 In Chapter one, what is the significance of describing Mr. Taylor as not having aged much?
Eddie Taylor would like to have finished it, but the bar of morning sunlight poking in under the window shade pried his eyes open. Still, one clue is as good as another when it comes to hunting uranium ore, I guess. In fact, anything having to do with atomic science excited him. You couldn’t have a father who was head of the atomic-science department at Oceanview College without picking up a little knowledge along the way. When carefully controlled, the radiation stored up in such isotopes was used in many beneficial ways. One reason for asking that particular question was to keep from prying deeper into the subject of the radioisotope. At the speed atomic science is moving today, we simply can’t afford to waste time.
 It provides a contrast for later in the story, when Mr. Taylor is described as looking aged and wary after the isotope is stolen.
 It provides the notion that Mr. Taylor is a fun, understanding, and competent professor.  It provides the notion that despite Mr. Taylor’s dangerous job, the radioactivity hasn’t aged him a day.  It provides a contrast for later in the story, when Mr. Taylor is described as looking aged and wary after the isotope is stolen.  It provides a contrast against Mr. Ross, who is described as older and balding.
