Bohm in American Prometheus

 Bohm in American Prometheus

Weinberg quickly became a devoted member of Oppenheimer’s inner circle. “He knew that I adored him,” Weinberg said, “as we all did.” Philip Morrison, Giovanni Rossi Lomanitz, David Bohm and Max Friedman were some of the other graduate students who regarded Oppenheimer as their mentor and role model during these years. These were unconventional young men who, in the words of Morrison, prided themselves on being “self-conscious and daring intellectuals.” All of them were studying theoretical physics. And all of them were active in one or another Popular Front cause. Some, like Philip Morrison and David Bohm, have acknowledged that they joined the Communist Party. Others were merely on the fringe. Joe Weinberg was probably in the Party for at least a brief time.


Page 171


“We were all close to communism at the time,’ Bohm recalled. Actually, until 1940-41, Bohm didn’t have much sympathy for the Communist Party. But then, with the collapse of France, it seemed to him that no one but the communists had the will to resist the Nazis. Indeed, many Europeans


Page 172


appeared to prefer the Nazis to the Russians. “And I felt,’ Bohm said, “that there was such a trend in America too. I thought the Nazis were a total threat to civilization. . . . It seemed that the Russians were the only ones that were really fighting them. Then I began to listen to what they said more sympathetically.”


Page 172


In November 1942, just as the Russians opened up an offensive to push the Nazis back from the outskirts of Stalingrad, Bohm began attending regular meetings at a Berkeley chapter of the Communist Party. Typically, fifteen people might show up. After a while, Bohm found the meetings “interminable,” and decided that the group’s various plans to “stir up things on the campus” didn’t amount to much. “I had the feeling that they were really rather ineffective.” Gradually, Bohm just stopped attending. But he remained a passionate and enthusiastic intellectual Marxist, reading Marxist texts together with his closest friends at the time, Weinberg, Lomanitz and Bernard Peters.

David Hawkins came to Berkeley in 1936 to study philosophy. Almost immediately, he fell in with a number of Oppenheimer’s students, including Phil Morrison, David Bohm and Joe Weinberg. Hawkins encountered Oppenheimer one day at a meeting of the Teachers’ Union; they were discussing the plight of underpaid teaching assistants and Hawkins recalled being struck by Oppenheimer’s eloquence and sympathetic demeanor: “He was very persuasive, very cogent, elegant in language and able to listen to what other people said and incorporate it in what he would say. I had the

OPPENHEIMER BACKED OFF from the union in the autumn of 1941, but the notion of organizing the scientists in the Rad Lab did not die. A little more than a year later, in early 1943, Rossi Lomanitz, Irving David Fox, David Bohm, Bernard Peters and Max Friedman, all Oppenheimer students, did join the union (FAECT Local 25). The usual motivations for forming a union were conspicuously absent. Lomanitz, for one, was making $150 a month at the Rad Lab—more than double his previous salary. No one had

By the autumn of 1942, it was more or less an open secret around Berkeley that Oppenheimer and his students were exploring the feasibility of a powerful new weapon associated with the atom. He had sometimes talked about his work, even to casual acquaintances. John McTernan, an attorney for the National Labor Relations Board, and a friend of Jean Tatlock’s, ran into Oppenheimer one evening at a party and vividly recalled the encounter: “He talked very fast, trying to explain his work on this explosive device. I didn’t understand a word he was saying. .. . And then, the next time I saw him he made it clear that he was no longer free to talk about it.’ Almost anyone who had friends in the physics department might have heard speculation about such work. David Bohm thought that “many people all around knew what was going on at Berkeley... . It didn’t take much to piece it together.”


Page 187


A young graduate student in the psychology department, Betty Goldstein, arrived on campus fresh from Smith in the autumn of 1942 and befriended several of Oppenheimer’s graduate students. The future Betty Friedan began dating David Bohm, who was writing his doctoral dissertation in physics under Oppie’s supervision. Bohm—who decades later became a world-famous physicist and philosopher of science—fell in love with Betty, and introduced her to his friends, Rossi Lomanitz, Joe Weinberg and Max Friedman. They all socialized on weekends and sometimes saw each other in what Friedan characterized as “various radical study groups.”

to Steve Nelson. Initially, Pash’s investigation focused on Lomanitz, merely because Pash had information that Lomanitz was a Communist Party member. A tail was put on Lomanitz, and one day in June 1943 he was observed standing just outside U.C. Berkeley’s Sather Gate with several friends. They were posing, with their arms draped over each other’s shoulders, for a photographer who routinely sold his services to students on campus. After the photo was taken and Lomanitz and his friends walked away, a government agent walked up to the photographer and bought the negative. Lomanitz’ friends were quickly identified as Joe Weinberg, David Bohm and Max Friedman—all of them Oppie’s students. From that moment on, these young men were marked as subversives.


