Question: This law is a fundamental principle of physics. As shown rigorously by Noether's theorem, the conservation of energy is a mathematical consequence of translational symmetry of time, a property of most phenomena below the cosmic scale that makes them independent of their locations on the time coordinate. Put differently, yesterday, today, and tomorrow are physically indistinguishable. This is because energy is the quantity which is canonical conjugate to time. This mathematical entanglement of energy and time also results in the uncertainty principle - it is impossible to define the exact amount of energy during any definite time interval. The uncertainty principle should not be confused with energy conservation - rather it provides mathematical limits to which energy can in principle be defined and measured.
Is there an answer to this question: What shows that the conservation of energy is a mathematical consequence of translational symmetry of time?

Answer: Noether's theorem


Question: Agriculture and food and drink production continue to be major industries in the county, employing over 15,000 people. Apple orchards were once plentiful, and Somerset is still a major producer of cider. The towns of Taunton and Shepton Mallet are involved with the production of cider, especially Blackthorn Cider, which is sold nationwide, and there are specialist producers such as Burrow Hill Cider Farm and Thatchers Cider. Gerber Products Company in Bridgwater is the largest producer of fruit juices in Europe, producing brands such as "Sunny Delight" and "Ocean Spray." Development of the milk-based industries, such as Ilchester Cheese Company and Yeo Valley Organic, have resulted in the production of ranges of desserts, yoghurts and cheeses, including Cheddar cheese—some of which has the West Country Farmhouse Cheddar Protected Designation of Origin (PDO).
Is there an answer to this question: Where is the Ilchester Cheese Company cheese sold?

Answer: unanswerable


Question: In 1971, the United States Department of Health, Education, and Welfare approached Marvel Comics editor-in-chief Stan Lee to do a comic book story about drug abuse. Lee agreed and wrote a three-part Spider-Man story portraying drug use as dangerous and unglamorous. However, the industry's self-censorship board, the Comics Code Authority, refused to approve the story because of the presence of narcotics, deeming the context of the story irrelevant. Lee, with Goodman's approval, published the story regardless in The Amazing Spider-Man #96–98 (May–July 1971), without the Comics Code seal. The market reacted well to the storyline, and the CCA subsequently revised the Code the same year.
Is there an answer to this question: What issue was Marvel asked to tackle for this agency?

Answer: drug abuse
