Here in France, we were taught from fairly early on about Averroes and Avicenne (Ibn Sinna) for instance. There may geographical and societal reasons for these differences, but all in all that's besides the point i was trying to make, which is :
The average person may have heard of Newton, Darwin and others, but how many could really explain the theory of gravity or that of evolution without getting at least some of it wrong?
("Gravity... ha yes, the guy with the apple","evolution... sure, we all are descended from apes, right?")
...Therefore, relying on what the average person may know to discuss whether something is publicly acknowledged and understood is perhaps the wrong way to go about this.
