Topic : QGP – A New State of Matter
Type : Informative
Venue : Physics Gallery, Physics, GU
Date : Friday, 7 November, 2014
Time : 02:30 PM onwards

About the talk

One of the prime objectives of heavy ion collision experiments at relativistic energies is to create and study a new state of matter called quark gluon plasma believed to be existed at the early stage of the universe. A number of experiments are being carried out at RHIC, LHC and other relativistic heavy ion accelerator facilities to realize QGP. To be a part of these mega experiments, the Nuclear and Radiation Physics Research Laboratory of Dept. of Physics, GU has been collaborating with the ongoing LHC-ALICE experiment of CERN, Switzerland and future FAIR-CBM experiment of GSI, Germany. In this talk an attempt will be made to discuss what QGP is, how QGP could be produced, what the signatures of QGP are, and how the new state of matter is realized. An attempt will also be made to narrate GU activities related to ALICE and CBM experiments.

Dr Bhattacharjee is currently a professor in the Physics Department GU. He obtained his PhD from this university in nuclear physics.

11th P C Mahanta Memorial Lecture

Prof P C Mahanta was the founder head of the department of this department, who has given a definite shape to this institution. A PhD from Imperial College, London, he was a top-rated physicist of that time, working mainly on material science.

Born in the year 1911 in Bajali, Assam, Prof Mahanta was a visionary from the beginning. After completing his graduation from Cotton College, and masters from University of Calcutta, he joined Cotton College as a Lecturer in 1941. In 1948, he went to the UK to do his PhD from Imperial College, London, where he also earned a diploma from Imperial. On his return, he once again joined Cotton College before coming to Gauhati University as the founder Head of the Department of the newly founded Physics Department, in 1955, and remained till his superannuation.

Every year the Department organises this memorial lecture in the memory and honour of Prof Mahanta and remembers his invaluable contribution. Many famous scientists have graced this occasion in the past, which includes Sir (Prof) Arnold Whittaker Wolfendale, FRS and Astronomer Royal, UK, the famous Astrophysicist, Prof Jayant Vishnu Narlikar, and Prof Yash Pal, former Chairman of UGC. This year, we have dedicated the Memorial Lecture to the International Year of Crystallography, which is being celebrated worldwide, this year.

In this year, the 11th Memorial Lecture was delivered on Thursday, 13 November, 2014, by Molecular Biophysicist Prof M R N Murthy from Indian Institute of Science (IISc), Bangalore.

2014 Memorial Lecture :

Speaker : Prof M R N Murthy, IISc, Bangalore, India
Topic : Celebration of the International Year of Crystallography : A Personal Saga
Venue : Physics Gallery, Physics, GU
Date : Thursday, 13 November, 2014

Abstract

As a part of the celebration of the International year of crystallography and in recognition of great strides that have recently been made in structural biology, I will present historical perspectives and recent experimental and theoretical advances in X-ray diffraction studies on biological macromolecules. I will illustrate the technology and the excitement of research in this area with our work on the structure and assembly of Sesbania mosaic virus as an example.

Biography of Prof M R N Murthy

Prof Mathur Ramabhadra Shastry Narasimha Murthy was born in the small village of Mathur situated in the Shimoga District of Karnataka State. Because of his background, Murthy has intimate knowledge of Indian rural traditions and customs. Murthy, along with Professor M. Vijayan, established X-ray diffraction facility at the Molecular Biophysics Unit, which served as the national nucleus for crystallographic work in the initial decade of such structural work in India. Also in the 1980s and early 1990s, computational facilities available at the Indian Institute of Science were inadequate for even protein crystallography and successful execution of structural studies of viruses was unimaginable. Murthy developed methods for the structure determination and analyses of viruses that were computationally efficient and less demanding of resources, writing several programs and adopting a number of other available programs to smaller computing machines.

