A point particle moving in a central force field has three degrees of freedom, we need three coordinates to specify the location of the particle. The Ea ...

How far are we from the quantum theory of gravity?
... theory. When a path integral is involved it should be fully defined in terms of a well defined measure, or else expressed as a discrete summation. This led in each case to two lists, the first of results, the second of conjectures and open issues. These are summarized in Table 1, which indicates th ...
