Forbidden prize

Dan Shechtman of Technion - Israel Institute of Technology, in Haifa, Israel, is the recipient of the 2011 Nobel Prize for Chemistry for his discovery of quasicrystals. Shechtman's discovery on morning of 8 April 1982 of crystalline solids that seemed to break the rules about periodicity and symmetry essentially overturned what scientists consider to be the definition of crystalline. Although the finding was very controversial and it took many years for Shechtman to convince mainstream science of the validity of his findings. Today, it is well recognised that symmetry-forbidden crystalline materials exist and researchers are beginning to exploit them in understanding the strengths and weakness of steel, for instance.
