Hey from florida!!!
Science live is the best
Acellus is cool
I never would have thought that lasers could be used to cool things down.
The Coral reef was so gorgeous
I didnβt even know what fluorescent actually meant until today so this was very cool to learn. Something as simple as a watch having possibly saved the lives of those astronauts is absolutely amazing to me. I wasnβt all that interested in radio until now but a course on radio seems like a lot of fun.
The ham radio lesson was interesting. My grandfather had a ham radio when my mom was a girl. He knew Morse code.
Hello from Florida!
The Omega Watches are amazing. I was not aware that astronauts wore watches in space. Omega should make a phone. Also, it was interesting to learn that lasers could not only heat, but cool as well.
Joining from SC!!
Mose code would be a interesting skill to learn.
The omega watch story was cool and interesting.
Radio waves are very interesting.
Morse code is an interesting form of communication.
These live streams are neat.
Itβs fun learning new things!
This was a great video, the morse code part was intersting.
Thanks for Science live!,
hi I am from Illinois and I am really excited for science liveπ
The consistent study suggestion was helpful. Thanks!
I think radio waves are very interesting and I liked learning about this.
Learning science is fun so I like learning new things.
Yea my mom says her brain has no space for my jokes.
Acellus is a awesome learning platform.
What age can a person take the ACT test?
Love acellus thanks for making learning fun!
Love science live!!!
My mom has to buy Thermal Compounds to put on our computers and Playstations to keep our systems cool or they overheat. I thought it was cool that they are thinking of putting the quantum computer in space because it is really cold because I know how important it is for our electronics, like computers, to not overheat and space would be perfect for that!
Learning about the watch was very interesting
Science is so awesome!
Black lights make things look cool. Like the hammer coral, it looks amazing.
So much to learn in 1 hour. Have came across alot of things that i hear or see and relate it to my science lives and what ive learned
I love how you explained what radio waves were, it helped me to understand it more.
its so cool how to coral looks! its like glowing!
Hello from Kentucky!
This was an awesome Science Live!
The whole appallo misson had so many steps to it, it’s a lot more complicated then it seems
Science lives actually help inform me on things I didnβt know about before at all*
I enjoyed Tobias and his overview of going to the moon!π
It was shocking how a watch could work in space. The omega watch saved Apollo 13 by being the only watch to tell him in space. It helped time the burner to 14 seconds because if they were off by even a single second then they would have missed earth. It was also neat to learn the lasers down only heat up objects but can cool them down as well. This live had a lot of information on it and I really liked it.
neuroplasticity improves with consistent studying and if you do a little bit everyday it improves the ability to retain more information and its easier and better than cramming study sessions for tests. the spacing affect is a better way of studying with small amounts of time everyday it helps your long term memory and keep information you are studying and learning.
The watch in space was cool
I love science live!!! Keep up the good work.
Thank you Dr.Billingβs for this episode, it was very interesting listening to how the radio work. The way you talk and explain everything is really great.
Science is amazing it’s very interesting I’m excited to hear more!
It’s so crazy and mind blowing how the brain works
I think that a Ham Radio class would be really cool. Also a helicopter class would be amazing!
I really enjoyed the story about the Apollo astronauts, and I want a ham radio.
Science Live is my favorite part of the week!
Hi from Alabama! A little late to this week’s Science Live, but I’ve been trying my best to fit them into my schedule and keep up with the weekly episodes.
r-51is sooo funny. because he is sooo silly!
It was really cool learning about the first watch that went to the moon, and how it saved all those astronauts.
Learning about the astronauts with their watches was so interesting!
I love science live!
thank you guys for everything I love acellus
does Omega still make the watches for Astronauts?
I appreciate the tip about studying. I will try to implement this in my schedule. π
ham radio class would be cool
I think its really cool how radio waves can travel through space moving at the speed of light
I enjoy learning different things each week. So much to learn. Thanks for telling us about Am and FM frequencies, never knew what they stood for.
I really like the florescent coral
My great grandfather used to work on aircraft radios in the navy. (if I remember correctly) I still have one of his old telegraph key.
I love Acellus!!
Omega has even made anniversary watches commemorating the 50th year of the Speedmaster going to the moon, and of the Silver Snoopy award, solidifying it as the moon watch.
My Mother loves to go snorkeling in the ocean on our vacations and admire the coral and the beautiful reef fish.
Iβve always wondered how a whole alphabet is deciphered by Morse code.
I did not know that astronauts wear watches in outer space, and that watches still work in outer space.
I believe radios are the beginning of what led to modern smartphones.
Dr. Billings was a very curious and motivated teen. I think spending time on a ham radio would be more fun than social media.
I loved learning about the space watch in Tobias segment!!πππ
Science is cool!
Why can radio waves travel through the vacuum of space but sound waves cannot?
The most fun part of science live is the r-51 show part!
Now I want to learn more about Apollo 13
I enjoyed learning about how lasers can be used to cool things down instead of just cutting things and heating things up. By far one of my favorite science live episodes!
Pretty cool to learn that without Morse Code our communication would not be the same.
Radio waves are awesome. My grandma used to listen to radio shows when she was a kid and didn’t have tv.
I love Science Live!
I think corals are really cool. All the different colors theyβre able to emit is fascinating!
We love science live. Yβall make it so fun.
I have always been interest in how Radio waves work, my mom wanted to be a radio host back in Alaska. And I was always intrigued how one station could air all over our city.
Coral is one of the coolest things in the ocean it’s so stunning especially when the fish swim through it.
Thank y’all for doing what you do in Science Live! It’s all so entertaining!
Iβve been wanting new courses and and Iβve always wanted to be a pilot itβs something Iβve wanting since I was like 10 I want to fly with the blue angels that was my dream.
