Paul Alfred Weiss
Paul Alfred Weiss (March 21, 1898 – September 8, 1989) was an Austrian biologist who specialised in morphogenesis, development, differentiation and neurobiology. A teacher, experimenter and theorist, he made a lasting contribution to science in his lengthy career, throughout which he sought to encourage specialists in different fields to meet and share insights. Paul Weiss was born in Vienna, the son of a Jewish couple, Carl S. Weiss, a businessman, and Rosalie Kohn Weiss. His background favoured music, poetry, and philosophy – Weiss himself was a violinist – but an uncle encouraged an interest in science. Weiss received his baccalaureate in 1916. After the end of the First World War, having served for three years as an officer in the artillery, he commenced studies in mechanical engineering at the Technische Hochschule in Vienna, (now Vienna University of Technology). He then shifted his focus to biology with a minor in physics. He absorbed the studies of Edmond B. Wilso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Morphogenetic Fields
In the developmental biology of the early twentieth century, a morphogenetic field is a group of cells able to respond to discrete, localized biochemical signals leading to the development of specific morphological structures or organs. The spatial and temporal extents of the embryonic field are dynamic, and within the field is a collection of interacting cells out of which a particular organ is formed. As a group, the cells within a given morphogenetic field are constrained: thus, cells in a ''limb field'' will become a limb tissue, those in a ''cardiac field'' will become heart tissue. However, specific cellular programming of individual cells in a field is flexible: an individual cell in a cardiac field can be redirected via cell-to-cell signaling to replace specific damaged or missing cells. Imaginal discs in insect larvae are examples of morphogenetic fields. Historical development The concept of the morphogenetic field, fundamental in the early twentieth century to the ...

Organicism
Organicism is the philosophical position that states that the universe and its various parts (including human societies) ought to be considered alive and naturally ordered, much like a living organism.Gilbert, S. F., and S. Sarkar. 2000. "Embracing Complexity: Organicism for the 21st Century." ''Develop Dynam'' 219: 1–9. Vital to the position is the idea that organicistic elements are not dormant "things" ''per se'' but rather dynamic components in a comprehensive system that is, as a whole, everchanging. Organicism is related to but remains distinct from holism insofar as it prefigures holism; while the latter concept is applied more broadly to universal part-whole interconnections such as in anthropology and sociology, the former is traditionally applied only in philosophy and biology. Furthermore, organicism is incongruous with reductionism because of organicism's consideration of "both bottom-up and top-down causation." Regarded as a fundamental tenet in natural philosophy, o ...

Determinism
Determinism is a philosophical view, where all events are determined completely by previously existing causes. Deterministic theories throughout the history of philosophy have developed from diverse and sometimes overlapping motives and considerations. The opposite of determinism is some kind of indeterminism (otherwise called nondeterminism) or randomness. Determinism is often contrasted with free will, although some philosophers claim that the two are compatible.For example, see Determinism is often used to mean ''causal determinism'', which in physics is known as cause-and-effect. This is the concept that events within a given paradigm are bound by causality in such a way that any state of an object or event is completely determined by its prior states. This meaning can be distinguished from other varieties of determinism mentioned below. Debates about determinism often concern the scope of determined systems; some maintain that the entire universe is a single determina ...

Mechanicism
The mechanical philosophy is a form of natural philosophy which compares the universe to a large-scale mechanism (i.e. a machine). The mechanical philosophy is associated with the scientific revolution of early modern Europe. One of the first expositions of universal mechanism is found in the opening passages of ''Leviathan'' by Thomas Hobbes, published in 1651. Some intellectual historians and critical theorists argue that early mechanical philosophy was tied to disenchantment and the rejection of the idea of nature as living or animated by spirits or angels. Other scholars, however, have noted that early mechanical philosophers nevertheless believed in magic, Christianity and spiritualism. Mechanism and determinism Some ancient philosophies held that the universe is reducible to completely mechanical principles—that is, the motion and collision of matter. This view was closely linked with materialism and reductionism, especially that of the atomists and to a large extent, sto ...

Reductionism
Reductionism is any of several related philosophical ideas regarding the associations between phenomena which can be described in terms of other simpler or more fundamental phenomena. It is also described as an intellectual and philosophical position that interprets a complex system as the sum of its parts. Definitions ''The Oxford Companion to Philosophy'' suggests that reductionism is "one of the most used and abused terms in the philosophical lexicon" and suggests a three-part division: # Ontological reductionism: a belief that the whole of reality consists of a minimal number of parts. # Methodological reductionism: the scientific attempt to provide an explanation in terms of ever-smaller entities. # Theory reductionism: the suggestion that a newer theory does not replace or absorb an older one, but reduces it to more basic terms. Theory reduction itself is divisible into three parts: translation, derivation, and explanation. Reductionism can be applied to any phenomenon, ...

Systems Biology
Systems biology is the computational modeling, computational and mathematical analysis and modeling of complex biological systems. It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach (holism instead of the more traditional reductionist, reductionism) to biological research. Particularly from the year 2000 onwards, the concept has been used widely in biology in a variety of contexts. The Human Genome Project is an example of applied systems thinking in biology which has led to new, collaborative ways of working on problems in the biological field of genetics. One of the aims of systems biology is to model and discover emergent property, emergent properties, properties of cell (biology), cells, tissue (biology), tissues and organisms functioning as a system whose theoretical description is only possible using techniques of systems biology. These typically involve metabolic networks or cell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Von Bertalanffy
Karl Ludwig von Bertalanffy (19 September 1901 – 12 June 1972) was an Austrian biologist known as one of the founders of general systems theory (GST). This is an interdisciplinary practice that describes systems with interacting components, applicable to biology, cybernetics and other fields. Bertalanffy proposed that the classical laws of thermodynamics might be applied to closed systems, but not necessarily to "open systems" such as living things. His mathematical model of an organism's growth over time, published in 1934, is still in use today. Bertalanffy grew up in Austria and subsequently worked in Vienna, London, Canada, and the United States. Biography Ludwig von Bertalanffy was born and grew up in the little village of Atzgersdorf (now Liesing) near Vienna. The Bertalanffy family had roots in the 16th century nobility of Hungary which included several scholars and court officials.T.E. Weckowicz (1989).

James Earl Carter Jr. (born October 1, 1924) is an American politician who served as the 39th president of the United States from 1977 to 1981. A member of the Democratic Party (United States), Democratic Party, he previously served as the 76th governor of Georgia from 1971 to 1975 and as a Georgia state senator from 1963 to 1967. Since leaving office, Carter has remained engaged in political and social projects, receiving the Nobel Peace Prize in 2002 for his humanitarian work. Born and raised in Plains, Georgia, Carter graduated from the United States Naval Academy in 1946 with a Bachelor of Science degree and joined the United States Navy, serving on numerous submarines. After the death of his father in 1953, he left his naval career and returned home to Plains, where he assumed control of his family's peanut-growing business. He inherited little, due to his father's forgiveness of debts and the division of the estate amongst himself and his siblings. Nevertheless, his ...

Yale
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
