Why are diamonds good semiconductors?
Morse code is neat!!! I’d like to learn it!
How many years do you have to go to school to become an astronaut?
I liked the Speed Master watch. Is that what Dr. Tobias has?
Thank you for this weeks science live!!
i love science live, it allows me to learn something new every week!
this was our first science live, we are looking forward to many more. Loved the startup joke. Hahaha….
I like the watch they sent to space. I liked all the tests it had to go through. I also bought a new shirt with my gold coins! I can’t wait to get it.
How hard is it to get a job at NASA?
How do you spell Acellus in morse code?
we love ur stories ur amazing
How are radio waves classified within the eletromagnetic spectrum?
I love that I can learn so much Acellus is so cool
That was very interesting the apollo 13 mission watch story was very fascinating cant wait for the next one.
I find it interesting how lasers are used both to create some of the hottest things, like plasma in certain fusion reactors, and also to cool stuff down to (almost) the coldest temperature possible in our universe.
I love learning something new from science live each week!!!
I really like the Science Lives.
Learning about reverse temperature effects of lasers was awesome.
Radio waves are cool.
I love the break through science part of the video!!
My papa has his ham radio license!
Love acellus.
Its crazy that 1 second would make such a huge difference!
awww the hammer coral is so cute to me for some reason it looks like little worms
I love this school it’s helped me a lot
Acellus is an amazing learning tool!
This is our first week with Acellus and we are loving it and the science live videos!
An original Omega Speedmaster Moonwatch is selling for $8000 and up!
how’d snoopy become a mascot for nasa?
I love Acellus!!!
They always know how to cheer people up!
I love learning about science!
Hi I LOVE Acellus
Radio waves are cool thank you for teaching me about them.
Would love to learn Morse code.
I love science live!! I learn so much!
The radio is a very useful tool not only can it be used for civilians but also is a key item for the military.
I think that a course on ham radio and a course on aviation would be amazing.
Gotta love R51
Snoopy and Charlie Brown modules, and the Snoopy award. Too cute!
love these lives so much! So greatful for this program
Acellus ❤️
Its so fun to watch science Live. I learned a lot about radio waves.
science live is so fun!
I love Acellus!
It’s amazing how easily it is to break theories with just one simple test, that can eventually lead to great discoveries, and better technology.
Acellus is amazing!!
I love Acellus!!
I love how Acellus adapts to the student. It does not rush, does not judge, just keeps giving structured,understandable material. Very thankful for this program.
I love Acellus!🙂
Acellus is super cool, and I love that it is super flexible with my schaduel. Thank you so much for your smarts!!!
I had the honor of knowing a great man that worked on Apollo 13.
I love the Science Lives!!!
Acellus ♥️Thank you
I would like to meet Dr Billings. He’s a genius!😁
My favorite part of every episode is Breakthrough Moments in Science.
Designing a watch specifically for space travel sounds like an amazing scientific adventure
we love Acellus!!
I love watching the science lives!!
Radio waves are awesome
i think a morse code class would be fun
I enjoyed hearing the story about the Omega watches and how ham radios work.
I wish I could have seen the northern lights!
watching science live always helps me with my motivation and it really funny that this episode talks about working on being focused with your work while i have been trying to ways to stay focused with my work load.
Who and what inspired the discovery of radio waves?
I learned that the Omega watch was the only watch out of four watches that was approved and passed all the tests to be approved to be used by astronauts in space. I was not aware that astronauts used watches in space.
What do you think will happen with the new material and diamond?
When can you do the SAT?
I love learning about new things! Thank you!
Hi! Science live is so fun and interesting!
I love homeschooling, so I also love Acellus!
Science live is awesome
I love watching science live, it teaches me so many new things.
Radio waves are awesome. It’s the language of the universe I wonder how the technology will evolve. Maybe we’ll be able to decipher more complex signals and frequencies
science live is so fun, how did you guys come up with the idea to do it.
The radio waves are super cool!
I would not have guessed that one of the most important things you need when planning to go to space would be a watch!
I love Acellus I can’t wait for the next episode!
I thought that the laser cooling was a cool segment.
It’s insane how convenient Acellus is!!
The way the brain learns is cool.
I love Acellus and Roger Billings! Meeting my daily goals really helps me keep on track.
It would be interesting to learn about the Morse code if offered,
I loved the new suggestion on how to take notes during classes so it could be a more efficient and helpful way with remembering the lessons better.
I have loved learning with acellus!
I love science news!
I love the flowers of the ocean. They are so beautiful and alive, plus it shows you no matter where, life will grow anywhere.
“we love acellus!!” we scream in unison.
Acellus ❤️
Can radio waves be modified in any way to redirect to a specific direction or is that impossible?
Acellus is the best homeschool curriculum!!!!!
I love it its so much fun
What is the difference between Acellus and Acellus gold?
learning about lasers is super interesting
Science live❤️
I really enjoyed watching this weeks video I can’t wait to watch the next one.
