Part of the larger Imagine the Universe educational site, the Electromagnetic Spectrum site is another great resource from NASA. The site gives clear and easy-to-understand explanations, while providing keywords throughout the page that are linked to a dictionary of terms for easy access to further information. Students will enjoy the colorful illustrations accompanying the text, which vertically...

The Russian Academy of Sciences' Institute for Physical Problems (IPP) explores aspects of low-dimensional magnets, non-linear dynamics of magnetically ordered crystals, and magnetic resonance. Researchers can learn how the ESR spectrometers utilized by the group permit flexibility in their experiments. Students and educators can discover the importance of quasi 1D magnet with ladder structure...

It is commonly thought that the behavior of physical systems is controlled by deterministic laws, yet physical processes appear to be unpredictable. This Topic in Depth discusses how the concepts of self-regulating systems, dynamic equilibrium, and chaos theory help to rectify this conundrum. The first website ({1-- http://dbhs.wvusd.k12.ca.us/Equilibrium/Dynamic-Equilibrium.html}), developed by...
