Today, Carrie Anne is going to take a look at how those transistors we talked about last episode can be used to perform complex actions. With the just two states, on and off, the flow of electricity can be used to perform a number of logical operations, which are guided by a branch of mathematics called Boolean Algebra. We’re going to focus on three fundamental operations – NOT, AND, and OR – and show how they were created in a series of really useful circuits. And its these simple electrical circuits that lay the groundwork for our much more complex machines.
*CORRECTION* AT 1:27 the graph says “Quinary System” but then the graph shows 10 possible states – which is actually decimal. Technically, there should be only 5 possible values there, but the overall concept is still the same.

NOTE: Since we can't use annotations in our videos going forward if we find any smallish errors in our videos like this we'll leave clarifications in the episode description. Thanks all for the wonderful feedback! -brandon
Finally i can go play some barotrauma
TSSSSSS

i love mira almuti
Good.
Carrie Anne is the best. So good at explaining these concepts clearly and with a little humour thrown in as well.
Thank you for this incredibly helpful video!
Did not understand XOR gate till this point anywhere. Thanks for the easy explanations
As a beginner with Python, this video blew my mind. Helped the lessons make more sense.
An OR gate with a Smile 😁
"Those aren't the official names but that's how I like to think of them."
I love this series so much lol!
Very difficult way of explanation, I liked the philosophy course
As a CS grad that graduated over 5 years ago, this video had me giggling and remembering many classes, thanks!
IT BECOMES SO CLEAR TO ME!!!
Found my second favorite teacher. My first is Jesus.
For the people who disliked this video, I wonder what they exactly disliked about it….as i couldn't find anything to dislike…..
That was great , precise and more than simple ,thanks.
does anyone else pause the video at the intro just to see the fun facts? no just me alright
Thanks! What a great episode. I still don't get it 100% but I'll keep going 🙂
Bruv, I'm just tryna build a Piston door in Minecraft
That was brilliant, thank you!
Is that a rip-off intro of ted Ed?
Can someone tell me why the nand gate is not shown here?
In the nandgame, the site give it as your first tool to build a circuit.
Well done Carrie 👏🏽👏🏽👏🏽
this sucks i'm forced to watch it
Well done 👍
Haha, that was brilliant. Congrats on the team who thought of this. Amazing!
I love everyone at crash course!
As much as I hate the complexity of these videos, I love how much I'm able to learn from them. And I believe I'm speaking for thousands.
No one wearing pants in the UK
I mean the fact that George Boole came up with Boolean Logic a century before it became a vital component of designing computers is pretty incredible. It just goes to show how the discipline of pure mathematics, that is studying mathematics not for a practical purpose that is known at the time, but just for the sake of expanding the scope of maths itself, can really pay dividends when the technology catches up with it.
what?
and = reverse(inputs) nor
or = reverse(inputs) nand
and = reverse(inputs) nor
BRO HOW I LOVE LOVE THIS COURSE
she talks way too fast !
The Boolean logic to try and use it for philosophy in finding truth reminds me of the logical positivists and their verificationism. It is interesting that it was refuted and not shown to be a tenable position, but it is easy to see why people would hope to find a method that way in search of truth.
I wish I could kiss you angel
THANK YOU, you teach so much better than my teacher.
This made me get more confused some how…
I don't get it ,in xor gate when current doesn't go through the not gate ( when the not gate false) but it goes true then where from the current coming. And. Also in xor gate both A&B are true so the and gate open current true on not gate but it rusult false then where is the current gone. Please help me to find out this
