I didn’t think Apollo 13 was saved by wrist watches… I should probably watch the movie to see if the movie is accurate
I would have never assumed that it was possible to cool anything with a laser. I think that’s an awesome discovery and will be very beneficial in the future.
What is the average amount of steps I should be doing each day in every subject?
My friend is a hamm radio operator. He let us talk to people in Brazil on the hamm radio kids day. It was cool.
I LOVE Science Live!!!!!!!
I LOOOOOOOOOOOOOOOOOOOOOOOVE R-51
Radio waves are interesting to learn about.
Acellus is the best!
I love Science Live so much! I think I will never stop watching Science Live.
Acellus is better than my old school
!
I am going to make my brothers watch this episode since it talks about how to study. They like to wait until right before a test. I liked this episode, it was interesting.
I loved the story about the Omega watches that were made for race car drivers and used for astronauts. I now definitely need a Snoopy watch!
I enjoyed this episode of science live and loved R51 he is always so funny
Love Acellus so much!
Acellus helps me a lot. I feel I understand my studies better.
Really enjoyed watching my first Science Live!
These science lives are very interesting and wonderful!!!
I like that you can use morse code to communicate.
Thank you for doing Science Live!!
I had no idea that lasers could be cold….that’s cool.
The lizard part made me laugh so much
It is interesting hearing about quantum computers after I’ve seen them in some movies already!!
I love Acellus I am learing so much !!!!!!!!!!
The Snoopy award is so cute. I make some notes in morse code.
The science lives are really interesting, thank you for doing them.
I have always been interested in watches, and vintage watches in particular, but I have always had a special place for Omega watches because they’re cheaper than luxury watches, and they have a simplistic look that Omega has masterfully perfected.
And they are extremely practical.
Therefore, this was, as always, a very interesting Science Live.
Josua.
I never knew they took a watch to space! That’s cool.
that’s was so cool hearing about the watches.
I love this school and the things we get to learn!
I LOVE THIS
Why did all the other watches stop working in the thermal vaccum? Also, I think a radio and pilot class would be great!
Great video! Thank you acellus team!
Radio waves are one of the most important forms of communication between humans.
The segment regarding the lazers was really cool! I thought it was amazing how they used lazers to cool quantum computers!
The science live videos are always so interesting and teach us new things!
I have not learned much about Apollo 13. I want to look into it more. It’s cool they had to depend on their watches to get home.
Acellus is amazing. The presenters gave me a lot of useful information.
We just started hearing about Morse code in my Social Studies Class! Very neat!
I love Acellus its a pretty good learning/school app
Hello My name is Landon Creadon and I always learned new things from every single science live video and the last 5 minutes of today’s science live video was so funny to watch before the science live video was over and other things too.
who was roger billings” biggest inspiration while he was pursuing his profession.
My Aunt had a short wave radio, I thought it was fascinating. She could talk to people from all over the world. I think Radio is amazing. I also think Acellus is one of the best learning programs ever.
I really love all the teachers who do Science Live.
Acellus has taught me so many new things!
Apollo 13 is awesome!
It is amazing how even if something does not work you, if you keep trying it will work eventually.
It is amazing how every step takes you to something new
I enjoy Acellus a lot!
I enjoy the science lives!
Really loved and amazed how a watch saved lives!
Acellus is awsome
I absolutely love Acellus!
Awesome sauce! I love science live!
We follow the missions for space since we’re in Florida and can see rocket launches from our backyard! They’re fun to watch, especially when it’s dark. I’m excited about hopefully getting someone back to the moon!
Radio waves are so cool!
It’s fascinating how intricate radio waves and the technology that uses them is. Thank you for the great episode!
Classes on radio and aviation would be awesome! I know it wasn’t discussed in this video but would it ever be considered to add a photography class?
R-51 is so coooollll! I l love you!
I love Acellus!!
Amazing!
Acellus was a huge change for me since I struggled so much with schoolwork on paper! And Acellus Gold is even cooler 🙂
I really like how Snoopy was included as an award
I love Acellus
I LOVE ACELLUS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It would be amazing to have aviation courses and helicopter courses!
The first watch to make it to the moon.
I love how these these are educational but still fun to watch I love them!
I absolutely love learning! Acellus and the Science LIVE makes it so fun. Radio Waves are so cool to learn about.
I really love watching Science LIVE and learning through Acellus!
Great live!
Love learning about lazers. Thank you Acellus.
I loved learning about the Omega speed master watch that was used during the moon landing.
I love these videos they teach me so many things
Having consistent schedule sounds like a really interesting idea to do, I’ll definitely try to do that.
*I love how Dr John has new inventions to tell us about every week!!
I love Science with Acellus!
Science is great!
I love these videos so much they make me feel smarter
The Omega watch was so important for Apollo 13. It’s also cool that they were able to wear it on the moon.
I 100% truthfully love science live, and definitely watch every new episode.
Do you think there is a frequency that we haven’t discovered yet?
These science lives are my favorite!
I lovee how Radio waves were explained and what they were, how they travel, and how we use them for things like communication and aviation. It was very understandable and an interesting topic to learn about.
I am so excited to be doing Acellus I love doing online school.
how do radio waves travel through the atmosphere, and what factors can cause them to weaken or change direction before they reach a receiver?
Every Science Live provides so much useful information.
I love watching science live, there’s so much stuff I never knew about.
