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 comment is missing. i think it is wild that a computer chip is thread like, and that they based the design off sushi.

    What real use could having a small computer on the sleeve of your shirt really be? It seems like it would be more of a hassle, yes it could survive the heat of a washer, but could it survive the constant rumbling? Being crunched up? What would power it? I just don’t see much use for it, when we already have a phone in our pockets 90% of the time, so what could this be useful for that we couldn’t already do? The idea for paralyzed people would be amazing, but I just don’t see the benefit in shirts.

    the fact that we can fit a computer in a thread that is able to be twisted in 180 turn and not just stop it from not working is the best that is why science is just great
