My cousins grandfather did radio waves in the military and he loved to get old devices and take them apart and make new devices.
I like Dr. Tobias talking about the astronaut and the watch, and I liked learning about Charlie Brown and Snoopy!
science live is soooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo cool
Amazing explanation! I never realized how much science goes into something as ‘invisible’ as radio waves. Loved this episode!
Morse code was quite interesting, as they just made a machine making a bunch of dots and lines, and they used it to communicate.
I Love Science Live🔬
A ham radio license course would be amazing. Please make that available.
The ability for lasers to provide heat is one thing but for coldness being provided is just shocking to me.
Yes, I would be greatly interested in a ham radio operator course. That would be awesome!
I really liked the show! 😀
I love watching science live!
I love Acellus !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I really enjoyed learning about the omega speed master it looks like an awesome watch.
Lasers are amazing!!!
I didn’t know that black light couldn’t be seen.
I love Acellus!!!!!!!!!!
I love watching the live science videos. I learning something new, each time!
I’m so intrigued! Where can I learn more about the Apollo 13?
I like how they have so many different segments on Science Live.
How old were you in the picture when you climbed the tower.
We love R51!!
I loved this episode, thanks so much for all the work everyone at Acellus does!
Have a great week!
I really enjoyed learning about the way radio waves are created and how they move. Thank You Acellus for another wonderful Science Live!
I would like to meet Dr Billings. He’s a genius!😁
I think learning to fly would be a cool course.
One of the best science lives yet!
The corals on the bottom of the ocean are so pretty. That is so cool that they are fluorescent.
My papa had ham radios, he said he used to wait until nighttime and chat to people in other countries back before the internet made things like that possible. He said he had to have a license or something in order to be able to talk to people.
new being here and I’m already invested in this
You could see the Auroras over the mountains in Colorado and it was very pretty.
My favorite part was when R51 was using a ham radio to communicate with Mars.
What is the distance for the hand radio
If we could see radio waves with our eyes, what would they look like?
Thank you Dr. Billings!
That’s so cool!
My Mama has a FM radio app on her phone. Is it using radio waves or wifi?
Usually phone radio apps are wifi, but you would need to research that specific app.
I always learn something new watching these videos! thank you
I love Acellus ! Great learning experience!
Thank you for doing this for us. I would love a radio class
How small can a laser get?
How many working quantum computers exist in today’s world, and which countries and companies own them? Also, could a working quantum computer be installed or created on the ISS because of the temperature of space?
Loved the video! and I want to go to the NASA one day
I didnt realize that coral was floresent! Thats really cool
I love watching science live, it teaches me so many new things. Thank you for doing this for us. I would love a radio class! I laugh so much on Area 51 segment.
I didn’t know that lasers could cool things down, that is so cool.
It’s hard to believe that Area 51 can actually communicate to mars. It really does show that our science and technology has really advanced over the years.
A little bit everyday goes a long way, thank you
I love the structure of Acellus, the way they break up the classes makes everything more manageable and organized. The Snoopy Award; so prestigious. Never knew the difference between FM and AM radio.
hello, I wanted to ask if you would do a digital art class? It would be really cool and it would help new digital artists. Digital art is hard and there is lots to learn so I would love a class like that
Congrats to the acellus student grad with such a great score
Thank you for doing this for us. I would love a radio class
how does a quantum computer work.
I never would have imagined a laser could ever cool something down, that’s incredible!
This science live is so funny and I laernd a lot from Dr roger billings
I would love to learn more about radio waves and stuff like that. Saying hi from KL, Malaysia.
I didn’t know that about space and their trip to the moon. How cool!
Radio waves are so cool!
I laughed when they said Area 51 and mars communicate.
The concept of a cooling laser interests me a lot!
I would love to have a Mega watch. That’s really cool it didn’t break with every test they did.
The story of finding a watch that would work in space was interesting.
I liked the segment; technology spotlight with Dr. John
Does NASA still give out the Snoopy Award?
A radio class would be SO fun!!
Does Acellus teach Morse code?
Does anyone know approximately when the Conspiracy Theories course is coming out? I just don’t know if it will take closer to one week or two years, prefferably the former
I enjoyed science live as always! Really cool to learn about radio waves
I liked learning about neuroplasticity of the brain and that studying in small amounts is better for the brain.
I love science live❤️
Our family had this video on last night and we enjoyed it!
I love the Area 51 part of the video!
This is awesome!! I loved this episode radio waves are so fascinating!!
Some people, think that the original moon landing is fake? What would you say to those people and how would you back up the claim with evidence?
That’s a pretty awesome watch
Technology spotlight is my favorite part of science live and I only thought that lasers burned and I didn’t know that they could also cool things down.
Really cool learning about radio waves!
I would love to have a pilot class and also could we have a space course I am very interested in mars rover. And also I loved the colors of the coral, and also I had no idea that height affects radio tower I guess it’s true you learn something new every day.
WOW! I learned so much about radio waves today.
My dad worked in radio for twenty years. A radio class would be very cool to learn more.
I didn’t realize lasers could be used to cool things off! What kinds of situations are involved in this process?
