The Hidden Qualities of Water

Water is essential for life. It's also vital that we know about the quality of our water and how it is affected by its environment. Theodor Schwenk, the acclaimed author of Sensitive Chaos, developed the Drop Picture Method to analyse the quality of water. This collection of articles from the Institute of Flow Sciences that he founded provides detailed information on how the method works, how impartiality is assured and research into different parameters affecting the images. The book includes a study of a section of polluted river which shows self-purifying properties, and an evaluation of the issues surrounding our drinking water.
