Pataphysics is the science of exceptions: this book shares the science in the form of 101 words. Pataphysics is also the "science of imaginary solutions," a science--according to Père Ubu--"that was invented in order to satisfy a need that was generally already felt." In short, "Science." Following in the footsteps of Alfred Jarry (1873-1907), the College of 'Pataphysics now cultivates the Science. These 101 entries outline the organization (Vice-Curator, Satrap, Order of the Grand Gidouille), its key concepts (Clinamen, Beatitude, Zimzum), and its relationships with ideas such as the Serious, the Humorous, and Desertion. These keywords also reveal the pataphysical brilliance of figures such as Dr. Faustroll, Raymond Queneau and Fernando Arrabal.
