Dénis Lindbohm (1927–2005) was a Swedish author and occultist and is considered one of the founders of Swedish science fiction.
 In his early years, he worked as a photographic technician in Malmö and became involved in the nascent Swedish science fiction fandom.
 In the mid-1960s he became a full-time writer.
Jacobus Henricus van 't Hoff, Jr. (] ; 30 August 1852 – 1 March 1911) was a Dutch physical chemist.
 A highly influential theoretical chemist of his time, van 't Hoff was the first winner of the Nobel Prize in Chemistry.
 His pioneering work helped found the modern theory of chemical affinity, chemical equilibrium, chemical kinetics, and chemical thermodynamics.
 In his 1874 pamphlet Van 't Hoff formulated the theory of the tetrahedral carbon atom and laid the foundations of stereochemistry.
 In 1875, he predicted the correct structures of allenes and cumulenes as well as their axial chirality.
 He is also widely considered one of the founders of physical chemistry as the discipline is known today.
The Lorentz–Lorenz equation, also known as the Clausius–Mossotti relation and Maxwell's formula, relates the refractive index of a substance to its polarizability.
 Named after Hendrik Antoon Lorentz and Ludvig Lorenz.
Louis Semple Clarke, or Simpson Clarke or simply LS, was a pioneering businessman and engineer in the American automotive industry.
 One of the central founders of The Autocar Company, Clarke was also an inventor who made numerous contributions to the development of modern motor vehicles, including innovations in the use of the drive shaft, circulating motor oil, sparkplugs, and the American convention of placing a vehicle's steering wheel on the left.
Doreen Valiente is considered one of the founders of the modern “Wicca” movement along with Gerald Gardner, the man credited with reviving what has been described as Britain’s only indigenous religion, England being the birthplace of Wicca.
 She was also an author of great note in the field of magic, folklore, witchcraft and paganism and has been described by Professor Ronald Hutton of the University of Bristol as “.
.
 the greatest single female figure in the modern British history of witchcraft”.
 Doreen was also one of the founders of the organisation now called the Pagan Federation, which, more than 40 years on, continues to represent modern day pagans in mainstream society in areas such as law, government, hospitals, schools and the wider community.
 She has an entry in the "Oxford Dictionary of National Biography", was the author of books, which continue to sell today, and are frequently quoted as standard works in the study of contemporary paganism and modern British witchcraft.
 Both Doreen Valiente (Brighton) and Gerald Gardner (Highcliffe) have Heritage Blue Plaques commemorating the buildings where they lived.
In physics, geometrothermodynamics (GTD) is a formalism developed recently by Hernando Quevedo to describe the properties of thermodynamic systems in terms of concepts of differential geometry.
 Consider a thermodynamic system in the framework of classical equilibrium thermodynamics.
 The states of thermodynamic equilibrium are considered as points of an abstract equilibrium space in which a Riemannian metric can be introduced in several ways.
 In particular, one can introduce Hessian metrics like the Fisher information metric, the Weinhold metric, the Ruppeiner metric and others, whose components are calculated as the Hessian of a particular thermodynamic potential.
 Another possibility is to introduce metrics which are independent of the thermodynamic potential, a property which is shared by all thermodynamic systems in classical thermodynamics.
 Since a change of thermodynamic potential is equivalent to a Legendre transformation, and Legendre transformations do not act in the equilibrium space, it is necessary to introduce an auxiliary space to correctly handle the Legendre transformations.
 This is the so-called thermodynamic phase space.
 If the phase space is equipped with a Legendre invariant Riemannian metric, a smooth map can be introduced that induces a thermodynamic metric in the equilibrium manifold.
 The thermodynamic metric can then be used with different thermodynamic potentials without changing the geometric properties of the equilibrium manifold.
 One expects the geometric properties of the equilibrium manifold to be related to the macroscopic physical properties.
 The details of this relation can be summarized in three main points:
The Clausius–Mossotti relation expresses the dielectric constant (relative permittivity) ε of a material in terms of the atomic polarizibility α of the material's constituent atoms and/or molecules, or a homogeneous mixture thereof.
 It is named after Ottaviano-Fabrizio Mossotti and Rudolf Clausius.
 It is equivalent to the Lorentz–Lorenz equation.
 It may be expressed as:
Rudolf Julius Emanuel Clausius (2 January 1822 – 24 August 1888) was a German physicist and mathematician and is considered one of the central founders of the science of thermodynamics.
 By his restatement of Sadi Carnot's principle known as the Carnot cycle, he gave the theory of heat a truer and sounder basis.
 His most important paper, "On the Moving Force of Heat", published in 1850, first stated the basic ideas of the second law of thermodynamics.
 In 1865 he introduced the concept of entropy.
 In 1870 he introduced the virial theorem which applied to heat.
Sergey Vasilyevich Kravkov (Russian: Сергей Вaсильевич Кравков; 1893–1951) was a Russian psychologist and psychophysiologist, Doctor of Science in Biology (1935), Corresponding Member of the Academy of Science of the USSR and the Academy of Medical Science of the USSR (1946).
 He is considered one of the founders of physiological optics, a scientific discipline that studies physiological processes, physical and psychic regularities which characterize the functioning of organs of human vision.
Ferdinand de Saussure ( ; ] ; 26 November 1857 – 22 February 1913) was a Swiss linguist and semiotician.
 His ideas laid a foundation for many significant developments in both linguistics and semiology in the 20th century.
 He is widely considered one of the founders of 20th-century linguistics and one of two major founders (together with Charles Sanders Peirce) of semiotics/semiology.
