It’s like how I’m learning how to play the piano right now! I have to remember and sometimes it’s really hard
There is a lot I didn’t know about radio waves.
That’s so cool
Love this
Interesting episode about invisible waves.
I did not know a watch could be in space amazing. happy very late new year from Utah
Learnig about radio waves is very fun.
This was so fun to listen to!
Neat to learn the difference between AM and FM frequencies and why FM radio sounds better
Another good video.
It’s still surprising how radio waves move all around us without cables, such an amazing thing.
Coral looks really cool up close.
I learned that we have great communication
Love this so much!
I am all into radio waves now
Thank you for this!
Thank you for sharing all this great information with us!
i loved this
I love radio waves so I can listen to music with my family.
I always wanted to know how i hear my friends on the game, That is amazing how this works
breaking the sound barrier is crazy!
Here from Tennessee. I love learning
radio waves are so cool to me, the science behind them is so fascinating
This is amazing!
I think how the watch in outer space was cool
So crazy how there all around us but we can’t see them
I think this is very interesting and always wanted to know about this.
I did not know that lasers could cool things down when something fluoresces which helps to cool something down. I also was unaware of how much detail goes into every aspect of what goes onto a spaceship. You explained the wavelength concept well to help me understand it better. I liked hearing about the differences between AM and FM stations as well, I always wondered why FM sounded better.
I liked learning about radio waves.
Radio waves are really interesting thank you
The invisible waves are so intresting!
I love these so much
How do invisible waves travel across the world and beyond
Science rocks!! I’ve also been trying to learn morse code for fun
Me too
That lizard is funny
An insightful episode exploring the fascinating science of radio wave communication. I love it.
I never knew what frequency meant before.
Man absolutely loved this lesson. It’s always amazed me how cool different waves are especially radio waves! Also loved the lizard haha 😂🫶
I liked the lesson! Radio waves are invisible, but they are all around us. They help the radio play music. It’s like magic!
hearing about the apllo 13 mission and how important the watches were is really cool
I love these so much
Radio waves 🤯
Radio Waves are very interesting!
There’s always such interesting facts in these lives!
My grandparents and great grandparents were both HAM operators. One even had their handle as their license plate.
An aviation course would be awesome!
I don’t know what the world would do without radio waves
Sometimes you just have to stir things up a bit, right Dr. Billings. Love your radio voice. Thank you for sharing your experiences with us.
The “Pajet makes me believe in myself” T-shirt is awesome!
I love learning about Radio waves cause I’ve always wondered about the like fields of any waves and how it worked! This helps a lot!!!
Made a bracelet using morse code once. Long beads and short small beads were used to spell whatever you wanted on the bracelet. I wrote “I love you” and gave it to my mom.
Hearing about the lasers was fascinating! I didn’t know that they could be cold and function like that
I never knew what AM and FM meant before, that’s so cool.
I love science live.
I find it really interesting how radio waves are used for everything from texting and communicating to WiFi pretty cool.
What did one gig say to the other
hey that hurts!😂🤣
Love science!
Does the color of an object affect how hot it gets in the sun?
I really like this class
I never know how important radio waves were i can’t imagine life without it.
I cannot imagine life without radio waves
science is awesome!
I love learning about this stuff it gives me so many tools to put in my tool box
I want to go to outer space
The HAM radio sounds interesting and I think I’ll do my own research on it as well.
This science live is amazing!
I was not aware that a laser could cool objects.
That’s some amazing knowledge
Hello from Texas I’m enjoying Science life
Radio waves are crazy how they work.
I learned a lot of cool things from this lesson like what frequency is and radio waves
This is so awesome and interesting!
Thank you Mr. Billings!
Awesome thank you Drb
My dad said I should buy a radio.
How can I be more consistent when studying?
My favorite part of science live, is hands down Tobias! He’s so entertaining… I love anything he talks about. I never has thought about the timing issue, but that makes a whole lot of since why timing would make a HUGE difference!
My favorite part of science live is listening to Tobias speak. Love the bit he did on watches!!!!
i love rewatching these lives! they’re amazing!!
Hello from Guam.
Having a HAM radio sounds like a fun pastime! It sounds like the people on there are friendly.
Watching from Minnesota!
how long can someone stay in space?
I love science! Technology is so interesting to learn about as it becomes more advanced!
I love learning about things like radio waves, because they made huge impacts on our lives!
Thanks for the science live!
Science is my favorite subject
How many colors can the coral change?
When I went to the science museum, they had a Morse Code machine. I used it to make my name. It was hard at first to get the right sound and pause to type each letter. I liked using the Morse code machine.
It is so incredible that the omega watch still worked on the moon and saved the Apollo 13.
It was fascinating to hear about all the testing that went in to the watches for space travel.
Science live is the only way I like to learn!!
I always can’t wait to watch science live every friday. I wish could watcha new episode everyday.
I can’t imagine not being able to know the time!
Even my mom learned more about radio frequencies.
Dr. billings is the best!
I didnt know there were different frequencies!
Science live is great
Can you feel radio waves?
I never knew lasers could cool things down! It’s amazing what we can manipulate things to do.
I want a HAM Radio.
