From the historic campus of Hillsdale College in Hillsdale, Michigan, where the good, the true, and the beautiful are taught, nurtured, and honored, this is the Radio Free Hillsdale Hour, bringing the activity and education of the college to listeners across the country.

There's several things I find interesting about the dark matter search, and that is there's a lot of these really sensitive detectors set up or being developed to detect other things like neutrinos and things like that.

And what people are discovering is, oh, we didn't detect the thing that we wanted, but surprise,

we just created a really sensitive dark matter detector.

This is your host, Scott Bertram.

Welcome to the Radio Free Hillsdale Hour, part of the Hillsdale College Podcast Network.

That was Dr. Paul Hosmer, chairman and associate professor of physics here at

Hillsdale College. We'll talk in depth in a moment with him about 2025, the year in physics.

And later on in today's program, we talk with Dr. Yvonne Pongrassick from Hillsdale's

economics department about his double life as a surf guitar player. First, we're joined by Dr. Paul

Hosmer. He is chairman and associate professor of physics here at Hillsdale College. Dr.

Hosmer, thanks for joining us. Thanks for having me. We talked at the beginning of 2025 and made

a note to do it again at the beginning of 2026. So we've made good on this.

The year in physics, this time looking back at the previous year, 2025, when we do look back

at 2025 in physics, what kind of a year was it? How would you sort of describe what happened

these past 12 months? Well, it was another really great year in physics. Physics is a

really exciting science. There's always really neat things going on. And I feel like it's been

successful every year since about 1687 when Isaac Newton published the Principia. And so we had

another really great one. So we had some really powerful theories, confirmed tantalizing discrepancies persist, which are always exciting.

Neat applications are coming into view.

And also global defense systems tested, which I think is really important.

All right.
