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. 


2018 Galbraith Lecture Explores 'Dante and Liturgical Time'

As we age, most of us ask ourselves, where has the time gone? Borrowing text from UD's Core curriculum, this spring semester's Galbraith Lecture will explore the difference between our own perception of time, and how the philosopher-poet Dante Alighieri viewed mankind's immortal clock, steeped in Scripture and in life.

UD Presents: 'Dwelling: Paintings by Peter Ligon and Layla Luna'

The Beatrice M. Haggerty Gallery is pleased to announce an upcoming exhibition featuring two Dallas/Fort Worth area artists, Peter Ligon and Layla Luna, who articulate the architectural styling of dwelling spaces in their paintings. Both artists will give presentations at an opening reception on Friday, March 23, at 5:30 p.m. in the Haggar Art History Auditorium located in the Haggerty Art Village on the University of Dallas’ Irving campus.

Politics Major Empowers Youth, Shares Story Through Theater

Although she herself is not able to vote, Liz Magallanes, BA '18, works to make voting possible for other people. She first got involved with the organization Mi Familia Vota in 2014 and has been contributing to their endeavors ever since, including working with high school students in Dallas ISD. Additionally, she recently had a role in the play "Deferred Action."
