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.

Fun learning episode!
Super cool videos, I love science live!
when you think about it wi-fi is such a strange name to call internet service. and it’s a random name which is also weird
I love radio❤️🥳
These are awesome, Stay warm guys, God bless!
Loved learning about the black hole, computer, and radio!
Hello from Miami, FL
Acellus has come a long way! A lot more students are passing than before Acellus!
I loved learning about radios
I loved learning about the radio
Hi from Maryland
Who invented the first helicopter?
What was the world’s first camera?

Hello from North Dakota. It’s cold!
Science Live is my favorite part of Acellus.
Radios are super cool!!!
Did the teacher let him come back to school after that.
I think that it would be really cool to have computer clothes!
This science live has to be my favorite! Can’t wait for the next one.
I love watching the science lives!!!
Accellus makes our learning relevant and fun
I really want a telescope.
Learning about IEEE was soo cool! I’ve never heard of them before
Sometimes I forget that Acellus is used by in person schools and not just for online use so its cool to see students in regular school succeed because of Acellus like I have.
Would the size and length of the computer strings effect how well they work?
Caleb,North Carolina. I would like to buy it with credites.
Would love to learn more about black holes.
Great episode this week, cool to see how the radio used to be
I like learning about radio’s
Why do some radio stations sound clear while others have static? thanks
I love science live!
it’s so amazing how computers are made!
This is my first science live, and I think its amazing how these videos are streamed weekly. I loved this episode! Looking forward to next weeks.
Acellus is the best
I am so glad to have wifi and not a bulky laptop!

It’s cool that you can make a radio at home It’s just amazing.
R-51 is so Goofy!
The Video has very interesting
and cool stuff the stories and the inventins !!!
I think it’s an eye opener to see how much Wi-Fi has changed our world. Without Wi-Fi, it would be slower communication than the 5g network we have today.
i love Dr Billings!!!!!!!!!!!!!!!
I think learning about the black hole was super fun to learn about!
this week’s live is cool. I had a good time watching it.
I loved this video. Learning about the black hole and radio was really fantastic !
What are Blue Monster Galaxies?
I liked learning about the computer chip that is flexible
It’s quite impressive that they turned a computer chip into a thread that is so flexible! It’s fascinating in my opinion. I’m excited for next weeks episode!!!
This was an amazing episode with very useful information. I’m looking forward to next episode!
R51 was so funny.
I like learnng about the radio and the black hole. it so much fun
I want one of those radio kits! Please allow us to purchase outside of the store too because I just started this program and don’t have enough gold coins. Also, please creative an elective class with Caleb and David! I love those guys! Maybe it could be a class on making stuff like a fox hole radio or doing experiments at home!
Loved the video !!
Interesting. I never knew a computer chip could come in a string.
i have started to love science recently because of these lives.
Smart clothes seems like an interesting concept
radios are so cool, there so inporntant to history
Science Live is the best!!
I would love to have a radio in the gold store!! And loved learning about hearts and radios!
Technology has been very innovative throughout the years. All the research and internet that has made tech use so significant in the 21st century is brilliant. Each day tech is becoming more broad and advanced. This video is very informative, it makes us understand the internet more.
I want the radio in shop and to put it together my self
I love the winter butter fly
It’s neat how radio tuning came about!
Can you make a Science Live about how WiFi was created?

I always assumed that Wi-Fi was named that because it meant something. I also thought radios would be a lot harder to make.
I love Acellus and how it is such a good learning program.
Area 51 is so cool! great episode
loved this science live!
I love science live!!
I love the James Webb telescope. There was an entire presentation at the US space and rocket center in their planetarium and it was amazing.
Thred computer idea: Baby pajamas that monitor vital signs and transmit the data to parents.
Radios and technology is so fasinating! Thanks for the lesson!
I loved today’s lesson. It’s so weird to know without Wi-Fi our world would be so different.
I’ll make sure to bring my tuned radio for camping.
It was so cool learning about WiFi!
I LOVE acellus
What is the oldest thing on the internet?
I would like those radios to be in the Acellus Store.
How old is the internet?

here from az
Radio’s are neat. we got snow this week.
These Science Lives are so interesting. I can’t wait for the next one.
Who created the first coil?
here from Az
It was really fun learning about the tuned radio!
Science live is so amazing
I loved the computer string, i thought that was really cool. this video has taught me how easy a radio is to make and i might just make one at home.
I learned a little bit about Marconi from Story Bots on Netflix but didn’t know his first successful radio transmission was December 12. That’s my birthday.
no WiFi in the world would be crazy
The computer tread is really interesting. The world and technology has come so far!
A computer chip in the size of a piece of thread is amazing!
I think the fishing line computer technology is neat, but not sure I would want it in my shirt.
Loved the video, can’t wait to learn more next week!
The Wi-Fi Radio. Is so cool! I want one with my points 🙂
I am really glad that Wi-Fi is as advanced as it is today.
What part of radio actually decides what station we hear when we turn the dial?
Can all phone be washed in a washing mesine
How long can the computer thread be made?
I think r51 is cool
I like having the protégés on science live.
WIFI has come a long way and now we use it for everything.
So interesting! i love learning and watching these videos!
Our world would be vastly different without Wi-Fi. It’s remarkable how much we depend on it, and I was surprised to discover that “Wi-Fi” is simply a made-up name.
I love science live:)
I liked learning about the wireless telegraph
I vote Radio kit
Could the computer string be used inside Smartphones to make them more compact?
The toilet paper roll unboxing was the best part of this episode. Super educational!
I love learning things in science live!
Black holes are fascinating!
