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Energeticism, also called energism or energetics [lower-alpha 1] (German : Energetik), [1] is a superseded theory in science that posits that energy is the ultimate element of physical reality.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 the chemist Wilhelm Ostwald and mathematician Georg Helm. It was also promoted by physicist Ernst Mach, 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 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, 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]

Ostwald's renunciation as a physical theory

Under the evidence of Jean Baptiste Perrin's experiments on Brownian motion that confirmed Albert Einstein's theory, Ostwald renounced to energeticism as physical theory in his fourth edition of Outline of General Chemistry in 1908, embracing atomic theory. [7] [3] However he modified energeticism into an ontological philosophy, supported by the recently discovered Einstein's mass–energy equivalence E=mc2. [3]

Sociology and culture

After 1908, Ostwald redirected his philosophy to sociological and cultural phenomena as part of sociological energetics (German : Soziologische Energetik). [8] He attempted to create a hierarchy to classify the sciences and social sciences based on life, energy and order. [8]

Sociologist Max Weber oppossed Ostwald views. In 1909, Weber accussed sociological energetics of being ideological, underrating the complexity of the social sciences and overrating the importance of recasting phenomena in energetic terminology. Weber also objects to the idea of 'psychological energy' to explain psychology and accusses Ostwald of trying to derive an 'is from an ought'. [8]

In physics, a correspondence principle is any one of several premises or assertions about the relationship between classical and quantum mechanics. The physicist Niels Bohr coined the term in 1920 during the early development of quantum theory; he used it to explain how quantized classical orbitals connect to quantum radiation. Modern sources often use the term for the idea that the behavior of systems described by quantum theory reproduces classical physics in the limit of large quantum numbers: for large orbits and for large energies, quantum calculations must agree with classical calculations. A "generalized" correspondence principle refers to the requirement for a broad set of connections between any old and new theory.

Max Planck named the constant kB the Boltzmann constant.

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 which were both premised on the Arnold Sommerfeld enhancements to the Bohr model of the atom.

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.

<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. Owing in 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.

This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process. Multiple discovery sometimes occurs when multiple research groups discover the same phenomenon at about the same time, and scientific priority is often disputed. The listings below include some of the most significant people and ideas by date of publication or experiment.

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.

The Planck constant, or Planck's constant, denoted by , is a fundamental physical constant of foundational importance in quantum mechanics: a photon's energy is equal to its frequency multiplied by the Planck constant, and the wavelength of a matter wave equals the Planck constant divided by the associated particle momentum.