His success in these endeavours is reflected in the successful conclusion of several structural studies on virus particles, which are the only such studies performed in the twentieth century in the third world. Murthy has shown deep commitment to Science education in the state of Karnataka of India. This interest has been facilitated by his intimate knowledge of the state language, Kannada and his ability to express ideas of Science with ease. He has actively participated in the activities of Karnataka Rajya Vigyana Parishad (an autonomous organization with the goal of promoting science education), Bangalore Association for Science Education (functioning from the Nehru Planetarium, Bangalore), extension lecture program of the Indian Institute of Science, supported by the University Grants Commission, New Delhi and Karnataka State Council for Science and Technology.

He frequently writes articles on scientific ideas and discoveries in the local language. Kannada Pusthaka Pradhikara (a publishing body of the Karnataka Government) has published a popular book on Biotechnology written by him in Kannada.

Overview
The Gauhati University Observatory, popularly known as the GUO is one of the largest astronomical observatory in the Northeastern India, operated by a university. It is operated by the Physics Department of Gauhati University and located on a hilltop inside the university campus. At present, this observatory houses 5 telescopes, of which the largest (in terms of the diameter of the objective mirror of the telescope) telescope of 16-inch diameter (Meade ACF) is the recent addition. This telescope is permanently mounted inside the observation dome and is completely controlled by the onboard electronics and computers. The newest acquisition to the GUO is a fully automatic, GPS controlled, 9-inch (Celestron) telescope with external battery bank for outdoor operation. While the 16-inch ACF will be completely devoted to research along with some of the very sophisticated scientific instruments, the 9-inch telescope is devoted to day-to-day observation, student training, and public viewing. This telescope is a portable one and can be setup for astronomical observation within a few minutes with the help of its GPS controller. It is mounted on an equatorial tripod and housed under motorised sliding-roof fibre glass observation dome.

Background
The GUO was set up in the early eighties by Prof Hiralal Duorah, then a professor of astrophysics, who has later become the Vice Chancellor of this university. It was his initiative that this observatory has come to exist. The observatory was started with the only telescope available at that time in the Physics Department, a 6-inch reflecting, German made (Carl Zeiss) telescope of the fifties. Several astronomical observations were made with this telescope and two students have gone to receive their PhD degrees on astronomy, with observation initiated with this telescope. In the nineties, a new computerised telescope, a 12-inch Meade 12-XP was commissioned. This was a completely state-of-the-art telescope by the standards of that time and is still in operation.
In recent times, several sophisticated scientific instruments including a photoelectric photometer, high definition CCD camera, and a spectrograph were procured. In 2008, with additional grant from the state government, the University has decided to upgrade the facilities of the GUO by providing the necessary funds. As a result, a 16-inch automatic telescope was procured. This telescope was custom made by the manufacturing company, Meade Corp, USA for the GUO and has already been installed in the GUO. A 9-inch telescope is installed in a newly constructed, sliding roof, motorized, fibre glass dome in the observatory. This new observation dome is conceptualized and designed by Madhurjya P Bora, In-Charge of the observatory, which is later fabricated by a specialized firm. When needed, the roof of this observation dome can be completely removed (with the help of a remote controlled motorized system) to get the maximum exposure of the night sky by the telescope.

Examination on Programming Lab (2nd Sem)

The practical examination (Marks : 20) on Programming Lab is held alongside the practical internal examination (during May-June) of 2nd Semester.
This examination is held online in the Computer Lab. The questions are designed to test the programming concept (not numerical analysis) related the FORTRAN language.

Use of Computer Lab

As you know, in our continuing effort to providing better facilities to our students, faculties, and staffs, we have already made the computer lab open for 24 hours, 365 days a year. Any permanent member of the department (members of the faculty, staff, and research scholars) is provided fingerprint authentication so that he/she can use the lab at any time during the day.
The MSc students can use the lab at any time during the day, however, they are not provided the authentication. They need to request somebody, who can provide authentication, in order to enter the lab. This is done, officially by Mr Sahadev (lab attendant), whom you can find during office hours. Now we have extended this time till 7:30 PM in the evening, beyond which they must be accompanied by a person, who can authenticate.

However, if an MSc student needs to use the lab beyond the designated time, they can always request Dr M P Bora (in-charge) for permission.

Hereby, it is being notified about this to all concerned students and staff.

Please DO NOT switch off any computer or power supply. If you are the last person to come out of the lab, please switch off all lights, fans, and A/Cs.
