erwin schrdinger

Erwin Rudolf Josef Alexander Schrdinger (August 12, 1887 – January 4, 1961), an Austrian physicist, achieved fame for his contributions to quantum mechanics, especially the Schrdinger equation, for which he won the Nobel Prize in 1933. He proposed the Schrdinger's cat thought experiment, and he had a life-long interest in Vedanta.

Biography

Early years

In 1887 Schrdinger was born in Erdberg, Vienna to Rudolf Schrdinger (cerecloth producer, botanist) and Georgine Emilia Brenda (daughter of Alexander Bauer, Professor of Chemistry, k.u.k. Technische Hochschule Vienna). In 1898 he attended the Akademisches Gymnasium. Between 1906 and 1910 Schrdinger studied in Vienna under Franz Serafin Exner (1849 - 1926) and Friedrich Hasenhrl (1874 - 1915). He also conducted experimental work in Kohlrausch. In 1911, Schrdinger became an assistant to Exner.

Middle years

In 1914 Erwin Schrdinger achieved Habilitation (venia legendi). Between 1914 and 1918 he participated in war work (Grz, Duino, Sistiana, Prosecco, Vienna). On April 6 1920 Schrdinger married Annemarie Bertel. In 1920, he became the assistant to Max Wien, in Jena. In September 1920 he attained the position of a. o. Prof. (Ausserordentlicher Professor), roughly equivalent to Reader (UK) or associate professor (US)), in Stuttgart. In 1921, he became o. Prof. (Ordentlicher Professor, i.e. full professor), in Breslau (presently Wroclaw, Poland) In 1922, he went to Zrich University. In 1926, Schrdinger published in the Annalen der Physik the paper "Quantisierung als Eigenwertproblem" Quantisation as an Eigenvalue Problem on wave mechanics and what is now known as the Schrdinger equation. In 1927, he joined Max Planck at the Friedrich Wilhelm University in Berlin. In 1933, however, Schrdinger decided to leave Germany; he disliked the Nazis' anti-semitism. He became a Fellow of Magdalen College at the University of Oxford. Soon after he arrived, he received the Nobel Prize together with Paul Adrien Maurice Dirac. His position at Oxford did not work out, it seems that his unconventional personal life (Schrdinger lived with two women) did not meet with acceptance. In 1934, Schrdinger lectured at Princeton University and though offered a permanent position there did not accept it. Again, his wish to set up house with his wife and his mistress may have posed a problem. He had the prospect of a position at the University of Edinburgh but visa delays occurred, and in the end he took up a position at the University of Graz in Austria in 1936.

Later years

In 1938, after Hitler occupied Austria, he had problems due to leaving Germany in 1933 and his known opposition to Nazism. He issued a statement recanting this opposition, something he later regretted and for which he personally apologized to Einstein. However, this did not fully appease the new dispensation and he was dismissed from his job for political unreliability. He suffered harassment and was told not to leave the country. He and his wife fled to Italy. From there he went to visiting positions in the Oxford and Ghent Universities. In 1940 he was asked to help establish an Institute for Advanced Studies in Dublin, Ireland. He became the Director of the School for Theoretical Physics and remained there for 17 years. He wrote about 50 further publications on various topics. These were attempts towards a unified field theory. In 1944, he wrote "What is Life?" (which contains Negentropy, concepts for genetic code). According to James D. Watson's memoir, DNA, The Secret of Life, Schrdinger's 1944 book What is Life? gave Watson the inspiration to research the gene, which led to the discovery of the DNA double helix structure. He stayed in Dublin until retirement. During this time he remained committed to his particular passion; there were scandalous involvements with students and he fathered two children by two different Irish women. In 1956, he returned to Vienna (chair ad personam). At an important lecture during the World Power Conference he refused to speak on nuclear energy because of his scepticism about it (he gave a philosophical lecture instead).
