About us

The Center of Math was established to strengthen the math community by providing free and affordable resources for all. Focused solely on math, the Center is more than a company - it's a community. Welcome!


Our Story


The Worldwide Center of Mathematics (WCoM) was founded in 2008 by Dr. David B. Massey — a career mathematician and educator of more than 30 years. Its mission: To engage and nurture the local and global mathematics communities. Located in Cambridge, Massachusetts, and focused solely on mathematics, the Center of Math publishes research and other academic resources. Leveraging today’s technology, the Center of Math produces primarily digital resources, including textbooks, videos, research and more.


Quickly, the Center of Math began publishing high-quality, low-cost textbooks, recognizing a severe disservice within the academic textbook market. Committed to affordability and accessibility, our first digital textbooks — the Worldwide Calculus series — set a new standard for quality and value. Center of Math Textbooks now include titles in algebra, calculus, statistics, and more. Working with accomplished authors and world-class partners to deliver the features today’s educators and students have come to expect, we use technology to keep costs low and provide an unprecedented value. True to the mission, free faculty review copies are available upon request and students may skip the markup at the bookstore and buy direct at the Center of Math Store.

Center of Math Videos are produced in the Studio Classroom, a functional, professionally equipped studio classroom and workspace. We welcome local mathematicians to use the space and it’s there we produce lecture and solution videos associated with Worldwide Textbooks, found in each section supplementing the text and exercises. The Center of Math YouTube Channel is home to hundreds of hours of various math-related instruction, lecture, solution, research, test-prep, and entertainment videos. With more than 800,000 views and 8,000 subscribers, the WCoM is an official YouTube Education Partner.

Research at the Center includes the Worldwide Lecture Seminar Series which welcomes world-class research mathematicians to come, collaborate and share their work. Each seminar is digitally produced and made available free to the public. Additionally, the Center publishes the online, refereed Journal of Singularities which is an open-source publication. Want to present at the Center of Math? Contact us.