I have always loved music and I hope that my future career I can accomplish something involved with music and dance.
Science is awsome!!!!!
So cool about the first watch making it to the moon
Do they still sell omega watches today?
This makes me wanna go to the space even more
why do northern lights happen only in cold enviornments?
radio waves are so cool thank you Acellus I am learning so much
This is by far my favorite episode. I’m fascinated with radio waves because of the way they communicate with other devices. Dr. Billings explains everything so well and understandably.
Thank you Dr Roger
It’s crazy to think about without our radio waves we wouldn’t have electricity like we do today
My Mom watched this one with me and told me about sitting in my great grandfather’s lap while he operated a ham radio. He was in the Navy and I also learned that he was a ham radio operator during WWII. I think it would be amazing to have a class on ham radios. Also on Morse Code! My mom also talks about cymatics and frequency – I think those would be cool science lives too!
We love corals and all the amazing colors under the sea!
I liked the omega watch
My step dad does HAM radios. Interesting how it works.
Science Live has helped me learn so much more about science!
living on the moon would be crazy
i love the funny guy
That’s cool that a watch went to the moon!
I like Science Live
I love these
Thanks for sharing. Who would have thought someone would invent radio waves from copper and a glass and touching it. It seems impossible; even though it happened. This is very entertaining. I will probably be dreaming about something related to the video.
Radio waves are so intresting.
interesting lesson!
Hello! Great video. Science Live is so interesting!
i <3 science especially earth & space
How does a wavetravel
This was an amazing lesson!
I think that radio waves are interesting.
What places today still use ham radio?
Wow I would have never guessed radio waves were a thing!
how long can someone stay in space, and what would the side effects be after returning back to earth?
Tech is so cool!
With society relying on radios and technology so much, it’s hard to imagine what it was like for people before radios and so much of our technology were invented.
Interesting, Im learning alot.
Science Rocks!!
Just imagine living in time before radio waves were discovered. Technology keeps advancing. So much of our lives depend on it today.
If AM varies amplitude and FM varies frequency what the technical reason FM handles static better while AM travels farther?
I never knew what frequency meant before.
I really like the science live classes:)
Is the HAM radio the same or different than a CB radio?
Yes CB radio and Ham radio is much different. CB radio has a much shorter range and does not require a license. It also can only operate on one given frequency while Ham radio can operate on almost all frequencies. Ham radio requires a license and can operate on a ton of frequencies, plus gatherings such as Ham fests and communities are also created with Ham radio.
Great live!
Tobias’s lesson on the watch was very interesting!! Love the shirts!
how long can someone stay in space ?
Destiny here, hi from Alabama!!
Mississippi 😎
I love all the colors of the coral! It would be cool to see them in person!
I would want the aviation class it sounds realy nice!!!!!!
I like the parts with R-51 at the end of the science lives. Sometimes they’re very funny.
Thanks for the awesome video. I was wondering two things. One, do people still frequently use the HAM radio and also, who came up with the idea of morse code
this is so cool! okay so is it possible for someone to see radio waves?
I never would have imagined lasers can cool things down. Science live teaches you new things everytime
Good lesson 👏 👌
Science live is so interesting!
Thank you so much, Dr. Billings. I enjoy your videos.
I think being in space as an astronaut would be awesome. I’d love to see space and radios there
Happy Thanksgiving 🦃 everyone at Acellus. Great motivating science love. I think a class with pilot education would be amazing or a asa extra activity to see how well you can fly with a simulation. I also think Morse code is great to learn so is HAM radio. Also if classes had diy safe things to make at home.
It is amazing that lasers can cool things down!
Thank you so much for this one – my dad said next year we can work on building a radio!
I thought this was going to be boring but it is fun and really cool i am surprised
i love learning with acellus!
Today’s science live was awesome!
We learned about Morse Code last summer – it is so cool!
is it possible for someone to be able to see radio waves?
I liked the part about the robots
This video is awesome I love science live!
My grandparents and great grandparents were both HAM operators. One even had their handle as their license plate.
An aviation course would be awesome!
I did not know a watch would work in outer space. Very cool!!!
Wait, how long astronaut can be in space?
This is one of the most fascinating inventions that I have ever heard and seen! Thank you Acellus for sharing the information and keep inspiring students!
The quantam computer is crazy.
I like the Morse Code part of this video and how it works. I like how you can send different signals through morse code.
This is very educational and helps me get a better understanding, thank you science live!!
What are different types of radio waves and their uses?
Acellus is wonderful!
Thank you ☺️ Happy Thanksgiving
One day my songs will be played over the radio waves
I believe that they will!!!! =) <3
Happy Thanksgiving to everyone at Science Live!
You too happy Thanksgiving
I know I’m late to this one but I was super bust the other week so I wanted to come back and watch this anyways thank you so much for always helping me learn something new and amazing it is truly inspiring
I find it fascinating about the new semi conductors that are being tested right now that will impact our future. It seems that diamonds are a more important stone than just to be used on wedding rings. Science live is so interesting!
Acellus is great!
This is always so fascinating to me, radio waves. I’m glad to finally know what AM and FM radio actually means now!
