Gravity And me

From beloved and best-selling author Parker J. Palmer (Let Your Life Speak, The Courage to Teach, Healing the Heart of Democracy) comes a brave and beautiful book of reflections on eight decades of life and work. Reframing aging as "a passage of discovery and engagement", Palmer says, "Old is just another word for nothing left to lose, a time to take bigger risks on behalf of the common good."

Beyond Einstein’s Gravity is a graduate level introduction to extended theories of gravity and cosmology, including variational principles, the weak-field limit, gravitational waves, mathematical tools, exact solutions, as well as cosmological and astrophysical applications. The book provides a critical overview of the research in this area and unifies the existing literature using a consistent notation. Although the results apply in principle to all alternative gravities, a special emphasis is on scalar-tensor and f(R) theories.

One of the earliest bands to bring truly inventive ideas and energy to traditional American fiddle music, The Horse Flies have created a unique sound that remains fresh, powerful and captivating. Artful original songs, a wild groove-oriented approach to fiddle music, esteemed instrumental skills, and emotive singing come together as old-time fiddle music meets alternative rock, minimalism, modern songwriting and world percussion.

This comprehensive textbook is devoted to classical and quantum cosmology, with particular emphasis on modern approaches to quantum gravity and string theory and on their observational imprint. It covers major challenges in theoretical physics such as the big bang and the cosmological constant problem. An extensive review of standard cosmology, the cosmic microwave background, inflation and dark energy sets the scene for the phenomenological application of all the main quantum-gravity and string-theory models of cosmology.
