Physics development: The word physics is derived from the Greek word fascia, which means “nature”.In this, nature and philosophies are studied and modern physics definition, energy, matter, and the relationship between them are studied.
Physics is the study of the interconnection of liquids and energy and the study of the final structure of liquids.
Physics is the branch of natural science under which things related to motion, gravity, energy, time, etc. are studied. It mainly has two branches:
Two parts of Physics:
- Classical Physics
- Modern Physics
The main subheadings are as follows:
It mainly studies the physics of the twentieth century. Its main subheadings are as follows:
On the one hand, physics has given all kinds of physical comforts to human beings, on the other hand, the physics world has successfully helped many people to understand many philosophical aspects of life by successfully explaining many mysteries.
History of the development of physics
The history of physics begins with the existence of human life on Earth. primarily, the man was like an animal. Humans took inspiration to create fire by looking at the sparks caused by rubbing stones with stones. Gradually, humans started making weapons with stones and used these weapons for hunting. This era came to be known as the Stone Age called the Stone Age.
Six thousand years ago, humans discovered copper and got knowledge about metal and in this age, they made tools, household items, wheels, etc. made of copper and bronze (metals).
Scientists based physics on the basis of many pieces of evidence and hypotheses since the time when man came to Earth. Therefore, the development of physics was divide into three parts. so, Three parts are as follows:
Ancient era (1500-1780 AD): In this era, various branches of science developed on an experimental basis. In the same era, the sparking of stones led to the knowledge of heat energy. The knowledge of sound produced due to the collision of objects and the knowledge of the weight of objects on lifting objects was realized. The main research of this era – the steam engine by James Watt, the laws of gravity and motion by Newton, the microscope by Galileo, the knowledge of the laws of gases by Biel, the information of the laws of electricity by Ampere presented to the world.
Medieval era (1780–1900 AD): This era saw significant inventions in the field of physics; Like the theory of human evolution, x rays, dynamo, electromagnetic waves, etc.
Present era (after 1900 AD): The present period is called the golden period of the progress of physics. Max plank gave the quantum theory in 1901. Einstein’s introduction of two important theories of mass-energy equation (E = mc ^ 2) and the theory of relativism in 1905 triggered a revolution in the field of physics.
In this era, electrons, neutrons, protons were discovered! Even today humans are engaged in many such exploratory works, in which one day will definitely get success. All these tasks are beyond the search of ordinary human beings.
