TheBasicsofSpecialRelativityandItsImplicationsinModernPhysics

ThePrincipleofRelativity

SpecialrelativityisatheoryformulatedbyAlbertEinsteinin1905.Itdealswiththephenomenaobservedbyobserversmovingatrelativespeedsnearthespeedoflight.Thetheoryisbasedontwomainpostulates:theprincipleofrelativityandtheconstancyofthespeedoflightinallinertialreferenceframes. Theprincipleofrelativitystatesthatthelawsofphysicsarethesameforallinertialobservers,regardlessoftheirrelativemotion.Thismeansthatthereisnoabsoluterestframe,andallmotionisrelative.Inotherwords,anobservercannotdeterminewhethertheyareatrestormoving,asthereisnopreferredframeofreference.
