11. "' Pran Nath "'is a theoretical physicist working at Northeastern University, with research focus in elementary particle physics . 12. Other applications of his work can be found in elementary particle physics and in encryption and computer security. 13. His specialty was elementary particle physics . 14. Theories like the one governing elementary particle physics are based on simple principles with a distinct aesthetic appeal. 15. His original fields were nuclear and elementary particle physics but branched out into applications of physics in other disciplines. 16. ALiCEnext used in the field of elementary particle physics , applied computer science, astro-particle physics and experimental high energy physics. 17. Thus, he argues that certain paradoxical phenomena in elementary particle physics parallel the Banach Tarski paradox in set theory. 18. Recently there are 5 programs; Atomic and Molecular Physics, Solid State Physics, Nuclear Physics, Elementary Particle Physics , Meteorology Physics. 19. In 1963 / 64 he conducted research at CERN . In 1965 he became Oxford professor of elementary particle physics . 20. ECR ion sources are used as injectors into linear accelerators, Van-de-Graaff generators or cyclotrons in nuclear and elementary particle physics .
