I watch this with my family!!!
Learning about how WIFI works is awesome thank you
Hello from Virginia.
I didn’t know radios worked like that, Cool!
i wonder if radio waves could be amplified and weaponized into a space laser
The smart string was amazing
Currently I am thinking about working in the medical field, perhaps with newborn babies or perhaps working with other children that have special needs. I was very interested in the Technology Spotlight where we heard about the possible development of smart clothing. I might not want a computer on my sweater or gloves, but I can see where scientific research may use these wires for possible brain implants that might control epilepsy or give a child that is mute the ability to speak. With science the sky is the limit and if you can imagine it, that discovery may be possible. I learned to never give up and keep on trying. Who know what you might discover!
wow i learned a lot from this live
Wow I have never heard about blue monster Galaxy!
Favorite part of my week!!!!!
How did radios cost back then? It is awesome to see how much technology has advanced.
I think it’s interesting to learn about WI-FI and how it started
The way they are able to show how far we can go with present tech amazes me!!!
Another very interesting session of Science Live. So many exciting this brought to light. I was interested when I watched Break Through Moments in Science. I never really gave much thought to the idea that something that was invented 20 or more years ago, could eventually be put to use in a current invention.
I always learn something new and am always excited for the next Science Live.
That’s really cool that back then they had radio’s like that
Learning about how WiFi came about is pretty cool . I enjoyed it very much!
very nice video! funny and with cool information
This was so cool to watch! Loved learning about the computer string!
I love science live
I love science live its so cool!
This live was so cool to watch can’t wait to see what yall do next!!
Building your own radio sounds pretty fun to do
This episode was very motivating and inspirational. I really liked the reminder to think independently and focus on the basics.
Amazing and engaging live, very cool to see the future of technology
Science Live is so cool!
How do the people in chin put technology in the thread?
Lol!! Love A-51 😂😂
I really enjoyed this weeks video!
This is by far my favorite science live!!!!keep up the good work Dr.Roger Billings.
I think it’s awesome that you can build a radio out of stuff from home
I’m glad to have Wi-Fi
I personally think all of this is interesting!
I always thought about how computers were made.
these people are so awesome! thank you!
science live is interesting
I could never live without radios or WiFi!
As always, Tobias had the most interesting segment and I loved learning about WiFi!
why was there pirates 😂😂😂
This was so interesting to watch! I always wondered how Wi-Fi and Radios worked and this video answered all my questions! Thanks!
Who created the first radio station? I enjoyed learning about WIFI
i love r51’s butterflies
The string computer was interesting.
I found the computer string very interesting. It’s cool how it’s like a Morse code that travels back and forth billions of times per second.
This really brought some light to me on how WiFi and radios work, thank you for today’s episode!
Wish my mom’s truck antenna wasn’t broke! Makes for really long car rides! Thankful for further advances in technology that I can use to rock out 🙂
Tuned radio sounds interesting.
I’ve always been interested in technology and how wifi and radios work and their history, good to know.
I love learning about morse code and radios on science live, I’m always learning something new about them.
Thank you for the information 😃💥🧡
I watched this week’s video. I learned a few new things about old laptops and found it interesting
That was interesting about the WIFI
I like the pirates of radioland!
That’s super cool how wifi and radio work!
loved this episode, looking forward to the next!
I really like how you can put transistors on string.
I like these lives because they talk a lot about science and stuff that I didn’t know and how they work me personally I’m a big science guy that’s what makes these lives so interesting and cool
It is really cool that Wi-Fi worked because a guy did research about black holes. Acellus is outstanding!!!!!!!
THIS ONE WAS SO GOOD!
The future aspect is super cool
Can’t wait to make my own radio.
That would be really cool for the string to have LED through fabrics in clothes.
I like the computer thread. It would be cool if I had clothes that I could send messages to people on!
is this computer thread for sale to the public
This was very cool!
Great and interesting live as always!!
Hi! Just watching another lovely science live. Thanks
I love Science live😀😀😜😜😜😜❤️❤️❤️❤️💕💕💕💕💕💕
This show is cool!
What is the purpose of school if they are just going to give the students apps for learning?
wow i have always wondered how radios work!!
hello from louisiana!!
I like the R51 radio idea
This is so cool! WiFi and radios have always confused me on how they work and how they were named, so this really answered most of my questions.
My Grandma used to work for a semi conductor company and she told me how these chips work but there is so much more to learn with how wi fi and radios work. My mom also knew Lou Doren who made something for radios
R51 is so cool and funny !!!!!!!!
Amazing live! Radio frequencies are so fascinating to me!
The Australian accent was pretty funny!!! I also enjoy how David and Celeb explain things!
very interesting loved this episode
This was a really cool science live!
I liked the part when they talked about the radio.
Enjoyed learning about radios and r51 was funny
the computer string was pretty cool showing how the future can look like with tech.
Morse code is very intriguing.
Hello from georgia
I really enjoyed this week. It answered quite a few of my questions.
Nice! Thanks for the video
This is so awesome!!
That was really interesting. The invintion of the radio is important!
Marconi was a strong and determined man. He wouldn’t stop until the job was finished.
This is so cool! WiFi and radios have always confused me on how they work and how they were named, so this really answered most of my questions.
I love learning about wifi
The most interesting to me was talking about radio frequencies very cool
Great and interesting live as always!!
hello from NC!
How fast is Wi-Fi used in. 2026 DR.B
Radio’s are so cool!
how many people used radio back then?
That’s actually interesting how you can do that into a thread kinda impressive
Radio really is interesting
Probably everyone who had one.
This is so cool
It’s amazing how you can build transistors into little threads.
