The distance between two fixed points will never change and always scalar in its direction!The title of the thread may not look new and the simple logic is the very basic principle in the elements of Geometry for a beginner in schools. But the essence of the various formulae we learnt from Mathematics, Physics or Chemistry will have an impact in our life lessons too. Unfortunately, many of us happen to learn it from the younger generation as we tend to lose our cool or lack of will to display maturity in our Social behaviour.
The famous Newton's third law of Motion - "Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first." which explains the relationship between a physical object and the forces acting upon it. In simple words, every action will have an equal opposite reaction!
Let us take Chemistry where the role of Chemical reactions are vital. Here too a typical word - 'catalyst' changes the dynamics of a Chemical reaction without losing its original form. When two or more Organics are participating to form a new mixture, a Catalyst is used to accelerate the Chemical reaction without getting changed it original form after the process is over. That means the best way is to be neutral always and help out in settling the scores among the parties involved.
Finally, our thread tile refers to a distance between two points A and B. It would always be the same from A or even measured from B. Either A or B are not great. In Public forums or in our close relations, we often forget this and throw words against people dragging them into controversies. Nothing will happen to the other end but it exposes our nature and drag ourselves into unwarranted controversies. Isn't it?
