Isaac Newton, who'd be 370 years old this Christmas Day. 

         "I can calculate the motion of heavenly bodies, but not the madness of people."  Isaac Newton

So. An all too appropriate quotation for us here in this bittersweet season of the year, from this genius, who knew plenty of wonder and sorrow in his 17th century world and did his best to explain it.

Be merry, m'dears.
