How long did it take for the six people to make the big circuit work?
Hi from Texas.
Bullet trains are so cool. *
I wish these could last longer because of how cool they are!
When was the first circuit invented?
really interesting about the circuit
Love watching Science live!
integrated Circuit Introduction
Hello from missouri
I learned about circuits on Acellus!
How did they make the train go so fast?
I loved this live!
Very interesting to learn about!
Science Live is so cool
i love watching these they are so fun and i love them. How long does it take to make the script for these?
I hope everyone enjoys this as much as I do
The comet should be named Sky-Shatterer. How long did it take to make that tiny transistor by hand?
Always learning something new with these videos!
hi from AL
it was really cool learning about the circuit !
Hello from Arlington TN.
What will the next episode of sciencelive will be?
Mr Billings lives are always so interesting!!!
I liked when you talked about the bullet trains
I would love to hear more about how our wireless internet works.
Happy birthday Thomas Edison.
R51 is so funny
learning with acellus is so cool!!
I loved how they explained the inter grated circuit and how important they are to making smaller computers and how much faster and better they have became over the years
What happens when the comment gets to close to the sun?
Hello from NY
Super interesting learning about computers!
Loved the live this week!!
This was a great episode!
I love R51! Absolutely hilarious
You are so cool and I love your videos
It is very interesting to see the evoloution of circuits. 17,000 vacuum tubes is a lot to keep up with.
R51 is awesome and this program is great
Science live is amazing!
i like bullet trains they look like a plane!
Loved learning about the comet that bursted into a bunch of comets!
The bullet train safety measures are so incredible. The point and call system is so simple but incredibly effective it was even adopted by New York subway conductors.
So happy to see Dr. Billings! He’s always so fun to watch!
i love the science lives ! i never knew today was national inventors day.
Haha that’s my favorite joke yet! And yay happy national inventors day!
Wow bullet trains are crazy fast, thank you for telling me.
I love this it’s so funny and a good tutor for me to learn the stuff I need.
We can’t wait to see our first comet of 2026.
How small can an integrated circuit get before it stops working?
I really want to go on a Japanese bullet train in person.
Integrated circuts are cool, actually, I’ve made a pcb integrated circuit and shipped it to my house!
Nice hearing about the circuit and the bullet trains!
Comment ” This was a was a very educating video.
I really hope the comet isn’t too close to the sun because that would be awesome to see! Also the bullet trains speed running on cables was cool.
Having these lives with Dr. Billings is the best part of Acellus!
I liked the bullet train part!
Hi from Vietnam
Happy chinese New Year!!!!
I enjoyed this episode a lot thank your!
Could you do some science on the human body and immune system?
I’m super excited about the science fair and all the cool things people make!
what is the meaningful reason that we have integrated circuit introduction for?
Comets are cool.

Thank you for helping me learn something new. I am so exited for next week!
Hello from S.C
The structure of a space comet looks interesting to look at. Especially the dust trails and light and it has different types of color. But I’m curious, what materials make up the comets and their structure?
I loved the explaining in this video, it helped me understand better.
Hi from PA
Hey from florida!!

I always thought bullet trains were cool with how fast they can travel
Greetings from New Mexico.
Wow!! The Protégés keep getting better and better!!
I really like science and learning about circuits.
these are my favorite
It was interesting to read about the integrated circuit.
I love bullet trains
integrated circuits are tiny chips that contain many electronic components on one small piece of material. They are used in devices like phones and computers. They are used in devices like phones and computers. They make electronics smaller and faster.
I always thought that bullet trains were super cool with how fast they can travel.
I am fascinated with trains. My mom has taken me on different train routes on different kinds of trains.

I like comet 51
Intergrated circuits are a helpful technology invented by humans.
thank you for teaching us about this interesting circuit
Great lesson R51!
Here from Indiana!
Today’s lesson about the integrated circuits was really interesting today I learned a lot.
Loved the bullet trains!
The topics covered on these lives are so cool!
I am going to look out for the great comet of 2026.
I would love to go on a bullet train one day! A good comet name –
North Star Comet.
I like R51. He’s so fun and I’m enjoying learning about computers.
In 1964 in Japan they first deviewed a fast moving train called the Bullet Train. They thought it would be a good idea to do it then because it was around the Olympics and the whole world would be watching. They would run it from Japan to Taiwan. The Bullet Train went really really fast, travelling about 130 miles per hour and it went 190 feet in 1 second. They are trying to make it without wheels and to run on magnets in the air above the tracks.
These science lives are so helpfull! 🙂
This is AWESOME
I am excited to see the comet in April.
Roger Billings is so great!
Integrated circuits have changed so much.
Thank you for this week! Can’t wait to log in next week!
I love comets! I think we should name the new comet Little Mac because that is my nickname my aunt gave me. I also like the fact they are gonna use magnets to run the trains.
I think it was interesting to hear about the integrated circuit.
I loved the bloopers!
I love science live.
The Japanese word for train — specifically an electric train — is 電車 (densha) which literally means electric vehicle
wow those trains are so fast!
