Einstein and Tensor Calculus

What a shame that Dennis Overbye's story about the General Theory of Relativity didn't mention the mathematical foundation for Einstein's work. The General Theory could not have been developed without Tensor Calculus, which makes possible modeling of complex motion in uneven space. Tenor calculus is so difficult even Einstein needed a tutor, his friend mathematician Marcel Grossman, "Between the years of 1915 to 1919, Einstein held a correspondence with the Italian mathematician Tullio Levi-Civita – who in 1900 published perhaps the most important work on tensor calculus to this very day - who desired to help him [Einstein] fix some mathematical errors he had found in Einstein’s work."

NY Times Features War Criminal Simon Winchester

The Times story concerning the arrest of a British soldier for the Bloody Sunday Massacre makes no mention of the role their featured contributor, Simon Winchester (e.g., 11/6/2015), played in the media cover-up of the murders.  The only thing The Times should be featuring from Winchester is an apology for his complicity in British war crimes in Northern Ireland.

"The final London edition of the Guardian (February 6th, 1971) said that, 'an army marksman shot dead one rioter, who threw two petrol bombs at an armoured car in Butler Street, off Crumlin Road, Belfast. The dead man was Bernard Watt, aged 28, of Hooker Street'. The report was headed 'by Simon Winchester'. On April 6th Bernadette Devlin raised this report in the House of Commons and alleged that it had been 'concocted in the editorial offices of the Guardian, to condone the cold blooded murder of one, Barney Watt.'

Mr. Winchester's claim to fame rests on a book about a "mad" Oxford dictionary contributor.  The "madman" escaped the gallows according to Mr. Winchester because he was driven mad by having  to witness an Irish deserter, one of many according to Winchester, being branded.   This made for a good story, but as Mr. Winchester surely knew,  since he reviewed the military records of the "madman",  the "madman" wasn't anywhere near where the battle and alleged (imaginary) branding took place.  Moreover, as Mr. Winchester and his editors knew, branding wasn't a Civil War punishment for desertion.   The "deserter" story was just a cock-and-bull excuse dreamed up for a gullible English jury to absolve a rich drunk for shooting a hapless passerby.
