Water: So Common, So Mysterious

by Dr. Richard Zare of Stanford University

In The Rime of the Ancient Mariner, the great English poet Samuel Taylor Coleridge wrote “Water, water, every where, Nor any drop to drink.”

Indeed, water covers about four-fifths the surface of the Earth, and human life depends on potable water. Water is so abundant, its behavior so familiar, its appearance so commonplace, that we are tricked into thinking that there is nothing new to be learned about this substance. We may, however, be in for a surprise...

Unquestionably, water is a weird liquid in which its solid form, ice, floats on liquid water at room temperature. If water were not densest at 4 degrees C, ice in ponds and rivers would freeze from the bottom up and kill all aquatic inhabitants; if water did not absorb heat so well, water on the Earth would have boiled away long ago; and so forth. Imagine our surprise to find that tiny water droplets can be highly reactive and behave different from that of bulk water. This talk will emphasize the odd world of water microdroplet chemistry, which is threatening to have practical applications.

Dr. Zare is the Marguerite Blake Wilbur Professor in Natural Science at Stanford University with an appointment in the Department of Chemistry & a courtesy appointment in the Department of Physics. He is a graduate of Harvard, where he received his B.A. in chemistry and physics in 1961 and his Ph.D. in chemical physics in 1964. In 1977 he moved to Stanford. He is renowned for his research in the area of lasers applied to chemical reactions and to chemical analysis. He is the recipient of many awards and has authored and co-authored 1000+ publications.

This seminar is hosted by Tribe Chemistry with support from the Jean Dreyfus Lectureship for Undergraduate Institutions.
