What Is Mass, What Does It Mean?July 2, 2021
A large piece made up of small pieces. In the social sense, it expresses the crowd of people and is characterized by the phrase heap. Metaphysicians and idealists have always underestimated the masses of the people and argued that history was determined by great men (i.e., elites, rulers, leaders, geniuses, important people). It is the doctrine of historical and dialectical materialism that analyzes and demonstrates that it is the masses of the people who make history.
On the contrary, in the natural sciences, metaphysicians and idealists who do not attach importance to mass in society cling to it in order to grasp the material. For them, things that have no mass (for example, the energy they think have no mass) are not material. They don’t know that like a stone, a ray of light also carries mass. After all, matter is a philosophical concept; just like apple, pear, quince etc. in nature. Apart from tangible assets such as stone, soil, light, etc., if there is no such thing as fruit. Apart from tangible beings such as such, there can be no such thing as matter. A cup of hot tea is heavier than the same cup of cold tea because a thermal mass has been added to it. It was the great physicist Albert Einstein who put forward and proved the mass-energy equivalence. (dir N.) In physics, mass is the ratio between the force applied to an object and the acceleration caused by this force. The Italian physicist Galileo demonstrated with his famous tower of Pisa experiment that objects of different weights fall to the ground at the same time. The British physicist Newton found the reason for this in the fact that the mass of the object thrown to the ground during motion cannot change. The mass always and everywhere remained unchanged. Whereas, Einstein proved that the mass of a moving body increases (changes) with its motion. Einstein’s discovery overthrew metaphysical physics, which advocated immutability, and revealed the reality of dialectical physics. Another philosophical significance of this discovery is that it demonstrates that energy, which metaphysics considers spiritual, has a mass, and that energy is also matter.
According to Einstein’s demonstration, the mass of a moving body increases due to the addition of the energy of that body, which increases with its motion. So energy also had mass. Einstein demonstrated with his famous formula E=mc² that the energy contained in any piece of matter is equal to the mass of that object multiplied by the square of the speed of light. In this formula, the letter E denotes energy, m denotes mass, and c denotes the speed of light. This means that even if a mobile object can reach the speed of light, its mass will be infinite (?N.) (the object will lose its mass and its mass will be equal to the speed of light and its mass. Also, since the speed of light is not infinite, its mass will not be infinite anyway. N.). This simple reasoning also clarifies the reason for the infinity of the universe (?N.) If matter throws its mass and travels at the speed of light, we call it energy, and in Turkish, energy. If the opposite happens and the energy becomes massive, we call it matter, and in Turkish, matter. Since 1945, these have been easily interchanged in the physics laboratory.
