entanglement

noun

Meaning

A phenomenon where two or more particles become so deeply linked that the state of one instantly influences the other, regardless of the distance separating them. It describes a profound correlation where individual identities merge into a single shared existence.

Etymology

Derived from the Middle English 'tangled', combined with the prefix 'en-' to denote a state of being caught in a web or snare; first applied to quantum mechanics by Erwin Schrödinger in 1935.

Examples

"Imagine two magic coins: if you flip one in London and it lands on heads, its partner in New York will instantly show tails, even without any physical connection between them."

"Physicists use quantum entanglement to create ultra-secure communication lines that can detect even the slightest hint of eavesdropping."
