It is often mentioned that the number theory has applications in computer science, esp. in cryptography. It seems to me that these applications are very few compared to the size of the number theory itself, aren't they? More generally, are there any applications of the number theory that are not in computer science?

I suppose that must depend on what you mean by 'number theory' ?

The calculus of observations

Whittaker and Robinson

Approximation Theory and methods

I suppose it was not serious.
