Prelude to Mathematics

by W.W. Sawyer

In this book the emphasis is not on those branches of mathematics which have great practical utility, but on those which are exciting in themselves: mathematics which is strange, novel, apparently impossible. The author not only shows what mathematicians get out of mathematics, but also what they are trying to do, how mathematics grows, and why there are new mathematical discoveries still to be made.

See my review of Mathematician's Delight. Basically, anything written by W. W. Sawyer is pure gold, and worth reading.

Every time I have picked up a W.W. Sawyer book, I have not been disappointed. I mostly regret not having read his books earlier (I started with the last book he wrote, on Functional Analysis in graduate school). Sawyer has a particular mathematical writing style that I find fresh, insightful, and understandable. He uses humor, lots of analogies and pictures, and well-motivated examples to get you to learn a concept. This book is no different, and I plan on going through the rest of the catalog of books written by Sawyer.

This book covers a variety of mathematical topics, from groups to projective geometry, to determinants, and to matrices. You won't be an expert, but you'll have a flavor of what's going on. Sawyer wrote it for people thinking about getting deeper into math, and I think it would work wonderfully there (though I'd like such people to read it and give me feedback), but I have a ton of mathematical experience, and the book shines for me as well. It explains connections between various branches of math, and helps you take a new look at old subjects and just reminds me of the "beauty" (or whatever you want to call it) of math, and learning a math truth for yourself. I particularly enjoyed that Sawyer doesn't dumb anything down. He even talks about the hypergeometric functions (I have an interest in them, since they are basically every function you ever work with in physics) and he explains them without overly complicating things.

There are just a lot of great insights, humorous statements, and wonderful analogies throughout. I am so sad that Sawyer didn't write even more.

The book is very stimulating, and if read carefully you will find that you evolve with it from chapter to chapter. After completing the book, I was compelled to re-read the first chapter "On Beauty and Power". Here Mr. Sawyer states "This book is about how to grow mathematicians." He uses mathematics as a catalyst to show how the universe is constantly seeking balance..."the solution of one problem leads to another problem to be solved", and how we as citizens of the universe must remain open and be willing to see and to grow.

I read this book lying in bed while it was snowing outside. I didn't take notes or write anything. However, I enjoyed this book a lot and learnt a few things from it. It would have been better if I had spent a bit more time reading it. I can always come back and do it again later. I like mathematics and there were many interesting things in this book. It will definitely help me when I read other books on mathematics in the future.

Great wee book.

Parts that I didn’t fully understand but that’s okay.

[Jacob · Rating 3 out of 5]

On general, I really enjoy math books, but I am only giving this one a few stars. The main reasons are its dated-ness (e.g. applications and methods have changed significantly with computers/calculators, encryption, etc.) and that the title and back cover make it sound like a good book for someone with little mathematical background. I would argue that it is geared more for people who already enjoy mathematics and perhaps are thinking about pursuing a degree in the subject. Consequently, the book is too hard for beginners (perhaps expectations of "laymen" with "minimal math background" were higher in 1955?) yet lacking much of the material of interest (e.g. omitted proofs) to more advanced readers.

Padrísimo libro con un final abrupto que no cierra ni siquiera el último capítulo.

El autor se propone y consigue dar una buena zambullida a quienes —como lo hiciera yo en los 90’s— aspiran a convertirse en matemáticos que los familiarice con le elusiva esencia de las Matemáticas.

Cada capítulo es un pequeño tratado pedagógico sobre algún aspecto propio de dicha esencia. Y Sawyer lo explica magistralmente poniendo manos a la obra en una serie de problemas cuya virtud es mostrar las entrañas de alguna rama de las Matemáticas. Hace una mezcla perfecta de 'paper', libro de texto y ensayo introductorio.

Es un libró matemáticamente bello.

*****

Me tardé tanto tiempo en leerlo porque me sobrevino una racha de mal dormir. Inicialmente avancé bastante bien leyéndolo en mis traslados en trolebús, pero al llegar a la mitad comenzaron los problemas. Con trabajos leía un par de páginas antes de ser derrotado por el sueño.

Sin embargo lo disfruté horrores. Y saldé una deuda con aquel jovenzuelo que soñaba con ser matemático, que, atraído por el título y la descripción de la contraportada, compró en la librería de la UAM-I un libro del que, por mucho que le fascinó, tan solo llegó a leer unas veinte páginas.

This was exactly the right book at the right time for me, which is not an experience you can predict for anyone. It covered major branches of mathematics in a few short chapters, nailing down the bases in a few short logical demonstrations, and allowed me to see for myself just how they'd be applicable to modern physics as a whole. As you can tell, I'm a math newbie, but we all had to start somewhere. Sawyer's books are an excellent starting point for anyone.

[Simon · Rating 5 out of 5]

Highly recommended for anyone wanting to understand mathematical thinking processes and how math(s) can become more useful as it becomes more abstract.

Difficult for me to understand

[Giorgi · Rating 3 out of 5]

beginning chapters are more insightful - later ones are more technical
still worth reading

[Douglas Murphy]

that was fun, it's an old book by now but I did find its examples and explanations helpful and, importantly, graspable.

[Debby Slaydon · Rating 3 out of 5]

Hard to follow on a E reader

With an E reader, it was too difficult to flip back and forth among diagrams, new math rules, equations, and results. Being ab engineer, I had a hard time with seeing any value of the new maths beyond “you can” and there might br interesting patterns.

[Ben Gutierrez · Rating 3 out of 5]

This is a bird's eye view of modern mathematics. It touches lightly on a wide variety of things, and is not rigorous. I especially liked the explanation of determinants in linear algebra and the broader sense of how mathematicians think. I felt cheated when I came to the end of the book and realized that my mind hadn't been pushed. Perhaps that was all intentional, since it wasn't Mathematics. It was the Prelude.

Rambled too much

Felt like I was watching a 3b1b video. Amazing!
