The present would not be like today if there were not some discoveries or innovations from ancient scientists. Try to imagine if there were no vehicles, computers, or smartphones, what would life be like now?
For this reason, we must be grateful for the hard work of past people who created several useful items which we still use today. The following are ancient technology inventions that in fact we still use today.
1. Battery Electric
The need for electric power is very high. Not only now, hundreds of years ago humans really needed electricity. The need for electric power that can be carried anywhere is what prompted ancient scientists to create a technology called the battery. Yes, the electric battery was invented by a scientist named Alessandro Volta in the 1800s.
Alessandro Volta is an Italian physicist who managed to find an electric battery. Volta created an electric battery using zinc and silver discs that are positioned specifically in a cylindrical stack. The battery managed to generate repeated sparks and helped move a lot of things.
At a time when the world of health was not as advanced as today, people in ancient times were so afraid and panicked when a disease was known. Is the disease severe, is there a cure, and so on. Luckily at that time, a vaccine was found. Discovered by Edward Jenner in 1796.
In 1796, at that time the world was terrorized by the endemic disease smallpox or smallpox. If left untreated, people can die from smallpox. And again, this disease is very contagious. Jennersucceeded in finding a vaccine that can be used to treat smallpox. The vaccine later saved many lives and he was given the title Father of Immunology. Now, vaccines are growing and can be used to treat several diseases.
3. Steam Engine
The presence of a steam power engine immediately created a revolution in the industrial world. Found long ago, the existence of the steam engine is still used today. Several modes of transportation still use steam engines. Examples are excavators or dredgers, buses, trucks, and there are also bicycles with steam engines.
Steam engines work by using heat in water vapor and converting it into mechanical energy. Is the discovery of a scientist named Thomas Newcomen in 1712. Since the discovery of the steam engine by Newcomen, his invention is used for stationary pumps or engines. Don’t confuse this with the steam train invented by John Blenkinsop in 1804.
Alarms are great for helping someone get up early on time. If you wake up late, you must have an alarm clock beside your bed. Although many people have been helped by the existence of an alarm clock, not many people are aware that if ancient scientists did not invent the alarm clock, there might be many people who would be late to work or school.
Traced more deeply, alarm clocks date back thousands of years, in Ancient Greece. In that era, the existence of a clock with an alarm has become a very luxurious technology. Of course, the shape of an alarm clock in Ancient Greece was not the same as that of an alarm clock today. Plato said he had a large water clock with an alarm signal similar to the sound of a water organ. Plato used it at night to mark the beginning of class.
Calendar, with this one object, we know the date, month, year, when to change the year, and the determination of other important days also depends on the calendar. Today’s modern calendar, we know there are 12 months that start from January and end in December. Each month, contains 3 weeks, consisting of Monday-Sunday.
The modern calendar wasn’t invented until finally in the 1600s. Prior to that, there were countless versions of the calendar. Each calendar was created with a different writing, time, and purpose. The first calendar used by the Egyptians was the solar calendar. Then, Julius Caesar created the Julian Calendar which consists of 12 months. Having a weakness, the Julian Calendar was refined by becoming the Gregorian Calendar, introduced by Pope Gregory XIII in 1582.
The presence of computers today can no longer be ignored. From those who help count and count, until there are many people whose jobs depend on computers. Because of the importance of computers, education about computers has started early. Even elementary school children and even kindergartens have been introduced to computers.
The first computer created by humans was a computer made by J. Pesper Eckert and John Mauchly at the University of Pennsylvania. Making computers began in 1943. At that time, the size of the computer was very large, as big as a room with a size of 167 M2. A computer that big, weighs too much, 50 tons.
In ancient times, people realized that water could be a source of energy or at least provide great benefits, especially for agricultural fields. Therefore, a waterwheel was made. This waterwheel is used for various things such as forming metal, agriculture, and milling.
This waterwheel has been around since time immemorial, around the 3rd century BC in Greece. In the past, the name wasn’t a water mill, but the Perachora wheel. Made by a Greek engineer, Philo if Byzantium. However, Philo had said that his creation was not original. The Arabs were the first to create it. British historian, M.J.T. Lewis who proved that the original waterwheel from Ancient Greece.
If only that compass didn’t exist, it would be some human way to go somewhere. Those who were lost on the mountains, without the existence of a compass, would find it difficult to get down and return safely. And, you all need to know, this compass was actually created by scientists from China. But with a different original purpose.
By the ancient Chinese, the compass was originally made to predict something. Nobody used it for directions until they finally realized the other benefits of the compass in the 11th century AD. The way this compass works uses the natural magnetic field from the Earth which later moves the needle in the compass.
Although the car was born in 1886 by a German scientist, Karl Benz, it was not immediately available for everyone. Until the 20th century, Henry Ford created new innovations by producing cars on a large scale. He created a car that later became a world standard with Ford, General Motors, and Chrysler.
The history of cars is not only that. Many companies ended up creating cars at that time. Creating many cars to be used as vehicles requires a lot of labor. By starting to advance the car industry, it will increase job opportunities for those who are able and want to work.
Imagine how difficult life would be if the wheeled vehicle was not round. If the shape is square, ellipse, or triangle, will we be able to get to our destination? Luckily the shape of the wheel is a circle. It turns out that the presence of this wheel has been around for a long time, the shape is the same as it is now, the most different thing is the size.
The existence of the wheel has been studied since 3500 BC. At that time, the wheel was used by humans as a tool to move goods from one place to another. And, when this wheel was created, it was not originally used as a wheel for human transportation such as cars or motorbikes.
