  • On March 12, 1958, while I was a fourth-year student at Carnegie Tech in Pittsburgh, I received a letter from Princeton University telling me that I was one of the 15 students admitted to their graduate program. This was the happiest day in my life. Going to Princeton was working with Albert Einstein even though he went to Heaven three years earlier in 1955.

    Princeton was a small town and the university was a single-gender school (boys only) at that time. There were no excitements other than studying at the libraries. However, the city of New York was one-hour train ride from Princeton. I went to New York often and was able to enjoy all aspects of American life. I still maintain a webpage dedicated to the New York City.

    I worked hard at Princeton and got my PhD degree in 1961, and I was asked to stay there for one additional year as a post-doctoral fellow until 1962.

  • My thesis advisor was Sam Treiman. He was a good teacher and wrote good letters for me throughout my career. However, did he have enough scientific competence to support my research results after my PhD degree? My answer is No.

    I used to feel very bad about this, but not now.

    Most of the famous people accomplished more than their own teachers. I should be but am not famous enough (yet). Steven Weinberg (Nobel 1979) is very famous. Did you know his advisor at Princeton was also Sam Treiman?

    Weinberg got his degree in 1957, and I got mine in 1961. You may check the list of Treiman's student from Treiman's Wikipage.

  • In 1962, I was appointed as an assistant professor at the University of Maryland near the city of Washington, DC, and I started my professional career.

    While I was struggling to find out my own way of doing physics, the physics world produced a genius of the century in 1965. His name was Roger Dashen and became a full professor at the Princeton's Institute of Advanced Study. I became very unhappy because of my Herod Complex. Someone other than myself is a genius? Totally unacceptable to me.

  • I looked at Dashen's papers carefully and found a gross mistake in his reasoning. I then published my result in the Physical Review. Click here for a detailed story.

    However, was the American physics community going to accept my result? The answer was No. The average physicists were not smart enough to understand Dashen's papers or my papers. Thus, the reaction from the Amrican physics community was

      Dashen is a genius, but you are only a Korean.
      Go back to Korea!

    This was a very valid argument in the United States at that time (1960-80). Korea was regarded as a hopelessly underdeveloped country. Not knowing the history of that area earlier than the Pearl Harbor Day of 1941, my American friends used to tell me that the best solution of the Korean problem is to give the country to Japan.

  • Thus, my position at the University was in danger. The only person who could help me in this difficult situation was Sam Treiman, who was my thesis advisor at Princeton. I went to Princeton to explain to him the technical details of Dashen's mistake, but he did not have enough brain to understand my explanations. He became very angry, and his attitude toward me was "Never come to Princeton again!"

    In the meantime, the University of Maryland went through a very careful examination of my case by contacting all possible experts in the field, and determined that I was right. This is the reason why I maintained my office at the University campus, and publish books and articles with the University address. The United States has been very nice to me.

  • This means that I became alive and well again, but I could not use my Princeton background through my thesis advisor. Dashen was still a genius there. However, I could still use my Princeton connection if I change the the name of my advisor. How was it possible after the graduation?

    When I was a student there I noticed that Eugene Paul Wigner (Nobel 1963) was totally isolated from the rest of the physics department. The best way was to contact him, but how? The only way to contact was to tell him the story he wanted to hear. I got this idea from my piece of Korean wisdom.


What story did I tell Wigner?

  • Wigner published many papers, but his 1939 paper on his little groups was dearest to his heart. The paper deals with the internal space-time symmetries of particles in Einstein's Lorentz-covariant world.

    He was of course happy with his Nobel prize of 1963, but was not 100-percent happy because the prize was not for this paper of of 1939. He wanted to hear that this paper alone deserves one full Nobel prize. This is precisely what I told him in 1986, and I had to give the reason why.

    Earlier, after my disappointment with my thesis advisor in 1966, I studied Wigner's 1939 paper on the internal space-time symmetries of particles in Einstein's world. What does the word internal mean? Click here.

  • With my younger colleagues I published my papers in from 1983 to 1986 leading to this table:

    Einstein's World

    Massive/Slow between Massless/Fast
    Energy
    Momentum
    E=p2/2m Einstein's
    E=(m2 + p2)1/2
    E = cp
    Helicity
    Spin, Gauge
    S3
    S1 S2
    Wigner's
    1939 paper
    S3
    Gauge Trans.

  • Earlier in 1979, a Turkish physicist named Bulent Atalay constructed this portrait of Wigner with Einstein. Wigner was so happy with this portrait that he prominently displayed it in his office.

    With the table given above, I was able to tell Wigner that his 1939 paper is as important as Einstein's special theory of relativity which leads to the formula E = mc2.

    Wigner was so happy that he invited me to publish papers with him, and I wrote seven papers to make him happy. Since I published those papers with him, I became known as Wigner's youngest student at Princeton.

    Since I became Wigner's student particulary on the Einstein issue. I am able to show to the world, the following genealogy.

Paul A. M. Dirac was Wigner's brother-in-law.

  • When I came to the University of Maryland in 1962, I was the youngest faculty member of the physics department. John S. Tall was the ambitious chairman of the department. He invited Paul A. M. Dirac (Nobel 1933) to the University for one week, and assigned me as personal assistant to him. My friends in the department called me the "baby sitter" for him.

  • For me, this was the golden opportunity to learn physics directly from him. Since I was not happy what Princeton people were doing at that time, I was like Nicodemus listening from Jesus (story from the Gospel of John). Click here for the detailed story.

  • Even though Wigner's sister was Dirac's wife, and Dirac and Wigner met often, it is not clear whether they ever discussed physics when they were together. Wigner became very happy when I explained to him what Dirac did in the language he used in his 1939 paper.

  • Neither Dirac nor Wigner was familiar with the experimental results from high-energy accelerators during the second half of the 20th Century. It was the duty of younger generation of physicists. It was indeed a rewarding experience for me to offer my explanation of what we see in the real world in terms of the theoretical devices developed by these two "famous brothers-in-law.

  • I was able to summarize Dirac's lieftime efforts andd synthesize them as

    The question then is whether this figure has anything to with what we see in the world. Click here.
