On attending a conference on the Jovian satellites at UCLA, I heard Lou Lanze rotti vigorously present the exciting data on the sputtering of water ice by Me V protons taken with W. L. Brown at AT&T Bell Labs. In his inimitable way he made clear that this new electronic sputtering process was very poorly under stood and was very important for surface properties of sattelites. I was immedia tely hooked, and have been working ever since with Lanzerotti, Brown, my col league at Virginia, John Boring, and Bo Sundqvist at Uppsala on understanding the ejection of material from surfaces and applying laboratory results to intere sting planetary problems. In the course of writing this book I also had the benefit of spending a semester with the Planetary Geosciences group in Hawaii, thanks to Tom McCord, a period of time with Doug Nash at JPL, and a period ot time with the group at Catania. The book was started with the encouragement of Lou Lanzerotti. The writing has gone slowly as the field has been changing rapidly. Even now I feel it is incom plete, as the interesting Halley dust data have just recently been interpreted in detail, Voyager has recently visited Neptune, and the data on Pluto are rapidly improving. However, most of the principles for plasma ion alteration of surfaces and gases have been established allowing, I hope, a coherent and useful frame work for incorporating both new laboratory and planetary data."

Coinciding with the four-hundredth anniversary of the birth of the Baptist movement, this book explores and assesses the cultural sources of Baptist beliefs and practices. Although the movement has been embraced, enriched, and revised by numerous cultural heritages, the Baptist movement has focused on a small group of Anglo exiles in Amersterdam in constructing its history and identity. Robert E. Johnson seeks to recapture the varied cultural and theological sources of Baptist tradition and to give voice to the diverse global elements of the movement that have previously been excluded or marginalized. With an international communion of over 110 million persons in more than 225,000 congregations, Baptists constitute the world s largest aggregate of evangelical Protestants. This work offers insight into the diversity, breadth, and complexity of the cultural influences that continue to shape Baptist identity today.

Why should Job, a God-fearing man, lose his family, his friends, his wealth and his health in one fell swoop? Will he maintain his obedience to the Lord when his pleas for understanding are not heard? Can there be any positive resolution to this tragic situation?

The African American legacy in biblical history is very rich indeed. In this impeccably researched and easily readable work, Dr. Robert E. Johnson Sr., gives African American history students and casual readers alike even more reason to be proud of our heritage in religion, in the church, and in history.
