"Challenges and solutions".
Title from resource description page (viewed August 14, 2018).
This program traces the story of how humans have always practiced chemistry; how, over time, it developed from a practical discipline into a science. Today, we keep up the chemists' tradition to refine and purify substances. A current, real-life application of the "art of the meticulous" is the refining and purification of pure silicon from a common material—silica sand—for advanced electronics, such as cell phones and solar cells.
