“Some greatest inventions to change the world.”

There could not be any development without inventions. Modern world can be called the world of technology, but the way to this title was rather long. Nowadays there are numerous laboratories discovering something new on a daily basis, but there are some inventions that date back centuries, but are still the core of the modern science. Almost all of contemporary discoveries have been based on previous inventions, so we should give credit to those talented inventors, who laid the foundation for our comfort. Let us remember the most crucial inventions and their creators, who paved the way to our easy-going life.

Wheel is one of the most ancient people’s inventions. It is the thing that lets us move nowadays, but became a revolt in manufacturing hundreds of years ago. It is supposed that a wheel was discovered 3,000 years ago by potters and helped to carry different goods. It was a real boost when the wheel was enhanced to the extent that it became a part of the vehicle. The invention of the wheel is a concept that lay grounds for many other inventions we can not live without.

Telephone is one more revolutionary idea for people’s communication. Though the idea of it is rather simple, it took many years to realize it in real life. Michael Faraday, Johann Reis, Alexander Graham Bell have worked on the telephone equipment and the last inventor managed to reach his target and even founded the first telephone company. This company is also regarded to have developed the first mobile phones for police and later set the pace for cells development. It is impossible not to remember a refrigerator as one of really impressive inventions. Though its appearance is connected with many names, the concept of a refrigerator originates from 1800s. The greatness of this invention implies the ability to prolong life of many products in cold environment and it has given a stimulus for the development of food production industry on a new higher level.
