Paradigm Shifts

Sous la forme miniaturisée du transistor à triode, l’invention de Lee de Forest devint la cheville ouvrière de notre ère de l’information.

“So often,” says Ian Ross, who worked in Jack Morton’s department at Bell Labs doing transistor development in the 1950s, “the original concept of what an innovation will do”—the replacement of the vacuum tube, in this case—“frequently turns out not to be the major impact.”1 The transistor’s greatest value was not as a replacement for the old but a

Vail persuaded his new board of directors that to solve these problems, the company should create a quarantined group working on “fundamental” research. Like Bush, he understood the need for separating and sheltering radical ideas—the need for a department of loonshots run by loons, free to explore the bizarre. Vail put a physicist from MIT, Frank

Yet understanding the circumstances that led up to that unusual winter of 1947 at Bell Labs, and what happened there in the years afterward, promises a number of insights into how societies progress. With this in mind, one might think of a host of reasons to look back at these old inventions, these forgotten engineers, these lost worlds.
