Erkki Hartikainen
__NOTOC__ Erkki Juhani Hartikainen (24 June 1942, in Finland – 11 July 2021) was the chairman of ''Atheist Association of Finland'' ("Suomen Ateistiyhdistys" in Finnish, an atheistic association in Finland). He qualified for a Master of Science in the University of Helsinki in 1967. His subjects were mathematics, theoretical philosophy and computer science. Hartikainen has been the chairman of Atheist Association of Finland since 1985. Hartikainen has served as the actuary since the late 1960s, for nearly 20 years as a teacher of mathematics and science in schools, and after that, since 1989, as teacher of information technology at a college in Vantaa. From 1994–1998, he worked as a statistician in Vantaa. Hartikainen retired in 2005.

He was one of the leading atheist freethinkers in F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Atheists
American Atheists is a non-profit organization in the United States dedicated to defending the civil liberties of atheists and advocating complete separation of church and state. It provides speakers for colleges, universities, clubs, and the news media. It also publishes books and ''American Atheist Magazine''. The organization was founded in 1963 by Madalyn Murray O'Hair. She had earlier filed a lawsuit against her school board, with her son William J. Murray as plaintiff, to challenge compulsory prayer and Bible-reading in public schools. Her case, ''Murray v. Curlett'', was consolidated with ''Abington School District v. Schempp'' before being heard by the United States Supreme Court. In 1963, it ruled that mandatory Bible reading in public schools was unconstitutional. History Origin and early legal action American Atheists was founded in 1963 by Madalyn Murray O'Hair as the Society of Separationists, after the legal cases ''Abington School District v. Schempp'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thinking
In their most common sense, the terms thought and thinking refer to conscious cognitive processes that can happen independently of sensory stimulation. Their most paradigmatic forms are judging, reasoning, concept formation, problem solving, and deliberation. But other mental processes, like considering an idea, memory, or imagination, are also often included. These processes can happen internally independent of the sensory organs, unlike perception. But when understood in the widest sense, any mental event may be understood as a form of thinking, including perception and unconscious mental processes. In a slightly different sense, the term ''thought'' refers not to the mental processes themselves but to mental states or systems of ideas brought about by these processes. Various theories of thinking have been proposed, some of which aim to capture the characteristic features of thought. ''Platonists'' hold that thinking consists in discerning and inspecting Platonic forms and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classical Electrodynamics
Classical electromagnetism or classical electrodynamics is a branch of theoretical physics that studies the interactions between electric charges and currents using an extension of the classical Newtonian model; It is, therefore, a classical field theory. The theory provides a description of electromagnetic phenomena whenever the relevant length scales and field strengths are large enough that quantum mechanical effects are negligible. For small distances and low field strengths, such interactions are better described by quantum electrodynamics, which is a quantum field theory. Fundamental physical aspects of classical electrodynamics are presented in many texts, such as those by Feynman, Leighton and Sands, Griffiths, Panofsky and Phillips, and Jackson. History The physical phenomena that electromagnetism describes have been studied as separate fields since antiquity. For example, there were many advances in the field of optics centuries before light was understood to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statistical Thermodynamics
In physics, statistical mechanics is a mathematical framework that applies Statistics, statistical methods and probability theory to large assemblies of microscopic entities. It does not assume or postulate any natural laws, but explains the macroscopic behavior of nature from the behavior of such ensembles. Statistical mechanics arose out of the development of classical thermodynamics, a field for which it was successful in explaining macroscopic physical properties—such as temperature, pressure, and heat capacity—in terms of microscopic parameters that fluctuate about average values and are characterized by probability distributions. This established the fields of statistical thermodynamics and statistical physics. The founding of the field of statistical mechanics is generally credited to three physicists: *Ludwig Boltzmann, who developed the fundamental interpretation of entropy in terms of a collection of microstates *James Clerk Maxwell, who developed models of probab ...

