Physics Major

Physics Major is the science that explores the fundamental laws of the universe and serves as the foundation of modern technology. In today's era of rapid advancements in AI, quantum technology, new materials, and other fields, the mindset cultivated by physicists is emerging as a core competitive advantage for solving complex problems.

Introduction to Physics Major

Physics Major is the science that studies the fundamental laws governing matter, energy, and their interactions. Its scope spans from the tiniest elementary particles to the vast cosmic galaxies. Physics not only explains natural phenomena but also provides the theoretical foundation for technological innovation, earning it the title of “the backbone of science.”

The Physics major typically awards a Bachelor of Science degree and spans four years. The undergraduate program focuses on cultivating students' solid mathematical and physical foundations, rigorous scientific thinking, experimental skills, and problem-solving abilities. If mathematics is the language of science, physics is the “universe manual” written in that language, seeking answers to fundamental questions like “What constitutes the world?” and “Why do they move this way?”

Modern physics research expands toward both macro and micro extremes: macroscopically, from Earth to cosmic bodies, forming astrophysics and cosmology; microscopically, delving into elementary particles and the quantum world, forming particle physics and quantum physics. Simultaneously, physics intersects deeply with materials science, information science, life sciences, and other fields, giving rise to numerous emerging disciplinary directions.
