This is MegaMathematics! grew out of a collaboration between Nancy Casey and Michael Fellows.

Nancy Casey is a writer, editor, and teacher who lives in rural Idaho and publishes short essays online at Planet Nancy. Her series Critical At Any Age carries forward many of the ideas about mathematical thinking and learning at the foundation of "This is MEGA-Mathematics!" She is the author of All the Way to Second Street, a memoir of the back-to-the-land movement. She has worked as a radio news host and is a founder of Recovery Radio.

Michael Fellows has been internationally honored for basic research in parameterized complexity and multivariate algorithmics, as well as for creating imaginative activities to convey the mathematical foundations of computer science to anyone. Among his many awards are the Nerode Prize, Order of Australia Companion to the Queen, and the Humboldt Research Award. He is one of the ten Inaugural Fellows of the European Association for Theoretical Computer Science and most proud to be an Honorary Fellow of the Royal Society of New Zealand, an honor he shares with Charles Darwin, Marie Curie, Albert Einstein, Louis Agassiz, and Max Planck. Not only that, he surfs!!!

Tim Bell is a computer scientist at the University of Canterbury, with interests in computer science education, computer music and text compression. He is a developer of Computer Science Unplugged, a system of activities for teaching computer science without computers. He has coordinated the hosting of This is MegaMathematics! on the Computer Science Unplugged website.

Too numerous to mention are the elementary school teachers and their students from all over the world who experimented with these materials alongside us. Their enthusiasm and creativity have made This is MegaMathematics far richer than we ever imagined at the outset.

The original publication of This is MegaMathematics! was supported by many people at Los Alamos National Laboratory, including Vance Faber, Michael Hawyrlycz, Reid Rivenburgh, and Bonnie Yantis.

Technical support for the first web-based presentation of This is MegaMathematics! was provided by John Dickinson at the University of Idaho.
