What it is	You study physics and mathematics together as equal subjects rather than choosing one as your major. This combined degree lets you apply mathematical theory directly to physical problems, giving you a deeper understanding of how the two fields connect. The program suits students who are strong in both subjects and want to use advanced math to solve real-world physics questions, whether in research, engineering, or technology.	You study how the natural world works alongside the human systems that affect it. The BES focuses on environmental policy, conservation, and sustainability through social and geographic lenses, while the BSc emphasizes the physical science side: geology, ecology, and environmental processes. Both paths suit people interested in solving real environmental problems through either policy and community work or scientific research and analysis.	Physical & Environmental Sciences is a degree where you study the natural world through disciplines like physics, chemistry, geology, astronomy, and environmental science. You choose which areas to focus on based on your interests. The co-op option lets you alternate study with paid work terms in science-related workplaces, giving you real experience alongside your classes. This program suits students who want to understand how Earth and space work and prefer hands-on learning combined with classroom study.
