Asymptotic Safety in Quantum Gravity and Diffeomorphic Non
... The discontinuity of the metric due to the behavior of the areal-radial function ρ(r = 0+ ; M ) = 2GM , ρ(r = 0) = 0, can effectively be interpreted as saying that the “point” mass has a finite area but zero volume [11]. It is generally believed that any quantum theory of gravity should have a gener ...

Bohr–Einstein debates
The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. Their debates are remembered because of their importance to the philosophy of science. An account of the debates was written by Bohr in an article titled ""Discussions with Einsteinon Epistemological Problems in Atomic Physics"". Despite their differences of opinion regarding quantum mechanics, Bohr and Einstein had a mutual admiration that was to last the rest of their lives.The debates represent one of the highest points of scientific research in the first half of the twentieth century because it called attention to an element of quantum theory, quantum non-locality, which is absolutely central to our modern understanding of the physical world. The consensus view of professional physicists has been that Bohr proved victorious, and definitively established the fundamental probabilistic character of quantum measurement.
