The Veins of a Leaf: Revealing Nature’s Mathematical System

 
“Nature is a great architect, and the vascular network – or veins – of a leaf are key to its structure. Mathematical physicists [Marcelo Magnasco and Eleni Katifori] at Rockefeller University  use fluorescent dye and time lapse photography to digitally study microscopic patterns within these vascular networks in order to better understand how nutrients flow through the leaf and into the plant’s cells.”
