2014 spring – MAT 2680 Differential Equations – Reitz

A differential equation is an equation that relates a function to one or more of its derivatives. – The above rather boring description does little to convey just how fundamental, widespread, and amazingly effective differential equations are in describing the world around us. – Examples: Anything in motion. Also, many things that are not in motion. Also, many additional things to which the word “motion” does not really apply. – Further examples: spaceships in orbit, populations growing and shrinking, a cup of coffee slowly cooling, springs bouncing, financial markets rising and falling, electrical current flowing through a circuit, ocean waves, sound waves, light waves, vibrations in musical instruments and airplane wings and suspension bridges, – More examples: Pretty much everything. Topics include methods of solving ordinary differential equations and applications to various problems.

Prof Cheng’s Fall 2013 History of Photography

ARTH1100-D400. This course surveys the history of photography from its beginnings in the early nineteenth century to the present. We will examine the use of photography for aesthetic, documentary, and “scientific” purposes, stylistic shifts in photography related to aesthetic concerns, and varying interpretations of subject matter based on social and cultural concerns at specific moments in history. We will also consider the relationship between photography and the visual arts in general, which culminates with the primacy of photography as a medium by the late twentieth century.

MAT2680 Differential Equations, FA2013

A basic introduction to ordinary (not partial) differential equations. While systems are discussed, the focus is on the solution and analysis of single equations and the physical processes from which they may have originated. While many of the most common solution techniques are covered, including numerical, the emphasis is on qualitative analysis and the use of technology.
