Thank you for the video, Alex! Good stuff, as always! I just wanted to add that one may use this mnemonic to help them understand a Church numeral in a real-life scenario - a Church numeral is basically the number of times you would apply a function f to value x! x - Church's zero f(x) - Church's one f(f(x)) - Church's two f(f(f(x))) - Church's three

I disagree with you. In the expression about nested function, i.e. lambaX.lambdaY.X it is f(X, f(Y)), wherr f(Y)=X, not f(X,Y). This is a huge difference.

I think you have mistake in explaining : lambdaX.lambdaY.X. you convert it to f(x,y)=x which I think is incorrect shouldn't be f(x)=f(y)=x ?

Maybe it's because I'm not a comp sci student, but I still don't get the purpose of lambda calculus - how does it make life better?
@plasticflower Жыл бұрын
It can be useful when you're coming up with a programming language, to sort of outline what you're planning to implement and have a solid set of rules that you can build on
@Zoey-wy7zj10 күн бұрын
The lambda calculus is important as it represents a model of computation. This is known as the Church-Turing thesis(Everything that can be calculated can be shown to be calculated by either a turing machine or the lambda calculus, as both definitions are equivalent.) If you want to prove that something can or cannot be calculated, then you can make an appeal to the lambda calculus or turing machines.

Cmon, define a simple set of rules, which is so powerful and in essence simple as lamda calculus. With only 3 so incredibly simple rules, to be able to calculate any given computable function is huge.

Your video finally made me understand something I couldn't wrap my head around When you drew out what went where and how things interacted it became so clear Thank you!! Chaining lambda functions is complicated but fun to learn about My first project was to reverse three arguments given to the function (λx.λy.λz.z y x) A B C ⇒ (λy.λz.z y A) B C ⇒ (λz.z B A) C ⇒ C B A
