       Plasma Table Elle Starkman and Andrew Post-Zwicker Princeton Plasma Physics Laboratory FIRST PRIZE WINNER A dust cloud of silicon micro-spheres that was illuminated by laser light scattering from the cloud is suspended in a plasma. The dust cloud is approximately 0.5” high and floats in a conical shape between the dust tray and an electrode as long as the plasma is maintained. Fundamental dust cloud properties and dynamics have applications from plasma processing to space plasmas.

 Driven Anton Darhuber, Benjamin Fischer and Sandra Troian Microfluidic Research and Engineering Laboratory, Department of Chemical Engineering SECOND PRIZE WINNER This image illustrates evolving dynamical patterns formed during the spreading of a surface-active substance (surfactant) over a thin liquid film on a silicon wafer. After spin-coating of glycerol, small droplets of oleic acid were deposited. The usually slow spreading process was highly accelerated by the surface tension imbalance that triggered a cascade of hydrodynamic instabilities. Such surface-tension driven flow phenomena are believed to be important for the self-cleaning mechanism of the lung as well as pulmonary drug delivery. |

 Individually Marked Ants Stephen Pratt Department of Ecology and Evolutionary Biology THIRD PRIZE WINNER Ant colonies show remarkably coordinated behavior, despite lacking any direction from a well-informed central controller. Each worker instead applies simple decision rules to limited knowledge, and exchanges information with her neighbors using rudimentary cues and signals. From this process emerge the construction of complex nests, collective decisions among food sources, the adaptive allocation of labor across tasks, and many other group accomplishments. To identify the underlying decision rules requires a detailed description of the behavior of individually identifiable ants. The ant species Temnothorax curvispinosus is especially useful for this kind of study, because they form small colonies of only a few hundred workers, and they thrive in thin, glass-walled laboratory nests, facilitating detailed video records of their behavior. Most importantly, as shown in these images, workers can be individually marked with tiny drops of paint. Ants are first immobilized with carbon dioxide, and then marked with a distinctive pattern of four drops. They soon emerge unharmed from narcosis, and retain their marks for several months to years. This approach has been particularly useful in showing how emigrating colonies can choose the best among several new homes, even when few individual workers are aware of all the options under consideration. |

 Mooney Faces Aaron Schurger GS Department of Psychology In 1957 Craig Mooney, a cognitive psychologist, published “Age in the development of closure ability in children.” He used images similar to the ones above to test the ability of children to perform “perceptual closure”—that is, to form a coherent perceptual impression on the basis of very little visual detail. Images of this type, often referred to as Mooney faces, have become common in cognitive psychology experiments because they offer a means of inducing variable perception with constant visuo-spatial characteristics (the images are very often not perceived as faces if viewed upside down). I have used such images in an experiment I conducted with a “blindsight” patient, to test for signs of face perception without awareness. I used many of Mooney’s original 40 images, but also created a few hundred of my own (with the help of my wife, Corinne Foy). Along the way, I have come to appreciate many of the images as being very pleasant to look at. It is fascinating to notice how little visual information it takes to experience a face (humans have evolved very effective and efficient mechanisms for the perception of faces), and at the same time to notice the variety of other shapes and contours that emerge. |

 Ontogeny Recapitulates Phylogeny Claire Filloux '07 Department of Physics Evolutionarily, to be human is ordinary and incredible. In eight weeks after fertilization, a single human embryo traces our entire evolutionary past. The first weeks we start simple, a sponge maybe, or the translucent ghost of a hydra. Within the next few days a notochord descends. The origin of the vertebrate. Gills streak our sides by week four, and we begin to breathe the amniotic fluid of our mother’s uterus like an ancient jawless fish. Week five, our hands web into the ray-like fin of a perch. Then a spine. A red lattice of veins. A mouth that sucks fluid into the soaked lungs of something amphibian. Week seven we sprout the first hair follicles of a mammal. Only in week eight are we human. We can never escape our ancestry because we play it back in ourselves. But with the same neurons that make a kingfisher dive or a deer start at the fall of a footstep he feels foreign, we can marvel as the whole living kingdom rises in a single human cell. We are not special because we can look down on other forms of life, but because we can see the connection. A deer looks into our eyes and sees a stranger. We look into the eyes of a deer and see ourselves. |

 The Average Princetonian Clay Bavor '05 and Jesse Levinson '05 Department of Computer Science The Average Princetonian is composed of about two dozen so-called templates, or average representations of facial features that are used by computer algorithms to identify points on a face. We created these templates by combining photos of 150 Princeton students with a piece of software we wrote as part of our senior thesis. |

 Ex Plures Adveho Unus Clay Bavor '05 and Jesse Levinson '05 Department of Computer Science “Ex Plures Adveho Unus” (“Out of Many Comes One”) is composed of images from our senior thesis. The top three faces are the average Princeton male student, average Princeton student, and average Princeton female student. The bottom five images are processed representations of differences between faces which are used in algorithms for identifying facial features. We created these composite images by combining photos of 150 Princeton students with a piece of software we wrote as part of our thesis. |

