I love looking at the intersections of art and science and the science of art. Psychology/sociology/anthropology could be construed as the study of human artforms and behaviors. Where as geometry/biology/physics can be seen as a more empirical art. The equation is the paint, where the answer is the solution. The solution being how viscous a medium is, or the way light hits certain elements.
As a graphic designer, science is essential to my image making. Just take a look at this Wikipedia page on Bézier Curves (http://en.wikipedia.org/wiki/B%C3%A9zier_curve). Granted I didn't read most of it, but I love the break down of how the curve functions and the calculations it takes to get there. I'm particularly enamored with this image:
There are also the use of pendulums to create spirograph like images, where the weight, angle and type of contraption being used determines the end piece. Which are then displayed as art.
