I think it is fascinating how radio waves enable you to hear music.
I never would have thought that a wrist watch would save astronaut lives. Way to go, Omega!
Thank you Acellus! The radio waves are very cool, would you ever be able to see the radio waves?
These are great tips for studying, i will apply these!
This episode was awesome! I think it’d be really cool if Acellus had more courses dedicated to learning more about marine life
I never knew about HAM radio, this is cool!
Learning about radio waves and how they are caused is really interesting. Thank You so much for this video.
Thank you for doing these! We just traveled through Kansas City and were excited to see the Acellus buildings
This has always been fascinating to me. Just the thought of how far radio waves can travel alone!
I think a hand radio class would be awesome!
Why does studying for short hard times help you learn more
pretty cool about the watch testing. never thought about such a small thing being such a big deal for space
I love Acellus. Thank you for the information provided through these videos everyday.
I really enjoyed learning about radio waves! It’s very interesting
I want to try living in space. I wonder if that will happen in my lifetime
I am glad we have cell phones and not telegraph
My great grandfather used HAM RAIDO.
I am so excited to see all of the shirts. And I would also be interested in the morse code class, it sounds wonderful!
If you are considering to put a HAM radio thing in Acellus, than I would rather have it as an activity. My idea of the activity would be this: there is a “cheat” sheet where it transcribes morse code letters into English letters (e.g. O= −•−•). The objective of the activity would be trying to translate morse code into English.
I feel like recieving a long morse code message would be difficult, you would really need to be quick witted
I didn’t know coral wasn’t a rock
That’s cool about the radio waves! I actually have my own radio!
Lizard robot beep boop beep
It’s funny that an award is named after Snoopy From the Peanuts!😆
Vulcanized rubber was discovered by accident too!
Never knew the part the omega watches had in saving the Apollo mission.
Science live is so much fun
It’s is crazy to think that coral is a living creature, and that there is millions of species of them, including more undiscovered. Also how did they figure out that they can use lasers to cool stuff extremely low, going almost absolute zero and not damage the object?
The ocean is easily the most interesting part of our planet. So many intriguing and unknown things that still confuse scientists to this day. So cool.
How does coral form, why does it have so many colors, and is it alive. If anyone knows if you can let me know.
I love the section about the astronaut watches. So cool to think something that seems so small was so important and had to go through so many tests
I find it interesting that hydrogen can power so many things but also not be harmful to the world
Science Live is a fun way to learn!
I liked the sponge bob reference!
The watch facts were cool. My mom liked learning about the Snoopy award. She loves Snoopy!
Thank you Acellus
can radio waves be blocked by something standing in their way
I think Morse Code is such a cool way to communicate. Id love to learn it.
i would be intrested in a ham radio course or activity!! 😀
Could there ever be a hydrogen powered spaceship?
Its amazing how with radio waves, we can hear things from all over the world.
A Morse code class would be really cool!
I never know that the radio stations had to do with radio waves am and fm*
wow I didn’t know that NASA had that many Apollo missions,
Maybe I should try studying everyday instead of cramming before a test. It would probably help me retain more information.
I would really like a morse code class, I think it would be fun. If i can ask as well for some more biology classes, or stem classes.
loved this episode!
These lives are always so interesting. I’ve realized through them that I really enjoy technology and I’m considering going into that direction.
I like the part about the astronaut they had to get to earth before they ran out of oxygen the story was amazing
Thank you for doing these weekly videos acellus!
That is cool how you can adjust your daily goals it helps
The snoopy award story was neat.
science is my favorite subject
I have always been interested in radio waves. It blows my mind how far they can travel.
I always like the jokes at the beginning.
I liked listening about NASA and the watches!
Great show!
This episode was so cool!
I am interested in the ham operator class and app if one is created.
This might be the best science live!
Radio waves are awesome!I can’t believe they were discovered because of a chocolate bar!
Thank you for the engaging educational opportunities! Learning about the Omega watches and seeing Dr. Billings on the radio tower was incredible.
Thank you for an interesting video! My family loves watching these together.
I think radio waves are very interesting. It’s amazing how they were discovered.
I’m so glad the coral reef was mentioned I love learning about it!
I really like the topic of radio waves. I wonder if we can focus more on light waves/particles next time. All in all, amazing video this week!
Thank you DrB for helping us.
I like these science videos, they aren’t like public school. Its fun to learn this way
The video was fascinating! I loved learning about the radio,I wonder how many people still listen to the radio nowadays!!.Great Content!.
I love learning about the ocean. There is so much stuff we dont know about the ocean and so much more to discover.
I didnt know coral was even able to be fluorescent.
The aviation classes sound fun so I vote for aviation classes.
Impressive how Omega was able to create such a watch!
You guys should definitely make an ham radio class it would be amazing.
How old were you when you began learning Morse code?
I thought the radio wave talk was quite interesting as I was looking into getting a walkie talkie.
Do radio waves ever disappear, or do they keep traveling forever?
Morse code was a really cool invention. I would love to learn it!
I want one of the Omega watches!!!
The Omega watch is so cool!
What are some other tricks for memorizing Morse code?
Radio waves are amazing! There are MANY different uses for them.
The concept of radio waves are really intriguing to me, it’s crazy how they were discovered!
How strong would a radio signal have to be to make currents underwater?
This video was interesting, I wrote so many notes!
I would be interested in a Ham radio class
My dad says that ham radio is a great backup communication device in case of natural disasters. He says that during some natural disasters, the normal radio, TV, and phone services go down, and if you can use a ham radio, you can get help. Is that true?
Study hard, work hard, learn hard, and you could WIN
I repeatedly get to love the Science Live videos because they always have the trademark intro song, and start with Dr. Joseph telling us a science news and a joke.
This has been one of my favorite episodes so far!!!
