Waldo and Magic, Inc.

The book actually combines two of Heinlein's shorter works: the titular "Waldo" and "Magic, Inc." The first tells the story of a disabled genius who invents remote manipulation devices, while the second explores a world where magic is a regulated corporate industry. Both stories explore themes of technology, human potential, and the supernatural.

Yes, Heinlein popularized the term "waldo" in this 1950 novel to describe the mechanical remote manipulation gloves used by the main character. The term was so perfectly fitting that real-world engineers adopted it. Today, a "waldo" is the actual technical term used in engineering and robotics for a telemanipulator device.

The story follows Waldo Farthingwaite-Jones, a brilliant but physically frail inventor who lives in a zero-gravity space station because his muscles are too weak for Earth's gravity. He creates sophisticated robotic hands that he controls remotely, allowing him to interact with the physical world. Eventually, he discovers a mysterious energy source that challenges the known laws of physics.

Yes, this early Heinlein work is highly accessible and perfectly showcases his Golden Age sci-fi style before his later, more controversial novels. The stories are relatively self-contained, fast-paced, and highly imaginative. It is a great starting point for readers interested in his classic technological predictions.
