I’ve been a fan of Wired magazine since its inception and boast of having the first issue in my collection.  While Wired quality suffered for a few years, they are fully back on their game.  This month contains and exceptional section by Jame Cameron on exploration.  I’d encourage anyone who can get their hands on a copy to read pages 190-191.  The whole section is fantastic, but that introductory essay is spot on.

<blockquote>Exploration is not a luxury. It defines us as a civilization. It
directly or indirectly benefits every member of society. It yields an
inspirational dividend whose impact on our self-image, confidence, and
economic and geopolitical stature is immeasurable.</blockquote>
