David Bohm: life and times In what is perhaps Virginia Woolf's most famous novel, much of the narrative describes intentions, hopes, plans for the visit To the Lighthouse , a visit forestalled by bad weather. There follows a section ‘Time passes’ in which all is war, death, decay, desperation; only the poets thrive. Then life returns slowly and timorously; the visit is at last made, in sombre reflective mood. Between perhaps 1930 and 1952, the study of the meaning of quantum theory went through its own period of emptiness. Von Neumann had done most to cause it. Einstein could not disturb it … When interest did creep back, it was a result of the work of David Bohm. Bohm had already experienced a chequered career. He was born in the USA in 1917, and rapidly built up an exceedingly high reputation as a theoretical physicist. After initial collaboration with Robert Oppenheimer, he specialised in the physics of plasmas – gases in which, because of high temperature or low pressure, atoms are ionised , or broken up into negatively charged electrons and positively charged ions . Plasmas [118] are important in astrophysics and also in the effort to achieve controlled nuclear fusion . In nuclear fusion, small nuclei fuse together to form one large one, with the emission of energy; high temperatures are required, and so one is forced to deal with plasmas. This is also exactly the process that causes stars to radiate energy.

David Bohm A recent issue contained a review of the novel "Properties of Light," by Rebecca Goldstein (C&EN, Nov. 6, 2000, page 46). It is described as being "loosely" based on the life of physicist David Bohm. The novel contains an afterword in which it is said that Bohm (then at Princeton) published in 1952 a formulation of quantum mechanics that was outside the mainstream of modern physics at the time and was dismissed by the scientific community. As a consequence, the review states, "That rejection, in essence, ended Bohm's career. He spent most of the rest of his life in embittered obscurity." This description of David Bohm's career is a farrago of nonsense. Bohm, working from Princeton, published a standard, very useful text called "Quantum Theory" in 1951. He accepted an invitation to visit a South American university shortly afterward, but found himself barred from returning to the U.S. ...
In the early 1950s the American physicist David Bohm (1917-1992) lived through a critical moment, when he produced a new interpretation for quantum mechanics and had to flee from the United States as McCarthyism's victim.At that time he faced vicissitudes related to the Cold War and his move from Princeton to São Paulo.This article focuses on the reception among physicists of his papers on the causal interpretation, which were poorly received at the time.I describe his Brazilian exile and analyze the culture of physics surrounding the foundations of quantum mechanics.This article takes into account the strength of the Copenhagen interpretation of quantum physics among physicists, the way in which issues concerning the foundations of quantum mechanics were present in the training of physicists, the low status of these issues on research agendas, and the kind of results Bohm and collaborators were able to achieve.It also compares the reception of Bohm's ideas with that of Hugh Everett's interpretation.This article argues that the obstacles growing from the cultural context of physics at that time had a more significant influence in the reception of Bohm's ideas than did the vicissitudes related to the McCarthyist climate.WHEN DAVID BOHM and Richard Feynman concluded their physics dissertations, during the first half of the 1940s, they were among the most promising students of their generation in American physics.After the war, however, their fates were very different.Feynman reached the zenith of his scientific career in the United States.In 1951, Bohm was forced to leave the United States forever.Before that, he got a position in Princeton, carried out his research on plasma theory, and published a praised graduate
OUR EDITOR caught up with physicist David Bohm for a few days at Bailey Farm, a “think-tank” for lawyers in New York state. Autumn was crisp in the air with golden leaves and agreeable conversation as they walked together through the local woods. Bohm was in the middle of writing several books simultaneously with a number of his colleagues on the brood implications of his view of quantum physics for current ideas in psychology, sociology, and philosophy. In this wide-ranging interview, Bohm talks for the first time about his early scientific development, his relations with Robert Oppenheimer and Albert Einstein, and his idealistic struggles to actualize heightened states of being within a creative community. He also talks about imagery, stress, and the difficult evolutionary struggle in which we are currently engaged to free our minds from the negative conditioning of the past and the conceptual blind alleys of the present. David Bohm takes us on a journey into the post-modern world, a cultural step beyond relativity and quantum theory.
The day I finished my schooling I said to a friend, 'That wasn’t an education that was an accumulation'. I felt at 18, that something vital was amiss in how society and culture were looking at life, and my education had been a reflection of that. So began a tortuous journey with the usual dead ends and “car crashes”. If it’s the travelling that matters not the arriving, an important point in my endless journey to make sense of my 37 years of life came in 1983 when I first encountered David Bohm. I had just started work as a physics teacher at Brockwood Park School where Bohm regularly visited to dialogue with the founder, J. Krishnamurti, and to talk to the school about his ideas on the processes of thought.
John Stewart Bell (1928-1990), a truly deep and serious thinker, was one of the leading physi-cists of the 20th century. He became famous for his discovery that quantum mechanics impliesthat nature is nonlocal, i.e., that there are physical inuences between events that propagatefaster than light.From 1960 until his death Bell worked at CERN in Geneva on the physics of particle accel-erators, making a number of important contributions to high-energy physics and quantum eldtheory. Noteworthy was his discovery in 1969, together with Roman Jackiw, of the so-called\Bell-Jackiw-Adler anomaly (discovered independently by Stephen Adler), a mechanism ex-plaining physical e ects such as neutral pion decay (which are unexplainable on the basis of thesymmetries of the classical eld Lagrangian), in terms of an \anomalous term arising from therenormalization of quantum eld theory. Since then this mechanism has become an importantcornerstone of quantum eld theory. Another important contribution was the argument he gavein 1967 for why weak interactions should be described using a gauge theory.John Bell was one of the leading experts|perhaps the leading expert|on the foundations ofquantum mechanics. The book collecting his articles on this subject, Speakable and unspeakablein quantum mechanics, is unsurpassed for clarity and depth and it is still the best reference forwhoever wishes to learn about the eld [4].Bell strongly opposed the \Copenhagen interpretation of quantum physics, according towhich macroscopic objects, such as chairs and planets, do exist out there, but electrons andother microscopic particles do not. According to the Copenhagen view, the world is divided intotwo realms, macro and micro, \classical and \quantum, logical and contradictory|or, as Bellput it in one of his essays, into \speakable and \unspeakable. Along with Albert Einstein,Erwin Schrodinger, Louis de Broglie and !David Bohm, Bell was one of the few physicistscompelled by his conscience to reject the Copenhagen interpretation.Bell emphasized that the empirical facts of quantum physics do not at all force us to renouncerealism. There is, in fact, a realist theory (!Bohmian mechanics, also known as the de Broglie-Bohm theory) that accounts|insofar as the nonrelativistic theory is concerned|for all of thesefacts in a most elegant way. This theory describes a world in which electrons, quarks andthe like are point particles, always having positions that move in a manner dictated by thewave function. It should be taught to students, Bell insisted, as a legitimate alternative tothe prevailing orthodoxy. After GianCarlo Ghirardi, Alberto Rimini, and Tullio Weber in 1986succeeded in formulating a second kind of realist theory, Bell encouraged the further developmentof this theory as well [4, p. 201]. He thought that such a theory contained the seeds of a1
