The index entry for Hardy is nearly as long as Ramanujan’s. Key sub-entries include:
1. Relational Networks
The index shows how often Hardy, Littlewood, and Neville appear, reflecting Ramanujan’s dependence on Western mathematicians. Conversely, entries for Ramanujan’s mother (Komalatammal) and wife (Janaki) are sparse, mirroring the biography’s limited domestic focus. the man who knew infinity index
2. Mathematical vs. Human Elements
Mathematical terms occupy many subheadings, but emotional keywords (loneliness, depression, wonder) are few. This imbalance suggests the book prioritizes intellectual history over psychological depth—a known critique.
3. Cultural Contrasts
Entries like “caste,” “vegetarianism,” “English weather,” and “racism” sit alongside purely technical terms, showing how Kanigel weaves social history into the mathematical narrative.
4. Absences as Insight
Notably missing are entries for specific theorems by Ramanujan’s contemporaries (e.g., Mordell) or for Indian nationalists (e.g., Gandhi). This absence indicates the book’s centering on Ramanujan’s personal struggles rather than broad political context. | Period | Key Events | Approximate Chapters
Only 12.9% of entries are mathematical. Key formulas from Ramanujan’s notebooks, such as the Rogers–Ramanujan identities, appear as subentries under “Ramanujan” rather than as main headings. The term “mock theta functions”—Ramanujan’s most profound premonition—receives a single page reference, while “afternoon tea” (under “Cambridge, social life”) receives four. This imbalance raises questions about the intended audience: a mathematical index would invert these priorities.

1. "An equation for me has no meaning unless it expresses a thought of God." under Mother (pages 56
2. "I owe you more than I can say."
3. "The man who knew infinity"
With the release of the 2015 film The Man Who Knew Infinity (starring Dev Patel and Jeremy Irons), the book’s index has taken on a new role. Film viewers use the index to find "scenes cut from the movie."
For example, the film glosses over Ramanujan’s mother (Komalatammal) and her role in intercepting letters. The book’s index, under Mother (pages 56, 89, 277), provides the gritty details the film omitted. Similarly, the index entry for Tuberculosis treatment reveals how horrific his London stay truly was—details sanitized for the silver screen.
