SICP

lisp seems interesting.

Prerequisite

mit-scheme

# use mit-scheme or chicken scheme compiler

brew install mit-scheme
brew install chicken

I really appreciate the quote MIT guys put at the end of each interpretation.

./eval.sh <FILE_NAME> # mit-scheme
csi -s <FILE_NAME>    # chicken

I think I can start trying to understand knuth and latex after reading 1.3.4
exercise 1.44 is really good
"higher-order procedures enhance the power of our language by enabling us to manipulate, and thereby to reason in terms of, general methods of computation" SICP p108
"elements is said to be closed under an operation ... We do not use the word “closure” in this second sense in this book." SICP p134
THe word nil is a contraction of the Latin word nihil, which means "nothing".
exercise 3.20 is good
"The fact of concurrent execution, either because the world operates in parallel or because our computers do, entails additional complexity in our understanding of time." SICP p403
"Buridan argued that a perfectly rational dog placed between two equally attractive sources of food will starve to death, because it is incapable of deciding which to go to first." SICP p424
footnote 19 & 20 on SICP p523,524