Page 192


Lieutenant Colonel Pash testified that his investigators “determined in the first place that these four men I mentioned were very frequently together.” Without divulging “investigative techniques or operational procedures,” Pash explained that “we had an unidentified man and we had this photograph. As a result of our study we determined and were sure that Joe was Joseph Weinberg.” He also claimed that he had “sufficient information” to name both Weinberg and Bohm as Communist Party members.


Page 192


Pash was convinced that he had stumbled upon a sophisticated ring of wily Soviet agents, and he felt that any means necessary should be used to break the suspects. In July 1943, the FBI field office in San Francisco reported that Pash wanted to kidnap Lomanitz, Weinberg, Bohm and Friedman, take them out to sea in a boat and interrogate them “after the Russian manner.” The FBI noted that any information gathered in such a fashion could not be used in court, “but apparently Pash did not intend to have anyone available for prosecution after questioning.” This was too much for the FBI: “Pressure was brought to bear to discourage this particular activity.”


Page 193


IN THE SPRING OF 1943, just as David Bohm was trying to write up his thesis research on the collisions of protons and deuterons, he was suddenly told that such work was classified. Since he lacked the necessary security clearance, his own notes on scattering calculations were seized and he was informed that he was barred from writing up his own research. He appealed to Oppenheimer, who then wrote a letter certifying that his student had nevertheless met the requirements for a thesis. On this basis, Bohm was awarded his Ph.D. by Berkeley in June 1943. Although Oppenheimer personally requested the transfer of Bohm to Los Alamos, Army security officers flatly refused to give him clearance. Instead, a disbelieving Oppenheimer was told that because Bohm still had relatives in Germany, he couldn’t be cleared for special work. This was a lie; in fact Bohm was banned from Los Alamos because of his association with Weinberg. He spent the war years working in the Radiation Lab, where he studied the behavior of plasmas.


Page 193


Although barred from working on the Manhattan Project, Bohm was able to continue his work as a physicist. Lomanitz and several others were not so fortunate. Shortly after Ernest Lawrence appointed him to serve as the liaison between the Rad Lab and the Manhattan Project’s plant at Oak Ridge, Lomanitz received a draft notice from the Army. Both Lawrence and Oppenheimer interceded for him, but to no avail. Lomanitz spent the remainder of the war years in various stateside Army camps.

of Jean’s phone but had also proposed to interrogate Weinberg, Lomanitz, Bohm and Friedman “in the Russian manner” and then dispose of their bodies at sea.

Joe Weinberg, Rossi Lomanitz, David Bohm and Max Friedman were some of Oppie’s acolytes at Berkeley. “They copied his gestures, his mannerisms, his intonations,” recalled Bob Serber.


Page 373


Pais soon had a chance to observe Oppenheimer in action. For three days in June 1947, twenty-three of the country’s leading theoretical physicists gathered at the Ram’s Head Inn, an exclusive resort on Shelter Island, at the eastern tip of Long Island. Oppenheimer had taken the lead in organizing the conference. Among others, he brought Hans Bethe, I. I. Rabi, Richard Feynman, Victor Weisskopf, Edward Teller, George Uhlenbeck, Julian Schwinger, David Bohm, Robert Marshak, Willis Lamb and Hendrik Kramers to discuss “The Foundations of Quantum Mechanics.” With the end of the war, theoretical physicists were finally able to shift their attention back to fundamental issues. One of Oppenheimer’s doctoral students, Willis Lamb, gave the first of the conference’s many remarkable presentations, outlining what would soon become known as the “Lamb shift,” which in turn became a key step to a new theory of quantum electrodynamics. (Lamb would win a Nobel Prize in 1955 for his work on this topic.) Similarly, Rabi gave a groundbreaking talk on nuclear magnetic resonance.


Page 374


Not everyone applauded Oppenheimer’s performance. David Bohm recalled thinking that Oppie was talking too much. “He was very fluent with his words,” Bohm said, “but there wasn’t much behind what he was saying to back up that much talking.” Bohm thought his mentor had begun to lose his insightfulness, perhaps simply because he hadn’t been doing anything of any substance in physics for many years. 

“He [Oppenheimer] didn’t sympathize with what I was doing in physics,’ Bohm recalled. “I wanted to question fundamentals, and he felt that one should work on using the present theory, exploiting it and trying to work out its consequences.” Earlier in their relationship, Bohm had had tremendous regard for Oppenheimer. But over time he found himself agreeing with another friend who had worked with Oppenheimer, Milton Plesset, who expressed the view that Oppie was “not capable of genuine originality, but that he is very good at comprehending other people’s ideas and seeing their implications.”

