A REPORT ON
Science Academies’ 56th Refresher Course in Experimental Physics
The Science Academies’ 56th Refresher Course in Experimental Physics was held at Department of Physics, Panjab University, Chandigarh from Feb. 11 – Feb. 26, 2014. Twenty two participants attended the Course, Fifteen of them faculty members from different colleges of different parts of India and rest were the Ph.D. scholars who were interested in joining teaching profession. One participant has to drop out in the middle of the course due to health reasons. About 30 candidates applied for the course and 25 were selected. Three candidates dropped in the beginning as their college declined to give relieve them. List of participants is attached as Annexure-A. Prof. Arun K. Grover, Vice-Chancellor, Panjab University inaugurated the 56th Refresher Course. Prof. R. Srinivasan, Course Director; Prof. Manjit Kaur, Chairperson, Department of Physics; Prof. Navdeep Goyal, Dean Students Welfare; and Prof. D. Mehta, Course Coordinator; were present on the dais The function was attended by the participants of the refresher Course, faculty members of the Physics Department, and the research students. Mrs. Srinivasan was also present to grace the occasion. In his inaugural address, Prof. Arun K. Grover briefly talked about the efforts of Prof. R. Srinivasan in establishing low-temperature research facilities in India during his career. Prof. Grover also recollected his own scientific interactions with Prof. Srinivasan. Prof. Manjit Kaur gave brief account of the activities in the Physics department at Panjab University. Prof. Devinder Mehta welcomed the participants and the resource persons, and gave a succinct of the refresher course. Prof. R. Srinivasan told about the continuing efforts of Science Academies in establishing the Refresher Courses at various places in India, especially at Jalahalli Annexe of the Indian Academy of Sciences, Bangalore. Prof. R. Srinivasan arrived Panjab University on 8th Feb., 2014. He opened the boxes containing the experimental kits and set up the experiments in a 3-bay laboratory. Six computers with printing and internet facility were established in the adjoining M.Sc. Practical laboratory for the participants of the Refresher Course. Prof. R. Srinivasan, Dr. T.G. Ramesh (NAL, Bangalore), Dr. J.S. Shahi (PU), Dr. Suman Mahendia (Kurukshetra University), Er. Neeru Choudhary (PU) and Er. Manish Dev Sharma (PU) were the Resource persons in the course. The first four days were devoted to lecturers on the experiments to be conducted in the course. At the end of the fourth day, the participants were divided into groups of two to conduct the 17 experiments (List attached as Annexure-B). Laboratory sessions (18 nos.) of
three hours each were planned for the participants to conduct experiments (Time schedule attached as Annexure-C). The laboratory facilities were available to the participants as and when required, even on week-ends and late night hours so that participants can complete the experiments comfortably. All experiments worked well. Some problems were noticed with the Lock-in-Amplifier kits at the end of the course which were send to M/S Ajay sensors, Bangalore for repairs. The participants showed great enthusiasm and carried out the experiments thoroughly. Many of the ideas especially related to Phase locked loop, were also useful for the participating Research students. There was sufficient time and opportunity for closer interaction between the participants and the resource persons. There were five especial lecturers delivered by Prof. T.G. Ramesh (NAL, Bangalore), Dr. Sandeep Sahijpal (PU), Prof. M.L. Garg (PU), Prof. Manjit Kaur (PU) and Er. A.K. Jain (PU). The lecturers covering a wide range of advance topics were highly appreciated. Prof. T.G. Ramesh talked about the shape memory alloys and also showed demonstration of shape memory effect. He also introduced thermoelectricity in greater details. Dr. Sandeep Sahijpal presented an overview of the origin and evolution of the universe from big band around 13.7 billion years to the present time. The various astrophysical processes related with the formation of galaxies, star and chemical elements were discussed. Prof. M.L. Garg from the department of Biophysics talked about Biomedical engineering and instrumentation with special reference to principles of diagnostic ultrasound and various pulsed-flowmeters, ultrasound scanning and imaging systems. Prof. Manjit Kaur talked about discovery of theoretical predicted fundamental particle Higgs Boson, the so called God Particle which recently was observed through the ATLAS and CMS experiments at CERN’s Large Hadron Collider (LHC). The Higgs Boson contributes to our understanding of the origin of mass of subatomic particles. Er. A.K. Jain talked about the PHOENIX kit based experiments and demonstrated the data acquisition and precise timing measurements using this microcontroller based kit. This kit is outcome of meticulous efforts of Dr. B.P. Ajith Kumar and his group at Inter-University Accelerator Centre, New Delhi, for the low-cost Physics experiments in various teaching institutes. All the lectures are well discussed and highly appreciated by the participants. On 25th Feb., Prof. Srinivasan himself took feedback on the refresher course from the participants both through discussions and feedback form. At present, the forms are with Prof. Srinivasan. The course came to conclusion on 26th Feb., 2014, with the Valedictory The experiment kits were packed and sent to Rajanundri in Andhra Pradesh, the place of next refresher course. Prof. R. Srinivasan on the behalf of the Science Academies presented the experimental kits worth Rs. 65,000/- to Prof. Manjit Kaur, Chairperson of the Physics department. The
refresher course certificates were distributed to the participants by Prof. R. Srinivasan and Prof. Manjit Kaur. Students were given the electronics books – Electronics Principles by A.P. Malvino, Operational Amplifiers by Coughlin and Driscoll; and Principles of Electronic Materials and Devices by S.O. Kasap, which are very relevant to the very concepts on electronics used in the various experimental kits used in the refresher course. Prof. R. Srinivasan and Prof. Arun K. Grover, Vice-Chancellor, discussed to start the process for some sought of understanding so that Panjab University can be the Centre for conducting such Academies’ courses in the region. An exhibition of Arts works of Mrs. Radha Srinivisan of National fame was held in the Department gallery. It was highly appreciated by the students and faculty of the department. Week-end tours to Kasauli (Himachal Pradesh), Pinjore gardens and various places in Chandigarh and Punjab were organised for the interested participants. Prof. Srinivasan, Mrs. Srinivasan and Prof. T.G. Ramesh could also spare some time to visit these places. Resource persons and participants stayed in the PU guest houses and the DAV college Guest house. Breakfast and Dinner were made available to them at the place of stay. Daily lunch and tea/snacks were arranged at the Department. Special Lunch with the Faculty of the Department on Feb. 25th Feb., high tea at the Inauguration and Valedictory functions were arranged. The Vice-Chancellor and other academic dignitaries were also present on these occasions. All the guidance and financial arrangements for the course were provided in time and by efficient means by Mr. G. Madhavan and his team at the IISc, Bangalore and are acknowledged.
