“In principle, the answer is yes,” said John D. Kubiatowicz, a professor of computer science at the University of California, Berkeley.
“However,” he said, “the amount is very small, on the order of an atogram,” or 10–18 grams. “This amount is effectively unmeasurable,” he went on, since even the most sensitive scales have a resolution of only 10–9 grams. Further, it is only about one hundred-millionth as much as the estimated fluctuation from charging and discharging the device’s battery. A Kindle, for example, uses flash memory, composed of special transistors, one per stored bit, which use trapped electrons to distinguish between a digital 1 and a 0.
