Vienna, Austria

• Vienna Opera House has a very rich history. On December 31 of every year, the Opera House presents Johann Strauss's Die Fledermaus. You have to reserve your ticket one year in advance. Of course you can negotiate tickets at black market for about $300, but I do not trust those black marketers. I was there on December 31 (2006) but could not get in.
  1. Another View of the Opera House.
  2. I was inside in 2007. After the performance of Coppelia by Leo Delibes (2007).
  3. Higher Rings seen from an orchestra seat.

• Vienna Stadtpark is a great music place. Birds sing during the summer.
  1. Vienna Hilton is one block away from the Park. I stay here often because the airport connection is very convient.
  2. Johann Strauss at the Park. Strauss is the eternal mayor of Vienna.
  3. Side View of the Johann Strauss statue.
  4. Franz Schubert in the Park.
  5. Franz Lehar is also there.
  6. There are many more, and they are all around the Park's reflection pond.

• Kursalon is a music theater dedicated to Johann Strauss. It is located at the southwestern corner of the Stadtpark, as can be seen from the Park.
  1. This is the entrance to the theater.
  2. I was there on January 1, 2007.
  3. I was inside for a Mozart Festival (1997). Since I do not know how to dance, I had to watch other people dance.

• Schonbrun Plaza is another great music place in Vienna.
  1. Let us watch one of the summer music festivals.
  2. How about the new year's eve? I was there in the evening of 2006-2007.
  3. Mozart dress at Chonbrunn's music theater.

  4. Musikverein (2007). The New year's waltz concert is held at this music hall every year and is broadcast throughout the world. I was inside in October of 2007 for a Mozart festival.
  5. Vienna Volk Art Theater near the Parlianment Building.

• Augustinerkeller is a Viennese restaurant serving Viennese dishes. I was there in 2000 and shared a dinner table from Germans from Munich. I was returning home from a conference held in Kharkov (Ukraine). Due to airline connections, I have to spend one night in Vienna.
  1. In 2006, I went there again, and asked the same accordionist to play "Over the Waves" by a Mexican composer named Juventano Rosas. This is a non-Viennese waltz, but he knew how to play. I was very happy because it was my childhood favorite.

• Vienna McDonald's near the campus of the University of Vienna.
• Nordsee. There are many Nordsee restaurants in Vienna, and you can meet many interesting people. In this photo, I am with students from Croatia.
• Viennese Lunch. There are many sidewalk cafes, and you can taste Viennese dishes at a reasonable price.
• New Year's Eve Dinner at the resaurant Prachutta (December 31, 2006).

• St. Stephen's Cathedral. Vienna's address No. 1. Vienna is not a large city. Every place is within a walking distance from this Cathedral. We thank Peter Kasperkovitz for contributing this excellent photo taken from the highest point at the Technical University of Vienna.
  1. Church of St. Francis of Assisi is one of the most elegant buildings in Vienna. It is commonly called the Mexican Church. I cannot explain the history of this church too well. You can visit the Wikipedia page to read more about this impressive-looking cathedral.
  2. One of the government buildings in Palladian style.

• Greek Temple at the Volsksgarten. Viennese seem to be in love with Greek architecture. Emperor Franz Joseph (1830-1916) believed in Greek culture.
  1. Woman Columns like these can be seen at many places. They are copied from the original Greek columns on the Akropolis Hill in Athens constrcted 2,400 years ago.
  2. Congress Building. You cannot tell this is a governmnent building for Greece or Austria.
  3. Greek Columns inside the Congress building.
  4. Greek-style Podium in one of the assembly halls.
  5. Greek Wall in the back of the hall.

I have many more photos to add to thie webpage. Please come again.

Erwin Schroedinger's Vienna

• I heard about his hydrogen wave function from Lincoln Wolfenstein in 1956 when I was in my junior (3rd) year at Carnegie Tech. In my senior year, I took the first-year quantum mechanics from Michel Baranger. I learned from him that the energy levels for bound states are discrete because their wave functions should satisfy the localization boundary condition.

• In the 1960s, bound states were coming from poles from the S matrix, it was illegal to say otherwise. How about bound-state perturbation theory? Of course, it is a small displacement of the pole position. However, I still needed wave functions to understand this.

  I made my debut in the physics as an independent thinker by making a case about it. The question is whether the displacement of the pole position preserves the wave function localization. I showed that the bound-state wave function from a displaced pole position is not localized and thus becomes a bad wave function.

• You may click here for a detailed story.

  In order to discredit what I say, some responsible people said the wave function has nothing to do with physics. This was of course an idiotic statement, but genius can learn something from idiot while idiot cannot learn anything from genius. I carefully studied whether there is anything wrong with wave functions.

