Oppenheimer on Bohr (1964 UCLA)



I came across this 1964 UCLA talk by Oppenheimer, on his hero Niels Bohr.

Oppenheimer: Mathematics is "an immense enlargement of language, an ability to talk about things which in words would be simply inaccessible."

I find it strange that psychometricians usually define "verbal ability" over a vocabulary set that excludes words from mathematics and other scientific areas. A person's verbal score is enhanced by knowing many (increasingly obscure) words for the same concept, as opposed to knowing words which describe new concepts beyond those which appear in ordinary language.

Is it more valuable to have mastery of these words: esoteric, abstruse, enigmatic, cryptic, recondite, inscrutable, opaque, ... (all describe similar concepts; they are synonyms for not easily understood),

or these: mean, variance, standard deviation, fluctuation, scaling, dimensionality, eigenvector, orthogonal, kernel, null space (these describe distinct but highly useful concepts not found in ordinary language)?

Among the simplest (and most useful) mathematical words/concepts that flummox ordinary people are statistical terms such as mean, variance, standard deviation, etc. One could be familiar with all of these words and concepts, yet obtain a low score on a test of verbal ability due to an insufficiently large grasp of (relatively useless) esoteric synonyms.
