All Einstein's work was in physics and mathematics.   If he had conceived of a definitive method of translating Greek into Hottentot, for example, then I would have been staggered.   Absolutely gob smacked.

Did you know that the room that Shakespeare was born in was not identified until the mid-18th Century, in the booming infancy of the Stratford tourist industry?   Is the provenance of that room good enough to convince you that it was the actual room he was born in?   If not, why not?   And yet it would seem that the provenance for our Bill himself, equally shaky, is good enough to be accepted by every schoolboy in the land.   Come on - do explain the difference between the two.
