Most of us almost all our life lived in the XX century. What is so different about this period from those that were there before? The one thing that makes this era the most unique is the rapid development of science and technology. A list of the major achievements of the century includes space exploration, antibiotics, the computer and the Internet, genetic engineering, operative treatment and many others. All this became possible thanks to the incredible growth of the volume of accumulated human knowledge about the Universe.
Speaking of scientific advances, people are generally interested in the practical benefits, for example, higher living standards. But there is another dimension of science. Improving our quality of life, it also opens a magnificent window into the Universe. It shows us that the whole world around us exists according to general rules and principles and these rules can be detected using scientific methods. Having been tested and checked carefully, the rules are raised to the rank of "laws of nature" which make up the intellectual structure in which there is a place for any phenomenon in the Universe.
What are the main stages of knowledge acquisition? What do we need to understand the nature of science? Scientists believe that there is no complete or absolute truth, there are mostly more-or-less accurate judgments that can be made in relation to the world and how it operates. The appearance of judgments and the resulting knowledge is preceded by such provisions that science is tentative. The way to knowledge acquisition supposes such steps as observation and experiment, putting forward hypotheses, identifying patterns, creating theories, prediction and return to the experiment to check the veracity of what was predicted.
Scientists are constantly working on the advancement of science. The development of science obeys its own logic and depends on the emergence of new tools and ideas. Sometimes progress moves in leaps and bounds, and sometimes it suddenly slows down. In some cases discoveries in one area deeply affect others, giving them new tools. With each new turn of the cycle, the theory is becoming more precise and our view of nature is getting fuller. We can also assume that we are dealing with a never-ending process. As it is impossible to reach the end of the circle, it is impossible to obtain from nature the final confirmation of ideas. This means that there is always the room for new ideas and expanding the horizons of knowledge in new directions.
