Columbia is preparing for an estimated million visitors to come this month to witness a total solar eclipse, a scientific phenomenon that inspires awe and wonder in those who view it. The world goes dark in daytime as the moon completely covers the sun. Imagine what it must have been like for people in the past who didn’t necessarily understand what was happening. Our understanding of the solar eclipse has changed, says Michael Weisenburg, who oversees the special collection of books at USC's Thomas Cooper Library. Among many USC events surrounding the eclipse, the Thomas Cooper library will display the collection of Robert Ariail, who acquired thousands of rare astronomical texts. South Carolina Public Radio's Laura Hunsberger has more on this story.
