There is no good reason why the essay should not replace the book, and a lot of good reasons why it should. I am tempted to say — in order to be maximally provocative — that anyone who publishes a book within six years of earning a Ph.D. should be denied tenure. The chances a person at that stage can have published something worth chopping that many trees down is unlikely. I ask you: How are you preparing for the future that could be yours and mine? We — I mean the world in general — don’t need a lot of bad writing. We need some great writing.

From the archive:

Dyson: I'm accustomed to living among very long-lived institutions in England, and I'm always surprised that the rest of the world is so different. At the beginning of Imagined Worlds, I mentioned the avenue of trees at Trinity College, Cambridge. ... Trinity is an astonishing place because it has been a fantastic producer of great science for 400 years and continues to be so.

They planted an avenue of trees in the early 18th century, leading up from the river to the college. This avenue of trees grew very big and majestic in the course of 200 years. When I was a student there 50 years ago, the trees were growing a little dilapidated, though still very beautiful. The college decided that for the sake of the future, they would chop them down and plant new ones. Now, 50 years later, the new trees are half grown and already looking almost as beautiful as the old ones.

That's the kind of thinking that comes naturally in such a place, where 100 years is nothing.

A Call for Slow Writing

For the modern, middle-class North American, “clean” means that you shower and apply deodorant each and every day without fail. For the aristocratic 17th-century Frenchman, it meant that he changed his linen shirt daily and dabbled his hands in water, but never touched the rest of his body with water or soap. For the Roman in the first century, it involved two or more hours of splashing, soaking and steaming the body in water of various temperatures, raking off sweat and oil with a metal scraper, and giving himself a final oiling - all done daily, in company and without soap.

Even more than in the eye or the nose, cleanliness exists in the mind of the beholder. Every culture defines it for itself, choosing what it sees as the perfect point between squalid and over-fastidious.

The United States is trading the long-term health of U.S. research and education for the appearance of short-term security.

A Disturbing Mosaic

There is now an emerging consensus that the United States has entered a recession. In a technical sense, this may or may not be true. Whether the economy will contract for two successive quarters or be considered a recession by some other technical measure, clearly the U.S. economy has shifted its behavior from the relatively strong expansion it has enjoyed for the past six years.

But whether there is a recession now is not the question. Rather, the question should be whether what we are experiencing is a cyclical downturn on the order of 1991 or 2001 — which were passing events — or whether the economy is entering a different pattern of performance, a shift that could last decades. The dread of hidden catastrophe is one thing. Quite another thing is whether the economic expansion that began in 1982 and has lasted more than a quarter-century is at an end.

Atlanta is just as hosed as Munich, but Richard Florida has a new book.

From the best-selling author of The Rise of the Creative Class, a brilliant new book on the surprising importance of place, with advice on how to find the right place for you.

It's a mantra of the age of globalization that where we live doesn't matter. We can innovate just as easily from a ski chalet in Aspen or a beachhouse in Provence as in the office of a Silicon Valley startup.

According to Richard Florida, this is wrong. Globalization is not flattening the world; in fact, place is increasingly relevant to the global economy and our individual lives. Where we live determines the jobs and careers we have access to, the people we meet, and the "mating markets" in which we participate. And everything we think we know about cities and their economic roles is up for grabs.

Who's Your City? offers the first available city rankings by life-stage, rating the best places for singles, families, and empty-nesters to reside. Florida's insights and data provide an essential guide for the more than 40 million Americans who move each year, illuminating everything from what those choices mean for our everyday lives to how we should go about making them.

Who's Your City?

Memeticist Susan Blackmore uses the hotel-bathroom toilet-paper fold as an example of a useless meme -- a meme that has spread throughout the world, even though there is no human reason for it to exist. The persistence of this meme easily disproves the comfortable notion that we humans only spread ideas that are useful or interesting -- it shows that, once a meme takes on life, it spreads itself.

Inspired by Blackmore's research, origamist and TEDster Bruno Bowden created a combinatorial meme -- linking Blackmore's ideas with the sophisticated folding techniques discussed by origami master Robert J. Lang onstage at TED.

The Center for American Progress released a report examining in detail the relationship between slowly growing U.S. mortgage markets, the suddenly aggressive growth of credit card debt, and what both trends could mean to borrowers, their lenders, and global financial markets.

The U.S. credit card market is showing signs of trouble just as the home mortgage crisis surges to unprecedented heights across the United States and throughout the global financial marketplace. Against the backdrop of record-high numbers of home foreclosures, lenders are tightening mortgage lending standards, making it harder for families to maintain their consumption in the face of weakening income growth. At the same time, credit card issuers present their all-too-convenient lending product as a much needed but inevitably dangerous pressure valve for cash-strapped borrowers.
