From the polio vaccine to the Post-It, the personal computer to Prozac, these are the scientific and technological innovations that have transformed our world. Award-winning author Alex Hutchinson unveils the 100 greatest inventions of the modern era - starting with the discovery of the transistor in 1947 - complete with original photographs and anecdotes about their creation. For example, a candy bar melting in a scientist's pocket during an experiment led to the invention of the microwave oven. Hutchinson consulted 25 experts at 17 museums and universities; their collective expertise spans aeronautics, automobiles, biology, computers, medicine, physics and a host of other fields. The result includes some obvious breakthroughs (the laser, in-vitro fertilization) as well as a host of surprises (waffle-sole running shoes, the pull-top can). This charming book will delight, fascinate and educate.
