Plasma Plume: Towards Freedom, Prajwal Niraula, Saint Peter's University
I work with plasma as a part of my research work. When I look at the plasma plume that escapes from the end of the glass tube, it evokes a sense of freedom. I see a strong parallelism between the liberation I feel when learning the rules of the universe I live in, and the freedom argon gets in coming out of a pressurized gas cylinder as resplendent plasma, and finally dying out in the air as a minority. Thus, I believe my photograph serves as an emblem for connecting different world, as it signifies bridging the gap of the experiments with the experience of the experimenter.
Into the Heart of a Supercell, Glenn A. Marsch, Grove City College
Literally showing Sturm und Drang, this photo shows the spectacular violence of a supercell thunderstorm. Over its lifetime, a supercell thunderstorm generates more energy (> 20 kilotons TNT equivalent) than that liberated by an atomic bomb. On a basic level, the lightning may demonstrate the triboelectric effect, or electrical charging by friction, as the violent convection cells in a thunderhead rub electrons off ice crystals and water droplets in the cloud. This charge builds up, and if the electric field surpasses the dielectric strength of air (~ 3x106 V/m), an explosive discharge occurs across regions of high potential difference and the molecules of air break down and ionize.
Organized Chaos, Sarah Rozman, University of Central Florida
In this painting I attempted to create a sense of chaos, and I incorporated birds because of their natural built-in sonar systems. Birds almost never collide with each other, despite their quick speeds and sudden changes in movement. There is a theory that relates to the process of synesthesia, a human condition that blurs senses so that a person can hear colors, taste a smell, or visually see music. According to this theory, birds in flight sense one another’s closeness (by eyesight) and read the signals as a form of touch. Birds read their personal “sonar” and thus, avoid colliding with one another.
