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.

RADIO WAVES ARE COOL!
Always nice to be educated on the origins of things and how things work on these weekly videos.
I loved this episode, what a different world we would live in with out internet, my mom said it was great without it though. LOL
Radios are actually so cool!
what are blue monster galaxeys?
How far away are blue monster galaxies?
I was surprised to learn that Wi-fi was just a made up word, I always assumed it was short for something. Regardless, it was cool to learn more about how it was first created.
I thoroughly enjoyed the lecture today, more specifically how much effort it took to make radio signals travel across the ocean. I was also shocked when I found out engineers tried to place a wire across the ocean.
I love watching science live its so entertaining and i love learning about how everything works its really cool.
It’s very cool how the Wi-Fi changed overtime and how much we use the Wi-Fi now because we have more technology and have artificial intelligence.
black holes are so cool!!!!!!!!!!
the part of the video with the radio was real cool and just science is amazing.
I loved this science live!!
the part of the video with the radio was real cool
wow thank you for another great live!
I love watching these lives! Hi from VA.
It was cool to learn about tuning radios, their signals and frequencies.
I really like Acellus!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Black holes are so interesting! This was a good episode.
Butterflies migrate to summer they move cuz of winter and there’s no such thing as winter butterflies
And the thing with the ship it was funny with the song
This was the best science live y’all made.
Those threads are really cool
The Evengeniers are awesome!!😁
I liked watching the science live it was very educational
Loved learning about Wi-fi today, I truly thought the name had some purpose though!
I always thought it was named wi-fi for a reason, but I guess they named it because “wi” not!
the fact that transistors need to be not only need to be in a certain but need to zoom in the see ALL the transistors and how small transistors can be amazes me.
Science live is always so interesting!
Wow, I didn’t know Wi-Fi connected to my iPad and it’s wireless
I am blown away that they can make computer components so small that they can fit into something as small as thread, and that they could be used in the future to make smart clothing. I want to build a radio that can tune into R51!!!!!
Wi-fi is great! I can do acellus classes anywhere!
how do you think they build devices like computers so small that they fit in a thread?
i wonder why they even made the first name “IEEE 80.11” then just change it to “wifi”
Watching from New Orleans!
The radio segment was really intriguing!
The computing thread thing was very interesting!
I loved learning about the radio!
Science Live is awesome!
Smart clothes? Sounds pretty cool to me!
these lives are super cool thanks dr billings!
its crazy that computers used to have to use vaccume tubes to work
Thank you for this new information
I love science live
This episode was really interesting!! I can’t wait to learn more in the next one!
The radio content was interesting. Ready for next week.
so cool I always love the science lives and R 51 is always so funny
I love Dr Billings!
Smart clothes sound very interesting.
Science Live is always so interesting!
R-51 made my day! Winter butterflies!
This is one of my favorite videos yet!
Thank you for this weeks sience live!
I always look forward the these videos, thanks
I love Science Live!
This is so cool!
black holes are so interesting :3
r51 is one of the funniest people I know.
Now, I think that the Protoges are my favorite part!
This live was very interesting!
it’s crazy how tuned radios work and how computers work! So interesting
I liked the frequency part
i loveee R51 he is so funny!!!!
This science live was epic!
I like dr billings
The protégés is probably my new favorite segment, they’re so funny. It’s cool to see how radio waves work and how they figured out how to change channels. I also think that the radio kit sounds really fun!
I love learning about black holes I’ve always found them very interesting!
It’s funny how wi-fi name has no true meaning behind it.
I love the jokes !!!!
I wonder will all clothes have these installed or certain brands. These would be good to track missing people.
it was interesting learning about radio waves signals were used for communicating.
I love Dr billings
Hello Accellus! Thank you for hosting this amazing Science Live every week, I really enjoy learning.
I would like to learn about Radio Tuning
I loved this live!!
The radio and sound frequencies are cool
i love Dr billings
I love radios, thank you Science Live!
Thank you guys for this video its awesome!
it’s cool how Wi-Fi was made.
I love this video! Can’t wait for next weeks!
radios are cool
I love science live
Its so cool how radios work.
In this week’s episode of Science Live, “Ep. 295: Tuned Radio”, Dr. John in the ‘Technology Spotlight’ segment talked about the computer chip threads created by researchers in China. In the ‘Science Breakthroughs’ segment, Dr. Tobias talked about an Australian inventor by the name of John Sullivan who attempted to create something that could help him see a black hole but failed, meanwhile, an American company called ‘IEEE’ attempted to create a WIFI system for portable devices that we know of today. In the final segment of Science Live, Dr. Billings talked about tuned radios.
