THE BLIND MEN AND THE ELEPHANT
It was six men of Indostan
To learning much inclined,
Who went to see the Elephant
(Though all of them were blind),
That each by observation
Might satisfy his mind.
|
The First approached the Elephant,
And happening to fall
Against his broad and sturdy side,
At once began to bawl:
“God bless me! but the Elephant
Is very like a WALL!”
|
The Second, feeling of the tusk,
Cried, “Ho, what have we here,
So very round and smooth and sharp?
To me ’tis mighty clear
This wonder of an Elephant
Is very like a SPEAR!”
|
The Third approached the animal,
And happening to take
The squirming trunk within his hands,
Thus boldly up and spake:
“I see,” quoth he, “the Elephant
Is very like a SNAKE!”
|
The Fourth reached out an eager hand,
And felt about the knee
“What most this wondrous beast is like
Is mighty plain,” quoth he:
“‘Tis clear enough the Elephant
Is very like a TREE!”
|
The Fifth, who chanced to touch the ear,
Said: “E’en the blindest man
Can tell what this resembles most;
Deny the fact who can,
This marvel of an Elephant
Is very like a FAN!”
|
The Sixth no sooner had begun
About the beast to grope,
Than seizing on the swinging tail
That fell within his scope,
“I see,” quoth he, “the Elephant
Is very like a ROPE!”
|
And so these men of Indostan
Disputed loud and long,
Each in his own opinion
Exceeding stiff and strong,
Though each was partly in the right,
And all were in the wrong!

I came across that poem to describe what assumptions we do while we create the mathematical model of a physical system. (from the book of Fen, Mühendislik ve Sosyal Bilimlerde Matematiksel Modelleme, Nuri Özalp, Gazi Kitabevi Yayınları, 2015)
That poem example explain so well about our assumptions in mathematical modelling: the model might work for that particular part, however it is not exactly whole. With our mathematical model; We are right , we are also wrong at the same time.However, for engineers the purpose is to make/create something useful for humanity, even though our model is wrong in some part.
