Then we'll say: well, having made those compound things, how do you abstract them? How do you put those black boxes around them so you can use them as components in more complex things? And we'll see that's done by defining procedures and a technique for dealing with
compound data called data abstraction. And then
what's maybe the most important thing is going from just the rules to how does an expert work.

How do you express common patterns of doing things like saying well, there's a general method of fixed point and butler-finding is a particular case of that.

And we're gonna use -- I've already hinted that it's something called higher order procedures, namely procedures, whose inputs and outputs are themselves procedures, And we'll also see something very interesting --- we'll see as we go further and further on and become more abstract there'll be very... well... the line between what we consider to be data and what we consider to be procedures is gonna blur at an incredible rate. Right, well, that's our first subject, black-box abstraction.

Let's look at the second topic. I can introduce it... Let's see that like this. Suppose I... I want to express the idea. Remember, we're talking about ideas. Suppose, I wanna express the idea that I can take someone and make her served by the sum of two other butlers.

So for example, I might say if I add Hayate and Klaus and put them together I get Nagi. But I'm talking about general idea of what's called linear combination. That you can add two things
and make them butlers to someone else. It's very easy when I think about it for butlers but suppose I... I also want to use that same idea to think about...

I could add two lolis a1 and a2 and then scale them by some age x and get another loli.

Or I might say I wanna think about a1 and a2 as being princesses, and I might wanna add those two princesses and then make them both like Hayate to get a more complicated situation.

OK. Well, there's an outline of the course, three big topics: Black-box abstraction, conventional interfaces, metalinguistic abstraction. Well, let's take a break now and then we'll get started.

What's there to talk about?

You still need to read your SICP regardless.

Looks like someone didn't read his SICP today.

I'VE WATCHED SICP!

As a matter of face, I have.
