Those that successfully met basic human needs – from the need to survive to the need to know – have played a big part in shaping our world. O ur world is very principle that already existed, needing only different from the to be found. But it is often difficult to tell world of our ancestors. where invention ends and discovery Tens of thousands of begins. Whatever they are, few inventions inventions and or discoveries are made overnight. There is discoveries have usually a period of preparation before they transformed the way we do things and the emerge. Even then, they take time to act. way we think. An invention is something An invention may take years to displace new, created by arranging things in some existing methods. A discovery may take novel way. A discovery is a thing or generations to change habits of thought. W ? hen did it happen This is not a book of “firsts”. I have listed It is often difficult to most inventions and discoveries under the date when they were first made public. But some dates relate to the beginning of tell where invention something that only later became well known, or to a later stage of something that took time to influence people. It can ends and discovery also be difficult to say exactly who invented or discovered something. Often, when the time is right, many people come begins, and neither up with the same idea. And making an idea work can be more important than simply thinking of it. At the top of each happens overnight. invention or discovery, I have named the people who I think contributed most to it. vk.com/englishlibrary 4 US_004-005.indd 4 05/02/14 11:59 AM Below, where possible, I have We may soon know enough mentioned others who helped or attempted something similar. Some stories are too interesting to control the machinery to squeeze into a small space. I have given these either a separate box or two whole of life itself, making the pages. These longer stories show how complicated inventing or discovering can future less certain. be, and how it can change people’s lives. Other aspects of these lives appear at the foot of most pages in a timeline, which records events in the wider world. and discoveries have had a lasting effect. Some, such as windmills or the theory of F aster and Faster continental drift, vanished for a while but Over the centuries, inventions and were born again. Others, such as pottery, discoveries followed two main trends. have never been replaced. Inventions and Ancient ideas became modern science as discoveries like these were used or measurement and mathematics improved remembered because they met basic human on observation and argument, and the way needs.
