thank you for another great episode.
I liked the laser part!
Love this episode! So cool!
I learned that radio waves can travel long distances, but their clarity and strength can change depending on its environment. Can you explain how different factors such as weather conditions or distance can affect how radio waves travel and reach the receiver? Thank you.
I love science lives!
I LOVE SCIENCE LIVE!!!
Thank yall for doing this science live every week! I really enjoy it.
I really love learning with Acellus
I really liked shirt #4.
Super cool!

How could diamonds be cost effective? Even lab created?!? Fascinating that they could be used as a conductor.
Are the omega watches still in use for going to space?
I love learning with Acellus!!
I love learning with acellus!
I learn something from every science live!
Omega should make watches for Extreme Sports.
Is Morse code still widely used today?
Do 5G towers use am or fm frequency?
Morse code is really cool
R51 makes science live so fun!!!!! He makes me enjoy doing science live a lot more!
Yes, I think a ham radio class would be good.
I never understood how important wave length is!
I love learning with acellus so much!!
Hi I am Nikara G from Virginia. I am truly enjoying using Acellus. Learning made easier is great. I like the math teacher, he is so funny.
my name is Delphine and I love to learn with Acellus and Morse code is cool. I like the R 51 did it shirt. It looks pretty cool.
I look forward to the next science live!
I love learning with Acellus. Area 51 this week was very funny!
Morse code is so cool!
I love to learn new things.
I didn’t realize radio tower are different heights depending on the radio stations frequency. Very cool show today now, I’m going to research more about radio frequency and radio towers.
I liked learning about radio waves and also r 51 is funny
Science is mind-blowing
I always enjoy listening to these, thank you for your effort.
I love watching these !!!
i love learning with acellus
Yes, helicopter piloting would be cool!
Science live is cool.
Science live ❤️
I love learning from Tobias! I wonder why we research space more than the ocean.
I love watching science live. I learn so much new information
I never knew that a consistant study helped the brain absorb information
Hi! I am watching it again. I can’t remember if I made a comment. I love learning about space and radio waves.
Studying everyday improved my reading. I do my best to read for 30 minutes a day.
R15 is so funny
Yes he is I like the lemon into fireflies video
I love science live and Acellus so much
I love all the new shirts!
DOCTOR BILLINGS IS INSPRIATIONAL
Quantum computers are really cool!
I want to see if I could learn “Morse code”! 🙂
I find R51 so funny!
Acellus is fun
Learned about energy light and lasers!
I love learning with acellus
thank you Acellus for all the knowledge
I have l always been so fascinated by radio waves and frequencies. Simply amazing. Thank you for breaking it down, and making learning FUN!
R51 forgetting how to count down from 3 is so funny
I love acellus and its the best!
I would love to learn morse code if you made the class
A morse code class!!!!! Cool!!!!!!!!!!
I liked the whole thing, But I liked the r51 segment the most. probably because I love joke characters the most.
Mind blowing live.
Excited for this journey. New here to Acellus
Memorizing Morse code seems really hard!
New here and excited for this journey with Acellus.
I would be interested in a course on learning how to fly a helicopter.
I love learning about apollo 13
Could waves of a different amplitude interfere?
I did not know that astronauts wear Omega watches.
Science rules!
I live in Idaho and I go to the Warhawk Museum a lot. They have a little Morse code table there. I just thought that was pretty cool detail.
I love watching these every week, I always learn so much!
Lazers are very awesome.
I love science live so much!!!!
I love watching these science lives!!
This episode was so insightful! I found the study of the brain part very interesting.
r51 is funny and cool!
The new classes sound great! How many new classes, besides the pilot and radio ones, are you thinking of making?
I love being able to learn with Acellus!!
When was morse code created?
I love watching the videos! It is my favorite part of the week!
I think that a pilot and ham radio class is a great idea. These shirts are worth checking out.
Have happy day.
I want to learn Morse code!
Science live is my favorite!
I love science! I was wondering what the most interactive part of our brain is. And what are the parts?
Just wanted to tell you guys I might be starting cosmetology school January 6th for free. Im so excited and I’ll be so proud of myself if I get to go. And I might apply for a job soon and Ive started studying for my drivers permit. And I can only do all of this because of Acellus giving me the time to do it.
I’ve always wondered what the difference was between FM & AM radio, thanks for clearing that up!
I love Acellus! I hope you can make an Airplane/helicopter class for middle school too!
I really enjoy learning with Acellus!
acellus is a amazing program.
R51 is so funny I need to get every shirt with him on them.
Having a Morse code class would be fun
Whats the practical application for lazer cooling in a modern consumer setting? Not for quantum computing but rather general computing. Could it be cheap or efficient enough to replace or work eith methods such as liquid cooling and general airflow heat sinks?
R51 is hilarious I love this live
I am so thankful for Acellus and all that if offers me as a high schooler with flexibility and learning. Technology is a gift for this!
It was interesting to hear about the differences between AM and FM radio.
This video was so cool and entertaining I love science!!!!
I love learning with Acellus.
Science Live is a combination of education and pure fun! I would like one Snoopy Award , please. (:
Love acellus!
Acellus is awesome I learn better than before ❤️
It’s awesome all the details and facts about radio waves and signals I didn’t know before.
Thank you for the best video of science live episode 286 radio waves this was the best and my favorite video in the world. The Acellus science live is the most relaxing thing to watch. I love science live because of r-51 he makes my day happy. Thank you for the best videos thank you keep up the good work sel aka science live. ❤❤❤❤
me to
Thank you for the video!
