After Einstein discovered General Theory of Relativity in 1915, what major works did he make?

After Ein stein discovered the General Theory of Rel ativity in 1 9 1 5 , he continued to make significant contributions to the field of physics and mathematics . Some of his major works include : \n \n 1 . The Equ ival ence Princi ple : Ein stein ' s theory of general relativ ity is based on the equivalence principle , which states that the laws of physics are the same for all obser vers in uniform motion . This principle has been confirmed by numerous experiments , including the b ending of star light around massive objects and the precise measurement of the gravit ational red shift of light . \n 2 . The Cos m ological Constant : In 1 9 1 7 , Ein stein introduced the cosm ological constant , a term he added to his theory of general relativ ity to explain the uniform ity of the universe . The cosm ological constant is a constant force that acts in all directions and counter act s the gravit ational att raction between objects . \n 3 . The Theory of Gra v it ational W aves : In 1 9 1 6 , Ein stein predicted the existence of gravit ational waves , which are r ipp les in the fabric of spac etime caused by the acceleration of massive objects . Although gravit ational waves have not yet been directly detected , they are an important area of research in ast ro physics and cosm ology . \n 4 . The Princi ple of Equ ival ence : Ein stein ' s principle of equivalence states that the laws of physics are the same for all obser vers in uniform motion . This principle has been confirmed by numerous experiments , including the b ending of star light around massive objects and the precise measurement of the gravit ational red shift of light . \n 5 . The Theory of the Brown ian Mov ement : In 1 9 2 6 , Ein stein developed a theory of the Brown ian movement , which describes the random motion of particles susp ended in a fluid . This theory has been used to study a wide range of phen omena , including the motion of mole cules in liqu ids and the behavior of atoms in sol ids . \n \n Th ese are just a few of the many major works that Ein stein produced after the discovery of the General Theory of Rel ativity . His contributions to physics and mathematics continue to shape our understanding of the universe and insp ire new areas of research . </s>
