In 'To Explain the World', Steven Weinberg provides a rich and irreverent history of science, tracing its evolution from ancient Miletus to the scientific revolution of Copernicus, Galileo, and Newton. The book examines the struggles and breakthroughs that led to the emergence of modern science, highlighting interactions between science, religion, technology, and philosophy. Weinberg's narrative offers a unique perspective on how science has shaped human understanding and development.
Galileo Galilei's 'Two New Sciences' is a seminal work published in 1638, which laid the groundwork for modern physics by discussing the strength of materials and the motion of objects. The book is structured as a dialogue between three characters and explores topics such as uniform motion, accelerated motion, and projectile motion, setting the stage for later scientific developments.
This book is an edited collection of reminiscences by Richard Feynman, based on recorded audio conversations he had with his friend and drumming partner Ralph Leighton. It covers a variety of instances in Feynman's life, including his work on the Manhattan Project, his critique of the science education system in Brazil, and his various hobbies such as safe-cracking, painting, and playing the bongo drums. The book also includes his famous 'Cargo Cult Science' lecture, where he cautions against the superficial appearance of scientific investigation without a self-critical attitude. Feynman's stories are lighthearted yet insightful, reflecting his high intelligence, curiosity, and humor.
Tim Maudlin is Professor of Philosophy at NYU and Founder and Director of the John Bell Institute for the Foundations of Physics. This is Tim’s seventh appearance on the show. He last appeared on episode 237 for a masterclass on Albert Einstein’s theory of special relativity, explaining it from the ground up and elucidating some common misconceptions. In this episode Tim returns for a discussion of another of Einstein’s major impacts on physics: his theory of general relativity. More particularly, Tim and Robinson discuss black holes, time, paradoxes of distance, Penrose diagrams, figures like Leonard Susskind and Richard Feynman, the curvature of space, and more. If you’re interested in the foundations of physics, then please check out the JBI, which is devoted to providing a home for research and education in this important area. Any donations are immensely helpful at this early stage in the institute’s life.
