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 🙂

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!
I love watching these science lives, they’re always very educational and give me so much information about so many different topics!
Loved this live and everything that i learned in it. Computers are amazing!!!
Amazing how easy the conversion is between hydrogen and electric cars, maybe once the weight problem is solved prior electric cars can be converted into hydrogen as a better alternative to lithium ion batteries.
It’s so crazy how powerful computers are getting! What would we do without them?
It is amazing what they are teaching robots…and what the robots are teaching themselves!
It really is crazy how far computers have come since the first ever computer I cannot believe it.
The rovers that made it to Mars, the Opp lasting 15 years, and Spirit lasting 6 years is amazing! Lots of data to transmit back and learn from
I love computers.
computers are insane
Computers are awesome! I’m planning to build one in the near future.
Technology is so interesting!
What would we do without computers
Wow rocket science is so cool the planning ahead probably takes a long time
The computer that changed the world is amazing 👏 🤩
I love the robot
The growth of computers from when they first were invented to now is a very wonderful thing to witness.
Computers are SWEET
I really love hearing and learning about Dr. B’s inventions and hearing his stories.
I love how fast computers have progressed through the short amount of time we have had them.
It is incredible to see how far computers have come since their inception.
I built a computer with my dad last year.
This was an amazing video.
r 51 was great.
Wow Mr. Billings is amazing!! I didn’t know he created a personal computer.
Loved the lesson today! Snakes are my favorite !
Technology has come so far.
It will be amazing to see how much technology will change our lives in the future.
How much longer do you think it will take robots to develop to be able complete more difficult tasks like Origami or putting a salad together?
Science live is awesome and computers make it the best.
I love watching your videos.
Cool video
I love R-51 he is so funny
Hi Dr. Billings, how did you come up with the idea to create the gold key that the government uses?
Technology keeps improving so much! It’s so amazing to know how far people have come in our inventions!
Computer are very interesting to learn about
That is truly amazing! How do you come up with these ideas?
Ai has come so far in such a short time. I can’t wait to see where it will go in the future.
Technology has came such a long way, It’s crazy to see the new inventions compared to the old.
Its amazing how computers and technology in general has evolved since it was created to what we have today!! And learning about the history of the computors and all of that is super cool! I wonder what technology will look like in another 100 years! I wonder if people 100 yeara ago would be surprised at how far its come.
Computers have gotten so smart over time and change the world! Especially even more now that technology is so advance. I really like learning about it. Thank you.
Love learning about computers ON a computer
I like the robot.
What a neat story! You are so inspiring!
It’s so cool how far technology has come in such a short time!
And the part where the robot did a slam dunk!
I liked the mars part
Loved learning about The Computer That Changed the World
I found the internals of the old computer very interesting and I will be doing more of my own research on the subject.
Computers are so interesting.
love the live, I love computers, so it was very interesting!
These lives have showed me just how far technology has come, and how fast it develops! Thank you for putting it into a better prospective and letting us appriciate it more <3.
Computers are truly amazing
What’s next after hydro powered cars, flying cars?
Thank you for an awesome episode and the opportunity to learn with Acellus!
I am so fascinated by technology
I love learning about computers this was awesome thank you
Wow thats so cool! Hydrogen powered cars? Do think think it will go further than just cars. Like other kinds of vehicles and engines, or maybe even airplanes?
The way technology evolves is a fascinating thing to witness, these episodes where you discuss your past experiences with innovation and technological advancements are very inspiring and bring great insight about our world.
It’s it crazy how much technology has evolved
I think that is is really cool the Dr Roger Billings invented the hydrogen car I would love too try to build one some day.
Technology has came a long ways. My mom uses computers and boards like this at her job
Watching from Connecticut
It is incredible how a small computer when they were first created they were big clunky and it’s just incredible how starting at that point we were able to evolve and make stuff that revolutionized the planet to entertainment Medical curity all of that is possible with computers you watch your favorite show on the computer guess what hospitals use to check your vitals computers and what do you think the government uses to protect us you know it computer
I actually love computers
so interesting how far technology has come in the span of 40 years. what can we use these machines for as far as advancements?
