One of the selling points of the Kindle and other e-readers is that you can carry around thousands of books without adding an ounce to your load. Though this statement is still technically true, a computer scientist at the University of California, Berkeley, has discovered that these e-books actually do weigh something.
The scientist discovered that if you were to literally add thousands of e-books to your e-reader the large amount of data would add an inconsequential, yet still measurable unit of weight to your device. It’s a unit of measurement called an atogram, which is the equivalent of about 0.000 000 000 000 000 001 grams, according to the scientist.
We know, our brains are hurting too. Your hands and wrists will never notice the difference with that many zeros, but it is nevertheless interesting to know that those e-books do, technically, weigh something.
