Happy Birthday, Leonardo Da Vinci

553 years ago today, a genius was born. I used to know so little about this guy until I read the bestselling book Da Vinci Code. With all those hidden messages in his paintings, ingenious inventions scribbled in his notebook, and proofs of mathematical wonders like Fibonacci Sequence, I bet he is still smiling smugly in his grave, waiting for someone someday would match his brilliance.
