Problem: While there is some dispute as to the matter of influence, Popper had a long-standing and close friendship with economist Friedrich Hayek, who was also brought to the London School of Economics from Vienna. Each found support and similarities in the other's work, citing each other often, though not without qualification. In a letter to Hayek in 1944, Popper stated, "I think I have learnt more from you than from any other living thinker, except perhaps Alfred Tarski." Popper dedicated his Conjectures and Refutations to Hayek. For his part, Hayek dedicated a collection of papers, Studies in Philosophy, Politics, and Economics, to Popper, and in 1982 said, "...ever since his Logik der Forschung first came out in 1934, I have been a complete adherent to his general theory of methodology."
In which year did Popper write Hayek a letter expressing his intellectual debt to him?

Answer: 1944

Problem: Critics of the modern concept of the "separation of church and state" argue that it is untethered to anything in the text of the constitution and is contrary to the conception of the phrase as the Founding Fathers understood it. Philip Hamburger, Columbia Law school professor and prominent critic of the modern understanding of the concept, maintains that the modern concept, which deviates from the constitutional establishment clause jurisprudence, is rooted in American anti-Catholicism and Nativism.[citation needed] Briefs before the Supreme Court, including by the U.S. government, have argued that some state constitutional amendments relating to the modern conception of separation of church and state (Blaine Amendments) were motivated by and intended to enact anti-Catholicism.
What school is Philip Hamburger associated with?

Answer: Columbia Law school

Problem: Semi-additive is the most common process: The unpatterned board has a thin layer of copper already on it. A reverse mask is then applied. (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces.) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied. The mask is stripped away and a brief etching step removes the now-exposed bare original copper laminate from the board, isolating the individual traces. Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards.
Fully additive is the most common what?
