In particular, he

158-501: A unified field theory that would unite gravity , electromagnetism , and nuclear forces within the basic framework of general relativity , doing the work with an extended correspondence with Albert Einstein. In 1947, he announced a result, "Affine Field Theory", in a talk at the Royal Irish Academy, but the announcement was criticized by Einstein as "preliminary" and failed to lead to the desired unified theory. Following

237-579: A unified field theory . In his book What Is Life? Schrödinger addressed the problems of genetics , looking at the phenomenon of life from the point of view of physics. He also paid great attention to the philosophical aspects of science, ancient, and oriental philosophical concepts, ethics, and religion. He also wrote on philosophy and theoretical biology. In popular culture, he is best known for his " Schrödinger's cat " thought experiment . Spending most of his life as an academic with positions at various universities, Schrödinger, along with Paul Dirac , won

316-422: A 14-year-old girl named "Ithi" Junger. Walter Moore relates in his 1989 biography of Schrödinger that the lessons "included 'a fair amount of petting and cuddling ' " and Schrödinger "had fallen in love with his pupil". Moore further relates that "not long after her seventeenth birthday, they became lovers". The relationship continued and in 1932 she became pregnant (then aged 20). "Erwin tried to persuade her to have

In 1920 he became the assistant to Max Wien , in Jena , and in September 1920 he attained the position of ao. 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 (now Wrocław, Poland). In 1921, he moved to

In his 1956 lecture "Mind and Matter", he said that "The world extended in space and time is but our representation ." This is a repetition of the first words of Schopenhauer's main work. Schopenhauer's works also introduced him to Indian philosophy , more specifically to the Upanishads and Advaita Vedanta ’s interpretation. He once took on

Early in his life, Schrödinger experimented in the fields of electrical engineering , atmospheric electricity , and atmospheric radioactivity , but he usually worked with his former teacher Franz Exner. He also studied vibrational theory,

711-559: A long-term arrangement in Dublin , Ireland, where he remained until retirement in 1955, and where he pursued several sexual relationships with minors. Schrödinger was born in Erdberg  [ de ] , Vienna , Austria , on 12 August 1887, to Rudolf Schrödinger ( cerecloth producer, botanist) and Georgine Emilia Brenda Schrödinger (née Bauer) (daughter of Alexander Bauer  [ de ] , professor of chemistry, TU Wien ). He

He wrote around 50 further publications on various topics, including his explorations of unified field theory . In 1944, he wrote What Is Life? , which contains a discussion of negentropy and the concept of a complex molecule with the genetic code for living organisms . According to James D. Watson 's memoir, DNA,

How come your world and my world are the same? If something happens in my world, does it happen in your world, too? What causes all these worlds to synchronize with each other?". There is obviously only one alternative, namely the unification of minds or consciousnesses. Their multiplicity

1027-607: A series of papers in this area: His work on the psychology of color perception follows the step of Isaac Newton , James Clerk Maxwell and Hermann von Helmholtz in the same area. Some of these papers have been translated into English and can be found in: Sources of Colour Science , Ed. David L. MacAdam, MIT Press (1970) and in Erwin Schrödinger’s Color Theory, Translated with Modern Commentary , Ed. Keith K. Niall, Springer (2017). ISBN   978-3-319-64619-0 doi : 10.1007/978-3-319-64621-3 . Schrödinger had

1106-700: A unique relationship to Ireland. In October 1940, a writer from the Irish Press interviewed Schrödinger who spoke of Celtic heritage of Austrians, saying: "I believe there is a deeper connection between us Austrians and the Celts. Names of places in the Austrian Alps are said to be of Celtic origin." He became the Director of the School for Theoretical Physics in 1940 and remained there for 17 years. He became

1185-536: Is > 0K. For this result Hasenöhrl was awarded the Haitinger Prize of the Austrian Academy of Sciences . He wrote in 1904: Since the heat content of every body partly consists of radiating heat, the things that we have demonstrated at a cavity, are true mutatis mutandis for every body whose temperature is different from 0° A.. In particular, every body must have an apparent mass determined by

As of October 2018 , there are approximately 1,689 living Fellows, Foreign and Honorary Members, of whom 85 are Nobel Laureates. Fellowship of

