Context and question: Hayek is widely recognised for having introduced the time dimension to the equilibrium construction and for his key role in helping inspire the fields of growth theory, information economics, and the theory of spontaneous order. The "informal" economics presented in Milton Friedman's massively influential popular work Free to Choose (1980), is explicitly Hayekian in its account of the price system as a system for transmitting and co-ordinating knowledge. This can be explained by the fact that Friedman taught Hayek's famous paper "The Use of Knowledge in Society" (1945) in his graduate seminars.
Which of Hayek's works did Friedman once teach?
Answer: The Use of Knowledge in Society
Context and question: Spielberg next directed the historical drama film Lincoln, starring Daniel Day-Lewis as United States President Abraham Lincoln and Sally Field as Mary Todd Lincoln. Based on Doris Kearns Goodwin's bestseller Team of Rivals: The Political Genius of Abraham Lincoln, the film covered the final four months of Lincoln's life. Written by Tony Kushner, the film was shot in Richmond, Virginia, in late 2011, and was released in the United States by Disney in November 2012. The film's international distribution was handled by 20th Century Fox. Upon release, Lincoln received widespread critical acclaim, and was nominated for twelve Academy Awards (the most of any film that year) including Best Picture and Best Director for Spielberg. It won the award for Best Production Design and Day-Lewis won the Academy Award for Best Actor for his portrayal of Lincoln, becoming the first three time winner in that category as well as the first to win for a performance directed by Spielberg.
Where was 'Lincoln' filmed?
Answer: Richmond, Virginia
Context and question: The thermionic triode, a vacuum tube invented in 1907, enabled amplified radio technology and long-distance telephony. The triode, however, was a fragile device that consumed a lot of power. Physicist Julius Edgar Lilienfeld filed a patent for a field-effect transistor (FET) in Canada in 1925, which was intended to be a solid-state replacement for the triode. Lilienfeld also filed identical patents in the United States in 1926 and 1928. However, Lilienfeld did not publish any research articles about his devices nor did his patents cite any specific examples of a working prototype. Because the production of high-quality semiconductor materials was still decades away, Lilienfeld's solid-state amplifier ideas would not have found practical use in the 1920s and 1930s, even if such a device had been built. In 1934, German inventor Oskar Heil patented a similar device.
Why were field-effect transistors not practical without high quality semiconductor materials?
