With its wide scope and its status as the foundation for many scientific disciplines, physics enables you to understand all forms of mass and energy and their interrelationships. You will explore how the universe works—from the subatomic and molecular levels to the scale of solar systems and galaxies—through systematic observation, theoretical modeling, and experimentation. And fulfilling Southwestern’s innovative Paideia approach to education, physics gives you the tools to make connections between seemingly unconnected phenomena in technologically innovative and artistically creative ways. How is DNA related to the dust swirling about a star? How does the strumming of a guitar or the darkly dramatic register of a tenor trombone behave like a wave traveling within the depths of the ocean or the tremors of an earthquake? You will develop the intellectual and philosophical curiosity to understand first physical principles—foundational concepts that lead to the scientific discoveries that shape our world and drive the technological advances that help improve our lives.

With specialties in geophysics, atmospheric physics, mathematics, and quantum physics, our award-winning faculty offer a rich array of courses, including earth and climate science, classical mechanics, and quantum physics. If your passion is for engineering, you can explore the field in our three-year, dual-degree Applied Physics Pre-Engineering Pathway. You will also have the remarkable opportunity to use the Fountainwood Observatory for research and coursework. Thanks to a generous gift by Max Allen, a local engineer, builder, and amateur astronomer, our observatory houses a research-quality reflecting telescope complete with a digital CCD camera that enables you to for view and process images on your computer.
