Energeticism

Last updated

Energeticism, also called energism or energetics [lower-alpha 1] (German : Energetik), [1] is a superseded theory in science that posits that energy is the ultimate element of physical reality. Energeticism was developed during the end of the 19th century by Wilhelm Ostwald, Georg Helm and Pierre Duhem. It was also promoted by physicist Ernst Mach who opposed atomic theory, though his full commitment to it was sometimes ambiguous. [2] Energetiscism attempted to substitute the hypothesis of atoms and molecules by energy relations. [3]

Contents

Ludwig Boltzmann and Max Planck constantly rebutted the idea of energeticism [3] in favor of atomic theory. The program of energeticism faded away in the 20th century with the experimental confirmation of the existence of atoms.

Origin

While teaching chemistry in Riga Polytechnic Institute, Wilhelm Ostwald became convinced that certain reactions could only be explained in terms of energy, without the need of invoking the hypothesis of the existence of atoms. He was inspired by Josiah Willard Gibbs's work on thermodynamics. [4] During an inaugural lecture in 1887 in Leipzig University, Ostwald outlined his program of energetics as an alternative to atomic theory. In his second edition of his textbook on physical chemistry of 1892, he stressed that energetic ideas should avoid all atomistic considerations. [4] He opposed the reduction of chemistry to mechanics and advocated for the reduction of mass and matter to energy. [4]

In parallel, mathematician Georg Helm published his energy principle in The Theory of Energy (German : Die Lehre von der Energie) in 1887, as an extension to the principle of conservation of energy. In his essay of 1890, he proposed to reduce mechanics to energetics by means of his principle. In 1892, he proposed to do the same for electricity and magnetism. [5] His principle can be written as [5]

,

where dU is a change in the internal energy of a system, T is the temperature, dS is a change in the entropy, p is the pressure and dV a change in volume. [4] This principle recovers the first law of thermodynamics only when the equality holds. Helm changed the equal sign into an inequality in the hope to account for irreversible processes. [4]

Lübeck debate

In 1895, Boltzmann who supported atomic theory in light of his recently developed statistical mechanics, organized a debate with Ostwald to be held during a scientific conference in Lübeck, Germany. [3] Boltzmann had already prepared his arguments in private correspondence with Ostwald after the publication of his book. [3] The Lübeck Scientific Conference (German : Lübeck Naturforscherversammlung) took place in September of that year, with mathematician Georg Helm and Ostwald supporting energeticism in the debate, and Boltzmann and mathematician Felix Klein supporting atomism. [3] Mach was not present. [3] Arnold Sommerfeld records his impression of the conference: [3]

The fight between Boltzmann and Ostwald resembled, both externally and internally, the struggle between a bull and a supple fencer. But the bull defeated the matador in spite of all of the latter's fencing skill. The arguments of Boltzmann broke through. We, who were then young mathematicians, all supported Boltzmann. It was quite obvious to us that it was impossible to derive the motion equations of a single mass point from an energy equation, to say nothing of optional degrees of freedom.

After the conference, Helm and Ostwald hurried to write response articles. Mach finished his book Principles of the Theory of Heat in 1886, in which he recorded that energeticism, even if flawed, was better to Boltzmann's mechanistic theories. [3] Max Planck wrote an article after the conference "Against the New Energetics", in opposition to Ostwald's theory. [3] [6]

Duhem's energetics

In France, energetics (French : énergetique) was championed by physicist and science philosopher Pierre Duhem. He was convinced that all chemistry and physics, including mechanics, electricity and magnetism, could be derived from thermodynamic principles. [7] He opposed the idea of atoms as constituents of matter. [8]

Duhem wrote a publication in 1897 on chemical mechanics where he used the term energetics. [9] This publication developed into a thermodynamics course from 1898 to 1899, unofficially titled "Énergetique". [9] Duhem developed an specialized course on energetics from 1904 to 1909, to be published later. [9]

Duhem send a draft of his critique on James Clerk Maxwell's electrodynamics to Pierre Curie in 1902. He found Duhem's critique imprudent and lacking a proper alternative. Curie told Duhem "I am in complete disagreement with your theory of magnetism". [9]

In 1903, Jean Baptiste Perrin in his book Traité de la chimie physique [10] criticised energetics for its "theoretical obscurities". [9] A year later, Paul Langevin was the first to take his disagreement with Duhem publicly during symposium at the Musée de pédagogie in Paris. [9] Langevin referred to energeticism as an ignorabimus, attempting to set limitations on scientific knowledge. [11]

Duhem finally published his two volume "Treaty on energetics" (French : Traité d'energétique) in 1911 which was well received by Ostwald and Helm. [7] None of Albert Einstein contributions were mentioned. [9]

Ostwald's renunciation as a physical theory

Under the evidence of Perrin's experiments that confirmed Einstein's theory on Brownian motion, Ostwald renounced to energeticism as physical theory in his fourth edition of Outline of General Chemistry in 1908, embracing atomic theory. [12] [3] However he modified energeticism into an ontological philosophy, supported by the recently discovered Einstein's mass–energy equivalence E=mc2. [3]

