Great Basic Introduction to Category Theory
This is a great introduction to category theory for non-mathematicians. If you are a mathematician, you’ll find an understanding of abstract algebra helpful, but ultimately unnecessary. I’ll go grab a more technical introduction with more confidence now.
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 in calculus or linear algebra). Many books talk about the beauty of math, while this one actually makes steps towards actually showing the reader how to appreciate that beauty.
Like many popular books about math, this one actually has very little that goes beyond the 5th grade level, but in examples that are very helpfully illuminating given their elementary …

Like many popular books about math, this one actually has very little that goes beyond the 5th grade level, but in examples that are very helpfully illuminating given their elementary nature. The extended food metaphors and recipes throughout the book fit in wonderfully with the abstract nature of math - perhaps this is why I love cooking so much myself.
I wish I'd read this book in high school to have a better picture of the forest of mathematics.
