Most successful inventions do not rely on complicated technology In fact some of the world s greatest inventions have been very simple things To what extent do you agree or disagree

When people think of inventions, they often think of things which are technically complicated, or which require electricity in order to work. This is especially true in the 21st century, with our obsession for mobile phones, portable computers, digital cameras and other electronic items.

Many other great inventions are even simpler. A wheel requires parts which move. This means that compared with a paper clip, an elastic band or sheet of paper, it is quite complicated. But these smaller items are an essential part of every office. The same can be said for pencils, sticky tape, and many other stationery items.

Great simple inventions can also be found outside the office, of course. In my opinion, some of most important inventions are those which have a medical purpose. Aspirin and syringes, for example, have helped to relieve pain and prevent cure disease.

However, many of the inventions which have changed our lives have been very simple things. Without the wheel, for example, we would not have cars, motorbikes or bicycles. Aero planes would not exist, as they would not be able to take off or land without wheels. Furthermore, wheels, in one form or another, are an important part of many smaller machines, like watches and computers.

In a nutshell, I think that a great invention does not need to be complicated or technical. It can be something small or simple which has changed or improved our lives in some way. After all, most of us have a mobile phone, but it could not cure us if we became ill.