Cool
This Science Live this week was pretty interesting. Morse code is a great way to communicate, and a class in radio and aviation would be very cool. Also, the t-shirts are awesome! Thank you for making this Science Live this week.
Learning with Acellus is FUN!
I agree!
We did not know that height affects radio stations! -Skylar & Violet
I thought that the Omega Watch was super cool. And how they used Snoopy to make people feel better. And also Pajet Monet your my favorite 🥰
R51 is so funny!!
We love Acellus!
Thank you so much for creating Acellus! I really am learning a lot of amazing and helpful things!
science live is G.O.A.T
THE G.O.A.T IS RIGHT 🐐
I know right!
Great video can’t wait for the next one!
i love learning
I like the connection Dr. Joshua made between studying and going to the gym. Neuroplasticity and muscle strength.
I love learning with Acellus
love Acellus!
Radio waves!! I learned about a bunch of different waves in 8th grade.
I loved learning about NASA
I loved seeing the coral under a blue light … the colors were so vibrant and eye catching.
That was a great science live I loved learning about those watches I never thought about that!!
Acellus is great!!!
r51 was really funny today
I love learning about neuroplasticity..,. and right we never knew that a consistent study helped the brain absorb information!!!
I have never liked school but now with acellus I love school
Thank you Roger Billings for the interesting lesson!
One of my favorite science lives. So amazing.
Is it possible to get energy from radio waves?
i love learning with acellus and my favorite subject is language arts
I love acellus !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Are invisible waves always moving around us?
I love Acellus learning!
That is so neat to learn about the watch!
These are always so interesting! I love getting to learn something new from these every week!
I really enjoyed learning about how studying consistently helps with retention of information. I love how Acellus gold implements that concept with the daily goals. I am going to study everyday so I can score really high on my tests too!
How do hearing aids translate sound waves into something the deaf ear can understand?
Thank you for putting the shirts in the store, They are so awesome! My favorite is the one with the hydrogen car🚙! I also love the one with the picture of the earth in the shape of a heart🌎❤️. I am definitely going to save my gold and get one.👕
Acellus has helped me out so much, like i went from Cs in public school to all A’s from using Acellus. I just want to thank every teacher for helping me out and breaking things down so i can understand it so much better.
Acellus is awsome!
How are diamonds good semiconductors? Also ham radio class could be fun.
I always wondered what the difference between FM and AM radio was.
I enjoyed learning about the different forms of communication, especially the Morse Code.
I like how the courses are broken down into steps. It makes things much easier.
I am wondering how far radio waves travel into space, and do they ever end?
Can radio waves travel through space without needing a medium like air?
Starting Acellus was definitely the best decision I’ve ever made!!
Intriguing to hear how lasers can play so many roles
You should definitely have a radio class, that would be awesome! We got out our AM/FM radio and walkie talkies to learn even more about radio waves! Great information this week 🙂
Radio Waves are super cool
What does S.O.S. mean i heard that submariners used it
This live was incredible as always, see you next week 👋
LOVE ACELLUS!
I’ve learned so much watching the science live videos each week.
A morse code or radio course on Acellus would be awesome! I think I would enjoy it and many others would too. Thanks for another great science live!
I enjoy watching the weekly videos with my mom!
Really cool, I’ve always been fascinated by radio waves and how they travel. I wonder how a lot of related things work
I didn’t know how important studying was with retaining information. I wonder what other things help with retaining information.
learning on acellus has been such a help compared to my previous curriculum! thank you guys
I didn’t know you could cool things down with lasers
This episode was very informative!! I loved learning about heat waves and learning new stuff every week!! Thank you Acellus!
thank you guys for all your hard work to make this happen!!!!:)
I want ham radio and pilot courses. That sounds like fun.
I love watching science live! I learn so much, and often times even get a laugh.
I never knew that a consistant study helped the brain obsorb information!!!!!
How long did the Omega watch testing take to fully complete?
I love learning with acellus!
wow I love this episode
Me too! It’s a TON of fun to do it. I woud say Acellus is an opportunity of a Life time!!! Thank you Acellus For an AMAZING schooling program!
I love acellus academy
acelleus is a amazing home school its so easy to use
me too
Me too, I love learning here.
Same!!
I never knew that a consistant study helped the brain obsorb information
We have the same thing in our mind…👍👍👍
I LIKE to Learn At school and I like to learn At acellus
thats cool!
Do hidden currents ever travel underground?
I really enjoy Acellus I’m watching these videos I learned new and exciting things all the time and it’s awesome.
I loved learning about neuroplasticity!
I love learning with Acellus
So do I
R51 is so funny
I love watching science live it is the highlight of my week!
I love learning with Acellus and social studies is my favorite subject.
Same!!! Social studies is my favorite course too!
Why do we research more things about space than the ocean?
Because they have figured out how to keep oxygen in for space but they still can’t deal with the pressure from the ocean.But I had also had that question at one point.
Because there is inevitably more to learn about space than there is the ocean.
I think it’s because we haven’t invented a submarine that can go very deep without without being crushed
It’s crazy how many things that impact us so much exist that we just can’t see with the bare human eye.
Love these lives
I love these videos every week, I cant wait for the next one!
I loved R51’s segment this week, it was really funny! My dad is really into ham radios, I bet he would’ve loved this episode.
I love this episode! It’s so interesting.
do they still make the omega watch?
yes the do. They are still worn today.
I looked up the prices of them and they’re really expensive
