Samuel C. C. Ting

Samuel Chao Chung Ting (

More recently he has been the principal investigator in research conducted with the Alpha Magnetic Spectrometer, a device installed on the International Space Station in 2011.

Biography

Ting was born on January 27, 1936, in Ann Arbor, Michigan to first generation Chinese immigrant parents, who both hail from Ju County, Shandong province.^[1] His parents, Kuan-hai Ting and Tsun-ying Wong, met and married as graduate students at the University of Michigan.^[2]

Ting's parents returned to China two months after his birth

In 1956, Ting, who barely spoke English,[3] returned to the United States at the age of 20 and attended the University of Michigan. There, he studied engineering, mathematics, and physics. He received Bachelor of Science in Engineering degrees in mathematics and in physics in 1959 and a Doctor of Philosophy degree in physics in 1962.^[6][7]

In 1963, Ting worked at the European Organization for Nuclear Research (CERN). From 1965, he taught at Columbia University in the City of New York and worked at the Deutsches Elektronen-Synchrotron (DESY) in Germany. Since 1969, Ting has been a professor at the Massachusetts Institute of Technology (MIT).

Ting received the Ernest Orlando Lawrence Award in 1976, Nobel Prize in Physics in 1976, Eringen Medal in 1977, DeGaspari Award in Science from the Government of Italy in 1988, Gold Medal for Science from Brescia, Italy in 1988, and the NASA Public Service Medal in 2001.^[4]

Nobel Prize

In 1976, Ting was awarded the

In reality, a theory in natural science cannot be without experimental foundations; physics, in particular, comes from experimental work. I hope that awarding the Nobel Prize to me will awaken the interest of students from the developing nations so that they will realize the importance of experimental work.[10]

Alpha Magnetic Spectrometer

In 1995, not long after the cancellation of the Superconducting Super Collider project had severely reduced the possibilities for experimental high-energy physics on Earth, Ting proposed the Alpha Magnetic Spectrometer, a space-borne cosmic-ray detector. The proposal was accepted and he became the principal investigator and has been directing the development since then. A prototype, AMS-01, was flown and tested on Space Shuttle mission STS-91 in 1998. The main mission, AMS-02, was then planned for launch by the Shuttle and mounting on the International Space Station.^[11]

This project is a massive $2 billion undertaking involving 500 scientists from 56 institutions and 16 countries.^[12] After the 2003 Space Shuttle Columbia disaster, NASA announced that the Shuttle was to be retired by 2010 and that AMS-02 was not on the manifest of any of the remaining Shuttle flights. Dr. Ting was forced to (successfully) lobby the United States Congress and the public to secure an additional Shuttle flight dedicated to this project. Also during this time, Ting had to deal with numerous technical problems in fabricating and qualifying the large, extremely sensitive and delicate detector module for space.^[13] AMS-02 was successfully launched on Shuttle mission STS-134 on May 16, 2011, and was installed on the International Space Station on May 19, 2011.^[14][15]

Research

• Discovery of nuclear anti-matter (the anti-deuteron).^[16]
• Measuring the size of the electron family (the electron, the muon, and the tau) showing that the electron family has zero size (with a radius smaller than 10⁻¹⁷ cm).^[17]
• Precision study of
  light rays and massive light rays showing that light rays and massive light rays (vector mesons) can transform into each other at high energies and providing a critical verification of the quark model.^[18][19]

  atomic nuclei.^[20]
• Discovery of a new kind of matter (the
  J particle)^[21] at the Brookhaven National Laboratory. The Nobel Prize
  was awarded to Ting for this discovery.

Personal life

Ting lived in a turbulent age during his childhood and his family was a big influence on him. In his biographical for the Nobel Prize, he recalled:

Since both my parents were working, I was brought up by my maternal grandmother. My maternal grandfather lost his life during the first Chinese Revolution. After that, at the age of thirty-three, my grandmother decided to go to school, became a teacher, and brought my mother up alone. When I was young I often heard stories from my mother and grandmother recalling the difficult lives they had during that turbulent period and the efforts they made to provide my mother with a good education. Both of them were daring, original, and determined people, and they have left an indelible impression on me.

When I was twenty years old I decided to return to the United States for a better education. My parents' friend, G.G. Brown, Dean of the School of Engineering, University of Michigan, told my parents I would be welcome to stay with him and his family. At that time I knew very little English and had no idea of the cost of living in the United States. In China, I had read that many American students go through college on their own resources. I informed my parents that I would do likewise. I arrived at the Detroit airport on 6 September 1956 with $100, which at the time seemed more than adequate. I was somewhat frightened, did not know anyone, and communication was difficult.^[5]

Ting is the eldest son of his family. He has one brother, Ting Chao-hua (丁肇華) and one sister, Ting Chao-min (丁肇民). In an interview with

In 1960, Ting married Kay Louise Kuhne, an architect, and together they had two daughters, Jeanne Ting Chowning and Amy Ting. In 1985 he married Dr. Susan Carol Marks, and they had one son, Christopher, born in 1986.[5]
