Who's #1?
by CARL MEYER
Summary
The post reviews the book “Who’s #1? The Science of Rating and Ranking,” which explores the mathematics behind how we rank things in everyday life—like Google search results, Netflix recommendations, sports teams, and even Amazon products. It explains that the book breaks down different ranking algorithms, often using sports (especially college football) as a running example to show how these systems work and how they can be adjusted depending on what you want to emphasize, such as recent performance or tie-breaking rules.
It also looks at more advanced ideas like combining multiple ranked lists into a single “best” list and measuring how different rankings compare. While the book is praised for being rich in examples and accessible to readers with some linear algebra background, the reviewer notes a minor criticism regarding its treatment of Arrow’s Impossibility Theorem. Overall, the post presents the book as a fun and practical bridge between abstract math and real-world decision-making.
