I love science live so much! It teaches me so much and it’s very fun to watch also.
I absolutely loved the HAM radio segment!
We went to NASA and we learned about all the food they eat in space, but I didn’t know about the watch. That’s cool!
Love y’all’s video’s lol!!!
Radio waves are cool to learn about. Mr. Billings is a great and smart guy.
That was a great lesson! Thank you so much DrB
Thank you for the most amazing lesson Dr B
This live has been my favorite I think so far I love how the radio waves move and work.
My cousin and I live a few miles apart so we use CB radios to talk sometimes. It’s so fun!
I think the coral and dyes were amazing! The coral was out of the park! The dyes were so florescent, and they were so bright!
I love science live. Morse code is so cool
The coral and dyes are amazing under the black and blue lights! Could those things be used on clothes or items if so then could they also be used in science and medical experiments?
I agree with Dr. Joshua on studying daily and not have a day or a week in between studying sessions I also really want Tod edemen to have a class on conspiracy and I love science live!
If two radio waves perfectly cancel each other, where does the energy go?
I think it would be fun to own and to operate a ham radio.
I love these lives. They are the highlight of my week
I thought it was interesting that the the Speedmaster Omega, was able to accomplish such difficult tasks and still stand.
Dr. Roger Billings science live videos have been very interesting to watch.
Science live rocks!! It’s always fun watching and listening to all the interesting facts and theorys.
I love Science Live.💙 I love Dr. Roger Billings story about radio waves. I would take the course about radio waves!:)
I never know that, do do do means “S” till just now
I WANT A SNOOPY WATCH. HYDROGEN IS VERY INTERESTING. I LOVE LASERS AND WANT TO WORK FOR NASA.
The watches in space being the only way to tell time after the failure and needing it to be accurate to make it back to Earth would be scary. Good thing they’re professionals.
Thank you so much for another wonderful video! The amazing Intel Tobias shared on the watch was extremely interesting along with what Dr. B shared regarding the northern lights! Wow! That’s amazing! And, the insight Dr. B shared on radio waves is Magnificent. Thank you!
SCIENCE LIVE IS THE BEST I LOVE IT
I limed the part where he talked about Ham Radio. I bring this up because my dad and I are interested in Ham radio
I love the Northen lights and have seen them a few times. I also love the maroon sweater and the necklace.
How would you communicate with a quantum computer in space?
When did they discover that you can use lasers to cool things rather than heat them up?
That’s so cool! I didn’t know that coral could be fluorescent.
I have always wanted to learn Morse code. I agree that it would be interesting to have a class option for students interested in becoming a pilot. Thank you for sharing the shirt designs too—they look amazing!
Thank you for always listening to your students ( new class ideas) . We appreciate you!
how long does it take to learn Morse code
It would be so interesting to learn morse code.
I have always wanted to be an AIR Force pilot or a National Geographic Photographer.
I think a Piloting class would be an amazing course. Over.
My favorite part about the video was when they where talking about Apollo 11 and NASA and the omega watch because buzz aldrin and Neil armstrong wore the Omega watch and that is pretty cool because I did not know that and I love space.
I just love watching Roger Billings, hes so smart
I saw the northern lights in Wyoming aswell.
I’m glad you showed us what SOS is in Morse code, I hope we’ll remember it if we need it someday.
I loved this live, I love learning about radio waves.
this show is so fun to watch every week
The flourescent colors look cool
Radios are always a facinating subject. From how control centers work, to how mobile radios pick up signals, and even the science behind actual radio waves themselves, I always seem to learn something new every time I’m taught about radios. I didn’t know that radio tower’s hights were specially calibrated to the length of radio waves they send out. I wonder if I could learn morse code?
Yes on the aviation courses and yes on the radio and morse code courses! Acellus just keeps getting better and better!
I liked learning about the moon❣️
The coral looks so beautiful! I love Science Live!
