Science and technology change life, and innovation leads the future. Take mobile phones as an example, in the past, you had to find a phone booth to make a call, but now you can solve anything with a mobile phone. When it comes to the country of technology cows, the first thing that may come to mind is the United States, after all, Silicon Valley is world-famous.
But in faraway Northern Europe, there is a country called Finland. Not only does it have magnificent natural scenery, but it also has five top technologies that the United States is proud of.
So what are these five technologies?
1. Flash smelting technology
Flash smelting is a particularly popular technology in the metallurgical industry, especially for the extraction of copper ore.
This technology was first conceived by the Finnish company Outokumpu and has been used in production since the mid-20th century. It has completely changed the old-fashioned copper smelting method and brought great changes to the refining of copper ore.
In the past, copper smelting was mainly made by fire method, that is, the copper ore had to be ground into powder, and then heated at a very high temperature, and the copper was taken out of the ore through a series of chemical reactions.
However, this practice has many problems, such as low efficiency, low output, and easy to pollute the environment. The emergence of flash smelting technology solves these problems very well.
The biggest feature of this technology is that it is fast, fast and efficient. It uses a high-temperature, high-pressure method, which can be refined in a very short time.
The reaction time is so fast that it only takes a few seconds to get the copper out, compared to the traditional pyrotechnic copper smelting that takes hours, sometimes days.
So this new technology not only improves efficiency, increases output, but also greatly reduces environmental pollution.
Because under the conditions of high temperature and high pressure, the harmful substances in the copper ore can be fully decomposed and removed, so that the exhaust gas and wastewater emitted are much less. This has great benefits for both the environment and the protection of our health.
Because this technology is so easy to use and environmentally friendly, it is now used all over the world. More than half of the world's copper is now produced using Finland's flash smelting technology.
This technology has become the standard method of modern copper smelting, bringing a lot of money to copper producers and playing a good role in environmental protection.
The United States is a leader in many industrial technologies, but in the matter of copper smelting, Finland's innovative technology makes the United States a little unable to catch up.
2. Advanced icebreaker technology
Finland is located in the Arctic Circle and faces a problem for several months each year: the freezing of its seaports. This is not a trivial problem, as the frozen sea can cause a lot of trouble for the navigation of the ship.
But the Finns weren't stumped by the challenge, and instead developed the world's most advanced icebreaker technology.
Icebreakers, as the name suggests, are ships used to break ice and open the way. The design and construction of this type of boat is very different from that of ordinary boats.
The hull is particularly robust and able to withstand enormous pressures. The power system is also very powerful, capable of driving the hull forward on the ice, crushing or pushing the ice away. Finland's icebreaker technology has evolved and improved in response to this demand.
Finland's icebreakers can be said to be "giants" in the ice sea. Being able to easily cut a passage through the ice, no matter how thick the ice, will not stop these icebreakers from moving forward.
This is very important for Finland because with these icebreakers, their seaports can be kept open and ships can come and go normally, which is very important for the economy and people's lives.
Moreover, Finland's icebreakers are not only for their own country, because Finland's icebreakers are very advanced, many other countries also buy icebreakers from Finland for polar scientific research and resource development.
Although the United States also has icebreakers, Finland has an absolute advantage in terms of technology and numbers. American icebreakers are mainly used for polar expeditions and some specific tasks, and in terms of the number and technology of icebreakers, they are inferior to Finland.
This also makes the United States have to admit that Finland is indeed one step ahead in icebreaker technology.
3. Early screening and treatment of cancer
Cancer is a heavy topic in the eyes of many people, but in some places, such as Finland, it is different. They do a particularly good job in early screening and treatment of cancer, which gives more hope to many patients who have cancer.
Cancer screening is the process of using tests, such as blood tests, imaging tests, etc., to find out those cancer patients who may not have symptoms yet.
Finland has a well-developed screening system that detects cancer early, which makes it easier to treat and has a higher survival rate.
By detecting cancer early, doctors can prescribe the most appropriate treatment plan based on the type and condition of the cancer.
Doctors in Finland have many advanced methods in cancer treatment, such as targeted therapy and immunotherapy, which are new achievements in medical research in recent years.
