of the gravitational field
Fundamental equations in the general theory of relativity. They connect the metric tensor of the
space-time continuum, which describes the gravitational field, and the physical characteristics of
different forms of matter, described by means of the energy-momentum tensor:

NIIST scientist bags award for physical sciences
His work leads to the development of superior light harvesting devices
A. Ajayaghosh, CSIR-Outstanding Scientist at the National Institute for Interdisciplinary Science and Technology (CSIR-NIIST) here, who bagged the Infosys Prize 2012 in Physical Sciences, announced in Bangalore on Friday, has been recognised for his work that has led to the design and synthesis of organogels (pi-gels), a new class of nanomaterials with great potential for photonic and electronic applications.
According to the jury citation, Prof. Ajayaghosh has demonstrated that these self-assembled nanomaterials can be used to control the electronic energy transfer processes, paving the way for the development of superior light harvesting devices. Prof. Ajayaghosh was the first investigator to make functional phenylenevinylene organogels from designed building blocks. He is a leader in this exciting new area of materials chemistry.
The prize includes a gold medallion, a citation certificate, and prize money of Rs.50 lakh.
When contacted, Prof. Ajayaghosh said, “As a Keralite, and as someone whose entire education has been within the home State, I feel proud to have been selected for this award. I owe this honour to my group of students and collaborators. I feel happy that science in India is getting due recognition.”
He hoped the award would encourage more youngsters in Kerala to take to science as a career.
His message to young scientists was, “If you are ready to work, there is nothing to stop you”. The secret of being a successful scientist, according to him, is a passion for science, the commitment to work and the patience to wait.
Prof. Ajayaghosh obtained his Master’s degree in Science (1984) from Kerala University and a Ph.D. (1988) from Calicut University. He joined the Regional Research Laboratory, CSIR (presently CSIR-NIIST), as a scientist in 1988. He was the Alexander von Humboldt Fellow at the Max Plank Institute for Strahlen Chemie, Germany (1994-96).
He has received several awards such as the Thomson Reuters Research Excellence Award (2009), the Outstanding Researcher Award of the Department of Atomic Energy (DAE) (2009), the Ramanna Fellowship of the Department of Science and Technology, India (DST) (2007) and the Shanti Swarup Bhatnagar Prize for Chemical Sciences (2007).
He has published several articles, book chapters and filed patents in the areas of molecular self-assembly, molecular probes and fluorescent materials. He is a Fellow of all the three Science Academies of India, and is on the international advisory board of the journal, Chemistry-An Asian Journal .

Quantum physicists win 2012 Physics Nobel prize
Serge Haroche of France and American David Wineland opened the door to new experiments in quantum physics by showing how to observe individual quantum particles while preserving their quantum properties.
A quantum particle is one that is isolated from everything else. In this situation, an atom or electron or photon takes on strange properties. It can be in two places at once, for example. It behaves in some ways like a wave. But these properties are instantly changed when it interacts with something else, such as when somebody observes it.
Working separately, the two scientists, both 68, developed "ingenious laboratory methods" that allowed them to manage and measure and control fragile quantum states, the Royal Swedish Academy of Sciences said.
"Their ground-breaking methods have enabled this field of research to take the very first steps towards building a new type of superfast computer based on quantum physics," the academysaid. "The research has also led to the construction of extremely precise clocks that could become the future basis for a new standard of time."
Haroche is a professor at the College de France and Ecole Normale Superieure in Paris. Wineland is a physicist at the National Institute of Standards and Technology, or NIST, and the University of Colorado in Boulder, Colorado. The two researchers use opposite approaches to examine, control and count quantum particles, the academy said. Wineland traps ions - electrically charged atoms - and measures them with light, while Haroche controls and measures photons, or light particles.
Haroche said he was out walking with his wife when he got the call from Nobel judges. "I was in the street and passing a bench so I was able to sit down," Haroche told a news conference inStockholm by phone. "It's very overwhelming." He said his work in the realm of quantum physics could ultimately lead to unimaginably fast computers.
ഭൌതിക ശാസ്ത്രത്തിനുള്ള നൊബെല് സെര്ജെയും വിന്ഫീല്ഡും പങ്കിട്ടു
