On Stellar
Structure and Stellar Evolution
Bruce
Briegleb, M.S.
Current stellar astronomy
maintains-a close relationship between the observed structure of stars
and their supposed evolutionary history. An attempt is made to distinguish
between stellar structure observations and theoretical stellar evolution.
The physical laws believed to govern the macroscopic structure of nondegenerate
stars are reviewed. From these laws, scaling relationships between several
properties are derived. These scaling
relationships hold independent
of the source of stellar power, allowing for both gravitational contraction
and thermonuclear fusion sources. With additional observational information
and physical approximation, a synthetic Hertzsprung-Russell (H-R) diagram
is presented. The synthetic H-R diagram bears some similarity to observed
H-R diagrams.
An Evaluation
of the John Woodmorappe Flood Geology Model -- Part I
A. W.
Mehlert, Dip.Theol.
In a 1983 issue of the Quarterly,
a creationist geologist published a carefully prepared and well-researched
treatise on the stratigraphic separation of fossils (Woodmorappe. 1983,
pp. 133-185).
In marked contrast to many
previous Flood models which proposed mechanisms and processes that were
rather simplistic and largely not compatible with the actual layout
of the rocks and the fossils they contain, John Woodmorappe's concept
appears to overcome most of these incompatibilities. It has been both
surprising and disappointing that this model has been almost completely
ignored by creation scientists and others, possibly because of its grand
scope and consequent complexity.
This paper evaluates, simplifies
to a limited degree, and elaborates on Woodmorappe's Flood concept and
thereby hopes to encourage more debate and interest in the field of
diluviology and geology, for unless creationists can suggest a reasonable
and consistent explanation for the earth's rock systems and the undeniable
separation of fossils, the evolutionary uniformitarian approach to geology
will continue unchallenged in its domination of earth sciences. This
paper (Part I) will discuss the precision of the geologic column. A
later paper (Part II) will evaluate the Woodmorappe Flood model.
The problem
of Extinction and Natural Selection
Jerry
Bergman, Ph.D.
The problem of animal extinction
was reviewed, finding that the literature shows that little evidence
exists to conclude that extinction occurs because of Darwinian evolution,
i.e., the least fit are more apt to become extinct than the better fit.
Researchers have been able to find few consistent differences in biological
fitness of animals which become extinct and those that have not. Today,
a clear tendency exists for the so-called higher organisms to become
extinct, as shown by an evaluation of endangered species lists and a
study of animals which have become extinct in recent history. Most types
of animals that have become extinct in the past are generally not less
fit than surviving types, are very similar to many extant types, and
any differences are often irrelevant to survival. The reasons for extinction
are either chance or unknown, not a pruning of the inferior species
as biological evolution predicts.
Fossil Wood
from Big Bend National Park, Brewster County, Texas:
Part II
-Mechanism of Silicification
of Wood and Other Pertinent Factors
Emmett
L. Williams, Ph.D.
A theoretical mechanism
for the silicification of wood is presented. Possible rapid burial and
silicification are discussed within the framework of a young earth model.
Laboratory means to implant silica in wood are reviewed. Autochthonous
and allochthonous deposition of woody material in various locations
is explored.
