![]() ![]() ![]() "If it were my date stone," Cassandra said dryly, "I'd prefer the entwined hearts. "My guess is whoever chiseled that symbol was a mathematician or scientist." But a mathematician named Leonhard Euler found a way to treat infinity as if it were a finite number- and that allowed him to do things in mathematical analysis that had never been done before." Tom inclined his head toward the date stone. The problem with infinity, of course, is that you can't come up with a final answer when the numbers keep increasing forever. "Back in the eighteenth century, there were certain mathematical calculations no one could perform because they involved series of infinite numbers. ![]() "How is it different from the usual one?" Do you see how one line doesn't fully connect in the middle? That's Euler's infinity symbol. "You think it was the symbol for infinity?" Unless." She paused as understanding dawned. “But that would mean it was originally a sideways number eight. ![]()
