Shoemaker by Levy: The Man Who Made an Impact

Gene Shoemaker was truly a giant of 20th Century Science. Involved in the development of (and frustrated by) the vestigal scientific programs attached to the oh-so-political US moon program, Gene Shoemaker was a frequently-acknoledged genius. Perhaps most famous, along with his wife Carolyn and (this book's author) David Levy, for his work discovering the comet chain (Shoemaker-Levy 9) which impacted Jupiter in July 1994, Shoemaker's true legacy lay in his role as a key proponent of the theory, now widely-accepted, that most of the craters we observe in the solar system were caused by meteor or comet impacts instead of being cause by volcanism, and that this process has been at work on the Earth for millenia as well, as can be seen at places like Meteor Crater in Arizona.Levy is always a treat to read, with an enthusiastic and easygoing style which keeps the subject accessible and the language casual. He moves the narrative effectively, and frequently refers back to earlier portions of the book to jog the reader's memory regarding various details. The book follows a more-or-less chronological course in relating Shoemaker's life, although it does follow concurrent threads in seperate chapters, so it may confuse less-attentive readers from time to time as Levy covers Shoemaker's gological work during a particular decade in one chapter, and in the next might jump back to the end of the previous decade while describing his astronomical work. The book's only real flaw is in it's extreme reverence for Shoemaker and the resultant unwillingness to dig for "dirt" in the process of profiling this colorful and contentious man, understandable considering how close Levy was to Shoemaker, and how close he remains to Shoemaker's wife Carolyn. While the general impression is that there was little actual dirt to be found, Levy glosses over some conflicts in Shoemaker's life, especially the significant personal break with his one-time student and co-collaborator Eleanor Helin, whose near-Earth object research has been truly influential as well. Additonally, passing but tantalizing mention is made in places of his (apparently) less-than-perfect relationship with his children when they were young.All in all, these lapses are insignificant (worth a point off a pefect score, though), especially since it will most likely be many years before we are treated to any more thorough and (perhaps) less-biased biography by any other writer. Heartily recommended to anyone who likes a good biography or who has an interest in geology or the search for near-earth objects.

This is an excellent (and probably the only) bio of Eugene Shoemaker, who nearly singlehandedly pioneered impact geology, and by doing so helped make modern, secular catastrophism palatable to scientists. On page 55 Levy quotes Stephen Gould (from "The Panda's Thumb") regarding the origin of gradualism as "a common cultural bias"; discusses Cuvier's near miss regarding the source of catastrophes attested throughout the fossil record (pp 51-52); and most nobly and notably, recounted with pretty good accuracy the central thesis of Velikovsky's Worlds in Collision without resorting to the childish distortions and namecalling found in most books which mention Velikovsky at all. This factual, non-inflammatory mention of Velikovsky and what may be the most controversial non-political work of the 20th century reveals Levy as a man of reason, courage, and character.This biography is highly recommended.Also recommended:-:- "Dark Matter" by Thomas Van Flandern-:- "The Deep Hot Biosphere" by Thomas Gold-:- "Voices of the Rocks" by Robert Schoch et al-:- "Night Comes to the Cretaceous" by James Lawrence Powell-:- "Rain of Iron and Ice" by John S.

A truly delightful book about the premiere scientist. The book takes you from the early days when Gene was a kid collecting rocks in a jar, to his prominent role with the Apollo project to the seach for asteroids. Levy writes in such a way that you almost feel that you were friends with the man. Looking over his shoulder as he takes college kids on field trips to Meteor Crater and in the control room for the Voyager missions. I never knew Gene was involved in so many aspects of astronomy. Anyone who relishes science biographies should not miss this one.

Soon after pieces of Comet Shoemaker-Levy 9 began impacting Jupiter, I checked Jupiter with my 3.5" telescope and was delighted to see impact spots. Just a day before astronomers were fearful that there would be no visible trace of the impact and of the reaction of the media to the "non-event".Somehow I didn't take time to reflect on the "rightness" that the comet was discovered by the scientist most responsible for our current understanding of past and future impacts on the Earth. I guess it just seemed obvious that Shoemaker was the one to find the comet. (Actually, his wife Carolyn was the first to see it on film Gene and David Levy exposed.)The day after his death I heard of the idea to include some of his ashes on the Lunar Prospector satellite that was soon to launch, orbit, and eventually crash on the moon. While I instantly recognized what a wonderful idea that was, my memory was fuzzy on his long contribution to lunar exploration.Levy's biography is a wonderful summary of the Shoemakers' life and contributions to astrogeology. Shoemaker will be remembered as one of the most important scientists of the 20th century. Shoemaker's enthusiasm for geology was a key to his success and Levy concentrates on that, leaving the technical aspects to the bibliography. The result is a book anyone can read and all can learn from.Five stars, several asteroids, and dozens of comets!
