Collapsibles are objects that fold out for use and then fold back in again to save space. They include anything from sofabeds to Swiss army knives. Per Mollerup identifies 12 essential principles of collapsibility and looks at examples of each.

The IUTAM Symposium on Flow in Collapsible Tubes and Past Other Highly Compliant Boundaries was held on 26-30 March, 2001, at the University of Warwick. As this was the first scientific meeting of its kind we considered it important to mark the occasion by producing a book. Accordingly, at the end of the Symposium the Scientific Committee met to discuss the most appropriate format for the book. We wished to avoid the format of the conventional conference book consisting of a large number of short articles of varying quality. It was agreed that instead we should produce a limited number of rigorously refereed and edited articles by selected participants who would aim to sum up the state of the art in their particular research area. The outcome is the present book. Peter W. Ca rpenter, Warwick Timothy J. Pedley, Cambridge May, 2002. VB SCIENTIFIC COMMITTEE Co-Chair: P.W. Carpenter, Engineering, Warwiek, UK Co-Chair: TJ.

A translation of a Russian study on pile foundation in collapsible soils, revised and updated for the 1995 English edition. The contents cover such topics as collapsible soils as basis for structures, and designing pile foundations for buildings and structures with collapsible soils.

Collapsing engineering soils are a formidable hazard around the world. These difficult materials also include some of the world's most fertile agricultural soils, fostering dense human populations which are therefore increasingly at risk. Despite an impressive literature on the engineering aspects of collapsing soils, these materials are coming under increasing scrutiny by scientists in other fields. This is most evidently the case with soil scientists, stratigraphers and sedimentologists. Past earth surface conditions have a direct influence on the detailed behaviour of collapsible soils: as a complement, these materials also provide detailed data on changing global climates. The selected papers presented here highlight the common ground between three scientific groups with a vested interest in a better understanding of collapsible soils.

"Rodgrigo Toscano's Collapsible Poetics Theater is a genre-expanding force to be reckoned with. From polyvocalic pieces for multiple readers to 'body-movement poems' to 'simultaneous activities pieces' to anti-masques and plays, these fourteen texts & scores constitute one of the most sustained studies of poetic thinking and action to come in a long time. The question Toscano poses is 'can the poem be tested any further?' "With a cape, confetti and placard, two players and Master of Ceremonies conduct their feints and dodges about concepts of engagement and faith. Has this author been reading the critical social spatiality of Michel de Certeau? The author has certainly been reading poetics, from Mikhail Bahktin's radical linguistics to the controlled clamor of Carla Harryman's dramatic praxis. The art of play has found a talented proponent." --Marjorie Welish, 2008 National Poetry Series Judge
