—WALTER S. TEVIS
In a cozy study lit by a crackling fire, a weary high‑school physics teacher finds his routine interrupted by his eccentric colleague, Farnsworth. The scientist arrives with a strange, palm‑sized box and a gray sphere that defies the ordinary laws of motion, bouncing higher with each rebound. As the ball races around the room, gaining speed and even turning cold, the teacher is drawn into a baffling demonstration that hints at a revolutionary way to turn heat into motion.
The scene sets the tone for a witty, low‑key adventure where curiosity clashes with skepticism. Farnsworth’s quirky inventions and the narrator’s dry humor create a lively laboratory playground, inviting listeners to wonder what hidden principles might be at work. The story promises more brilliant experiments and unexpected twists, all while exploring the playful edge between science and imagination.

Best known for writing The Queen’s Gambit, The Hustler, and The Man Who Fell to Earth, he brought quiet intensity to stories about obsession, talent, and survival. His novels moved easily between pool halls, chessboards, and science-fiction landscapes, yet they all share a sharp eye for lonely, driven people.
