Tom Gauld’s delightful cartoon featuring gingerbread men raises an interesting possibility. If what one gingerbread man says is true, namely that you can “run, run as fast as you can! You can’t catch me…”, then the only conclusion is that gingerbread men are able to travel at the speed of light. From this, you can conclude that they must have no mass. So on this basis, they appear to be the perfect treat for those on a diet (7 September, p 47).
