Chapter 5 in the article, Life: An Evidence for Creation. 1. Everyday experience teaches us that manufactured goods with new functions are made from pre-designed components. 2. Successively more complex levels of our reality with new functions are based on the interactions of simpler forms of matter. This suggests that our complex reality is designed.

Any credence given to the study of mathematics must recognize that God is the original mathematician. And though, through the ages, humankind has experimented to be able to draw conclusion in the areas of mathematics, God's laws are error-free and constant. His everlasting watch-care in the "natural" cyclic phenomena of this earth daily prove His mathematical supremacy. Galileo is remembered for having acknowledged that "mathematics is the language that God used to create the universe."

It must be emphasized that Chemistry, like any other area of scientific knowledge, is neither good nor bad, but like everything else that was marred by the entrance of sin, man's ability to manipulate his environment has led to misuse. Instead of giving in to technicism, where technology sets the agenda for life on planet Earth, the ethics of the Bible should be the basis on which we make decisions on the value of life and on the conduct of life.

We need to develop ways to foster consciousness about the environment and a willingness to participate as good stewards of creation.

What is thought to be knowledge or information can usually be divided into two separate concepts: data and interpretation. Since data is subject to alternative interpretations, researchers must carefully distinguish between the information that constitutes the collected data and the "information" derived from the data that is presented as evidence in support of an hypothesis.

A review of the book, The Book of Life- An Illustrated History of the Evolution of Life on Earth. 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 "RNA World" hypothesis for the origin of life is implausible for several reasons, among them the difficulty of producing RNA naturalistically, its relative instability in water over time, the problem of chirality, and the insufficiency of RNA to form a living cell.
