A review of the book, The Age of the Earth. Presents the standard interpretation of radioisotope data. Published in Origins v. 19, n. 2.

Dates calculated from radiocarbon and amino acid racemization show conflict. Analysis of the discrepancies and use of a radiocarbon conversion published earlier, some inferences are drawn regarding the cooling of the earth after the biblical flood. Published in Origins v. 18, n. 2.

Assumptions may eventually become so widely accepted they are no longer recognized as assumptions but take the status of truth. Two examples that relate to origins are assumptions of abiogeneis and long ages. These points should not be assumed but tested if one wants to discover truth. Published in Origins v. 18, n. 1.

This is an attempt to develop a methedology for converting carbon-14 ages into real time in a biblical context that fixes the date of the global flood at about 5,000 years ago. A table is provided of sample converted ages. Published in Origins v. 17, n. 2.

A review of the book, Absolute Age Determination. An authoritative description is provided of the methods of age-dating used to estimate the age of the earth. Published in Origins v. 17, n. 2.

The approach outlined in this paper suggests that the radiometric age assigned to the inorganic minerals associated with a fossil is more a reflection of the characteristics of the source of this inorganic material than an indication of the age of the fossil. Published in Origins v. 17, n. 2.

A review of the book, Principles of Isotope Geology. An authoritative description of radioisotope dating and use of stable isotope ratios. Published in Origins v. 16, n. 1.

The available data on C-14 age profiles indicate that the characteristic relationship is nonlinear in a direction which suggests that the C-14/C-12 ratio was less in the past than it is now. Published in Origins v. 15, n. 1.

This review examines Robert Gentry’s efforts to defend his model of creation built on the study or radiohaloes. Published in Origins v. 15, n. 1.

Some recent radiocarbon dates derived from sources assumed to be geologically very old give dates in the 40,000-year range. These relatively young dates may reflect the concentration of Carbon-14 in the antediluvian atmosphere. Published in Origins v. 15, n. 1.

A review of the book, The Geology of the Flood. The author advocates an age for the earth that is much longer than the biblical chronology and much shorter than the naturalistic chronology, which will make the book's position unsatisfactory to most readers. Published in Origins v. 14, n. 2.

A review of the book, Radiocarbon Dating: An Archaeological Perspective. Published in Origins v. 14, n. 1.

The geochronological time scale of thousands of millions of years is based mainly on radiometric dating. On the other hand, some other time-dependent processes change at rates which challenge generally accepted geochronology. Published in Origins v. 13, n. 2.

A collection of short commentaries on scientific articles published in 1983, covering topics such as the history of Darwinism, integrity in science, evolution and thermodynamics, North American geology, Quaternary dating methods, origin of life, and the half-life of Technetium-99.

A collection of short commentaries on scientifc papers published in 1983-1985, covering topics such as amino acid dating, problems in evolutionary theory, God and the New Physics, Scientists Confront Creationism, transgenic mammals, philosophy of science, and In the Minds of Men. Published in Origins v. 12, n. 2.

Most amino acids exist in two forms, commonly called "left" and "right." Living organisms use only "left" amino acids, but after death, the "left" amino acids begin changing to "right" forms, until there is an equal number of both. This suggests the possibility of using the amount of change as a measure of time, leading to the development of amino-acid dating. This dating of method does not confirm the results of other methods of dating. Published in Origins v. 12, n. 1.

The chronological figures in the Septuagint version of Genesis 5 and 11 are different in different manuscripts, and appear to have been altered. This indicates the superiority of the Masoretic text for these data. Published in Origins v. 12, n. 1.

Radioisotope ages are calculated from ratios of certain atoms. The isotopic ratios can be precisely measured, but the calculation of age from that ratio involves assumptions that may vary depending on the philosophical orientation of the investigator. Published in Origins v. 10, n. 2.

A review of the book, Christianity and the Age of the Earth. The book presents a biased viewpoint against recent creation, but does point out some serious challenges that confront recent creationists. Published in Origins v 10, n. 1.

The picture that emerges from all the data that relate to cosmic chronology appears to be one of dynamic physical processes operating over extended periods of time, during the last 4.5 billion years of which discrete entities of the Solar System have been in existence. This suggests the word "earth" in Genesis 1 may refer to the land surface of the planet, and not to the planet itself. Published in Origins v. 8, n. 1.
