Genius at Play: The Curious Mind of John Horton Conway
by Siobhan Roberts
Bloomsbury, 2015 (($30))

Mathematician John H. Conway's name pops up all over the mathematics world—group theory, game theory, knot theory, abstract algebra, geometry—and in the pages of this magazine, where he was frequently featured in Martin Gardner's Mathematical Games column. It was there that his most famous creation, Conway's Game of Life—a set of rules for propagating a pattern that generates incredible complexity—made its world debut. Science journalist Roberts's new biography of Conway demonstrates how the man's playfulness and originality has fed into the creativity and intelligence of his ideas. The tome resonates with Conway's voice—which gets its own special font—and his discussions with the author dictate the story's structure and provide the narrative's best glimpses into how his mind darts and weaves.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
