The greatest challenge in fundamental physics attempts to reconcile quantum mechanics and general relativity in a theory of “quantum gravity.” The project suggests a profound revision of the notions of space, time and matter. It has become a key topic of debate and collaboration between physicists and philosophers. This volume collects classic and original contributions from leading experts in both fields for a provocative discussion of the issues. It

Over the course of the next fifty years, there will be a shift in the quest for sustainable energy, including a major change in transportation from internal combustion engines burning petroleum-derived fuels to newer technology engines using new transportation fuels. Alternative Energy Reources examines our options for energy sources with a focus on hydrogen as a large-scale, secondary energy vector parallel to electricity.

In addressing this “hard problem” of consciousness, we face a central human challenge: what do we really know and how do we know it? Tentative answers in this book follow from a synthesis of profound ideas, borrowed from philosophy, religion, politics, economics, neuroscience, physics, mathematics, and cosmology, the knowledge structures supporting our meager grasps of reality.
