#74 – Paul Dirac: Four Lectures at Christchurch, New Zealand, 1975 – Quantum Mechanics, Quantum Electrodynamics, Magnetic Monopoles, and Does 'G' Vary? (Large Numbers Hypothesis)
Paul Adrien Maurice Dirac (8 August 1902 – 20 October 1984) was an English mathematical and theoretical physicist who is considered to be one of the founders of quantum mechanics and quantum electrodynamics. He is credited with laying the foundations of quantum field theory. He was the Lucasian Professor of Mathematics at the University of Cambridge, a professor of physics at Florida State University and the University of Miami, and a 1933 Nobel Prize in Physics recipient.
Dirac made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics, coining the latter term. Among other discoveries, he formulated the Dirac equation in 1928, which describes the behaviour of fermions and predicted the existence of antimatter, and is considered one of the most important equations in physics, with it being considered by some to be the "real seed of modern physics". He wrote a famous paper in 1931, which further predicted the existence of antimatter. Dirac shared the 1933 Nobel Prize in Physics with Erwin Schrödinger "for the discovery of new productive forms of atomic theory". He also made significant contributions to the reconciliation of general relativity with quantum mechanics. His 1930 monograph, The Principles of Quantum Mechanics, is considered to be one of the most influential texts on quantum mechanics.
Dirac's contributions were not only restricted to quantum mechanics. He contributed to the Tube Alloys project, the British programme to research and construct atomic bombs during World War II. Furthermore, Dirac made fundamental contributions to the process of uranium enrichment and the gas centrifuge, and whose work was deemed to be "probably the most important theoretical result in centrifuge technology". He also contributed to cosmology, putting forth his large numbers hypothesis. Dirac is also seen as having anticipated string theory well before its inception, with his work on the Dirac membrane and Dirac–Born–Infeld action, amongst other contributions.
Dirac was regarded by his friends and colleagues as unusual in character. In a 1926 letter to Paul Ehrenfest, Albert Einstein wrote of a Dirac paper, "I am toiling over Dirac. This balancing on the dizzying path between genius and madness is awful." In another letter concerning the Compton effect he wrote, "I don't understand the details of Dirac at all." In 1987, Abdus Salam stated that "Dirac was undoubtedly one of the greatest physicists of this or any century . . . No man except Einstein has had such a decisive influence, in so short a time, on the course of physics in this century."

#73 – John Hopfield: Artificial Neural Networks and Speech Processing (1988)
John Joseph Hopfield (born July 15, 1933) is an American scientist most widely known for his invention of an associative neural network in 1982. It is now more commonly known as the Hopfield network.
Hopfield was born in 1933 to Polish physicist John Joseph Hopfield and physicist Helen Hopfield. Helen was the older Hopfield's second wife. He is the sixth of Hopfield's children and has three children and six grandchildren of his own.
He received his A.B. from Swarthmore College in 1954, and a Ph.D. in physics from Cornell University in 1958 (supervised by Albert Overhauser). He spent two years in the theory group at Bell Laboratories, and subsequently was a faculty member at University of California, Berkeley (physics), Princeton University (physics), California Institute of Technology (chemistry and biology) and again at Princeton, where he is the Howard A. Prior Professor of Molecular Biology, emeritus. For 35 years, he also continued a strong connection with Bell Laboratories.
In 1986 he was a co-founder of the Computation and Neural Systems PhD program at Caltech.
His most influential papers have been "The Contribution of Excitons to the Complex Dielectric Constant of Crystals" (1958), describing the polariton; "Electron transfer between biological molecules by thermally activated tunneling" (1974), describing the quantum mechanics of long-range electron transfers; "Kinetic Proofreading: a New Mechanism for Reducing Errors in Biosynthetic Processes Requiring High Specificity" (1974); "Neural networks and physical systems with emergent collective computational abilities" (1982) (known as the Hopfield Network) and, with D. W. Tank, "Neural computation of decisions in optimization problems" (1985). His current research and recent papers are chiefly focused on the ways in which action potential timing and synchrony can be used in neurobiological computation.

