IC – Divide by 3
How can tiny transistors do math? In this episode of Science LIVE with Roger Billings, discover how integrated circuits use logic gates and on-and-off transistors to multiply, divide, and process numbers. See how a simple “divide by 3” circuit is built—and how millions of these tiny switches working together make today’s powerful computers possible.
Roger Billings also talks about the engineering behind the Falcon 9 from SpaceX. In addition, learn how gallium could be used to generate hydrogen as a clean energy source, highlighting exciting possibilities for future energy innovation.

This is my first science live and I really enjoyed it!
How successful was the stereo when it was first produced?
Science for life
Hello from Oregon! Thank you for providing these videos weekly. They are always so interesting!
Acellus is excellent for mapping out your future. That information was great.
who created LED lights?
This was awesome!!!
Super awesome science live! Never stop doing these!
Science live has a lot of useful stuff to learn
This was my 1st science live and I really enjoyed it!
how does stereophonic sound work?
The Proteges always make me laugh! I love their videos!
science live is so interesting and very fun to watch
Really hoping R51 will achieve his true socional potential.
How long does it take for gallium to become hydrogen
I loved the gallium idea! A idea no one thought would work turned into a hydrogen source! WOW!
a useless metal turned into a hydrogen source is really cool.
Loved the part where they talked about gallium. Was excited to learn that metal can melt at above room temperature. We found it awesome that even when the website is down we can still have access to the school app so I don’t miss a day of school.
r51 is my new math teacher.
i found it amazing how the eyes create the image to our brain and how our ears can caclulate where sound is coming from as well
the next episode is the 300th science live episode!
Happy Friday from San Diego!
The Gallium truly is interesting. And hello from Utah.
R 51 should of stay a little bit longer
I love the creativity in each science live session!
This computer that I am watching this on has it has a stereo speaker system. It sounds like the music and everything is all over the room.
This computer that I am watching this on has it has a stereo speaker system.

My best part of the week
I really loved science live
Surround sounds development is cool, never really thought about the fact that modern theaters are so immersive unlike original theaters.
The optic nerve is so intricate, the human brain really is amazing!
I didn’t expect learning about audio to be so enjoyable! Well done, Tobias!
I love these science lives.
loved the cowboy stand off! keep doing amazing work.
What are gallium isotopes?
This science love was fun! The
Protégés are fun and educational!
I loved the gallium idea! An almost useless metal turned into a hydrogen source?! Impressive.
It’s awesome how a useless metal like gallium can be altered into an entire energy source. Humans are genuinely such interesting creatures coming up with new ways to alter our ways of living.
Science is the coolest! so many things are fascinating
I love the scanner it’s so cool
Signing in from Georgia! I love science live and what you guys do to improve Acellus and learning

how long does is take for gallium to become hydrogen
science live is the best!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Gallium is such an interesting substance I never knew about until today, it’s so fascinating knowing how quickly it can take form in different states!
Happy Friday Acellus Family!!
this has nothing to do with this at all but cool cowboy hat at 37:23
I like her hat.
I didn’t know there was a metal that could dissolve in water.
the best one yet!!!
Science live is the best!!!!!!
hahaha area51 was so funny
I love the proteges
How do you make the bacteria to kill cancer?
Science is so jenuinely interesting to me! I’m excited to see more! 😀
I can’t wait for the next science live episode!!!
Hi from Montana; I enjoyed this weeks science video!
I look forward to this every week!

Gallium is this random metal that’s kinda useless, but now it’s being turned into a hydrogen source? That’s crazy cool!
Science is my favorite!
My grandparents got to watch a live shuttle lift off in Florida many years ago. I would love a chance to see one in person as well! Thank you for another great Science Live!
I like how he demonstrated how some computers work, like clocks
Hey this video was really interesting . i loved the part about the auditory stuff
I feel like watching movies at the theater would be so boring if the sounds only came from one place!
Learning about stereophonic audio was pretty cool!!
All i have to say to the newest inventioneer. GIRL POWWWER! I’ve been waiting to see if the inventioneers would get a girl on the team and my dream came true! Also, i loved today’s video it was pretty cool! ❤️
I loved all the info on the metals! Thanks science live!
i passed my mid term exam im so proud of myself!!!!
Its amazing how the mind can think of such things!
Never would have thought that gallium could be used as a hydrogen source but I am once again shocked at how smart and how much effort you would have to put in to ever find this out!!
The brain is the original computer!!! *
How much does a potential transistor cost?
that division duel was awsome!
This weeks episode was awesome the brain is so cool.
Watching from Alaska this is awesome!!!
The cancer eating bacteria was cool.
I loved the gallium idea
I would probably do the same as Mrs. Pajet. I am right handed, but I can do things with my left hand too.
Congrats on your 300th Science Live video.
This was a really interesting science live!
R51 is hilarious!
These lives are the best !

Watching from KC
Science is one of my favorite subject i love these!
Gallium is so amazing!
I love how they give me ideas i didn’t know were possible
I thought that it was cool that scientists at the universitiy of Waterloo where engineering a bacteria to eat cancer cells and how they made sure that it just targets only cancer cells and not go in to blood cells or other things like that.
it’s really cool that we have the technology to do tests on the human brain to see what we can and can’t do
Hi from Kentucky! i love science!!!
i would love to have a kit or something similar to build those kind of circuits????
hi from georgia, absolutley loved this live thank you for itt!
Love learning about resisters and how they “resist” and slow down energy.
