Great!! I love computers.
so awesome!
This was very interesting in regards to the beginning of personal computers.
What an amazing accomplishment!
I love this school so much 😍
This video was really inspiring
Dr. Billings and Pajet Monet are so inspiring and seem like such kind people.
Since I’ve been alive, the all-in-one computer has always been an option. I can’t imagine life without it. Thanks for the video..
Dr. Roger, we loved the way you share your creations and the challenges you have faced.
The Area 51 part was hilarious! Your little act about AI “thinking for us” was so funny, but it also reminded us of something important: AI is here to streamline and accelerate processes, not to replace our own pursuit of knowledge.
Hugs from your new fans in Brazil.

I learned a lot of new information.
so fascinating.
Thank you SO much for calling me out in this video it made me scream with joy when I heard me name called out I truly enjoy watching science live and I hope to hear more shoutout for more students in newer epeisodes
That’s really cool
The robots were controlled by codes or words love it 💖💖
I really enjoyed learning about mars!
This computer really did change the world
Woah that’s amazing!
This is so cool! Computer engineering is so fascinating!
Early computers were so big!
Wow, amazing!
Computers have come a long way. I learned about computers in elementary private school.
It’s so cool to learn about computers
that’s so cool my uncle built his own computer
It is so interesting about the history of computers. Dr. B is fun to learn from.
Interesting how computers have come so far from where they started.

What do you think would be possible if computers used a number system besides binary?
When was the first computer ever built?
Who knew???
This episode was awesome! Computers are so interesting
Wow
pretty cool
wow!
wowzers, computers are so amazing. <3
I think the robots Dr. John showed us we’re super cool. The way the robots were able to do intricate tasks was awesome. Seeing the rovers on mars really piqued my interest. The computer Dr. B invented changed the world and the way we view technology today. I am truly inspired by the story he told about his life.
Awesome.
Cool video!
The robot is pretty good at origami
wow!! amazing video!!
Computers are so cool!
That’s so cool!
Computers are so interesting 🙂
Man im a coder my self and this was very interesting!

I didn’t realize before how much computers have evolved!
Thank you!
Great video!
So very interesting
It is so awesome to see how much Dr. Billings has done and has been involved in, and to be learning from someone that is so accomplished is really exciting.
That’s cool!
I want a robot!
Great video. I love space!
cool!
wow!!!
wow!!
Glad those astronauts are back home safe
this was very interesting
computers are so cool! and its so interesting how they were created!
Love you science, but not as much as I love science live
I learned that there is all kinds of robots used by AI and they are smart.
This was a really neat episode! and I love seeing R51!
Man, what would I even do with out computers?
I had no idea they could do that.
The first Rover that was invented looked cool.
It’s really crazy how it took only one computer to revolutionize technology as we know it today really cool video.
I love seeing things about robotics in these videos!
R51 is so funny
I think that these videos should be longer because they are really fun!
This is so fun!!! Computer really helps us in this time of the world.
funnn!!!
This video was enlightening
While computers have helped us advance far more than we were able to before, it is sad how most children do not go outside anymore. Nature is beautiful and wonderful too 😀
This video fascinated me and I know computers in the future will make such an impact as this one
Computers are amazing. I wouldnt want to live in past without them.
I loved this episode
It’s interesting to see how far computers have gotten!
R51 is so silly!
favorite computer-science exploration?
I’ve always found computers so cool
R51 is one of favorites on the episodes !!!
I love R51 energy
My Mom had this computer. She went to college and studied Mirco computer Specialist. If you are wondering how that can be, my Grand Aunt adopted me. Thanks for this history.
Great video really loved it.
NASA sent maltiple Rover’s in a tiny pod thats good enough for rover’s to fit in, and it Use’s balloon’s/ball thingy’s while landing so it doesent crash and explode And has a parachute and the rover has solar panel’s and flexible leg’s and other stuff. Hydrogin is Very light.
I had no clue computers can do all that.
How many inventions did Dr.B make???
Computer science is so fascinating!
I love R-51’s energy!
R-51 is smart like Dr. B, great ideas.
My Gramma says she thought that Word Perfect was a lot better than Word back then.
Computers have changed so much over the years.
What prompted mars further discovery?
I am so thankful for Acellus and Dr.B after my family has tried so many other curriculumns we’ve found that Acellus is the best! We have referred so many other families to Acellus and it is the #1 school to go to. My family and I are so very thankful for what you have created Dr.B!
Love it!
I love the robots.
Absolutely amazing!
Technology is so cool!
The creation of computer really impacted how our lives are today!
bro created the “inter-net” and he has no credit?!
I would love to learn how to build my own computer.
I love learning about computers and how they evolve.
I loved the robot
I love technology
I bet that I’m inspiring some people too because I had some classmates that were almost half way through every course, but there just now starting 6th and I’m past my first and second exam on all my 7th grade courses, and I’m in Stem2 and Learning Excel! and I make so much gold in one day. I really hope that I’m inspiring someone.
It was interesting to learn about how Dr. Billings had ideas about how to create computers. Also, that he had conversations with Bill Gates about it.
Computers are so essential to our lives!
