Science is the study of the physical world, that is, of God’s creation. None of these subjects can be approached without a sense of wonder. It is fitting, therefore, to begin by looking up at the heavens, at the lights in the sky: Astronomy. Then we take a look at the world God created (Geology), the creatures he created (Biology), and the intricate substances of which all things are made (Chemistry). We end by gaining an understanding of the nature and properties of matter and energy (Physics).
