- Wherever I go, I brag about my Princeton background. Thus, people ask
me the following questions.
- Am I the first Korean to receive a PhD degree from Princeton?
- Did I meet Einstein and talk to him?
The answer is No to both questions, but I have a story to tell.
- Syngman Rhee received his degree in
1910, and he is known as Woodrow Wilson's most accomplished student. He was
the first and founding president of the Republic of Korea (South Korea). He
was a dictator, but is regarded as the father of democracy in Korea modeled after
- When I went to Princeton as a first-year graduate student in 1958, Einstein
was already in heaven. How can you talk to a person in heaven?
Do you know how Moses talked to God? He wrote five books about God,
They are the first five books of the Old Testament.
- Click here to see how Moses talked to
God, and how I talked to Einstein.
- The best way to talk to Einstein is to write a book or books addressing the issues
in which Einstein was most interest. Einstein received his Nobel prize in
which is regarded as one of the most important formulas for our civilization.
Thus, the best way to talk to Einstein is to tell him what happened to this
formula since his time.
- Eugene Paul Wigner was regarded as the No. 2 man (after Einstein). He received
his Nobel prize in 1963, but
on his little groups dictating the internal space-time symmetries of particles
in Einstein's Lorentz-covariant world.
In 1986, I told Professor Wigner that his 1939 paper deserved one full Nobel prize
as Einstein's E = mc2 does, by showing the following table.
Contents of Einstein's E = mc2
| E = p2/2m

| E = cp

- This table forces us to go back to the century-old problem. One hundred years ago,
Niels Bohr was worrying about discrete energy levels of the hydrogen atom. Einstein
was interested in how things look to moving observers. Bohr and Einstein met occasionally
to talk about physics. Did they ever talk about moving hydrogen atoms. The answer
seems to be No. Thus, there are two distinct routes to take.
- Since they did not ask this problem, we should resolve this issue.
- Since they did not address this issue, the problem does not exist. It is foolish
to waste time on the problem that does not exist.
- Which route would you take? Before 1950, the hydrogen atom moving with
relatistic speed was unthinkable. It is still unthinkable. Howwer, these days,
high-energy acclerators routinely produce protons moving with speeds very close
to that of light. While the proton is not a hydrogen atom, it is a quantum
bound state just like the hydrogen atom, according to Murray Gell-Mann (1964).
When the proton moved with an ultra-fast speed, it appears like a collection
of partons, according to Ricard Feynman (1969).
Thus, the resolution of this quark-parton provides an answer to the
Bohr-Einstein issue of the moving hydrogen atom.

This table contains my earlier work, mostly with Marilyn Noz, on how
the proton (quantum bound state like the hydrogen atom) appears when it
moves with a speed close to that of light. This is known as the
quark-parton puzzle in high-energy physics.

Richard Philips Feynman (1919-1988)
- Richard Feynman
was the most creative American physicist in the 20th Century. He received
his PhD degree in 1942. His thesis advisor was John A. Wheeler.
- In 1966, I received a death
sentence (ordering me to stop doing physics) from the physics community for
publishing a paper not consistent with Princeton's view. I survived only
because Feynman in 1970 expressed his view consistent with mine. From there,
I regained my courage.
Feynman was my Savior.
- It is fun to talk about
I maintain my own Feynman site. Feynman was a very colorful person.
You will also be interested in the following pages.
- Artist. Feynman was an artist. He used
to draw pictures when he was doing physics. This resulted in Feynman diagrams.
- Rio de Janeiro. Feynman used to
there very often to join Brazil's Samba artists.
- According to
Feynman, the adventure of our science of physics is a perpetual
attempt to recognize that the different aspects of nature are really
different aspects of the same thing.
- Feynman published approximately 150 papers. Thus it is fun to see whether
those papers can be combined into one. I could not do this, but I was
able to combine three of them into one.

- Eugene Wigner also published many papers.
In 1939, Wigner published his paper on internal space time symmetries
of elementary particles. In 1953 with Inonu,
he published a paper on group contractions. It is fun to combine those into
- Paul A. M. Dirac was another great physicist of the past century. He was a
beautiful writer, and his papers are like poems. However, his paper does not
contain any figures or illustrations. On the other hand, Feynman was a cartoonist.
He drew pictures and diagrams to express his ideas. Thus, it is fun to translate
Dirac's poems into cartoons.
- I published about 200 papers. According to Feynman's definition of physics,
I should be able to combine all those into one paper. This is not an easy job.

a PC at that time.
