CORE DEFINITION

When light (or electrons) passes through double slits, if not observed, it behaves as a wave (producing interference fringes); if observed, it behaves as particles (two stripes). This means that the state of microscopic particles depends on whether they are observed. -

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Physical proof that subjectivity intervenes in objectivity. - This is the physical origin of the 'observer effect'. It profoundly shakes the materialist intuition that 'the objective world exists independently'. In higher-dimensional cognition, it implies that consciousness may not be a bystander of the universe, but a participant. Your momentary thought may indeed collapse the wave function of your life.

anchor

Anchor fast decisions

When light or matter particles pass through double slits, they form interference fringes on the screen, showing wave nature; if 'which slit' is observed, the interference disappears and particle nature appears, revealing wave-particle duality and the influence of observation on quantum systems.
