First Semester:  Dirac’s Term 2025

NAS members are deeply sorry for the passing, on the 16 September 2025, of Associate Professor Charan Promsuwan, a former Associate Member of the Tah Poe Group of Theoretical Physics (pre-existing theoretical physics community which was developed to the present Institute for Fundamental Study-IF) in 2003 at Department of Physics of Naresuan University. Charan has contributed, supported both mentally and academically to important steps in the development of the TPTP and physics community of Naresuan University. We never forget his contributions and memory of him.

Funded by ICTP (UNESCO-IAEA) Italy, the workshop is designed to introduce undergraduate students to essential computational techniques used in cosmology and high-energy physics. Through a combination of lectures, hands-on coding sessions, and interactive projects, participants will gain practical experience in simulations, data analysis, and numerical modeling—key skills for modern physics research.  Key Topics Covered:

  • Python for Physics: Learn to use Python libraries (NumPy, SciPy, Matplotlib, Astropy) for scientific computing.
  • Basics of Theoretical and Observational Cosmology: Dark Energy, Dark Matter, Current Cosmological Observations, and Monte Carlo Simulations. 
  • Particle Physics Tools: Analyse detector data, and explore statistical methods in high-energy physics.
  • Data Analysis & Visualization: Process real astrophysical and particle physics datasets, and create meaningful visualizations.
