|Four Elements: Water, Air, Fire, Earth
||Profile Books, 2005||ISBN: 1861972342
There are now nearly 120 elements known, and these don't include water, air, fire or earth. But these original four still hold an important place in the history of science. Rebecca Rupp's book Four Elements uses them as the inspiration for a collection of essays, looking at science, history and a great deal more besides. Sometimes the connection is fairly straightforward, for instance ocean currents, geology and weather link directly to water, earth and air. For other subjects the path is more indirect, for instance air links to air-bourne molecules and so to perfumes and on to the measures taken in biblical times to keep secret the location of frankincense trees.