1343-414: Is analogous to the so-called 4/3 problem of electromagnetic mass. That is, if Hasenöhrl had included the shell in his calculations in a way consistent with relativity, the pre-factor of 4/3 would have been 1, so yielding m = E / c 2 {\displaystyle m=E/c^{2}} . He could not have done this, since he did not have relativistic mechanics, with which he could model

1422-737: Is confirmed by the Council in April, and a secret ballot of Fellows is held at a meeting in May. A candidate is elected if they secure two-thirds of votes of those Fellows voting. An indicative allocation of 18 Fellowships can be allocated to candidates from Physical Sciences and Biological Sciences; and up to 10 from Applied Sciences, Human Sciences and Joint Physical and Biological Sciences. A further maximum of six can be 'Honorary', 'General' or 'Royal' Fellows. Nominations for Fellowship are peer reviewed by Sectional Committees, each with at least 12 members and

1501-598: Is his most enduring legacy at a more technical level. Schrödinger is one of several individuals who have been called "the father of quantum mechanics". The large crater Schrödinger , on the far side of the Moon , is named after him. The Erwin Schrödinger International Institute for Mathematical Physics was founded in Vienna in 1992. Schrödinger's portrait was the main feature of the design of

Previously, nominations required at least five fellows to support each nomination by the proposer, which was criticised for supposedly establishing an old boy network and elitist gentlemen's club . The certificate of election (see for example ) includes a statement of the principal grounds on which

1659-496: Is now known as the Schrödinger equation. In this paper, he gave a "derivation" of the wave equation for time-independent systems and showed that it gave the correct energy eigenvalues for a hydrogen-like atom. This paper has been universally celebrated as one of the most important achievements of the twentieth century and created a revolution in most areas of quantum mechanics and indeed of all physics and chemistry.

1738-509: Is only apparent, in truth there is only one mind. This is the doctrine of the Upanishads. Schrödinger discussed topics such as consciousness , the mind–body problem , sense perception , free will , and objective reality in his lectures and writings. Schrödinger's attitude with respect to the relations between Eastern and Western thought was one of prudence, expressing appreciation for Eastern philosophy while also admitting that some of

1817-608: Is precisely a mass-energy relation that he is trying to establish. [...] Let us end by saying that Fritz Hasenöhrl attempted a legitimate thought experiment and tackled it with the tools available at the time. He was working during a transition period and did not create the new theory necessary to allow him to solve the problem correctly and completely. Nevertheless, his basic conclusion remained valid and for that he should be given credit. The equations for electromagnetic mass, like those of Hasenöhrl's (for example, Heaviside (1889), Poincaré (1900), Abraham (1902)), formally similar to

1896-589: Is recognized for postulating the Schrödinger equation , an equation that provides a way to calculate the wave function of a system and how it changes dynamically in time. He coined the term " quantum entanglement ", and was the earliest to discuss it, doing so in 1932. In addition, he wrote many works on various aspects of physics : statistical mechanics and thermodynamics , physics of dielectrics , colour theory , electrodynamics , general relativity , and cosmology , and he made several attempts to construct

1975-772: The 1983–97 Austrian 1000-schilling banknote , the second-highest denomination. A building is named after him at the University of Limerick , in Limerick, Ireland, as is the 'Erwin Schrödinger Zentrum' at Adlershof in Berlin and the Route Schrödinger at CERN , Prévessin , France.

2054-718: The First World War broke out in 1914, he volunteered at once into the Austria-Hungarian army. He fought as Oberleutnant against the Italians in Tyrol . He was wounded, recovered and returned to the front. He was then killed by a grenade in an attack on Mount Plaut (Folgaria) on 7 October 1915 at the age of 40. Since J. J. Thomson in 1881, many physicists like Wilhelm Wien (1900), Max Abraham (1902), and Hendrik Lorentz (1904) used equations equivalent to for

His wife, Anny (born 3 December 1896), died on 3 October 1965. One of Schrödinger's grandchildren, Terry Rudolph , has followed in his footsteps as a quantum physicist, and teaches at Imperial College London . At the age of 39, Schrödinger tutored

2291-645: The University of Vienna under Joseph Stefan (1835–1893) and Ludwig Boltzmann (1844–1906). In 1896, he attained a doctorate under Franz-Serafin Exner with a thesis titled "Über den Temperaturkoeffizienten der Dielektrizitätskonstante in Flüssigkeiten und die Mosotti-Clausius'sche Formel". He worked under Heike Kamerlingh Onnes in Leiden at the low temperature laboratory, and there he also befriended H. A. Lorentz . In 1907 he became Boltzmann's successor at