I like learning about black holes they are very interesting.
I ❤️ science live!!
I’m amazed on how many children joined the school just for Acellus
I have missed a lot of episodes, but am so happy to watch again.
I love science and engineering!!!
I never knew you can just tie and do things with the computers cables. there is so many things you can do with that.
we need to bring radios back.
I think it’s pretty cool that the radio station is able to reach such a far distance and basically having a computer in a thread is awesome.
The computer is so cool!
I read a book last week about how they used morse code a lot in World War 1.
The blue monster galaxies is such a cool name for it I will definetly be researching more about it.
its absolutley crazy how much wifi is used
I find it funny how Wi-Fi was named, and how the name had nothing to do with what it is 😆
Its cool that WI-FI is a made up name.
They finally finished the wiring only for it to break three weeks later, glad we can use radio waves.
Crazy how people invent all we have today.
Computers have come so far. I love Wifi. Not sure how I would survive without it.
This is awsome can’t wait for the next live!
Hi from Virginia
I loved this science live! Keep up the great work!
Smart clothes? Like the glasses that record, would those fall under that catagory?
Thank you for this weeks video I really enjoyed watching it
i think the smart clothing would be cool
The protégé’s are doing fantastic! Keep up the good work guys!
How does this concept apply to real world situations outside the lab?
I love this video so much.
Learning about the radio was so cool.
Do we have the technology to listen to black holes?
When will the radio come out and how much will it cost?
Dr. Billings is my favorite on the show
I love science live!
I like learnng about the radio and the black hole
I love asl its my fav class, and I like black holes.
The underwater cable was an interesting solution that didn’t work out very long, but led to a cool invention.
My favorites are David and Caleb!
why do black holes suck up stuff? is it some type of pressure that causes them too?
r51 is so funny😂🤣
Put R-51 radio in the gold store please pretty please with a cherry on top.
I can’t imagine how different the world would be without radios!
Brain implants for communication sound pretty cool.
i love acellus theres so many new things i have learnd.
It’s cool how Samuel Morse created Morse code.
I never thought of a computer chip as a thread!
These are my favorite part of the week!
i love this show
I feel like I learned a lot more this time around. I’m so glad science live exists.
Love science live!!!
The graph with WiFi speed was really neat to see and compare to everything else.
love these videos cant wait for the next one.
computers in pice of thrad is a cool idea.
im on team r51
What are the plans for the new competor chip beside maybe having light up fabric.
I think it would be a good idea to put the radio in the Acellus store.
This lesson was very interesting!
That was cool about the carbon atoms and carbon nanotubes. I did not know that about USB and about SD cards.I want to do the science but all my inventions are really terrible and do not work. Do you have any advice?
amazing video cant wait for next week.
It’s cool to see how this whole technology was made by people who didn’t give up on their inventions. Nice episode!!!
I like the R 51 radio, which is a radio with a little speaker. The radio only tunes into 1 station and that’s R 51.
Them unboxing the TP hloder was funny!
I love this program.
I love learning about the new technology and how the past technology came about each week during Science Live. Another great Science Live. Smart clothing would be cool to have I think1
This episode was very interesting!
This was probably one of the coolest episodes.
I think it is fun that I could make a radio at home.
Dr. Billings I was wondering if you could add a slow speed on all the classes it would’ve helped in the German class I did.
I thought it was cool that I could be able to make a radio at home!
why did scientist believe radio waves would shoot off into outer space?
Science Live always has something cool to teach me.
This was really a good watch, loved learning about radios!
Will the thread be able to run a program on it or no? I’m interested!
I thought the computer threads were cool.
That was so cool!
Hello! I liked learning about the radio
I want to build a radio!
Radio was a great video!
Loved this science live!
I never really thought about how radios work thank you for this info!
Thank you for the scholarship! I enjoy the videos, Dr Billings!
It’s crazy how technology and signals continue to improve each year.
A radio channel that works on WiFi is very cool!
Im amazed about how much I learned by just this video!
The energy was nice this episode! As always, I’m excited to see more. Thank you!
I think black holes are an interesting subject, along with our universe
I live by the Atlantic Ocean in Maryland!
I really like watching R51. He’s funny.
I liked learning about the radio!
Awesome video can’t wait for the next one!
Thank you dr. Billings for explaining how radio waves work.
