Preface
1 The Ubiquitous Infinity
1.1 Infinitely many numbers and infinity in numbers

1.3 Infinity concealed: from areas inside circles to logarithms
1.4 ∞, 0, and nothingness in analysis
2 Sets, Functions and Logic: the building blocks
2.1 Sets and relations
2.2 Functions
2.3 Basic logical concepts and operations
3 Infinities: infinitely many of them!
3.1 Bijections, cardinality and Hilbert's hotel
