The Nobel Prize in Physics 2017






The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2017 with one half to
Rainer Weiss

LIGO/VIRGO Collaboration
and the other half jointly to
Barry C. Barish

LIGO/VIRGO Collaboration
and
Kip S. Thorne

LIGO/VIRGO Collaboration
"for decisive contributions to the LIGO detector and the observation of gravitational waves"


 

Gravitational waves finally captured

On 14 September 2015, the universe’s gravitational waves were observed for the very first time. The waves, which were predicted by Albert Einstein a hundred years ago, came from a collision between two black holes. It took 1.3 billion years for the waves to arrive at the LIGO detector in the USA.
The signal was extremely weak when it reached Earth, but is already promising a revolution in astrophysics. Gravitational waves are an entirely new way of observing the most violent events in space and testing the limits of our knowledge.
LIGO, the Laser Interferometer Gravitational-Wave Observatory, is a collaborative project with over one thousand researchers from more than twenty countries. Together, they have realised a vision that is almost fifty years old. The 2017 Nobel Laureates have, with their enthusiasm and determination, each been invaluable to the success of LIGO. Pioneers Rainer Weiss and Kip S. Thorne, together with Barry C. Barish, the scientist and leader who brought the project to completion, ensured that four decades of effort led to gravitational waves finally being observed.
In the mid-1970s, Rainer Weiss had already analysed possible sources of background noise that would disturb measurements, and had also designed a detector, a laser-based interferometer, which would overcome this noise. Early on, both Kip Thorne and Rainer Weiss were firmly convinced that gravitational waves could be detected and bring about a revolution in our knowledge of the universe.
Gravitational waves spread at the speed of light, filling the universe, as Albert Einstein described in his general theory of relativity. They are always created when a mass accelerates, like when an ice-skater pirouettes or a pair of black holes rotate around each other. Einstein was convinced it would never be possible to measure them. The LIGO project’s achievement was using a pair of gigantic laser interferometers to measure a change thousands of times smaller than an atomic nucleus, as the gravitational wave passed the Earth.
So far all sorts of electromagnetic radiation and particles, such as cosmic rays or neutrinos, have been used to explore the universe. However, gravitational waves are direct testimony to disruptions in spacetime itself. This is something completely new and different, opening up unseen worlds. A wealth of discoveries awaits those who succeed in capturing the waves and interpreting their message.

HDFC Bank Scholarships 2017

 

HDFC Bank Scholarships 2017

'ECSS'- Educational Crisis Scholarship Support


OVERVIEW
HDFC Bank believes that the benefits of economic growth need to flow to all sections of society. Although not a panacea, education would be one of the main interventions that would lead to the overall economic and social development of the society. With the aim of empowering individuals who are economically and socially disadvantaged, the bank has initiated various projects in the field of education and livelihood training. 'Educational Crisis Scholarship Support' (ECSS) programme is envisaged to provide interim support for children facing a personal/economic exigency.

ABOUT ECSS
Economic hardship or a crisis in the family sometimes has a direct impact on the education of children, often resulting in the child dropping out of school/college/university. ECSS has been conceptualized to provide assistance to these students, to tide over a difficult situation/Personal/Family Crisis without adverse impact on their education.

THE SCHOLARSHIP
ECSS aims to cover students from recognized Private or Government aided schools between standards 6 and 12 and students studying in undergraduate and post-graduate courses (full-time/part-time degree/diploma/ courses) who due to personal/family crises are unable to continue bearing the cost of education and are at risk of dropping out of school/college/university. This situation would be defined as bereavement/death/ terminal illness/permanent disability and loss of job of the breadwinner due to accident or any such extreme circumstances that have put a strain on the family resources. The Scholarship will cover the total annual School Fee upto a maximum of Rs.10,000/- and College/University Fee upto a maximum of Rs.25,000/- of the selected candidates.

Last Date: 15th August , 2017
