Human thought can go so far that it is hard to imagine. The most unexpected discoveries and inventions can completely change the world, turn it upside down, affect every person on the planet. We will consider the most interesting inventions in this article.
Language and numbers
Undoubtedly, language can be called the most useful and interesting invention of all time. Now it is hard to imagine that some couple of thousand years ago it did not exist. Of course, there were certain generally accepted gestures and sounds to denote certain objects or phenomena, but there were no words for metaphysical concepts, for what cannot be seen. Therefore, the language can partly be called one of the engines of progress. The same can be said about the numbers, without which we cannot imagine our lives.
Alcohol
Some, of course, will say that alcohol is not an invention, but thanks to alcohol, a lot of useful and remarkable things happened.
Despite the fact that now from himnot so much good, in the Middle Ages he was a real salvation. Indeed, at that troubled time, clean water was a rarity, and people had to drink low-alcohol drinks in order, firstly, not to get infected with anything, and secondly, to slightly increase their immunity so that it could withstand viruses and bacteria. Interesting inventions of mankind can take this form.
Printing
You will be very surprised, but some interesting inventions of mankind appeared quite recently, and without them the world would be completely different. This applies, first of all, to printing, which was a huge breakthrough on the path to civilization, because before that any work had to be simply copied by hand, which did little to stimulate the widespread development of literacy. The first printing press was created by the German inventor Gutenberg in the middle of the 15th century. He became popular very soon.
Internet
Initially, after the invention of the Internet, no one could have imagined that just a few decades later it would gain such popularity and be used everywhere around the globe. Moreover, at first the Network had completely different tasks.
The Internet was used only for very serious research and military purposes, and soon after personal computers became more or less accessible, it spread around the world. In a matter of years, the number of Internet users has reached an incredible number. Today, a third of people on the planet have access to the Internet.
Interesting inventions at home
Of course, most high-tech gadgets and complex devices cannot be made at home, but there are useful and simple things that even a child can create. For example, if necessary, you can make real gunpowder. Interesting DIY inventions will require some materials. So, to make gunpowder, you need to prepare coal, sulfur and s altpeter. All components must be crushed and mixed in a ratio of 18:17:65 percent, respectively. Just remember to be safe!
3D printer
This invention appeared quite recently, but has already managed to make a lot of noise. At first, various little things and household items were made on it, but with the development of technology, a 3D printer began to save human lives. Now progress has reached the point that in this way it is already possible to create the internal organs of a person, which are so needed by people who need a transplant.
Robot Vacuum Cleaner
Maybe this is not as popular an invention as the above, but who said that interesting inventions can't just be useful in everyday life? A robot vacuum cleaner is not just a way to save time cleaning your home. Due to the fact that most modern models can not only vacuum, but also wash the floor, such a device can be a great helper for people suffering from allergies.
Hydrogen-powered tram
A breakthrough in the search for environmentally friendly fuels has already been made. ATChina has created the first tram that does not pollute the world around, because it runs on hydrogen. Such a tram is capable of traveling a hundred kilometers without refueling, despite the fact that it is designed for almost four hundred people.
Transparent toaster and hot knife
This is another useful invention for those who don't like burnt toast. Such interesting inventions not only pleasantly improve life, but also help save a little time, which is especially valuable in the morning. Roughly the same can be said about the heated knife. If you ever need to butter the bread, which doesn't like to spread evenly on the sandwich, just use a hot knife, which will heat the butter up a bit along the way.
Something else?
Of course, every day dozens of new inventions appear in the world, sometimes incredibly strange and of little use. But interesting inventions continue to excite the minds of successful scientists and not only.
Unbelievable things are constantly appearing on store shelves. They love to create such masterpieces in Japan. For example, quite often on the streets of this state you can find vending machines that sell used linen. Despite such a strange device, the level of development of robotics in Japan is at the highest level in the world. Here you can find robots designed for a variety of purposes.
Even though many differentdiscoveries have already been made, we continue to hope that new things and devices will be invented that will make our life a little more pleasant and easier. Who knows, maybe soon a new, super-powerful train will be created, and it will be possible to get to work not in an hour, but in five minutes. After all, such everyday things for modern man seemed something surprising and not probable before. But all this is only in the future, and in the present we can only use things that have already been created, the wisdom that scientists, researchers and random inventors have been accumulating for centuries.
