So why would you want to give away £20 million – over $30 million – even if you had it? In the case of hedge fund superstar David Harding, part of the answer on why he has just made the biggest gift ever to the Cavendish Laboratory at Cambridge University was, he said, that it was a form of compensation for all the physicists his firm had “poached” from the world of science. He was only partly joking: his firm, Winton Capital Management, employs over 90 researchers with PhDs or other higher degrees in subjects ranging from extragalactic astrophysics to artificial intelligence.
