Contributions of Prof . James R . Melcher to engineering education

This paper reviews the teaching and research career of the late Professor James R. Melcher. It describes his approach to the teaching of electric and magnetic fields bolstered by the lecture demonstrations he had developed. He is considered the founder of the modern day field of electrohydrodynamics. His undergraduate courses, reinforced by educational films which are briefly described, gave st...

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...
