The nature is very colourful and diverse.We observe many phenomenon in our daily life. Falling of apples from tree towards ground, water flowing from highlevel to lowlevel, formation of rainbow and many more.
Physics is an attempt to study these phenomenon and understand them. According to famous scientist DR Fenyman, physics is “Understanding Nature”.All the phenomenon takes place according to some rules of the nature. These rules can be termed as the basic laws of nature. These rules can be understood by observing the complete phenomenon.
The observation of the phenomenon can be compared to watching a game. One can understand the rules of the game by completey watching the game.In a similar fashion,a particular phenomenon can be understood by watching it completely.One can try to understand the rules of nature by completely watching the phenomenon.If the phenomenon is not observed completely, one may end with partial results and hence he laws observed by him will be invalid, hence a systematic and completele observation of the phenomenon is required. Is it possible to make laws by each and everyone if they observe phenomenon? The answer to to this question is as simple as this. We all know the rules of the football but each and everyone cannot become professional players.Only one with vast experience only can become a professional player. On the other hand, only one who has made dedicated observation of the phenomenon for years can guess laws pertaining to it and hence explaining the phenomenon successfully. These people those who are dedicated to observe the phenomenon, explain and apply them are called as SCIENTISTS.
No one is authorised to frame laws in physics, scientists just discover these rules and explain it. If a law or fact cannot or can partially explain the phenomenon, then the law is invalid and the theory collapses. The law that can completely explain , in the sense that the proposed theory and practically observed facts are in agreement, then the law is said to be valid. Some of the examples of valid laws are: -
1) Newton’s law of motion and Gravitation, which deals with macroscopic objects and heavenly bodies, applicable to microscopic objects to some extent.
2) Galileo’s laws of planetary motion, which describes the type of motion, period of revolutionof planets around the sun.
3) Planck’s law explains quantum observations.
If a new movement is observed and if the successful theories so far cannot explain the observation, then the law can be modified or considerd as invalid.The law which can explain the new observation will be considerd as a valid law.Very good examples for this is plum pudding model, failure of Newton’s laws to quantum mechanics etc.
Hence the laws of nature cannot be understood so clearly, it has taken hundreds of years to understand only a part of it due to the cloud of complexity over it.Therefore continuous attempt is made by the scientists to understand “Laws of Nature”.
