Incidentally, there's a really subtle Dyson pun in the title of this post. Like super-subtle. Ultra-subtle. Harder to find than the Higgs Boson. So tiny it's subject to quantum weirdness. It's like a pun particle (known to scientists as the punon), subject to Humorberg's Uncertainty Principle ("You can either know where a pun particle is in a joke, or you can know how funny it is, but you cannot know both").
