Professors of Physics and Astronomy at Calvin College. Deborah, with a Ph.D from Massachusetts Institute of Technology, researches galaxies and cosmology; and Loren, with a Ph.D. from Harvard, studies electrical activity of nerve cells. Together, they have explored the science and theology of origins, speaking at numerous conferences, colleges and churches. In their book, Origins, they explore what both God's Word and God's world teach us about creation, the age of the earth, evolution, and intelligent design. Some views on origins reject modern science while others reject Christian theology, but there is a range of views that take both seriously. The Haarsmas summarize areas where Christians agree, while sympathetically presenting the strengths and weaknesses of positions where Christians disagree.
