Question:
General relativity includes a dynamical spacetime, so it is difficult to see how to identify the conserved energy and momentum. Noether's theorem allows these quantities to be determined from a Lagrangian with translation invariance, but general covariance makes translation invariance into something of a gauge symmetry. The energy and momentum derived within general relativity by Noether's presecriptions do not make a real tensor for this reason. Einstein argued that this is true for fundamental reasons, because the gravitational field could be made to vanish by a choice of coordinates. He maintained that the non-covariant energy momentum pseudotensor was in fact the best description of the energy momentum distribution in a gravitational field. This approach has been echoed by Lev Landau and Evgeny Lifshitz, and others, and has become standard. The use of non-covariant objects like pseudotensors was heavily criticized in 1917 by Erwin Schrodinger and others. After reading the above, is "1971" the correct answer to the question "When did the standard approach to energy momentum become criticized?"?

Answer:
no

Question:
Grande dame of cooking still going strong at 90: Julia Child celebrates in San Francisco. How does it feel to turn 90 and have attained the status of an icon, a living legend? "It feels just like it felt before," Julia Child says with the throaty laugh familiar to millions who cut their culinary teeth on her "French Chef" television series. The show, along with her seminal book, "Mastering the Art of French Cooking" (1961), revolutionized the way America cooks and eats. While making light of the difference a day -- or another decade -- makes, Child intends to enjoy her birthday thoroughly. First, there will be all the public observances, including a sold-out dinner Thursday at San Francisco's tony Fifth Floor restaurant, which -- like dinners that night at 19 other venues across the country -- will benefit the scholarship fund of the International Association of Culinary Professionals (which Child co-founded). Friday to Sunday, the action moves to Napa, with both members-only and public events at COPIA: The American Center for Wine, Food and the Arts, of which she is an honorary board member. Aug. 15, her actual birthday, will see her in Maine at an annual gathering of nieces, nephews, their offspring and friends, who for many years have rolled a joined birthday celebration for several members of the group into a jolly reunion. The schedule Child and her assistant of 14 years, former pastry chef Stephanie Hersh, have laid out is not exactly a senior-citizen routine, even though Child has always been candid about her age and realistic in assessing her own capabilities. When the Pasadena native moved back to California from her long-time home in the Boston area last year, she also made the move from a condominium she and her late husband, Paul, had purchased many years ago to a progressive retirement home. She is in the most active of the four levels available, but should the need arise, she can move on to assisted living facilities within the same complex. After reading the above, is "Maine and California" the correct answer to the question "What two states is Child celebrating her 90th birthday with fans or family members?"?

Answer:
yes

Question:
When he was at Oxford he had been well known for concealing under a slightly rowdy exterior the highest spirits of any of the undergraduates. He was looked upon as the most fascinating of _farceurs_. It seems that he had distinguished himself there less for writing Greek verse, though he was good at it, than for the wonderful variety of fireworks that he persistently used to let off under the dean's window. It was this fancy of his that led, first, to his popularity, and afterwards to the unfortunate episode of his being sent down; soon after which he had married privately, chiefly in order to send his parents an announcement of his wedding in _The Morning Post_, as a surprise. Some people had come in after dinner--for there was going to be a little _sauterie intime_, as Mrs Mitchell called it, speaking in an accent of her own, so appalling that, as Vincy observed, it made it sound quite improper. Edith watched, intensely amused, as she saw that there were really one or two people present who, never having seen Mitchell before, naturally did not recognise him now, so that the disguise was considered a triumph. There was something truly agreeable in the deference he was showing to a peculiarly yellow lady in red, adorned with ugly real lace, and beautiful false hair. She was obviously delighted with the Russian prince. After reading the above, is "Vincy" the correct answer to the question "What is the name of the Russian prince?"?

Answer:
no
