RAWALPINDI - United States Educational Foundation in Pakistan organised a lecture regarding the rise of computation in the study of science, at Fatima Jinnah Women University (FJWU) Rawalpindi here on Thursday. Timothy S. Sullivan, a Fulbright Scholar and Professor of Physics, Kenyon College, Gambier, USA was the guest speaker on the occasion. He is a Fulbright Scholar at the University of Peradeniya, Sri Lanka and his area of research is Computational Physics. The lecture was aimed at familiarising the students with this field of study and it was organised for the students of Masters of Computer Sciences and Bachelors of Software Engineering Departments.While speaking on the occasion, Timothy S. Sullivan said that Computational Physics is a new method to study Science beside theory and experiment. It is the application of computer simulation to solve the problems in various scientific disciplines. In fact Computational Sciences is to create a computer simulation of a physical system and then performing virtual experiments on that system, he told.He said that theory is a mathematical description of a model whereas experiments are always interrupted by in relation to a model. He was of the view that, in many situations theory and experiments became impractical and in such cases the Computational Science helped. He said that the scientific computing approach is to gain understanding through the analysis of mathematical models implemented on computers. The speaker also briefed the students regarding the prerequisites required for taking admission in this field. He advised the students to explore the opportunities to study and research in this field as computation is used in all professions today. He further said that this trend is producing innovative ways to learn and do research in the field of Science. The lecture was very informative and was followed by a question-answer session. In the end university souvenir was also presented to the honourable guest by Dr. Sikander Hayat Khayal, Chairperson Department of Computer Sciences, as a token of appreciation.
