Oesch answered that he looks at such distant smudges every day. Sure, they’re part of the universe, he said. But consider the abstraction (thought I). A few exhausted photons of light from GNz-11 dropped on a photoelectric detector aboard a satellite orbiting Earth, produced a tiny electrical current that was translated into 0s and 1s, which were beamed to Earth in a radio wave. That information was then processed in data centers in New Mexico and Maryland and eventually landed on Professor Oesch’s computer screen in Geneva. These days, professional astronomers rarely look at the sky through the lens of a telescope. They sit at computer screens.
But not only astronomers. Many of us invest hours each day staring at the screens of our televisions and computers and smartphones. Seldom do we go outside on a clear night, away from the lights of the city, and gaze at the dark starry sky, or take walks in the woods unaccompanied by our digital devices. Most of the minutes and hours of each day we spend in temperature-controlled structures of wood, concrete, and steel. With all of its success, our technology has greatly diminished our direct experience with nature. We live mediated lives. We have created a natureless world.
Relying on new geochemical techniques for analyzing ice core sediment to determine the dates of ancient volcanic activity down to the year or even season, the paper, published in Nature in 2015, showed that major eruptions worldwide caused precipitous, up-to-a-decade-long drops in global temperatures. Later research pegged those drops at as much as 13 degrees F.
What stunned Manning, an Egyptologist, was that the paper recalibrated earlier chronologies by seven to eight years, so that dates of the eruptions neatly coincided with the timing of well-documented political, social, and military upheavals over three centuries of ancient Egyptian history. The paper also correlated volcanic eruptions with major 6th century A.D. pandemics, famines, and socioeconomic turmoil in Europe, Asia, and Central America. The inescapable conclusion, the paper argued, was that volcanic soot—which cools the earth by shielding its surface from sunlight, adversely affecting growing seasons and causing crop failures — helped drive those crises.
Skeptics have seized on the rapid development of the vaccines — among the most impressive feats of medical science in the modern era — to undermine the public’s trust in them. But the breakthroughs behind the vaccines unfolded over decades, little by little, as scientists across the world pursued research in disparate areas, never imagining their work would one day come together to tame the pandemic of the century.
"The Speckled Beauty" is a very Southern story — the devotion to mother, the wild dogs, the biscuits, the snakes, the red dirt and the ornery mules — but in a broader way it is universal, a story of loyalty, love and redemption.
There’s something undeniably gratifying about an elegantly crafted morality tale — and the business reporter Christopher Leonard has written a good one, even if you suspect that the full shape of it isn’t quite as smooth as he makes it out to be. “The Lords of Easy Money” is a fascinating and propulsive story about the Federal Reserve — yes, you read that right. Leonard, in the tradition of Michael Lewis, has taken an arcane subject, rife with the risk of incomprehensibility (or boredom), and built a riveting narrative in which the stakes couldn’t be any clearer.
