Compared with the age of the earth itself, the age of human civilization is very short, and it has only been six or seven thousand years. Although human civilization is very short-lived, it has developed very rapidly, especially in the past hundred years, human science and technology has developed rapidly like a rocket.
Today I will share with you some ancient civilization discoveries. These ancient objects in the history of human civilization will look very childish and ridiculous from the perspective of today. However, when their appearance was at that time, each of them had epoch-making significance and had an important role in promoting the advancement of human science and technology. For example, the oldest battery above is still unfathomable to understand what the ancients 2,000 years ago wanted to use electricity to do. There is a saying that the ancients may have gilded the statue in this way.
The reason why people are different from wild beasts is that humans are civilized. In the process of human civilization, humans have gradually abandoned uncivilized behavior, and wild beasts can never do this. The picture above appears in the public toilet in the ancient Roman city of Ephesus around the first century AD, and it also has a flushing function. Don’t underestimate this invention. Just look at the smelly medieval Europe. You will know that the ancient Romans who lived 2,000 years ago were too smart.
In ancient times, many people died due to drowning. This is because ancient technology was relatively backward and lacked effective anti-drowning equipment. But humans are born close to water. Even though they know that water is dangerous, they still can't resist the temptation of water. This is true until today. Many people drowned due to swimming in the wild every summer. Although the ancients sometimes used dried gourds, bamboo tubes, etc. as lifebuoys, they were not easy to use, and the key also affected the movements during swimming. In 1925, an Italian designer transformed a life jacket with bicycle tires. Although it looked very weird, it was really useful and saved many lives.
You read that right. This caliper similar to the modern vernier caliper actually has a history of more than 2,000 years. It is a relic of the New dynasty period. Whether it is appearance, function or principle, this caliper is the same as modern vernier calipers. The only difference between the two is the different manufacturing process and accuracy. This caliper was indispensable for ancient craftsmen to make some precision equipment. But for some reason, this caliper was lost later, maybe because the design concept was too advanced!
This is not alien technology, nor is it future technology. People invented this single-wheel motorcycle as early as the 1930s. Although nearly a hundred years have passed, these single-wheel motorcycles and those in the photos are actually the same generation of products. Just like the so-called " new energy " car that is popular in modern times, it is actually no essential difference from the products 100 years ago, and both belong to the same generation of products. How about it, aren't you surprised?
Automobile is an outstanding product of modern human civilization and has made outstanding contributions to the development of human civilization. Compared with the modern fuel vehicles running all over the streets, many people may not imagine that the first car in human history with a speed of over 100 kilometers per hour was the electric vehicle , and it appeared in 1989, more than 120 years ago. You know, we were still in the period of the Qing Dynasty, and most people had never seen electric lights before.
1914, Edison took a photo with an electric car. Electric cars were technically very mature at that time. According to the experiment done by Liver Fritchet by , they could run about 144 kilometers on one charge, which was almost the same as the range of many modern small electric cars. However, due to the later rise of the oil industry, people turned to the research and development of fuel vehicles, and electric vehicle technology stagnated. By 1930, there were no electric cars on the market. Who knew that after a hundred years, the old object of electric vehicles appeared in the form of "new energy". It is really surprising.
