The Einstein Theory of Relativity

The Einstein Theory of Relativity
By Prof. H.A. Lorentz of the University of Leyden
Comments -
1.Already before the war, Einstein had immense fame among physicists, and among all who are interested in the philosophy of science, because of his principal of relativity.
2.In orthodox Newtonian dynamics the principal of relativity had a simpler form, which did not require the substitution of local time for general time.
3.Einstein's extension of his principle so as to account for gravitation was made during the war, and for a considerable period our astronomers were unable to become acquainted with it, owing to the difficulty of obtaining German printed matter.
4.The immense unification effected by electro-magnetism apparently left gravitation out of its scope.
5.Einstein supposes that space is Euclidean where it is sufficiently remote from matter, but that the presence of matter causes it to become slightly non-Euclidean - the more matter there is in the neighborhood, the more space will depart from the Euclid.
questions -
1.What is the difference between local and general time?
2.Was Einstein in Germany throughout the war?
3. Was Einstein living in Germany during both wars?
4.What exactly is a Euclid?
What part did gravity play in his theory of relativity?
vocabulary-
1.intervened-to come between disputing people, groups, etc.; intercede; mediate.
2.immense-immeasurable; boundless
3.euclidean-of or pertaining to Euclid, or adopting his postulates.
literary terms -
1.setting-space, Germany
2.exposition - The war was the excuse astronomers used for not understanding Einstein's theory.
outline -
Eisteins theories were even misunderstood by top astronomers. He understood how local time had to be transferred over to general time to make his theory work.
