Israeli Scientist Wins Nobel Prize for Chemistry
By KENNETH CHANG
Published: October 5, 2011
An Israeli scientist won this years Nobel Prize in Chemistry for discovering a material in which atoms were packed together in a well-defined pattern that never repeats.
Recent Nobel prizes have generally split credit for scientific advances among two or three people, but this years chemistry prize and accompanying 10 million Swedish kronor ($1.4 million) went to a single scientist: Daniel Shechtman, 70, a professor of materials science at Technion - Israel Institute of Technology.
The citation from the Royal Swedish Academy of Sciences states simply, for the discovery of quasicrystals.
Such regular but non-repeating patterns, defined by precise rules, have been known in mathematics since antiquity and are found in mosaics of medieval Islamic tiles, but it was thought impossible in the packing of atoms.
Dr. Shechtman discovered the same type of structure while studying a metal mix of aluminum and manganese. His notebook recorded the exact date: April 8, 1982.
Scientists believed that crystals in materials all contained repeating patterns, and Dr. Shechtman took years to convince others. During the announcement, the Nobel committee noted that one colleague said, Go away, Danny and that he was even asked to leave his research group.
Quasicrystals have since been found in many other materials, including a naturally occurring mineral from a Russian river.