I loved radios because they were so universal, you could listen to news channels, songs, people talking about diffrent things, ect, so its facinating to see how its evolved
I want to build a R51! That looks awesome
Hello from North Carolina!
Hi, from Conroe, Texas!
I always though WI-FI stood for something, crazy to think its a made up name.
I was very impressed with the school’s success, congratulations.
I liked how the video explained the topic in a clear way.
This was so cool as usual!
I loved listening and watching this weeks episode! Listening to what The Proteges teach and explain is so inspiring and I love learning everything they have to teach! Also, R51 is so hilarious and always seems to make me laugh; glad to be joining in each week, it’s such a pleasure.
This is stuff i have never seen before, thanks Dr. Billings.
Hii, I Loved it!
A lot of the time we tend to overlook an abbreviation , this is a perfect example , I never understood why WiFi was called WiFi, now I know!
I like this podcast
That Australia Accent Was Really Funny!!!!
Wow! The computer chip in the thread is so cool!
I loved when they started singing. LOL!!!!!!!
And how Caleb was so serious when he said “And three weeks later it was broken.” LOL!!! They are so funny!!!!!!
🙂
That’s a very high difference in percentage of students passing. Amazing progress to see within the year! Shows that there is a lot of care and consideration for each student to be successful!
Hello from Philly. Very educational and fun!
Hello from Florida!
HELLO I’M FROM BUFFALO NY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
How they came up with the name for Wi-Fi I think it’s pretty amazing. I think it’s so cool how much we rely on it today
I love radio its so cool.
THIS ONE WAS SO GOOD!
Radio is really interesting. It’s crazy.
Learning about the radio ir so interesting and fun!
have a good monday
How did they get the computer chip in a string
Hello from Arkansas! Great live as always.
how can chips in your phone receive
how do you make a Radio?
How much of that wire would you need to make even small things? It just seems like the sort of thing that might be ineffective.
How cold can the string computer chip withstand?
How wi-fi and radio frequencies work is so interesting to learn about
I love them pretending to be pirate :
wow thats crazy that wifi is a name.
Could you explain how a jet engine works next live?
How does ethernet actually act as an internet connection?
I so excited for that airplane class.
The radio was fun to learn about!
The coolest thing I’ve seen on Science Live is the computer chip that Dr. John talked about. It looks like a string and it can withstand boiling and freezing temperatures. It looks like a fishing line that you can turn on an off with your fingers. It was interesting to hear from Tobias about how WiFi was invented. We use WiFi everyday. Tobias said John Sullivan, an Australian scientist had helped invent it. Caleb and David were dressed as pirates and said how radios were tuned to send out radio waves long distances. They said that in 1857 the first wire was laid across the Atlantic Ocean. 3 weeks later it was broken.
I love science so much! Its so fun and cool!
The name WI-FI is cool! Science Live is awesome!
I would like to get the Wi Fi radio kit and am excited about how to fly helicopters.
this science live video is very cool and I love how WI FI Was a made up name.
I love watching science live every week thank you all for being here
the strings with computer componets are pretty sick I would love to have some maybe i can find a way to use them to help catch a fish that keeps snaping my line.
Yall are so funny I just love watching these videos
Wait, they made up the name of WI-FI i thought that was official.
Love this science live! Hope everyone is safe and well!!
smart clothing from a computer chip wire would be cool but also kind of weird
I’m definitely going to research dark stars and blue monster galaxies now.
Science lives are so entertaining and fun.
wi-Fi being made up is cool but why did they name it Wi-Fi?
Hello from Chicago!
Hello from Kentucky. Home of colonel sanders
What is a blue monster? aka the black star?
Computer threads are inspired by sushi rolls.
It’s super interesting how something that appears to be a thread can actually be a computer chip! I also found it fascinating that the chip’s design was inspired by sushi!
Are there any possible applications of the computer thread in the aerospace field? Like, reducing the weight and space needed to accommodate sensors and electronic equipment in space suits, or a space shuttle itself? What is the coldest temperature it can tolerate? Can it withstand moderate amounts of radiation?
smart clothes is intersesting and cool
The stat of WiFi was interesting to learn.
I love your science live videos they are always awesome!😄
Hello from Texas!
I like how the radio doesn’t connect to other random frequencys.
This video is very interesting wow
I like learning new things every week, and the computer thread is very interesting.
R51 is funny!
I love the idea of the string computer that’s amazing!
WI-FI being a made up name is pretty cool! Crazy how much we use it today.
Hello from Oregon!
I was actively wondering what Wi-Fi stood for as the topic was being brought up. Thank you for answering my question! Even if it was just “why fi?”
the way David just gave him the tissue box! haha! the invetaneres are funny 😛
the ventioneers return!
Interesting about WiFi!
Your videos are great.
I loved this episode of science live!, good start to the week.
I love Dr Billings!
I have always wondered how messages are sent overseas!
I would like to be able to earn the R51 radio with gold credits. That would be neat.
Learning about the radio was my favorite part.
I would love to have a radio in the shop.
People can make radios that actually talk.
I really enjoyed this live this week. Very interesting .
Mr. Hertz taught about circuits.
I really liked the computers part.
Science live is always a fun watch for me and my family.
r 51 is the best
SO cool!
How interesting and forward thinking… a wire as a computer chip! Where will this go…
Its amazing that computers and processors can be created to be as small and flexible to look like the thread in the video. Technology has come so far.b
I like Dr Tobias because he is funny
R51 was so funny
It’s interesting learning about how the WiFi began.
What year was radio invented and become popular
I am so happy he did Wi-Fi! I hope it never breaks *