I always love to hear about other people’s stories and how they get passed either they learning disabilities or hard classes while balancing other things while doing challenging classes.
Technology is so interesting, I can’t wait to see how it will advance in the future. Especially with how much Dr. Billings has already contributed to and created! Great video
Its amazing how far computer technology has come.
love the live stream
It’s amazing how far computer technology has come.
I really enjoyed watching this science live video and learning about computers!!
Computers are so important. We can’t leave without them. So happy we have them.
I like this video. I am really interested in computers.
this is so cool
my previous home schooling wasn’t great at keeping my attention Acellus does a great job and these videos are actually interesting
Thank you for those who is part of the Science LIVE
and making it possible for us to watch.
I’ve enjoyed Science LIVE ever since!
What do the baby computer call his Dad
“DATA”
That’s so cool that you did so much with one computer especially since it was made in the 1970’s
How much does a average computer weigh.
I really liked the Robert doing origami
I enjoyed learning about the Billings computer!
Thank you for an awesome episode and the opportunity to learn with Acellus!
I thought it was a neat tidbit of info to learn how the twin Mars rovers were named.
I think that it is very cool that Dr.Roger Bilings invented the hydrogen car.
Thank you for another amazing science-live video Dr. Billings! I complete a lot of work trying to catch up to my friends LOL 😉
Go Spirit and Opportunity!
Dr. B has made my dreams able to be accomplished! He has offered me a scholarship in Acellus and a program that is accredited. I can complete high school faster with great grades, and be able to walk and earn my diploma! Acellus is truly incredible! DrB has/ will help me accomplish my life goals with a high school diploma.
Thank you for all you have done,
Nakova Crocker
I enjoy science too. I am learning about different rock formations. How long do you think it takes for rocks to form?
I love science 🔭🧪
Computers let me do school from home and im happy about that
The concept of hydrogen powered cars is super interesting! I wonder how long it will be before we will see a lot of them.
Almost everyone uses a computer, I don’t know what we would do if this weren’t made.
Listening while I ride my horses!
I think computers really made things a lot more convenient with sending e mails, learning things online, and entertainment itself. But what inspired people to make things like ChatGPT and Copilot?
My mom graduated high school in 1999! 😆
Funny ending, very educational video.
Technology is so interesting, this was very fun to watch!
It makes sense to give the students that really care about learning the scholarship because other students who don’t care as much wouldn’t use the scholarship the way it is necessary.
I’m interested in knowing which scientist forgot to convert the units from metric to imperial…
I really like this video. Do you think computers will evolve a lot more in the next 5 years?
Space interests me, and I was surprised that someone forgot to convert from the imperial system to the metric system.
The old computer costing nearly 4000$ is insane i could buy like three computers to day.
This was so ironic learning about a computer while on a computer lol!
The x-man joke in the beginning made me laugh so hard!
Computers are so interesting. What’s a feature you think all computers should have? Thank you for Science Live!
Its so crazy to me how advanced computers are and how they can do so many things.
It was so interesting to learn about Spirit and Opportunity!!
Real cool stuff! The Billings Computer is so cool, all the parts are really interesting!
AI is soooo cool, i cant believe that it was able to pick up a CLEAR container. The camera makes it harder to see clear. however made must be super smart.
It’s interesting that one little microchip can do everything on a computer.
Thank you for sharing your journey in developing your own computer. I love how you never gave up and kept going even with you hit different obstacles.
I like how he show the microprocessor and how it looks.
I remember in Disney in Epcot the ride spaceship earth shows the invention and early years of the computer
wow! that was cool. Thank goodness for technology
Dr Roger has an insanely diverse mind
That is amazing !
I love watching science live. It teaches so many cool things! I love learning about things that are happening now.
