Lancaster: American Physical Society, 1967. 1st Edition. FIRST EDITION of Bryce DeWitt’s first paper on quantum gravity, including the introduction of both the Wheeler-DeWitt equation and canonical quantum gravity. Quantum gravity attempts to unify quantum mechanics (which describes the behavior of electromagnetism, the weak interaction and the strong interaction) with general relativity (the theory of gravity). In this work, DeWitt, known as the father of quantum gravity, formed important calculations on quantum gravity highly controversial and important to modern theoretical physics. The Wheeler-DeWitt “equation expresses the expectation that the total energy of a closed universe vanishes” (Liebscher, Cosmology, 269). It is a “cosmic Schrodinger equation” that describes the whole universe - both atoms and galaxies - in a unified manner. Although controversial, the equation does in fact unify deep properties of both quantum theory and general relativity. “The Wheeler–DeWitt equation is a functional differential equation on the space of three dimensional spatial metrics . It is ill defined in the general case, but very important in theoretical physics, especially in quantum gravity. The equation has the form of an operator acting on a wave functional, the functional reduces to a function in cosmology. Contrary to the general case, the Wheeler–DeWitt equation is well defined in mini-superspaces like the configuration space of cosmological theories” (Wikipedia). Item #366
