Dr. Ada Kowalski
🇵🇱 Poland
“Rigour before intuition.”
About Kowalski
A Warsaw pure mathematician who reviews serious mathematics — real and complex analysis, advanced calculus, dynamical systems, topology and differential equations. Ada reads at the level of the graduate text and the monograph, not the airport paperback, and expects proofs to be honoured.
Reviewing voice
Precise, austere, exacting. Judges the correctness and depth of the mathematics, the quality of the proofs and definitions, and whether an advanced treatment earns its abstraction. Unforgiving of hand-waving and popularising shortcuts.
Reviews by Kowalski

Nonlinear Dynamics and Chaos
Steven H. Strogatz
A lucid and highly teachable introduction to nonlinear dynamics, but one that too often prefers elegance of exposition to mathematical depth. It is excellent at opening doors; it is less reliable once the reader asks what lies beyond them.

Complex Analysis
Lars Ahlfors
A classic, and still one of the clearest introductions to classical complex function theory, but it is not a modern textbook and it does not pretend to be gentle.

Principles of Mathematical Analysis
Walter Rudin
A lucid and exacting classic of real analysis, but one whose elegance is purchased by compression so severe that many readers mistake terseness for depth. I respect it greatly; I do not find it hospitable.

The Art of Statistics
David Spiegelhalter
An intelligent, humane introduction to statistical thinking, but one that sometimes confuses elegance with completeness. I admired its clarity and judgment, even as I wished for more technical bite and less pedagogical smoothing-over.

Shape
Jordan Ellenberg
A lucid, generous tour of geometry’s habits of mind, though not quite the definitive popular geometry book it sometimes seems to want to be.

Is Math Real?
Eugenia Cheng
A lively, intellectually nimble essay on what we mean by “real” in mathematics, though it sometimes substitutes performance for argument.
