Scope And Excitement Of Physics

The domain of physics consists of wide variety and large number of natural phenomena. Hence, the scope of physics is very vast and obviously the excitement that one gets from the careful study of physics has got no boundaries.

Scope of Physics

For example, when we study one of the basic physical quantities called mass, we come across the values ranging from minute masses like mass of an electron (of the order of 10−30 kg) to heavy masses like mass of universe (1055 kg). Similarly, in case of other basic quantities like length and time also the range is very wide.

Hence, the scope of physics can be understood easily, only when we can classify the study of physics chiefly into three levels. They are

(a) Macroscopic level study of physics.

(b) Mesoscopic level study of physics.

(c) Microscopic level study of physics.

Macroscopic level study of physics: Macroscopic level study of physics mainly includes the study of basic laws of nature and several natural phenomena like gravitational force of attraction between any two bodies in the universe (in mechanics), variation of quantities like pressure, volume, temperature, etc. of gases on their thermal expansion or contraction (in thermodynamics), etc.

Microscopic level study of physics: The microscopic level study of physics deals with constitution and structure of matter at the level of atoms or nuclei. For example, in case of nucleus interaction between elementary particles like electrons, protons and other particles , and in the case of materials point of view particle size and structure. Since the bulk properties of the material is different from the microscopic level properties. .

Mesoscopic level study of physics: The mesoscopic level study of physics deals with the intermediate domain of macroscopic and microscopic, where we study various physical phenomena of atoms in bulk.

So, the edifice of physics is beautiful and one can appreciate the subject as and when one pursues the same seriously.

Excitement of Physics

The study of physics is exciting in many ways as it explains us the reason behind several interesting features like (a) how days and nights are formed? (b) how different climatic conditions are formed in different seasons? (c) how satellite works and helps in using several devices like television, telephones, etc.? (d) how an astronaut travels to celestial space ? (e) how we can convert one form of energy to another ? (f) how different types of forces are governing different types of motion in universe ? (g) how different type of materials are used in the present day-SMART science technology?

It is quite common and simple that every human being on the earth will be interested to know the answers for at least few of the above questions. As physics is the subject which answers them, naturally the study of physics will be exciting.
