Scientific Demonstration
A scientific demonstration is a procedure carried out for the purposes of demonstrating scientific principles, rather than for hypothesis testing or knowledge gathering (although they may originally have been carried out for these purposes). Most scientific demonstrations are simple laboratory demonstrations intended to demonstrate physical principles, often in a surprising or entertaining way. They are carried out in schools and universities, and sometimes in public demonstrations in popular science lectures and TV programs aimed at the public. Many scientific demonstrations are chosen for their combination of educational merit and entertainment value, which is often provided by dramatic phenomena such as explosions. Public scientific demonstrations were a common occurrence in the Age of Enlightenment, and have long been a feature of the British Royal Institution Christmas Lectures, which date back to 1825. In the television era, scientific demonstrations have featured in scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypothesis Testing
A statistical hypothesis test is a method of statistical inference used to decide whether the data provide sufficient evidence to reject a particular hypothesis. A statistical hypothesis test typically involves a calculation of a test statistic. Then a decision is made, either by comparing the test statistic to a critical value or equivalently by evaluating a ''p''-value computed from the test statistic. Roughly 100 specialized statistical tests are in use and noteworthy. History While hypothesis testing was popularized early in the 20th century, early forms were used in the 1700s. The first use is credited to John Arbuthnot (1710), followed by Pierre-Simon Laplace (1770s), in analyzing the human sex ratio at birth; see . Choice of null hypothesis Paul Meehl has argued that the epistemological importance of the choice of null hypothesis has gone largely unacknowledged. When the null hypothesis is predicted by theory, a more precise experiment will be a more severe test of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Age Of Enlightenment
The Age of Enlightenment (also the Age of Reason and the Enlightenment) was a Europe, European Intellect, intellectual and Philosophy, philosophical movement active from the late 17th to early 19th century. Chiefly valuing knowledge gained through rationalism and empiricism, the Enlightenment was concerned with a wide range of social and Politics, political ideals such as natural law, liberty, and progress, toleration and fraternity (philosophy), fraternity, constitutional government, and the formal separation of church and state. The Enlightenment was preceded by and overlapped the Scientific Revolution, which included the work of Johannes Kepler, Galileo Galilei, Francis Bacon, Pierre Gassendi, Christiaan Huygens and Isaac Newton, among others, as well as the philosophy of Descartes, Hobbes, Spinoza, Leibniz, and John Locke. The dating of the period of the beginning of the Enlightenment can be attributed to the publication of René Descartes' ''Discourse on the Method'' in 1 ...

Royal Institution Christmas Lectures
The Royal Institution Christmas Lectures are a series of lectures on a single topic each, which have been held at the Royal Institution in London each year since 1825. The lectures present scientific subjects to a general audience, including young people, in an informative and entertaining manner. Michael Faraday conceived and initiated the Christmas Lecture series in 1825, at a time when organised education for young people was scarce. Many of the Christmas Lectures were published. History The Royal Institution's Christmas Lectures were first held in 1825, and have continued on an annual basis since then except for four years during the Second World War. They have been hosted each year at the Royal Institution itself, except in 1929 and between 2005 and 2006, each time due to refurbishment of the building. They were created by Michael Faraday, who later hosted the lecture season on nineteen occasions. The Nobel laureate Sir William Bragg gave the Christmas lectures on four ...

MythBusters
''MythBusters'' is a science entertainment television series created by Peter Rees (producer), Peter Rees and produced by Beyond International in Australia. The series premiered on the Discovery Channel on January 23, 2003. It was broadcast internationally by many television networks and other Discovery channels worldwide. The show's original hosts, special effects experts Adam Savage and Jamie Hyneman, used elements of the scientific method to Debunker, test the validity of rumors, myths, movie scenes, adages, Internet videos, and news stories. Filmed in San Francisco and edited in Artarmon, Sydney, ''MythBusters'' aired 282 total episodes before its cancellation at the end of the MythBusters (2016 season), 2016 season in March. Planning and some experimentation took place at Hyneman's workshops in San Francisco; experiments requiring more space or special accommodations were filmed on location, typically around the San Francisco Bay Area and other locations in Northern Califo ...

Science Abuse
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Greek natural philo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demonstration (teaching)
Demonstration involves showing by reason or proof, explaining or making clear by use of examples or experiments. Put more simply, demonstration means 'to clearly show'.yourdictionary.com.''Demonstrating Definition''. http://www.yourdictionary.com/demonstrating. Overview In teaching through demonstration, students are set up to potentially conceptualize class material more effectively as shown in a study which specifically focuses on chemistry demonstrations presented by teachers.McKee, Erik, Vickie M. Williamson, and Laura E. Ruebush. "Effects of Demonstration Laboratory on Student Learning". ''Journal of Science Education and Technology''. 16.5 (2007) 395-400. Demonstrations often occur when students have a hard time connecting theories to actual practice or when students are unable to understand application of theories.

Science In The Age Of Enlightenment
The history of science during the Age of Enlightenment traces developments in science and technology during the Age of Enlightenment, Age of Reason, when Enlightenment ideas and ideals were being disseminated across Europe and North America. Generally, the period spans from the final days of the 16th- and 17th-century Scientific Revolution until roughly the 19th century, after the French Revolution (1789) and the Napoleonic era (1799–1815). The scientific revolution saw the creation of the first Learned society, scientific societies, the rise of Heliocentrism, Copernicanism, and the displacement of Aristotelianism, Aristotelian natural philosophy and Galen's ancient medical doctrine. By the 18th century, scientific authority began to displace religious authority, and the disciplines of alchemy and astrology lost scientific credibility. While the Enlightenment cannot be pigeonholed into a specific doctrine or set of dogmas, science came to play a leading role in Enlightenment dis ...

Technology Demonstration
A technology demonstration (or tech demo), also known as demonstrator model, is a prototype, rough example or otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users. Computers and gaming Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles in software and hardware development. * Computer game developers use tech demos to rouse and maintain interest to titles still in development (because game engines are usually ready before the art is finished) and to ensure functionality by early testing.

Science Education
Science education is the teaching and learning of science to school children, college students, or adults within the general public. The field of science education includes work in science content, science process (the scientific method), some social science, and some teaching pedagogy. The standards for science education provide expectations for the development of understanding for students through the entire course of their K–12 (education), K-12 education and beyond. The traditional subjects included in the standards are Physical science, physical, Life science, life, Earth science, earth, space science, space, and human sciences. Historical background The first person credited with being employed as a science teacher in a British public school (privately funded), public school was William Sharp (homeopath), William Sharp, who left the job at Rugby School in 1850 after establishing science to the curriculum. Sharp is said to have established a model for science to be taug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