I love science live 😎
Do the lasers just go forever into space? Or do they stop at a certain point.
I would like to learn morse code.
I love the ham radio idea!
I didn’t know that the radio waves are created from such a small device
why does the gold shop close and how do you purchase items from it when its closed
How do we know space is cold?
I believe a radio class would be wonderful to partake in!
Learning about Radio Waves was super interesting, plus, R-51 making “contact” with Mars was hilarious. I am looking forward to future Science Live videos.
I love Science Live!
This live has been the best so far! I think its so cool how radio waves works
I would Love a ham radio class and a pilot class!
This was one of the funnies Science lives I’ve ever watched, learning about Radio waves was awesome. Plus, R-51 making “contact” with Mars was hilarious! I’m looking forward to upcoming Science Live videos.
The fluorescent coral is very interesting.
The Morse code class would be awesome
Does the watch work if it gets wet?
Neuroplasticity is very intriguing and i am definitely doing more research on it.
Are diamonds good for semiconductors?
My dad works with radio waves in his cell tower job.
I love Science Live
Those shirts came out awesome.
Thank you for sharing, I love Science Live
Do lasers just stop once they reach space or do they countinue forever?
I have always been into morse code, its so fascinating how one can communicate in ways like that!
I love watching these every Wednesday!
I loved the story about the watch!
I love R 51
Where I live I was able to see the northern lights, but only through the phone. It was hard to see to the naked eye.
Im in Tennessee, did anyone else in Tennessee see the northern lights? I didn’t see them. that’s a good idea with the phone! I wouldn’t have thought of that, ill have to try that next time.
Great science live!
I love these science lives so much, Dr. Joseph is so educated.
If you make a pilot course I would be very interested I have a few dream jobs and one of them is being a pilot.
Tobias is so funny!
this is starting to be my favorite part of Acellus!!
My mom is a Ham Operator and she is teaching me about radios!
Morse code is so intresting!!
I love these weekly science lives! They bring joy to my week!
I’m pretty sure I’m going to space one day.
The coral looks so cool!
Morse code is very intereting! I <3 science!
I found that pretty interesting that when you put these certain colors in light that they glow! It’s vert interesting to be able to see the beauty within nature also just from regular light!
This was a cool science live!
I love you guys so much, You all are my school family, and make science live enjoyable to watch! and you all are so funny, and I love learning things when I join science live
It was really cool to learn about the Snoop watches!
Yes! I would like a pilot Acellus course!
I loved this science live! Looking forward to next weeks live.
how do they know when you are interrupting the other station?
R-51 is so funny!
I really wish I could’ve seen those northern lights! Sadly, despite living in Illinois, just a little south of Chicago, I was unable to see them.
I love Science Live so much! Keeps me updated in the world!
That is awesome that Omega got the Silver Snoopy award for their watch helping the astronauts!
Can people still get the snoopy reward?
This was my favorite video yet! HAM radio is so cool!!!
The steps for every subject is very helpful.
I love r-51
Great science live, keep inspiring young generations to come! Loved the lived today.
I liked learning about the watch that went to space!!!
I would love if we got a helicopter program, thank you.
I took pictures of the Northern Lights here in Nebraska!
I LOVE THE PART WITH R51
How cool to learn about the radio waves! and the picture of Dr. Roger Billings???
It’s incredible how something as small as a wrist watch could save countless lives and be apart of one of the most extraordinary, mind blowing, life changing projects the world has ever known. Our moon is seen by all of us on this planet, and with NASA’s help, we were able to discover much more than what the surface our eyes meet. But not just NASA, also Omega. Naming the prestige award granted for assisting the astronauts Snoopy is also adorable. I’m sure it was literally the most terrifying thing to hear only 14 seconds could mean you live or die. So thank you to those investors and scientists who created an object that could savor the time, withstand multiple unnatural conditions, and most importantly, keep something as precious as our human lives safer. 🙂↕️
Dr. John, your part is always my favorite! We have corals in our fishtank
Thank you for another great live! I would love to see the northern lights in person some day.
