Progressing through AIMA I've just been exposed to agents using propositional logic. I've noticed that worlds and states are framed in such a way as to require a set of axioms to be given first, and then inference can take place.

Is it possible to have a naive agent which forms hypothesis based on percepts that were not hard-coded as axioms? Does anyone know of any work involving this question?

Designing electronics is generally cumbersome and expensive -- or was, until Leah Buechley and her team at MIT developed tools to treat electronics just like paper and pen. In this talk from TEDYouth 2011, Buechley shows some of her charming designs, like a paper piano you can sketch and then play.

mikejuk writes "Long before the current crop of MOOCs (Massive Online Open Course) there was a course that taught you all you needed to know about computers by starting from the NAND gate and working its way up through the logic circuits needed for a computer, on to an assembler, a compiler, an operating system, and finally Tetris. Recently one of the creators of the course, Shimon Schocken, gave a TED talk explaining how it all happened and why it is still relevant today. Once you have seen what is on offer at you will probably decide that it is not only still relevant but the only way to really understand what computers are all about."
