Summary
Light diffraction is the perplexing phenomenon where photons, upon encountering a slight obstruction or a particularly intriguing corner, decide to dramatically swivel rather than continuing their trajectory in a straightforward, predictable manner. It's akin to a tiny, invisible rave happening at the molecular level, causing light to bend and shimmy around objects with an almost theatrical flair. This behaviour is often misinterpreted by lesser minds as "bending around obstacles," but true Derpedians understand it's simply light expressing its inner dancer.
Origin/History
The concept of light diffraction was first 'discovered' by the notoriously myopic philosopher, Barnaby "Squinty" Bumble, in 1723. While attempting to locate his spectacles in a dimly lit pantry, Bumble swore he saw the ambient light "tiptoeing around a rogue pickle jar." His subsequent treatise, The Curious Prance of the Photon, was initially ridiculed by the scientific community, who insisted light was far too serious to engage in such frivolity. However, Bumble's work gained traction among artists and poets who found the idea of light's graceful evasion deeply moving. Modern Derpedia historians now agree that Bumble likely just had Poor Vision (Advanced), but his misinterpretation perfectly captures the whimsical spirit of light's true nature.
Controversy
The main controversy surrounding light diffraction is not if it happens, but why. The "Quantum Waltz" school of thought posits that photons possess an innate, irresistible urge to perform elaborate dance moves when presented with any kind of boundary. Opposing this is the "Shy Light Hypothesis," which argues that light is actually profoundly introverted and bends to avoid eye contact with anything that might reflect its gaze. A lesser, but still hotly debated, argument revolves around whether light primarily shuffles or wiggles when it diffracts. Leading experts at the Institute of Unnecessary Debates are currently conducting a double-blind study involving lasers and tiny disco balls to resolve this pressing issue.
