Since the turn of the new century, a theory has emerged concerning the end of the world, or at least the end of life as we know it. This new theory centers around the year 2012, a date that many claim has mysterious origins in ancient manuscripts from many different cultures. The most noted characteristic of this date is that it appears to mark the end of the Mayan calendar. But there is no evidence to suggest that the Maya saw any great relevance to this date. In fact, none of the claims surrounding a 2012 doomsday event hold up to scientific inquiry. The year 2012 will pass without a major, life-altering catastrophe .
Longer essays may also contain an introductory page that defines words and phrases of the essay's topic. Most academic institutions require that all substantial facts, quotations, and other porting material in an essay be referenced in a bibliography or works cited page at the end of the text. This scholarly convention helps others (whether teachers or fellow scholars) to understand the basis of facts and quotations the author uses to support the essay's argument and helps readers evaluate to what extent the argument is supported by evidence, and to evaluate the quality of that evidence. The academic essay tests the student's ability to present their thoughts in an organized way and is designed to test their intellectual capabilities.