#72 – Arthur Conan Doyle: Brief Interview on the Origins of the “Monstrous Growth” Sherlock Holmes and the Importance of Psychic Matters (1929)
Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a British writer and physician. He created the character Sherlock Holmes in 1887 for A Study in Scarlet, the first of four novels and fifty-six short stories about Holmes and Dr. Watson. The Sherlock Holmes stories are milestones in the field of crime fiction.
Doyle was a prolific writer; other than Holmes stories, his works include fantasy and science fiction stories about Professor Challenger, and humorous stories about the Napoleonic soldier Brigadier Gerard, as well as plays, romances, poetry, non-fiction, and historical novels. One of Doyle's early short stories, "J. Habakuk Jephson's Statement" (1884), helped to popularize the mystery of the Mary Celeste.

#71 – Noam Chomsky: Foundations of World Order: the UN, World Bank, IMF & Declaration of Human Rights 1999
Avram Noam Chomsky (born December 7, 1928) is an American professor and public intellectual known for his work in linguistics, political activism, and social criticism. Sometimes called "the father of modern linguistics", Chomsky is also a major figure in analytic philosophy and one of the founders of the field of cognitive science. He is a laureate professor of linguistics at the University of Arizona and an institute professor emeritus at the Massachusetts Institute of Technology (MIT). Among the most cited living authors, Chomsky has written more than 150 books on topics such as linguistics, war, and politics. Ideologically, he aligns with anarcho-syndicalism and libertarian socialism.
Born to Ashkenazi Jewish immigrants in Philadelphia, Chomsky developed an early interest in anarchism from alternative bookstores in New York City. He studied at the University of Pennsylvania. During his postgraduate work in the Harvard Society of Fellows, Chomsky developed the theory of transformational grammar for which he earned his doctorate in 1955. That year he began teaching at MIT, and in 1957 emerged as a significant figure in linguistics with his landmark work Syntactic Structures, which played a major role in remodeling the study of language. From 1958 to 1959 Chomsky was a National Science Foundation fellow at the Institute for Advanced Study. He created or co-created the universal grammar theory, the generative grammar theory, the Chomsky hierarchy, and the minimalist program. Chomsky also played a pivotal role in the decline of linguistic behaviorism, and was particularly critical of the work of B. F. Skinner.
An outspoken opponent of U.S. involvement in the Vietnam War, which he saw as an act of American imperialism, in 1967 Chomsky rose to national attention for his anti-war essay "The Responsibility of Intellectuals". Becoming associated with the New Left, he was arrested multiple times for his activism and placed on President Richard Nixon's list of political opponents. While expanding his work in linguistics over subsequent decades, he also became involved in the linguistics wars. In collaboration with Edward S. Herman, Chomsky later articulated the propaganda model of media criticism in Manufacturing Consent, and worked to expose the Indonesian occupation of East Timor. His defense of unconditional freedom of speech, including that of Holocaust denial, generated significant controversy in the Faurisson affair of the 1980s. Chomsky's commentary on the Cambodian genocide also generated controversy. Since retiring from active teaching at MIT, he has continued his vocal political activism, including opposing the 2003 invasion of Iraq and supporting the Occupy movement. An anti-Zionist, Chomsky considers Israel's treatment of Palestinians to be worse than South African-style apartheid, and criticizes U.S. support for Israel.
Chomsky is widely recognized as having helped to spark the cognitive revolution in the human sciences, contributing to the development of a new cognitivistic framework for the study of language and the mind. Chomsky remains a leading critic of U.S. foreign policy, contemporary capitalism, U.S. involvement and Israel's role in the Israeli–Palestinian conflict, and mass media.

