I am so very sad.

On August 24, he resigned. On October 5, he died.

What is this mysterious thing called self-control? When we fight an urge, it feels like a strenuous effort, as if there were a homunculus in the head that physically impinged on a persistent antagonist. We speak of exerting will power, of forcing ourselves to go to work, of restraining ourselves and of controlling our temper, as if it were an unruly dog. In recent years the psychologist Roy F. Baumeister has shown that the force metaphor has a kernel of neurobiological reality. In “Willpower,” he has teamed up with the irreverent New York Times science columnist John Tierney to explain this ingenious research and show how it can enhance our lives.

In the days ahead, a baby will be born who will take the global population above 7 billion for the first time, and in all probability that birth will take place in China or India, the two countries with more than a billion inhabitants.No one is sure. There may already be 7 billion passengers on spaceship earth, as no statistician would be prepared to say exactly when this event of largely symbolic significance takes place.The United Nations has fixed October 31 as the date of the fateful birth, but events have so often proved demographers wrong in the past that the expectation is that it will be sooner rather than later The rate of population growth has soared over the course of recorded history: When Jesus was born, there are thought to have been around 300 million people on earth.

One of the most widely quoted sentences of Sir Francis Bacon—it comes from his essay "Of Studies"—concerns the reading of books: "Some books are to be tasted, others to be swallowed and some few to be chewed and digested; that is, some books are to be read only in parts; others to be read, but not curiously; and some few to be read wholly, and with diligence and attention." This is usually taken as a wise or sententious general comment about the worthiness of various texts, but Ann Blair shows that Bacon was making a very practical recommendation to people who were overwhelmed by the availability of books and couldn't imagine how they were going to read them all. Bacon tells such worried folks that they can't read them all, and so should develop strategies of discernment that enable them to make wise decisions about how to invest their time. I think Bacon would have applauded Clay Shirky's comment that we suffer not from "information overload" but from "filter failure." Bacon's famous sentence is really a strategy for filtering.

At its core, Bayes’s theorem depends upon an ingenious turnabout: If you want to assess the strength of your hypothesis given the evidence, you must also assess the strength of the evidence given your hypothesis. In the face of uncertainty, a Bayesian asks three questions: How confident am I in the truth of my initial belief? On the assumption that my original belief is true, how confident am I that the new evidence is accurate? And whether or not my original belief is true, how confident am I that the new evidence is accurate?
