A number of factors could affect the relation of C-14 concentration to real time. The author discusses the effects on C-14 dates of cosmic ray intensity, geomagnetic field strength, water vapor concentration, and dilution by the biosphere carbon. Published in Origins v. 6, n. 1.

A review of the book, Principles of Isotope Geology. This is an authoritative textbook on radioisotope dating that provides useful background information, regardless of philosophical persuasion. Published in Origins v. 6, n. 1.

The effects of glaciers are well-dccumented in modern and Pleistocene sediments. Some Precambrian and Paleozoic sediments show some features similar to those of modern glaciation, but there is some controversy over whether the features are the result of glaciers, submarine landslides, lahars, turbidity currents, etc. Published in Origins v. 6, n. 1.

The account of the flood as given in Genesis is brief, and many different interpretations have been given to the events described therin. Three expressions used in that narrative will be analyzed below in an attempt to show their original meaning. Published in Origins v. 5, n. 2.

Review of the article, Biologists, Help! An appeal by a secular scholar for evolutionists to explain why so many fundamental suppositions of evolutionary theory are so poorly supported by the data. Published in Origins v. 5, n. 2.

A review of the book, Puncuated Equilibria: The Tempo and Mode of Evolution Reconsidered. The new theory of punctuated equilibria acknowledges the gaps in the fossil record used by creationists as evidence against evolution, and explains them as due to the nature of the speciation process. However, the new theory applies only to gaps between species, and does not help with the problem of gaps between higher taxa. Published in Origins v. 5, n. 1.

Radiometric dates are subject to uncertainties due to the assumptions inherent in the method and to the effects of non-natural changes in the earth's crust on the third day of creation and during the biblical Flood. Published in Origins v. 4, n. 2.

Tektites are formed from molten target rocks by an extraterrestrial impact. Australian tektites dated at about 700,000 years are found resting on soil dating less than 10,000 years old. This discrepancy is unresolved at present, and provides an opportunity for further research that could be very significant for the question of radiometric dating. Published in Origins v. 4, n. 2.

Similarities in structure, or homologies, are what one would expect if all of life had been designed by a single Creator. Homologies are not evidence for evolution. Published in Origins v. 3, n. 2.

Several scientists have acknowledged that the evidence for evolution is deficient, and new approaches and information are needed. Published in Origins v. 3, n. 1.

The Glen Rose region of the Paluxy River does not provide good evidence for the past existence of giant men, nor does it provide evidence for the coexistence of such men and the giant dinosaurs. Published in Origins v. 2, n. 2.

There are two conflicting schools of interpretation regarding the extent of the Genesis flood. Traditionally the Biblical flood narrative has been understood to refer to a universal catastrophe, but on the basis of considerations from the natural sciences, commentators and interpreters began to seek for a limited flood theory or relative view of the Genesis flood. Published in Origins v. 2, n. 2.

This new concept indicates that some events in the past history of the earth may have proceeded much more rapidly than was previously believed. Published in Origins v. 2, n. 2.

Claimed correlation of C-14 ages with depth is not a sound argument for the accuracy of C-14 dates because in the great majority of cases, a linear relationship between depth and C-14 concentration does not exist. Published in Origins v. 2, n. 1.

A tiny marine worm, Spirorbis, constructs a calcareous tube, and is often found attached to shells and debris in the ocean. Fossil Spirorbis are sometimes common in coal beds. Some have suggested Spirorbis lived in fresh-water habitats in the past, but this is highly unlikely. It is more likely that coal formed in marine waters during the Flood. Published in Origins v. 2, n. 1.

The words "burst forth" correspond to the words "were opened" and the expression "the fountains of the great deep" corresponds to the "windows of the heavens." This chiastic parallelism indicates that the waters below the ground came forth as the waters above the ground broke loose. Published in Origins v. 1, n. 2.

A review of the book, Darwin Retried: An Appeal to Reason. the evidence for evolution is so weak it should not be considered a valid theory. Creation is not favored either. Published in Origins v. 1, n. 2.

A review of the article, Non-Poisson Distributions Observed During Counting of Certain Carbon-14-Labelled Organic (Sub)Mono-Layers.Small anomalies in counting C-14 disintegrations are probably explained by the experimental conditions and do not offer help for reducing the chronology based on C-14.