R-51 is the funniest! He is so funny when he does “his” experiments that “he” made!
The spacesuits looked really cool! I’m from Texas.
Thank you Dr. Roger Billings for another wonderful video
I couldn’t see the northern lights from where i was from 🙁
Science Live and radio waves rule!
I looked at the northern lights.
You should definitely do a ham radio and pilots course
R 51s THE BEST OF THEM ALL
I learned coral can make different florescent colors.
How does Mr. Roger know so much about so many subjects? How does he remember everything he’s learned throughout life
These videos are so fun to watch. Thanks Dr. Billings.
Studying everyday will help me succeed.
It’s nice that you can see when you will possibly be done with your class.
In Morse code, is it only used in English? Or is there alternative versions for other languages?
I love science live!
Didn’t get to see any northern lights unfortunately
Enjoyed this weeks science live!
Didn’t expect a watch to save astronauts, love the shirts, ham radio could be fun, and pilot classes sound great!
I thought it was really cool that Dr. Billings knew almost all the letters in Morse code.
It was really cool seeing Dr. Billings old radio tower.
I didn’t know astronauts wear watches.
Acellus headquarters is in kansas right?
Very cool!! Favorite science live so far 🙂
I LOVE SCIENCE LIVE
Thank you for teaching me about how lazers are able to cool different objects; I never would have guessed!
Our son cannot type his own comments yet, but he LOVES the Area 51 segments! Thank you for another great Science Live! I as a parent enjoy listening as well!
I liked when Dr. Billings was talking about Buzz Aldrin because that was very cool
R-51, you crack me up!!
I would love to try a ham radio class! It seems fun and interesting
I love science because of Dr Roger Billings
Morse code is so interesting and I will be learning it soon. I love science live!!
Is it possible for a radio wave broadcast to reach the entire Earth?
I’ve always wanted to see the northern lights but every time I’m supposed to see them I’m never able to! I want to know more about how and why they appear when they do?
i didnt know the differences between am and fm radio waves
How long did it take you to learn Morse code?
Science live is so fun. Much love from middle TN!
I like when the toy lizard was crawling up the walls.
Are there any other gadgets scientists plan to make astronauts use in space?
Radio waves are interesting
How does the frequency and wavelength of a radio wave determine it’s properties and uses?
Is Morse code often used in different languages?
What other watches did the Omega company design?
I’ve learned so much about AM and FM. Thanks Acellus
yesterday the northern lights were out where my house is but we are out of town and I did not get to see them. I think it was really cool to see pictures of.
Its so interesting how lasers don’t just make things hot !
I remember learning SOS in morse code when I was in elementary school and I thought it was the coolest thing ever. I was also wondering how someone comes up with something like morse code, just thinking about it is so interesting!
Can we do more contests like the t shirt designing one?
Is Morse code still used a lot?
I love your jokes!
How do radio waves travel and interact with different materials?
i like r.51 he is funny.
I liked this Science Live
Crazy how much every detail is important in space.
What other watches were designed by the Omega company?
I think it is cool when they talk about radio wave traveling across water at 600mph which couses earthquakes or tunamies.
I love science live so much!
How many different types of watches can you buy from the company Omega?
Thank you for taking the time to teach us interesting topics.
I love these lives
Thank you! I love these videos. I tried to see the northern lights from my house but I couldn’t.
I would like a Morse Code Acellus class. That would be fun 👍🏽 <———my hand
Science is the best!!!
can you talk to japan?
I SAW THE Northern LIGHTS!!!!!!!!!!!!!!!! AND I LIVE IN MONTANA!!!!! I WILL LOVE RAIDO
…. . .-.. .-.. —! (Hello in Morse Code!)
I think an acellus class that teaches Morse code would be fun.
