As co-founder of The Idler magazine, Gavin Pretor-Pinney is a longtime advocate of the joys of time ill-spent. In The Cloudspotter's Guide and The Cloud Collector's Handbook, he tackles the idlest pursuit of all: cloudwatching.

Pretor-Pinney’s blend of tranquil appreciation and hard science have floated his cloud books to the top of bestseller lists. For Pretor-Pinney, clouds illustrate how mundane phenomena reveal the complex vectors that connect the natural wonders around us.

Pretor-Pinney is also the author of The Wavewatcher's Companion.
