Did You Know?

When Roman mapmakers drew a land area that no one had yet explored, they often labeled it "Terra Incognita"—that is, "Unknown Territory"—and the term continued to be used for centuries afterward. When Columbus and his successors first crossed the Atlantic, they entered upon terra incognita, a land that came to be called the "New World". But the term is just as useful for mental exploration. For most of us, subjects such as particle physics, French 17th-century drama, and soil mechanics are terra incognita, and we can only hope to live long enough to be able to explore some of them someday.
