What is mathematics ?!
Science of structure, order and relation Science dealing with the logic of quantity
and shape and arrangement A science of relation Set of tools for solving practical and
technical problems A game for intellectual construction

What do thinkers say about mathematics !
“Nature is written in the language of mathematics”
Galileo“Mathematics is the music of the spheres”
Pythagoras“The world is made up of numbers” Pythagoras

Axiom-theorem Structure
The foundation of mathematics is : AXIOMS ( = collection of fundamental laws)
Formal systems of knowledge
Define Axioms Rules of Inferences
Create Theorems
Create mathematical knowledge

Mathematical truth Mathematics does not seek truth,
but it does seek coherence.

Creative Discipline !
It is a discipline that requires the least effort because it relies on little preliminary knowledge.
It is evolving: Hands on: Pythagoras theorem,
parabolas, hyperbolas, ellipses

Why do we ALL learn mathematics?
Why do we learn literature?
Isn’t it enough to read and write ! Why do we learn biology? history?
music? geology?

Mathematics, what for ?!
Helps researchers of all kinds and in all the domains to understand our world and how it functions
( engineers, biologists, ecologists, …)
Helps citizens in their everyday life

Mathematics offers us
another world, above our natural world.
In fact, our world is very complex whereas the mathematical world seems to be better structured.
In order to do this, we should let go of the complicated rules of our real world and join the coherent rules of the math world.

Mathemagics It is a rather fantastic and exciting
privilege of the science of mathematics that everything that was once thought of and proven still retains its worth intact.
Mathematical theories are for all time

Finally “ when the imagination is
confounded with intelligence, isn’t it mathematics?
Albert Camus
Mathematics honors the human mind

Mathematics: an introduction to
abstraction!"Let no one who is
not a geometer enter".
