⚔️🔬 Science 🔬⚔️ The importance of science is well known today. Science is not just limited branch, it is very wide branch and extend study of the basics of science makes a new branch of science. For example, Biology is branch in which the study of living being occurred, Chemistry the study of chemical, Microbiology the study of microorganisms, cell biology the study of all types of cell....etc....etc. But science does not seem to be as important as it should be. Now people understand that there is no alternative without science. Every one know that the science is a great career field, this is also a good education field, that's all there is to it. Still, we can say that ' Science is the one of the army of our country '. What is this nonsense....... How is that........ So let to prove this sentence, with evidence.... At first I would like to say that, we can't imagine the world without Science, because Science has given us so much
Basic and Important term of Physics
Measurements
Physics is a basic discipline in the category of Natural Science which also includes other disciplines like Chemistry and Biology .
In Physics , we attempt to explain diverse physical phenomenon in term of few concepts and laws.
Basically there are two domain in the scope of Physics : Macroscopic and Microscopic.
The Macroscopic includes phenomena at the laboratory, terrestrial and astronomical scales.
The macroscopic phenomena deals mainly with the branch of classical mechanics which includes subject like mechanics , electrodynamics, optics and thermodynamics.
The Microscopic domain includes atomic, molecular, and nuclear phenomena.
The microscopic domain of physics deals with the constitution and structure of matter at the minute scale of atoms and nuclei and their interactions with electrons, photons and other elementary particles.
The scope of physics is truly vast. It covered a tremendous range of physical quantities like length , mass, time , energy, .......Etc .
Most important term of the physics is measurements.
We can't imagine the world without and measurement units. Ancient people use measurements but it's not universal, because it's changes with changing place and environment. Measurements units we need because, in every day life every time we weight of some thing, we measure something and various measurements are used by us. For every day we must have to know scientific research and and information related to the measurement.

Measurement :
experiment and measurements form the basis of physics. Hence there is definite need for measurements in physics.
Units for Measurements :
The reference standard used for the measurement of a physical quantity is called a Unit.
Properties of good Unit :
- Unit should be easily available.
- It should be invariable.
- It should be universally accepted.
- It should be reproducible.
- It should not perishable.
System of Units :
Units are classified into two groups, fundamental units and derived units.
"A set of fundamental units and derived units is called a System of units."
"A set of fundamental units and derived units is called a System of units."
