Branching structures exist throughout nature — in trees, of course, but also in leaves, veins and arteries. Mitchell Newberry, a research assistant professor of biology at the University of New Mexico, writes about Dutch artist Piet Mondrian's tree paintings, which evolved from realistic depictions in context, to overlapping lines in shades of gray. “Gray Tree” uses only curved lines of various thickness superimposed on top of one another at seemingly random angles. Yet the image is unmistakably a tree," writes Newberry for @TheConversationUS. "How did Mondrian convey the sense of a tree with so little? The science of trees may offer some clues."
