This week Dr. Gerald Pollack returns as our guest. He is a Professor of Bioengineering at the University of Washington and an international leader in the field of water research. He received his Ph.D. from the University of Pennsylvania in 1968. Since then, his research interests have ranged broadly over the scientific spectrum, from cardiac dynamics and electrophysiology, to muscle contraction, cell biology, and more recently to the role of water in nature. Currently Dr. Pollack runs the Pollack Laboratory at the University of Washington, which focuses on uncovering some of nature’s most deeply held secrets. He is also the Editor-In-Chief of the scientific journal WATER, a multidisciplinary research journal that brings together water-oriented research from diverse disciplines. A fantastic voyage through water, revealing a hidden universe teeming with physical activity and providing answers so simple that any curious person can understand. Author, Gerald Pollack and colleagues at his University of Washington laboratory have discovered that water is NOT always H2O. When touching most surfaces, water transforms itself into so-called Exclusion Zone (EZ) water, whose formula is H3O2. EZ water differs in all respects from H2O. And, there is a lot of it, everywhere. The Fourth Phase of Water: Beyond Solid, Liquid, and Vapor documents this fundamental discovery and uses it to explain common everyday phenomena, which you have inevitably seen but not really understood. Professor Gerald Pollack writes in a clear, eloquent style. Whimsical illustrations and simple diagrams help get his points across in a reader-friendly manner perfectly suitable for non-experts.
