For more than three centuries botanists and mathematicians have marveled at the complex and beautiful spiral patterns that form as plants develop. As they generate leaves around a stem, or seeds or flowers in a blossom, plants as diverse as broccoli, pinecones, artichokes and water lilies create intricate spirals that follow a well-known mathematical sequence of numbers.Link Discuss (Thanks, Michael!)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
