The Infinite Hotel

Jeffrey J. Wanko 

March 2009, Volume 102, Issue 7, Page 498

Abstract:
The short story “Welcome to the Hotel Infinity” uses the analogy of a hotel with an infinite number of rooms to help explain the concept of the cardinality of different infinities. This article provides a historical context for the debate between George Cantor and Leopold Kronecker (who are characterized in the short story) and it describes the author’s use of this history and short story in teaching difficult concepts about infinity.
