I ndIa has grown by leaps and bounds in recent years and is emerging as a major world economic power. after lumbering along at a pace of about 4–5 percent GdP growth a year in the 1980s and the 1990s, the economy has surged in this decade, posting an average annual growth of 8.5 percent since 2005 (see Chart 1). The challenge now is to maintain this growth momentum and provide benefits as well ...

Neutron matter presents a unique system for chiral effective field theory because all many-body forces among neutrons are predicted to next-to-next-to-next-to-leading order (N(3)LO). We present the first complete N(3)LO calculation of the neutron matter energy. This includes the subleading three-nucleon forces for the first time and all leading four-nucleon forces. We find relatively large cont...

This paper provides a personal perspective on the rich discussions at the Bixby Forum. The size, rate of growth and age structure of the human population interact with many other key factors, from environmental change to governance. While the details of future interactions are sometimes difficult to predict, taken together they pose sombre threats to a socially and economically sustainable futu...
