During old times, scientific innovations were made and they were very helpful. Here in this article I will talk about the wheel, compass, internet, batteries and refrigerator which are the science innovations that changed the world.
First, Wheel was invented by David Anthony in 3,500 BC. Well, creating a wheel wasn’t a big deal but to connect them with the rolling cylinder got tricky. According to David, he used the wheel and axle method to make it happen. Wheels are very necessary in our life because they help us to transport goods from one place to another. It is used in vehicles from which we can travel.
Second, the compass was invented in China by Chinese people during the Han dynasty. It was intended between 2nd century BC and 1st century AD. However, it was used for navigation for the first time. The earliest compasses were designed on a square shape that had markings for the cardinal points. The pointing needle was a spoon-shaped lodestone with a handle that would always point south. Compass allowed us to go across the oceans easily and was very easy and helpful to explore different places of earth. This way people could find new places as well.
Third, the internet has an evolutionary background. A computer programmer named Tim Berners-Lee from Switzerland invented the internet. The Internet was invented on January 1, 1983. The internet is important for us because it helps us in our daily lives in different ways. For students, it makes it easier for them to study, write articles, poems, essays, etc. For teachers also it is very helpful as they can use Google classroom to teach and earn more knowledge through the internet and it is also very helpful for career because from a lot of occupations on the internet we can earn enough money to eat and live a proper life.
Fourth, batteries are so essential in our daily life for different reasons. The first battery was made in1800, by Italian physicist Alessandro Volta. Slowly a lot of other processors discovered it and created batteries which can be used in electric vehicles. Batteries are also very important because, as we all use it in different devices like remote control, ac remote, etc. It is also used in robots, electric vehicles, etc.
Fifth, refrigerators are very important in our daily lives. We all have probably used it as well. It was created by William Cullen in 1834 and when a vapour-compression system was developed by Jacob Perkins In 1876 they created another commercial refrigerator. Refrigerators are very helpful for us as they help us to keep food cold. We can keep leftover food in the refrigerator as well so that it wouldn't get wasted.
In conclusion, All these inventions are very important and helpful in our daily lives. It helps us to do a lot of things in our daily lives and we can make our work faster and easier.