I love what yall do!
yes, me too TREVOR I couldn’t be more thankful !!!!
I enjoy watching science live!
Neuroplasticity is interesting and I’ve learned that consistent study time in small chunks of time and spacing study time helps improving your ability to retain information. One way at Acellus is to use the daily goals set in each of your classes.
Thank you guys for this Science Live I appreciate it.
Science Live is so cool!!!
I love all of the tshirts!
Radio waves are super interesting.
I love watching Science Live. It was very interesting this week when it talked about how the watches helped Appollo 13 with their mission to get back to Earth.
It was really interesting learning about radio waves.
I love the jokes on Science Live, they always make me laugh. Don’t have a gig yet……so funny! Who knew that wrist watches were a part of an astronaut’s suit? I sure didn’t! This was very interesting to learn about. Thanks for all you guys do to make Science Live so fun and educational!!
I love Acellus!!!
Never would’ve thought lasers would be used to cool things.
It’s really cool how radio waves work!
How long did it take to get to the moon and back?
I’m grateful for Acellus!
Thank you for having Acellus as an option for online school. I am happier than I was in in person school and my grades are so much better. I love Acellus!
It’s crazy how far technology has come in just the past 50 years.
bioluminescence is cool
i love Acellus lives
I think a Pilot program would be cool.
I think we can subconsciously hear radio waves because I’ve hummed a song only to turn on the radio with it playing that song.
Thank you so much for the amazing science live lessons. They are fascinating!
My grandfather worked in radio his whole life! He loved it!
Why are AM radio stations less common and have less radio frequency?
Area 51 is funny. I vote yes to radio and pilot classes.
When I saw the Snoopy award given to the astronauts, I thought it was so cute!
I really enjoy these weekly live videos! Thank you
Glad I found a way add a comment. Tobias is my favorite to listen to.
Wow thats a really big antena, its crazy how smaller they have gotten but still work the same.
I vote yes to ham radio and pilot helicopter classes.
How do radio waves carry complex information like music or digital data?
Awesome live! Can’t wait for this week!
I love watching science live!!!!!!!
How does someone manage a radio wave to broadcast at a certain station number?
Acellus teach so many new things didn’t know it helps me so much!!
It’s fun to see Science Live.
R 51 is so funny.
I am so thankful that my mom is letting me attend Acellus. I am doing better in school. Thank you.
I like Acellus.
This has been my favorite so far!
R51 I have that same Gecko!
What are the requirements to get a radio license?
I don’t know how people are so smart to come up with things like morse code and radio waves!
I look forward to Science LIVE every week!
I thought this was pretty interesting, i especially love learning about how certain things work. Can’t wait for next week!
What is the lowest frequency you can get to and what is the highest frequency you can get to?
Does switching to a different walkie talkie channel change the wavelength or frequency and that’s why you only hear it if you’re on the same channel?
learned about the omega watch that is part of NASA’s spacesuit and all about am/fm radio waves in ham radio.
Thank you roger billings
I love this one wow!!!!
My uncle used to spend a lot of time talking to people around the world on his hand radio.
I love science lives!!!
Acellus is fun! I love my teachers
We are WATCHING and WAVING hello from here 😀 ⌚️📡
I love r 51
I learn so much better ever since i started acellus.
Does Acellus have sign language classes?
Do you think we have utilized Radio waves to their full potential?
how do lasers get hot?
I learn something new every time I watch this.
We could see the northern lights a little bit here too.
Interesting to hear how the watch had such an important effect on the Apollo mission!
loved the video! also I am excited for whoever got chosen for the shirt design, they did really well and were so creative, and little off topic, would you ever consider having a course that goes over stuff like this and one of the videos could be about learning mourse code? I thought it would be a interesting concept since lots of people still use Morse code and I thought it’d be a fun class.
Hi this is Maisie from West Virginia. It has to be very hard to memorize Morse code!
Science lives are the best I look forward to every week
These videos are truly the best part of my day when I want to windown and relax.
I loveeee these so much!!!!
I think it would be interesting to have a Morse Code class in Acellus, so I say “yes” to that idea!
Radio waves, are waves that have very long wave long wavelenghts to reach multiple places at once and is a type of electromagnet with lowest frequencies.
What does Apollo stand for?
what is the earliest grade you can participate in the science fair?
Why are some things florescent and some things not?
I LOVE ASL!!! I want more of that please!
I just love Acellus!!!
So are you gonna end up creating a Morse code class? I would take it!
I think space is cool. Can we get more on planets?
I love the fluorescent colors of the coral plants. I also learned that there are analog and digital radio waves.
I love this weeks video, thank you for what you do every Wednesday!
I’m new and I’m so excited to learn!
I love science live, and I will really like to do ham radio
What are some ways we use morse code today? Is it mostly for military?
aceullus is making learning fun again.
acellus is the best school program!!
Great episode explores many different things ! Can you still buy the omega watch that the astronauts wore in the missions?
Coral Reefs are so important and how amazing that they are flourescent!
Acellus is my fav!
Really cool stories on how the Lazer cools and the Omega watch on the moon.
I love the segment about Omega watches! I am from Switzerland and own an Omega watch. I never knew how helpful watches could be in space. But I have a question regarding that, when making the watch, did they ever have trouble with the glass and the pressure? Would the watch going to the moon have a special glass cover?
