<div>A little research reveals that the prize went to Willis Lamb, whose ovinely named Lamb shift is related to the Dirac equation!</div>

<div>Ha! So Dirac relates to the tera' DI'raq in two different ways!<br/>
<br/>
By the way, I've figured out two more puns from the novel. 'ughDuq gharghmey are "ugly duckling larvae", and Su'wan ghewmey are "swan birds", because like the protagonist of the Hans Christian Andersen story, a lepidopteran starts its life as an allegedly ugly worm-like caterpillar, and then grows up to be a beautiful butterfly!</div>
