Martin John Callanan of the Slade School of Fine Art at University College London contacted the National Physical Laboratory (NPL) as he wanted to put together an exhibition featuring large images of the lowest denomination coins from around the world.
Petra Mildeova from NPL’s Advanced Engineered Materials Group demonstrated that full colour images could be taken using an infinite focus 3D optical microscope. Five coins were imaged (containing over 400 megapixels), allowing coins of less than 20 mm diameter to be printed as 1.2 m diameter images.
Martin John Callanan described the images as “really stunning” and is exhibiting them at the Galleria Horrach Moyà in Mallorca, Spain, in an exhibition entitled ‘The Fundamental Units‘ (referring to the smallest denomination of coins on display and not as a result of working with NPL, the home of fundamental constants in the UK). He now hopes to enhance his exhibition by imaging a further 161 coins, one from each of the other countries around the world that use them.
The images have attracted interest from the British Museum and were featured by New Scientist as their image of the day on 4 December 2012.
The mapping of large areas at very high resolution is becoming a more regular requirement. In fact, the capabilities of the microscope used to produce the images of the coins were barely stretched, as they were only in 2D. Using the Alicona Infinite Focus optical microscope NPL is able to acquire 3D datasets from large areas, which can be used to study worn surfaces on a gear, drill bit or metal punch and hence produce a detailed measurement of the volume of material lost by wear of the component. Such quantified volume measurements can then be used to determine the best material or operating practice for a given material grade.
Electronic and digital systems generate completely new forms of migration. In the creative arts, new phenomena related to migration and the synergies of disparate systems are emerging. Artistic products evolve from traditional forms into hybrid digital forms. Analog products are being digitized; data spaces are trans-located from one data storage system to another; existing sounds, images, and texts are remixed and fused into new datasets.
The book is based on international conference and exhibition Migrating Reality which took place on April 4-5, 2008 in Galerie der Künste, Berlin, Germany, and on material submitted to the online magazine balsas.cc. As with the conference, the exhibition, and the on-line projects, the book is an overview of the migration topic from various perspectives, not excluding the use of a variety of languages. For example, we offer the reader an interview with Žilvinas Lilas “Bastymasis man būtų daug priimtinesnis žodis” conducted by Vytautas Michelkevičius in Lithuanian and the text “Kulturtransfer in der Frühen Neuzeit – eine andere Realität der Migration” by Philipp Zitzlsperger – an essay on migration from a historians perspective. The ideas presented textually in the book shift back and forth from essays and articles to projects and back to essays. The territories shift from social space to virtual space and eventually land us back in a realm of physical, political, economical, and historical reality.