OPPENHEIMER MaAy have hoped to inoculate himself against congressional investigators, but in the spring of 1949 HUAC launched a major investigation of atomic spying at Berkeley’s Rad Lab. Not only Frank but Robert himself was a potential target. Four of Oppenheimer’s former students— David Bohm, Rossi Lomanitz, Max Friedman and Joseph Weinberg—were served with subpoenas requiring them to testify. HUAC’s investigators knew that Weinberg had been overheard on a wiretap talking to Steve Nelson in 1943 about the atomic bomb. But while this evidence appeared to implicate Weinberg in atomic spying, HUAC’s counsel knew that a warrantless wiretap would not stand up in court. On April 26, 1949, HUAC brought Weinberg face-to-face with Steve Nelson. He flatly denied having ever met


Page 394


Nelson. HUAC’s lawyers knew Weinberg had perjured himself—but proving it was going to be difficult. They hoped to build their case with testimony from Bohm, Friedman and Lomanitz.


Page 394


Bohm was not sure whether he should testify, and if so, whether he should be willing to testify about his friends. Einstein urged him to refuse to testify, even though he might have to go to jail. “You may have to sit for a while,” the scientist told him. Bohm didn’t want to take the Fifth Amendment; he reasoned that being a member of the Communist Party was not illegal, and therefore there was nothing he could incriminate himself about. His instinct was to agree to testify about his own political activities but refuse to testify about others. Aware that Lomanitz had received a similar subpoena, Bohm contacted his old friend, who was teaching in Nashville at the time. Lomanitz had had a rough time since the war; each time he found a decent job, the FBI would inform his employer that Lomanitz was a communist and he would be fired. His future seemed particularly bleak, but he found the wherewithal to visit Bohm in Princeton.


Page 394


Soon after his arrival, the two old friends were walking on Nassau Street when Oppenheimer emerged from a barbershop. Robert hadn’t seen Lomanitz for years, but they had kept in touch. In the autumn of 1945, he had written Lomanitz. “Dear Rossi: I was glad to get your long, but very melancholy letter. When you are back in the States and free to do so please come and see me... . It is a hard time, and especially hard for you, but hold on—it won’t last forever. With all warm good wishes, Opje.” Now, after exchanging pleasantries with Oppie, Bohm and Lomanitz explained their predicament. According to Lomanitz, Oppenheimer became agitated and suddenly exclaimed, “Oh, my God, all is lost. There is an FBI man on the Un-American Activities Committee.” Lomanitz thought this “paranoiac.”


Page 394


Oppenheimer later characterized this encounter with his former students as a brief two-minute conversation. He said he had merely advised them to “tell the truth,’ and they had responded, “We won’t lie.” In the event, Bohm testified before HUAC in May and again in June 1949. On advice of his counsel, the legendary civil liberties lawyer Clifford Durr, he refused to cooperate, citing both the First and Fifth amendments. For the time being, Princeton University, where he was then teaching, issued a statement supporting Bohm.


Page 399


Peters had it easy compared to Bohm and Lomanitz. More than a year later, they were both indicted for contempt of Congress; after Bohm was arrested on December 4, 1950 (and released on $1,500 bail), Princeton suspended him from all his teaching duties and even barred him from setting foot on the campus. Six months later, he was tried and acquitted. Even so, Princeton decided not to renew Bohm’s teaching contract when it expired that June.


Page 400


While there was little Oppenheimer could have done to protect his former students, he sometimes behaved as if he was truly frightened of any association with them. Their company represented a link to his political past and therefore a threat to his political future. 

He was clearly scared. After Bohm lost his job with Princeton, Einstein suggested that he be brought to the Institute for Advanced Study to work as his assistant. The great man was still interested in revising quantum theory, and he was heard to say that “if anyone can do it, then it will be Bohm.” 

But Oppenheimer vetoed the idea; Bohm would be a political liability to the Institute. By one account, he also reportedly instructed Eleanor Leary to keep Bohm away. Leary was subsequently heard telling the Institute’s staff, “David Bohm is not to see Dr. Oppenheimer. He is not to see him.”

오펜하이머는 이전 학생들을 보호하기 위해 할 수 있는 일이 거의 없었지만 때로는 그들과의 관계를 정말로 두려워하는 것처럼 행동했습니다. 그들의 회사는 그의 정치적 과거와 연결되어 그의 정치적 미래에 대한 위협을 나타냈습니다. 그는 분명히 겁을 먹었습니다. 봄이 프린스턴에서 직장을 잃은 후, 아인슈타인은 그에게 고등연구소에 가서 조교로 일할 것을 제안했습니다. 그 위대한 사람은 여전히 양자 이론을 수정하는 데 관심이 있었고, “누구든지 할 수 있다면 그것은 봄이 될 것”이라는 말을 들었습니다. 그러나 오펜하이머는 그 아이디어를 거부했습니다. Bohm은 연구소에 대한 정치적 책임이 될 것입니다. 한 설명에 따르면 그는 Eleanor Leary에게 Bohm을 멀리하라고 지시한 것으로 알려졌습니다. 나중에 Leary는 연구소 직원에게 다음과 같이 말하는 것을 들었습니다. “David Bohm은 Oppenheimer 박사를 만날 수 없습니다. 그 사람은 만나면 안 돼.”

