when does the solor eclipse start and end This occurs when the Sun, Moon and Earth are aligned and ends when they are not aligned what are its kinds? UNANSWERABLE how many times does it takes place in an year? Between two and five solar eclipses occur every year, with at least one per eclipse season. what was observed in this context during 1919? The observation of a total solar eclipse of May 29, 1919, helped to confirm Einstein's theory of general relativity. what is this last theory? General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time or four-dimensional spacetime. when was it stated? 1915 the person who stated this theorem; who was he? Albert Einstein

Albert Einstein [SEP] Introduction
The son of a salesman who later operated an electrochemical factory, Einstein was born in the German Empire, but moved to Switzerland in 1895 and renounced his German citizenship in 1896. Specializing in physics and mathematics, he received his academic teaching diploma from the Swiss Federal Polytechnic School () in Zürich in 1900. The following year, he acquired Swiss citizenship, which he kept for his entire life. After initially struggling to find work, from 1902 to 1909 he was employed as a patent examiner at the Swiss Patent Office in Bern. Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field.
