Sidelights On Relativity

One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of all other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts. In spite of this, the investigator in another department of science would not need to envy the mathematician if the laws of mathematics referred to objects of our mere imagination, and not to objects of reality. For it cannot occasion surprise that different persons should arrive at the same logical conclusions when they have already agreed upon the fundamental laws (axioms), as well as the methods by which other laws are to be deduced therefrom.

Review: Sidelights on Relativity

User Review  - Josh - Goodreads

Einstein lays out in a logical and intuitive way some of the more difficult concepts to grasp in general relativity. Loved it. Read full review

About the author (2004)

Albert Einstein, March 14, 1879 - April 18, 1955 Albert Einstein was born on March 14, 1879 in Ulm. He spent his childhood in Munich where his family owned a small machine shop. By the age of twelve, Einstein had taught himself Euclidean geometry. His family moved to Milan, where he stayed for a year, and he used it as an excuse to drop out of school, which bored him. He finished secondary school in Aarau, Switzerland and entered the Swiss Federal Institute of Technology in Zurich. Einstein graduated in 1900, by studying the notes of a classmate since he did not attend his classes out of boredom, again. His teachers did not like him and would not recomend him for a position in the University. For two years, Einstein worked as a substitute teacher and a tutor before getting a job, in 1902, as an examiner for a Swiss patent office in Bern. In 1905, he received his doctorate from the University of Zurich for a theoretical dissertation on the dimension of molecules. Einstein also published three theoretical papers of central importance to the development of 20th Century physics. The first was entitled "Brownian Motion," and the second "Photoelectric Effort," which was a revolutionary way of thinking and contradicted tradition. No one accepted the proposals of the first two papers. Then the third one was published in 1905 and called "On the Electrodynamics of Moving Bodies." Einstein's words became what is known today as the special theory of relativity and said that the physical laws are the same in all inertial reference systems and that the speed of light in a vacuum is a universal constant. Virtually no one understood or supported Einstein's argument. Einstein left the patent office in 1907 and received his first academic appointment at the University of Zurich in 1909. In 1911, he moved to a German speaking University in Prague, but returned to Swiss National Polytechnic in Zurich in 1912. By 1914, Einstein was appointed director of the Kaiser Wilhelm Institute of Physics in Berlin. His chief patron in those early days was German physicist Max Planck and lent much credibility to Einstein's work. Einstein began working on generalizing and extending his theory of relativity, but the full general theory was not published until 1916. In 1919, he predicted that starlight would bend in the vicinity of a massive body, such as the sun. This theory was confirmed during a solar eclipse and cause Einstein to become world renowned after the phenomenon. Einstein received be Nobel Prize in Physics in 1921. With his new fame, Einstein attempted to further his own political and social views. He supported pacifism and Zionism and opposed Germany's involvement in World War I. His support of Zionism earned him attacks from both Anti-Semitic and right wing groups in Germany. Einstein left Germany for the United States when Hitler came into power, taking a position at the Institute for Advanced Study in Princeton, New Jersey. Once there, he renounced his stand on pacifism in the face of Nazi rising power. In 1939 he collaborated with other physicists in writing a letter to President Franklin D. Roosevelt informing him of the possibility that the Nazis may in fact be attempting to create an atomic bomb. The letter bore only Einstein's signature but lent credence to the letter and spurred the U.S. race to create the bomb first. After the war, Einstein was active in international disarmament as well as world government. He was offered the position of President of Israel but turned the honor down. Albert Einstein died on April 18, 1955 in Princeton, New Jersey.