Page 400


As a matter of expediency, Oppenheimer had every reason to distance himself from Bohm. On the other hand, when Bohm heard of a teaching opportunity in Brazil, Oppenheimer wrote him a strong letter of recommendation. Bohm spent the rest of his career abroad, first in Brazil, then in Israel and finally in England. He had once deeply admired Oppenheimer, and though over the years those feelings had turned to ambivalence, he never held Oppie responsible for his banishment from America. “I think he acted fairly to me as far as he was able to,” Bohm said.

편의상 오펜하이머는 봄과 거리를 둘 충분한 이유가 있었습니다. 한편, Bohm이 브라질에서 가르칠 기회가 있다는 소식을 들었을 때 Oppenheimer는 그에게 강력한 추천서를 썼습니다. Bohm은 남은 경력을 처음에는 브라질, 그다음에는 이스라엘, 마지막으로 영국에서 해외에서 보냈습니다. 그는 한때 오펜하이머를 깊이 존경했으며, 수년이 지나면서 그러한 감정은 양가감정으로 바뀌었지만, 결코 오피에게 미국에서 추방된 책임을 묻지 않았습니다. “나는 그가 할 수 있는 한 나에게 공정하게 행동했다고 생각합니다.”라고 Bohm은 말했습니다.

Page 400


Bohm knew Oppenheimer was under a great deal of strain. Shortly after the news broke about his HUAC testimony against Peters, Bohm had a candid conversation with Oppie. He asked why he had said such things about their friend. “He told me,’ Bohm recalled, “that his nerve just gave way at that moment. That somehow the thing was too much for him.... I can’t remember his words, but that’s what he meant. He has this tendency when things get too much, he sometimes does irrational things. He said he couldn’t understand why he did it.” Of course, it had happened before—in his interview with Pash in 1943 and his meeting with Truman in 1945—and it would happen again during his security hearing in 1954. But, as Bernard Peters observed to Weisskopf, “He [Oppenheimer] was obviously scared to tears of the hearings, but this is hardly an explanation. . . . I found it a rather sad experience to see a man whom I regarded very highly in such a state of moral despair.”


Page 439


claimed that after being shown photographs by the FBI, they could place David Bohm, George Eltenton and Joseph Weinberg at the same meeting. Sylvia named Weinberg as “Scientist X,” the individual labeled by the House Un-American Activities Committee as someone who gave atomic bomb secrets to a communist spy during the war. The California papers played these allegations as a “bombshell.” Paul Crouch was described as a ‘West Coast Whittaker Chambers,’ a reference to the Time magazine editor and former communist whose testimony had led, on January 21, 1950, to the perjury conviction of Alger Hiss.

Gray spent the morning reading aloud the AEC’s letter of “indictment” and Oppenheimer’s reply. Over the next three and a half weeks, Gray repeatedly insisted that the proceedings were an “inquiry,” not a trial. But no one could listen to the AEC’s letter of charges without thinking that Robert Oppenheimer was on trial. His alleged crimes included joining numerous Communist Party front organizations; being “intimately associated” with a known communist, Dr. Jean Tatlock; associating with such other “known” communists as Dr. Thomas Addis, Kenneth May, Steve Nelson, and Isaac Folkoff; being responsible for the employment in the atom bomb project of such known communists as Joseph W. Weinberg, David Bohm, Rossi Lomanitz (all former students of Oppenheimer’s) and David

The clearest and most convincing explanation of why Oppenheimer presented Pash with such an elaborately confused representation of his kitchen conversation with Chevalier was offered by Oppenheimer himself the day before his security hearing was concluded. His explanation not only conforms with the most compelling known facts, but it also conforms with Oppenheimer’s character—especially, as he had confessed to David Bohm five years earlier, “his tendency when things get too much” to say “irrational things.” Responding to Chairman Gray’s query whether he might have been telling the truth in 1943 to Pash and Lansdale, and was, in fact, fabricating today about the Chevalier incident, Oppenheimer replied:

THE NEXT DAY, Friday, April 16, Robb resumed his cross-examination of Oppenheimer. He grilled him about his relationships with the Serbers, David Bohm and Joe Weinberg, and late in the day he got around to asking the physicist about his opposition to the development of the hydrogen bomb. After nearly five full days of intense interrogation, Oppenheimer must have been physically and mentally exhausted. But on this day—his last in the witness chair—he nevertheless mustered his razor-sharp wit. Wary from experience at being ambushed, and crystal clear about the issue, he was more adept at parrying Robb’s questions.


