How do Lego and Meccano differ as models of reality?
Based on the provided texts, Lego and Meccano serve as distinct metaphors for how we model and interact with reality. They represent a fundamental divergence between idealized structure (Lego) and material engineering (Meccano).
Here is how they differ as models of reality:
1. Digital vs. Analogue (The “Fit”)
• Lego is Binary (Digital): Lego is described as “basically digital” or “almost computer-like.” Connections are binary: pieces either fit 100% or they do not fit at all[1],[2]. It represents a “frictionless computer world” where the messiness of reality has been cleaned up[3].
• Meccano is Analogue (Messy): Meccano is described as “analogue.” It is full of connectors that allow for “slippage and fudging.” The design gets you halfway there, but you often have to “bodge to completion”[2]. It forces the user to deal with the frustrations of the “world of atoms”[4].
2. Tolerance and Friction (The “Truth in Inconvenience”)
• Lego Shields from Reality: Lego minimizes “tolerance stacking” (the accumulation of microscopic errors). It encapsulates complexity, shielding the user from “real-world messy phenomena”[5],[6]. If a Lego model fails, it is usually a gross error in logic or instruction, not a failure of the material[6].
• Meccano Exposes Reality: Meccano teaches the “truth in inconvenience.” It exposes the user to “tolerance stacking,” where tiny misalignments accumulate to prevent the final assembly from fitting together[5],[4]. It forces the user to deal with friction, torque, and material distortion, distinguishing “design knowledge” (the plan) from “reality knowledge” (the physical execution)[7].
3. Architecture vs. Engineering
• Lego Models Architecture: Lego is the superior model for understanding Architecture and Emergence. Because the parts are standardized and reliable, the focus shifts entirely to the structure. The “Bratislava Radio Tower” thought experiment uses Lego to demonstrate how a specific arrangement (structure) allows a system to store potential energy and exhibit properties (like an inverted pyramid) that transcend the properties of individual bricks[8],[9]. It illustrates how structure dominates material[10].
• Meccano Models Engineering: Meccano is the superior model for Engineering. Sir Harry Kroto (Nobel Prize winner) is quoted arguing that Meccano teaches a “feel for materials”—knowing how much to tighten a screw without stripping the thread[11]. It teaches how to manage constraints and forces in a way that the “forgiving” nature of Lego does not[11],[12].
4. Atoms vs. Molecules
• Lego uses “Molecules”: Lego often provides pre-assembled complex parts (like wheel assemblies), effectively encapsulating complexity into “molecules” so the user doesn’t have to build them[6].
• Meccano uses “Atoms”: Meccano requires building everything from scratch using basic “atoms” (strips, plates, nuts, and bolts), forcing the user to understand the construction of the components themselves[1].
Summary
In the author’s view, Lego represents a “clean,” low-friction world of Ordered Complexity where architecture and logic reign supreme. Meccano represents the Real World of “dirty” domains, where friction, tolerance, and material properties act as constraints that must be actively managed through skill and “bodging”[13],[12],[2].
