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.
Richard - the phase diagram approaches that I have come across address the phenomenon of jamming, a behaviour that bizarrely overlaps granular materials, glasses, and foams. I wish that my comprehension of physics was at a level that allowed me to attempt to apply my "explanatory gifts" (thank you for your generosity) to this work. However, once I am faced with "Super-Arrhenius increase of the viscosity" or "data for the colloidal glass transition that can be fit to the Vogel-Fulcher form," then to say that I am out of my depth is a gross understatement. For a resource that at least begins with an accessible introduction to the issues before becoming, at least to me, quite opaque, try Also, by the same group headed by Liu at Penn, see I would be most interested if you would share your level of penetration of this fascinating (but challenging - even to the researchers) topic!

Fethi - thanks for the comment. Unfortunately, being a geologist, I know more about the materials than the methods - architecture and building are not my specialty. I did, however, come across this comment on the famous underground buildings elsewhere in Tunisia, at Bulla Regia: "Particularly interesting is the Bulla Regia unique site where Romans built underground rooms to protect them from the summer heat and cold of the winter. They employed hollow tubes In order to create light-weight overhead vaults (the same technique can be seen in Rome, where amphorae were often embedded into upper walls to make the load much lighter)." A little research along these lines might provide more information on the answer to your question. Michael
1. I agree - don't we have enough golf courses already? Why do we always need more???? 2. Please go ahead. 3. Oops! and many thanks for pointing this out - it's just that old habit of "finish a sentence, put in the period." Now corrected, I hope (.)
Yes, we need a real humdinger of a North Sea storm to illustrate to DT where the true megalomania lies! And I suspect that Scotland's environment laws are perfectly adequate (the proposal was originally turned down) - it's simply that good old human nature and vested interests entered the equation. And on your "unrelated" link, no, I hadn't seen this remarkable news. Another illustration of how sand can help with all kinds of clever stuff - the University of Toronto press release is at Thanks for the link!
