Being taught them and being able to learn them are two completely seperate things. Or did you not learn that? The simple fact is the only way you woulod be able to quantify your statement is to take a group of students from today and teach them as they were taught in 1900 and compare results. Something you can not do.
So as I said you statement stands with out merit.
Ok aft_lizard, you win. Sorry to have troubled you.
