7.21




(Cool Treats Dies, Summer Sampler)


(New Beginnings 2)

Over 500 years ago, Leonardo da Vinci made an interesting observation about trees. He concluded that the total thickness of a tree’s branches is equal to the total thickness of the tree trunk. Trees across many species obey this rule. Explanations involve hydrological and structural theories.
