Our modern history is defined by the advent of writing. Writing is humankind’s principal technology for collecting, manipulating, storing, retrieving, communicating, and disseminating information. Before we learned to write, we lived in an era referred to as pre-history, or prehistoric times. As humans evolved, began cultivating land, and started living a less nomadic existence, the documentation of events became more sophisticated. Cave drawings gave way to hieroglyphics; stone tablets evolved into scrolls and then into bound books; the invention of typeset documents gave more and more people access to the written word. Today, we can send emails, text messages, and a variety of other digital communication around the world in a matter of seconds. Humans have evolved and documentation has evolved, and with it the way in which we manage calibration.
