Chudnovsky-Ramanujan pi Context
Later algorithms for pi build on the modular world opened by Ramanujan's 1/pi series rather than being his own work.
This is a contribution-family entry; no single canonical formula is asserted here.
What Ramanujan Discovered
Chudnovsky-Ramanujan pi Context belongs to the Phase 2 contribution catalogue of major Ramanujan discoveries, named results and formula families. The entry avoids claiming that all 3,900 notebook results are individually transcribed.
Catalogue Position
This entry sits in Formulas for pi, one of the 37 Phase 2 contribution areas.
Reading the Entry
Formula panels show canonical notation where available. Broad families are grouped editorially rather than expanded into unsupported individual notebook entries.
How to Study This Entry
Start with the statement above, then compare its category with nearby entries in the archive. Use the formula permalink when a canonical expression is available, and follow related discoveries to see how the idea connects with partitions, q-series, modular forms, continued fractions, or number theory.
Difficulty is marked as advanced, and the editorial status is needs-review. Records marked for review preserve the contribution but await tighter primary-source citation.
