Propose Axiomatizations:  Based on AM's earlier successes and/or on simulated
real-world situations 

Propose and Prove conjectures:  Using, e.g., the
heuristics discussed by Polya 

INTUITION:
visual analogies to simulated real-world scenarios

AESTHETICS has components of:
Simplicity,
Harmony,
Relating entities which previously seemed disparate,
Elegance,
Promis of later usefulness,
Importance in completing some analogy,
Interrelated in many different ways,
short but theory-laden

PRENUMERICAL Knowledge:
Elementary notions of sets, relations, properties, problems, problem-solving,
methods, proof techniques, analogy; and also some  abilities
to evaluate interestingness, to locate relevant knowledge 

IDEA really means "a ⊗4nonobvious opinion⊗*", and it is very
important to receive criticism of them before the system is actually programmed

⊗2Terms related to Understanding⊗*


UNDERSTOOD means: internally accessable, manipulable, and represented
DECLARATIVE: definition, assertions
DEMONIC: recognizing when it is relevant
OPERATIONAL: knowledge of how to use it
EXEMPLARY: examples, non-examples, and boundary examples
INTUITIVE: abstract but powerful image, opaque simulation
.FILL SINGLE SPACE PREFACE 1 INDENT 0,4,0
PSYCHOLOGICALLY PREREQUISITE field:   One which makes the new field easier
to learn, which contains more concrete analogues of the ideas of the new
field. For example, knowing about geometry makes it easier to learn about
topology, even though topology never formally uses any results or definitions
from geometry. 

FORMALLY PREREQUISITE field:
For example, arithmetic is usually formally based upon set theory,
although most of us learn about them in the other order.
