Although mathematics may seem capable of expressing everything unambiguously, mathematical papers do not always communicate that way in practice.

“Uh, but perhaps we should start persuading mathematicians, uh, to state what they're doing in this formal language because then there's no ambiguity. You see, in, in reality, you, you would imagine that maths was this sort of perfect language where everything can be expressed, you know, in a, in a completely unambiguous way.”

“But in practice, this is not, uh, this is not what happens. In practice, you, you read, you read section three of the paper. In section three it says, "From this point, P will be a prime number which is at least five."”
