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
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.
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.
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.
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.
