The Vital Abyss (Expanse, #5.5)

by James S.A. Corey

What astounded me was that the cutting edge of human knowledge was so close. Before I educated myself, I assumed that there was a great depth of science, that every question of importance had been cataloged, studied, that all the answers were there, if only someone could query the datasets the right way. And for some things, that was true.

A thought experiment from my first course in the program: Take a bar of metal and put a single notch in it. The two lengths thus defined have a relationship that can be expressed as the ratio between them. In theory, therefore, any rational number can be expressed with a single mark on a bar of metal. Using a simple alphabetic code, a mark that calculated to a ratio of .1215225 could be read as 12-15-22-5, or “l-o-v-e.” The complete plays of Shakespeare could be written in a single mark, if it were possible to measure accurately enough. Or the machine language expression of the most advanced expert systems, though by then the notch might be small enough that Planck’s constant got in the way. How massive amounts of information could be expressed in and retrieved from infinitesimal objects was the driving concern of my college years. I swam in an intellectual sea of qubits and data implication, coding structures and Rényi entropy.
