Indeed, Richard - and thanks for the links. There is clearly no simple answer to a highly complex problem and California's economy (and the diet of the rest of the US) is fundamentally dependent on agriculture. The question that has to be asked, however, is around efficiency and sustainability - how can California agriculture be re-configured so as not to permanently deplete the state's resources (and export water)? And how can resource use be de-coupled from private vested interests? Not easy to answer... Yes, geodesy helps (as do extremely clever satellite gravity measurements: But these measures are on a regional scale and what the state also needs are the nitty-gritty data of where wells are and how deep they are, how much water is extracted from each well, water level changes in each well and so on. A new law will require some of this - but not for several years. Groundwater extraction in California is a free-for-all and has been for decades.
Vielen Dank! Ihre Sammlung und Bildersind sind wunderbar - Vielen Dank für die Blog-Link. Michael
As usual, Photoshop's magical and mysterious blending options. And thanks for the Marsalis link - wonderful!

You're right - resource efficiency is the key measure. cotton + desert = demise of the Aral Sea
Well, you know that uncertainty as to whether you have left the egg in long enough to be hard-boiled? You're certainly right about time (an eclectic but extensive collection of sandglasses) and, indeed, about empty space. The museum has been described as a "folly", a memorial to the days of Japan's random Government subsidies. But yes, it is handsome, the concept is wonderful - and it does contain art installations ( and and interactive opportunities (see glimpses in, never mind squeaking sand at

Thanks - an interesting update!
Thanks for the update - but it's an update that's really depressing and infuriating! Coastal developers seem to be in a class of their own as far as lobbying, influence and self-interest are concerned.
Really sorry that the sand sample was lost! It seems that the pink dust comes from the iron ore exporting plant - is that correct? It certainly seems to have been an issue for a long time!

Thanks for the comment and questions, Theresa - if it's OK with you, I'll reply by email as soon as I can. Michael
Natalia - thank you! What is your interest in all this? Michael
Suvrat and Richard - many thanks for your comments! And I'll be back to blogging shortly after an involuntary hiatus... Michael
I see it has now changed its name to Sporosarcina pasteurii! Incredibly if you google either name plus "buy" there are places that have it available, presumably for bona fide research. What is your interest?
"Panta rhei" reminded me of the news from earlier this year that "the world's longest-running experiment" had recorded the fall of another drop of pitch (see And "waves running through each other" reminded me of the mysteries of barchan dunes merging and emerging. Then there are physical models of stress in architecture - see Gaudi's catenary models for the Sagrad Familia.... It's all too fascinating - thanks, Richard!
Yes indeed, Richard - another important issue. One of the problems is the significant variation in the rules and regulations from state to state, whether they be financial or operating engineering requirements, public disclosure obligations or regulatory enforcement processes.
Thanks for the link! I read the New Scientist bu had missed this completely - fascinating!
Thanks! And yes, Abbey appears first in the preface and then periodically throughout - a compelling character and writer. And then there's Mary Austin.....

Thanks Suvrat - I'm looking forward to reading it too!

Richard - thanks for this, and particularly for the link to the poem. I hadn't come across it before, and it's wonderful - "The ocean, cumbered by no business more urgent than keeping open old accounts that never balanced . . ." That says it all.
A number of different robotics labs are already working on this - see the linked posts.

Sorry, but I'm not sure what is meant by "abrasive toronto"?!

Yes, indeed, gorgeous photographs of spectacular landscapes! I'll take some of the descriptions from the book: the top image is of salt caravans passing each other "in the enormous Tenere are of the Sahara. The caravan in the foreground is on its way out of the deaert, each camel loaded with 450 pounds of salt, while the one in the background is on its way to the salt mines at Bilma." The cover image is of the "Karnasai Valley, Chad. Pinnacles of sandstone rise through orange dunes a few miles from Chad's border with Libya. During the conflict between the two countries in the 1980s, the entrance to this valley was planted with landmines, which keeps people out of this remote part of the Central Sahara." The third photo is of dunes in Saudi Arabia's Empty Quarter, the great sand seas of the Rub' al Khali. Dunes come in many shapes and sizes, and these are "star" dunes,shaped by more than one dominant wind direction. The last is of the Adjder Oasis, 100 km NW of Timimoun in the Grand Erg (sand sea) of Algeria. "Each of these sand pits, surrounded by dunes, contains a family farm or garden in its hollow. Barriers of palm fronds stop blowing sand from burying these plots.. The recent introduction of electric pumps is rapidly lowering the water level by three feet per year and is endangering this centuries-old system of agriculture." Hope this helps! Go to Steinmetz's website to find many more wonderful images.

Liam - thanks for the comment and the question. However, I fear that my personal expertise in abrasives is very much limited to amateur DIY projects and the occasional rock grinding. I had a look at the site you linked to, and they certainly seem to offer a wide range of high-tech professional products; perhaps worth contacting them directly with your specific needs(although it seems that French is the default language)? I guess one of the challenges is finding a specialist company that deals with individuals versus businesses. What kind of projects are you working on?

Probably not!?
Richard - that link to the article on the CIA and Abstract Expressionism is fascinating, and something I was completely unaware of. It led me to hallucinate a traveling exhibition of NASA's Earth as Art images that would emphasize their complete lack of competition from the legacy of the USSR - an antidote to competitive barbarism. But the idea is, of course, pure fantasy - the likes of Rockefeller and his "Mummy's museum" seem to be in short supply these days.
