Thak you both, it was SICP, I finally found the article http://thecleancoder.blogspot.com/2010/08/why-clojure.html http://thecleancoder.blogspot.com/2010/08/why-clojure.html And this is the paragraph that pop in my head today: On page 216 they introduce a concept so familiar that most programming books start with it. On page 216 they prove to you that you've had some wrong ideas about programming all along. On page two hundred and sixteen, after talking about algorithms, data structures, recursion, iteration, trees, high-order procedures, scoping, local variables, data abstraction, closures, message-passing, and a plethora of other topics -- after all that, they introduce assignment! To clarify: I havent read SICP, I donw know LISP, but I am attracted to Clojure. I am puttint SICP to my to.read list right now. And also this to my to.watch list http://groups.csail.mit.edu/mac/classes/6.001/abelson-sussman-lectures/ http://groups.csail.mit.edu/mac/classes/6.001/abelson-sussma...
