It took William Harvey until 1628 to propose the theory of blood circulation.
Yesterday, budding scientist Luciya placed a the hollow end of a water glass on the inside of her elbow and laid her ear on the other end. "I can hear my blood smushing and whushing in there," she announced.
She's not even five yet.

And William Harvey started trying to figure it out in 1514, congratulations! Next stop MacArthur Grant.
