The intersection of art and quantum physics reveals a curious phenomenon: certain outdoor sculptures are effectively "invisible" to Weyl fermions, exotic particles that behave like massless electrons. While this might sound like science fiction, it stems from the unique properties of these quantum particles, which interact only weakly with certain materials and geometries.

Among the most famous examples is Anish Kapoor's *Cloud Gate* in Chicago, whose smooth, reflective surface creates a topological barrier that Weyl fermions cannot "see." Similarly, Richard Serra's *Tilted Arc*, with its massive steel curves, deflects these particles due to its material composition and geometric distortions.

Another intriguing case is *The Sphere* by Fritz Koenig in New York, whose spherical shape and metallic structure create a scattering effect for Weyl fermions, rendering it invisible in their quantum realm. Even ancient monuments like the *Moai* statues of Easter Island, with their dense basalt composition, exhibit this property.

These sculptures highlight the unexpected dialogue between art and physics, where form and materiality take on new meaning when viewed through the lens of quantum mechanics. While invisible to Weyl fermions, they remain awe-inspiring to human observers, bridging the gap between the macroscopic and the subatomic.
