A Shortcut Through Time

The newest Pentium chip powering PCs and laptops contains 40 million electronic switches packed onto a piece of silicon about the size of a thumbnail. Several years from now, if this incredible shrinking continues, a single chip will hold a billion switches, then a trillion. The logical culmination is a computer in which the switches are so tiny that each consists of an individual atom. At that point something miraculous happens: quantum mechanics kick in.

Anyone who follows the science news or watches 'Star Trek' has at least a notion of what that means: particles can be in two or more places at once. Atoms obey a peculiar logic of their own - and if it can be harnessed society will be transformed. Problems that would now take forever would be solved almost instantly. Quantum computing promises nothing less than a shortcut through time.

Reviews

Fascinating and highly accessible... Unpicking the complexities of the subject is not easy, but Johnson has done a fine job of it... [An] excellent book

—— Scotland on Sunday

Lucid and accessible... [Written with] a beguiling combination of clarity and enthusiasm

—— New Scientist

Johnson is one of the best science journalists writing today

—— Scientific American

Full of good stories and he knows how to tell them well ... an agreeable jumble of anecdote, reflection and information

—— Sunday Telegraph

Great fun to read and an endless fund of unlikely and improbable anecdotes ... sharp and often witty

—— Financial Times

A joyous romp through the chemical elements

—— Today, BBC Radio 4

Not only a cultural history of the elements, it is also a lament to the loss of science as a hobby

—— Economist

A flashily brainy book, crammed with literary references and held together by a personal quest to collect as many elements as possible

—— Telegraph

'Elements are fun' is the essential premise of Hugh Aldersey-Williams's new book and by heck he's right ... Aldersey-Williams mourns the fact chemistry isn't really sexy any more; Periodic Tales is a step towards it getting its mojo back

—— Metro ****

Imaginative and fun ... almost every page yields a nugget

—— Nature
