__How to Bake Pi: An Edible Exploration of the Mathematics of Mathematics__

What is math How exactly does it work And what do three siblings trying to share a cake have to do with it In How to Bake Pi, math professor Eugenia Cheng provides an accessible introduction to the logic and beauty of mathematics, powered, unexpectedly, by insights from the kitchen we learn, for example, how the b chamel in a lasagna can be a lot like the number 5, andWhat is math How exactly does it work And what do three siblings trying to share a cake have to do with it In How to Bake Pi, math professor Eugenia Cheng provides an accessible introduction to the logic and beauty of mathematics, powered, unexpectedly, by insights from the kitchen we learn, for example, how the b chamel in a lasagna can be a lot like the number 5, and why making a good custard proves that math is easy but life is hard Of course, it s not all cooking we ll also run the New York and Chicago marathons, pay visits to Cinderella and Lewis Carroll, and even get to the bottom of a tomato s identity as a vegetable This is not the math of our high school classes mathematics, Cheng shows us, is less about numbers and formulas and about how we know, believe, and understand anything, including whether our brother took too much cake.At the heart of How to Bake Pi is Cheng s work on category theory a cutting edge mathematics of mathematics Cheng combines her theory work with her enthusiasm for cooking both to shed new light on the fundamentals of mathematics and to give readers a tour of a vast territory no popular book on math has explored before Lively, funny, and clear, How to Bake Pi will dazzle the initiated while amusing and enlightening even the most hardened math phobe.

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 books on the nature of mathematics for the general reader that I ve ever seen.Rather than simply throw mathematical puzzles and diversions at us, or weird and wonderful numbers, Eugenia Cheng takes us on [...]

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 major failing it lacks a further reading section It would be great if such a knowledgeable author could have provided a sign post on where to go next to learn Category Theory If it had an annotated further readin [...]

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 encompassing than merely solving equations She introduces each of her chapters with a recipe involving real food as an analogy to illustrate the points she makes In the early part of the book Eugenia describes how many people find math difficult and drop away at different stages For some, arithmetic is hard For other algebra or geometry [...]

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 themselves for math or its concepts are excellent, and I will steal some next time I teach p.27 if you try and use complicated math for a situation that doesn t call for it, you ll think the math is pointless [...]

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 correctly The book repeats much basic information It bored me and failed to illuminate its subject matter.

The math was a little interesting but the recipes deplorable.

Rambling, boring, and teaches nothing I gave up.

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 when I started the reading.What a disappointment I had Though the author really seems to be bright, and surely does her best to expose herself and her personal life in order to provide real life examples, met [...]

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 forced on me to graduate I bake an thought the connection would bring out the light bulbs in my head The author did a good job of tying in the recipes with a mathematical concept I could see some of what sh [...]

When you cook and bake, you are always looking at the ingredients, so it s easy to forget that the process with which you combine the ingredients is just as important Maths isn t just about numbers and variables, and shapes, and knots, and statements, What you do with them is just as important From the book There are many different ways of combining these simple ingredients flour, butter, and water , and most of them will not result in puff pastry The recipe for clotted cream only has one ingred [...]

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 recommend this to anyone who wants to have a clear picture of what mathematics really is or how it should be properly thought about and practiced hint it s not the pablum you memorized in high school or even [...]

3 stars only because, surprisingly, it wasn t advanced enough for me I really wish it had a bibliography Her website has a few interesting items, though I disagree with her that university lectures are a waste of time at least in the humanities.

Not really about baking, but there are a lot of cool anecdotes that make math sound logical and simple I wish Ms Chen was my high school math teacher, I might have actually cared about it.

really, about 7 10 Good sci pop book, but I would prefer to have condensed version of it

Unfortunately math is not as much like pie or baking as I would have hoped from this title I need someone to read this with me and translate it into english major ese for me.

I have felt for a long time that we teach mathematics, especially in high school, in a way that fails to show what mathematics really is it s not just about numbers, arithmetic, and, by extension, algebra We tend to teach stuff that students do not relate to Two trains start at the same time from Chicago and New York City, and speeds of 30mph and 60mph, respectively How long before they meet Why do we think that students care about such matters, and too often they seem contrived and in this case [...]

