“God knows I am no friend of probability theory, I have hated it from the first moment when our dear friend Max Born gave it birth. For it could be seen how easy and simple it made everything, in principle, everything ironed and the true problems concealed. Everybody must jump on the bandwagon [Ausweg]. And actually not a year passed before it became an official credo, and it still is[i].” [1]

“I am very astonished that the scientific picture of the real world around me is deficient. It gives a lot of factual information, puts all our experience in a magnificently consistent order, but it is ghastly silent about all and sundry that is really near to our heart, that really matters to us. It cannot tell us a word about red and blue, bitter and sweet, physical pain and physical delight; it knows nothing of beautiful and ugly, good or bad, God and eternity. Science sometimes pretends to answer questions in these domains, but the answers are very often so silly that we are not inclined to take them seriously.”
The request for March stemmed from Schrödinger’s unconventional relationships with women: although his relations with his wife Anny were good, he had had many lovers with his wife’s full knowledge (and in fact, Anny had her own lover, Hermann Weyl). Schrödinger asked for March to be his assistant because, at that time, he was in love with March’s wife Hilde.

[ii] Schrödinger’s cat is a thought experiment (see Chapter 37), usually described as a paradox, that Austrian physicist Erwin Schrödinger devised in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The thought experiment presents a cat that might be alive or dead, depending on an earlier random event. In the course of developing this experiment, he coined the term Verschränkung (entanglement).
[iii] Franz Serafin Exner (24 March 1849 - October 15, 1926) was an Austrian physicist.
[iv] Friedrich Hasenöhrl (November 30, 1874 - October 7, 1915) was an Austro-Hungarian physicist.
[v] Arthur Schopenhauer (22 February 1788 – 21 September 1860) was a German philosopher known for his pessimism and philosophical clarity.
[vi] In his lecture "Mind and Matter," Chapter 4, he said that a phrase "that has become familiar to us" is "The world extended in space and time is but our representation (Vorstellung)." This is a repetition of the first words of Schopenhauer’s main work.
[vii] Vedānta was originally a word used in Hindu philosophy as a synonym for that part of the Veda texts known also as the Upanishads.
[viii] Habilitation is the highest academic qualification a scholar can achieve by his or her own pursuit in several European and Asian countries. Earned after obtaining a research doctorate, such as a Ph.D., habilitation requires the candidate to write a professorial thesis (often known as a Habilitationsschrift, or Habilitation thesis) based on independent scholarship, reviewed by and defended before an academic committee in a process similar to that for the doctoral dissertation. However, the level of scholarship has to be considerably higher than that required for a research doctoral (Ph.D.) thesis in terms of quality and quantity, and must be accomplished independently, in contrast with a Ph.D. dissertation typically directed or guided by a faculty supervisor.
[ix] The eigenvectors of a square matrix are the non-zero vectors that, after being multiplied by the matrix, remain proportional to the original vector (i.e., change only in magnitude, not in direction). For each eigenvector, the corresponding eigenvalue is the factor by which the eigenvector changes when multiplied by the matrix. The prefix eigen- is adopted from the German word "eigen" for "own" in the sense of a characteristic description. The eigenvectors are sometimes also called characteristic vectors. Similarly, the eigenvalues are also known as characteristic values.
[x] The Schrödinger equation was formulated in 1926 by Austrian physicist Erwin Schrödinger. Used in physics, specifically quantum mechanics, it is an equation that describes how the quantum state of a physical system changes in time. In the standard interpretation of quantum mechanics, the quantum state, also called a wavefunction or state vector, is the most complete description that can be given to a physical system. Solutions to Schrödinger’s equation describe not only molecular, atomic and subatomic systems, but also macroscopic systems, possibly even the whole universe.
[xi] The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator. Because an arbitrary potential can be approximated as a harmonic potential at the vicinity of a stable equilibrium point, it is one of the most important model systems in quantum mechanics. Furthermore, it is one of the few quantum-mechanical systems for which a simple, exact solution is known.
[xii] The rigid rotor is a mechanical model that is used to explain rotating systems. An arbitrary rigid rotor is a 3-dimensional rigid object, such as a top. To orient such an object in space three angles are required. A special rigid rotor is the linear rotor that is a 2-dimensional object, requiring two angles to describe its orientation. An example of a linear rotor is a diatomic molecule. More general molecules like water (asymmetric rotor), ammonia (symmetric rotor), or methane (spherical rotor) are 3-dimensional, see classification of molecules.
[xiii] Diatomic molecules are molecules composed only of two atoms, of either the same or the different chemical elements. The prefix di- means two in Greek. Common diatomic molecules are hydrogen (H2), nitrogen (N2), oxygen (O2), and carbon monoxide (CO). Seven elements exist in the diatomic state in the liquid and solid forms: H2 , N2, O2, F2, Cl2, Br2, and I2. Most elements (and many chemical compounds) aside from these form diatomic molecules when evaporated, although at very high temperatures, all materials disintegrate into atoms. The noble gases do not form diatomic molecules.
[xiv] The Stark effect (named after Johannes Starck)is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external static electric field. The amount of splitting and or shifting is called the Stark splitting or Stark shift.
[xv] The Anschluss (spelled Anschluß at the time of the event, and until the German orthography reform of 1996; German for "link-up"), also known as the Anschluss Österreichs, was the occupation and annexation of Austria into Nazi Germany in 1938.
[xvi] Éamon de Valera(14 October 1882 – 29 August 1975) was one of the dominant political figures in twentieth century Ireland, serving as head of government and head of state and introducing the Constitution of Ireland. De Valera was a leader of Ireland’s struggle for independence from Britain in the Irish War of Independence and of the anti-Treaty forces in the ensuing Irish Civil War (1922–23). In 1926, he founded Fianna Fáil and was head of government from 1932–48, 1951–54 and 1957–59 and President of Ireland from 1959–73.
[xvii] Since the 19th century, some physicists have attempted to develop a single theoretical framework that can account for the fundamental forces of nature—a unified field theory. Classical unified field theories are attempts to create a unified field theory based on classical physics. In particular, unification of gravitation and electromagnetism was actively pursued by several physicists and mathematicians in the years between World War I and World War II. This work spurred the purely mathematical development of differential geometry. Albert Einstein is the best known of the many physicists who attempted to develop a classical unified field theory.
[xviii] The negentropy, also negative entropy or syntropy, of a living system is the entropy that it exports to keep its own entropy low; it lies at the intersection of entropy and life. The concept and phrase "negative entropy" were introduced by Erwin Schrödinger in his 1943 popular-science book What is Life?
[xix] Colorimetry is "the science and technology used to quantify and describe physically the human color perception."
