A Computational Analysis of the Fermi, Pasta, Ulam Paradox

This paper presents a computational study of the Fermi, Pasta, Ulam (FPU) paradox as it is applied to a system of nonlinear springs and thirty-two masses. The chain of springs and masses experiences motion only in one direction without the forces of friction or internal heating present to reduce the energy of the system. The program, written in Python, uses the Runge-Kutta method and Newtons second law for its calculations of motion.

Energy of a Two-Gas System

This paper presents a computational program designed to simulate a two-gas system in Visual Python. Similar to the well-known "Particles in a Box", this simulation aims to illustrate the energies of two initially separated gases of different temperatures as they mix together and proceed toward equilibrium.

The Zeeman Catastrophe Machine

Catastrophe theory states that for certain non-linear systems, small changes in the parameters may cause dramatic changes in the equilibrium. The problem is how to set the parameters such that one can examine the interesting behavior of the hypothetical situation. This paper examines the aspects of the chaotic Zeeman Catastrophe Machine, invented by Christopher Zeeman in 1969.

Thermodynamic Properties of Engine Cycles

The objective of this project was to create a model for three different types of engine cycles: Carnot Cycle, Otto Cycle, and Brayton Cycle. These models will simulate the different steps of each process and calculate the energy and work done. The models were all initially computed using hydrogen as a fuel source. Real data was then obtained that allowed the models to be adjusted to match more realistic situations.

H. A. Lorentz as the Grandfather of Quantum Physics

The first Solvay Conference in the fall of 1911 set a precedent for how leading physicists collaborate in order to solve difficult problems such as blackbody radiation and the photoelectric effect. By the end of the fifth Solvay Conference in 1927, the foundation had been laid for the theory of Quantum Mechanics. Besides featuring many prominent scientists in the field of quantum physics such as Einstein and Bohr, the first five Solvay Conferences had one very important characteristic that they all shared: they were chaired by Hendrik Lorentz.

The Idea of Our University

To found the famous Core curriculum of the University of Dallas, as an education "best for the individual," Donald and Louise Cowan looked to John Henry Newman's The Idea of a University. He unapologetically promotes the Western classics -- precisely because so few know our own culture well enough to appreciate the depth of any other.

To Russia with UD: Faculty to Lead UD's First Tour of Russia

This summer, the University of Dallas invites students, alumni, faculty and staff to join its first-ever tour abroad of Russia, led by Professor of Physics Richard Olenick and Affiliate Instructor of Spanish, French and Italian Irina Rodriguez. From June 8 to June 16, 2020, Olenick and Rodriguez will guide participants through the cities of Moscow and St. Petersburg, taking them on a cultural and literary tour of the "Russian soul."

Cowan-Blakley Memorial Library Showcases Rare Books Room

No longer relegated to the damp lower level, the Cowan-Blakley Memorial Library's Rare Books Room has for the past two years occupied a prime spot on the second floor, where there used to be study carrels. The room, made of glass walls, is normally locked and only opened by appointment, but on Sept. 26, the library hosted an open house for faculty and staff to come and examine these treasures.
