Die Zahlentheorie ist nützlich, weil man mit ihr promovieren kann.
Translation: Number theory is useful, since one can graduate with it.
Foreword to Vorlesungen über Zahlentheorie (Lectures on Number Theory) (1927).Wir Mathematiker sind alle ein bißchen meschugge.
We mathema­ticians are all a little bit crazy.
quoted by Paul Erdős[1]Please forget everything that you have learned in school; for you haven't learned it.
Foundations of Analysis (1960) as quoted by Eli Maor, The Pythagorean Theorem: A 4,000-year History (2007)Please don't read the preface for the teacher.
Grundlagen der Analysis [Foundations of Analysis] (1930) Preface for the Student, as quoted by Eli Maor, Trigonometric Delights (2013)I will ask of you only the ability to read English and to think logically—no high school mathematics, and certainly no higher mathematics.
Grundlagen der Analysis [Foundations of Analysis] (1930) Preface for the Student, as quoted by Eli Maor, Trigonometric Delights (2013)The multiplication table will not occur in this book, not even the theorem,

2
⋅
2
=
4

{\displaystyle 2\cdot 2=4}
,but I would recommend, as an exercise, that you define

2
=
1
+
1

{\displaystyle 2=1+1}
,

4
=
(

(

{\displaystyle 4=(((1+1)+1)+1)}
and then prove the theorem.
Grundlagen der Analysis [Foundations of Analysis] (1930) Preface for the Student, as quoted by Eli Maor, Trigonometric Delights (2013)My book is written, as befits such easy material, in merciless telegram style ("Axiom," "Definition," "Theorem," "Proof," occasionally "Preliminary Remark")... I hope I have written this book in such a way that a normal student can read it in two days. And then (since he already knows the formal rules from school) he may forget its contents.
