Books

Not just for mathematicians and detectives! Learn the basics of logic and its many applications, including advanced testing, constraint solving, function composition, and code proofs. Over 50 exercises and 20 sample programs are included. No prior math background required!

This book supplements the DM for CS Specialization at Coursera and contains many interactive puzzles, autograded quizzes, and code snippets. They are intended to help you to discover important ideas in discrete mathematics on your own. By purchasing the book, you will get all updates of the book free of charge when they are released.

I am a programmer who knows clever tricksI convert integers to bases two to thirty sixBy using character arrays as stringsI can show you amazing math things While others talk about politics and sportsI read about computers of all sortsProgramming languages are all the sameWhen you see arithmetic as a game I don’t write code for a job to be paidBut to understand the video games I playedTo see what works and find out whyTo create, use, study, share, and modify

A complete foundation for Statistics, also serving as a foundation for Data Science, that introduces inference using randomization and simulation while covering traditional methods. Leanpub revenue supports OpenIntro, so we can provide free desk copies to teachers interested in using our books in the classroom. More resources: openintro.org.

Google engineers are regular expression masters. Do you want to become one, too? The Smartest Way to Learn Python Regex transforms you into a regular expression master. The book leverages an innovative learning approach: (1) read a chapter, (2) watch a course video, and (3) solve a code puzzle. It's fun!

How second-order PDEs classify into hyperbolic, parabolic, and elliptic types via characteristics, reduced to canonical forms, and solved explicitly.

How first-order PDEs propagate data along characteristics, from linear to fully nonlinear settings with explicit step-by-step solutions throughout.

The complete formal and technical apparatus of Consciousness-First Cosmogenesis — a modern metaphysical research program treating consciousness as ontologically fundamental. Twenty documents in one compiled volume: seven-layer ontology, category-theoretic mathematical framework, canonical definitions, embodiment architecture, time philosophy, ethics, and unificatory extensions into four applied domains. The technical companion to the CFC trade book.
