Kindles can load up thousands of books, all without adding any weight as they do so, right? Well ... yes and no.
It seems the leading e-reader — and others — do add weight as they add digital books. A University of California, Berkeley computer science professor says the amount, however is "very small, on the order of an atogram."
“In principle, the answer is yes,” he said.
What's an atogram? The amount, 10–18 grams, or "a unit of mass equal to 0.000 000 000 000 000 001 grams," is "effectively unmeasurable," says Kubiatowicz, as even the most sensitive scientific scales have a resolution of only 10–9 grams.
Now, no matter what fluffy romance or goth novel you're reading on your Kindle, when your friends asking what you're reading, you can just say with honesty: "It's heavy. Really heavy."
