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.

    That consistent daily study is much. Much ore effective than spaced-out cramming Sessions.. Lasers can make things very hot. But we can use lasers to cool things down.

    Learning how a watch can work in outer space was crazy. It made me wonder if they would work in other places within the galaxy also

    Reply

    It’s amazing to think that a simple watch could operate in outer space. During the Apollo 13 mission, the Omega watch played a crucial role because it was the only one that still worked beyond Earth. The crew relied on it to time a 14-second engine burn — and if they had been off by even one second, they might not have made it back home.

    Wow! That is amazing how the Omega watch worked in space and on the moon. I always wondered if a watch would be able to work in space. When I was younger my Mom gave me a G-Shock watch since I was really active with boy scouts and sports. I used to think that watch was a space watch because it worked everywhere. I wonder how much an Omega watch would cost.

    I enjoyed learning about HAM radios and how they work. I also didn’t know that astronauts needed watches so badly, I’m sure the Apollo 13 crew were grateful for the extensive tests NASA did for the OMEGA watches.

    To start, I enjoyed learning about the best way to study. It’s been proven that consistent studying over time is much better than cramming overnight. This is because of something called Neuroplasticity, which is the neural connections we make with learning topics. So, by learning in smaller chunks, it strengthens the plasticity in our brains and allows for better retention.

    I also liked learning about cold lasers. Unlike the lasers we typically think of, which cut into strong materials with their heat, there are some lasers capable of cooling objects. It does this by absorbing low energy and emitting high energy instead of absorbing high energy and emitting low energy. With this type of technology, it could become another way to cool computer chips and open the possibility of quantum computers being created.

    Finally, I loved learning about a crucial aspect of the Apollo mission. One important part of traveling to the moon was keeping everything perfectly on time, which became a problem because most watches would stop functioning when faced with extreme heat or pressure. This led to a series of experiments to determine which could handle the extremities of space. The first experiment instantly determined two out of three watches to be unsuccessful, leaving only one: the Omega Speedmaster. Despite everyone believing that the watch wouldn’t survive the remainder of the tests, it turned out to be perfect for the mission.

    We loved the neurological reference in the beginning to building muscle at the gym and cognitive learning as our kids watch us exercise for health. This helped them understand the exercise of the brain. Also hearing you speak of repetition and step through Acellus so the information is retained as we compared public school cramming to test then forgetting. The kids laughed at the end.

    * Time really matters everywhere and for everything, so let’s use it wisely.
    * Lasers can be used to cool down parts of quantum computers. That is really surprising.
    * Radio waves help us communicate over very long distance.