Page 584


In early December 1966, Oppenheimer heard from his former student, David Bohm, who had spent most of his career in Brazil and later, England. Bohm wrote to say that he had seen the Kipphardt play and a television program on Los Alamos in which Oppenheimer had been interviewed. “I was rather disturbed,’ Bohm wrote, “especially by a statement you made, indicating a feeling of guilt on your part. I feel it to be a waste of the life that is left to you for you to be caught up in such guilt feelings.” 

He then reminded Oppenheimer of a play by Jean-Paul Sartre “in which the hero is finally freed of guilt by recognizing responsibility. As I understand it, one feels guilty for past actions, because they grew out of what one was and still is.” Bohm believed that mere guilt feelings are meaningless. “I can understand that your dilemma was a peculiarly difficult one. Only you can assess the way in which you were responsible for what happened. . . .”

1966년 12월 초, 오펜하이머는 자신의 경력 대부분을 브라질과 이후 영국에서 보낸 그의 전 제자 데이비드 봄(David Bohm)으로부터 소식을 들었습니다. Bohm은 Kipphardt 연극과 Oppenheimer가 인터뷰한 Los Alamos의 TV 프로그램을 보았다고 썼습니다. Bohm은 이렇게 썼습니다. “특히 당신이 죄책감을 느꼈다는 진술을 했을 때 오히려 마음이 불안했습니다. 그런 죄책감에 사로잡혀 있는 것은 당신에게 남겨진 인생의 낭비라고 생각합니다.” 그런 다음 그는 오펜하이머에게 Jean-Paul Sartre의 연극을 상기시켰습니다. “여기에서 영웅은 책임을 인식함으로써 마침내 죄책감에서 해방됩니다. 내가 이해하는 바에 따르면, 사람은 과거의 행동에 대해 죄책감을 느낍니다. 왜냐하면 과거의 행동이 과거와 현재의 상태에서 성장했기 때문입니다.” Bohm은 단순한 죄책감은 의미가 없다고 믿었습니다. “나는 당신의 딜레마가 유난히 어려운 문제였다는 것을 이해합니다. 오직 당신만이 일어난 일에 대해 당신이 책임을 지는 방식을 평가할 수 있습니다. . . .”

David Joseph Bohm FRS[1] (/bm/; 20 December 1917 – 27 October 1992) was an American–Brazilian–British scientist who has been described as one of the most significant theoretical physicists of the 20th century[2] and who contributed unorthodox ideas to quantum theoryneuropsychology and the philosophy of mind. Among his many contributions to physics is his causal and deterministic interpretation of quantum theory known as De Broglie–Bohm theory.

Bohm advanced the view that quantum physics meant that the old Cartesian model of reality—that there are two kinds of substance, the mental and the physical, that somehow interact—was too limited. To complement it, he developed a mathematical and physical theory of "implicate" and "explicate" order.[3] 

He also believed that the brain, at the cellular level, works according to the mathematics of some quantum effects, and postulated that thought is distributed and non-localised just as quantum entities are.[4][failed verification] Bohm's main concern was with understanding the nature of reality in general and of consciousness in particular as a coherent whole, which according to Bohm is never static or complete.[5]

Bohm warned of the dangers of rampant reason and technology, advocating instead the need for genuine supportive dialogue, which he claimed could broaden and unify conflicting and troublesome divisions in the social world. In this, his epistemology mirrored his ontology.[6]

Born in the United States, Bohm obtained his Ph.D. under J. Robert Oppenheimer at the University of California, Berkeley

Due to his Communist affiliations, he was the subject of a federal government investigation in 1949, prompting him to leave the U.S. He pursued his career in several countries, becoming first a Brazilian and then a British citizen. He abandoned Marxism in the wake of the Hungarian Uprising in 1956.[7][8]

Youth and college[edit]

Bohm was born in Wilkes-BarrePennsylvania, to a Hungarian Jewish immigrant father, Samuel Bohm,[9] and a Lithuanian Jewish mother. He was raised mainly by his father, a furniture-store owner and assistant of the local rabbi. Despite being raised in a Jewish family, he became an agnostic in his teenage years.[10] Bohm attended Pennsylvania State College (now Pennsylvania State University), graduating in 1939, and then the California Institute of Technology, for one year. He then transferred to the theoretical physics group directed by Robert Oppenheimer at the University of California, Berkeley Radiation Laboratory, where he obtained his doctorate.

