By The Washington Post | June 10, 2018 at 8:45 am By Cleve R. Wootson Jr. | Washington Post The Leaning Tower of Pisa and its 5.5-degree lean has vexed engineers for centuries. Partially constructed on unexpectedly soft soil, the ancient bell tower began to lean before it was even finished, a historical goof that went on to become one of the world’s historical oddities — and made the tower a UNESCO World Heritage site. How can something so obviously structurally unsound endure in an earthquake-prone region for hundreds of years? People who assemble an IKEA cabinet and have 18 pieces left over don’t expect to pass a wobbly Hemnes down to their great-grandchildren. Professor George Mylonakis wanted to know why. The tower in northwestern Italy has managed to survive two world wars, millions of tourist visits and at least four strong earthquakes that have hit the region since 1280, according to Phys.org. One of those quakes was greater than 6.0 on the Richter … [Read more...] about How Leaning Tower of Pisa has stood up to earthquakes for hundreds of years

Saturday morning in Gaiole in Chianti, a little town in the Tuscan heartland. A summer Saturday. A hint of cool in the air, but the promise of a beautiful day to come. Shopkeepers are raising their shutters and the Bar Centrale is doing a brisk trade in brioches and cappuccinos. Up and down the street, greetings are being exchanged. There’s Italian, of course, but also a lot of English. Dutch and German. But mainly English. Even those not talking give themselves away. By their deck shoes and shorts, you shall know them. They’re here for a coffee, of course, but also to pick up yesterday’s Daily Telegraph, stock up on wine, buy cheese and prosciutto for lunch, maybe grab some fizzy water and a few Peronis for the fridge. All part of the many small things that make up the villa holiday experience, but also a vignette that confirms the cliché of “Chiantishire”, the idea that this tiny area of Italy is so busy with Brits it might as well be the … [Read more...] about Forget Chianti – these are the five hidden corners of Tuscany you must visit
It's a story as old as cities themselves: prosperity comes to town and triggers a building boom. In modern San Francisco, rows of skyscrapers have begun lining the downtown streets and recasting the skyline, monuments to the triumph of the tech sector. Leading this wave, the Millennium Tower. Fifty-eight stories of opulence, it opened in 2009 to great acclaim, then the tallest residential building west of the Mississippi. Though priced in the millions, the inventory of posh apartments moved quickly. Yet for all its curb appeal, the building has, quite literally, one fundamental problem: it's sinking into mud and tilting toward its neighbors. Engineering doesn't often make for rollicking mystery but San Francisco is captivated by the tale of the leaning tower and the lawsuits it's spawned. As we first reported this past fall, it's a story positioned -- albeit at an angle -- somewhere between civic scandal and civic curiosity, an illustration of what can happen when zeal for development … [Read more...] about San Francisco’s leaning tower of lawsuits
