Physics & Astronomy

York houses one of Canada's leading Physics & Astronomy departments.

You'll gain a thorough understanding of fundamental concepts in physics, such as classical mechanics, relativity, modern optics, electromagnetism, quantum mechanics and statistical mechanics. Three streams - Applied Physics, Astronomy and Physics - allow you to focus your studies. The Physics stream offers the most flexibility in choosing your direction in third and fourth year. The Applied Physics stream focuses on more technological areas such as electronics and optics. The Astronomy stream emphasises cosmology and observational studies of planetary and galatic objects.