#70 – Peter Thiel: Scruton Lectures 2023 – The Diversity Myth
Peter Andreas Thiel (born 11 October 1967) is a German-American billionaire entrepreneur, venture capitalist, and political activist. A co-founder of PayPal, Palantir Technologies, and Founders Fund, he was the first outside investor in Facebook. As of June 2023, Thiel had an estimated net worth of $9.7 billion and was ranked 213th on the Bloomberg Billionaires Index.
He worked as a securities lawyer at Sullivan & Cromwell, as a speechwriter for former U.S. Secretary of Education William Bennett and as a derivatives trader at Credit Suisse. He founded Thiel Capital Management in 1996. He co-founded PayPal with Max Levchin and Luke Nosek in 1998, serving as chief executive officer until its sale to eBay in 2002 for $1.5 billion.
After PayPal, he founded Clarium Capital, a global macro hedge fund based in San Francisco. In 2003, he launched Palantir Technologies, a big data analysis company, serving as its chairman since its inception. In 2005, he launched Founders Fund with PayPal partners Ken Howery and Luke Nosek. Earlier, Thiel became Facebook's first outside investor when he acquired a 10.2% stake for $500,000 in August 2004. He sold the majority of his shares in Facebook for over $1 billion in 2012 but remains on the board of directors. After the Fifth National Government intervened on his behalf, Thiel was controversially granted New Zealand citizenship in 2011 after spending 12 days in the country non-consecutively. He co-founded Valar Ventures in 2010; co-founded Mithril Capital, serving as investment committee chair, in 2012; and served as a part-time partner at Y Combinator from 2015 to 2017.

#69 – Bertrand Russell & Frederick Copleston: The Famous Debate Over the Existence of God (1948)
Bertrand Arthur William Russell, 3rd Earl Russell (18 May 1872 – 2 February 1970) was a British mathematician, philosopher, logician, and public intellectual. He had a considerable influence on mathematics, logic, set theory, linguistics, artificial intelligence, cognitive science, computer science, and various areas of analytic philosophy, especially philosophy of mathematics, philosophy of language, epistemology, and metaphysics.
He was one of the early 20th century's most prominent logicians and a founder of analytic philosophy, along with his predecessor Gottlob Frege, his friend and colleague G. E. Moore, and his student and protégé Ludwig Wittgenstein. Russell with Moore led the British "revolt against idealism". Together with his former teacher A. N. Whitehead, Russell wrote Principia Mathematica, a milestone in the development of classical logic and a major attempt to reduce the whole of mathematics to logic. Russell's article "On Denoting" has been considered a "paradigm of philosophy".
Russell was a pacifist who championed anti-imperialism and chaired the India League. He went to prison for his pacifism during World War I, but also saw the war against Adolf Hitler's Nazi Germany as a necessary "lesser of two evils". In the wake of World War II, he welcomed American global hegemony in favor of either Soviet hegemony or no (or ineffective) world leadership, even if it were to come at the cost of using their nuclear weapons. He would later criticize Stalinist totalitarianism, condemn the United States' involvement in the Vietnam War, and become an outspoken proponent of nuclear disarmament.
In 1950, Russell was awarded the Nobel Prize in Literature "in recognition of his varied and significant writings in which he champions humanitarian ideals and freedom of thought". He was also the recipient of the De Morgan Medal (1932), Sylvester Medal (1934), Kalinga Prize (1957), and Jerusalem Prize (1963).
Frederick Charles Copleston (10 April 1907 – 3 February 1994) was an English Roman Catholic Jesuit priest, philosopher, and historian of philosophy, best known for his influential multi-volume A History of Philosophy (1946–75).
Copleston achieved a degree of popularity in the media for debating the existence of God with Bertrand Russell in a celebrated 1948 BBC broadcast; the following year he debated logical positivism and the meaningfulness of religious language with his friend the analytic philosopher A. J. Ayer.

#68 – Michael Polanyi: Full History and Hope Lecture Series – The Destruction of Reality, The Realm of the Unspoken, The Vindication of Realities, and A Society of Explorers
Michael Polanyi (11 March 1891 – 22 February 1976) was a Hungarian-British polymath, who made important theoretical contributions to physical chemistry, economics, and philosophy. He argued that positivism is a false account of knowing.
His wide-ranging research in physical science included chemical kinetics, x-ray diffraction, and adsorption of gases. He pioneered the theory of fibre diffraction analysis in 1921, and the dislocation theory of plastic deformation of ductile metals and other materials in 1934. He emigrated to Germany, in 1926 becoming a chemistry professor at the Kaiser Wilhelm Institute in Berlin, and then in 1933 to England, becoming first a chemistry professor, and then a social sciences professor at the University of Manchester. Two of his pupils won the Nobel Prize, as well as one of his children. In 1944 Polanyi was elected to the Royal Society.
The contributions which Polanyi made to the social sciences include the concept of a polycentric spontaneous order and his rejection of a value neutral conception of liberty. They were developed in the context of his opposition to central planning.

