Physics is fundamental to understanding our universe
Our subject matter underpins every other natural science, so physicists get to study everything from quarks to the cosmos. As exceptional problem-solvers, physicists use the most basic laws of the universe to attack its toughest questions. Whether you’re curious about how solar panels convert photons to electricity, or you wonder why black holes send ripples through space-time, the answers lie in physics.
Our professors will guide you through the pillars of the discipline—electricity and magnetism, quantum mechanics, classical mechanics, statistical mechanics, and computational physics—while preparing you to explore the forefronts of knowledge. (And we’ll do it in style, through a little something called Hawaiian Shirt Fridays.)
Why Macalester? Research
At Macalester, we think the real work of physics isn’t doing problem sets. It’s shooting laser beams at atom-thick sheets of carbon, or using telescopes to probe the nature of galaxies that are millions of light years away.
We live in such an exciting time for physics and astronomy. Improved technology is rapidly increasing the rate of research and discovery, both around the world and here at Macalester. And we guarantee our majors get to take part. Every single Macalester physics major completes an original research project of publishable scope before they graduate—whether they’re working at a professional observatory or side-by-side with their professors in a lab on campus. For previous projects, see our in-house journal of physics and astronomy.

30 August 2022: The 2022 edition of the Macalester Journal of Physics and Astronomy (MJPA) is available on Digital Commons. Check out the research of our 2022 graduates!
25 June 2021: Four Macalester Physics and Astronomy teams successfully participated in the RockOn 2021 workshop. Three of the devices they built will fly on a sounding rocket launched from NASA Wallops facility in Virginia. Estimated maximum elevation 75 miles. Splashdown in the Atlantic Ocean after a 15 minutes flight. The fourth device will fly on a HASP balloon mission in September.
28 August 2020: Congratulations to Professor John Cannon on his recent award from the National Science Foundation (NSF) to fund his research project titled, “SHIELD: The Survey of HI in Extremely Low-mass Dwarf Galaxies.” Working with undergraduate students this research will undertake a detailed study of the neutral hydrogen gas in the 82 SHIELD galaxies using data from ongoing Large Program VLA/20A-330 at the Very Large Array in New Mexico. This research program will be the most comprehensive investigation of the physical properties of low-mass galaxies to date.
4 June 2020: Congratulations to Professor Jim Doyle for winning the Janet Andersen Lecture Award from the Midstates Consortium for Math and Science in the area of Physical Sciences, Math and Computer Science. The Janet Andersen Lecture Award recipients are recognized as invited speakers at the Consortium’s annual Undergraduate Research Symposia (taking place at some future date).
