The XKCD Thing Explainer book — which explains technical subjects using the thousand most common English words, in the style of Up Goer Five — is due out in November, and Randall Munroe is going out on tour ("book trip") in November!
See him in NYC, Seattle, Beaverton/PDX Oregon, San Francisco, Berkeley, Houston, Naperville/Chicago, and Toronto.
