In addition, Mr. Paul became a Fellow of the Association of Surgeons of Great Britain, and a member of the council. He was a member and past president of the Moynihan Chiru...

f(R) Theories

Over the past decade, f(R) theories have been extensively studied as one of the simplest modifications to General Relativity. In this article we review various applications of f(R) theories to cosmology and gravity - such as inflation, dark energy, local gravity constraints, cosmological perturbations, and spherically symmetric solutions in weak and strong gravitational backgrounds. We present ...

f(R) Quantum Cosmology

We have quantized a flat cosmological model in the context of the metric f(R) models, using the causal Bohmian quantum theory. The equations are solved and then we have obtained how the quantum corrections influence the classical equations.

1. Laertes is about to stab Hamlet. Claudius, watching from the wings, desperately wants Laertes to stab Hamlet and has implanted a device in Laertes’ brain that, if activated, will force him to stab Hamlet. Claudius intends to activate the device if it appears that Laertes will change his mind at the last moment. Laertes, however, stabs Hamlet of his own accord and Claudius’s device is never a...
