Stability of Organic Molecules: Lessons from Vitamin C
The stability of organic (carbon-based) molecules is an interesting and challenging topic as there are many different types of functional groups, molecular configurations, and molecular collisions to consider. Research on the stability of ascorbic acid (Vitamin C) and other vitamins demonstrates which factors to consider when it comes to the preservation of carbon-based molecules. Ascorbic acid…
Sabbath, Creation and Redemption
The Sabbath, a day set aside to honor the Creator, provides an important opportunity to review briefly two spiritual riches, among many, of the Genesis Creation narratives.
The Geological Story Told by Iceland
Iceland is a volcanic island in the North Atlantic Ocean, slightly below the Arctic Circle. The island is situated on a mid-ocean ridge at the boundary between the North American plate and the Eurasian plate. In Iceland, we find evidence of horizontal movements, in which two plates spread apart as the crust dilates with intrusion of new magma. Iceland, however, is also associated with a mantle plume (a narrow stem of upwelling of magma from deep in the mantle) that has maintained volcanism high and vigorous.
Questions: Their Role in Discovery
When we are seeking answers, it matters a great deal what questions we ask. That seems obvious, but asking the right questions does not always happen automatically. And one of the important questions is “can I expect to know the answer to this question?”I am especially thinking of questions and answers relating to faith and science: questions about origins and geological history. First of all, consider…
Coping with Difficult, Unanswered, and Unanswerable Questions
Difficult, unanswered, and unanswerable questions are often catalysts for paradigm shifts in technology, medicine, and in personal and community value systems.Challenging questions important to Christian value systems are often about origins, evolution, pain and suffering, age of the earth, and various creation scenarios. Christian education has a responsibility to help individuals learn how to honestly…
Alpine Ophiolites: Remnants of a Lost Ocean
In 1813, French geologist Alexandre Brongniart published a paper on the mineralogical classification of rocks where he introduced the new name “ophiolite” for a suite of dark rocks rich in the mineral serpentine. The name was coined from the Greek words for “snake” and “rock,” which seemed fitting, given the smooth dark green appearance of ophiolites, vaguely reminiscent of snake-skin.
The Exceptional Properties of Water
There is one small molecule that makes our world unique and special. What is it? Water! Sure, other planets and moons in our solar system may have (or had) water and even more than Earth, but it is rare to find liquid water on the surface of a planet.
Fossils of the Galápagos: A Review with Implications for Creationist Models
Volcanic outcrops in the Galápagos Archipelago do not appear to provide the wealth of specimens found in other fossil-rich localities around the world. However, fossils are indeed present in the Galápagos Islands. This brief review addresses the where, what, when, and why of fossils in the Galápagos Islands and closes with a discussion of their potential contribution to the development of models on…
This point cannot be overestimated. Galileo wasn’t fighting against the Bible, but against an interpretation of the Bible dominated by the prevailing scientific dogma, which for centuries had been Aristotelianism.
The term Cenozoic (or Cainozoic) means “recent life,” implying that the fossils encountered in these layers are more similar to modern species.
Few things in science evoke more interest in children than dinosaurs. Books, films, toys, etc. continue to fuel kids’ interest in the very alien world of our past, yet few Christians know how to respond to their children’s curiosity in a way that is both biblically sound and scientifically accurate. Although a full discussion of the fossils in Mesozoic rocks would require several volumes, a brief synopsis is presented here along with some creationist reflections for those who are interested – parents or otherwise.
The Paleozoic Rock Record: A Broad Overview of Features and Trends
The rocks of the Earth are like pages of a history book containing information about the past. Geologists who enjoy reading this “book” have found that it consists of two “volumes:” the first, named Precambrian, is mostly devoid of macroscopic fossils. The second, named Phanerozoic, contains layers and sediments providing a rich archive of past forms of animal and vegetal life. The Phanerozoic “volume”…
The Precambrian: Part 3 of 3
This third part of a series on the Precambrian provides two perspectives suggested by creationists on how to interpret this portion of the rock record.
The Precambrian: Part 2 of 3
This second part of a series on the Precambrian describes Precambrian rock exposures, as well as the atmosphere, climate, and Precambrian life. Many illustrative pictures are included, and design examples and creationist ideas are interspersed throughout.
The Precambrian: Part 1 of 3
This first section of a 3 parts series on the Precambrian summarizes the standard model for formation of the Universe, Solar System and Earth, Moon, oceans, continents, and plate tectonics. Brief references to the Universe, Sun, and Moon are included because what happens beyond Earth sets the stage for what happens on Earth during the Precambrian and in the Genesis 1 account.
What Is Biology? Part 4 of 4
There is no simple clear definition of what life is. This is appropriate as life is a wonderful, complex, beautiful, enigmatic phenomenon that defies any effort to over-simplify it. Still, most people have no difficulty recognizing living things and differentiating them from non-living things.
What Is Biology? Part 3 of 4
The scientific method uses inductive reasoning to generate theories that explain data. Deductive reasoning is used to generate testable hypotheses that must be true if a theory is true. When the hypothesis is tested, it may fit well with the new data generated, thus supporting the theory (but not proving it true). If the hypothesis is inconsistent with data, then the theory is inconsistent with data…
What Is Biology? Part 2 of 4
There are still some rules that we have to follow if we are to do any science, including biology. The first is that empirical data is the authoritative test of all ideas in science.
What Is Biology? Part 1 of 4
Biology is the scientific study of life. But what is “science?” And what is “life?” Most of us use these words all the time and have a general idea of what we mean by them, however, it is common for scientists themselves to not have a clear understanding of what science is and this is not as surprising as it sounds. Philosophers of science struggle to define their own area of study, with different…
Mineralogy: A World of Law and Beauty
This article provides an introduction to mineralogy and outline the different mineral categories, discusses some interesting features about minerals, describes the formation of minerals in different environments, and mentions some minerals referenced in the Bible.
