Physics underpins most aspects of modern engineering, technology, and medicine. For example, about 25% of the world's economy is tied to the quantum mechanics of silicon, and many of the most important practical advances in chemistry and biology can be traced to the precise understanding of the behavior of atoms and molecules provided by quantum mechanics. Knowledge of physics is therefore vital to understanding the world around us. This calculus-based course continues on from PHYS1210 and covers the topics of mathematical tools, electricity and electromagnetism, optics, atoms and molecules, and quantum mechanics.
