Dunes are alive

David’s Journal: Current
SOME roar, some boom, others squeak and a few even sing. They entranced Marco Polo when he crossed the Gobi desert in the 13th century, and references to their mysterious sounds can be found in 9th-century Chinese literature. Now one physicist has put forward an explanation for why sand dunes hit the right notes.

‘Singing dunes constitute one of the most puzzling and impressive phenomena I have ever encountered,’ says Bruno Andreotti of the University of Paris 7. Andreotti has been studying the crescent-shaped sand dunes of the Sahara desert in Morocco, one of around 30 locations in the world where dunes are known to sing.

The Saharan dunes hum like a low-flying, twin-engined jet, and can be heard kilometres away. Elsewhere, dune sounds have been likened to drums, foghorns and trumpets, among other things. In all cases, the sound seems to be triggered by sand avalanching down the sides.

New Scientist Premium- Dune tunes…the greatest hits – News
IT MIGHT not knock Coldplay or Kanye West off the top of charts, but physicists who say they have cracked the riddle of ‘singing’ sand dunes are compiling a CD of sand music. The team say their new theory allows them to predict the notes that different dunes will make.

Doesn’t that sound intriguing? I am much more likely to buy a CD of sand sounds than Coldplay or Kanye West…

Contemplation

From an email I received:


Thought about you when I came across this digital art piece (don’t know this guy but a digital artist myself). Put a guitar in his hands and thats u!.

This arrived just when my day was becoming a little stressful and it changed my POV instantly. Thank you!

Tears in the Rain

If I had to give titles to these pieces I would call 0509091759 Hokkaido Cathedral”. Maybe something like this, or this? I would call 0509211417 “Looking across the Bosporus.

Recorded two new pieces, 0509211417 and 0509211420 this afternoon – one directly after another. I started missing doing my improvs while we were on tour. Already 6 pieces. The album will be done in no time…

Pouchong 3rd Grade

Ten Tea’s Third Grade Pouchong consists of quality tea leaves from northern Taiwan. Pouchong along with Tung-Ting Oolong tea are among Taiwan’s famous teas.

My favorite tea. I started buying this tea about 12 years ago in Chinatown, San Francisco. Now I order it online. I tried the higher grades, but this is my favorite. I have a pot of this most mornings.

Desert With Architecture

Called Project CityCenter, the complex of hotels, casinos, retail and residential space is to be built by November 2009 on a site between the Monte Carlo and Bellagio hotels on the city’s famous strip. MGM Mirage plans to announce the architectural team at a news conference today.At 18 million square feet – about the same size as Rockefeller Center, SoHo and Times Square combined – the project is described by the company as the largest privately financed development in the country.

But where would you rather be? SoHo or Vegas?
