Development of Tools Throughout Time

Developing tools over time Today, there are various kinds of tools in our world. A few weeks ago, I noticed this when I passed Home Depot. The island has nails and screws, and the adjacent island has an electric drill, an electric saw and an electric sander. Now imagine there are no tools in the world, no nails or screws. It is very difficult to do most things. We do not have a house, we do not have a car to go to work, nor place to work.

Science is always the most commonly used tool in the history of traffic and can evolve over time. For example, the first means of transportation is a horse. Then people will realize that horse riding is uncomfortable, then make a tank. Through simple physics (science), it is easy for people to accomplish this As the years go by, tanks will gradually evolve into cars. However, in the 1900s people noticed that horse manure caused a large amount of pollution, so it was regarded as an alternative to prevention of pollution when gasoline vehicles were introduced to the public. But now, we know that gasoline cars are destroying the environment.

Throughout history, technology was always a promoter. The invention of the motor has revolutionized transportation and replaced the horse with a bicycle and a car. During the industrial revolution machinery and tools expanded exponentially. Our day-to-day communication has evolved from telegraph, telephone, modern mobile phone, and the Internet. Before introducing each technology, everything works well, people are "ordinary" living. Since it is not necessary to immediately improve what is not destroyed, the beginning of each innovation is usually late and has little effect. However, we are now aware of the importance of accepting these changes.
