Tuned Radio
January 28, 2026 • EPISODE 295
How do radios tune in to specific stations? In this episode of Science LIVE, Dr. Roger Billings explores the tuned radio—how circuits are adjusted to select particular frequencies so we can hear one station clearly among many. Learn why tuning is essential for radio reception and how the first wireless radio signal crossed the Atlantic Ocean, launching a new era of global communication.

My mom says the same thing that not being to be able to believe everything on the internet
Could these thread computers be connected to the internet in the future? To have phones in your clothes would be cool.

I agree on not believing everything that you see on the internet
why does a tuned circuit resonate at a specific frequency? And I agree! Don’t believe everything you see on the internet.

Acellus has helped me so much. I was failing in public school due to lack of help. I am doing amazing with homeschool.
Is the computer-thread durable? What about if you accidentally bumped it or cut into it?
Tobias spoke about the IEEE how do they help the community and businesses? What other inventions did they design?
Hello from VA.
I’m interested in trying a radio kit
“How to study with Acellus Gold” was very informative. It was very nice to see how public schools are using Acellus to help better the students and ignite a passion for learning! I’m glad that public schools as well as home schooled students are able to benefit from this wonderful program.
Yeah you can’t believe everything on the internet especially now with AI all over it
These lives are amazing! Thanks again!
This is the best one yet

Love this live. Thank you so much for this video.
it sounds very interesting
How big are the transistors.
I find it fascinating whenever I hear scientific tales about scientists who aren’t from my country (USA). And that all different types of cultures of scientists can come together and create something connected.
