Measurement is a technique in which the properties of an object are determined by comparing them to a standard quantity. In addition, measurement is the essential metric to express any quantity of objects, things and events.
Introduction of physics;
At the present time, there are three main frontiers of fundamental science.
i) World of extremely large
First the world of extremely large, the universe itself, Radio telescope now gather information from the far side of the universe and have recently detected, as radio waves, the “ fire Light” of the big bang which probably started off the expending universe nearly 20 billion year ago.
ii) World of extremely small
Second, the world of the extremely small, that of the particles such as, electron, protrons,neutrons, mesons and others.
iii) World of complex matter
The third frontiers is the world of complex matter. It is also the world of middle-sized things from molecules at one extreme to the Earth at the other.
Definition of Physics;
“Physics deal with the study of matter and energy and the relationship between them”
the study of physics involves investigating things as the law of motion, the structure of space and time, the nature and type of forces that hold different materials togather, the interaction between different particles, the interaction of electromagnetic radition with matter and so on.
Branches of Physics;
By the end of 19th century many physicists start believing that every thing about the physics has been discovered. However, about the beginning of the twentieth century many new experimental facts revealed that the laws formulated by the previous investigators neeed modifications. Further researches gave birth too many disciplines in physics such as.
Nuclear Physics:
it deal with atomic nuclei
Particle Physics:
it is concerned with the ultimate particles of which the matter is composed.
Relativistic mechanics:
it deal with velocities approaching that of light.
