What is technology? Technology is the science and art of making and using things.  Humans can turn the materials of the natural world into tools, and machines that help them to live.  But...

Human technology is different: people are able to see new needs, find new ways of meeting them, and to recognise the value of accidental discoveries. Over the last few centuries, scientists have found out why certain materials and machines behave the way they do.  This knowledge has been brought to bare to improve and even develop new materials.  Scientists, engineers and designers now have a vast range of materials, methods and components they can use to realize their ideas  ... and sophisticated computers helps them to fully realise these idea.  But producing something that works well, costs little, and appeals to its users, remains a truly human art.
