The Cosmic Classroom

In this episode, we continue our sound journey through the universe as we learn about the modern technique of sonification. We'll explore several examples, including what the center of the Milky Way sounds like. We'll also hear two of my favorite celestial bodies: Supernova 1987a and the Sombrero Galaxy. Come and join me as we take an audio tour of the universe. Join the discussion in the Facebook group! Visit the following websites to explore more examples of sonification: Chandra X-Ray

Ancient philosophers believed that the celestial bodies make music and move in perfect harmony. Astronomer Johannes Kepler coined the phrase musica universalis, also known as the music of the spheres. Both Pythagoras and Kepler believed that music could heal the soul and that the harmonies of the cosmos could only be heard by the soul. Do the planets and stars make sounds? What would they sound like if we could hear them? Join me as we begin to discover what Pythagoras meant when he said,

In this episode, we'll take a brief look at mathematical limits and then take a walk down personal lane as I recount a couple of examples where I went beyond my own limits and took risks that led to great personal growth and development. To quote Ronald Reagan, "There are no great limits to growth because there are no limits to human intelligence, imagination, and wonder." Join me, as I ponder the question, "What's the worst that could happen?"

This episode's mini-lesson is about units--why they're important and how to use unit analysis as a quick check to see if your equation is correct. Next, we'll talk about time. Who first recorded time? Why are there 24 hours in a day? Does time even exist? Join me, Sarah Tyk, for a random walk through the fourth dimension.

Hi! This is The Interested Reader podcast and I’m your host, Sarah Tyk. I’m a mom to a 1-year-old, a wife of 17 years, and a lifelong lover of science, nature, and learning. In graduate school I was a teaching assistant for physics, astronomy and environmental science courses. This is when I discovered my love for teaching. But following a curriculum and strictly adhering to a textbook wasn’t my thing. I wanted to learn about (and teach) topics that weren’t mainstream; that weren’t taught in the
