Flying brooms, magical creatures and spells are what make the world of Harry Potter so extraordinary. Of course, these things don't exist in reality - or do they? Is it possible by biological coincidence that a three-headed guard dog like Fluffy exists? Could the existence of gravitational fields explain why the Nimbus 2000 can fly? And is a griffin nothing more than the now-extinct dinosaur Protoceratops? The science behind Harry Potter looks at the mysterious phenomena around Hogwarts and explains if and how they could also occur in our Muggle world. An educational and entertaining book full of surprises.
