The physics department organized a workshop entitled “Nonlinear Physics and Complex Systems” on Wednesday, November 28, 2018 between 8:30 am and 12:40 pm in building 6 auditorium, room 125. The workshop was inaugurated by the Vice Rector of Academic Affairs Prof. Mohammad S. Al-Homoud. This workshop was enriched with renowned international speakers namely; Prof. Lincoln Carr ( School of Mines, USA), Prof. Francois Peeters (Antwerp, Belgium), Prof. Bakhtiyor Baizakov (Tashkent, Uzbekistan), Prof. Usama Al Khawaja (UAE University), Prof. Abdulaziz Al-Haidari (KSA) and Dr. Majed AlOteibi (Kuwait University). The topics discussed were timely and of wide interest to the physics and general audience. They ranged from Bose Einstein Condensates to graphene then to complex systems in science and biology. Many of the physics faculty attended the workshop along with graduate and undergraduate students and asked a lot of interesting questions to the speakers. The coordinator of this workshop was Prof. Hocine Bahlouli, the coordinator of the Theoretical Physics Research Group at KFUPM. During their presence at KFUPM the honorary speakers also met the chairman of the physics department Dr. Abdulaziz Al-Aswad and discussed matters that are of primary interest to the department. In particular it was suggested that interactive physics should dominate the physics 101-102 fundamental courses in order to increase retention of good students and improve their appreciation and understanding of fundamental physical concepts.