Bohm lived in the same neighborhood as some of Oppenheimer's other graduate students (Giovanni Rossi LomanitzJoseph Weinberg, and Max Friedman) and with them became increasingly involved in radical politics. He was active in communist and communist-backed organizations, including the Young Communist League, the Campus Committee to Fight Conscription, and the Committee for Peace Mobilization. During his time at the Radiation Laboratory, Bohm was in a relationship with the future Betty Friedan and also helped to organize a local chapter of the Federation of Architects, Engineers, Chemists and Technicians, a small labor union affiliated to the Congress of Industrial Organizations (CIO).[11]

Work and doctorate[edit]

Manhattan Project contributions[edit]

During World War II, the Manhattan Project mobilized much of Berkeley's physics research in the effort to produce the first atomic bomb. Though Oppenheimer had asked Bohm to work with him at Los Alamos (the top-secret laboratory established in 1942 to design the atom bomb), the project's director, Brigadier General Leslie Groves, would not approve Bohm's security clearance after seeing evidence of his politics and his close friendship with Weinberg, who had been suspected of espionage.

During the war, Bohm remained at Berkeley, where he taught physics and conducted research in plasma, the synchrotron and the synchrocyclotron. He completed his PhD in 1943 by an unusual circumstance. 

According to biographer F. David Peat,[12] "The scattering calculations (of collisions of protons and deuterons) that he had completed proved useful to the Manhattan Project and were immediately classified. Without security clearance, Bohm was denied access to his own work; not only would he be barred from defending his thesis, he was not even allowed to write his own thesis in the first place!" To satisfy the University, Oppenheimer certified that Bohm had successfully completed the research. Bohm later performed theoretical calculations for the Calutrons at the Y-12 facility in Oak Ridge, Tennessee. These calculations were used for the electromagnetic enrichment of uranium for the bomb dropped on Hiroshima in 1945.

McCarthyism and leaving the United States[edit]

After the war, Bohm became an assistant professor at Princeton University. He also worked closely with Albert Einstein at the nearby Institute for Advanced Study. In May 1949, the House Un-American Activities Committee called upon Bohm to testify because of his previous ties to unionism and suspected communists. Bohm invoked his Fifth Amendment right to refuse to testify, and he refused to give evidence against his colleagues.

In 1950, Bohm was arrested for refusing to answer the committee's questions. He was acquitted in May 1951, but Princeton had already suspended him. After his acquittal, Bohm's colleagues sought to have him reinstated at Princeton, but Princeton President Harold W. Dodds[13] decided not to renew Bohm's contract. Although Einstein considered appointing him as his research assistant at the Institute, Oppenheimer (who had served as the Institute's president since 1947) "opposed the idea and [...] advised his former student to leave the country".[14] His request to go to the University of Manchester received Einstein's support but was unsuccessful.[15] Bohm then left for Brazil to assume a professorship of physics at the University of São Paulo, at Jayme Tiomno's invitation and on the recommendation of both Einstein and Oppenheimer.

Quantum theory and Bohm diffusion[edit]

The Bohmian trajectories for an electron going through the two-slit experiment. A similar pattern was also observed for single photons.[16]

During his early period, Bohm made a number of significant contributions to physics, particularly quantum mechanics and relativity theory. As a postgraduate at Berkeley, he developed a theory of plasmas, discovering the electron phenomenon known as Bohm diffusion.[17] His first book, Quantum Theory, published in 1951, was well received by Einstein, among others. But Bohm became dissatisfied with the orthodox interpretation of quantum theory he wrote about in that book. Starting from the realization that the WKB approximation of quantum mechanics leads to deterministic equations and convinced that a mere approximation could not turn a probabilistic theory into a deterministic theory, he doubted the inevitability of the conventional approach to quantum mechanics.[18]

Bohm's aim was not to set out a deterministic, mechanical viewpoint but to show that it was possible to attribute properties to an underlying reality, in contrast to the conventional approach.[19] He began to develop his own interpretation (the De Broglie–Bohm theory, also called the pilot wave theory), the predictions of which agreed perfectly with the non-deterministic quantum theory. He initially called his approach a hidden variable theory, but he later called it ontological theory, reflecting his view that a stochastic process underlying the phenomena described by his theory might one day be found. Bohm and his colleague Basil Hiley later stated that they had found their own choice of terms of an "interpretation in terms of hidden variables" to be too restrictive, especially since their variables, position, and momentum "are not actually hidden".[20]

Bohm's work and the EPR argument became the major factor motivating John Stewart Bell's inequality, which rules out local hidden variable theories; the full consequences of Bell's work are still being investigated.

