Scientific Method

The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least in the 17th century. It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypothesis, via induction, based on such observations; experimental and measurement-based testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises.

Though diverse models for scientific model are available, there is in general a continuous process that includes observation about the natural world. People are naturally inquisitive, so they often come up with questions about they see or hear, and they often develop ideas or hypotheses about why things are the way they are. The best hypotheses lead to predictions that can be tested in various ways. The most conclusive testing of hypotheses comes from reasoning based on carefully controlled experimental data. Depending on how well additional tests match the predictions, the original hypothesis may require refinement, alteration, expansion, or even rejection. If a particular hypothesis becomes very well supported, a general theory may be developed.

Although procedures vary from one field of study to another, they are frequently the same from one to another. The process of the scientific method involves making conjectures (or hypotheses), deriving predictions from them as logical consequences, and then carrying out experiments or empirical observations based on those predictions. A hypothesis is a conjecture, based on knowledge obtained while seeking answers to the question. The hypothesis might be very specific, or it might be broad. Scientists then test hypotheses by conducting experiments or studies. A scientific hypothesis must be falsifiable, implying that it is possible to identify a possible outcome of the experiment or observation that conflicts with predictions deduced from the hypothesis; otherwise, the hypothesis cannot be meaningfully tested.

The purpose of an experiment is to determibe whether observations agree with or conflict with the predictions derived from the hypothesis. Experiments can take place anywhere. There are difficulties in a formulaic statement of method, however. Though the scientific method is often presented as a fixed sequence of steps, it rather presents a set of general principles. Not all steps take place in every scientific inquiry, (nor to the same degree), and they are not always in the same order.

Joint Meetings of the Australian Parliament

A joint meeting of the Australian Parliament is a convening of members of the Senate and House of Representatives sitting together as a single legislative body. Australia has a bicameral federal Parliament, consisting of the Senate and House of Representatives. Subject to the Constitution of Australia, each House has its own rules, standing orders and procedures, its own presiding officer, and meets separately, at dates and times it alone decides. However, there are some occasions when the two Houses have come together as a single body. Unlike the Opening of Parliament which is officially made by the Governor-General at the Senate premises, the joint sessions are held at the House of Representatives chamber. The reasons of joint meetings have included: To resolve deadlocks between the Houses following the trigger of a double dissolution To fill casual vacancies in the representation of the territories in the Senate A special commemorative joint sitting to Celebrate the Centenary o...

Our Lady of Peace and Good Voyage

Our Lady of Peace and Good Voyage or the Virgin of Antipolo is a seventeenth century Roman Catholic wooden image of the Blessed Virgin Mary as venerated in the Philippines. This Black Madonna is enshrined in Antipolo Cathedral in the Sierra Madre mountains east of Metro Manila. The image was brought to the country by Governor-General Juan Niño de Tabora from Mexico via the galleon El Almirante in 1626. His safe voyage across the Pacific Ocean was attributed to the image, which was then given the title "Our Lady of Peace and Good Voyage." It was substantiated later by six other successful voyages of the Manila-Acapulco Galleons witb the image aboard as its patroness. Pope Pius XI issued a Pontifical decree to crown the image in 1925. The statue is one of the most celebrated Marian images in the Philippines, having mentioned by national martyr Jose Rizal in his writings. From May to July each year, the image attracts millions of pilgrims from all over the country and abroad. ...

How to Create a Richly Imagined World

For someone who likes fantasy and sci-fi fiction, most of the time, a lot of people ask me about how to create a richly imagined world. Fantasy and sci-fi elements rest heavily on how an author weave the setting and the world in which the heroes dwell in, and it helps to make the novel to be imagined vividly in the readers' minds. A convincing world should be relatable, something that we can associate ourselves with. For us to be associated with a world an author created in his mind, and wrote on the pages of a book, this world has to be close to the real thing. It has to be systematic, real and alive, and very convincing. A real world has certain elements, and an author must consider them in writing a vividly imagined world: Cartography - a fantasy or sci-fi world depend heavily on geography and maps, especially if the plot requires war and the belligerents occupy so much space in the plot. A convincing world has the world separated in territories, and every part of the...
