ABOUT THE PRESENTER |
John Cahn’s research
interest are in the development of principles needed for materials
science, with emphasis on microstructure evolution. Two partial
differential equations, that grew out of his work, are widely studied
and used. He is also interested in thermodynamic principles and
their application to stressed solids, to anisotropic surfaces and
interfaces, and to kinetics. As an outgrowth of a study of rapid
solidification in the early 1980s he participated in the discovery
of icosahedral quasiperiodic crystals. He has published about 250
papers.
He is a Senior Fellow at the Materials Science and Engineering Laboratory
of the National Institute of Standards and Technology (formerly
NBS) in Gaithersburg, Maryland, where he has been for 26 years.
He received his B.S. in Chemistry in 1949 from the University of
Michigan, and his Ph.D in Physical Chemistry in 1953 from the University
of California at Berkeley. He holds honorary doctorates from Northwestern
University and Université d’Evry in France.
Prior to coming to NBS, he held positions at the University of Chicago’s
Institute for the Study of Metals (now the James Franck Institute),
at the GE Research Laboratory during the Hollomon era in the group
founded by David Turnbull. From 1964 until 1978 he was a Professor
of Metallurgy at MIT. In 1960 he was awarded a Guggenheim fellowship,
which he spent at Cambridge University. He has been a visiting professor
in Sweden, Israel, and Iran, and since 1984 an affiliate professor
jointly in physics and materials engineering at the University of
Washington in Seattle. His many awards and honors include: the Bower
Prize from the Franklin Institute, the 1998 National Medal of Science,
memberships in the National Academy of Sciences, the National Academy
of Engineering, and the American Academy of Arts and Sciences, the
Dickson Prize of Carnegie-Mellon University, the Michelson- Morley
Award of Case-Western University, the Harvey Prize from the Technion
in Israel, Fellow of both TMS and ASM, ASM’s Sauveur and Hume-Rothery
Awards, the Acta Metallurgica gold medal, NBS’s Stratton award,
and a gold medal from the US Department of Commerce, the Bakhuis-Roozeboom
medal from the Dutch Academy of Science, a gold medal from the Japan
Institute of Metals. and the Emil Heyn medal from the German Materials
Society (DGM). He has gave the Institute of Metals Lecture (now
the Mehl Lecture) of TMS in 1967, and the Von Hippel Lecture of
MRS, and two McDonald lectures 30 years apart of the Canadian Metallurgical
Society.

Honoring John Cahn on being named the recipient of
the Franklin Institute's 2002 Bower Award and Price for Achievement in
Science
Date: Wednesday, March 5, 2003
Location: San Diego Marriott Hotel & Marina Marina Ballroom D
Time: 12:00 PM–2:00 PM
Featuring a presentation by Dr. Cahn of his award lecture: “Revolutions
at the Crossroads--Interdisciplinary Opportunities For Making Scientific
Advances ”
 Presented
by:
John W. Cahn
About the topic:
When ideas from one field are tested in a quite different context, success
enlarges the idea and leads to consilience; whereas failure leads to creation
of new paradigms or even to scientific revolutions. Materials science,
a recently created “interdisciplinary discipline,” is full
of such idea transfers at the crossroads between its component disciplines.
A range of examples are traced from their long pre-science history in
ancient craft knowledge, ancient philosophy, and medieval scholarship,
and finally to their disparate and often unreconciled modern roots in
physics, chemistry, crystallography, mathematics, the materials disciplines
of metallurgy, ceramics and polymers, and engineering.
Luncheon tickets are $30 and may be purchased at the TMS Conference Registration
Desk. Tickets will NOT be sold at the door.
