Da Vinci’s Rule of the Trees

Over 500 years ago, Leonardo da Vinci made an interesting observation about trees. He that the total thickness of a tree’s branches at a certain height almost always equals the total thickness of the tree trunk. In other words, as the tree splits into , the cross section of the branches remains equal to the cross section of the trunk. This observation holds true for almost all trees. When trees begin , they make exact copies of themselves. Scientists believe that there are two reasons for this law of nature. Firstly, this design is ideal for transporting sap through a tree. , this structure makes a tree more resistant to wind. Artists use Leonardo da Vinci’s rule of nature to design real-looking trees.
