6. Musicians can memorize every note
of thousands of songs or long symphonies...
Programmers should be able to commit
entire programs to memory in exact detail.
9. Cognitive Neuroscience
Understanding how the functions of the physical brain
can yield the thoughts and ideas of an intangible mind.
George Miller and Michael Gazzaniga
