who were the greatest scientist/poets?

My votes go to Oppenheimer, who read the Bhagavad Gita in its original Sanskrit, and opened the Atomic Age with deep poetic symbolism (Trinity from John Dunne's Batter my heart, three-person'd God, for example.)

and

Omar Khayyam who defined the Persian calendar for a millennium and linked algebra and geometry together in fundamental ways, while writing enough quatrains to form the Rubáiyát.

Very open if others have suggestions!
