Two-Day Symposium Honors Work of Prof. Daniel Shechtman
The Technion celebrated Distinguished Professor Daniel Shechtman's 70th birthday with a special two-day (January 12-13) symposium honoring his work, which opened up the field of quasicrystals as an area of study in crystallography, physics, chemistry and materials science.
"Symposium On Quasicrystals,” hosted by the Department of Materials Engineering, drew nearly two dozen scientists from international universities and centers including: Walter Steurer of the ETH in Zurich, Switzerland; M. de Boissieu of the CNRS in Grenoble, France and A. P. Tsai from Tohoku University in Japan. Lectures covered the esoteric: “Phason Modes in Quasicrystals,” as well as more accessible topics like “Quasicrystals Gifts to Mathematics.”
Prof. Shechtman, the Philip Tobias Professor of Materials Science, received his undergraduate degree and post-graduate degrees from the Technion, and joined the faculty in 1975. While on Sabbatical at Johns Hopkins University and working with the National Bureau of Standards, he discovered the quasicrystal – which appeared to have the same kind of order that was inherent in a crystal, but was also symmetrical in ways that were believed to be physically impossible for a crystalline substance. He was ridiculed by the scientific community for two years until his discovery gained traction.
“If you’re a scientist and believe in your results: fight for them,” he says. “Fight for the truth.”
Today, hundreds of materials are known to exist with the structure that Prof. Shechtman discovered, and every year, a number of national and international conferences are held on this subject.
Prof. Shechtman is a distinguished professor in the Technion’s Faculty of Materials Engineering, and at the University of Iowa in the United States. He has won many prizes including the Israel Prize, the Wolf Prize, the EMET Prize, and the Aminoff Prize of the Royal Swedish Academy of Sciences. He is a member of the Israel Academy of Sciences and the U.S. National Academy of Engineering.
Over 40 scientific books have been dedicated to quasiperiodic crystals, and in many other books, the chapters dealing with crystallography have been updated. In wake of the discovery and its proof, the International Society of Crystallographers gave has changed the basic definition of a crystal.
