I love science live 😍
Wow thank you Roger billings for teaching us about computers!
Science is amazing.
Before these lives I didn’t know you could make science entertaining
How big is the 3D printer?
That’s very interesting how all that electronic things were made and invented.
i love computers so this was really interesting!!
Now I’m hungry for tacos!
I enjoyed this lesson. A LOT
Thats gotta be the most interesting video of computers
I really enjoyed this!
I glad they make things step by step .it’s helps alot
They are inventing a new way to 3D print with lasers.
10 x as faster
They use a little metal plate to make it not as hot so the machine will work better
learning about how technology is was interesting.
I love the jellyfish galaxy!!
3-D printing is so cool!
I loved learning about 3d computers. It was so interesting!
I LOVE THE COMPUTER PART
This was so fun to watch!
i LOVE LOVE LOVE SCIENCE.
Science is one of a kind.
R-51 is so funny
That is the coolest thing I’ve ever seen.
I now look at computers differently!
great episode so interesting about the computer
This science live was amazing!
i loved learning about the 3d printing
jellyfish galaxy was sick!
Wow, printing that fast and that accurate is just insane
Computers are so cool! I like learning about the history !
The Proteges session was really cool in this episode!
Caleb: You thinking what I’m thinking?
David: Tear it open and see what’s inside?
Caleb: Exactly.
(Explanation…)
David: You thinking what I’m thinking?
Caleb: Tear it down and build it again?…
David: No! Tacos!!!
They are just hilarious!
Watching from Tennessee!
I enjoyed watching today’s science live!
Dr. B’s greatest invention: Caleb
300th science live! happy anniversary!
Wonder how this computer technology will work!
If i had a 3d printer I would make collectible items to put in my room.
Hi from SD!
I loved this one so much
I thought the 3D printer was so cool!!
Thinking of a project
Learning about the history of computers was really interesting. It’s amazing how technology has improved from the first microprocessors to the powerful computers we use today!
Science live is so interesting Roger billings is so cool I would love to meet him
3D printers are really cool
I really loved the video can’t wait for the next one.
I loved to learn about the computers and how they work and how they evolved.
Hello from Tennessee!
its always something interesting! i love it
I want my own 3d printer
It was extremely interesting to learn about computers!
I love science live
Its amazing how far computers have come in such a short time.
Is there a microprocessor in my car?
I LOVE SCIENCE LIVE DAYS!
pretty interesting video
Loved this science live!
The Billing’s computer looked so cool
3D printing is cool.
i love this so much
The Z80 was very popular.
Science is the best subject.
Wow that is really cool about computers!
I found the jellyfish galaxy really interesting, and learned something new!
That a really old computer
I love science live
I loved the video, very interesting!
It was so fun learning about the billings computer!
For my birthday I’m gonna ask my mom for a 3d printer.
This live helped me learn so much.
I love science live
it’s crazy how computer were made . Sharks and computer having Megan bites is so funny
Man, I never knew that Dr B made the first all in one computer! I only knew him from science live!
I have always been fascinated with 3D printing. I figured that things would have progressed faster since the idea came to conception.
It’s so interesting to see how microprocessors have changed so much over the years!
This was a great science live!
Hello from VA!! <3
As always very interesting
Thank you for these awesome videos!
technology is blowing my mind
The way they’re advancing 3D printing is so cool!
My mom has a 3 d printer
That squid was amazing. I had to rewind because I missed it.
This is genuinely one of my fav eps! <3
thank you for teaching me about all of the fun science experience.
I love science Live and acellus ❤️ it’s so fun to learn new things
I loved the jellyfish galaxy!!
I really liked learning about the billings computer but I still would like to have more fishing episodes
I enjoy doing science live with my parents and sister.
I always wanted to know how coumputers work.
Computers are so interesting and cool!!
love science so much it is so intrestingto learn about
hello from Texas!
Great science live!
I personally think that the future is gonna be awesome and its gonna be because of roger billings
Favorite day of the week, always look forward to science lives
Thank you for this one! 3d printers are awesome
Happy 300th episode!!
great video I love it.
The history of computers is so interesting. Its amazing how we’ve advanced over the years!
Thank you for all this amazing information.
I really enjoyed learning the electronic components and how far technology has become.
Yes technology has really evolved over the years
I LOVE SCIENCE LIVE
I really enjoyed this video!
computers in history is very interesting.
I find it interesting that some researchers at The University of Waterloo have identified the farthest jellyfish galaxy, which is a galaxy that has long tentacles coming from it when zoomed in from far away.
AI really is one of the biggest breakthroughs in modern day. Just a couple years ago we were astonished with it. Now it’s the norm. Crazy how far tech has come.
Technology spotlight never fails to impress me!
Science live is so great
I LOVE SCIENCE LIVE
I love technology good video
Watching from GA
This is so interesting!
3d printing so interestingly
I really liked the computers part
The history of computers is so cool.
I love learning about computers, they interest me alot.
The 3D printer is cool.
I enjoyed hearing about the history of computers and the computer that Mr. Billings invented fifty years ago!
Yes is a really smart and computers are really hard to make and complet
How are those little engraving put on the chips at the time?
Love this class!
we love science live days!
Thank you for this video!!
science is really amazing.
Yes science is one of my favorite class
This was one of my favorite science lives yet. I loved episode 300

I have never used a 3d printer but I have always wanted try one.
It’s very crazy to look at computers from the past and see how much they’ve advanced.
Seeing a 3D printer is so cool and I love making little things with mine!
The history of computers is always such an intriguing subject, always a joy to learn about.
I wish I had a 3D printer
Its really cool having the creator of my school also the creator of the first computer.
The 3d printer is cool.
hiiii from georgia
I loved the part where they talked about the history about 3D computers. That’s really cool!
My grandmother is in her seventies and likes to tell me how things were back in the day. It’s just crazy how things have change!!
Great live! Episode 300!!
I think it is amazing how creative and innovative humans are, especially how computers were even invented

Happy 300 thank you for teaching us every week!
Wow. This is so interesting!
I loved the video it was so cool!
I love science live and it is so awespme that this lesson was about computers because I love computers.
Ms Rebecca is on of my favorite teachers!
It was very interesting I can’t wait to see about 3d printing.
i loved when they talked about space its my favorite.
How do they get the rosin into the shape of a squid in the first place?
I think it is cool how much we have advanced within a 50 year period. My mother old me about when she was a child and she told me about the fact that tv’s were uncommon and just big boxes with screens, and phones were attached to the wall, now we have smart phones, computers, and 50 in. tv’s. Crazy!!!
Computers are so cool!
I really enjoyed this episode. It was so interesting learning about computers.
Dr. Billings is super cool. The Billings Computer was the biggest computer I have ever seen. Thank you for a really fun episode.
Tacos
It’s almost unfathomable how much smaller processors have gotten since the late 70’s. Only 30 to 40 years later would we begin creating them at the atomic levels!
I’ve been watching almost 2 years!
Technology advances have grown so much we can 3D print almost anything we could think of which I find very intriguing to learn about.
I love when they showed the 3D printer.That was so cool!!!
Man, the history of computers has come a long way.
really helpful I thank Acellus for helping me
Computers are actually so cool
So Awesome that its the 300th episode!! you guys are so cool!!!
