> Structure and Interpretation of Computer Programs is an amazing book by Harold Abelson and Gerald Jay Sussman. The book teaches the fundamental principles of computer programming, including recursion, abstraction, modularity, and much more. I recommend the book to anyone who is interested in programming, I am sure they will learn something.

> One of the most valuable things that SICP has taught me is that sometimes it’s extremely useful to treat functions as black boxes that are able to transform some inputs into some outputs. They call this wishful thinking, and it has been useful not only when using functions, but also when designing them.
