From floods to earthquakes to revolutions, 2011 has come and gone at a high price. The last year has seen a lot of changes both politically and economically, and as we move into 2012 there is a lot of rebuilding to be done. In many ways 2011 was the end of an era. No more space shuttle launches, no more Oprah, no more bin Laden, and no more Steve Jobs. In spite of all that, however, it was also a year of new beginnings as entire nations found their independence, a royal wedding captivated the world, and revolutions brought freedom to millions. These were the most defining moments of 2011, and they will not be easily forgotten.
