Mike Okuda, one of Star Trek's technical directors, the originator of the Okudagram, and the co-author of several Star Trek books, including the Star Trek: The Next Generation Technical Manual and the world-famous Star Trek Encyclopedia, answered the telephone to find someone on the other end asking "How does the Heisenberg compensator work?" to which he answered "Very well, thank you," and put the phone down, because the Heisenberg compensator is a device used in the transporter system to compensate for the Heisenberg Uncertainty Principle (that you cannot know a particle's position and velocity at the same time) which would otherwise render transporters theoretically impossible (as an afterthought, Zulu One refers the reader to amazingly long sentences).
