To Infinity and Beyond: A Cultural History of the Infinite
Author: Eli Maor
First published: 1986/1987
Publisher: Birkhäuser; later editions by Princeton University Press
Eli Maor’s To Infinity and Beyond is an accessible exploration of one of mathematics’ most mysterious concepts: infinity. Rather than treating infinity purely as an abstract mathematical object, Maor follows its development through mathematics, philosophy, geometry, art, and cosmology. Beginning with early Greek discomfort with the infinite, he explains how ideas involving limits, infinite sequences and series, irrational numbers, and the infinitely large gradually became legitimate mathematical concepts. A major turning point is Georg Cantor’s theory of infinite sets, which revealed the extraordinary fact that infinities can have different sizes—there are, in a precise mathematical sense, infinities larger than other infinities.
The book then broadens the discussion beyond arithmetic and set theory. Maor examines infinity in geometry, including perspective, inversion, mappings, tessellations, and non-Euclidean ideas, showing how finite drawings can suggest or represent infinite structures. This naturally leads to art, particularly the work of M. C. Escher, whose repeating patterns and transformations provide striking visual representations of mathematical infinity. Maor also explores the relationship between infinity and humanity's conception of the universe, connecting mathematical questions with philosophical and cosmological ones. The result is less a conventional mathematics textbook than an intellectual history of how humans have struggled to understand something that can never literally be reached or completed.
One of the book's strengths is that Maor communicates substantial mathematical ideas without requiring advanced mathematics. Examples such as Hilbert's Hotel, infinite series, geometric constructions, and Cantor's sets make apparently paradoxical properties of infinity understandable. The broader message is that infinity is not simply the symbol $\infty$ or an unimaginably large number. It is a collection of ideas that forced mathematicians to reconsider fundamental notions such as number, size, space, continuity, and even mathematical truth. By connecting those developments with art and intellectual history, Maor makes infinity feel like a cultural achievement as much as a mathematical one.
Key takeaways
- Infinity is not a number in the ordinary sense. Mathematics developed several precise ways of dealing with infinite processes and infinite sets.
- Not all infinities are equal. Cantor demonstrated that the infinity of the real numbers is larger than the infinity of the natural numbers.
- Infinity connects mathematics with art and philosophy. Geometry and the work of M. C. Escher provide especially powerful visual expressions of infinite structures.
- Our understanding of infinity evolved slowly. What earlier thinkers regarded with suspicion eventually became fundamental to calculus, analysis, geometry, and modern set theory.