By 1918 most physicists had adhered to atomic theory. [9]

Sociology and psychology

After 1908, Ostwald redirected his philosophy to sociological and cultural phenomena as part of sociological energetics (German : Soziologische Energetik). [13] He attempted to create a hierarchy to classify the sciences and social sciences based on life, energy and order. [13]

Sociologist Max Weber opposed Ostwald views. In 1909, Weber accused sociological energetics of being ideological, underrating the complexity of the social sciences and overrating the importance of recasting phenomena in energetic terminology. Weber also objected to the idea of 'psychological energy' to explain psychology and accused Ostwald of trying to derive an 'is from an ought'. [13]

Atomic theory is the scientific theory that matter is composed of particles called atoms. The definition of the word "atom" has changed over the years in response to scientific discoveries. Initially, it referred to a hypothetical concept of there being some fundamental particle of matter, too small to be seen by the naked eye, that could not be divided. Then the definition was refined to being the basic particles of the chemical elements, when chemists observed that elements seemed to combine with each other in ratios of small whole numbers. Then physicists discovered that these particles had an internal structure of their own and therefore perhaps did not deserve to be called "atoms", but renaming atoms would have been impractical by that point.

The old quantum theory is a collection of results from the years 1900–1925 which predate modern quantum mechanics. The theory was never complete or self-consistent, but was instead a set of heuristic corrections to classical mechanics. The theory has come to be understood as the semi-classical approximation to modern quantum mechanics. The main and final accomplishments of the old quantum theory were the determination of the modern form of the periodic table by Edmund Stoner and the Pauli exclusion principle, both of which were premised on Arnold Sommerfeld's enhancements to the Bohr model of the atom.

<span class="mw-page-title-main">History of chemistry</span>

The history of chemistry represents a time span from ancient history to the present. By 1000 BC, civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include the discovery of fire, extracting metals from ores, making pottery and glazes, fermenting beer and wine, extracting chemicals from plants for medicine and perfume, rendering fat into soap, making glass, and making alloys like bronze.

The deductive-nomological model of scientific explanation, also known as Hempel's model, the Hempel–Oppenheim model, the Popper–Hempel model, or the covering law model, is a formal view of scientifically answering questions asking, "Why...?". The DN model poses scientific explanation as a deductive structure, one where truth of its premises entails truth of its conclusion, hinged on accurate prediction or postdiction of the phenomenon to be explained.

<i>Annus mirabilis</i> papers Published papers of Albert Einstein in 1905

The annus mirabilis papers are the four that Albert Einstein published in the scientific journal Annalen der Physik in 1905. As major contributions to the foundation of modern physics, these scientific publications were the ones for which he gained fame among physicists. They revolutionized science's understanding of the fundamental concepts of space, time, mass, and energy. Because Einstein published all four of these papers in a single year, 1905 is called his annus mirabilis.

  1. The first paper explained the photoelectric effect, which established the energy of the light quanta , and was the only specific discovery mentioned in the citation awarding Einstein the 1921 Nobel Prize in Physics.
  2. The second paper explained Brownian motion, which established the Einstein relation and compelled physicists to accept the existence of atoms.
  3. The third paper introduced Einstein's special theory of relativity, which proclaims the constancy of the speed of light and derives the Lorentz transformations. Einstein also examined relativistic aberration and the transverse Doppler effect.
  4. The fourth, a consequence of special relativity, developed the principle of mass–energy equivalence, expressed in the equation and which led to the discovery and use of nuclear power decades later.
<span class="mw-page-title-main">History of thermodynamics</span>

The history of thermodynamics is a fundamental strand in the history of physics, the history of chemistry, and the history of science in general. Due to the relevance of thermodynamics in much of science and technology, its history is finely woven with the developments of classical mechanics, quantum mechanics, magnetism, and chemical kinetics, to more distant applied fields such as meteorology, information theory, and biology (physiology), and to technological developments such as the steam engine, internal combustion engine, cryogenics and electricity generation. The development of thermodynamics both drove and was driven by atomic theory. It also, albeit in a subtle manner, motivated new directions in probability and statistics; see, for example, the timeline of thermodynamics.

The history of quantum mechanics is a fundamental part of the history of modern physics. The major chapters of this history begin with the emergence of quantum ideas to explain individual phenomena—blackbody radiation, the photoelectric effect, solar emission spectra—an era called the Old or Older quantum theories. Building on the technology developed in classical mechanics, the invention of wave mechanics by Erwin Schrödinger and expansion by many others triggers the "modern" era beginning around 1925. Paul Dirac's relativistic quantum theory work lead him to explore quantum theories of radiation, culminating in quantum electrodynamics, the first quantum field theory. The history of quantum mechanics continues in the history of quantum field theory. The history of quantum chemistry, theoretical basis of chemical structure, reactivity, and bonding, interlaces with the events discussed in this article.
