all about science

Scientists learn about their subject by observing, describing, and experimenting. [j] The philosopher of science Karl Popper sharply distinguished truth from certainty. [102] Theories vary in the extent to which they have been tested and verified, as well as their acceptance in the scientific community. "—, "No amount of experimentation can ever prove me right; a single experiment can prove me wrong." Aristotle maintained that man knows a thing scientifically "when he possesses a conviction arrived at in a certain way, and when the first principles on which that conviction rests are known to him with certainty".[49]. "[12] This should not be confused with the word statistic, referring to a quantity (such as mean or median) calculated from a set of data,[13] whose plural is statistics ("this statistic seems wrong" or "these statistics are misleading"). [174] Examples of issues that have involved the politicization of science include the global warming controversy, health effects of pesticides, and health effects of tobacco. The term does not yet have a well-established, precise meaning, but systems theory can reasonably be considered a specialization of systems thinking and a generalization of systems science. Many factors can act as facets of the politicization of science such as populist anti-intellectualism, perceived threats to religious beliefs, postmodernist subjectivism, and fear for business interests. The Greek astronomer Aristarchus of Samos (310–230 BCE) was the first to propose a heliocentric model of the universe, with the Sun at the center and all the planets orbiting it. [102] While there are such famous cases as the theory of relativity that required a complete reconceptualization, these are extreme exceptions. Because of the collapse of the Western Roman Empire due to the Migration Period an intellectual decline took place in the western part of Europe in the 400s. [173] Tactics such as shifting conversation, failing to acknowledge facts, and capitalizing on doubt of scientific consensus have been used to gain more attention for views that have been undermined by scientific evidence. [m] Physicist Richard Feynman coined the term "cargo cult science" for cases in which researchers believe they are doing science because their activities have the outward appearance of science but actually lack the "kind of utter honesty" that allows their results to be rigorously evaluated. [32] Despite the complexity of the science, certain unifying concepts consolidate it into a single, coherent field. Modern natural science is the successor to the natural philosophy that began in Ancient Greece. During late antiquity, in the Byzantine empire many Greek classical texts were preserved. In 1981, one estimate for the number of scientific and technical journals in publication was 11,500. Science is actually all these things . [5][6] 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[7] but was preserved in the Muslim world during the Islamic Golden Age. In general, a science involves a pursuit of knowledge covering general truths or the operations of fundamental laws. [75][77]:102 Kepler modelled the eye as a water-filled glass sphere with an aperture in front of it to model the entrance pupil. Science can take your mind off of things. [80] It is during this period that the word "science" gradually became more commonly used to refer to a type of pursuit of a type of knowledge, especially knowledge of nature – coming close in meaning to the old term "natural philosophy. So come and find out answers to the unique questions only with All About Science In this respect, the lessons of history and the social structures built upon it could be discarded. When a hypothesis proves unsatisfactory, it is either modified or discarded. [135] He held that the successful sciences trust not to any single chain of inference (no stronger than its weakest link) but to the cable of multiple and various arguments intimately connected.[136]. Decision theory (or the theory of choice not to be confused with choice theory) is the study of an agent's choices. He characterized normal science as the process of observation and "puzzle solving" which takes place within a paradigm, whereas revolutionary science occurs when one paradigm overtakes another in a paradigm shift. [46] Socrates criticized the older type of study of physics as too purely speculative and lacking in self-criticism. ", "Chronicle for Societies Founded from 1323 to 1599", "The Environmental Studies Association of Canada - What is a Learned Society? the relations that lead to the acceptance of one proposition (the conclusion) on the basis of a set of other propositions (premises). [73] One prominent scientist in this era was Roger Bacon. This is especially the case in the more macroscopic fields of science (e.g. In Northern Europe, the new technology of the printing press was widely used to publish many arguments, including some that disagreed widely with contemporary ideas of nature. They both make teaching Zoology (/zoʊˈɒlədʒi/)[note 7] is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.

[60][a] In addition, the neighboring Sassanid Empire established the medical Academy of Gondeshapur where Greek, Syriac, and Persian physicians established the most important medical center of the ancient world during the 6th and 7th centuries. Space telescopes lead to numerous discoveries in astronomy and cosmology. These images all show an aspect of science, but a complete view of science is more than any particular instance. In that vein, theories are formulated according to most of the same scientific principles as hypotheses. [114] Ziman shows how scientists can identify patterns to each other across centuries; he refers to this ability as "perceptual consensibility. Harmful environmental issues such as ozone depletion, acidification, eutrophication and climate change came to the public's attention in the same period, and caused the onset of environmental science and environmental technology.

[108][109] This can be achieved by careful experimental design, transparency, and a thorough peer review process of the experimental results as well as any conclusions. According to the Society for Industrial and Applied Mathematics, computation is now as important as theory and experiment in advancing scientific knowledge.[117]. The Socratics also insisted that philosophy should be used to consider the practical question of the best way to live for a human being (a study Aristotle divided into ethics and political philosophy). New ideas in physics often explain the fundamental mechanisms of other sciences, while opening to new research areas in mathematics and philosophy. Here we go… The main objective of this article is to derive a new set of gravitational field equations and to establish a new unified theory for dark energy and dark matter. [103] An explanatory thought experiment or hypothesis is put forward as explanation using principles such as parsimony (also known as "Occam's Razor") and are generally expected to seek consilience – fitting well with other accepted facts related to the phenomena. "Decision theory: A brief introduction." Natural science can be divided into two main branches: life science and physical science. Living organisms are open systems that survive by transforming energy and decreasing their local entropy[33] to maintain a stable and vital condition defined as homeostasis.[34]. It has many branches that include, but are not limited to, anthropology, archaeology, communication studies, economics, history, human geography, jurisprudence, linguistics, political science, psychology, public health, and sociology. About. Work in this field is often distinguished by its emphasis on mathematical technique and rigor. Instead, supernatural explanations should be left a matter of personal belief outside the scope of science. In Bacon's words, "the real and legitimate goal of sciences is the endowment of human life with new inventions and riches", and he discouraged scientists from pursuing intangible philosophical or spiritual ideas, which he believed contributed little to human happiness beyond "the fume of subtle, sublime, or pleasing speculation".[81]. Kepler did not reject Aristotelian metaphysics and described his work as a search for the Harmony of the Spheres.
