Context and question: There are three primary shopping centers in the Bronx: The Hub, Gateway Center and Southern Boulevard. The Hub–Third Avenue Business Improvement District (B.I.D.), in The Hub, is the retail heart of the South Bronx, located where four roads converge: East 149th Street, Willis, Melrose and Third Avenues. It is primarily located inside the neighborhood of Melrose but also lines the northern border of Mott Haven. The Hub has been called "the Broadway of the Bronx", being likened to the real Broadway in Manhattan and the northwestern Bronx. It is the site of both maximum traffic and architectural density. In configuration, it resembles a miniature Times Square, a spatial "bow-tie" created by the geometry of the street. The Hub is part of Bronx Community Board 1.
What is the main retail area of the South Bronx?
Answer: The Hub–Third Avenue Business Improvement District
Context and question: Pitt's Act was deemed a failure because it quickly became apparent that the boundaries between government control and the company's powers were nebulous and highly subjective. The government felt obliged to respond to humanitarian calls for better treatment of local peoples in British-occupied territories. Edmund Burke, a former East India Company shareholder and diplomat, was moved to address the situation and introduced a new Regulating Bill in 1783. The bill was defeated amid lobbying by company loyalists and accusations of nepotism in the bill's recommendations for the appointment of councillors.
What kind of calls did the government ignore?
Answer: unanswerable
Context and question: In quantum mechanics and quantum field theory, the vacuum is defined as the state (that is, the solution to the equations of the theory) with the lowest possible energy (the ground state of the Hilbert space). In quantum electrodynamics this vacuum is referred to as 'QED vacuum' to distinguish it from the vacuum of quantum chromodynamics, denoted as QCD vacuum. QED vacuum is a state with no matter particles (hence the name), and also no photons. As described above, this state is impossible to achieve experimentally. (Even if every matter particle could somehow be removed from a volume, it would be impossible to eliminate all the blackbody photons.) Nonetheless, it provides a good model for realizable vacuum, and agrees with a number of experimental observations as described next.
why is a QED vacuum impossible to achieve ?
Answer:
impossible to eliminate all the blackbody photons
