Wheeler's 1940 'One-Electron Universe' Idea Shaped Feynman's Physics

Physicist John Wheeler proposed to Richard Feynman in a 1940 phone call that every electron and positron in existence could be a single particle tracing a tangled path back and forth through time. Sections of this path moving forward in time appear as electrons, while sections looping backward appear as positrons. Physicist E. C. G. Stueckelberg independently arrived at a similar concept around the same period.

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.
