Drawing Theories Apart


Book Description

Winner of the 2007 Pfizer Prize from the History of Science Society. Feynman diagrams have revolutionized nearly every aspect of theoretical physics since the middle of the twentieth century. Introduced by the American physicist Richard Feynman (1918-88) soon after World War II as a means of simplifying lengthy calculations in quantum electrodynamics, they soon gained adherents in many branches of the discipline. Yet as new physicists adopted the tiny line drawings, they also adapted the diagrams and introduced their own interpretations. Drawing Theories Apart traces how generations of young theorists learned to frame their research in terms of the diagrams—and how both the diagrams and their users were molded in the process. Drawing on rich archival materials, interviews, and more than five hundred scientific articles from the period, Drawing Theories Apart uses the Feynman diagrams as a means to explore the development of American postwar physics. By focusing on the ways young physicists learned new calculational skills, David Kaiser frames his story around the crafting and stabilizing of the basic tools in the physicist's kit—thus offering the first book to follow the diagrams once they left Feynman's hands and entered the physics vernacular.




Julian Schwinger: The Physicist, The Teacher, And The Man


Book Description

In the post-quantum-mechanics era, few physicists, if any, have matched Julian Schwinger in contributions to and influence on the development of physics. A deep and provocative thinker, Schwinger left his indelible mark on all areas of theoretical physics; an eloquent lecturer and immensely successful mentor, he was gentle, intensely private, and known for being “modest about everything except his physics”. This book is a collection of talks in memory of him by some of his contemporaries and his former students: A Klein, F Dyson, B DeWitt, W Kohn, D Saxon, P C Martin, K Johnson, S Deser, R Finkelstein, Y J Ng, H Feshbach, L Brown, S Glashow, K A Milton, and C N Yang. From it, one can get a glimpse of Julian Schwinger, the physicist, the teacher, and the man. Altogether, this book is a must for all physicists, physics students, and others who are interested in great legends.

How the Hippies Saved Physics: Science, Counterculture, and the Quantum Revival


Book Description

"How the Hippies Saved Physics gives us an unconventional view of some unconventional people engaged early in the fundamentals of quantum theory. Great fun to read." —Anton Zeilinger, Nobel laureate in physics The surprising story of eccentric young scientists—among them Nobel laureates John Clauser and Alain Aspect—who stood up to convention and changed the face of modern physics. Today, quantum information theory is among the most exciting scientific frontiers, attracting billions of dollars in funding and thousands of talented researchers. But as MIT physicist and historian David Kaiser reveals, this cutting-edge field has a surprisingly psychedelic past. How the Hippies Saved Physics introduces us to a band of freewheeling physicists who defied the imperative to “shut up and calculate” and helped to rejuvenate modern physics. For physicists, the 1970s were a time of stagnation. Jobs became scarce, and conformity was encouraged, sometimes stifling exploration of the mysteries of the physical world. Dissatisfied, underemployed, and eternally curious, an eccentric group of physicists in Berkeley, California, banded together to throw off the constraints of the physics mainstream and explore the wilder side of science. Dubbing themselves the “Fundamental Fysiks Group,” they pursued an audacious, speculative approach to physics. They studied quantum entanglement and Bell’s Theorem through the lens of Eastern mysticism and psychic mind-reading, discussing the latest research while lounging in hot tubs. Some even dabbled with LSD to enhance their creativity. Unlikely as it may seem, these iconoclasts spun modern physics in a new direction, forcing mainstream physicists to pay attention to the strange but exciting underpinnings of quantum theory. A lively, entertaining story that illuminates the relationship between creativity and scientific progress, How the Hippies Saved Physics takes us to a time when only the unlikeliest heroes could break the science world out of its rut.

Math with Bad Drawings


Book Description

A hilarious reeducation in mathematics-full of joy, jokes, and stick figures-that sheds light on the countless practical and wonderful ways that math structures and shapes our world. In Math With Bad Drawings, Ben Orlin reveals to us what math actually is; its myriad uses, its strange symbols, and the wild leaps of logic and faith that define the usually impenetrable work of the mathematician. Truth and knowledge come in multiple forms: colorful drawings, encouraging jokes, and the stories and insights of an empathetic teacher who believes that math should belong to everyone. Orlin shows us how to think like a mathematician by teaching us a brand-new game of tic-tac-toe, how to understand an economic crises by rolling a pair of dice, and the mathematical headache that ensues when attempting to build a spherical Death Star. Every discussion in the book is illustrated with Orlin's trademark "bad drawings," which convey his message and insights with perfect pitch and clarity. With 24 chapters covering topics from the electoral college to human genetics to the reasons not to trust statistics, Math with Bad Drawings is a life-changing book for the math-estranged and math-enamored alike.




Spectrum of Belief


Book Description

In the nineteenth century, scientific practice underwent a dramatic transformation from personal endeavor to business enterprise. In Spectrum of Belief, Myles Jackson explores this transformation through a sociocultural history of the rise of precision optics in Germany. He uses the career of the optician Joseph von Fraunhofer (1787-1826) to probe the relationship between science and society, and between artisans and experimental natural philosophers, during this important transition. Fraunhofer came from a long line of glassmakers. Orphaned at age eleven, the young apprentice moved in with his master, the court decorative glass cutter. At age nineteen, bored with his work and angered by his master's refusal to allow him to study optical theory, Fraunhofer took a position at the Optical Institute assisting in the manufacture of achromatic lenses. Within ten years he was producing the world's finest achromatic lenses and prisms. Housed in an old Benedictine monastery, Fraunhofer's laboratory mirrored the labor of the monks. Because of his secrecy (after his death, even those who had worked most closely with him could not achieve his success), British experimental natural philosophers were unable to reproduce his work. This secrecy, while guaranteeing his institute's monopoly, thwarted Fraunhofer's attempts to gain credibility within the scientific community, which looked down on artisanal work and its clandestine practices as an affront. The response to the ensuing rise of German optical technology sheds light on crucial social, economic, and political issues of the period, such as mechanization, patent law reform, the role of skills in both physics and society, the rise of Mechanics' Institutes, and scientific patronage. After his death, Fraunhofer's example was used in the newly united Germany to argue for the merging of scientific research and technological innovation with industrial and state support.




Advanced Quantum Mechanics (Second Edition)


Book Description

Renowned physicist and mathematician Freeman Dyson is famous for his work in quantum mechanics, nuclear weapons policy and bold visions for the future of humanity. In the 1940s, he was responsible for demonstrating the equivalence of the two formulations of quantum electrodynamics — Richard Feynman's diagrammatic path integral formulation and the variational methods developed by Julian Schwinger and Sin-Itiro Tomonoga — showing the mathematical consistency of QED.This invaluable volume comprises the legendary lectures on quantum electrodynamics first given by Dyson at Cornell University in 1951. The late theorist Edwin Thompson Jaynes once remarked, “For a generation of physicists they were the happy medium: clearer and better motivated than Feynman, and getting to the point faster than Schwinger”.This edition has been printed on the 60th anniversary of the Cornell lectures, and includes a foreword by science historian David Kaiser, as well as notes from Dyson's lectures at the Les Houches Summer School of Theoretical Physics in 1954. The Les Houches lectures, described as a supplement to the original Cornell notes, provide a more detailed look at field theory, a careful and rigorous derivation of Fermi's Golden Rule, and a masterful treatment of renormalization and Ward's Identity.Future generations of physicists are bound to read these lectures with pleasure, benefiting from the lucid style that is so characteristic of Dyson's exposition.
