There are many inventions that revolutionized their time and from which we still benefit today. Since the invention of writing and the wheel, there have been countless milestones in these fields. The most important inventions of mankind include mobility and communication. We present five inventions that have changed our world. It’s hard to imagine life without them.
The font
It is believed that the first written characters originated in China and are more than 6000 years old. It was the invention of writing that made it possible to pass on history and stories across generations.
The wheel
Opinions differ as to exactly when and where it was invented. What is certain is that wooden wheels dating back to around 3200 to 3500 BC have been found in both Switzerland and Slovenia. It is also certain that we would hardly have become mobile without the wheel.
Electricity
Electricity has actually always been around. The fact that people were able to harness the electrically charged particles is said to go back to Alessandro Volta in 1775. He invented the battery.
Airplane
The invention of the airplane made it possible to cover large distances in short distances. Its invention goes back to the two Americans Orville and Wilbur Wright, who launched the first controlled and sustainable flight with a motorized aircraft in 1903.
Computer and cell phone
The English mathematician Charles Babbage is said to have invented a calculating machine in 1822, which is regarded as the forerunner of the modern computer. However, the first computers in the conventional sense are said to have only been around since 1940. At that time, computers still filled huge halls. From then on, computers became smaller and smaller and could do more and more. We now even use them to make phone calls every day.
Inventions - blessing or curse?
Today, an estimated four billion people worldwide use a smartphone. A similar number of laptops and computers are in use. Since the invention of electricity, the number of electrical devices has increased almost explosively. While our grandparents were hardly exposed to any electrosmog, artificial radiation from electrical devices, cell phones, laptops and computers is a major issue today. This is because the low-frequency radiation emitted by electrical appliances such as televisions, stoves, ovens, fridges etc. is suspected of having a negative impact on our health. The effects of high-frequency electromagnetic radiation, which reaches us via mobile communications, are said to be even more severe. This includes transmission masts for communication such as televisions, radios and telecommunications.
