poor r-51, he always has such bad luck 😉
I love the new 3D printing idea!
Thank you for this Science Live!!
I thought it was cool how Dr. Roger Billings knew Frederico Faggin and how Roger Billings made the computer better by making it so everyone could have their on personal computer.
I’m always learning from science
Rebecca is my favorite teacher in both math and ELA
Hello from Florida! 🙂
So if Dr.billings made the first computer, who is making the ones right now?
The videos are super cool!! I liked how it spammed the tacos on the computer !! haha
Very cool! Can’t wait for the next one.

Commenting *I love the work billings has done with computers it’s really changed are lives for the betterw
I love Acellus
This video is so awesome keep up the awesome work, May God bless you
Thank you for the great information!
This was so cool and amazing!!
Happy Tri-fact-versary !!!! Wow 300 episodes of Science Live.
If we get a science credit for 100, do we get a science credit for each 100 episodes or just one?
Im thankful we basically have hand held computers (phones)
Have a great week and God Bless!
300th episode!! Congrats and wishing everyone all the best, thank you for teaching us so much.
This was so fun to watch
Awesome!
The AI part was interesting. Technology has grown so much.
I really like todays 300 Episode of Science Live. It was interesting to learn about microprocessor and the history on computers. The timeframe from 1970 Mainframe to 1977 BC-12. Super cool.
hi from NY.
We all know that printing copies or work is slow so some scientists study that some ways of making printing more convinient is by reducing the time or speeding up the work. Some printing machines can use 0.6 SEC speed as an option, so with this we can make printing more efficicent and can print smart phones, types of smart robots, and even devices.
Dr. Billings is now the computer godfather in my mind now. I can’t believe I never knew he made something so important! Easily my favorite science live.
Those computers were huge. I’m thankful technology has progressed so much.
Wow, 300 Science Live episodes!
Loved today live I’m so happy to watch micro controllers
What kind of tea is hard to swallow? Reality
I love this video!!!
My favorite part was the protejes, as always.
Cool episode!! Loved the Ai part it was so interesting!!!
I love Acellus!
Very nice video, I learned a lot
That is amazing what Dr. Billing had made. love it !…
These actually make me think on a deeper level
I think it’s incredible that you were able to create one of the earliest and most successful PCs.

Hello from Georgia.
Favorite episode ! AI seems so interesting to me!
there try to make 3d printers faster
My birthday is soon. I’m using math to count my days.
ama-zing!
Where can you micro controllers.
I had a great time! cant wait for the next live!
cool micro contollers
I learned a lot of interesting things this episode!
It is crazy how we are holding or using a micro processor to learn on Acellus and do many other things.
I really liked this week’s science live!
I am a big fan of Roger Billings!
The inside of a computer is amazing!
I loved John’s section was really fascinating
Do you think that you can launch a class on space?
I can’t wait for next weeks science live.
I love science live!! Thank you 😊
A very motivating video.
I’m actually really worried about AI. I think that it will ruin everything we have done.
I never knew that about 3D printers. It would be interesting to see how this technology further advances the future.
My mother has AI for her job . I told her to make sure it wasn’t hallucinating !
Those transistors are so small and cat so much. It’s awesome.
Awesome video!
My grandfather was watching with me and said he had a computer so big it took up the entire table. He said he recalls saying, one day they will be giving away calculators.
The super fast 3D printing is really cool!
