Don’t get me wrong, Stephen Hawking is a mathematical genius, but it takes more than that to estrange him from everyone. When writing a brief history, his editor warned him that for every equation included in his book, the readership would be cut in half. Imagine the imagination it requires to condense the most complex astrophysics and mathematical theory into something simple, enjoyable (yes enjoyable!), and comprehensible for ten million readers. He used only one equation.
