The author predicts many dire events, starting with the birth of Hitler in the 1800s and through WWIII which will end in 1993. The author's confidence is based on his newfound ability to calculate the number 666 as directed in Revelation. The author -- whose experience was in systems analysis in civilian and military life -- began the calculation in 1972. "For two years there seemed to be no way to run down this Ultra Secret. Then suddenly clues began to multiply with the discovery that the alpha-numeric languages of the Bible were written in thought language (DANTL). The understanding of DANTL greatly simplifies the calculation. The results became apparent early in 1982."
