I Have Not Failed Ive Just

This saying is attributed to Edison and widely regarded as capturing his attitude toward experimental failure, though the exact wording is a later condensation. Edison's documented statement — made to an associate during his work on a new storage battery — was "I know several thousand things that won't work." The spirit of the remark is authentic; Edison genuinely viewed unsuccessful experiments as data rather than failure, but the polished "10,000" formulation appears to be a later paraphrase.