2370-791: The University of Zürich . In 1927, he succeeded Max Planck at the Friedrich Wilhelm University in Berlin. In 1933, Schrödinger decided to leave Germany because he strongly disapproved of the Nazis' antisemitism. He became a Fellow of Magdalen College at the University of Oxford . Soon after he arrived, he received the Nobel Prize in Physics together with Paul Dirac . His position at Oxford did not work out well; his unconventional domestic arrangements, sharing living quarters with two women, were not met with acceptance. In 1934, Schrödinger lectured at Princeton University ; he

This case is of historic interest, since it can be treated by electrodynamics alone, even without relativity theory. Then one necessarily comes to ascribe momentum and thus inertial mass to the moving radiation energy. It's interesting that this result was already found by F. Hasenöhrl before

Additionally, Schrödinger reportedly never collaborated with a major physicist for the remainder of his career. Schrödinger had a strong interest in psychology , in particular color perception and colorimetry (German: Farbenmetrik ). He spent quite a few years of his life working on these questions and published

Each candidate is considered on their merits and can be proposed from any sector of the scientific community. Fellows are elected for life on the basis of excellence in science and are entitled to use

3634-452: The first years of his career, Schrödinger became acquainted with the ideas of the old quantum theory , developed in the works of Einstein, Max Planck , Niels Bohr , Arnold Sommerfeld , and others. This knowledge helped him work on some problems in theoretical physics , but the Austrian scientist at the time was not yet ready to part with the traditional methods of classical physics .

The philosophical issues raised by Schrödinger's cat are still debated today and remain his most enduring legacy in popular science , while Schrödinger's equation

3871-415: The ideas did not fit with empirical approaches to natural philosophy. Some commentators have suggested that Schrödinger was so deeply immersed in a non-dualist Vedântic-like view that it may have served as a broad framework or subliminal inspiration for much of his work including that in theoretical physics. Schrödinger expressed sympathy for the idea of Tat Tvam Asi , stating "you can throw yourself flat on

3950-497: The inner radiation, and which is therefore above all dependent on the temperature. However, it was shown by Abraham that Hasenöhrl's calculation for the apparent mass was incorrect, so he published another paper in 1905, where he presented Abraham's criticism and corrected his formula to: This was the same relation (as Hasenöhrl noted himself) as for the electromagnetic mass formula given above. Hasenöhrl's results (concerning apparent mass and thermodynamics) by using cavity radiation

4108-521: The midst of these tenure issues in 1935, after extensive correspondence with Albert Einstein , he proposed what is now called the " Schrödinger's cat " thought experiment . In 1938, after the Anschluss , Schrödinger had problems in Graz because of his flight from Germany in 1933 and his known opposition to Nazism . He issued a statement recanting this opposition. He later regretted doing so and explained

4187-578: The other as Sheila May, though neither were students. The book also described an episode of Schrödinger being "infatuated" with a twelve-year-old girl, Barbara MacEntee, while in Ireland. He desisted from attentions after a "serious word" from someone, and later "listed her among the unrequited loves of his life." This episode from the book was highlighted by the Irish Times article and others. Walter Moore stated that Schrödinger's attitude towards women

Fellows elected under statute 12 include David Attenborough (1983) and John Palmer, 4th Earl of Selborne (1991). The Council of the Royal Society can recommend members of the British royal family for election as Royal Fellow of the Royal Society . As of 2023 there are four royal fellows: Elizabeth II

A 2021 Irish Times article summarized this as a "predilection for teenage girls", and denounced Schrödinger as "a serial abuser whose behaviour fitted the profile of a paedophile in the widely understood sense of that term". Schrödinger's grandson and his mother were unhappy with the accusation made by Moore, and once the biography was published, their family broke off contact with him. Carlo Rovelli notes in his book Helgoland that Schrödinger "always kept

4424-510: The priest in charge of the cemetery permitted the burial after learning Schrödinger was a member of the Pontifical Academy of Sciences . On April 6, 1920, Schrödinger married Annemarie (Anny) Bertel. When he migrated to Ireland in 1938, he obtained visas for himself, his wife and also another woman, Hilde March. March was the wife of an Austrian colleague and Schrödinger had fathered a daughter with her in 1934. Schrödinger wrote to

