WIRED Explainer Revisits Double-Slit Experiment to Illustrate Quantum Weirdness
A WIRED science feature uses the classic double-slit experiment—first demonstrated with light by Thomas Young in 1801 and later with subatomic particles by Claus Jönsson in 1961—to explain why quantum mechanics defies human intuition. The piece argues that while physicists can mathematically predict quantum outcomes with great precision, the underlying behavior, such as particles acting simultaneously like waves and discrete objects, cannot be visualized in everyday terms.
