THE LIGHT AGES

THE SURPRISING STORY OF MEDIEVAL SCIENCE

An impressive chronicle of human progress.

Expert account of the medieval era’s scientific developments.

A broadcaster, historian, and lecturer at Cambridge, Falk reminds us that scholars no longer consider the centuries after the fall of Rome as the Dark Ages. Rather, “the medieval reality…is a Light Age of scientific interest and inquiry.” The author concentrates on Europe, where literacy was a church monopoly largely confined to monasteries. The greatest of these were wealthy institutions with branches, libraries, and schools whose scholars took part in an international community, which also included Muslims and Jews. Eschewing historical superstars—Roger Bacon makes a few appearances—Falk builds a story around John Westwyk, an obscure 14th-century monk who composed (or most likely copied) manuscripts on astronomical instruments, designed and built others, and traveled widely, making observations along the way. The author makes a convincing case that medieval times produced major advances in technology, mathematics, and education as well as some correct but many more fanciful explanations of natural phenomenon. Important inventions included spectacles, the compass, and Arabic numerals, but almost all of what passed for research confined itself to a single field: astronomy, which had always included astrology and would do so well into the Enlightenment. Fascinated by the heavens, medieval researchers produced precise descriptions of its movements and detected the minuscule variations in the earthly day and year. Much of this was in the service of astrology and the timing of holy days, but it had genuinely practical use in the creation of calendars. Although lacking telescopes, they designed exquisitely complex clocks and astronomical instruments—astrolabes, armillary spheres, equatoriums—that were both impressively accurate and works of art. Falk excels at bringing alive the personalities, theological doctrines, cosmology, and often cutthroat monastery politics of the era, but most readers will prefer to skim the lengthy descriptions of the construction and operation of medieval astronomical devices.

An impressive chronicle of human progress.

A warts-and-all portrait of the famed techno-entrepreneur—and the warts are nearly beyond counting.

To call Elon Musk (b. 1971) “mercurial” is to undervalue the term; to call him a genius is incorrect. Instead, Musk has a gift for leveraging the genius of others in order to make things work. When they don’t, writes eminent biographer Isaacson, it’s because the notoriously headstrong Musk is so sure of himself that he charges ahead against the advice of others: “He does not like to share power.” In this sharp-edged biography, the author likens Musk to an earlier biographical subject, Steve Jobs. Given Musk’s recent political turn, born of the me-first libertarianism of the very rich, however, Henry Ford also comes to mind. What emerges clearly is that Musk, who may or may not have Asperger’s syndrome (“Empathy did not come naturally”), has nurtured several obsessions for years, apart from a passion for the letter X as both a brand and personal name. He firmly believes that “all requirements should be treated as recommendations”; that it is his destiny to make humankind a multi-planetary civilization through innovations in space travel; that government is generally an impediment and that “the thought police are gaining power”; and that “a maniacal sense of urgency” should guide his businesses. That need for speed has led to undeniable successes in beating schedules and competitors, but it has also wrought disaster: One of the most telling anecdotes in the book concerns Musk’s “demon mode” order to relocate thousands of Twitter servers from Sacramento to Portland at breakneck speed, which trashed big parts of the system for months. To judge by Isaacson’s account, that may have been by design, for Musk’s idea of creative destruction seems to mean mostly chaos.

Alternately admiring and critical, unvarnished, and a closely detailed account of a troubled innovator.

GENGHIS KHAN AND THE MAKING OF THE MODERN WORLD

A horde-pleaser, well-written and full of surprises.

“The Mongols swept across the globe as conquerors,” writes the appreciative pop anthropologist-historian Weatherford (The History of Money, 1997, etc.), “but also as civilization’s unrivaled cultural carriers.”

No business-secrets fluffery here, though Weatherford does credit Genghis Khan and company for seeking “not merely to conquer the world but to impose a global order based on free trade, a single international law, and a universal alphabet with which to write all the languages of the world.” Not that the world was necessarily appreciative: the Mongols were renowned for, well, intemperance in war and peace, even if Weatherford does go rather lightly on the atrocities-and-butchery front. Instead, he accentuates the positive changes the Mongols, led by a visionary Genghis Khan, brought to the vast territories they conquered, if ever so briefly: the use of carpets, noodles, tea, playing cards, lemons, carrots, fabrics, and even a few words, including the cheer hurray. (Oh, yes, and flame throwers, too.) Why, then, has history remembered Genghis and his comrades so ungenerously? Whereas Geoffrey Chaucer considered him “so excellent a lord in all things,” Genghis is a byword for all that is savage and terrible; the word “Mongol” figures, thanks to the pseudoscientific racism of the 19th century, as the root of “mongoloid,” a condition attributed to genetic throwbacks to seed sown by Mongol invaders during their decades of ravaging Europe. (Bad science, that, but Dr. Down’s son himself argued that imbeciles “derived from an earlier form of the Mongol stock and should be considered more ‘pre-human, rather than human.’ ”) Weatherford’s lively analysis restores the Mongols’ reputation, and it takes some wonderful learned detours—into, for instance, the history of the so-called Secret History of the Mongols, which the Nazis raced to translate in the hope that it would help them conquer Russia, as only the Mongols had succeeded in doing.

A horde-pleaser, well-written and full of surprises.