• Yes! There was one important unsolved problem. How would the above "good" and "bad" wave functions look to my friend on a train where space and time variables are mixed? Is the wave function localization (standing wave) consistent with Einstein's Lorentz covariance? How can he/she explain what I do in terms of the language available in his/her frame. You may click here for illustrations.

  I could not solve this problem for all the wave functions on earth, but could provide a satisfactory answer for one case, namely that of harmonic oscillator wave functions. In so doing, I was able to explain the quark model and the parton model are two limiting cases of one covariant entity. You may click here for a detailed story. I have been working on this problem with Marilyn Noz since 1970 (nearly 40 years).

  Schroedinger (top) and Boltzmann at the Univ. of Vienna.

• In addition to Erwin Schroedinger, we constantly talk about Ludwig Boltzmann. We cannot do physics without Boltzmann's constant. Other than that, I cannot tell you too much about him other than what you already know.

  Feynman talks about entropy in his book on statistical mechanics. Feynman says

  When we solve a quantum-mechanical problem, what we really do is divide the universe into two parts - the system in which we are interested and the rest of the universe. We then usually act as if the system in which we are interested comprised the entire universe. To motivate the use of density matrices, let us see what happens when we include the part of the universe outside the system.

  Do you understand what he says? The best way to decode what Feynman says is to work out his ideas. It is always fun to examine Feynman's provocative statement. You may click here to see what Feynman was talking about.

• You might also be interested in hearing about what I discussed with Eugene Wigner on this issue. Wigner was wondering whether Entropy could be a variable having to do with Lorentz transformations. I was able to entertain him by telling the story based on my experience with harmonic oscillators and Feynman's rest of the universe. Here is a paper which I published with Wigner on this subject.

• Sigmund Freud is another prominent person from Vienna. We all know how he formulated the science of psychology. To a man's psychology, women play very important roles. Ancient Chinese derived an abstract concept of "good" by combining a woman with her son. The Chinese character for good consists of woman and son.

  The portrait of a woman holding her infant son plays the pivotal role in the western religion called Christianity. With this point in mind, I have constructed a webpage consisting of relevant photos.

  About 2,500 years ago, a Chinese scholar named Sun Tzu wrote a book entitled Art of War. My maternal grandfather was able to read his book in Chinese and told me stories about what Sun Tzu said.

• After learning about Freud, I came to the conclusion that Sun Tzu formulated a psychology based on man's desire to fight and win. This means that I am armed with Sun Tzu's psychology to fight and win. This is the reason why I was able to ward off the shady games some of my colleagues attempted to play against me in the past.

  In addition, I have a strong Christian background. By combining the story about the birth of Jesus with Sun Tzu's psychology, I was able to formulate the concept of Herod Complex. If you are a physicist, you are burdened to carry your herod complex.

  Victor Weisskopf (1908-2002) was born in Vienna but went to Germany to study. He came to the United States before World War II and worked on the Manhattan project developing the first nuclear bomb. While in Europe, he worked with Schroedinger, Heisenberg, Pauli, and Bohr. His dissertation advisor was Eugene Wigner at the Technical University of Berlin. After World War II, he became an important person at MIT, and was also one of the founding members of CERN. Yet, he always called himself as a Viennese physicist. Vienna was dearest to his heart.

  I only have limited contacts with him, but he was always like my uncle. He was three years older than my father. When I was hosting the first Wigner Symposium in 1988, I invited him to deliver a banquet speech. Here is a photo of Weisskopf speaking at the banquet.

  In this photo, Weisskopf is very happy to listen to Wigner's speech. I was able to arrange a photo of Wigner with his first student (Weisskopf) and his youngest student (Francis Narcowich). Here is the photo.

  I met Weisskopf for the last time in 1997 at MIT. I shared a banquet table with him and also with Francis Low. He was very weak and showing a sign of his age, and was not able to eat much. He was talking about the struggles he went through. Yet, he was very proud of being a Viennese physicist.

  There is another Viennese physicist whose name is quite familiar to us. You can recognize who he is from this photo. Whenever you attend a conference on quantum optics, quantum information, or foundations of quantum mechanics, he is a plenary speaker. Like Weisskopf, he is very approachable, and it is very easy to have a photo with him.

  I have a strange habit of talking to everybody in restaurants, hotels, shops, or on the streets. When I talk in Vienna, those Austrians ask me where I came from. When I say U.S.A., they ask me whether I know Arnold Schwarzenegger came from Austria. They ask me where I originally came from. I then point to the Samsung sign visible everywhere in the world.

  They then ask me what my profession is. Then I show them this photo. I also become an important person to them. I hope I can make a webpage for him in the near future.

  How did I talk to Einstein?

  1. Click here for his home page.
  2. His photo-biography.
  3. His Einstein page.
  4. His Princeton page.
  5. His Style page.

  
  I received my PhD degree from Princeton in 1961, seven years after high school graduation in 1954. This means that I did much of the ground work for the degree during my high school years.
