The three-dimensional real and reciprocal lattices can be rotated and magnified. Also, the real and reciprocal space lattice matrices are displayed. Gibbs Phase Rule for One- and Two-Component Systems http://www.merlot.org/merlot/viewMaterial.htm?id=645086 Animation of the Gibbs Phase Rule for one component and two component systems. Various regions in the phase diagrams can be selected to show the relationship between the number of components, phases and degrees of freedom. Interactive Wolfram Demos for Physics and Physical Chemistry http://www.merlot.org/merlot/viewMaterial.htm?id=429364 Interactive Wolfram demonstrations of concepts in physical chemistry Point Groups and Bravais Lattices http://www.merlot.org/merlot/viewMaterial.htm?id=632889 The 32 crystallographic point groups are rendered by the Rayshade 3-D ray tracing program. Animated GIF movies and high resolution JPEG images may be downloaded and used to illustrate symmetries of the crystallographic point groups. The following article provides detailed information regarding the use of the three-dimensional point group renderings.Teaching crystallographic and magnetic point group symmetry using three-dimensional rendered visualizations Superposition of Waveforms http://www.merlot.org/merlot/viewMaterial.htm?id=82704 The wavefunction for a particle with an ill-defined location can be regarded as the sum (superposition) of several wavefunctions of different wavelength that interfere constructively in one place but destructively elsewhere. As more waves are used in the superposition, the location becomes more precise at the expense of uncertainty in the particle's momentum. The Fermi-Dirac Distribution http://www.merlot.org/merlot/viewMaterial.htm?id=82700 This is an applet that explore the form of the Fermi-Dirac distribution for different values of chemical potential.
