two metal plates were placed within one 40-thousandth of an inch of each other. It was one 300-millionth of an ounce, not one 300-thousandth. […]

You probably know this. In August, 1939, Einstein wrote a letter to the American government. German scientists had announced that the energy holding an atom together could be released – in fact, 2.2 pounds-worth of uranium atoms would equal 10,000 tons of TNT. Einstein said this implied a new kind of bomb that Hitler’s government […]
In the first week of September 1942, 29-year-old Libertas Schultze-Boysen waited desperately for word of her husband Harro, an official in the Reich Aviation Ministry in Berlin.
