Fortune-tellingFortune telling is the practice of predicting information about a person's life. The scope of fortune telling is in principle identical with the practice of divination. The difference is that divination is the term used for predictions considered part of a religious ritual, invoking deities or spirits, while the term fortune telling implies a less serious or formal setting, even one of popular culture, where belief in occult workings behind the prediction is less prominent than the concept of suggestion, spiritual or practical advisory or affirmation.
Flat EarthFlat Earth is an archaic and scientifically disproven conception of the Earth's shape as a plane or disk. Many ancient cultures subscribed to a flat-Earth cosmography. The idea of a spherical Earth appeared in ancient Greek philosophy with Pythagoras (6th century BC). However, most pre-Socratics (6th–5th century BC) retained the flat-Earth model. In the early 4th century BC, Plato wrote about a spherical Earth. By about 330 BC, his former student Aristotle had provided strong empirical evidence for a spherical Earth.
Carl SaganCarl Edward Sagan (ˈseɪɡən; ; November 9, 1934 December 20, 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, science communicator, author, and professor. His best known scientific contribution is his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation.
Fads and Fallacies in the Name of ScienceFads and Fallacies in the Name of Science (1957)—originally published in 1952 as In the Name of Science: An Entertaining Survey of the High Priests and Cultists of Science, Past and Present—was Martin Gardner's second book. A survey of what it described as pseudosciences and cult beliefs, it became a founding document in the nascent scientific skepticism movement. Michael Shermer said of it: "Modern skepticism has developed into a science-based movement, beginning with Martin Gardner's 1952 classic".
Brights movementThe Brights movement is a social movement whose members since 2003 refer to themselves as Brights and have a worldview of philosophical naturalism. Most Brights believe that public policies should be based on science (a body of knowledge obtained and tested by use of the scientific method). Brights are likely to oppose the practice of basing public policies on supernatural doctrines. Brights may therefore be described as secularists.
Scientific communityThe scientific community is a diverse network of interacting scientists. It includes many "sub-communities" working on particular scientific fields, and within particular institutions; interdisciplinary and cross-institutional activities are also significant. Objectivity is expected to be achieved by the scientific method. Peer review, through discussion and debate within journals and conferences, assists in this objectivity by maintaining the quality of research methodology and interpretation of results.
Ad hoc hypothesisIn science and philosophy, an ad hoc hypothesis is a hypothesis added to a theory in order to save it from being falsified. Often, ad hoc hypothesizing is employed to compensate for anomalies not anticipated by the theory in its unmodified form. Scientists are often skeptical of theories that rely on frequent, unsupported adjustments to sustain them. This is because, if a theorist so chooses, there is no limit to the number of ad hoc hypotheses that they could add. Thus the theory becomes more and more complex, but is never falsified.
Pharyngula (blog)Pharyngula, a blog founded and written by PZ Myers, is hosted on ScienceBlogs (2005–2011, in full, and 2011–present, in part) and on FreeThoughtBlogs (2011–present). In 2006 the science journal Nature listed it as the top-ranked blog written by a scientist based on popularity. The blog addresses a range of topics, including Myers's academic specialty, biology. It has become particularly well known for Myers's writing style (characterized by sarcasm) and for his criticism of intelligent design and creationism.
SkepticismSkepticism, also spelled scepticism in British English, is a questioning attitude or doubt toward knowledge claims that are seen as mere belief or dogma. For example, if a person is skeptical about claims made by their government about an ongoing war then the person doubts that these claims are accurate. In such cases, skeptics normally recommend not disbelief but suspension of belief, i.e. maintaining a neutral attitude that neither affirms nor denies the claim.
Center for InquiryThe Center for Inquiry (CFI) is a US nonprofit organization that works to mitigate belief in pseudoscience and the paranormal, as well as to fight the influence of religion in government. The Center for Inquiry was established in 1991 by atheist philosopher and author Paul Kurtz. It brought together two organizations: the Committee for the Scientific Investigation of Claims of the Paranormal (founded by Kurtz in 1976) and the Council for Secular Humanism (founded by Kurtz in 1980).