Thank you very much! That was very interesting!
Cool lizard name: myka
The explanation of how radio waves are generated, transmitted, and received was clear and easy to follow. I especially liked the real-world examples showing how radio-frequency technology is embedded in everyday devices. The visual breakdown of the spectrum was also helpful for understanding why different frequencies are used for broadcasting, communication, and navigation. Looking forward to more episodes that explore the rest of the electromagnetic spectrum!
Developers for video games also use wave lengths for effects. It’s cool to learn more about how wave lengths are used in different things.
My grandpa had a radio tower
I really enjoyed learning about NASA using the Omega watches on missions. You always hear about the moon landing but not always all the different things that had to be researched and tested to be used on the mission.
Thanks for explaining about radio waves! That was my question last week. I want to learn Morse code!.
The quantum computer looks like something out of an old sci-fi movie.
what is a semiconductor
This really cleared up radio waves for me! Thank you to the whole Acellus team, and I can’t wait for the next science live!
I would be interested in pilot class. It would be cool if I could listen to science live on the radio.
Love this video so much!! I learn so much from these!
I really enjoyed your story from when you were just a boy and how you acquired your own radio tower!
It’s so cool how radio waves can be measured with amplitude, and wavelength like sin(x) and cos(x) waves.
COOL
As a HAM radio operator, I would personally LOVE to see a course on amateur radio, and a course on helicopter piloting. Please produce them as quick as you can!
My grandpa loves his ham radio and this episode was really fun to watch with him. He really enjoyed being able to share this with me and it gave us a new way to connect with each other.
You could see the auroras here in West Texas!
I wonder how that new semiconductor will affect technology in the future.
how long did it take to make acellus
I remember better when I study in smaller chunks vs cramming all at once.
We would love ham radio, Morse code, and pilot classes!!
I’m currently learning about different waves! I was forgetful and a little confused determining the differences for some, but this science live definitely helped me.
I would love an aviation course!
Can you write 📃 in Morse code
How do radio waves carry information without wires, and what makes them different from sound waves?
Woah, I didn’t know lasers could cool stuff down!
I had an great time learning about radio waves!
I love acellus!
First time! Love Acellus so far!
If we could see radio waves with our eyes, what would they look like?
I love Science Live!
Do astronauts wear watches to space today? Do they still wear Omega watches?
Comment Thank you for Acellus. This is a great program.
Thank you for the video! love Acellus
Thank you!
I would LOVE to have a pilots course!!!!!!!!!!!!!!
Such a great episode of Science Live.
Thank you for the video! Hello from NC!
I really loved the talk about the laser. I didn’t know a laser can make thing’s cold. So cool! It was so interesting to learn about. I love Acellus!
This program is amazing I went from not learning a thing in public school to actually excelling. I have even gotten a job, I couldn’t be happier!
Love acellus!
We love all the new information we learn from Science Live!
I like how the work is planned out with the daily steps and see how many steps we have left to do!
Radio waves have come such a long way today from when they where first even just an idea which is such an incredible thing to even think about how people can think of such smart things to help out in this world.
My Dad is a GMRS and HAM radio guru!
Thank you Acellus.
Love space. Can you live on the moon?
When are we doing a mission to Mars?
What a great science live! Thank you!
Awesome
Learning on Acellus is so fun!
what are the most common ham radio frequencies
This is awesome! Hey from Florida.
How did the rocks at the bottom of the coral area give off a blue florescent light when it was originally white? Is it because of the water surrounding it?
I learned something new by watching this video. I did not know Buzz wore a watch on the moon.
Is there a Morse code in other languages?
This video is really cool and interesting! I also learned a difference between AM and FM.
I love acellus!!!!!!!!!!!!!!!!!!!!!!!!!!
This video was really cool and interesting! I also learned the difference between AM and FM.
All members of the science live videos are all smart and fun.
I’ve always thought the concept of radio waves was extremely fascinating. A completely unseen but very present wave of sound, energy, and atmosphere weaving together to create a non-physical but incredibly important facet of what we hear, what we consume, even the media’s ability to reach us from around the world. It’s just so interesting to think about how something that isn’t physically tangible could be so important and wide-spread throughout the planet in connecting us with one another.
R51 always makes me laugh so hard.
That’s so cool that blue light causes fluorescent colors on different objects!
The technology spotlight is usually my favorite part of science live.
its so cool how radio waves work
r-51 is sooo funny
I LOVE science lives!
Acellus is amazing
SO COOL
R51 is my KING
I very deeply enjoyed this video and found lots of value in it.
r-51 is soo silly!
This was a great video! I love going to school here!
Thank you Acellus Team!
If would be fun to use older radios, kind of like they did in smokey and the bandit
How did hydrogen get made?
Loved the section about watches in space!
love Acellus!!!
Acellus Is Great!
