Physics begins with an apparent paradox: to understand reality, we often begin by simplifying it.
A physicist may imagine a frictionless surface, a perfectly elastic collision or an ideal gas. These conditions do not perfectly describe the world around us. Yet they are not useless fantasies. They are idealised models that help us understand how real systems behave.
Take the ideal gas. In physics, it is a hypothetical model in which molecular volume and intermolecular forces are neglected. Real gases do not behave perfectly like this under all conditions, but under suitable conditions they can approximate ideal behaviour remarkably well. When pressure becomes high or temperature falls, the differences become more significant, and more realistic models are required.
Why, then, does science retain the idea of an ideal?
Because an ideal provides a reference point.
We compare the real with the ideal. We identify deviations. We investigate their causes. And we try to understand how the real system behaves.
This simple concept from physics offers an interesting way to think about something far beyond science: human character.
The human search for an ideal
Every society has attempted to define qualities that make a person admirable honesty, justice, compassion, courage, patience and humility.
But ideals become meaningful only when they are more than words.
For Muslims, the life of Prophet Muhammad ﷺ represents a lived example of moral excellence. The Qur’an states:
“Indeed, in the Messenger of Allah you have an excellent example…” — Qur’an 33:21.
The Qur’an also addresses the Prophet ﷺ directly, saying:
“And indeed, you are of a great moral character.” — Qur’an 68:4.
Here lies an important distinction. The Prophet ﷺ should not be compared with an “ideal gas” as though he were a theoretical scientific construct. He was a real historical human being whose character was demonstrated in the complexities of real life.
That is precisely what makes the comparison with physics meaningful.
Physics uses idealisation to establish a reference for understanding physical behaviour. Islam presents the Prophetic life as an example for understanding and developing human behaviour.
Ideals are not meant to make us hopeless.There is a common misunderstanding about ideals.
When people hear the word “ideal,” they sometimes think of something impossible and therefore irrelevant.But science does not work that way.
A real gas deviates from the ideal-gas model. That does not make the ideal-gas law meaningless. Instead, the deviation tells us something about the real system. Scientists even develop improved models, such as the van der Waals equation, to account for effects ignored by the ideal model.
Perhaps there is a lesson here for human beings.
Our shortcomings do not make moral excellence irrelevant.We become angry. We lose patience. We make mistakes. We sometimes fail to act according to the values we claim to believe in.
The important question is not whether we will ever become flawless. The important question is whether we are moving towards a better standard.
Measuring the gap
A physicist does not simply say that a real system is “imperfect.” The scientist asks: How much does it deviate, and why?
The same approach can inspire moral self-reflection.
How far is my behaviour from honesty? How far is my response to disagreement from justice? How far is my treatment of others from compassion?
How well do I control anger? How much humility do I possess when I have knowledge, wealth, authority or social status?
These questions turn the Prophetic example from something we merely praise into something against which we examine ourselves. The purpose of an example is not merely admiration. It is transformation.
The lesson of efficiency
Physics also provides another useful metaphor: efficiency.
In an idealised physical system, we can imagine the absence of certain losses. Real systems, however, experience resistance, friction and energy dissipation. Their performance therefore differs from the theoretical limit.
Human beings also experience their own forms of “resistance”: ego, anger, greed, jealousy, fear, impatience and social pressure.
The analogy should not be taken literally—human character cannot be assigned a scientific efficiency percentage. But the underlying idea is valuable.
When a system performs below expectation, we investigate the losses. Perhaps we should do something similar with ourselves.
Instead of simply saying, “I am not a perfect person,” we can ask: What is preventing me from becoming better?
The real test is under pressure
An ideal model is often most useful when we understand where it stops accurately describing reality. Human character, too, is tested not when everything is comfortable, but when circumstances become difficult.
Patience is tested when we are provoked. Justice is tested when the other person is someone we dislike. Forgiveness is tested when we have been wronged. Humility is tested when we possess power. Compassion is tested when helping another person requires sacrifice.
This is one reason the Prophetic example has such enduring significance. It is not merely a collection of statements about morality. It is a life lived through changing circumstances.
The Qur’an’s description of the Prophet ﷺ as an uswah hasanah: an excellent example, therefore points Muslims toward a pattern of conduct, not simply an object of admiration.
From admiration to imitation
There is a difference between loving an ideal and allowing it to influence one’s behaviour.
It is easy to praise the Prophet’s ﷺ mercy while remaining harsh with others. It is easy to praise his humility while constantly seeking recognition. It is easy to speak about justice while becoming biased when the matter concerns someone we dislike.
It is easy to admire patience while becoming intolerant over small disagreements.
The deeper question is therefore not:
How often do we speak about the Prophet ﷺ?
It is: How much of his character is reflected in the way we live?
An ideal gives direction
Perhaps this is where my training in physics offers a personal reflection.
A physicist learns that an ideal model does not have to be a perfect description of every real situation to be useful. It can provide a reference, reveal deviations and point towards a better understanding.
The Prophetic example is fundamentally different from a scientific model—it is a real historical life, not a mathematical abstraction. Yet the idea of a reference point helps us appreciate why an exemplary life matters.
We may never eliminate every weakness from ourselves.We may fail.We may have setbacks.We may fall short of the standard we aspire to.
But the answer is not to abandon the standard.
It is to keep moving towards it.Physics teaches us to ask how closely reality approaches an ideal.The Prophetic example asks us to examine how closely our character approaches the values of mercy, justice, patience, honesty and humility.
Perhaps, ultimately, the value of an ideal is not that everyone reaches it perfectly.
Its value is that it shows us the direction in which we should travel.
And for Muslims, the Qur’an offers that direction through the life of Prophet Muhammad ﷺ: an example to follow, a character to study and a standard against which to examine ourselves.