I read this to learn how to apply Category Theory to computer programming and came away a little disappointed I expected to become friends with Category Theory, but I feel like I just waved to it on the way to work.But I loved that baking was used as an analogy for math I had never seen even one math baking analogy, but this book has hundreds of them which are at least as illuminating and engaging as any stereotypically male analogy commonly used to illustrate mathematical concepts Makes me won [...]

In the genre of general audience books that attempt to explain math, Eugenia Cheng has written an intriguing and often successful volume Probably than any other undertaking I ve read, Cheng s book wonderfully and clearly describes what doing theoretical mathematics is like especially on the algebraic side She has a nice chapter on the benefits and pitfalls of logic, and she does an excellent job of illustrating the processes of abstraction and generalization, both with her cooking examples and [...]

An extremely engaging celebration and defense of research in pure mathematics For math lovers, Eugenia Cheng, the best young female category theorist in South Yorkshire p 248 , has prepared a tasty morsel on practically every page And for those who aren t math lovers Whatever you think math is let go of it now This is going to be different p 3, emphasis ellipsis original A few examples follow.Flipping to a random page 22 , I find the chapter title Road Signs Abstraction as the Study of Ideal Ver [...]

I read How to Bake Pi in hopes that ingredients, dessert recipes, and baking would help elucidate math for me, and this worked for the most part Some of the food analogies are necessarily a bit forced, and I had trouble relating some of them to the math being discussed, but that was most likely a failing on my part One thing that stands out in Dr Cheng s book is her ability to clearly define and talk about math terms that I ve heard, been taught, used, but never completely understood or perhaps [...]

When I first saw a review of this book it sounded very intriguing Then it took a couple of months to get from the library, and a few weeks to get around to reading it My understanding is that the book was focused on explaining mathematical concepts using reference to food and cooking There are a number of recipes, and recipes are used to explain some broad concepts What I didn t realize is that this book is really about Category Theory of mathematics, or the effort to define math concepts in an [...]

When I read someone else s math, I always hope that the author will have included a reason and not just a proof Eugenia ChengThroughout this book, Cheng attempts to give reasons and not just proofs I do have trouble deciphering proofs and Cheng makes the reader feel comfortable wherever his math has brought him to this point She also has the hallmark of a great teacher she explains the same math several different ways This book is truly accessible whether you have degrees in mathematics or you j [...]

Everyone should read eat this book I can t believe how good this book is for illuminating what mathematics is I have spent most of the past forty five years trying to find the words to communicate what Eugenia Cheng has so masterfully done in this book Whenever I get a chance in the future to talk about mathematics I will steal her metaphors and examples I will also be recommending the book to all of my colleagues in education as well as students I could not stop reading and wondered if she coul [...]

I didn t really like this book.I finished the book in one go with a Starbucks mocha Its a very light read and you can skip a lot of it without losing much My everyday life involves a lot math and category theory so I would often skip an entire section when she explains a concept which I am already familiar with This happened a bit too often in the second half.Her writing is lucid, jokes are funny and some of the references she makes were quite helpful I ended up taking some notes as well I didn [...]

I have less math than science in my educational background but this is a fascinating book If nothing else, it has elevated mathematics in my estimation Honestly, Ching makes the topic intriguing and even edible with recipes included to illustrate points Tavia Gilbert narrates and her voice invites us to appreciate, if not always fully comprehend, Ching s easy to follow points A new genre perhaps math or technical books with recipes The tone is welcoming, the writing style and ideas easy to follo [...]

Jeg er litt streng n , men skal jeg v re rlig var denne fryktelig kjedelig Temaet er matte kombinert med matoppskrifter, men jeg tror jeg rett og slett har blitt for gammel for lese popul rvitenskapelig matte Det g r altfor tregt Ideen er god da, og kanskje er den morsom for folk som ikke kan s mye matte.

The author shows how cooking recipes are similar to mathematics It is a cute way to explore concepts of mathematics, but I thought that it lacked a focus It did not meet my idea of a well written book I believe that the use of a professional editor could have made a significant improvement to this book.

A friendly introduction of category theory and other mathematical concepts for the general public Unfortunately not enough information was presented for me to have a better understanding of what category theory entails the book definitely could benefit from an extra chapter on the topic.

It s been a LONG time since I ve thought about mathematics I enjoyed this author s enthusiasm and her joyful descriptions of math cooking desserts.
