Scientific method

Scientific method
Diagram illustrating steps in the scientific method. The scientific method is an ongoing process, which usually begins with observations about the natural world. Human beings are naturally inquisitive, so they often come up with questions about things they see or hear and often develop ideas (hypotheses) about why things are the way they are. The best hypotheses lead to predictions that can be tested in various ways, including making further observations about nature. In general, the strongest tests of hypotheses come from carefully controlled and replicated experiments that gather empirical data. Depending on how well the tests match the predictions, the original hypothesis may require refinement, alteration, expansion or even rejection. Although procedures vary from one field of inquiry to another, identifiable features are frequently shared in common between them.

philosophy bites Thought experiment A thought experiment or Gedankenexperiment (from German) considers some hypothesis, theory,[1] or principle for the purpose of thinking through its consequences. Given the structure of the experiment, it may or may not be possible to actually perform it, and if it can be performed, there need be no intention of any kind to actually perform the experiment in question. The common goal of a thought experiment is to explore the potential consequences of the principle in question: "A thought experiment is a device with which one performs an intentional, structured process of intellectual deliberation in order to speculate, within a specifiable problem domain, about potential consequents (or antecedents) for a designated antecedent (or consequent)" (Yeates, 2004, p. 150). Overview[edit] Salviati. Although the extract does not convey the elegance and power of the 'demonstration' terribly well, it is clear that it is a 'thought' experiment, rather than a practical one. Variety[edit] Uses[edit]

Hypothesis A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research.[1] The adjective hypothetical, meaning "having the nature of a hypothesis", or "being assumed to exist as an immediate consequence of a hypothesis", can refer to any of these meanings of the term "hypothesis". Uses[edit] In Plato's Meno (86e–87b), Socrates dissects virtue with a method used by mathematicians,[2] that of "investigating from a hypothesis Scientific hypothesis[edit] Working hypothesis[edit] See also[edit] Notes[edit]

Saint, Peace Seeker, Hero by Turns HODAL, India — Barreling down a sizzling-hot road, in a cloud of diesel fumes and dust, Ludkan Baba is on a serious roll. He lies flat on the ground, turning himself over and over like a runaway log, limbs flailing as he bumps across potholes, splashes through mud puddles and falls deeper into a spiritual trance. Like any sadhu, or Hindu ascetic, he undertakes severe penance to liberate his soul from reincarnation's endless cycle of birth, death and rebirth. Stretched out in the middle of the road, rolling hour after hour, mile after mile through crowds and heavy traffic, he is making his trip to eternal bliss. But this is no ordinary holy roller. He has rolled thousands of miles in the last 19 years, turning round and round so many millions of times that just pondering the thought can make your head spin. Yet to the 55-year-old sadhu, the constant turning is refreshing. "I move during cyclones, during blazing summers and cold winters," he said. He believes God's hand propels him.

Occam's razor The sun, moon and other solar system planets can be described as revolving around the Earth. However that explanation's ideological and complex assumptions are completely unfounded compared to the modern consensus that all solar system planets revolve around the Sun. Ockham's razor (also written as Occam's razor and in Latin lex parsimoniae) is a principle of parsimony, economy, or succinctness used in problem-solving devised by William of Ockham (c. 1287 - 1347). Solomonoff's theory of inductive inference is a mathematically formalized Occam's Razor:[2][3][4][5][6][7] shorter computable theories have more weight when calculating the probability of the next observation, using all computable theories which perfectly describe previous observations. History[edit] Formulations before Ockham[edit] Part of a page from Duns Scotus' book Ordinatio: "Pluralitas non est ponenda sine necessitate", i.e., "Plurality is not to be posited without necessity" Ockham[edit] Later formulations[edit]

Forming Research Questions and Identifying Key Concepts View Worksheet After you have chosen a research paper topic, developing research questions and identifying key concepts helps you write a strong thesis statement and conduct structured research. Jumping into your topic without asking the right questions and developing a plan hurts the overall strength of your paper. In addition, by developing questions and identifying concepts, you make it easier to determine what information you need and how that information pertains to the scope of your research paper. Forming research questions to shape your thesis statement Forming research questions is essential in writing an effective thesis statement.

