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.

Steve Jobs, father of the Macintosh PC, iPhone and iPad died this day (October 5, 2011)

Apple Remembering Steve Jobs
Steve Jobs
1955-2011


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.
