Program
A program might be defined as coded or prearranged information that controls a process (or behavior) leading it towards a goal. The program contains not only the blueprint of the goal but also the instructions of how to use the information of the blueprint. A program is not a description of a given situation but a set of instructions. (p. 128)
Adaptedness thus is an a posteriori result rather than an a priori goal seeking. For this reason the word teleological is misleading when applied to adapted features (p. 131)

A kilobyte rewritable atomic memory
Kilobyte atomic memory. STM image (96 × 126 nm, I = 2.00 nA,V = +500 mV, T = 1.5 K) of a 1,016-byte atomic memory, written to a passage from Feynman’s lecture ‘There’s plenty of room at the bottom’. The various markers used are explained in the legend below the images. The memory consists of 127 functional blocks and 17 broken blocks, resulting in an over all areal density of 0.778 bits nm−2.
