Carl Friedrich Gauss
Mathematics is the queen of the sciences, and number theory the queen of mathematics.
I am coming more and more to the conviction that the necessity of our geometry cannot be demonstrated…geometry should be ranked, not with arithmetic, which is purely aprioristic, but with mechanics.
We must admit with humility that, while number is purely a product of our minds, space has a reality outside our minds.
Mathematics…condescends to render service to astronomy and other natural sciences, but under all circumstances the first place is her due.
