What Is Physics, What Does It Mean?

The science of material phenomena other than chemical changes. The word physics, which is used with various spellings in many languages, is derived from the root bheu, which expresses the meanings of being and breeding in the Indo-European language group. The Greek word phusis, which derives from this root, expresses the meaning of nature. Ancient Greek philosophy, in its first period, was a physics-nature (Yu. Phusis) philosophy. The first Greek thinkers were physicists, not philosophers or philosophers in the classical sense (natural scientist N). As a matter of fact, Miletus philosophy is also called Miletus physics. The early Greeks found man’s superiority in his technical labor.

For example, according to Anaxagoras, man is the wisest of animals because he has hands.

Thales was a groundbreaking astronomer in his era; According to Herodotus, he had informed the Ionians that there would be a solar eclipse of 28.5,585 days.

Anaximander was observing the storms of the land and sea, trying to explain the universal order with these, which he used for the first time for the unity of the world, with the word cosmos. He also wrote the physics work On Nature.

Anaximenes was also a physicist in the current sense of the word; he explained the formation of nature with the condensation and sparseness of the air, he gave the correct explanation of the lunar eclipse, he was the first in history to use the phrase standing stars. He also put forward an interesting theory of earthquakes.

At the end of this tradition of materialist-physical thinking, Aristotle agrees with the 20th century Einstein in the notion that where there is no object, time and space cannot exist.

The philosophy of the Stoics is also called stoic physics. The link between physics and philosophy, which had been broken by the intervention of metaphysics, was reconnected centuries later by the great masters of scientific philosophy, never to be broken again. Physics, which is a concrete natural science, has been interpreted ideally by falling into the trap of the abstract method of metaphysics. The reason for this is that contemporary physics overflows into the universe of infinitely large and infinitely small, out of the visible. However, the contemporary physicist tries many physical data that he has caught outside of the visible, by putting them into practice, and obtains practical results that can be seen from them. The technical application of scientific data on macrocosm and microcosm proves this at every moment. The physicist, who does not know dialectics, may overlook this connection of theoretical data with practice and say, like the famous and esteemed physicist Heisenberg, that “the elementary particle of physics is not a material formation in time and space, but just a simple symbol”. This shows that he did not know dialectics as well as classical philosophy, and on May 19, 1943, physicists and philosophers were asked in London, “What is the relationship between philosophy and physics?” This point was particularly pointed out in their controversial joint meeting on Professor S. Stebbing, who wrote a summary of this interesting meeting in the June 19, 1943 issue of Nature, says: “The answers of philosophers and physicists to this question do not always match.

For example, James Jeans says that it is the physicist’s job to decide whether materialism is right or wrong, since he considers metaphysics beyond just physics. However, since rejecting materialism counts as adopting idealism, it cannot be easily defended that the physicist can have the last word as a physicist. For the physicist must be a philosopher and be skilled in philosophical thought before he can have this last word. On the other hand, the physicist who will be involved in this subject must also be able to avoid the mistakes of previous philosophers, which were definitely rejected and refuted. Although, scientists can also think about big questions that have occupied philosophers for a long time, such as the place of man in the universe, the quality of things, spirit and matter, and the relationships between them. In fact, such great problems arose in the minds of some great poets. But the extent to which these great problems are problems can only be discussed at the last stage of philosophical development. However, physicists often tend to say more than they know by taking shortcuts.” He tells: “Isn’t it strange, physicists are starting to lose faith in science at a time when ordinary people are starting to believe in exact science.

In my youth, physicists believed that the laws of physics gave us a complete and true knowledge of the motions of bodies, and that the physical universe was really what the physicists had in their equations. Philosophers have been skeptical of this since the time of Berkeley. However, scientists did not care for philosophers, as their criticism did not dwell on the details of the scientific method. Now things have turned around. Where philosophy dictates, the language of physics stutters. breaking the laws of physics