I love watching science live. I learn so much about things I wonder about!
I loved listening to the story about thr rovers on Mars! So much planning has to be done.
That’s cool ! My great grandfather helped build the ENIAC!
It is so cool how much they have changed!
I didn’t know that the first rover was on mars before 1999.
You should talk more about this computer. Maybe tell more story of it.
Computers are so amazing. I still think its crazy that so many things we use everyday use computers and that they were not invented that long ago.
The astronauts should of been rescued sooner.
Thank you for the history lesson on computers.
What exactly inspired this new idea of technology, such as AI, Chat GPT and Gemini? I really enjoyed watching this!
I love this live!
Why weren’t the astronauts rescued sooner?
I can’t imagine life without our technology!
It’s really interesting how you found out to put the transponder in the power supply to fix the issue with the monitor.
It’s crazy how computers changed the world epically this one!
It is really cool they figured out to use joints instead of springs.
I am so happy that we have technology:)!
Brodee was excited to learn about the Mars rovers. She wants to go there.
technology is so interesting and so fun to learn about!
so glad the astonauts were rescued by Elons space craft.
I likes the story about the rovers to space.
That was fun; learning about computers
Love watching these
Woah, people have powerful and creative minds for these stuff to be invented!
Dr.B made the video understandable an clear to all students the way he advance his knowledge.
WOW!
This episode was really cool! I love photography and I loved how the photos taken in space and how the machines to take photos are developed. I also thought it was cool that Dr. B talked about the 2 astronauts being rescued recently on the video. I like that Acellus talks about current things too.
Mr.billings you inspire me do help other people get as smart as you.
I love mars
Mr.Billings you should put a acellus mug in the item shop
Computers are the way of the world now.
Wow this is such a cool invention, technology is so fascinating!
How long ago was the first computer created?
once computers were mainstream how much did they cost?
Computer That Changed the World, I cant say I would want to get stuck in outer pace for nine months!!!
Dear Mr Billings, I appreciate your efforts to create better computers it has helped it had incredible effects on the world I’m sorry you had to go through betrayal and that people doubted you in the past well done and i hope to see more of your science live videos.
The Billings Computer its so cool and I am so thrilled every time I hear about it because it truly did change the world.
It’s so crazy how computers can do this!
As a teenager who grew up with technology, I cannot imagine the world without it and how things got done. I am so thankful for this invention, and the continued progress.
I am also glad that the two astronauts are finally back home.
These Gemini Robots are making huge progress in so little time. Its amazing !
Prediction: in 6 months robotics will have become so advanced that they will do the dishes better than me!
In 3 years, they will be able to do backflips and drive cars.
In 10 years, they will become the strongest, fastest, smartest things on the planet.
In 15 years robots will fight for their rights!
I think mars will be the next habitable zone after earth!
Computers changed everyone’s lives for the good or the bad doesn’t matter, I wouldn’t be able to do Acellus without it!
Thank you for the Science live, or should I say Science replay!
Haha, I just love how working hard can motivate others to do the same. Friendly competition is always fun!
I’m so glad this was invented! I love technology!
I liked to learn about the AI robots and how the mars rovers actually got to Mars!
Im wondering how Dr. Roger had the guts to trust again when rehiring for the computer invention.
Great live
It’s crazy on how this computer changed the world!
Dr. Roger’s is a very smart person, it’s very interesting how he’s made multiple breakthroughs.
the joy in the control room with the successful landing of the Mars rovers was so cool to see,
How long ago was the first computer created?
Without computers, would it affect the invention of the phones?
Love the video! It was a great watch and I learned a lot from it!
Area 51 is such a funny character. I am so glad computers were created!
wow! this is so cool!
Who had the first ever idea of a computer?
Will another computer be released with more power & features?
Love watching!
That was really cool
I loved this video!
I love this.
how long did it take for you to make the computer
I love science. New inventions are the future.
