3. The Internet. This is arguably the most important invention of all! So many of us would now be completely lost without it. Not only do we use it for our email, online banking, shopping, business management and social networking, but it is also an invaluable source of information! We can use it to find the answers to most of our questions and it will even provide us with an accurate weather forecast (well, most of the time!). If you were to take away the internet, then much of our society would now totally collapse. A scary thought indeed...
9 - The Computer - Many people have the deepest, richest, most diverse, and rewarding relationship with their computer. It plays games with them, tells them jokes, plays music to them, it does the taxes, and sometimes it' even used to work.
Computer is the greatest invention of science. It is the invention from all important inventions. Invention history is long about computer. It is not just a machine only. It works as calculator to solve mathematics, cassette player, television and so many.
