input: Goodall had always been passionate about animals and Africa, which brought her to the farm of a friend in the Kenya highlands in 1957. From there, she obtained work as a secretary, and acting on her friend's advice, she telephoned Louis Leakey, the notable Kenyan archaeologist and palaeontologist, with no other thought than to make an appointment to discuss animals. Leakey, believing that the study of existing great apes could provide indications of the behaviour of early hominids, was looking for a chimpanzee researcher, though he kept the idea to himself. Instead, he proposed that Goodall work for him as a secretary. After obtaining approval from his wife Mary Leakey, Louis sent Goodall to Olduvai Gorge in Tanzania, where he laid out his plans. In 1958, Leakey sent Goodall to London to study primate behaviour with Osman Hill and primate anatomy with John Napier. Leakey raised funds, and on 14 July 1960, Goodall went to Gombe Stream National Park, becoming the first of what would come to be called The Trimates. She was accompanied by her mother, whose presence was necessary to satisfy the requirements of David Anstey, chief warden, who was concerned for their safety; Tanzania was "Tanganyika" at that time and a British protectorate. Leakey arranged funding and in 1962, he sent Goodall, who had no degree, to Cambridge University. She went to Newnham College, and obtained a PhD degree in ethology. She became the eighth person to be allowed to study for a PhD there without first having obtained a BA or BSc. Her thesis was completed in 1965 under the tutorship of Robert Hinde, titled Behaviour of free-living chimpanzees, detailing her first five years of study at the Gombe Reserve.

input: Weston always made contact prints, meaning that the print was exactly the same size as the negative. This was essential for the platinum printing that he preferred early in his career, since at that time the platinum papers required ultra-violet light to activate. Weston did not have an artificial ultra-violet light source, so he had to place the contact print directly in sunlight in order to expose it. This limited him to printing only on sunny days. When he wanted a print that was larger than the original negative size, he used an enlarger to create a larger inter-positive, then contact printed it to a new negative. The new larger negative was then used to make a print of that size. This process was very labor-intensive; he once wrote in his Daybooks "I am utterly exhausted tonight after a whole day in the darkroom, making eight contact negatives from the enlarged positives." In 1924 Weston wrote this about his darkroom process, "I have returned, after several years use of Metol-Hydroquinine open-tank" developer to a three-solution Pyro developer, and I develop one at a time in a tray instead of a dozen in a tank." Each sheet of film was viewed under either a green or an orange safelight in his darkroom, allowing him to control the individual development of a negative. He continued to use this technique for the rest of his life. Weston was known to extensively use dodging and burning to achieve the look he wanted in his prints.

input: Sowell has also written a trilogy of books on ideologies and political positions, including A Conflict of Visions, where he speaks about the origins of political strife; The Vision of the Anointed, where he compares the conservative/libertarian and liberal/progressive worldviews; and The Quest for Cosmic Justice, where, as in many of his other writings, he outlines his thesis of the need for intellectuals, politicians and leaders to fix and perfect the world in utopian, and ultimately he posits, disastrous fashions. Separate from the trilogy, but also in discussion of the subject, he wrote Intellectuals and Society, where, building on his earlier work, he discusses what he argues to be the blind hubris and follies of intellectuals in a variety of areas. Sowell challenges the notion that black progress is due to progressive government programs or policies, in The Economics and Politics of Race, (1983), Ethnic America (1981), Affirmative Action Around the World (2004), and other books. He claims that many problems identified with blacks in modern society are not unique, either in terms of American ethnic groups, or in terms of a rural proletariat struggling with disruption as it became urbanized, as discussed in his book Black Rednecks and White Liberals (2005). In Affirmative Action Around the World Sowell holds that affirmative action covers most of the American population, particularly women, and has long since ceased to favor blacks. Sowell described his serious study of Karl Marx in his autobiography. He opposes Marxism, providing a critique in his book Marxism: Philosophy and Economics (2011). Sowell also favors decriminalization of all drugs.
