Synopsis
|
Published April 20, 2009 Finding a quantum theory of gravity remains one of the great unsolved problems in modern physics. Two papers present a quantum gravity theory that, while making different assumptions than general relativity, still reproduces Einstein’s theory in certain limits. |

Synopsis

Published July 28, 2008 A “simple” closed-form Hamiltonian for a relativistic system of n gravitating particles, which depends only on the particles’ momenta and coordinates, is developed. |

Physics 1, 3 (2008) – Published July 14, 2008 The longitudinal ringing mode of a metal bar resonator weighing approximately one metric ton has been cooled to submillikelvin temperatures with the use of active amplifier feedback. Further improvements may allow researchers to approach the quantum limit for cooling macroscopic objects. |
