Dan Shechtman Wins 2011 Nobel Prize in Chemistry - Israel Celebrates Its10th Nobel Laureate

In 1982, Dan Shechtman discovered the impossible, till then, quasiperiodic crystal structure characterized by a fivefold symmetry in contrast to the then prevailing classical crystallographic restriction theorem stating that a crystal can possess only two, three, four, and six-fold rotational symmetries. For this discovery Dan Shechtman was awarded the 2011 Nobel Prize in Chemistry.

Apple Remembering Steve Jobs
Steve Jobs

Apple has lost a visionary and creative genius, and the world has lost an amazing human being. Those of us who have been fortunate enough to know and work with Steve have lost a dear friend and an inspiring mentor. Steve leaves behind a company that only he could have built, and his spirit will forever be the foundation of Apple.
