...other great conceptual revolution of the early 20th century. The first step toward quantum theory came in 1900, when Max Planck, working in Berlin, discovered that the radiation from a body that was glowing red hot could be explained if light came only in packets of a certain size, called quanta. It was as if radiation were packaged like sugar; you cannot buy an arbitrary amount of loose sugar in a supermarket but can only buy it in 1-lb. bags. In one of his groundbreaking papers written in 1905, when he was still at the patent office, Einstein showed...
...space bubbles and churns frenetically, an effect sometimes referred to as quantum foam. Pointlike particles, including the graviton, are likely to be tossed about by quantum foam, like Lilliputian boats to which ripples in the ocean loom as large waves. Strings, by contrast, are miniature ocean liners whose greater size lets them span many waves at once, making them impervious to such disturbances...
...energize us; but farming may have originally mattered more as a kind of information-processing technology. By radically increasing the human population that a given acre could support, farming sped up the synergistic exchange of cultural information, lubricating innovation; it packed lots of neurons together, raising both the size and the efficiency of social brains...
Temujin was born clutching a blood clot the size of a knucklebone. His name was war booty, taken from a captive rival by his proud warrior father and tacked on like a medal to his firstborn son. But history echoes with another of his names, a title Temujin would receive 39 years later. In 1206, by acclamation of all the Mongols, he became Genghis Khan, the "Oceanic Ruler" who in the next two decades would father an empire that rolled across Eurasia, linking the Pacific Ocean to the Blade Sea as it amassed kingdoms as loot and nations as slaves...
...golden backdrops with the hills, meadows and houses familiar to 14th century Italians. In those earthly settings he placed three-dimensional Christs and Virgins, saints and sinners, painted as ordinary humans invested with natural emotions. His sweetly weary Madonna locks eyes with the observer as she swaddles a baby-size Jesus...
