GUWAHATI, March 20 - The Department of Physics of Arya Vidyapeeth College commemorated 100 years of the �General Theory of Relativity� along with the celebration of the recent discovery of gravitational waves, through various activities.
It may be mentioned that the current Laser Interferometer Gravitational Observatory (LIGO) captured the signal of gravitational waves on September 14, 2015. The entire world got enthralled on February 11, 2016 when physicists announced the first direct detection of gravitational waves. These waves, which were produced by the collision of two super-massive black holes, are actually ripples in the fabric of space time, which was predicted by Einstein 100 years ago in 1916.
In the first phase of the series of programmes, Prof KD Krori, well-renowned physicist and former principal of Cotton College delivered an invited lecture titled �Gravitational waves � from Einstein to the present LIGO�.
Prof N Nimai Singh of Manipur University also gave an invited talk on this occasion on March 14, the birthday of Einstein.
As a continuation of this celebration, Dr Subir Sarkar, a faculty member of the Department of Physics of Arya Vidyapeeth College delivered a talk titled �Certain selected topics associated with Einstein�s life and work�. Rashidul Haque, research scholar, presented a talk on some aspects of the recently discovered gravitational waves and the LIGO, which detected the wave.
Other highlights of the event included a poster exhibition by students based on the life and work of Einstein and a talk by students on Einstein�s work. There were interactions between the speakers and the audience during each talk.
Dr Pijush Kanti Dhar, Associate Professor of the department and convener of the programme, while thanking the faculty members and students from different quarters for their big response, said that it reflected the enormous interest towards the recent epoch-making discovery of the gravitational waves and the growing inquisitiveness towards physics and discoveries associated with physics.