In addition to the advanced treatment methods, the quality of medical care in Finland is also very high. Their healthcare system focuses on the holistic care of the patient, focusing not only on the treatment of the condition, but also on the patient's psychological state and quality of life.
This kind of all-round care allows cancer patients to receive good psychological support and quality of life while receiving treatment.
The U.S. is strong in medical technology overall, but Finland is doing better when it comes to cancer control. Finland is doing a good job in biomedical research, and its cancer understanding and treatment technology are at the world's leading level.
Finland invests heavily in public health, emphasizing prevention and reducing the incidence of cancer through various health education activities.
Finland's achievements in early cancer screening and treatment are comprehensive, with advanced medical technology, a well-developed screening system, high-quality medical services, and strong local support.
The combination of these factors results in a very high five-year survival rate for cancer patients in Finland, which is commendable globally. It also provides a good example for other countries to see the hope of cancer prevention and control.
4. Linux operating system
The Linux operating system is a household name in the computer industry. The founder, Linus Tovaz, is a software engineer from Finland.
His contribution was not only to create Linux, but also to advance the entire open source software movement. The Linux operating system is a system built on the Linux kernel, and the biggest feature is that it is free and open source.
So what is open source? In simple terms, the source code of software can be accessed by the public, and anyone can view, modify, and distribute the code.
This open nature has allowed the Linux operating system to be widely supported and participated by developers around the world.
Developers can customize and optimize Linux according to their own needs, and this kind of freedom and flexibility is not comparable to many commercial operating systems.
The stability and efficiency of the Linux operating system are also important reasons for its popularity, and there are very few crashes or failures, which is very important for servers that need to run for a long time.
At the same time, it occupies relatively little resources, and can run smoothly on various hardware configurations, especially some old hardware devices, Linux can give full play to their performance.
Security is also a major selling point of the Linux operating system, the source code is public, developers from all over the world can participate in the security review of the system, and any potential security issues can be found and fixed in time.
This open and transparent security mechanism makes Linux more indestructible in the face of various cyber attacks.
The Linux operating system has a wide range of applications, and according to statistics, more than 90% of the world's supercomputers are running Linux systems. These supercomputers play an important role in scientific research, weather forecasting, big data analysis, and more.
Although there are two major commercial operating system giants in the United States, Windows and macOS, Linux has become an irreplaceable existence due to its open source characteristics and the participation of developers from all over the world.
Linux's success is not only a source of pride for Finland, but also a triumph for the global open source community. We see the power of openness and collaboration.
Fifth, elevator technology innovation
We use elevators almost every day, although it looks simple, but in fact, the technology behind it is very high. When it comes to elevator technology, we have to mention the Finnish KONE Group, which is a leading company in the global elevator industry.
KONE's design, manufacturing and service capabilities provide efficient, safe and comfortable solutions for high-rise buildings, shopping malls, public transportation stations and more around the world.
Their elevators are fast and are able to get people from one floor to a very high floor in a short period of time. It is very important for office workers in skyscrapers to save a lot of waiting time.
Energy consumption is also low during operation, thanks to their high-efficiency motors and optimized control systems. The energy-efficient design not only reduces operating costs, but also benefits the environment.
In addition to high speed and low energy consumption, the intelligence aspect is also very good. It can automatically detect the number of passengers and floor selection, intelligently allocate elevator resources, and reduce waiting time. Predict peak hours through data analysis, automatically adjust operation strategies, and improve transportation efficiency.
Their elevators use a lot of eco-friendly materials, and they also minimize the environmental impact in the manufacturing process. Energy-efficient LED lighting and smart air conditioning systems are used to reduce energy consumption and carbon emissions.
Although there are many well-known elevator manufacturers in the United States, in terms of global market share, technological innovation and brand influence, Finland's KONE Group is clearly superior.
KONE's elevator technology has been widely recognized around the world and has become a benchmark in the elevator industry.
epilogue
Finland, a small Nordic country, is unremarkable, but its ability to innovate in science and technology has impressed the world.
This shows that whether a country can become a scientific and technological power does not depend on how big the place is, how many people there are, or how much money it has.
The key is to see if we can keep innovating, have the courage to break the mold, and turn high-tech things into really useful things.
