I love learning more about how computers work!
cool live!
This such good information
Hello from Louisiana!
Great information!
Hey from texas!
Hi from Kansas USA.
Congrats on Episode 300!!! That’s a lot of science I’ve learned. Thanks Dr. B and Dr. Monet.
Just because someone hasn’t done it, does not mean it is impossible.
hello science live!
Hi from Texas!
This is soo cool
Hey from Nebraska
I love science live!

I LOVE WEDNESDAY!!!!
Learning about computers is amazing!!!
That looked like my mom’s first computer. :))
Hi from NYC!
Its so interesting that a computer took up so much room , now it fits in my pocket.
Hello Dr. John, what would it take in theory to make this new generation of 3d printers have the capability of constructing larger objects?
Hi from California 👋
Hi, from South Carilina.
Hello from Texas
Computers and the tech that go into them are so interesting! I wouldn’t have known until I watched science lives!
Hi from nevada
my name is Brandon and I liked this live

Hello From Ohio amazing day to watch science live
Thank you! Loved watched Science Live
Hi i am in Puerto Rico right now and it was awesome to learn about the early stage of advanced computer chips!
hiii from Tenneessee
wow science is so cool!
hello from florida
Why would no one buy it if it’s useful?
Hi! From Illinois!
Comment Hi from lombard IL
Hey From Wyoming so exited to be here
Hello from Texas!!
hello from nebraska
Hello from North Carolina!
Hello from the USA
is crazy how we went from floppy discs to what we have now
Hi from Mexico!
Seeing the old computers is very interesting.
Cool!
Good job Dr billings
hey from USA
What materials can you use to 3D print?
the Chinese 3d Printer is so interesting because it uses a laser light!
I love Tobias and Edmond
I think 3D printers are so cool! I could make all kinds of neat things with one.
Imagine we still had those !! So heavy
Hey from Connecticut!!
How did the invention of the personal computer and this processor chip really domino effect modern technology like cell phones and tablets?
I love science live and learning
that computer looks so heavy
Dr. Billings invented a computer!?!
old computers are honestly so fascinating.
That’s cool how the 3D printer can print that fast.
Hi from Texas , very interesting
how’d the Billings computer company turn out? is it still a company?
Hey thanks for this
Hi from Georgia, me and my mom love these lives!
what does cpu mean
I wanted to give a huge thank you for the Social Emotional class it really has helped me through my issue and helped me prepare myself by getting me ready for college next year
hey from Texas
Hello from FL
this is really informative and interesting
Hello from Canada!
Science live is awesome today!! I hope everyone has had a good week!
Did you all realize that this is the 300th episode? That’s crazy!
Wow! That’s so awesome!!
I didn’t know Federico Faggin invented the first microprocessor of the world.
does that mean Mr Billings helped make the first pc
Where did you get the idea for a personal computer?
Hello from va
Hello from NC!
happy to be here tonight!!
This is amazing! That first computer looked cool. I wish I had one. I like old stuff.
hello I’m from maryland
How do the Micro- Processor units get the Names like the C8080?
hello from kansas
Hello from Louisiana
How old was Frederico when he finished the Z80?
Hi from Alabama
WOW Dr Billings! You are living history! SO AMAZING!
I think that the chips that go into the computer has really upgraded since then like the vacuum tube the transistor and so on so on and I’m so excited for the science
I never knew that Dr. B made his own computer. That’s amazing technology for that time!
I love quotes like that!!! It helps when I feel stuck!
hi from NV
Hello from Georgia!
Howdy from Missouri
Im from West Virginia great show!
How well did that computer work compared to the earlier computers?
I love science live!!!!!
the way computer parts got so small kinda so suddenly is really fascinating to me
When was the idea of a computer invented?
how much power does the computer draw from the outlet
Hi from nc
Hey from ga
8000 transistors is a lot!
That’s amazing—being able to continue to create chips that get even stronger and their collaboration is so cool.
Hello from West Virginia, learn something new every time I watch!!
hello from ohio
hello from guatemala
Wait a sceond miss Reabecca is a math teacher too this why I love Science Live so very much
(;(;(;!!
It’s interesting learning about the man who created the chip for the modern computer!!!
