Now where did I put my Einstein-Rosen Bridge?

This $20 kit promises hours of fun for the prospective parallel worlds tourist. Simply by activating your device, you could have your pick of trillions of alternate universes. Then you just have to figure out how to get there. Somehow I don't think Hopstop supports this function yet.

Speaking of alternate universes, I have been getting quite a kick out of Neal Stephenson's Anathem. In a strange version of our own world, a hermetic order called the Discipline are the last to preserve the ways of logic and scholarship when the society around them has collapsed into degeneracy. The history of the planet Arbre is eerily familiar to our own, and yet, wonderfully alien at the same time. Like Stephenson's other works, every page unfolds a new treat for the questing mind. Fans of philosophy, alternate worlds, and the Hitchhiker's Guides will definitely enjoy this book.

Jeff Smith, creator of Bone, has a new title out as well, and this world-hopping adventure is definitely not for kids. RASL is the story of a scientist searching through multiple realities for the woman he loves, or something. I'm still trying to figure it out but I'm having a lot of fun along the way.
