like HTML or SQL, the language of database queries.

It can really be a contortion that distorts meaning to try to get C to fit into one of these other tools.

Sometimes abbreviated AU Astronomical Unit .

Finite State Machines, adding a lexer that follows them automatically,

You might think, Boy, is there a context expensive grammar out there? What's the opposite of free?

The set of languages that can be described by re write rules or grammers like this are called context free languages.

The brain is recording all information and driving all change in temporal context.

These grammars that we've been introducing describe something new context free languages.

I spoke at conferences,

What about other countries?

And writing your congressmen is fantastic, they tell you to write your congressman if you want something done.

Units 3 and 4 were relatively abstract to some degree, intentionally so.

Art and literature have always been my passions.

It depends on the context.

This branch of the family is all about representation.

I am just gonna pause for a moment to let you think about that.

In fact, just as we saw that regular languages and regular expressions weren't powerful enough to do everything we needed they couldn't handle balanced parentheses, so we couldn't use them for parsing it's going to turn out that context free languages and context free grammars will only take us so far, and we're going to use additional techniques like interpretation or keeping track of local variables in order to find other things out.

Because in most of the life of the brain this is under control of behavioral context.

So in lecture, we spent a lot of time learning about context free grammars and languages.

But that's an example of an application that also uses this sort of linguistic analysis perhaps a little less related to context free grammars but still in the same vein.

Well, because, sentences are more interesting.

You might use the Let's Begin section to set context for interpreting the video or to define a learning objective for your students.

I would like to kind of zoom in on the moon.

Here I've written down four claims.

Y has the value of 2.

But if right above it I've written X 0, then we'd get a different answer.

It handles LL. It handles LR. It handles LALR.

That line above it is the context.

But this, all of this, is ... academic.

This is called being lazy, and it's a phenomenal virtue when you're writing programs.

So you go and find this paper, and what you find is it is a real piece of science.

You see, for the first time, an imprint on the global level.

There are a number of references to these underneath the lecture videos, but it turns out that a lot of these notions of context free grammars or generative grammars or universal grammars actually came out of psychology or linguistics or computational linguistics to help us understand human and natural language.

Actually, they're both just concise notations for specifying possibly infinite sets of strings.

The figure will be astronomical.

But, someone might argue, that's natural beauty.

... the misspelled word shown in context...

And that, in essence, is how drama emerged as a literary art form.

It turns out that interprocedural data flow analysis is the same problem as, in a theoretical sense, context free language reachability, which is the same problem as could I generate a string in a context free grammar.

All right. So, it's another one of these puzzle like questions.
