Niels Bohr’s towering role in the history of physics can be difficult to appreciate. Robert P Crease explains why Man of integrity In his book Niels Bohr’s Times, the physicist Abraham Pais captures a ...

In a series of breakthrough papers, theoretical physicists have come tantalizingly close to resolving the black hole information paradox that has entranced and bedeviled them for nearly 50 years.

The main purpose of this chapter is to document the earlier statement that funding for all scientific research has substantially increased over the past decade. The bulk of the data were taken from ...