4503-622: The probability interpretation of quantum mechanics, saying, "I don't like it, and I'm sorry I ever had anything to do with it." (Just in order to ridicule the Copenhagen interpretation of quantum mechanics, he contrived the famous thought experiment called Schrödinger's cat paradox and was said to have angrily complained to his students that " now the damned Göttingen physicists use my beautiful wave mechanics for calculating their shitty matrix elements. ") Following his work on quantum mechanics, Schrödinger devoted considerable effort to working on

4582-560: The process of emission of radiation). Although the Bothe–Geiger coincidence experiment soon cast doubt on this, the idea of energy as a statistical concept was a lifelong attraction for Schrödinger, and he discussed it in some reports and publications. In January 1926, Schrödinger published in Annalen der Physik the paper " Quantisierung als Eigenwertproblem " (Quantization as an Eigenvalue Problem) on wave mechanics and presented what

4661-552: The proposal is being made. There is no limit on the number of nominations made each year. In 2015, there were 654 candidates for election as Fellows and 106 candidates for Foreign Membership. The Council of the Royal Society oversees the selection process and appoints 10 subject area committees, known as Sectional Committees, to recommend the strongest candidates for election to the Fellowship. The final list of up to 52 Fellowship candidates and up to 10 Foreign Membership candidates

4740-420: The reason he [Hasenöhrl] achieved an incorrect result on both occasions is that he wants to rigorously equate the work performed to kinetic energy, as the work-energy theorem demands. Unfortunately, he does not know how to properly compute the energy. In particular, Hasenöhrl does not conceive of the fact that if the radiators are losing energy, they must be losing mass, which contains an element of irony because it

4819-481: The reason to Einstein: "I wanted to remain free – and could not do so without great duplicity". However, this did not fully appease the new dispensation and the University of Graz dismissed him from his post for political unreliability. He suffered harassment and was instructed not to leave the country. He and his wife, however, fled to Italy. From there, he went to visiting positions in Oxford and Ghent University . In

He moved to Kincora Road, Clontarf, Dublin , and lived modestly. A plaque has been erected at his Clontarf residence and at the address of his workplace in Merrion Square . Schrödinger believed that as an Austrian he had

4977-532: The same year, he created the Schrödinger equation of the relativistic Doppler effect for spectral lines, based on the hypothesis of light quanta and considerations of energy and momentum. He liked the idea of his teacher Exner on the statistical nature of the conservation laws, so he enthusiastically embraced the BKS theory of Bohr, Hans Kramers , and John C. Slater , which suggested the possibility of violation of these laws in individual atomic processes (for example, in

5056-402: The shell. On the other hand, Stephen Boughn and Tony Rothman in 2011 (and Boughn in 2012 ), who gave a historical account of different solutions to the problem, argued that the above explanation is insufficient. After providing a complete relativistic description and solution of the cavity problem (in the "constant velocity case" and "slow acceleration case"), they wrote: ... more generally

5135-409: The so-called " electromagnetic mass ", which expresses how much electromagnetic energy contributes to the mass of bodies. Following this line of thought, Hasenöhrl (1904, 1905) published several papers on the inertia of a cavity containing radiation. This was an entirely classical (non-relativistic) derivation and used Maxwell's equation for the pressure of light . Hasenöhrl specifically associated

5214-419: The system changes with time, as in scattering problems. In this paper, he introduced a complex solution to the wave equation in order to prevent the occurrence of fourth- and sixth-order differential equations. Schrödinger ultimately reduced the order of the equation to one. Schrödinger was not entirely comfortable with the implications of quantum theory referring to his theory as "wave mechanics". He wrote about

5293-423: The theories of Mosengeil and Planck. However, he complained about the fact that Planck (1907) did not mention his earlier 1904-results (like the dependency of apparent mass on temperature). In 1908 Planck wrote that the results of Hasenöhrl's new approach from 1907 were indeed equivalent to those of relativity. Afterwards, several authors gave credit to Hasenöhrl for his 1904 achievements on cavity radiation. That

