Various examples adequately establish that a radioisotope age does not necessarily have a real-time significance. A relationship of a radioisotope age with real-time must be based on an interpretation.

Most science is conducted under the philosophical assumption of naturalism. A few scientists are developing an alternative paradigm, here called interventionism (generally called theism). Published in Origins v. 23, n. 1.

A collection of short commentaries on scientific papers published in 1996, covering topics such as Homo erectus, the Permian mass extinction, mutations in Chernobyl rodents, dropstones, yeast genome, Heart Mt detachment, carbonate cycles, eye development gene, RNA World, Archaeopteryx, Cambrian chordate, turtles, stromatolites, and pseudogenes. Published in Origins v. 23, n. 1.

Study of the Bridgewater "Fossil Forest" of Victoria, Australia shows calcification of plants of two distinct appearances. One group is more superficial and consists of branching structures that appear to have grown in place. At a lower level is a series of layers of larger, hollow stump-like structures for which a suitable explanation is not known. Published in Origins v. 23, n. 1.

Scientific activities can be classified in a number of ways, but the suggestion here is to compare science with a naturalistic presuppostion, science with a creationist presupposition, or "methodological science," meaning inquiry open to either naturalistic or supernaturalistic explanations.

A review of the book, Grand Canyon: Monument to Catastrophe. Published in Origins v. 21, n. 2.

A review of the book, Dreams of a Final Theory. Attempts to explain all of creation from a naturalistic perspective have limited success. Published in Origins v. 22, n. 1.

Coconino Sandstone research has demonstrated how catastrophists can use their theory to develop specific hypotheses about a geologic feature (the Coconino Sandstone), and successfully carry out scientific research to test that hypothesis. This is one criteria that science used to determine the scientific value of any theory.

The catastrophic burial of plant debris and its subsequent change to coal is not accepted by most coal geologists. However, the dominant "peat bog" theory presents problems that have remained unanswered for more than a hundred years. A Flood model for the formation of coal answers some of these problems and provides a scientifically reasonable explanation for the origin of the vast quantities of coal that exist worldwide.

A review of the book, New Concepts in Plate Tectonics. The theogy of plate tectonics is questioned on geological grounds. Published in Origins v. 21, n. 1.

The fact that animals need plants poses a problem for the evolutionary model, since the record of past life sometimes reveals non-viable ecosystems. Published in Origins v. 21, n. 1.

This paper focuses on how values integration can be done in a mathematics classroom. Specifically, it aims to answer the following questions: 1) What are the moral, social, and spiritual values that can be integrated in mathematics teaching from an Adventist perspective? 2) How can mathematics be made interesting and relevant?

The philosophical context in which biology is presented can make an important difference in its meaning for the student. The philosophical worldview of the biblical Christian is quite different from that of the non-Christian; thus, the biology teacher may have a profound influence on the development of worldview by the student.

The oceanic patterns of magnetic anomalies are thought to be one significant evidence supporting the general notions of plate tectonics. Arguments are presented suggesting that important characteristics of the anomaly patterns could be due to the measurement process itself rather than being a direct reflection of geomagnetic reversals and plate movement. Published in Origins v. 20, n. 1.

It is unwarranted to assume a priori, as in the past that all upright petrified trees had grown in the place where they are now found. The transport of trees and their deposition in an erect stance is not as unlikely or as rare as might be expected. Upright fossil trees within the geological column are compatible with a Flood model. Actually, when all factors are considered, a catastrophe involving water and many floating trees is a more satisfactory explanation for their origin.

A collection of short commentaries on scientific papers published in 1991, covering topics such as Permian trees, molecular genetics, epigenetics, inheritance of paternal mtDNA, water and formation of petroleum, water in mantle rocks, impacts, Ordovician volcanism, molecular phylogenies of ratites, termites, cichlids and sabertooths, osteocalcin in dinosaur bones, fossil flowers, origin of life, Precambrian predation, stromatolites, Cambrian Explosion, quality of fossil record, rapid speciation, tree biogeography, Miocene ape, fossil dermopteran, Asian marsupial, dinosaurs, mammal-like reptile. Published in Origins v. 19, n. 2.

The pipes and dikes in Kodachrome Basin have come from the sedimentary layers below, and raise interesting questions regarding the amount of time involved in their formation. Published in Origins v. 19, n. 1.

The unnatural mixture and the rapid stratigraphic shifts of fauna seem to require catastrophic water transport into the area. The large geographic extent precludes a local event. Creationists suggest that a world-wide flood could produce results as seen in the Santana Formation and is a better explanatory model.

A review of the book, Portraits of Creation: Biblical and Scientific Perspectives on the World's Formation. This is a sophisticated criticism of creation science, and some of the points should be taken to heart by creationists. However, it fails to recognize the good quality of recent creationist literature. Published in Origins v. 18, n. 1.

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.