Cool video!!! I never realized how much we use radio waves in our everyday lives! Thank so much for the video and educating us
Lazers being able to cool down chips and quantum computers are cool!
Some of our family friends were fortunate to see the norther lights. However, I couldnt see them where I live.
This has to be one of my favorite parts of Acellus!
Science Live should do a tour around the US and have their thing in different states so people from different parts of the country can attend.
Lasers being used to cool things down instead of heat them up is another really cool thing that science never fails to show us! π
Iβm actually kind of interested in learning more about Morse code.
I love science live!!! Also Morse code is really interesting!
I remember learning about the history of semiconductors and how technology has advanced. Thatβs exciting to see how new materials are being considered.
R-51 is awesome and funny!
Thank you for creating this program.
I think the coral is so cool. Itβs so incredibly interesting how radio waves work , how long was the discovery of radio waves to the creation of the first radio?
Are radio waves created by transmitters
It was cool learning how lasers can change the temperatures of objects based on their frequency!
Morse Code is so interesting! My sister and I printed out a Morse Code chart and are practicing!!
Morse code sounds really fun, i’m glad I was able to learn more about it through the live! I also think its really cool how the astronauts wore the watch to the moon, and how the watch was so well designed. I look forward to watching more of the lives in the future! Thank you Dr. Billings.
I want to learn Morse code
The information about neuroplasticity and cognitive overload was really interesting!
Great episode can’t wait for next weeks edition.
Science live is so informational
amazing episode 5 stars!!!
I think that a aviation class would be a great addition to acellus!
Now I know the difference between FM and AM waves.
Science Live is the best!
If, it’s possible to have a watch in space could they possibly make a functioning compass for space?
What was it about the design of the Omega watch that made it able to pass all the tests when none of the other watches could?
is it possible to create gold using science if we can create diamonds?
I’m so glad Science Live exists! It’s one of the highlights of my day!
what was the first semi conducter found by humans
I never really thought about what AM and FM meant on the radio station. I enjoyed this one
Another great science live! Thank you Acellus team!
Coral reefs are so interesting!
I’m so glad Science Live is a thing. It’s a highlight of my day!
What other things can Radio Waves be used for?
Here from Florida
Radio waves are always such an engaging topic! Learning about watches and coral, and so much more from all the other episodes!
I think Morse Code is really awsome.
Can we have that lizard in the school store? It’s so funny!
It was interesting that Apollo 13 had an explosion and had to shut down all time systems for power. It was also cool that they had to count to 14 to fire the burner and time the trajectory perfectly to land on earth safely.
I would like a class on HAM radios.
Always neat to learn more about the NASA programs!!!
Congratulations to the student who received a full-ride scholarship! That is an incredible accomplishment, and how cool that she completed her high school education through Acellus!
I thought it was amazing that something we canβt even see can go so far and help people talk to each other. I liked learning how HAM radios can send messages really far away, even without phones.
I always wondered what AM and FM stood for. Thank you for the explanation!
Its cool how lasers can cool jets.
science live is the best!
science lives are always my favorite!
Having one of your watches work in space is amazing marketing, and also the coral looked beautiful!
How do you say R in morse code.???
Can we learn more about the coral and other sea life? Itβs so beautiful and interesting!
I never knew about the omega watch and how it helped the astronautβs. Very neat.
This radio frequency stuff is very confusing. Loved the part about how we can all understand a rock being dropped into water and the ripples it makes. And wow, we have that same lizard from Mars how cool!!!
its crazy that technology like watches can work correctly in space.
Does Radio Waves go through phones?
History is my favorite subject, so learning about Morse code was fascinating!
Please make Morse code classes and HAM radio classes!
Why do some people think we never went to space?
Love π what we were learning today!!!
Thank you guys for the science lives! They are amazing!
I love Dr. Tobias
I liked seeing and learning abt the coral for sure and the apollo 13 story was interesting
Ham radios are so cool!
science is my favorite.
Thank you Acellus!
I enjoyed listening to the story of how Dr Billings got his radio tower π
That coral is so pretty, sad that we are loosing so much of it due to pollution. Listening to AM and FM radio is so different. I just learned that they encode sound. AM changes the signal amplitude and FM changes the frequency.
I loved the part where Dr Joshua talked about the gym and school!
r51 is so funny
I can learn so much from science live and I love Acellus ππππππππ©·
Loved hearing about Apollo 13 and telling time. We love learning about space. The Snoopy award is also very cool to hear about. Thank you for always talking about interesting topics that keep even the young students engaged.
i always look forward to wednesdays ! science is my favorite
Interesting lesson today! Would love to learn more about morse code in future classes!!
Are OMEGA watches still manufactured today to withstand the same standards it passed to be selected for astronaut use? Thatβs pretty incredible.
It is so cool how the Omega watch can work in space and on the moon! The accuracy of the watch definitely saved their lives by getting to earth on time and not getting burned. Also, the Snoopy award is such a cute name!
This episode of Science Live was AMAZING! π
love from Nevada!
How does a radio in a car pick up radio waves while moving 70 mph?
I’m so glad that we all have the opportunity to experience science live.
I liked this video because it has R-51
Science lives are awesome!!!
Acellus has helped me so much. Thank you
I think the Morse code part was really interesting, it would be a great idea to add it to Acellus as a class.
I found it so interesting the difference in FM and AM radio waves. As well as the different ways we can use wireless communication!
When was the first Radio station aired?
I am gonna learn Morse code just in case needed
R-51 is my favorite
I did not know that astronauts needed to wear watches in space, and that watches would work in outer space.
I would have thought that the pressure of space might have messed with the watchβs settings and functions, so this is impressive!
wow now I know why we are able to see the northern lights when we couldn’t before
Morse code sounds fun!!
Science is cool.