Do the extra activities change based on the grade level?
I watched this with my brother. We both think a pilot class would be cool.
A pilot class would be neat. Learning a new skill a never hurt.
I like the fluorescent corals. Learning about laser cooling was neat.
Lasers are actually super cool!!
Morse code is very interesting
I love science!
I love these weekly videos as science is my favorite!
i find radio waves super interesting! Loved this video
radio waves are interesting, I heard that they even detected radio signals from under Antarctic ice in the past…
I would like to learn to fly a helicopter and Morse code.
I’m learning a lot about distance and communication in science so this was fun to learn too!
I have always been very interested in radio waves, this live explained them very well.
Thank you for doing this for us.
How do scientists tell the difference between natural radio signals and ones made by humans
will there be a science live next week for the week of Thanksgiving?
I love to learn about the ham radio. And it was fun studying about radio waves too!
This one was my favorite so far!
The new shirts look amazing! Everyone did a wonderful job designing them.
I laughed so hard about the snoopy award
This video was very educational
I really enjoyed this episode. Thank you
This video is very fun and educational!
These just keep getting better! Laughing here in Texas!
This video really sparked my interest in radio waves! I’d love to see another episode on the matter.
I didn’t know that radio waves were so fascinating
Thank you so much for the video. I enjoy the information.
This was an amazing class
science is something that is so intresting, I love on how it tells you on how many steps you have left for your week goal and it’s intresting that lasers can also cool things down
I swear you make your jokes so funny!! and i learn so much from you without me getting bored. youve helped me learn so much thank you
R 51 is so funny
My dad has a HAM radio
If you point a laser to a piece of wood would it burn?
Thank you for this! A radio class would be absolutely amazing! <3
I never knew that much about radio waves, its nice to learn more about the topic. Is there a way to make a better frequency for distance and strength?
How long does it usually take for Acellus to design a new course?
I think radios waves are very interesting! There are so many things we can use them for.
I think the concept of putting computers in space, and using lasers to keep them at the correct temperature, is so cool. I love Acellus!
I really enjoyed learning about radio waves today
I never realized how cool radio waves are!
I REALLY WANT THE PILOT CLASS TO BE A THING! THAT WOULD BE AMAZING!
Acellus teaches you so much from just a one hour video.
How long do you study before you take a study break & how long should the study break be?
radio waves are so interesting.
I liked learning about Omega watches.
Who else has received the Snoopy Award from NASA?
I love radios waves! They can be used for sooo many things!
Why does height affect radio towers?
A pilot class would be great!
I laughed so hard about area 51!!!
science live is so funny and entertaining, i love listening!
I really love doing school with Acellus
I think Acellus is incredibly awesome
I liked what TOBIAS PRESLY taught today!
Lasers cooling something is really cool Nerver thought that was a thing, you learn something new ever day!
I’ve always been so interested in radio waves!
How are radio waves used in communication?
I watched this on my sister’s computer. Who else loves R51?
Thanks I never knew the cool history about how the Omega watch came to be.
It was enjoyable learning about the history of Morse code. When I was younger my dad taught my sister and I how to communicate “SOS” distress calls using a flashlight and with tapping. It’s an important skill to have!
Very interesting Science Live. I would love to see how Quantum Computers could be used in space
great story about omeaga watches!
A laser cooling something is extraordinary to me.
Another wonderful episode of Science Live.
I love watching these! I always learn something new, no matter how much I already think I know! Keep it up!
That science live was amazing thank you.
radio waves are astonishing! It’s just so amazing how they work!
Really enjoyed this one, Keep it up!
I love the bright colors of the coral, I would love to learn more about life in the ocean.
I look forward to taking the conspiracy class
Science is so fascinating to me
Do they still use watches for space missions to this day?
I love Area 51 so much!!!
How did Samuel Morse come up with the certain letters radio signals?
radio waves are super interesting!
It’s very interesting how the wrist watch was chosen and how it survived all of the extreme climates and tests that were made.
That was a very interesting story about the watch and the moon visit.
Radio waves is very interesting and fun to learn about!
Im so greatful for acellus!
This week’s “How to study with Acellus Gold” was very helpful. I struggle with ADHD, and I have tried studying with a consistent, and long routine before, however, I still manage to lose valuable time, and I miss important information. Therefore, I will be implementing all 3 of the “rules” that Dr. Joshua shared with us.
How are we supposed to track radio waves?
i do genuinely like when R51 comes on screen i genuinely love comedic relief characters they are so silly
If you were going to give radios another purpose besides communication, information, and music what would it be?
Very entertaining and educational video
How do you get a ham radio license?
The concept of the laser being able to cool something is crazy!
Acellus is super amazing i love the courses I’m taking and the things I’m learning! thank you!
i LOVE acellus I love how entertaining the classes and science lives are as well!!
A radio class would be awesome! I love Acellus
I didn’t know lasers could cool things down. I just thought they could heat things up.
Now I want to be a scientist. This is all so amazing.
So basically radios work by sending out radio waves
Morse code sounds extremely challenging yet fun at the same time!
I love Acellus!
I love learning in steps, it has really helped me stay consistent!
