This is the real speech delivered by the genius Albert Einstein in Japan.

the year is 1922 Albert Einstein is in Japan far from the Grandeur of the Nobel Prize ceremonies happening in Stockholm he's been awarded the Nobel Prize for physics but he's not there to receive it instead he's in the Land of the Rising Sun honoring a commitment he made before the Nobel announcement in the hallowed Halls of Kyoto University a harush Falls over the crowd of eager students and faculty members they are about to hear from the man who has revolutionized their understanding of the universe the air is thick with anticipation Einstein stands at the podium ready to deliver a speech that will go down in history the title how I created the theory of relativity there are no written notes no prepared script just Einstein His Brilliant mind and an audience hungry for knowledge this account a firsthand narration of Einstein's Journey continues to Captivate and Inspire physicists and historians alike it's a testament Einstein's genius and his enduring Legacy in the world of science this is story behind the greatest revolution in physics it is not easy to talk about how I reached the idea of the theory of relativity there were so many hidden complexities to motivate my thought and the impact of each thought was different at different stages in the development of the idea I will not mention them all here nor will I count the papers I have written on this subject instead I will brief describe the development of my thought directly connected with this problem it was more than 17 years ago that I had the idea of developing the theory of relativity for the first time while I cannot say exactly where that thought came from I am certain that it was contained in the problem of the optical properties of moving bodies light propagates through the Sea of ether in which the Earth is moving in other words The Ether is moving with respect to the earth I tried to find clear experimental evidence for the flow of The Ether in the literature of physics but in vain then I myself wanted to verify the flow of The Ether with respect to the Earth or in other words the motion of the earth when I first thought about this problem I did not doubt the existence of The Ether or the motion of the earth through it I thought of the following experiment using two thermocouples set up mirrors so that the light from a single source is to be reflected in two different directions one parallel to the motion of the Earth and the other anti parallel if we assume that there is an energy difference between the two reflected beams we can measure the difference in the generated heat using two thermocouples although the idea of this experiment is very similar to that of Michaelson I did not put this experiment to the test while I was thinking of this problem in my student years I came to know the strange result of Michaelson's experiment soon I came to the conclusion that our idea about the motion of the Earth was with respect to the ether is incorrect if we admit Michaelson's null result as a fact this was the first path that led me to the special theory of relativity since then I have come to believe that the motion of the earth cannot be detected by any Optical experiment though the Earth is revolving around the Sun I had a chance to read Lawrence's monograph of 1895 he discussed and solved completely the problem of electrodynamics within the first order of approximation namely neglecting terms of order higher than V by C where V is the velocity of a moving body and C is the velocity of light then I tried to discuss the fizo experiment on the assumption that the lawence equations for electrons should hold in the frame of reference of the moving body as well as in the frame of reference of the vacuum as originally discussed by Lawrence at that time I firmly believed that the electrodynamic equations of Maxwell and Lawrence were correct furthermore the assumption that these equations should hold in the reference frame of the moving body leads to the concept of the invariance of the velocity of light which however contradicts the addition rule of velocities used in mechanics why do these two concepts contradict each other I realized that this difficulty was really hard to resolve I spent almost a year in vain trying to modify the idea of Lawrence in the hope of resolving this problem by chance a friend of mine in Burn Michelle besso helped me out it was a beautiful day when I visited him with this problem I started the conversation with him in the following way recently I have been working on a difficult problem today I come here to battle against the problem with you we discussed every aspect of this problem then suddenly I understood where the key to this problem lay the next day I came back to him again and said to him without even saying hello thank you I've completely solved the problem an analysis of the concept cep of time was my solution time cannot be absolutely defined and there is an Inseparable relation between time and Signal velocity with this New Concept I could resolve all the difficulties completely for the first time within 5 weeks the special theory of relativity was completed I did not doubt that the new theory was reasonable from a philosophical point of view I also found that the new theory was in agreement with Mark's argument contrary to the case of the general theory of rela ity in which Mark's argument was incorporated into the theory Mark's analysis had only indirect implications in the special theory of relativity this is the way the special theory of relativity was created my first thought on the general theory of relativity was conceived 2 years later in 1907 the idea occurred suddenly I was dissatisfied with the special theory of relativity since the theory was restricted to frames of reference moving with constant velocity relative to each other and could not be applied to the general motion of a reference frame I struggled to remove this restriction and wanted to formulate the problem in the general case in 1907 johannna Stark asked me to write a monograph on the special theory of relativity in the journal juk de Radio activat while I was writing this I came to realize that all the natural laws except the law of gravity could be discussed within the framework of the special theory of relativity I wanted to find out the reason for this but I could not attain this goal easily the most unsatisfactory point was the following although the relationship between inertia and energy was explicitly given by the special theory of relativity the relationship between inertia and weight or the energy of the gravitational field was not clearly elucidated I felt that this problem could not be resolved within the framework of the special theory of relativity the Breakthrough came suddenly one day I was sitting on a chair in my patent office in Burn suddenly a thought struck me if the accelerated frame of reference we need a new gravitational field I could not solve this problem completely at that time it took me eight more years until I finally obtained the complete solution during these years I obtained partial answers to this problem anst Mark was a person who insisted on the idea that systems that have acceleration with respect to each other are equivalent this idea contradicts ukian geometry since in a frame of reference with acceleration ukian geometry cannot be applied describing the physical laws without reference to Geometry is similar to describing our thoughts without words we need words in order to express ourselves what should we look for to describe our problem this problem wasn't solved until 1912 when I hit upon the idea that the surface theory of Cole Friedrich gaus might be the key to this mystery I found found that gaus surface coordinates were very meaningful for understanding this problem until then I did not know that burnhard rean who was a student of gaus had discussed the foundation of geometry deeply I happened to remember the lecture on Geometry in my student years in Zurich by Cole Friedrich giser who discussed the gaus theory I found that the foundations of geometry had deep physical meaning in this problem when I came back to Zurich from Prague my friend the mathematician Marcel Gman was waiting for me he had helped me before by supplying me with mathematical literature when I was working at the patent office in burn and had some difficulties in obtaining mathematical articles first he taught me the work of kastro Gregorio RI and later the work of reman I discussed with him whether the problem could be solved using rean Theory or in other words by using the concept of the invariance of line elements we wrote a paper on this subject in 1913 although we could not obtain the correct equations for Gravity I studied Ran's equations further only to find many reasons why the desired results could not be attained in this way after 2 years of struggle I found that I had made mistakes in my calculations I went back to the original equation using invariance Theory and tried to construct the correct equations in 2 weeks the correct equations appeared in front of me concerning my work after 1915 I would like to mention only the problem of cosmology this problem is related to the geometry of the universe and to time the foundation of this problem comes from the boundary conditions of the general theory of relativity and the discussion of the problem of inertia by Mark although I did not exactly understand Mark's idea about inertia his influence on my fault was enormous I solved the problem of cosmology by imposing invariance on the boundary condition for the gravitational equations I finally eliminated the boundary by considering the universe to be a closed system as a result inertia emerges as a property of interacting matter and it should vanish if there were no other matter to interact with I believe that with this result the general theory of relativity can be satisfactorily understood epistemologically this is a short historical survey of my thoughts on creating the theory of relativity this is the end of Einstein's remarkable journey in creating the theory of relativity his story serves as a powerful reminder of the boundless potential of curiosity and persistence in the pursuit of knowledge as Einstein famously said the important thing is not to stop questioning so let us heed his words and continue to explore the mysteries of the universe with un yielding [Music] [Applause] curiosity
