100% bullshit-free textbooks on high school math, vectors, calculus, mechanics, and linear algebra.

Perfect for busy adults.

Better math textbooks

Affordable textbooks with concise lessons that are actually fun to read.


Imagine a single textbook that covers high school math, calculus, and mechanics. Calculus and mechanics are often taught as separate subjects, but this book integrates the two subjects into a coherent whole. Learning mechanics and calculus in parallel is much easier and more interesting.

The book begins with a review chapter on numbers, algebra, equations, functions, in order to make the study of mechanics and calculus accessible for all readers.


This textbook covers all the material of a university-level course through lessons written in a style that is precise and concise. Linear algebra is the foundation of science and engineering.

In the later chapters of the book, readers get a chance to apply their linear algebra skills to solving problems in chemistry, electronics, economics, probability theory, machine learning, computer graphics, signal processing, and even quantum mechanics.

Are you:

a student?

Worried about an upcoming exam? Don't be. The math and physics book will teach you everything you need to know about equations, functions, vectors, forces, momentum, energy, limits, derivatives, integrals, sequences, and series. The linear algebra book will teach you everyting you need to know about liner algebra and its applications.

The books include hundreds of solved problems to help you succeed on your exams.

a self-learner?

Curious to learn math and physics but never had the time? Now's your chance!

Try the practice problems to test your understanding.

a math hater?

Beef up your math skills and get rid of math phobia. Discover a beautiful subject that can bring you tons of knowledge buzz.

Doing math is like playing with LEGO. It's fine if you don't want to play, but you'd be missing out on a lot of fun.

Okay cool but...

A dude who assumes math is difficult.

Isn't math hard?
Programmer who wants to learn from the web.

Can't I just learn math from the web?
A girl who doesn't care about math.

I'm in Arts. I don't care about math.

You can learn math and physics, regardless of your math background.

We've got what you need

Finally, math textbooks that don't suck.

What you're saying:


I'm glad somebody with proper math understanding wrote this excellent piece. The title matches exactly the content—you will not find any boring academic bullshit in this book, but plenty of refreshing learning material about math and physics with charts, diagrams, formulas, and examples.

Wojciech Pietrzak, developer

Compact and funny

It's literally two heavy textbooks packed into a very light and small book. I love the book. My only problem has been when I am working through it in the library and start laughing out loud—you have great examples.

Miriam Aczel, student


Learning calculus in university? You need this book. It's that simple. It is both concise and helpful. For me it was a lifesaver.

Greame Nathan, student

Totally readable

I like the conversational tone of your writing. It's almost like I'm learning math from a friend.

Kevin Del Castillo, developer

Written by a mad scientist

I studied electrical engineering, physics, and computer science at McGill University, tracing the mathematical connections between these subjects.

Tutoring experience

I have more than 15 years of teaching experience as a private tutor, and I've helped many students overcome their fear of math and ace their exams. My teaching strategy focusses on explaining the connections between concepts.

The company

I started Minireference Publishing Co. to bring much-needed changes to the textbook industry. Using open source software and print-on-demand technology, we produce high-quality textbooks at a fraction of the price of mainstream textbooks.
