Sixty Years Since 1962
Physics faculty photo of Spring 1963 (during my first year at the University).
I am the youngest person in this photo.
- In 1962, I came to the Greater Washington area to become an assistant professor
of physics at the University of Maryland. The campus is 25 km north of the White House.
In 2007, I became a Professor Emeritus (without teaching duties) and am writing books and
articles. I can travel around the world wihout time restrictions,
and I enjoy meeting interesting people.

- In 1962, Paul A. M. Dirac (Nobel 1933) visited the University of Maryland
for one week, and I was assigned to be a personal assistant (servant) to him.
I learned his physics
directly from him. I was like Nicodemus meeting Jesus (story from
the Gospel of John in the New Testament). I was born again, and I was able
to develop my own research line
I still follow.
Dashen made this bad calculation in 1965, but he never admitted his
- In 1965, while I was struggling to find out myself, the physics community produced
the genius of the century named Roger Dashen who calculated the mass the neutron-proton
mass difference. He was appointed as a full professor at Princeton's Institute for
Advanced Study (Einstein's place until he died in 1955).
I have my Herod complex, and
become uneasy when I hear someone (other than myself) is a genius. I had to prove
his published papers were wrong, and I published my papers saying so.

However, the reaction from the American physics community became hostile to me.
My colleagues and teachers told me
Dashen is a genius, but you are a Korean.
This was a very valid statement in the United States at that time, and I
still (not too often) hear similar prejudicial remarks in the academic
While I was at Princeton (1958-62), my friends routinely told me
Koreans cannot run their own country. The best solution is to
give Korea back to Japan.
The orientals do not have brains to make nuclear bombs.
My only possible response was to remain silent.
Yet, my colleagues in the same department made their best efforts to find out
whether Dashen was right or I was right. They found out I was right. This
is the reason why I still have my office at the University, and I publish my
books and papers with the university address.
The fact that Princeton made this tragic misjudgment is known as the
and this incident inflicted a serious damage to Princeton's reputation.
Yet, Princeton kept producing excitements by producing new words. The
latest word from Princeton is the String Model and String Theory. I do
not know what happened to these string stuff.
As for me, I had to build my own research line. I could not trust Princeton,
but I coult not give up my Princeton background.
- While I was at Princeton, Eugene Paul Wigner (Nobel 1963) was totally isolated
from the rest of the department. Yet, I had a great respect for him, and started
studying his 1939 paper on
internal space-time symmetries.

- I had to go back to what I learned from
Dirac (Nobel 1933) in 1962.
for my Dirac page.
Based on these two cornerstones, I was able to develop and expand my own
research line described in
Let me summarize. The United States rewards those who work hard. I worked hard,
and was able to produce this genealogy in physics:
Life in the Greater Washington Area since 1962
- Washington DC is the capital city of the United States. The city of Washington
is geographically within the state of Maryland. The University Maryland is 25 km
north of the White House.
Washington was a sleepy southern town when I came to this area 1962.
Since then the world became different. China became very powerful. Europe
became much richer. The Soviet Union collapsed. The net result is that the
United States became more influential, and Washington became the capital city
of the World.
- One unknown fact is that there are far more scientists than politicians in the
- Politicians are noisy while scientists are quiet.

- In 1963, I married a girl I met during my freshman year (1954) in
Korea. In Korea, the school year begins in March, instead of September.
I thus spent one semester at the Engineering College of
Seoul National University before becoming a freshman in September at the
Carnegie Institute of Technology in Pittsburgh.
- In 1969, we bought
our house, 8 km north of the university campus. I used to work at
my university office during evening hours.
Our son's graduation at Princeton Univsersity in 1987.
- In 1983, our son became a freshman at Princeton University. Thus, my
wife was privileged to marry a Princeton man and sent her son to Princeton.
Here is her photo-bio.
- In 2005, my son married a medical doctor, and we now have one grandson and
granddaughter. They also live in the Washington area, and we have family
meetings twice a month.
- In 2007, I retired from my teaching duties at the University of Maryland,
and my wife retired earlier in 2002. We became free to travel around the world.
