This is so interesting!! Thank you Roger Billings!!!
I didn’t know the Navy invested so much into STEM
Congrats to the science fair winners!
Wow I never knew how much went into computer making!
LOL! When Tobias was talking and mentioned that your head bobs when you walk yet your vision stays the same. I had bobbed my head up and down to see.
A cpu is the heart of a computer
What Makes Computer Work uncovers the intricate interplay of hardware, software, and logic that powers every task from simple calculations to complex operations.
You make this fun, entertaining, and inspiring.
Jesse what a smart kid!
I wish I had you as a teacher!!!!

I love to golf, and learning about the golf ball was fun!!
I love using AI, it is so helpful on most projects I work on.
i never really understood what the gyro was until now
I loved this video!!
I am very thankful for computers.
It was cool to see who won!
How incredible the gyro is!! it makes sense now that it senses movement. an aha moment for me.
Fun to see who won the science fair! Very interesting episode.
This is so great, I love those inventions, so creative!
That sounds amazing! I always wanted to play golf.
We just went and played top golf so this is interesting to learn.

Can a science fair project still qualify if the initial hypothesis is proven untrue?
I wanna learn how to build computers someday!
Congrats to all of the science fair winners!
Congrats to science fair winners and the winners of the medals keep working hard and showing people how smart you are.
technology is advancing so quickly
I love learning about cool technology!!!!!
i learned that dimples make golf balls go further
i have always wondered how a computer worked .
I love learning about how my devices work!
technology and computers have advanced so much in the past few years.
technology is so fascinating and cool to learn about!
I’ve learned a lot from these lessons.
Computers are so fascinating!
Cool science projects
It’s so cool how so many tiny machines go into making a computer.
Everyone had cool science projects, the levitation one was awesome
Thanks for teaching us about the CPU and how it works. Also congratulations to all the winners. Great job!
Thank you Mr. Roger Billings.
The way computers work is so cool!
It’s so interesting knowing that computers work like that! such a great live, thank you Acellus <3
Gotta love computers.
It is very creative how Acellus host’s a science fair
My uncle is in the military he’s a Marine. Thank you so much for having the military speak! I want to one day follow in his footsteps and be a Marine. I’ve been studying it for a couple years now, I hope to go into service when I graduate in 2028. 😇
Cool to see how computers work!
The science is just so cool.
Many tiny machines are combined to form a computer. It’s fascinating.
how do you become a astronaut?
This video makes golf balls seem a lot cooler!
The bit about the Lockheed C-130 Hercules was very interesting. Recently I’ve been becoming more interested in aviation and military vehicles. I also did not know that the United States army and Acellus have joined together to created the Willis M. Hawkins Medal of Science.
This was very cool, the complexity of computers can get so interesting!!
how about the movie about drR’s hydrogen jurney
Why do so many people cheat Acellus, and life?
Didnt realize how cool computers are!
Wow! What an interesting video! Does the ball spinning absorb any force and increase the low pressure zone?
Cool video!
wow the science behind this is very interesting
That’s cool how changing the golf ball dimples changes the aerodynamics of the ball!
The science behind golf balls is very interesting.
The fact that you can put tiny gyros in phones is just simply amazing!
It is cool how computers work
This was cool
Computers have come so far and are very complex systems. I wonder what the world would be like if they did not evolve to the level they are now?
Congratulations to all of the science fair winners. Chatgpt is interesting!
This episode was fun to watch!
All the projects are amazing!
The science behind golf balls is really interesting! This explains why some balls are worth a lot more than others.
The world of computers is so complex!
I love watching these videos!! i learn so much!
Amazing Episode!!
So much cool stuff. Congratulation to all the science fair winners.
I ‘m greatful to be able to watch the technology spotlight with Dr. John. It was interesting to learn about the dimples on the golf ball!
I loved learning about computers in this science live video!!
That is cool
Very educational thank you!
Congratulations to the Science Fair winners!
this is so cool to see what goes into making a computer and how they have changed.
Computers are amazing!
I don’t really understand how people were smart enough to figure this out!
Congratulations to the winners!
That carnival looks awesome!
I loved this
i love science
i like all the different projects. i cant wait to do one.
This is so sad that people cheat, it’s just terrible.
I love watching the technology spotlight every week with Dr. john. That was cool to learn about the dimples on the golf ball. I wonder how far each golf ball can go?
Does the Carnival happen every year? Because I’m currently in a treatment facility and would want to attend after I graduate?
(Open for all comments and suggestions please!!😉
Thanks for explaining the transitors.
Thanks Dr. Billings amazing teachings tonight!
The carnival looks so fun!
I never knew how much science went into the creation of golf balls.
wow so cool to learn about I know I couldn’t live without my computer
I cant imagine why people would want to cheat on a program like this. I my self have been struggling with a few of my classes but have recently changed a few of them and find the new ones more interesting, which helps me a lot personally.
Wow, this is super cool this reminds me of when I was younger and I took s.t.e.m. classes after school and I learned how to use circuit boards. I would learn how to turn on lights and give power to the board.
I already knew how all the computer parts work; from the CPU, GPU, RAM, to the SSD, but this video helped me understand them even more!
I think it’s really fascinating how they used a vacuum to change the dimples on the golf ball.
That was awesome.
I have no idea how people could possibly cheat on acellus, but whoever is cheating I know it is bad and that they should know too.
I loved learning about the golf balls and how they are made and how the dimples have an effect on the balls. I do have a wonder though, If you make extremely small dimples in the ball with it change more??🤔
Thank you Dr Roger Billings for having this school in place where people could interact and learn a lot more about education!!!
thanks for all the amazing science lives
Computers are the best!
cool science projects
computers are amazing
First comment! This episode was really good.
I like this lesson
Wow this is amazing!
This was a fun video to watch
I think i might try and make a intergrated circuit.
My brother has built his own computer!
It’s crazy how smart people are, I could never!
I thought it was very interesting how computers work.
That is so amazing that computers work like that!
All of the science fair winners had excellent experiments. The segment about the dimples on golf balls, and how they effect air movement around the ball, was fascinating as was the story of how cell phones detect movement and rotation. Dr Billing’s and R51’s simple explanation of how computers work made it a lot easier to understand.
I love computers!
This is so cool and the ac d2 part is so cute 🥰!
Awesome science projects!
I liked the levitating science project.
I’ve always wondered how they made technology like phones and computers.
These are interesting
The way computers work is really fascinating!
I want to make a computer of my own
Great job everyone! Very impressive

Awesome!
I actually didn’t know that about golf balls! that’s really cool!
Cool video I agree that students shouldn’t be cheating
FIRST POST!!!
I want to make a computer some day!
Wow!
I didn’t know Acellus hosts carnivals! I really want to go!
I was impressed to see how complex some of the science projects were. These other students are kind of intimidating to me–even the ones younger than me. I never saw these types of experiments in my old school. I’m excited to participate in the next event.
This is such a good lesson, thank you Dr. B
My brother is in the Air Force. Thank you for having the military speak today.
Roger Billings has taught me so much
