Their descriptions are highly similar, referring to the nature and behavior of matter and energy at atomic/subatomic levels. While one is labeled 'quantum theory' and the other 'quantum mechanics', these terms are often used interchangeably or 'quantum mechanics' is considered the developed form of 'quantum theory'. The source text (Einstein Biography) uses both terms in contexts that suggest they refer to the same fundamental scientific domain."}}],"ver":3,"created_at":"2026-03-03T20:22:45.613Z","ts":"2026-03-03T20:23:39.854Z","edited_by":{"method":"system","user_id":"01KJ60WNDBKP1GS1XSMJQ9F1AR"}}
