Mathematician is a problem solver
As a problem solver
lists strategies to attack the problem and chooses the most appropriate one.
As a problem solver reduces the problem to simpler components and tries to solve each of them separately.
As a problem solver estimates how much progress has been made in the process of coming to a solution.As a problem solver criticizes conjectures and conjectural approaches to solve the problem.
As a problem solver tries to recognize easy from difficult and simple from complicated in the process of coming to a solution.Slide4
1. Deep for a problem solver
Powerful strategies for solving problems are
deep
.Important lemmas which widely appear in the structure of arguments are deep.Those steps in the argument which make much progress are
deep.Conjectures could be deep the same way that arguments could be deep.Deep is simple not complicated; because it can combine with many ideas.
Deep is not always easy. Deep could be difficult.Slide5
Mathematician is a theoretician
As a theoretician
makes assumptions and does repair and surgery of assumptions and theories based on experience.
As a theoretician Tests assumptions and theories.
As a theoretician generalizes of approved assumptions and theories to wider scopes. As a theoretician recognizes the relation between two assumptions or two theories.As a theoretician
compares the strength and weakness of different assumptions and theories. As a theoretician is searching for the truth. Slide6
2. Deep for a theoretician
Deep
are assumptions and phenomena that widely appear.
Deep are a series of related concepts, assumptions or phenomena.Deep assumptions and theories are appropriate for generalizations.
Deep assumptions and theories are strong assumptions and theories. They have many implications.Deep is close to the truth.Slide7
Mathematician is a scientist
As a scientist
communicates and consults with other scientists.

As a scientist tries to control the nature.As a scientist tries to explain and describe the nature.As a scientist tries to solve everyday problems.Slide8
3. Deep for a scientist
It is important for the
deep
to be easily and fluently communicatable.
Deep must be easily discribable.It is important for the deep
to be criticizable. Deep must be divergent.

Deep
is highly evaluated among other
reasonings.Deep correlates given information.
Deep is recognizable from outside the process of solution.It is important for deep to be presentable.In recognition of
deep one correlates local to global, or parts to the whole.Postulates and their natural implications reveal depth of arguments.Slide13
Mathematician is a conjecturer
As a conjecturer
approve assumptions and theories.
As a conjecturer generalize assumptions and theories to wider scopes. By generalization one can unite the realms of two theories. Recognition of relations between assumptions via nice conjectures usually leads to unification of theories. Recognition of relations between theories via conjectures forms a paradigm.
As a conjecturer does surgery on assumptions in order to repair implications.As a conjecturer could unify assumptions and theories by surgery and repair performed by conjectures.
As a conjecturer assesses strength and weakness of assumptions by fluency and naturality
of conjectures.Slide14
6. Deep for a conjecturer
Deep
approves assumptions and theories.

As a teacher tries to communicate with students in a conceptual level.Slide18
8. Deep for a teacher
Deep
could be taught
by conceptualization.Deep is described according to thoughts and perspectives.
Teachind deep concepts needs considering pre-concepts.One should
designe mental excercizes to prepare for teaching deep
.Deep could be communicated with students in a conceptual level.Deep could be a concept.Slide19

studies the causal relations between different diseases.As a physician controls the side effects of diseases and drugs used for curing them.As a physician gives time to the body to be cured naturally.Slide24
11. Deep for a physician
Smaller the scale of pathology,
deeper
the disease.A language which explains the disease more fluently, is deeper
. The deeper the disease is, causal affects are more serious.Deep disease has more side effects.
Deep disease takes more time to be cured naturally.Slide25

Knowledge in the light of depth
Knowledge in the light of
depth is knowledge
in the light of truth.Knowledge is a model of truth.Scientific languages are created to communicate models of truth.Mathematics is a model for the truth.
Only part of the truth could incarnate in mathematics.Evaluating depth of knowledge is evaluation of closeness to the truth.
