A very popular quote attributed to Albert Einstein but did he really say it? If so, what is the original document containing the original explanation of it?
The quote "An alleged scientific discovery has no merit unless it can be explained to a barmaid." is popularly attributed to Lord Rutherford of Nelson in as stated in Einstein, the Man and His Achievement By G. J. Whitrow, Dover Press 1973. Einstein is unlikely to have said it since his theory of relativity was very abstract and based on sophisticated mathematics.
The short answer is: probably no he didn't say this quote. There is no citation supporting this claim.
Another unsourced variants:
But if you open page 418 of Einstein: His Life and Times (1972) by Ronald W. Clark, it says that Louis de Broglie did attribute a similar statement to Einstein:
