Che cos’è la matematica e come funziona? Ha qualcosa a che fare con il taglio di una torta? Eugenia Cheng, esuberante professoressa di Matematica Pura all’Università di Sheffield, in questo libro mette a disposizione la sua esperienza di docente per spiegarci la bellezza e la logica di questa disciplina, impastandola – è proprio il caso di dirlo – con la sua forte passione per la cucina e in particolare per la pasticceria: così come per cucinare un dolce è necessario conoscere gli ingredienti e il procedimento, per capire che cosa sia la matematica e fare matematica sono necessari ingredienti – numeri, figure geometriche, operazioni – e capire in che cosa consiste il metodo. Quello che ci spaventa di questa materia è l’astrazione, dunque la Cheng cerca di farci digerire i concetti astratti attraverso l’analogia: attività semplici e quotidiane come cucinare, leggere un cartello stradale, correre hanno molto in comune con numeri primi e dimostrazioni. Così passando da una crema pasticcera a un assioma, da una torta allo zenzero alla teoria delle categorie questa straordinaria e appassionata cuoca/professoressa rende fragrante, desiderabile e cremosa la temibile, spaventosa, algida matematica.

Popular maths books are the most difficult to make interesting to those beyond the hard core readers who are happy to spend their time on mathematical puzzles and diversions, and the reason this book gets four stars despite a couple of problems is that is one of the most original and insightful book Leggi tutto
A very good introduction to what Category Theory *is* and to what mathematics *is*. Lots of helpful examples of concepts, mostly through food and baking. It is important to note that this is *not* a cookery book. It is a book about mathematics that uses recipes for illumination. The book has one majo Leggi tutto
How to Bake Pi by Eugenia Cheng is a fascinating look at mathematics from an atypical perspective. In this work Eugenia shows how math is far larger, varied, and more encompassing than merely solving equations. She introduces each of her chapters with a "recipe" involving real food as an analogy to
Math, bleh. I struggled to get through this. I read it in small increments and almost got excited about math from her level of enthusiasm. I suffer from math trauma and hoped this book could be a possible redo for my math spirit. I was lost in the system at school finishing only what was required (f Leggi tutto
A jargon-free book about category theory? Wow! As a maths teacher with a passion for categories, I really had to read this book. The premise - comparing maths to cooking - and the diagrams inside the text seemed to certify that the essay was both fun and rigorous, so I had pretty high expectations w Leggi tutto
So far, it's a great exposition of the things I love about math, at (what seems to be) a very relatable level for people who don't love math. The style is a bit choppy, often jumping from one metaphor to another without smooth transitions, but still it's an easy and pleasant read. The metaphors thems Leggi tutto
I hoped this book would teach me category theory. The book talked a lot ABOUT category theory but did not give any theorem, nor illustrate with a problem. It is as if it talked ABOUT addition but did not show you how to add 2 numbers, nor give you a summation problem and tell you if you did it corre Leggi tutto
The math was a little interesting but the recipes deplorable.
Rambling, boring, and teaches nothing. I gave up.
While most of the book is material I've known for a long time, it's very well structured and presented in a clean and clear manner. Though a small portion is about category theory and gives some of the "flavor" of the subject, the majority is about how abstract mathematics works in general. I'd reco Leggi tutto
