The 4th volume of this comprehensive work features hundreds of serial killers from Sacramento to Soviet Russia—plus numerous unsolved cases. The World Encyclopedia of Serial Killers is the most complete reference guide on the subject, featuring more than 1,600 entries about the lives and crimes of serial killers from around the world. Defined by the FBI as a person who murders three or more people with a hiatus of weeks or months between murders, the serial killer has presented unique and terrifying challenges to have walked among us since the dawn of time—a fact this extensive record makes chillingly clear. The series concludes with Volume Four, T-Z. Entries include the Terminator Anatoly Yuriyovych Onoprienko; Trailside Killer David Joseph Carpenter; Vampire of Sacramento Richard Trenton Chase; and the Voroshilovgrad Maniac Zaven Almazyan; plus the unsolved cases of the Adelaide Child Murders; the Axeman of New Orleans; the Chillicothe Killer; the Dead Women of Juarez; the Korea Frog Boy Murders; and the Volga Maniac.

In the history of mathematics there are many situations in which cal- lations were performed incorrectly for important practical applications. Let us look at some examples, the history of computing the number ? began in Egypt and Babylon about 2000 years BC, since then many mathematicians have calculated ? (e. g. , Archimedes, Ptolemy, Vi` ete, etc. ). The ?rst formula for computing decimal digits of ? was disc- ered by J. Machin (in 1706), who was the ?rst to correctly compute 100 digits of ?. Then many people used his method, e. g. , W. Shanks calculated ? with 707 digits (within 15 years), although due to mistakes only the ?rst 527 were correct. For the next examples, we can mention the history of computing the ?ne-structure constant ? (that was ?rst discovered by A. Sommerfeld), and the mathematical tables, exact - lutions, and formulas, published in many mathematical textbooks, were not veri?ed rigorously [25]. These errors could have a large e?ect on results obtained by engineers. But sometimes, the solution of such problems required such techn- ogy that was not available at that time. In modern mathematics there exist computers that can perform various mathematical operations for which humans are incapable. Therefore the computers can be used to verify the results obtained by humans, to discovery new results, to - provetheresultsthatahumancanobtainwithoutanytechnology. With respectto our example of computing?, we can mention that recently (in 2002) Y. Kanada, Y. Ushiro, H. Kuroda, and M.
