Interactive Periodic Table

Teaching chemistry, physics, or a math class doing problems on exponential decay? Check out this spectacular interactive periodic table created by Michael Dayah. Among the awesome features:

1. pop-up windows showing Wikipedia entry for each element
2. temperature slider showing physical state of all elements at a given temperature
3. half-lives for every element (data for exponential decay problems in pre-calc!)
4. option to display every element's abundance in the universal, solar system, meteors, crust, oceans, and humans (uranium's abundance in humans: 1.0×10^-7%!)
5. electron orbitals with 3-D visualization
6. a useful About page telling students, among other things, how to cite the table in MLA and APA.
