“Mathematics catalogues everything that is not self-contradictory; within that vast inventory, physics is an island of structures rich enough to contain their own beholders.”

“My earliest memories are of CP4 — that's a Kähler manifold that looks locally like a vector space with four complex directions, though the global topology's quite different. But I didn't really grow up there; I was moved around a lot when I was young, to keep my perceptions flexible. I only used to spend time in anything remotely like this" — he motioned at the surrounding more-or-less-Euclidean space — for certain special kinds of physics problems. And even most Newtonian mechanics is easier to grasp in a symplectic manifold; having a separate visible coordinate for the position and momentum of every degree of freedom makes things much clearer than when you cram everything together in a single three-dimensional space.”

“Fleshers used to spin fantasies about aliens arriving to ‘conquer’ Earth, to steal their ‘precious’ physical resources, to wipe them out for fear of ‘competition’…as if a species capable of making the journey wouldn’t have had the power, or the wit, or the imagination, to rid itself of obsolete biological imperatives. Conquering the Galaxy is what bacteria with spaceships would do – knowing no better, having no choice.”

“It was almost noon when the plane touched down at the Triad airport on the outskirts of Greensboro. There was a hire car waiting for me; I waved my notepad at the dashboard to transmit my profile, then waited as the seating and controls rearranged themselves slightly, piezoelectric actuators humming. As I started to reverse out of the parking bay, the stereo began a soothing improvisation, flashing up a deadpan title: Music for Leaving Airports 11 June 2008.”

“Parantham finally realized that selecting a star on the map enabled a sub-menu with the unassuming option "Go to star". Choosing this did not change the map's viewpoint or magnification; rather, it caused the map to inquire politely, "Are you sure you wish to travel to this star?”

“A recent survey of 2,000 male graduates of Harvard Business Schoolfound that penis length & IQ were equally good predictors of annualincome. -- from "Eugene”

“It all adds up to normality.”
