Query: A REALLY IRRITATING BOOK...

...within the text there exist so many arbitrary statements (such as Dr. Ps' belief that he has been chosen by God to lead the world into a scientific era of revelation, that modern science is dogma, ect., ect.) and arbitrary number tricks(that Plichta has stolen from old math-game-books, and claimed authorship of), that Dr. Plichta can be generally considered a fanatic without any merit at all. The mathmatics within, though completely unrelated to the prime number code, are interesting enough to make the reader come back out of no reason more than interest. However, Dr. Ps' negative attitudes towards modern physics and his delusions of being the greatest mind of all time, tend to irritate me. I recomend this book only to extremists who have completely shut the doors of open mindedness toward modern science.
