From the citation: [Florin]
Diacu (Univ. of Victoria, Canada) is a mathematician who uses his
professional and outstanding literary skills to provide a remarkable
analysis of the "science" of prediction. His chapter topics range from
tsunamis, earthquakes, volcanic eruptions, and cosmic impacts to
financial crashes and pandemics. Perhaps the most remarkable chapter
deals with climate change. All these subjects are highly germane to the
present world society awash with levels of communication hardly
envisaged 10 or 20 years ago. Diacu's great depth of historical
knowledge, penetrating insights, and familiarity with the associated
literature has led to an erudite yet easily readable approach that
retains critical scientific impact. In an age where the news media and
large sections of society seem to feast on dire predictions and the
threat of many "imminent" disasters, Megadisasters should be required
reading for all intelligent human beings. Summing Up: Highly
recommended. All levels/libraries.
