This is a definitive, masterly history and synthesis of all that has been said (by theologians and scientists) and is known (to science) about the question, How old is the Earth? It explains in a simple and straightforward way the evidence and logic that have led scientists to conclude that the Earth and the other parts of the Solar System are not several thousand years old, as some today would have it, but four and one-half billion years old. It is a fascinating story, but not so simple as single measurement. Our universe is a large, old, and complicated place. Earth and other bodies have endured a long and sometimes violent history, the events of which have frequently obscured the record that we seek to decipher. Although in detail the journey into Earth's past requires considerable scientific skill, knowledge, and imagination, the story is not so complicated that it cannot be explained to someone who wants to know and understand the basic evidence. This book, then, has been written for people with some modest background in science, but at a level that will allow the material to be useful and accessible to those without a deep knowledge of geology or physics or mathematics.

How old is Earth? How old are the planets, the Moon, meteorites, stars, and the Universe itself? How do scientists know these things? If you’ve ever asked yourself some or all of these questions, then this book is for you. Planet Earth and the other bodies of the Solar System are 4.5 billion years old. They reside in a galaxy (the Milky Way Galaxy) that is 12-14 billion years old, and are part of a universe that is 13-15 billion years old. G. Brent Dalrymple, a geologist and widely recognized expert on the age of Earth, reviews the evidence that has led scientists to these conclusions and describes the methods by which this evidence has been gathered. The book is written in a highly accessible style, free of mathematics and complex graphs, and is intended for non-scientists who have an interest in the subject. People with scientific backgrounds who wish to have a thorough summary of the subject will also find the book useful.

Brent Dalrymple was born on March 7, 1937 in Baton Rouge, Louisiana, United States. He was the son of Jerry Richard and Dorothy (Benedict) Dalrymple.
Dalrymple attended Occidental College, in his home state of California, where he earned a Bachelor of Arts degree in geology in 1959. He then moved to the University of California, Berkeley, to do his graduate work. He earned his Doctor of Philosophy degree in geology in 1963.
In 1993 he received an honorary Doctor of Science degree from his undergraduate alma mater, Occidental College.
Dalrymple's interest in radiometric dating led to the publication of Potassium-Argon Dating, a guide to understanding the principles and techniques involved, which he co-authored with Marvin A. Lanphere in 1969. The book began as an abbreviated pamphlet, but was later expanded into a book by popular request. As the authors note in their preface, the book is not meant to be “a scholarly or comprehensive review” of the topic, but ts instead intended to answer “practical questions of what the method can and cannot do.” Dalrymple began his career as a research geologist with the U.S. Geological Survey (USGS) in Menlo Park, California, in the Branch of Theoretical Geophysics. He remained there until the early 1970s, when he moved to the Branch of Isotope Geology. Between 1981 and 1984, he was an assistant chief geologist for the Western Region of the USGS, during that time he was the principal contact within the USGS for the state geologists of the western states. Since 1984 he has served as a research geologist for the USGS.
During 5 years from 1989 he was a professor of finance University Texas at Pan Am. In 1994 he became a director of Financial Awareness Center.
Throughout his career Dalrymple has been involved in developing new methodology and instrumentation for determining the ages of rocks and minerals.
In addition to his primary research at the U.S. Geological Survey, Dalrymple has served in various roles at Stanford University, including visiting professor, lecturer, research associate, and consulting professor in the school of earth sciences. His affiliation with Stanford was intermittent during the 1970s and 1980s, but has been continuous since 1990.
He served on the Council of Scientific Society Presidents between 1990 and 1992.
Dalrymple left the U.S. Geological Survey in 1994.
Now he is a dean and professor at Oregon State University. He is also an instructor in celestial navigation.
He is currently researching lunar basin history.

Dalrymple is a member of Geological Society of America and American Academy of Arts and Sciences.
In addition to his role as the president of the American Geophysical Union—a society thirty thousand strong—Dalrymple serves on the board of governors of the American Institute of Physics, and was elected to the executive committee of that institute in 1993.
He was also a member of AAAS, American Geophysics Union and it's president in 1990-1992.
He is in the board of governors of American Institute of Physics from 1991.
