Richard Phillips Feynman Physicist and Teacher Extraordinary
ARTICLE-IN-A-BOX Richard Phillips Feynman Physicist and Teacher Extraordinary The first three decades of the twentieth century have been among the most momentous in the history of physics. The first saw the appearance of special relativity and the birth of quantum theory; the second the creation of general relativity. And in the third, quantum mechanics proper was discovered. These developments shaped the progress of fundamental physics for the rest of the century and beyond. While the two relativity theories were largely the creation of Albert Einstein, the quantum revolution took much more time and involved about a dozen of the most creative minds of a couple of generations. Of all those who contributed to the consolidation and extension of the quantum ideas in later decades – now from the USA as much as from Europe and elsewhere – it is generally agreed that Richard Phillips Feynman was the most gifted, brilliant and intuitive genius out of many extremely gifted physicists. Here are descriptions of him by leading physicists of his own, and older as well as younger generations: “He is a second Dirac, only this time more human.” – Eugene Wigner …Feynman was not an ordinary genius but a magician, that is one “who does things that nobody else could ever do and that seem completely unexpected.” – Hans Bethe “… an honest man, the outstanding intuitionist of our age and a prime example of what may lie in store for anyone who dares to follow the beat of a different drum..” – Julian Schwinger “… the most original mind of his generation.” – Freeman Dyson Richard Feynman was born on 11 May 1918 in Far Rockaway near New York to Jewish parents Lucille Phillips and Melville Feynman. -

Einstein and Hilbert: the Creation of General Relativity
EINSTEIN AND HILBERT: THE CREATION OF GENERAL RELATIVITY ∗ Ivan T. Todorov Institut f¨ur Theoretische Physik, Universit¨at G¨ottingen, Friedrich-Hund-Platz 1 D-37077 G¨ottingen, Germany; e-mail: [email protected] and Institute for Nuclear Research and Nuclear Energy, Bulgarian Academy of Sciences Tsarigradsko Chaussee 72, BG-1784 Sofia, Bulgaria;∗∗e-mail: [email protected] ABSTRACT It took eight years after Einstein announced the basic physical ideas behind the relativistic gravity theory before the proper mathematical formulation of general relativity was mastered. The efforts of the greatest physicist and of the greatest mathematician of the time were involved and reached a breathtaking concentration during the last month of the work. Recent controversy, raised by a much publicized 1997 reading of Hilbert’s proof- sheets of his article of November 1915, is also discussed. arXiv:physics/0504179v1 [physics.hist-ph] 25 Apr 2005 ∗ Expanded version of a Colloquium lecture held at the International Centre for Theoretical Physics, Trieste, 9 December 1992 and (updated) at the International University Bremen, 15 March 2005. ∗∗ Permanent address. Introduction Since the supergravity fashion and especially since the birth of superstrings a new science emerged which may be called “high energy mathematical physics”. One fad changes the other each going further away from accessible experiments and into mathe- matical models, ending up, at best, with the solution of an interesting problem in pure mathematics. The realization of the grand original design seems to be, decades later, nowhere in sight. For quite some time, though, the temptation for mathematical physi- cists (including leading mathematicians) was hard to resist. -
More Eugene Wigner Stories; Response to a Feynman Claim (As Published in the Oak Ridger’S Historically Speaking Column on August 29, 2016)
More Eugene Wigner stories; Response to a Feynman claim (As published in The Oak Ridger’s Historically Speaking column on August 29, 2016) Carolyn Krause has collected a couple more stories about Eugene Wigner, plus a response by Y- 12 to allegations by Richard Feynman in a book that included a story on his experience at Y-12 during World War II. … Mary Ann Davidson, widow of Jack Davidson, a longtime member of the Oak Ridge National Laboratory’s Instrumentation and Controls Division, told me about Jack’s encounter with Wigner one day. Once Eugene Wigner had trouble opening his briefcase while visiting ORNL. He was referred to Jack Davidson in the old Instrumentation and Controls Division. Jack managed to open it for him. As was his custom, Wigner asked Jack about his research. Jack, who later won an R&D-100 award, said he was building a camera that will imitate a fly’s eye; in other words, it will capture light coming from a variety of directions. The topic of television and TV cameras came up. Wigner said he wondered how TV works. So Davidson explained the concept to him. Charles Jones told me this story about Eugene Wigner when he visited ORNL in the 1980s. Jones, who was technical director of the Holifield Heavy Ion Research Facility, said he invited Wigner to accompany him to the top of the HHIRF tower, and Wigner happily accepted the offer. At the top Wigner looked down at all the ORNL buildings, most of which had been constructed after he was the lab’s research director in 1946-47. -