Thank you Acellus for making those Science Live episodes every week! I love it!
Another informative science live! Always interesting!
I love how colorful coral is
The story about the wrist watch is so cool. I would love to learn more about them going to the moon.
I would love a pilot class!
The Omega watch was really cool
The fact that something like coral is alive is truly amazing. One of the many wonders of the world.
It’s crazy to think that if those people missed the booster by a millisecond they had the risk of not coming back I’m happy they made it back but it shows on how important time is.
it is crazy to to think that those watches saved those people’s lives and that is a very scary fact that if they missed it by a second they wouldn’t have been able to get back.
I really enjoyed this live, and a course on ham radio would be incredible!
It is interesting to learn about lasers being able to cool things down, as it’s nothing like what you’d likely first imagine when thinking of lasers. It is also cool to learn about coral since I’ve only ever heard and gotten basic explanation of what it is, not in any slight depth or having seen it. Science Lives are really fascinating because they always have things to go over that you hadn’t known before.
This was a fun episode. I really enjoyed learning about radio waves. See you next week!
My question is can the laser be designed small enough to put in things such as phones and tablets to help cool down the microchips?
The coral reef system looks really pretty with all of the colors.
This week’s Science Live was great, especially when we learned about Omega’s amazing contribution to the Apollo missions. Thank you, Dr. Roger Billings, for another awesome episode of Science Live.
thank you for taking time to create such educational lives
The Dr. Tobias segment about NASA innovating watches for astronauts was very interesting.
It’s not a question but I hope you can thank Tobias for being so awesome all the time! On behalf of me and all the Acellus learners, thank you Acellus team!
Always a pleasure to learn more about the world.
Never knew coral was alive, I’m glad I learned something new!! Thank you Accelus.
Great class, I would be interest in learning how to fly a helicopter. Thank you!
Please make a lesson about Morse code!
Its crazy we can see the sun charge up the atmosphere
It said there was an error with my last comment so here’s my resubmission. I was really impressed by the watch story, it was fascinating how it survived so many trials and then made it to the moon on Apollo 11.
I would love to learn more about the moon
*I love this so educational and uplifting
Those coral are very colorful, That makes me wanna go diving.
*I loved this episode of radio waves. I would like to learn more about Morse code,
This episode was awesome! Thank you Acellus!
Is that lizard R51 found actually from Mars?
This episode helped me understand radio waves much better.
I liked the part when they told us the fact that coral is alive , and when he said that it BLEW MY MIND!!!!!
I think having a pilot course would be really nice and give kids who are interested in that the opportunity to learn more about becoming a pilot.
Radio waves are very interesting and also morse code
Loved this episode can’t wait for the next one.
Tobias is one of my all-time favorites. He’s amusing and makes educational facts interesting (I mean almost everyone does). But, just his jokes. For example: “Today we’re talking about one of the most important invention from China…” *photo of a fortune cookie shows up* “No! I’m not talking about the fortune cookie!!!” L.O.L.
literally the best thing to watch!!
I had no idea that coral was alive!!! Hopefully one day i get to go see some for myself.
What a cool episode! so cool to learn about radio waves, looking forward to next week.
When did radio stations become a thing so that we could listen to music?
Radio waves are cool super cool!!
I think a course on flying planes/helicopters would be great! My uncle has a helicopter and a pilots license, and it would be so cool if one day I could fly it!
What is the main difference between AM and FM radio waves?
Does NASA still use Omega watches? What new features do they have?
This is an interesting episode!
I appreciate you making these videos! I love them! Coral reefs are really important in my opinion, coral is a living thing, it’s not just an object to anyone who never knew coral is alive.
Taking a watch to the moon is so neat!
I love science live so much!!! I learn something new every time I watch it.
During hurricane Hellen I had to learn how to use a radio if we got lost.
I love learning something new every week. Thank you Acellus.
Thank you! I really enjoyed this Science Live episode!
Radio waves are interesting
The explanation about how radio waves travel through space was super interesting, crazy how something invisible can connect the whole world.
The only schooling that keeps my attention span.
How expensive was the Omega speed watch?
I like how Tobias explained how they made many tests of the Omega watch, and saw it was successful enough to be sent to space to see time correctly.
How much can our brain hold?
I would like to learn more about radio waves and how they work and operate. That’s would be a very great class!
I would LOVE to see a Morse code class! I’d enroll immediately! Great video, Acellus.
Coral is so colorful! I had no idea how many colors coral could be.
It’s interesting to know how important watches are to astronauts to keep track of time on earth.
How old was Roger Billings when he learned morse code.
I did not know that coral is alive. That is neat!
On a Morse code can you only use certain letters or can you use the whole alphabet?
Does NASA still use the OMEGA watch to this day?
I thought coral was really interesting!
R51 is so funny! And adorable
I had no idea that coral was actually alive!! that is incredible!
I would like to have Acellus have a radio channel learning experience so i can learn morse code.
Loved this one by far! Thanks Acellus.
I think morse code is very fascinating. The way a series of beeps can be translated into actual letters and words is so cool to my brain. Definitely something worth looking into to learn!
I love aviation, I cant wait for the aviation class
Very interesting. Glad to have these to watch so often, thank you acellus. 🙂
Science is really cool
It is fascinating to hear about the progress in solving issues with the watches.
super cool as always!
Both a Hand Radio and Aviation class sounds quite cool
Did you know both are used in flight
I could literally hear the “a few moments later” lol
Science live is awesome!
I really like the information about the omega watch. I had no idea snoopy was a part of the mission.
I would actually absolutely love to enroll on a piloting class!
I never knew that you needed a watch for space. A Morse code class would be interesting.
I would love to see the northern lights closer.
It would be nice if there was a Morse code course.
I liked the moon watch
