“Scanning the next two centuries, we see that the pattern changes dramatically (see page 229). Solo, amateur innovation (quadrant three) surrenders much of its lead to the rising power of networks and commerce (quadrant four). The most dramatic change lies along the horizontal axis, in a mass migration from individual breakthroughs (on the left) to the creative insights of the group (on the right). Less than 10 percent of innovation during the Renaissance is networked; two centuries later, a majority of breakthrough ideas emerge in collaborative environments. Multiple developments precipitate this shift, starting with Gutenberg’s press, which begins to have a material impact on secular research a century and a half after the first Bible hits the stands, as scientific ideas are stored and shared in the form of books and pamphlets. Postal systems, so central to Enlightenment science, flower across Europe; population densities increase in the urban centers; coffeehouses and formal institutions like the Royal Society create new hubs for intellectual collaboration.”
