When you dump a box of jigsaw puzzles on the table, you may not notice it, but you've just started a battle with entropy. And I mean that literally. This simple act actually becomes a very complex process - physical, cognitive and emotional. In this article, I'll show you how putting the puzzle together fits into one of the most fundamental principles governing our world.
1. Entropy - the queen of chaos
In physics, entropy is a measure of the disorderliness of a system. It is most often defined in the context of the second law of thermodynamics, which states that in an isolated system, entropy never decreases. To put it another way: the world naturally tends toward chaos.
So if you scatter a jigsaw puzzle from a closed box onto a table, you create a state of very high entropy - a thousand tiny pieces with no apparent order, scattered randomly. It's a state with many more possible microstates (i.e., ways to arrange the particles) than a finished, ordered picture.
According to Ludwig Boltzmann, who described entropy statistically, the more ways there are to arrange the elements in a given state, the greater the entropy. A puzzle in a box has one ordered microstate (the finished picture) and a huge number of disordered microstates (scattered pieces). This is the reason why the process of puzzle itself can be seen as “reversing the arrow of time”.
2. Puzzles as a cognitive experiment
From the point of view of cognitive psychology, putting together a puzzle is intensive mental work. Research shows that activities of this type engage: working memory - recalling where we have already looked for a similar piece, visual-spatial perception - identifying shapes, colors, patterns, executive functions - planning, strategy, change of approach, cognitive flexibility, concentration and attentiveness - the ability to focus on one activity for an extended period of time.
Interestingly, EEG studies show that brainwave activity resembles a meditative state when putting together puzzles. This is why so many people talk about the “calming” effect of this activity - the brain balances between activity and tranquility.
3. From physics to philosophy - ordering as meaning
In philosophy, entropy is sometimes taken as a metaphor for human life - the chaos of existence that we try to order through culture, language, rituals. Putting the puzzle together is a microcosm of this need: the need to find meaning and order.
As French philosopher Gaston Bachelard wrote, “any place into which we bring order becomes a home.” Puzzles - though temporary and “impractical” - bring us the same comfort: they show us that it is possible to create coherence from fragments.
4. entropy and dopamine reward
From a neuroscience point of view, each moment in which we match an item involves a small release of dopamine, the neurotransmitter responsible for the feeling of satisfaction. This is the so-called dopamine loop: anticipation → action → reward → repetition. Puzzles fit perfectly into this pattern. Each matching piece is a micro-reward that reinforces our commitment.
5. puzzles as an anti-entropy practice
In a world of increasing information, stimuli and distractions, puzzles are becoming an “anti-entropy” practice. They are one of the few experiences that allow us to consciously and tangibly organize something from beginning to end. Without shortcuts. Without chaos. On our terms.
Conclusion: putting reality together
Perhaps this is why putting together a puzzle is so deeply satisfying. It gives us the illusion of being in control of the world - even if only the one laid out on the table. It's a physical manifestation of our need for order, meaning and completion.
Or maybe it's more than that. Maybe putting the puzzle together is a quiet revolution against entropy
