translating preface from Minkowski's "Diophantisce Approximationen"

 The source of all mathematics are integers. This I understand, not only in your traditional sense that the concept of the continuum is albeitet from consideration of discrete quantities. Rather, I think these words on results of recent date. Mastering the exponential function of the number of segments from the acquisition of elliptic functions by means of modular equations can confidently believe that the deepest relationships in the Analysis of arithmetic in nature. This confidence has already paying off.
