Assassin's Creed, Ezio Auditore +/ Leonardo da Vinci, TIL Leonardo da Vinci wrote “all the branches of a tree at every stage of its height when put together are equal in thickness to the trunk”. In 2011 Christophe Eloy investigated and found that trees which followed Leonardo's rule would be the best at resisting wind-induced fracture. (Ezio is so proud of his nerd bff)
