thank you so much, it helped me. I would be glad if you could make a video of Closed Cartesian categories with exponents and some examples. Thanks.

Good job! Interesting and well-presented.

Hey Catsters

I certainly don't want to complain and very much appreciate the whole category theory-on-video venture. On my mission to watch all of the video, catalogue the concepts used and then place the videos in a partial ordering I have noticed that after Slice and Comma Categories 2 it all goes a bit quiet on the old Slice and Comma Category front. "I am probably not finding it (Slice and Comma 3). Even if it isn't there I don't know why we should EXPECT you to do it. It's not like we're paying you but, you know, you get into these things and questions arise.

Respect

=D

I'm watching these videos one by one at the moment (this is a great pleasure). It strikes me that one can derive an order (in fact a partial order) based on the relation video A "requires content explained in" video A. Of course the playlist on limits is totally ordered on this basis (this doesn't help a great deal; suggesting you watch the playlists in order isn't a great pratical insight). If I am given some encouragement I MIGHT draw a little dependency diagram. I guess this would should the range of different orderings of the material that would be possible if you wanted ideas explained before they were used (admittedly a fairly weak condition but still...).

These videos are collectively the best thing on youtube.

Lots of people see this, I am one of them, and go "Wow, this seems interesting!" But you have no introduction to what the value or function of this is in real life. Can you do a video so that you may introduce viewers to your awesome theory of categories, which is just brimming with potential?

Great Channel! Youtube needs more of this kind of free visual demonstration. I found you from the Haskell site, though some (a ton!) of this is (way) over my head, and i'm not sure where to get started.

Excellent lectures! I have an exam on this stuff tomorrow, and I think these videos have finally helped me understand some of it.

Dear Catsters,

I'm learning (basic) category theory on my own.
Your lectures are a very welcome addition to the textbooks and other media I use to this end. :)
For instance the "fishes"-diagrams (whiskering) in the lecture on natural transformations,
and the string-diagrams, I found very illuminating!

Many thanks!
