Happy Birthday to You, Chandra!

Today (Oct. 19) is the 108th birthday of Subramanyan Chandrasekhar about whom I have read the past year or two. I was going to write “S. Chandrasekhar: a Renaissance man in science” in my blog as this astrophysicist and mathematician is the best example, the most intellectual of intellectuals. Only his close friends and colleagues called him Chandra. I would flatter myself presuming he has allowed me to call him Chandra.

I have decided to delay writing the post until I finish reading two books about him (one is his biography, the other is about a famous debate in science that involved him.) and one ebook I just bought from Amazon after I found out it is not available at Carnegie Library. The book is called Truth and Beauty: Aesthetics and Motivations in Science (I kept saying reading in science and humanity is to pursue truth and beauty), a collection of his seven lectures.

I was a bit disappointed when I discovered the lecture of “Shakespeare, Newton and Beethoven” is part of the 7 lectures in the book, that means my $17 or $18 just bought 6 lectures, instead of 7, as that lecture is readily available free online. Almost every book I bought the past year or two are all ebooks, I did this with mixed emotions, it is not the money issue, as the ebooks are usually a few dollars less expensive only.

Instead I will just say “a few words” to say Happy Birthday to You, Chandra!”

After reading the “Shakespeare, Newton and Beethoven” (talking about different creative pattern in art and in science) drove me to pursue him further, the more I read about him, the more I hold him in awe.  He said that he “received the same thrill from a Michelangelo sculpture as from a beautiful mathematical relationship.”

An intellectual family of distinction
Chandrasekhar is from an intellectual family of distinction. His uncle, Sir Chandrasekhar Venkata Raman was awarded a Nobel Prize in Physics in 1930. Chandra wrote, “my mother was a woman of high intellectual attainments. She translated into Tamil, for example, Henrik Ibsen’s A Doll House.” His grandfather was a university mathematics professor.

In his first series of “現代俳句 & 變奏, 系列 1” in June 2017, my friend, Khang-Loon wrote,

「最近好嗎?都想些什麼?」. [How are you doing of late? What are you all thinking about?]
Black Hole, Dark Matter, Supernova, . . .
到遠方自成一個宇宙 [forming a universe of its own far away.]

The beauty of the mathematical theory of black holes
(This is how Chandrasekhar begins his Nobel Lecture)
Khang-Loon seemed to know what I was reading, and reading Black Holes, one cannot escape B. Chandrasekhar, whose Nobel Lecture in 1983 is all complex math from the beginning to the end. I wish I could read his book of the Mathematical Theory of Black Holes. The Lecture ends with,

the mathematical theory of black holes is a subject of immense complexity; but it’s study has convinced me of the basic truth of the ancient mottoes, and

The simple is the seal of the true
and
Beauty is the splendor of truth.

A genius and an Newton Expert
If Genius is defined as having enormous intellect, then Chandrasekhar is one. The complex math that leads to the now known as Chandrasekhar Limit (for which he was awarded Nobel Prize in Physics 53 years later) was done during his 3-week voyage from India to England, heading to Cambridge University (Trinity College; Newton's college. Chandra is an expert on Isaac Newton. He translated the Principia into the language of modern mathematics, he wrote a book of “Newton's Principia for the Common Reader”) in 1930. He was then a 19-year-old young man, just graduating from Presidency College at Madras.

Chandra studied with the giants in science and in the three “holy” institutes where the quantum mechanics was born and flourished
He studied and researched under Ralph Fowler at Trinity College. In 1931 Max Born (who is the maternal grandfather of Olivia John Newton) invited Chandrasekhar to study at Gottingen Institute. At the advice of Paul Dirac, he spent the last year of graduate studies at the Institute for Theoretical Physics in Copenhagen, where he met Bohr. So he actually studied at the three “holy” institutes where the quantum mechanics was born and flourished.

Did the racial discrimination drive Chandra from England to America?
Chandrasekhar moved to the United States (University of Chicago) in 1937. I have read from many sources that racial discrimination was what drove him away from England. This involves Sir Arthur Eddington who ridiculed him at a meeting of the Royal Astronomical Society. Chandrasekhar praised the US saying, “I have one advantage here in the United States. I have enormous freedom. I can do what I want. Nobody bothers me”. This is one of the main reasons why I delayed the writing about him. I need to get to the bottom of the truth.




Devotion to his student is legendary
Legend had it that while working at Yerkes Observatory (in Wisconsin, affiliated with University of Chicago), he drove 75 miles one way every weekend to teach a course with only two students: Tsung-Dao Lee (李政道)and Chen-Ning Yang (楊振寧)who got Nobel Prize in 1957, Chandrasekhar had to wait another 26 years for his glory. In his obituary at New York Times, I read that NY Times called Chen-Ning Yang who said the story of driving was true, but “he thought there were others in the course.” (Another small example that NY Times is more trustful.) Carl Sagan was also his student, who described his interaction with students that “frivolous questions” from unprepared students were “dealt with in the manner of a summary execution”, while questions of merit “were given serious attention and response.”

During WWII he worked in Maryland on ballistics for the war effort, and The NY Times obituary, along with many other sources, reported he turned down Oppenheimer’s invitation to join those at Los Alamos working on Manhattan Project. But I also read different version of the story saying his failure to participate is due to security clearance delay. Another reason that I have to read more to get to the truth.

A master in English language and the breadth and depth of the knowledge in literature and arts
His Nobel Lecture is beyond us, but we can appreciate his Nobel Banquet speech which is mainly composed of two relatively lengthy quotes: One from Virginia Woolf’s (about whom I have read for many years; there is a category of "Virginia Woolf" in this blog.) The Waves (of many novels she wrote, she liked this one the most.) Chandrasekhar once compared the prose of his favorite novelist, Virginia Woolf, to “an elegant mathematical formula.”

He quoted Ravindranath Tagore’s poem and said, “I learnt the poem when I was a boy of twelve some sixty and more years ago; and the following lines have remained with me ever since:

Where the mind is without fear and the head is held high;
Where knowledge is free;
Where words come out from the depth of truth;
Where tireless striving stretches its arms toward perfection;
Where the clear stream of reason has not lost its way into the dreary desert sand of dead habit;
Into that haven of freedom, Let me awake.

Dr Greenlee and I: The poster boys of American Lung Association
Hans Bethe, a fellow Nobel laureate, the one I greatly admire as a scientist as well as a person (who died the same day as our neighbor, Dr. Paul Greenlee, a Mayo Clinic-trained surgeon, in 2005), had high praise of Chandra, “one of the great astrophysicist of our time. He was also the greatest master of the English language that I know.” His deep and broad knowledge of literature and arts greatly match his enormous scientific achievements.


Chandra gave a lecture of “The Series Paintings of Claude Monet and the Landscape of General Relativity” at Presidency College, Madras, in 1992, three years before his passing. It took place in the room where he had courted his wife, Lalitha, sitting at his side, more than sixty years earlier.

A wedding at the colorful mountain

I would not wish any companion in the world but you!
              The Tempest: Act 3, Scene 1

The sight of lovers feedeth those in love
             As you like it: Act 3, Scene 4

Juliet
My bounty is as boundless as the sea,
My love as deep, the more I give to thee
The more I have, for both are infinite.
