The EJS Barrier Scattering model shows a quantum mechanical experiment in which an incident wave (particle) traveling from the left is transmitted and reflected from a potential step at x=0. Although the analytic solution to this standard problem is well known, its visualization shows how the incident and reflected waves form an interference pattern and how the incident wave penetrates the classically forbidden region when its energy is less than the barrier height height V0

" This seminar examines the history and legacy of the Cold War on American science. It explores scientist's new political roles after World War II, ranging from elite policy makers in the nuclear age to victims of domestic anti Communism. It also examines the changing institutions in which the physical sciences and social sciences were conducted during the postwar decades, investigating possible epistemic effects on forms of knowledge. The subject closes by considering the place of science in the post-Cold War era."

The free particle energy eigenstates model shows the time evolution of a superposition of free particle energy eigenstates. A table shows the energy, momentum, and amplitude of each eigenstate.

The EJS Multiple Slit Diffraction model allows the user to simulate Fraunhofer diffraction through single or multiple slits. The user can modify the number of slits, the slit width, the slit separation and the wavelength of the incident light. The scale of the diffraction pattern can also be changed and a plot of the light intensity can be toggled on and off with a checkbox.

The material universe is a gigantic machine, a computer, whose hardware exists in the form of non-spatial feelings or states of consciousness. The workings of this non-spatial universal computer are described in my NSTP (Non – Spatial Thinking Process) theory. The NSTP theory is based on 7 self-evident propositions and 3 conjectures. It thus provides a concrete mathematical basis for metaphysical idealism and brings out a non-spatial computational description of the material universe. The NSTP theory self-evidently states matter as non-spatial and the new revolutionary (universal) mechanics as non-spatial (computational). It portrays non-spatial (computational universal) mechanics and further proposes the 21st century revolution in science and physics.

The EJS QM Eigenstate Superposition Demo model displays the time dependence of a variety of superpositions of energy eigenfunctions for the infinite square well and harmonic oscillator potentials. One of the eleven pre-set superpositions can be selected via a drop-down menu with the resulting wave function shown in phase-as-color representation. A table of the expansion coefficients is shown and can be edited. The width of the infinite square well potential can be changed via a slider.

This is an outline for how one could incorporate quantum mechanics into atomic structure. Students really seem to get hooked on it and it makes atomic structure way more interesting to teach.

The first free comprehensive textbook on quantum (and classical) field theory. The approach is pragmatic, rather than traditional or artistic: It includes practical techniques, such as the 1/N expansion (color ordering) and spacecone (spinor helicity), and diverse topics, such as supersymmetry and general relativity, as well as introductions to supergravity and strings. The PDF version can be more convenient than paper books, with Web links and a clickable outline (contents) window.

Quantum Information Processing aims at harnessing quantum physics to conceive and build devices that could dramatically exceed the capabilities of today's "classical" computation and communication systems. In this course, we will introduce the basic concepts of this rapidly developing field.

Introduction to Quantum Physics concepts with an activity demonstrating Heisenberg's Uncertainty Principle, wave/particle duality, Planck's Constant, de Broglie wavelength, and how Newton's Laws go right out the window on a quantum level.

The Spins package is a self-contained file for the teaching of measurement and time evolution of spin-1/2 systems in quantum mechanics. The file contains ready-to-run OSP programs and a set of curricular materials. The material focuses on single and multiple measurements of different ensembles of identically prepared spin-1/2 particles. The OSP Collection provides curriculum resources that engage students in physics, computation, and computer modeling. Computational physics and computer modeling provide students with new ways to understand, describe, explain, and predict physical phenomena.

This online video gallery is from the Museum's Seminars on Science, a series of distance-learning courses designed to help educators meet the new national science standards. Reflections on Einstein, part of the Frontiers in Physical Science seminar, is available in broadband and modem formats and with a printable PDF transcript. The video shows excerpts of a panel of seven scientists reflecting on Einstein's influence.
