Spielberg's next film, Schindler's List, was based on the true story of Oskar Schindler, a man who risked his life to save 1,100 Jews from the Holocaust. Schindler's List earned Spielberg his first Academy Award for Best Director (it also won Best Picture). With the film a huge success at the box office, Spielberg used the profits to set up the Shoah Foundation, a non-profit organization that archives filmed testimony of Holocaust survivors. In 1997, the American Film Institute listed it among the 10 Greatest American Films ever Made (#9) which moved up to (#8) when the list was remade in 2007.
In what year was the Shoah Foundation set up?

The College's endowment is sub-divided into three distinct portfolios: (i) Unitised Scheme a unit trust vehicle for College, Faculties and Departments to invest endowments and unfettered income to produce returns for the long term; (ii) Non-Core Property a portfolio containing around 120 operational and developmental properties which College has determined are not core to the academic mission; and (iii) Strategic Asset Investments containing College's shareholding in Imperial Innovations and other restricted equity holdings. During the year 2014/15, the market value of the endowment increased by 78 million (18%) to 512.4 million on 31 July 2015.
How many nonoperational and development properties were in the portfolio?

The first landing was followed by another, precision landing on Apollo 12 in November 1969. NASA had achieved its first landing goal with enough Apollo spacecraft and Saturn V launchers left for eight follow-on lunar landings through Apollo 20, conducting extended-endurance missions and transporting the landing crews in Lunar Roving Vehicles on the last five. They also planned an Apollo Applications Program to develop a longer-duration Earth orbital workshop (later named Skylab) to be constructed in orbit from a spent S-IVB upper stage, using several launches of the smaller Saturn IB launch vehicle. But planners soon decided this could be done more efficiently by using the two live stages of a Saturn V to launch the workshop pre-fabricated from an S-IVB (which was also the Saturn V third stage), which immediately removed Apollo 20. Belt-tightening budget cuts soon led NASA to cut Apollo 18 and 19 as well, but keep three extended/Lunar Rover missions. Apollo 13 encountered an in-flight spacecraft failure and had to abort its lunar landing in April 1970, returning its crew safely but temporarily grounding the program again. It resumed with four successful landings on Apollo 14 (February 1971), Apollo 15 (July 1971), Apollo 16 (April 1972), and Apollo 17 (December 1972).
Apollo 15 landed on the Moon on what date?
A: July 1971

Among Peirce's major contributions was to place inductive reasoning and deductive reasoning in a complementary rather than competitive mode, the latter of which had been the primary trend among the educated since David Hume wrote a century before. To this, Peirce added the concept of abductive reasoning. The combined three forms of reasoning serve as a primary conceptual foundation for the empirically based scientific method today. Peirce's approach "presupposes that (1) the objects of knowledge are real things, (2) the characters (properties) of real things do not depend on our perceptions of them, and (3) everyone who has sufficient experience of real things will agree on the truth about them. According to Peirce's doctrine of fallibilism, the conclusions of science are always tentative. The rationality of the scientific method does not depend on the certainty of its conclusions, but on its self-corrective character: by continued application of the method science can detect and correct its own mistakes, and thus eventually lead to the discovery of truth".
When was the doctrine of fallibilism published?
