An endolith or endolithic is an organism that is able to acquire the necessary resources for growth in the inner part of a rock, mineral, coral, animal shells, or in the pores between mineral grains of a rock. Many are extremophiles, living in places long considered inhospitable to life. The distribution, biomass, and diversity of endolith microorganisms are determined by the physical and chemical properties of the rock substrate, including the mineral composition, permeability, the presence of organic compounds, the structure and distribution of pores, water retention capacity, and the pH. Normally, the endoliths colonize the areas within lithic substrates to withstand intense solar radiation, temperature fluctuations, wind, and desiccation. They are of particular interest to astrobiologists, who theorize that endolithic environments on Mars and other planets constitute potential refugia for extraterrestrial microbial communities.
Friedman, Friedmann, and Freedman are surnames of German origin, and from the 17th century were also adopted by Ashkenazi Jews. It is the 9th most common surname in Israel and most common exclusively Ashkenazi name. They may refer to:
The Friedmann–Lemaître–Robertson–Walker metric is a metric based on an exact solution of the Einstein field equations of general relativity. The metric describes a homogeneous, isotropic, expanding universe that is path-connected, but not necessarily simply connected. The general form of the metric follows from the geometric properties of homogeneity and isotropy; Einstein's field equations are only needed to derive the scale factor of the universe as a function of time. Depending on geographical or historical preferences, the set of the four scientists – Alexander Friedmann, Georges Lemaître, Howard P. Robertson and Arthur Geoffrey Walker – are variously grouped as Friedmann, Friedmann–Robertson–Walker (FRW), Robertson–Walker (RW), or Friedmann–Lemaître (FL). This model is sometimes called the Standard Model of modern cosmology, although such a description is also associated with the further developed Lambda-CDM model. The FLRW model was developed independently by the named authors in the 1920s and 1930s.
Alexander Alexandrovich Friedmann was a Russian and Soviet physicist and mathematician. He originated the pioneering theory that the universe is expanding, governed by a set of equations he developed known as the Friedmann equations.
The Lahore Ahmadiyya Movement for the Propagation of Islam, is a separatist group within the Ahmadiyya movement that formed in 1914 as a result of ideological and administrative differences following the demise of Hakim Nur-ud-Din, the first Caliph after Mirza Ghulam Ahmad. Members of the Lahore Ahmadiyya movement are referred to by the majority group as ghayr mubāyi'īn and are also known colloquially as Lahori Ahmadis.
The Friedmann equations, also known as the Friedmann–Lemaître (FL) equations, are a set of equations in physical cosmology that govern cosmic expansion in homogeneous and isotropic models of the universe within the context of general relativity. They were first derived by Alexander Friedmann in 1922 from Einstein's field equations of gravitation for the Friedmann–Lemaître–Robertson–Walker metric and a perfect fluid with a given mass density ρ and pressure p. The equations for negative spatial curvature were given by Friedmann in 1924.
Meir Friedmann was an Austrian-Hungarian Jewish scholar. His editions of the Midrash are the standard texts. His chief editions were the Sifre (1864), the Mekhilta (1870), Pesiqta Rabbathi (1880). At the time of his death he was editing the Sifra. Friedmann, while inspired with regard for tradition, dealt with the Rabbinic texts with modern scientific methods, and rendered conspicuous service to the critical investigation of the Midrash and to the history of early homilies.
Georges Philippe Friedmann, was a French sociologist and philosopher, known for his influential work on the effects of industrial labor on individuals and his criticisms of the uncontrolled embrace of technological change in twentieth-century Europe and the United States.
Bernhard Friedmann was a German economist and politician of the Christian Democratic Union of Germany.
Adolph Hermann Friedmann was a German philosopher and jurist, Finnish citizen from 1906. In Finland Friedmann became known to the general public as a lawyer. His most famous case was a murder committed in 1927 in Turku. Friedmann defended the head of the University Library of Åbo Akademi and his wife in a murder trial, which was extensively reported in the newspapers around Europe.
