Difference Between Leptons and Hadrons
Leptons vs Hadrons It has been our understanding for over three hundred years that matter consists of atoms. Atoms are thought to be indivisible until the 20th century. But the 20th century physicist discovered that the atom can be broken into smaller pieces, and all the atoms are made of different compositions of these […]
Difference Between Local and Global Maximum
Local vs Global Maximum The greatest value of a set or a function is known as maximum. Consider the set {ai | i ∈ N}. The element ak where ak ≥ ai for all i is known as the maximum element of the set. If the set is ordered it becomes the last element of […]
Difference Between Maximum and Maximal
Maximum vs Maximal It is often required by humans to denote the boundaries of things. If something cannot exceed beyond a certain limit, it is called maximum in the common sense. However, in the mathematical usage a much more rigorous definition has to be provided to prevent ambiguities. Maximum The greatest value of a […]

Difference Between Moment and Couple
Moment vs Couple Moment of force and couple are two important concepts found in mechanics. These describe the effect and cause of rotation in force systems, particle systems, and in rigid bodies. Moment of a force governs many of the rotational properties of the systems. From a certain perspective, it is the equivalent of […]