 M51 Robert Lupton Department of Astrophysics M51, the “Whirlpool” galaxy in the constellation Canes Venatici, is about 30 million light years away from the Milky Way. The image shows two colliding galaxies, which have torn stars from their outer parts and spread them over much of the field of this image. The image is from the Sloan Digital Sky Survey (SDSS). The red, green, and blue color planes represent infra-red, red, and green filters. |

 Knowledge is Beautiful Elyse Graham '07 Department of English, Comparative Literature studies This image is the first from a series of 12. They depict some of history's great scientific minds with the seductive physical draw that their minds hold for us intellectually. It's a laugh, but it's also a recollection of Blaise Pascal's "Clarity of mind is clarity of passion." We practice science because we love it. So, too, do we practice art. The figures are given male heads and female bodies in part to appropriate the old Platonic notion that divides "Mother" Nature (wild, sensual, unpredictable) and "Father" Science (logic and linearity). Contemporary investigation, criticism, and mixing between different sciences and spheres (History of Science, astrobiology, and so on) is opening those borders to new fields of analysis. The imagery also interrogates the traditional male-centeredness of science, and looks to an opening world in which science is performed by, and for, all of humanity rather than a restricted category or sex. |

 Danish or Doughnut Joshua Podolak GS Department of Computer Science This series of images is a result of a project to automatically fill holes in polygonal meshes. While in simple cases it suffices to create a patch by triangulating the boundary of a hole, in cases where the topology of the final object is uncertain a more complex method is needed. In the figure shown, using our “Atomic Volumes” method, the outer half of the torus can be filled in two topologically different ways. The viewers can decide if they see a Danish or a doughnut. |

 G. dehiscens Laura K.O. Smith '05 Department of Civil and Environmental Engineering Globoraquadrina dehiscens is a planktic foraminifera, which means that it is a floating microfossil. Its average size is about the size of a grain of sand. G. dehiscens first appears in the fossil record at the very beginning of the Miocene (24 million years ago) and is used world wide as an indicator of the Miocene/Oligocene boundary. This sample was collected from the Gee Greensand at from Campbell’s beach in Otago, New Zealand, in order to date the Greensand. The Gee Greensand also contains many macrofossils including corals, shark’s teeth, echinoderms, and brachiopods. The fossils, grain size, and mineral content of the Gee Greensand, as well as proximity to other rock formations, suggest that the Gee Greensand was deposited during a low sedimentation period and in very shallow water. G. dehiscens, along the presence of G. labicrassata, and G. woodi woodi, narrowed the age of the sediment to the base of the Waitakian Stage, the New Zealand stage for the beginning of the Miocene. |

 Cricket Maria M. Ramos GS Department of Ecology and Evolutionary Biology We collected samples of insects in a Louisiana bayou to evaluate prey availability for Anolis lizards. After we measured their hardness the insects' bodies would often break apart, as in the case of this giant cricket. Its image was captured with the help of a regular scanner. |

 Fake Forest Henry S. Horn Department of Ecology and Evolutionary Biology This is a photograph of the screen of an IBM PC-AT, taken in the penultimate decade of the last Century of the previous Millennium. The trees realize a 6-times fractally iterated ‘turkey-track,’ with variations in the angle between the toes and in the shrinkage at each iteration. Code in BASICA was less than two pages, ... and most of that was housekeeping. As ‘educational’ software, this won a local IBM contest and got me a trip to Disneyland. Parameters like the branching angle, shrinkage, and number of iterations can be measured on real twigs and real trees. Constructing fake trees with real parameters led me to novel insights into the role that developmental ‘architecture’ plays in adapting trees to gradients of light to shade, dry to wet, canopy to understory, and field to forest. Horn, H. S. (2000) Twigs, trees, and the dynamics of carbon in the landscape, pp. 199-220 in J. H. Brown & G. B. West, eds., Scaling in Biology, Santa Fe Institute Studies in the Sciences of Complexity, Oxford University Press. |

 Colored Buckles Rebecca L. Peterson GS Department of Electrical Engineering This image shows the topography of a buckled thin silicon-germanium semiconductor film measured by Atomic Force Microscopy over a 25µm x 25µm area. Under the film is a layer of glass supported by a silicon wafer. When the sample is heated to high temperature (750C), the glass flows and the film, which is initially smooth and flat but under compressive strain, forms buckles with an amplitude of about 30nm to relieve its strain. The buckles occur along the <100> crystal directions (which run roughly diagonal in this image) due to the asymmetric mechanical properties of the silicon-germanium crystal. Here, the data have been colored to highlight the periodicity and beauty of the buckles. This work was done in the lab of Professor James C. Sturm and the PRISM micro/nano fabrication facility, and is in collaboration with Karl D. Hobart of the U.S. Naval Research Lab. |
