Thinking along these lines will help prepare us for the day when we—or more likely, our distant descendents—will develop the machinery and cleverness… - Frank Wilczek

Particles that, like ⁴He, show constructive interference are said to be bosons—a shorthand term for "particles obeying Bose–Einstein statistics." …One way to recognize bosons is their tendency to imitate one each other. ...the presence of one boson increases the chance that another of its identical siblings will also appear in the same spot. There's an attraction between them. We will speak ...of an attractive identity force drawing together identical bosons. Lasers are a spectacular example...

If grand unified theories are correct, we ought to be able to derive the relative power of the strong, weak, and electromagnetic interactions at accessible energies from their presumed equality at much higher energies. When this is attempted, a wonderful result emerges. ...in the form first calculated by Howard Georgi, Helen Quinn, and Steven Weinberg ...The couplings of strong-interaction gluons decrease, those of the [weak interaction] W bosons stay roughly constant, and those of the [electromagnetic interaction] photons increase at short distances [or high energies]—so they all tend to converge, as desired.

Does Michael Jackson or Archie Bunker or the president of General Motors need to know about quantum mechanics? Of course not. You can live a full life without that. But if you don’t believe that the universe is understandable, then it leads to the notion that one idea is just as good as another. And that’s horrible.
