Perception and Action: An Introduction to Clojure's Time Model
Summary
Stuart Halloway discusses how we use a total control time model, proposing a different one that represents the world more accurately helping to solve some of the concurrency and parallelism problems.

need to rewire those neurons for functional programming after years of imperative programming.
This is why Carnegie Mellon is starting freshman with functional programming right off the bat - before their absorbent young minds get infested with imperative thinking.

I realize i'm not enlightened like the rest of you with functional programming.
But it's not that, it's all the other stuff. transactional memory, persistent data structures, ref deref...etc. This guy was shooting a new big keyword every minute and only stop at it for a bit as if they're well understood concepts. Makes me wonder if the purpose of the speech is to teach something or just show off.

That's true - but the talk is specifically about the time model, not really an introduction to Clojure or FP itself.
Check this out for all the transactional memory, ref, deref stuff

But yeah, FP is hard to get your head around - I guess at least as hard as learning OO/imperative the first time around.

Thanks Matthew, I also found the following talk which is about the same subject but better structured.

Contrary to what Faisal said, I found that the time model has very little to do with the concept of functional programming.
Observer should effect the observed?

Well according to quantum theory this is not the case. So if we want to be precise sending a message to an object asking it about its state is more correct model to the world.
