Atom in a Box is an application that aids in visualizing the Hydrogenic atomic orbitals, a prime and otherwise unwieldy example of quantum mechanics. Unlike other tools in this category, this program raytraces through a three-dimensional cloud density that represents the wavefunction's probability density and presents its results in real-time (up to 48 frames per second on the latest hardware). The user interface is very interactive and provides a wide degree of flexibility. It contains all 140 eigenstates up to the n=7 energy level and the allowed spectral transitions between those eigenstates. It also allows a state more...

What's New

This is a terrific teaching and learning tool for intro quantum mechanics. It is a visual treat, and versatile tool that aids in the development of understanding and intuition about QM. The user can select quantum numbers, and see beautifully executed manipulatable animations of the probability density. Many other features are available. No teacher or student of intro QM should get through the hydrogen atom without spending some time with this.

wish I had had this when i was dooing my chemistry A-level...or actualy at any point when I was doing quantum mechanicy stuff... very cool
