[Q]: 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. <sep>When did the standard approach to energy momentum become criticized?<sep>1911
[A]: Yes

[Q]: New Horizons: Exhausted after the Civil War, Spain remained on the sidelines during World War II and began to recover economically under the oppressive, law-and-order regime of Franco. There had been a foretaste of elite foreign tourism in the 1920s, but it was the late 1950s when the rest of Europe began sun-seeking pilgrimages to Spain. Tourism exploded into an annual southern migration, transforming the Spanish economy, landscape, and society. Eager to capitalize, the country poured its soul into mass tourism, which triggered a rash of indiscriminate building on the southern and eastern coastlines, with scant regard for tradition or aesthetics. But after so many years closed off from the rest of Europe, of equal significance was the injection of foreign influences into Franco's once hermetically sealed Spain. Mallorca and Menorca in particular saw explosive growth in tourism; by the 1970s, the Balearics were one of Europe's most popular holiday destinations. Franco named as his successor the grandson of Alfonso XIII, who was enthroned as King Juan Carlos I when the dictator died in 1975. To the dismay of Franco diehards, the king brilliantly managed the transition to democracy, then stood back to allow it full rein, even intervening during a brief attempt at a military coup. After many years of repression, new freedoms and autonomy were granted to Spanish regions, including the Balearics, and their languages and cultures enjoyed a long-desired renaissance. More a part of Europe than ever before, Spain joined the European Community (now European Union) in 1986, giving further boost to a booming economy. The tourist industry continued to expand, and though it became one of the top two income earners in Spain, a realization that unrestricted mass tourism was leading to damaging long-term consequences also began to grow. By the late 1990s, a new emphasis on quality and, especially in the Balearics, on safeguarding the environment had finally taken roottoo late for many environmentalists, but hopefully still in time to preserve much of the natural beauty and unique character of the Las Islas Baleares. <sep>Why was Spain so isolated and what event happened that allowed Mallorca and Menorca to see explosions in tourism?<sep>Spain was surrounded by enemies
[A]: No

[Q]: The day was just breaking, as I left the tower; though it was still too dark in the house to be able to see without a light, and I took one of the study candles with me on my 'round. By the time I had finished the ground floor, the daylight was creeping in, wanly, through the barred windows. My search had shown me nothing fresh. Everything appeared to be in order, and I was on the point of extinguishing my candle, when the thought suggested itself to me to have another glance 'round the cellars. I had not, if I remember rightly, been into them since my hasty search on the evening of the attack. For, perhaps, the half of a minute, I hesitated. I would have been very willing to forego the task--as, indeed, I am inclined to think any man well might--for of all the great, awe-inspiring rooms in this house, the cellars are the hugest and weirdest. Great, gloomy caverns of places, unlit by any ray of daylight. Yet, I would not shirk the work. I felt that to do so would smack of sheer cowardice. Besides, as I reassured myself, the cellars were really the most unlikely places in which to come across anything dangerous; considering that they can be entered, only through a heavy oaken door, the key of which, I carry always on my person. <sep>Why wouldn't you search the cellar?<sep>It is scary
[A]:
Yes
