Like the cortex of a human brain. Or the mushroom cloud of a nuclear bomb…these peculiar-looking structures are made of flames stopped in time. To create them, the artist added a few drops of alcohol into a large glass vessel. After a few moments, the volatile substance had spread evenly inside the container. He then ignited the mixture of gases. As the flames traveled through the vessel, they formed into these ephemeral fire sculptures.

DON PETTIT iss star trails
Expedition 31 Flight Engineer Don Pettit relayed some information about photographic techniques used to achieve the images: “My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure.”

GALLERY OF THE UNIVERSITY OF FLORIDA sparse matrix collection
A large and actively growing set of sparse matrices that arise in real applications. The Collection is widely used by the numerical linear algebra community for the development and performance evaluation of sparse matrix algorithms. It allows for robust and repeatable experiments: robust because performance results with artificially-generated matrices can be misleading, and repeatable because matrices are curated and made publicly available in many formats. Its matrices cover a wide spectrum of domains, include those arising from problems with underlying 2D or 3D geometry (as structural engineering, computational fluid dynamics, model reduction, electromagnetics, semiconductor devices, thermodynamics, materials, acoustics, computer graphics/vision, robotics/kinematics, and other discretizations) and those that typically do not have such geometry (optimization, circuit simulation, economic and financial modeling, theoretical and quantum chemistry, chemical process simulation, mathematics and statistics, power networks, and other networks and graphs). We provide software for accessing and managing the Collection, from MATLAB, Mathematica, Fortran, and C, as well as an online search capability. Graph visualization of the matrices is provided, and a new multilevel coarsening scheme is proposed to facilitate this task.

ROBERT KESSELER phy-topic
Extending the long and illustrious history of artists working with flowers and plants, Phytopia reveals a hidden world lying beyond the scope of the human eye. Working in the liminal territory between Art and Science, this extensive collection of images is derived from plant samples; pollen, seeds, fruit and leaves, creating images that lie somewhere between science and symbolism, in which the many complexities of representing plants are concentrated into mesmeric visual statements. Original samples are spluttered with a fine coating of gold and photographed on a scanning electron microscope. The resulting images are re-mastered using subtle washes and layers of colour to enhance their forms and reveal complex and fragile structural characteristics with astonishing clarity. Just as the original plant employs colour coded messages to attract an audience of insect collaborators; through artistic intervention and interpretation KESSELER creates powerful symbols that carry many messages: markers with which we retain contact with the natural world.
ROBERT KESSELER morphogenesis
As a new initiative celebrating the International Year of Biodiversity 2010, the Calouste Gulbenkian Foundation initiated a cross-cultural inter-disciplinary project forming a trans-national network, involving science research, arts and crafts. KESSELER was invited to work with the teams of cellular and molecular scientists in the Instituto Gulbenkian de Ciência in Portugal. Using a variety of microscopy techniques the cellular structures of Portuguese wild flora including a number of rare orchids, reveal complex patterns and structures. Micro-fine sections of the flower stems were stained to expose functional characteristics. Working at a higher magnification than is normally used for whole sections detailed large format images are constructed from up to 500 individual frames.
