“The types of photographs we post need ground rules as well. For example, it is wise to make sure no personally identifying information is accidentally put into a photograph. This includes things like license plates on your cars, the names of your kids’ schools, or your home address. Permission should be sought before posting a photo of someone else. In the case of minor children, this is even more important. It is not fair to them to create a digital trail of their lives that is publicly accessible without their input.”

“A’isha, al-Hasan ibn ‘Ali, Abu Sa‘id al-Khudri and others described him. They said that he would work in the house with his family. He would delouse his clothes, mend his sandals, serve himself, sweep the house and hobble the camel. He would take the camels to graze and eat with the servants. He would knead bread with them and carry his own goods from the market.”

“Sophie Germain had taught herself calculus at a young age. The daughter of a wealthy family, she had become entranced by mathematics after reading a book about Archimedes in her father’s library. When her parents found out that she loved mathematics and was staying up late at night to work on it, they took away her candles, left her fire unlit, and confiscated her nightgowns. Sophie persisted. She wrapped herself in quilts and worked by the light of stolen candles. Eventually her family relented and gave her their blessing. Germain, like all women of her era, was not permitted to attend university, so she continued to teach herself, in some cases by obtaining lecture notes from the courses at the nearby École Polytechnique using the name Monsieur Antoine-August Le Blanc, a student who had left the school. Unaware of his departure, academy administrators continued to print lecture notes and problem sets for him. She submitted work under his name until one of the school’s teachers, the great Lagrange, noticed the remarkable improvement in Monsieur Le Blanc’s previously abysmal performance. Lagrange requested a meeting with Le Blanc and was delighted and astonished to discover her true identity.”

“As he deployed his forces, Newton imposed the same empirical rigor on his new job as he had with his pendulums and prisms. The Mint could not operate any faster than his men could spin their capstans, and every other step had to be timed to match the work of his presses. So Newton watched to “judge of the workmen’s diligence.” He saw how quickly the brutal effort needed to turn the press wore out its team. He observed just how nimble the man loading blanks and pulling finished coins from the press had to be to keep his fingers. Eventually, he identified the perfect pace: if the press thumped just slightly slower than the human heart, striking fifty to fifty-five times a minute, men and machines could stamp out coins for hours at a time. By autumn, Newton had the Mint’s output up to £100,000 every working week—a century ahead of Adam Smith, and more than double again before Henry Ford showed the world just how powerful time-and-motion rigor could be. Newton continued to drive his horses and men for the next two and a half years until the nation’s entire silver money supply had been remade. In all, under his command, the Mint recoined over £6 million—£6,722,970 0s. 2d., to be exact. As that last tuppence indicates, Newton, having spent the whole of his prior life as an essentially solitary thinker, proved to be a truly extraordinary administrator, bringing the effort home with accounts accurate to the penny and stunningly free of corruption.”
