In this book the author shares his
fascination with the elements that go to make up the periodic table. He follows
no scientific order in introducing them, preferring to group them in sections
labelled Power, Fire, Craft, Beauty and Earth.
In Power we have the traditional riches of
gold, silver and platinum along with the energy providing likes of carbon and
plutonium. Fire includes the most reactive of elements such as sulphur, potassium,
phosphorus and radium; while Craft covers the malleable metals – long
discovered tin, iron and copper along with more recent additions of zinc,
tungsten and aluminium. Beauty looks at the colour giving elements, both the
physical tints of cadmium, chromium and cobalt and the bright light producing
argon and neon. The Earth, or ‘rare earths’ elements are more recently won from
the ground, the likes of scandium, strontium and yttrium, unsung but
increasingly useful in modern industrial processes. These are just examples -
there are of course over a hundred to go at, and he covers them all.
Although the chemical properties are
covered, of more interest to the lay reader are the cultural references that
have attached themselves – how they arose and are perpetuated independent of
updated scientific reality.
Another interesting strand of the book is
the human stories behind the discoveries made; the search to fill the gaps
predicted by the periodic tabulation and the research into the chemistry and
physics behind its organisation.
The trends and fashions in naming new
elements is also of interest – Greek & Roman mythology (cerium,
promethium), places (germanium, francium, scandium, californium), recently
discovered planets (uranium, plutonium), and scientists (einsteinium,
rutherfordium, mendelevium). Geology
also gets a look in (mining engineers often at the forefront of discovery) with
Samarium.
Aldersey-Williams gets the balance right
between science, history, biography, economics and trivia, making for a book
packed with interesting information, obscure detail and memorable anecdotes.