Emergence
In philosophy, systems theory, science, and art, emergence occurs when an entity is observed to have properties its parts do not have on their own, properties or behaviors that emerge only when the parts interact in a wider whole. Emergence plays a central role in theories of integrative levels and of complex systems. For instance, the phenomenon of life as studied in biology is an emergent property of chemistry. In philosophy, theories that emphasize emergent properties have been called emergentism. In philosophy Philosophers often understand emergence as a claim about the etiology of a system's properties. An emergent property of a system, in this context, is one that is not a property of any component of that system, but is still a feature of the system as a whole. Nicolai Hartmann (1882–1950), one of the first modern philosophers to write on emergence, termed this a ''categorial novum'' (new category). Definitions This concept of emergence dates from at least the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kari Enqvist
Kari-Pekka Enqvist (born February 16, 1954 in Lahti, Finland) is a professor of cosmology in the Department of Physical Sciences at the University of Helsinki. Enqvist was awarded his PhD in theoretical physics in 1983. Enqvist is the chairman of the scientific advisory board of Skepsis ry (a Finnish sceptics' society) and has written many books that popularize physics. In 1997 Enqvist was granted the Magnus Ehrnrooth Foundation Physics Award for his efforts in particle physics and cosmology Cosmology () is a branch of physics and metaphysics dealing with the nature of the universe. The term ''cosmology'' was first used in English in 1656 in Thomas Blount (lexicographer), Thomas Blount's ''Glossographia'', and in 1731 taken up in .... In 1999, he was awarded the Tieto-Finlandia award, Finland's most significant award for non-fiction, for his book ''Olemisen porteilla ("At the gates of being")''. Enqvist retired from the University of Helsinki in 2019. References Ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

World View
A worldview or world-view or ''Weltanschauung'' is the fundamental cognitive orientation of an individual or society encompassing the whole of the individual's or society's knowledge, culture, and point of view. A worldview can include natural philosophy; fundamental, existential, and normative postulates; or themes, values, emotions, and ethics. Etymology The term ''worldview'' is a calque of the German word ''Weltanschauung'' , composed of '' Welt'' ('world') and '' Anschauung'' ('perception' or 'view'). The German word is also used in English. It is a concept fundamental to German philosophy, especially epistemology and refers to a ''wide world perception''. Additionally, it refers to the framework of ideas and beliefs forming a global description through which an individual, group or culture watches and interprets the world and interacts with it as a social reality. ''Weltanschauung'' and cognitive philosophy Within cognitive philosophy and the cognitive sciences is the G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Reality
Reality is the sum or aggregate of all that is real or existent within a system, as opposed to that which is only imaginary. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown. Philosophical questions about the nature of reality or existence or being are considered under the rubric of ontology, which is a major branch of metaphysics in the Western philosophical tradition. Ontological questions also feature in diverse branches of philosophy, including the philosophy of science, philosophy of religion, philosophy of mathematics, and philosophical logic. These include questions about whether only physical objects are real (i.e., physicalism), whether reality is fundamentally immaterial (e.g. idealism), whether hypothetical unobservable entities posited by scientific theories exist, whether a 'God' exists, whether numbers and other abstract objects exist, and ...

Ontological Materialism
Materialism is a form of philosophical monism which holds matter to be the fundamental substance in nature, and all things, including mental states and consciousness, are results of material interactions. According to philosophical materialism, mind and consciousness are by-products or epiphenomena of material processes (such as the biochemistry of the human brain and nervous system), without which they cannot exist. This concept directly contrasts with idealism, where mind and consciousness are first-order realities to which matter is dependent while material interactions are secondary. Materialism is closely related to physicalism—the view that all that exists is ultimately physical. Philosophical physicalism has evolved from materialism with the theories of the physical sciences to incorporate more sophisticated notions of physicality than mere ordinary matter (e.g. spacetime, physical energies and forces, and dark matter). Thus, the term ''physicalism'' is preferred over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
