In 1974, Berlitz published The Bermuda Triangle, a potboiler of a "non-fiction" book that listed the various disappearances, embellished them considerably and offered a variety of explanations, some more ludicrous than others, for the trend, including alien kidnappings, lost technology from Atlantis, dimensional portals opening as the result of freak magnetic storms, and a hazy theory having to do with time travel.

1974年，伯利兹出版了一本粗糙滥制的"非小说类"图书——《百慕大三角》，列述了各种失踪事件，对其肆意添枝加叶，并且对这种趋向提供了多种解释，有些解释比其它解释还要荒唐，如外星人绑架、亚特兰蒂斯的失落科技、由奇异磁暴造成空间之门的开启，以及与时光旅行有关的模糊理论。

The property of being a prime is called primality. Prime numbers are of fundamental importance in number theory.
