In the Imitation Game (biopic of Alan Turing released this weekend), one bright Cambridge mathematician to another discussing solving a mathematical proof:
"Why not use Euler's formula to solve that?" [pronouncing it "you-ler" not "oi-ler"]
OK, so it's a bit smartarse to criticise pronunciation of word that may not be obvious to many non-mathematics inclined people, but it's hardly obscure, and this is a biopic about a mathematician! One on which they spent millions on set design, actors, effects, Keira Knightley's cheekbones, marketing etc. Surely they could have spent a few quid on a least one advisor on the authenticity of the subject matter?
