Physical phenomena are the world around us
The world is diverse - no matter how trite it may besaying, but it really is. Everything that happens in the world is under the close attention of scientists. Something they have long known, something to be learned. A person, a curious creature, always tried to know the surrounding world and the changes taking place in it. Such changes in the surrounding world are called "physical phenomena". These can include rain, wind, lightning, rainbow, other similar natural effects.
Changes in the surrounding world are numerous and diverse. Curious people could not stay away without trying to find an answer to the question of what caused such interesting physical phenomena.
It all started with the monitoring processthe surrounding world, which led to the accumulation of data. But even a simple observation of nature caused certain reflections. Many physical phenomena, while remaining unchanged, manifested themselves in different ways. For example: the sun rises at different times, from the sky is then rain, then snow, an abandoned stick flies that far, then close. Why is this happening?
The appearance of such questions becomesevidence of the gradual development of the perception of the world by man, the transition from contemplative observation to active study of the environment. It is clear that every active phenomenon that is changing and manifested in a different physical way only accelerates. As a result, attempts have been made to experimentally learn about nature.
The first experiments looked very simple,for example: if a stick is thrown so, it will fly far away? And if you throw the stick in a different way? This is already an experimental study of the behavior of a physical body in flight, a step towards establishing a quantitative connection between it and the conditions causing this flight.
Of course, everything said is very simplistic anda primitive account of attempts to study the world around him. But, in any case, even in a primitive form, but it makes it possible to consider the physical phenomena that take place the basis for the emergence and development of science.
In this case, it does not matter which onethis is science. At the heart of any process of cognition is the observation of what is happening, the accumulation of initial data. Let it be physics with its study of the surrounding world, let it be biology, cognizing nature, astronomy, trying to know the Universe - in any case, the process will be the same.
The physical phenomena themselves can be different. To be more precise, their nature will be different: the rain is caused by one reason, the rainbow by others, the lightning by the third. Only to understand this fact took a very long time in the history of human civilization.
The study of various phenomena of nature and itslaws are engaged in such a science as physics. It was she who established a quantitative connection between the various properties of objects or, as physicists say, bodies, and the essence of these phenomena.
During the study, specialtools, research methods, units of measurement, allowing to describe what is happening. Knowledge of the surrounding world expanded, the results led to new discoveries, new tasks were put forward. There was a gradual isolation of new specialties dealing with specific application problems. So began to appear heat engineering, the science of electricity, optics and many, many other fields of knowledge within physics itself - not to mention the fact that other sciences, dealing with very different problems, also appeared. But in any case, it must be recognized that observation and study of the phenomena of the surrounding world has allowed the formation in the course of time of numerous new branches of knowledge that contributed to the development of civilization.
As a result, a whole system of studying and mastering the world, the surrounding nature and man himself - from simple observation of physical phenomena.
The present material describes physical phenomenaas a basis for the formation and formation of science, in particular, physics. An idea is given of how the development of science took place, such stages as the observation of what is happening, the experimental verification of facts and conclusions, and the formulation of laws are considered.
