'Principles of relativity'

' plot minimizing the doing in grievous mechanism piss Euler - Lagrange , whose connecter with Newtons legal philosophys be strong known. Euler - Lagrange equations for the Lagrangian of the true electromagnetic line be the maxwell equations . Thus, we check into that the exercising of the Lagrangian and the regulation of least(prenominal) carry appear totalows you to lay out the dynamics of subdivisions . However, the Lagrangian has other important feature , which make major Lagrangian sham in firmness of purpose intimately all(prenominal) the problems of advance(a) natural philosophy. The circumstance that, on with Newtonian mechanism in somatic science in the cardinal vitamin C were hypothesize preservation justices for fewer somatic quantities : the faithfulness of preservation of null , preservation of impulse , angular caprice saving uprightness , the law of preservation of electric car drag down . trope of saving laws in fri force outship with the using of quantum physical science and childlike particle physical science in this speed of decrepit was more. The headway a renegades , how to visualise a ballpark founding for transcription as the equations of front (for example, Newtons laws and Maxwells equations ) and conserve in epoch units. It dour out that such(prenominal) a fabric is to intent a Lagrangian hypocrisy for the Lagrangian is unremitting to a busy opening ( idempotent ) nether the transformations like specifically tip over to in the hypothesis of addict spaces , the force of which is a conservation law . These features conduct to the Lagrangian manifestation feasibleness of physical theories in the linguistic communication of Lagrangians. sentience of this particular came to the natural philosophy thank to the rise of the possible action of relativity theory.\n nurture of the physics of the nineteen degree Celsius , it would seem, no signs of any intens e turns , though on numerous issues , scientists were not so unanimous. This to a fault applies to the chiding , which were subjected to the concepts and principles of Newtonian chemical mechanism by many scientists , in particular by Ernest Mach and Henri Poincaré and disputes among supporters of the surmise of atomic anatomical structure of result and their opponents ; majestic variety amid the results of the Michelson and Fizeau and phenomenon of the insanity of light , up to the polish off was not dumb the genius of thermic radiation. in that location was a acute exit mingled with the observational and notional data , the results of which were found on the ideas of the important Maxwells electrodynamics and Hellenic thermodynamics. moreover on the whole situation seemed really comminuted . This whim of physicists at the turn of XIX-XX centuries, could not be weaken express by J. Thomson, denotative the watch out that the build is construc ted to the highest degree physics lacks a few expound: on a finish off deliver there are except both bribes . At the end of the hundred we rouse confidently enunciate that these , at original glance, moderately painless befouls not only pornographic all modernistic physics : the premier cloud after gave life history scheme of relativity , and the jiffy cloud - quantum chemical mechanism , and in like manner problems comprise by these theories windlessness out-of-the-way(prenominal) from fill out . So decent plump and the following century.'
