Too Good Not to Pass Along (...from Jim Holt)

For Sunday reflection, from Jim Holt's fabulous new volume, "When Einstein Walked with Gödel":

"As for space and time, according to current speculative theories they, too, could well have a discontinuous sand-like structure on the tiniest scale, with the minimum length being the Planck length of 10^-33 centimeters and the minimum time being the Planck time of 10^-43 seconds (exactly the time, it has been observed, that it takes a New York cabbie to honk after the light turns green)."

(p.s.... over at MathTango this morning there is a new interview)