5372-716: The theory of Brownian motion , and mathematical statistics . In 1912, at the request of the editors of the Handbook of Electricity and Magnetism , Schrödinger wrote an article titled Dielectrism . That same year, Schrödinger gave a theoretical estimate of the probable height distribution of radioactive substances, which is required to explain the observed radioactivity of the atmosphere, and in August 1913 executed several experiments in Zeehame that confirmed his theoretical estimate and those of Victor Franz Hess. For this work, Schrödinger

5451-473: The theory of spectra began to emerge only from the beginning of the 1920s, after his personal acquaintance with Sommerfeld and Wolfgang Pauli and his move to Germany. In January 1921, Schrödinger finished his first article on this subject, about the framework of the Bohr–Sommerfeld quantization of the interaction of electrons on some features of the spectra of the alkali metals. Of particular interest to him

Helge Kragh , in his review of Moore's biography, said the "conquest of women, especially very young women, was the salt of life for this sincere romantic and male chauvinist". The physics department of Trinity College Dublin announced in January 2022 that they would recommend

5609-514: Was British. Between 1906 and 1910 (the year he earned his doctorate) Schrödinger studied at the University of Vienna under the physicists Franz S. Exner (1849–1926) and Friedrich Hasenöhrl (1874–1915). He received his doctorate at Vienna under Hasenöhrl. He also conducted experimental work with Karl Wilhelm Friedrich "Fritz" Kohlrausch. In 1911, Schrödinger became an assistant to Exner. In 1914 Schrödinger achieved habilitation ( venia legendi ). Between 1914 and 1918 he participated in war work as

5688-602: Was awarded the 1920 Haitinger Prize (Haitinger-Preis) of the Austrian Academy of Sciences. Other experimental studies conducted by the young researcher in 1914 were checking formulas for capillary pressure in gas bubbles and the study of the properties of soft beta radiation produced by gamma rays striking a metal surface. The last work he performed together with his friend Fritz Kohlrausch. In 1919, Schrödinger performed his last physical experiment on coherent light and subsequently focused on theoretical studies. In

5767-438: Was further elaborated and criticized by Kurd von Mosengeil (1906/7) who already incorporated Albert Einstein 's theory of relativity in his work. A broad outline of relativistic thermodynamics and mass-energy equivalence using cavity radiation was given by Max Planck in 1907. In some additional papers (1907, 1908) Hasenöhrl elaborated further on his 1904-work and concluded that his new results were now in accordance to

5846-421: Was not a Royal Fellow, but provided her patronage to the society, as all reigning British monarchs have done since Charles II of England . Prince Philip, Duke of Edinburgh (1951) was elected under statute 12, not as a Royal Fellow. The election of new fellows is announced annually in May, after their nomination and a period of peer-reviewed selection. Each candidate for Fellowship or Foreign Membership

5925-551: Was offered a permanent position there, but did not accept it. Again, his wish to set up house with his wife and his mistress may have created 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. He had also accepted the offer of chair position at Department of Physics, Allahabad University in India. In

6004-474: Was submitted just four weeks later that solved the quantum harmonic oscillator , rigid rotor , and diatomic molecule problems and gave a new derivation of the Schrödinger equation. A third paper, published in May, showed the equivalence of his approach to that of Werner Heisenberg 's matrix mechanics and gave the treatment of the Stark effect . A fourth paper in this series showed how to treat problems in which

6083-405: Was the introduction of relativistic considerations in quantum theory. In autumn 1922, he analyzed the electron orbits in an atom from a geometric point of view, using methods developed by his friend Hermann Weyl . This work, in which it was shown that quantum orbits are associated with certain geometric properties, was an important step in predicting some of the features of wave mechanics. Earlier in

6162-511: Was their only child. His mother was of half Austrian and half English descent; his father was Catholic and his mother was Lutheran . He himself was an atheist . However, he had strong interests in Eastern religions and pantheism , and he used religious symbolism in his works. He also believed his scientific work was an approach to divinity in an intellectual sense. He was also able to learn English outside school, as his maternal grandmother

6241-602: Was written for the School's 1955 edition of their Blue Coat to celebrate his leaving of Dublin to take up his appointment as Chair of Physics at the University of Vienna. In 1956, he returned to Vienna (chair ad personam ). At an important lecture during the World Energy Conference he refused to speak on nuclear energy because of his scepticism about it and gave a philosophical lecture instead. During this period, Schrödinger turned from mainstream quantum mechanics' definition of wave–particle duality and promoted
