Radio Waves

November 12, 2025  •  EPISODE 286

How do invisible waves travel across the world and beyond? In this episode of Science LIVE, Dr. Roger Billings dives into the fascinating science of radio waves—how they’re created, how they move through space, and how they make long-distance communication possible. From the basics of frequency and transmission to early breakthroughs like Morse code and modern applications such as HAM radio and space communication, join us as we explore the hidden currents that keep us connected.

    Fun fact about Corals: They are ancient animals, related to jellyfish and sea anemones, that are vital to the ocean ecosystems, supporting 25% of all marine life despite covering less than 1% of the ocean floor. And some coral colonies can live for thousands of years, and many can naturally produce fluorescent pigments, potentially to protect themselves or help their symbiotic algae with photosynthesis!

    I enjoyed listening to Dr. Tobias talk about the Omega watch. I didn’t know that the watch played such a huge factor, to help the astronauts make it back from space. I agree about the student, who developed a daily study routine, this can help you retain the lessons. Dr. John’s information was really cool, the colors of the corals were so bright. Hard to believe that those are so far below the ocean.

    I think that a ham radio activity and Morse code course would be really interesting, and the idea of a pilot course could really help to inspire a future generation of pilots who didn’t even know it was their dream yet. On that note, I think that high school courses catering to larger genres of career paths would assist students in finding what they want to do in the future or go to college for.

    The coral facts were very interesting. The Omega watch, making it to the moon and still working, is so cool! I never knew a watch could survive in space until now.
