The widespread availability and common use of computers has revolutionized chemistry, as it has almost anything else in human activity. In the 1970s a new generation of chemical operators was bom computational chemists, whose tools, rather than test tubes, are electronic computers. The following applications of computers in chemistry are relevant to the subject of this book  

Computers and computing times are becoming cheaper and cheaper. Rather than a dearth of machine time, the main problem of computational chemistry is more 

There doesn t exist a category of science to which we can give the name of applied science. There are science and the applications of science, bound together as the fruit to the tree which bears it.