Brazil[edit]

After Bohm's arrival in Brazil on 10 October 1951, the US Consul in São Paulo confiscated his passport, informing him he could retrieve it only to return to his country, which reportedly frightened Bohm[21] and significantly lowered his spirits, as he had hoped to travel to Europe. He applied for and received Brazilian citizenship, but by law, had to give up his US citizenship; he was able to reclaim it only decades later, in 1986, after pursuing a lawsuit.[22]

At the University of São Paulo, Bohm worked on the causal theory that became the subject of his publications in 1952. Jean-Pierre Vigier traveled to São Paulo, where he worked with Bohm for three months; Ralph Schiller, student of cosmologist Peter Bergmann, was his assistant for two years; he worked with Tiomno and Walther Schützer; and Mario Bunge stayed to work with him for one year. He was in contact with Brazilian physicists Mário SchenbergJean MeyerLeite Lopes, and had discussions on occasion with visitors to Brazil, including Richard FeynmanIsidor RabiLéon RosenfeldCarl Friedrich von WeizsäckerHerbert L. AndersonDonald KerstMarcos Moshinsky, Alejandro Medina, and the former assistant to HeisenbergGuido Beck, who encouraged him in his work and helped him to obtain funding. The Brazilian CNPq explicitly supported his work on the causal theory and funded several researchers around Bohm. His work with Vigier was the beginning of a long-standing cooperation between the two and Louis De Broglie, in particular, on connections to the hydrodynamics model proposed by Madelung.[23] Yet the causal theory met much resistance and skepticism, with many physicists holding the Copenhagen interpretation to be the only viable approach to quantum mechanics.[22]

From 1951 to 1953, Bohm and David Pines published the articles in which they introduced the random phase approximation and proposed the plasmon.[24][25][26]

Bohm and Aharonov form of the EPR paradox[edit]

In 1955 Bohm relocated to Israel, where he spent two years working at the Technion, at Haifa. There, he met Sarah ("Saral") Woolfson, whom he married in 1956.

In 1957, Bohm and his student Yakir Aharonov published a new version of the Einstein–Podolsky–Rosen (EPR) paradox, reformulating the original argument in terms of spin.[27] It was that form of the EPR paradox that was discussed by John Stewart Bell in his famous paper of 1964.[28]

Aharonov–Bohm effect[edit]

Schematic of double-slit experiment in which Aharonov–Bohm effect can be observed: electrons pass through two slits, interfering at an observation screen, with the interference pattern shifted when a magnetic field B is turned on in the cylindrical solenoid.

In 1957, Bohm relocated to the United Kingdom as a research fellow at the University of Bristol. In 1959, Bohm and Aharonov discovered the Aharonov–Bohm effect, showing how a magnetic field could affect a region of space in which the field had been shielded, but its vector potential did not vanish there. That showed for the first time that the magnetic vector potential, hitherto a mathematical convenience, could have real physical (quantum) effects.

In 1961, Bohm was made professor of theoretical physics at the University of London's Birkbeck College, becoming emeritus in 1987. His collected papers are stored there.[29]

Implicate and explicate order[edit]

At Birkbeck College, much of the work of Bohm and Basil Hiley expanded on the notion of implicate, explicate, and generative orders proposed by Bohm.[3][30][31] In the view of Bohm and Hiley, "things, such as particles, objects, and indeed subjects" exist as "semi-autonomous quasi-local features" of an underlying activity. Such features can be considered to be independent only up to a certain level of approximation in which certain criteria are fulfilled. In that picture, the classical limit for quantum phenomena, in terms of a condition that the action function is not much greater than Planck's constant, indicates one such criterion. They used the word "holomovement" for the activity in such orders.[32]

Holonomic model of the brain[edit]

In a holographic reconstruction, each region of a photographic plate contains the whole image.

In collaboration with Stanford University neuroscientist Karl H. Pribram, Bohm was involved in the early development of the holonomic model of the functioning of the brain, a model for human cognition that is drastically different from conventionally-accepted ideas.[4][failed verification] Bohm worked with Pribram on the theory that the brain operates in a manner that is similar to a hologram, in accordance with quantum mathematical principles and the characteristics of wave patterns.[33]

Consciousness and thought[edit]

In addition to his scientific work, Bohm was deeply interested in exploring the nature of consciousness, with particular attention to the role of thought as it relates to attention, motivation, and conflict in the individual and in society. Those concerns were a natural extension of his earlier interest in Marxist ideology and Hegelian philosophy. His views were brought into sharper focus through extensive interactions with the philosopher, speaker, and writer Jiddu Krishnamurti, beginning in 1961.[34][35] Their collaboration lasted a quarter of a century, and their recorded dialogues were published in several volumes.[36][37][38]

Bohm's prolonged involvement with the philosophy of Krishnamurti was regarded somewhat skeptically by some of his scientific peers.[39][40] A more recent and extensive examination of the relationship between the two men presents it in a more positive light and shows that Bohm's work in the psychological field was complementary to and compatible with his contributions to theoretical physics.[35]

The mature expression of Bohm's views in the psychological field was presented in a seminar conducted in 1990 at the Oak Grove School, founded by Krishnamurti in Ojai, California. It was one of a series of seminars held by Bohm at Oak Grove School, and it was published as Thought as a System.[41] In the seminar, Bohm described the pervasive influence of thought throughout society, including the many erroneous assumptions about the nature of thought and its effects in daily life.