A Mathematician's Journey to the Edge of the Universe "The only true wisdom is in knowing you know nothing." ― Socrates Manjunath.R #16/1, 8th Main Road, Shivanagar, Rajajinagar, Bangalore560010, Karnataka, India *Corresponding Author Email: [email protected] *Website: http://www.myw3schools.com/ A Mathematician's Journey to the Edge of the Universe What’s the Ultimate Question? Since the dawn of the history of science from Copernicus (who took the details of Ptolemy, and found a way to look at the same construction from a slightly different perspective and discover that the Earth is not the center of the universe) and Galileo to the present, we (a hoard of talking monkeys who's consciousness is from a collection of connected neurons − hammering away on typewriters and by pure chance eventually ranging the values for the (fundamental) numbers that would allow the development of any form of intelligent life) have gazed at the stars and attempted to chart the heavens and still discovering the fundamental laws of nature often get asked: What is Dark Matter? ... What is Dark Energy? ... What Came Before the Big Bang? ... What's Inside a Black Hole? ... Will the universe continue expanding? Will it just stop or even begin to contract? Are We Alone? Beginning at Stonehenge and ending with the current crisis in String Theory, the story of this eternal question to uncover the mysteries of the universe describes a narrative that includes some of the greatest discoveries of all time and leading personalities, including Aristotle, Johannes Kepler, and Isaac Newton, and the rise to the modern era of Einstein, Eddington, and Hawking. -
Julian Schwinger (1918-1994)
Julian Schwinger (1918-1994) K. A. Milton Homer L. Dodge Department of Physics and Astronomy, University of Oklahoma, Norman, OK 73019 June 15, 2006 Julian Schwinger’s influence on Twentieth Century science is profound and pervasive. Of course, he is most famous for his renormalization theory of quantum electrodynamics, for which he shared the Nobel Prize with Richard Feynman and Sin-itiro Tomonaga. But although this triumph was undoubt- edly his most heroic accomplishment, his legacy lives on chiefly through sub- tle and elegant work in classical electrodynamics, quantum variational princi- ples, proper-time methods, quantum anomalies, dynamical mass generation, partial symmetry, and more. Starting as just a boy, he rapidly became the pre-eminent nuclear physicist in the late 1930s, led the theoretical develop- ment of radar technology at MIT during World War II, and then, soon after the war, conquered quantum electrodynamics, and became the leading quan- tum field theorist for two decades, before taking a more iconoclastic route during his last quarter century. Given his commanding stature in theoretical physics for decades it may seem puzzling why he is relatively unknown now to the educated public, even to many younger physicists, while Feynman is a cult figure with his photograph needing no more introduction than Einstein’s. This relative ob- scurity is even more remarkable, in view of the enormous number of eminent physicists, as well as other leaders in science and industry, who received their Ph.D.’s under Schwinger’s direction, while Feynman had but few. In part, the answer lies in Schwinger’s retiring nature and reserved demeanor. -
LUIS ALVAREZ and the PYRAMID BURIAL CHAMBERS, the JFK ASSASSINATION, and the END of the DINOSAURS Charles G
SCIENTIST AS DETECTIVE: LUIS ALVAREZ AND THE PYRAMID BURIAL CHAMBERS, THE JFK ASSASSINATION, AND THE END OF THE DINOSAURS Charles G. Wohl Lawrence Berkeley National Laboratory, Berkeley, CA 94720 Luis Alvarez (1911{1988) was one of the most brilliant and productive experimental physicists of the twentieth century. His investigations of three mysteries, all of them outside his normal areas of research, show the wonders that a far-ranging imagination working with an immense store of knowledge can accomplish. The 1968 Nobel Prize in Physics, awarded to Luis W. Alvarez: • \For his decisive contributions to elementary particle physics, in particular the discovery of a large number of resonant states, made possible through his devel- opment of the technique of using hydrogen bubble chambers and data analysis." Richard Feynman, considering whether or not to do the O-ring-in-ice-water demonstration• in the Challenger disaster hearings: \I think, `I could do this tomorrow while we're all sitting around, listening to this [Richard] Cook crap we heard today. We always get ice water in those meetings; that's something I could do to save time.' \Then I think, `No, that would be gauche.' \But then I think of Luis Alvarez, the physicist. He's a guy I admire for his gutsiness and sense of humor, and I think, `If Alvarez was on this commission, he would do it, and that's good enough for me.' "1 1.

Something Is Rotten in the State of QED
February 2020 Something is rotten in the state of QED Oliver Consa Independent Researcher, Barcelona, Spain Email: [email protected] Quantum electrodynamics (QED) is considered the most accurate theory in the his- tory of science. However, this precision is based on a single experimental value: the anomalous magnetic moment of the electron (g-factor). An examination of QED history reveals that this value was obtained using illegitimate mathematical traps, manipula- tions and tricks. These traps included the fraud of Kroll & Karplus, who acknowledged that they lied in their presentation of the most relevant calculation in QED history. As we will demonstrate in this paper, the Kroll & Karplus scandal was not a unique event. Instead, the scandal represented the fraudulent manner in which physics has been conducted from the creation of QED through today. 1 Introduction truth the hypotheses of the former members of the Manhat- tan Project were rewarded with positions of responsibility in After the end of World War II, American physicists organized research centers, while those who criticized their work were a series of three transcendent conferences for the separated and ostracized. The devil’s seed had been planted development of modern physics: Shelter Island (1947), in the scientific community, and its inevitable consequences Pocono (1948) and Oldstone (1949). These conferences were would soon grow and flourish. intended to be a continuation of the mythical Solvay confer- ences. But, after World War II, the world had changed. 2 Shelter Island (1947) The launch of the atomic bombs in Hiroshima and 2.1 The problem of infinities Nagasaki (1945), followed by the immediate surrender of Japan, made the Manhattan Project scientists true war heroes.
