Marshall Zebatinsky is a talented nuclear physicist buried in a faceless government research team, just one more mind in an anonymous crowd. Desperate for recognition, he does the least “scientific” thing imaginable: he visits a dingy numerologist in a run-down storefront who claims to use a secret computer to tweak the probabilities of the future. The fix he suggests seems laughably small—change one letter of Zebatinsky’s name, from Z to S—but that tiny alteration echoes into places Marshall never intended, from security files to high-level briefing rooms.
While Marshall tries to convince himself he’s merely wasted fifty dollars, Security officers begin asking a simple question: why would a nuclear physicist change his name in that particular way? As they dig into foreign relatives, vanished Soviet scientists, and obscure gamma-ray research, a personal decision becomes part of a much larger Cold War puzzle. “S as in Zebatinsky” is a smart, quietly escalating science fiction tale about probability, paranoia, and how the smallest details can shape the fate of nations.
Isaac Asimov (1920–1992) was one of the towering figures of 20th-century science fiction, renowned for his Foundation series, his groundbreaking robot stories, and his talent for turning complex science into clear, engaging narrative. Trained as a biochemist, he combined a rigorous scientific mind with a love of logic puzzles, debates, and thought experiments.
Over the course of his career, Asimov wrote or edited hundreds of books and stories, helping to define the Golden Age of science fiction and influencing generations of writers, scientists, and fans. If you enjoy stories where ideas and human choices matter as much as gadgets and explosions, “S as in Zebatinsky” is Asimov in a wonderfully clever, low-key mode.