In the seminar, Bohm develops several interrelated themes. He points out that thought is the ubiquitous tool that is used to solve every kind of problem: personal, social, scientific, and so on. Yet thought, he maintains, is also inadvertently the source of many of those problems. He recognizes and acknowledges the irony of the situation: it is as if one gets sick by going to the doctor.[35][41]

Bohm maintains that thought is a system, in the sense that it is an interconnected network of concepts, ideas and assumptions that pass seamlessly between individuals and throughout society. If there is a fault in the functioning of thought, therefore, it must be a systemic fault, which infects the entire network. The thought that is brought to bear to resolve any given problem, therefore, is susceptible to the same flaw that created the problem it is trying to solve.[35][41]

Thought proceeds as if it is merely reporting objectively, but in fact, it is often coloring and distorting perception in unexpected ways. What is required in order to correct the distortions introduced by thought, according to Bohm, is a form of proprioception, or self-awareness. Neural receptors throughout the body inform us directly of our physical position and movement, but there is no corresponding awareness of the activity of thought. Such an awareness would represent psychological proprioception and would enable the possibility of perceiving and correcting the unintended consequences of the thinking process.[35][41]

Further interests[edit]

In his book On Creativity, quoting Alfred Korzybski, the Polish-American who developed the field of General Semantics, Bohm expressed the view that "metaphysics is an expression of a world view" and is "thus to be regarded as an art form, resembling poetry in some ways and mathematics in others, rather than as an attempt to say something true about reality as a whole".[42]

Bohm was keenly aware of various ideas outside the scientific mainstream. In his book Science, Order and Creativity, Bohm referred to the views of various biologists on the evolution of the species, including Rupert Sheldrake.[43] He also knew the ideas of Wilhelm Reich.[44]

Contrary to many other scientists, Bohm did not exclude the paranormal out of hand. Bohm temporarily even held Uri Geller's bending of keys and spoons to be possible, prompting warning remarks by his colleague Basil Hiley that it might undermine the scientific credibility of their work in physics. Martin Gardner reported this in a Skeptical Inquirer article and also critiqued the views of Jiddu Krishnamurti, with whom Bohm had met in 1959 and had had many subsequent exchanges. Gardner said that Bohm's view of the interconnectedness of mind and matter (on one occasion, Bohm summarized: "Even the electron is informed with a certain level of mind."[45]) "flirted with panpsychism".[40]

Bohm dialogue[edit]

To address societal problems during his later years, Bohm wrote a proposal for a solution that has become known as "Bohm Dialogue", in which equal status and "free space" form the most important prerequisites of communication and the appreciation of differing personal beliefs. An essential ingredient in this form of dialogue is that participants "suspend" immediate action or judgment and give themselves and each other the opportunity to become aware of the thought process itself. Bohm suggested that if the "dialogue groups" were experienced on a sufficiently-wide scale, they could help overcome the isolation and fragmentation that Bohm observed in society.

Later life[edit]

Bohm continued his work in quantum physics after his retirement, in 1987. His final work, the posthumously published The Undivided Universe: An Ontological Interpretation of Quantum Theory (1993), resulted from a decades-long collaboration with Basil Hiley. He also spoke to audiences across Europe and North America on the importance of dialogue as a form of sociotherapy, a concept he borrowed from London psychiatrist and practitioner of Group Analysis Patrick de Maré, and he had a series of meetings with the Dalai Lama. He was elected Fellow of the Royal Society in 1990.[1]

Near the end of his life, Bohm began to experience a recurrence of the depression that he had suffered earlier in life. He was admitted to the Maudsley Hospital in South London on 10 May 1991. His condition worsened and it was decided that the only treatment that might help him was electroconvulsive therapy. Bohm's wife consulted psychiatrist David Shainberg, Bohm's longtime friend and collaborator, who agreed that electroconvulsive treatments were probably his only option. Bohm showed improvement from the treatments and was released on 29 August, but his depression returned and was treated with medication.[46]

Bohm died after suffering a heart attack in Hendon, London, on 27 October 1992, aged 74.[47]

The film Infinite Potential is based on Bohm's life and studies; it adopts the same name as the biography by F. David Peat.[48]

Reception of causal theory[edit]

In the early 1950s, Bohm's causal quantum theory of hidden variables was mostly negatively received, with a widespread tendency among physicists to systematically ignore both Bohm personally and his ideas. There was a significant revival of interest in Bohm's ideas in the late 1950s and the early 1960s; the Ninth Symposium of the Colston Research Society in Bristol in 1957 was a key turning point toward greater tolerance of his ideas.[49]
