Einstein's general theory of relativity  currently our best theory of gravity  is important not only to specialists, but to a much wider group of physicists. This short textbook on general relativity and gravitation offers students glimpses of the vast landscape of science connected to general relativity. It incorporates some of the latest research in the field. The book is aimed at readers with a broad range of interests in physics, from cosmology, to gravitational radiation, to high energy physics, to condensed matter theory. The pedagogical approach is "physics first": readers move very quickly to the calculation of observational predictions, and only return to the mathematical foundations after the physics is established. In addition to the "standard" topics covered by most introductory textbooks, it contains short introductions to more advanced topics: for instance, why field equations are second order, how to treat gravitational energy, and what is required for a Hamiltonian formulation of general relativity. A concluding chapter discusses directions for further study, from mathematical relativity, to experimental tests, to quantum gravity.
This is an introductory text, but it has also been written as a jumpingoff point for readers who plan to study more specialized topics.

Adventures in Problem Solving
What is "problem solving"? The grat mathematican David Hilberd said that, in essence, probles are the life blood of mathematics, and Paul Halmos added a rider: that the complementary activity  theory building  provides the soul of the subject. ...   Economics for Policy Makers: A Guide for NonEconomists
Certain key economic decisions taken by organizations and indeed countries are often not made by economists but by businessmen, trade unionists, politicians and policymakers. Those who employ people, those who represent workers, those who make laws and those who elect them need economics but may have little time or desire to study...
