| Abstract | Summary form only given. Scientists from 16 countries are building the largest ever Observatory for the Highest Energy Cosmic Particles. In the Argentina pampas, 1,600 water Cherenkov detectors will cover an area of 3,000 square kilometers overlooked by four fluorescence telescopes. The Cherenkov detectors are placed in a 1.5-kilometer triangular grid, powered by solar panels, timed by GPS's, and communicating via radio antennas. At the highest energies, one cosmic ray particle generates a shower that triggers dozens of detectors within microseconds as the shower reaches the ground. In dark moonless nights, the fluorescence telescopes observe the same showers through the ultraviolet emission of nitrogen molecules in the air excited by shower particles. The fluorescence telescopes are sensitive to the faint UV emission from tens of miles away. Together, the fluorescence telescopes and ground Cherenkov detectors form the most powerful observatory to ever study the highest energy cosmic ray showers. The goal of the Pierre Auger Observatory is to unveil the mysterious origin of particles with energies a billion times larger than present terrestrial accelerators can reach. During deployment, the Observatory has already produced intriguing results during construction. We will discuss the astrophysical and physical challenges of unveiling this high-energy mystery |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
