Fermi-Pasta-Ulam Model v.1.0
The Fermi-Pasta-Ulam (FPU) problem is named after the numerical experiments first performed by Enrico Fermi, John Pasta, and Stanislaw Ulam in the summer of 1953 on the Los Alamos MANIAC computer, one of the first electronic computers.

Special Functions Model v.1.0
Study math functions with this tool. EJS Special Functions Model shows how to access special functions in the OSP numerics package.
Ceiling Bounce Model v.1.0
Study gravitational acceleration using this simulation. Ceiling Bounce Model shows a ball launched by a spring-gun in a building with a very high ceiling and a graph of the ball's position or velocity as a function of time.
Classical Helium Model v.1.0
Classical Helium Model is a three-body problem simulation to help you with your studies. Classical Helium Model is an example of a three-body problem that is similar to the gravitational three-body problem of a heavy sun and two light planets.
Molecular Dynamics Model v.1.0
Study molecular dynamics with this tool. Molecular Dynamics model is constructed using the Lennard-Jones potential truncated at a distance of 3 molecular diameters. The motion of the molecules is governed by Newton's laws,
Tabletop Projectile Model v.1.0
The Tabletop Projectile model simulates the frictionless motion of a ball shot from a tabletop by a spring-gun The initial velocity and the table height can be set and multiple shots can be compared. A separate window shows a position data table.
Electric Generator Model v.1.0
Study electromagnetic induction with this simulation. Electric Generator Model shows a simple electric generator made from a conducting loop rotating in a uniform magnetic field and connected to an ammeter.
Fourier Sine Series Model v.1.0
Study the sine series expansion coefficients with this tool. The Fourier sine series model displays the sine series expansion coefficients of an arbitrary function on the interval.
Harmonics and Fourier Series Model v.1.0
Analyze harmonics sum fast and easy. Harmonics and Fourier Series model displays the sum of harmonics via a Fourier series to yield a new wave. The amplitude of each harmonic as well as the phase of that harmonic can be changed via sliders.
Newtons Law of Cooling v.Model
Study Newton's Law of Cooling with the help of this simulation. Newton's Law of Cooling model computes the temperature of an object of mass M as it is heated by a flame and cooled by the surrounding medium.
Lennard-Jones 2D Metropolis Program v.1.0
Simulate Lennard-Jones particles with this application. The STP LJ2DMetropolis software is a Monte Carlo simulation of Lennard-Jones particles in two dimensions in contact with a heat bath.