Meta-analysis In statistics, meta-analysis comprises statistical methods for contrasting and combining results from different studies, in the hope of identifying patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light in the context of multiple studies.[1] Meta-analysis can be thought of as "conducting research about previous research." In its simplest form, meta-analysis is done by identifying a common statistical measure that is shared between studies, such as effect size or p-value, and calculating a weighted average of that common measure. This weighting is usually related to the sample sizes of the individual studies, although it can also include other factors, such as study quality. The motivation of a meta-analysis is to aggregate information in order to achieve a higher statistical power for the measure of interest, as opposed to a less precise measure derived from a single study.

Critical thinking | Learning resources Advice and resources on the subject of critical thinking. Why is being critical important? It affects your academic success: if you wish to achieve higher grades, being able to take an informed and analytical approach to your studies is very important. Simply memorising and explaining concepts and ideas will not be sufficient for a strong pass at masters level. It affects your employability: one of the main reasons students undertake postgraduate study is to improve their employment prospects. What do we mean by ‘critical’? Being ‘critical’ does not mean just being negative, or pointing out what is wrong about something. You can find out more about the framework at : SCQF level descriptors (PDF) Taking a critical approach in your studies and professional development can include behaviours such as: You can find out more about being critical in your studies in the following factsheets: Critical thinking ‘stairway’ Critical thinking: online guidance from the Open University Further reading

Models of scientific inquiry In the philosophy of science, models of scientific inquiry have two functions: first, to provide a descriptive account of how scientific inquiry is carried out in practice, and second, to provide an explanatory account of why scientific inquiry succeeds as well as it appears to do in arriving at genuine knowledge. The search for scientific knowledge extends far back into antiquity. At some point in the past, at least by the time of Aristotle, philosophers recognized that a fundamental distinction should be drawn between two kinds of scientific knowledge — roughly, knowledge that and knowledge why. It is one thing to know that each planet periodically reverses the direction of its motion with respect to the background of fixed stars; it is quite a different matter to know why. Accounts of scientific inquiry[edit] Classical model[edit] Pragmatic model[edit] Logical empiricism[edit] Not all explanations in science are of the D-N type, however. Choice of a theory[edit] See also[edit]

Philosophy of science Philosophy of science is a branch of philosophy concerned with the foundations, methods, and implications of science. The central questions concern what counts as science, the reliability of scientific theories, and the purpose of science. This discipline overlaps with metaphysics, ontology and epistemology, for example, when it explores the relationship between science and truth. While the relevant history of philosophy dates back at least to Aristotle, philosophy of science emerged as a distinct discipline only in the middle of the 20th century in the wake of logical positivism, a movement that aimed to formulate criteria to ensure all philosophical statements' meaningfulness and objectively assess them. Today, some thinkers seek to ground science in axiomatic assumptions such as the uniformity of nature. Introduction[edit] Defining science[edit] Karl Popper c. 1980s Distinguishing between science and non-science is referred to as the demarcation problem. Scientific explanation[edit]

The Deconstruction of Reality: Modernism and Postmodernism by Ken Sanes Modernism Modern philosophy and science are based on the idea that the world of appearances is an illusion that both reveals and conceals an underlying reality. In many instances, this idea has also been attached to mystical systems of thought, as in some Eastern philosophies that view reality as a play of fictions manifested by a universal mind. In the West, it has been the intellectual undergirding for rationalism and empiricism, which have given rise to modern science and social science. Today, not surprisingly, this idea is the dominant element in most fields of thought. In the natural sciences, physics views the materiality of the world as a kind of mirage and describes microscopic and macroscopic realms in which nature loses many of the characteristics it has in the Newtonian world of everyday existence. In effect, these philosophies and disciplines assert that matter, life, society, cultural creations and mind aren't what they appear to be. Postmodernism One note.