#66 – Saul Bellow
Saul Bellow (born Solomon Bellows; June 10, 1915 – April 5, 2005) was a Canadian–American writer. For his literary work, Bellow was awarded the Pulitzer Prize, the 1976 Nobel Prize in Literature, and the National Medal of Arts. He is the only writer to win the National Book Award for Fiction three times, and he received the National Book Foundation's lifetime Medal for Distinguished Contribution to American Letters in 1990.
In the words of the Swedish Nobel Committee, his writing exhibited "the mixture of rich picaresque novel and subtle analysis of our culture, of entertaining adventure, drastic and tragic episodes in quick succession interspersed with philosophic conversation, all developed by a commentator with a witty tongue and penetrating insight into the outer and inner complications that drive us to act, or prevent us from acting, and that can be called the dilemma of our age."
His best-known works include The Adventures of Augie March, Henderson the Rain King, Herzog, Mr. Sammler's Planet, Seize the Day, Humboldt's Gift, and Ravelstein.
Bellow said that of all his characters, Eugene Henderson, of Henderson the Rain King, was the one most like himself. Bellow grew up as an immigrant from Quebec. As Christopher Hitchens describes it, Bellow's fiction and principal characters reflect his own yearning for transcendence, a battle "to overcome not just ghetto conditions but also ghetto psychoses." Bellow's protagonists wrestle with what Albert Corde, the dean in The Dean's December, called "the big-scale insanities of the 20th century." This transcendence of the "unutterably dismal" (a phrase from Dangling Man) is achieved, if it can be achieved at all, through a "ferocious assimilation of learning" (Hitchens) and an emphasis on nobility.

#65 – Margaret Mead & James Baldwin: A Rap On Race Conversation (1971)
Margaret Mead (December 16, 1901 – November 15, 1978) was an American cultural anthropologist who featured frequently as an author and speaker in the mass media during the 1960s and the 1970s.
She earned her bachelor's degree at Barnard College of Columbia University and her M.A. and Ph.D. degrees from Columbia. Mead served as president of the American Association for the Advancement of Science in 1975.
Mead was a communicator of anthropology in modern American and Western culture and was often controversial as an academic. Her reports detailing the attitudes towards sex in South Pacific and Southeast Asian traditional cultures influenced the 1960s sexual revolution. She was a proponent of broadening sexual conventions within the context of Western cultural traditions.
__________________________________________________
James Arthur Baldwin (August 2, 1924 – December 1, 1987) was an American writer and civil rights activist. He garnered acclaim for his work across several forms, including essays, novels, plays, and poems. His first novel, Go Tell It on the Mountain, was published in 1953; decades later, Time magazine included the novel on its list of the 100 best English-language novels released from 1923 to 2005. His first essay collection, Notes of a Native Son, was published in 1955.
Baldwin's work fictionalizes fundamental personal questions and dilemmas amid complex social and psychological pressures. Themes of masculinity, sexuality, race, and class intertwine to create intricate narratives that run parallel with some of the major political movements toward social change in mid-twentieth century America, such as the civil rights movement and the gay liberation movement. Baldwin's protagonists are often but not exclusively African American, and gay and bisexual men frequently feature prominently in his literature. These characters often face internal and external obstacles in their search for social and self-acceptance. Such dynamics are prominent in Baldwin's second novel, Giovanni's Room, which was written in 1956, well before the gay liberation movement.
His reputation has endured since his death and his work has been adapted for the screen to great acclaim. An unfinished manuscript, Remember This House, was expanded and adapted for cinema as the documentary film I Am Not Your Negro (2016), which was nominated for Best Documentary Feature at the 89th Academy Awards. One of his novels, If Beale Street Could Talk, was adapted into the Academy Award–winning film of the same name in 2018, directed and produced by Barry Jenkins.
In addition to writing, Baldwin was also a well-known public figure and orator, especially during the civil rights movement in the United States.
