High Quality Content by WIKIPEDIA articles! The Schrödinger's Cat Trilogy is a trilogy of novels by Robert Anton Wilson consisting of The Universe Next Door, The Trick Top Hat, and The Homing Pigeons, each illustrating a different interpretation of quantum physics. Wilson is also co-author of The Illuminatus! Trilogy, and Schrödinger's Cat is a sequel of sorts, re-using several of the same characters and carrying on many of the themes of the earlier work. The one-volume edition currently in print is significantly shorter than the original three-volume edition. This is not a difference in print size or removal of redundant "recaps"; it is missing a noticeable amount of material, including many entire chapters.
