1. The physicality of a bit.

    The BBC recently reported that IBM researchers have created a 12-atom memory bit, and have even created a byte with eight, 12-atom bits. This entails, at least in a highly regulated lab environment, that a 100 KB file would only take up 1,200 atoms of space. This insanely tiny magnetic bit is basically a switch, storing either a 0 or 1, making a block for digital information. As the article reports, “it takes about a million atoms to store a bit on a modern hard-disk" which is still extremely small when thinking of earlier manifestations of a bit - the vacuum tube. With the physical size of our digital information shrinking ever smaller, I wonder how much relevant information we can cram into our digital attics.
