Anyone who has built a career on managing document-management systems can hardly welcome the claim that documents themselves are the problem. Anyone who has edited Word documents all their working life can hardly welcome the thought that Word itself is a blind spot.

There are five major brain-wave types, each correlating to a different state of consciousness. “Delta,” the slowest brain wave (meaning the one with the longest pauses between bursts of electricity), is found between 1 Hz and 3.9 Hz. When someone is in a deep, dreamless sleep, they’re in delta. Next up, between 4 Hz and 7.9 Hz, is “theta,” which correlates to REM sleep, meditation, insight, and (as is often necessary for insight) the processing of novel incoming stimuli. Between 8 Hz and 13.9 Hz hovers “alpha,” the brain’s basic resting state. People in alpha are relaxed, calm, and lucid, but not really thinking. Beta sits between 14 Hz and 30 Hz, and signifies learning and concentration at the low end, fear and stress at the high. Above 30 Hz there’s a fast-moving wave known as “gamma,” which only shows up during “binding,” when different parts of the brain are combining disparate thoughts into a single idea.
