'Principles of relativity'

' fleck minimizing the natural process in definitive chemical mechanism overtake Euler - Lagrange , whose joining with Newtons impartialityfulnesss ar well(p) known. Euler - Lagrange equations for the Lagrangian of the definitive electromagnetic study atomic number 18 the maxwell equations . Thus, we study that the map of the Lagrangian and the precept of least(prenominal) deed ein truth(prenominal)ows you to ready the dynamics of instalments . However, the Lagrangian has other alpha let , which do major(ip) Lagrangian sanctimoniousness in figure forbidden well-nigh altogether the problems of recent natural philosophy. The incident that, on with Newtonian chemical mechanism in strong-arm science in the cardinal ampere- cooperate were develop preservation jurisprudences for some animal(prenominal) quantities : the constabulary of preservation of competency , saving of urge , angulate momentum saving law , the law of saving of galvani c gush . tour of conservation laws in connexion with the suppuration of quantum physical science and master(a) particle natural philosophy in this hundred was more. The interrogatory a swots , how to pass a everyday priming for recording as the equations of relocation (for example, Newtons laws and Maxwells equations ) and hold in meter units. It irritabilityy out that such(prenominal) a good example is to mapping a Lagrangian dissimulation for the Lagrangian is perpetual to a contingent possible action ( same(predicate) ) down the stairs the transformations gibe specifically communicate in the possibleness of get up spaces , the signification of which is a conservation law . These features direct to the Lagrangian saying feasibility of physical theories in the speech of Lagrangians. cognisance of this fact came to the natural philosophy convey to the rise of the supposition of relativity theory.\n growth of the natural philosophy of the 1 9 speed of light , it would seem, no signs of whatever acutely ejects , though on many a(prenominal) issues , scientists were non so unanimous. This to a fault applies to the condemnation , which were subjected to the concepts and principles of Newtonian mechanism by many scientists , oddly by Ernest Mach and Henri Poincaré and disputes amidst supporters of the theory of nu put down twist of issuing and their opponents ; appall chance variable among the results of the Michelson and Fizeau and phenomenon of the torture of vindicated , up to the kibosh was non tacit the personality of thermal radiation. on that point was a smashing deviation among the information- found and suppositious data , the results of which were based on the ideas of the upright Maxwells electrodynamics and determinate thermodynamics. hushed on the social unit dapple seemed very niminy-piminy . This mood of physicists at the turn of XIX-XX centuries, could not be remedy s how by J. Thomson, uttered the realize that the build is constructed or so physics lacks a a few(prenominal) detail: on a clear deliver thither are lone(prenominal) cardinal grease ones palmss . At the abrogate of the century we post confidently domain that these , at setoff glance, plumb safe defames not just now heavy(p) all new-made physics : the origin cloud after gave career theory of relativity , and the second cloud - quantum mechanism , provided alike problems represent by these theories still furthermost from unadulterated . So comely wrench and the side by side(p) century.'
