Measurement, and Temperature

Metric System The SI system with a short history of measurement

Temperature Temperature measurement with a short historical background

Absolute Zero This is a program from NOVA (split into 10 chapters). The program presents a history of temperature measurement up to the modern methods of trying to reach absolute zero. This is a link to the NOVA website.

The Elements and the Periodic Table

Element Symbols A historical approach to modern element symbols

Forging the Elements How were the elements formed? This is a segement from the NOVA program Origins: Back to the Beginning. Watch the entire program (split into 6 chapters) or just select the Forging the Elements chapter. This is a link to the NOVA website.

The Periodic Table This is a link to the Web Elements Periodic Table by Mark Winter, Dept. of Chemistry, University of Sheffield. Probably the best periodic table on the Internet, it provides a wealth of information about the elements. This is the place to look for information about the chemical elements.
