Earth Orbit Model v.1.0
Copernican theory illustration. Earth Orbit model illustrates the Copernican theory of Earth's orbit around the sun. The top window shows a view from outside the celestial sphere.
Random Walk 2D Model v.1.0
Analyze a 2D random walk with this application. EJS Random Walk 2D Model simulates a 2-D random walk. You can change the number of walkers and probability of going a given direction.
Radioactive Decay Model v.1.0
Radioactive sample decay simulation. Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time.
Standing Waves on a String Model v.1.0
Simulate a standing wave on a string with this application. Standing Waves on a String model displays the motion of a standing wave on a string. The standing wave can be augmented by adding the zero line and the maximum displacement of the string.
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.
Magnetic Bar Field Model v.1.0
Magnetic field simulation to help you with your studies. Magnetic Bar Field Model shows the field of a bar magnet and has a movable compass that reports the magnetic field values.
Waveguide Model v.1.0
Analyze waveguide with this tool. Waveguide model displays the motion of a traveling wave forced to move between two walls in a waveguide. The two walls are located at y = 0 and a, so that its normal modes are u(t,
Ising 1D Program v.1.0
Ising model in equilibrium simulation. The STP 1DIsing software is a Monte Carlo simulation of a one-dimensional Ising model in equilibrium with a heat bath at temperature T using the Metropolis algorithm.
