It may be no accident that so many of the great scientists really have followed Galileo, in ducking and avoiding the consequences of what they discovered. In the roster of genius, evasion of worldly responsibility seems practically a fixed theme. Newton escaped the world through nuttiness, Darwin through elaborate evasive courtesies and by farming out the politics to Huxley. Heisenberg’s uncertainty was political—he did nuclear-fission research for Hitler—as well as quantum-mechanical. Science demands heroic minds, but not heroic morals. It’s one of the things that make it move. ♦

Language, Darwin believed, was not a conscious invention but a phenomenon “slowly and unconsciously developed by many steps.” But what makes a language a language? In this short animation from TED Ed, linguist John McWhorter, author of the indispensable The Power of Babel: A Natural History of Language (public library), explores the fascinating world of fantasy constructed languages — known as conlangs — from Game of Thrones’ Dothraki to Avatar’s Na’vi to Star Trek’s Klingon to Lord of the Rings’ Elvish. Though fictional, these conlangs reveal a great deal about the fundamentals of real human communication and help us understand the essential components of a successful language — extensive vocabulary, consistent grammar rules but peppered with exceptions, and just the right amount of room for messiness and evolution.
