🔗 Computing

In computer science, the ostrich algorithm is a strategy of ignoring potential problems on the basis that they may be exceedingly rare. It is named for the ostrich effect which is defined as "to stick one's head in the sand and pretend there is no problem". It is used when it is more cost-effective to allow the problem to occur than to attempt its prevention.

🔗 Lists 🔗 Anthroponymy

This list of eponymous laws provides links to articles on laws, principles, adages, and other succinct observations or predictions named after a person. In some cases the person named has coined the law – such as Parkinson's law. In others, the work or publications of the individual have led to the law being so named – as is the case with Moore's law. There are also laws ascribed to individuals by others, such as Murphy's law; or given eponymous names despite the absence of the named person.

🔗 Science

In communication theory, the Allen curve is a graphical representation that reveals the exponential drop in frequency of communication between engineers as the distance between them increases. It was discovered by Massachusetts Institute of Technology Professor Thomas J. Allen in the late 1970s.

A related and highly significant finding of Allen's was his identification of the key role of information gatekeepers. Often such interlocutors were poorly recognized by management and yet conveyed vital concepts from just the right people to just the right other people in the organization.

In the United States, the 13th Amendment to the Constitution states the following:

Section 1. Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.

This prohibits slavery and involuntary servitude, but leaves an exception for punishment for a crime of which one has been convicted. Various commentators have accused states of abusing this provision to re-establish systems similar to slavery, or of otherwise exploiting such labor in a manner unfair to local labor.

Starting in the late 2010s and extending into the mid-2020s, a movement emerged to repeal the exception clause from both the federal and state constitutions. As of February 2026, eight states had joined Rhode Island in repealing the exception clause from their state constitutions, while 26 states' constitutions make no mention of either slavery or involuntary servitude and 15 states retain an exception clause.

This is a list of topics that have, at one point or another in their history, been characterized as pseudoscience by academics or researchers. Detailed discussion of these topics may be found on their main pages. These characterizations were made in the context of educating the public about questionable or potentially fraudulent or dangerous claims and practices—efforts to define the nature of science, or humorous parodies of poor scientific reasoning.

Criticism of pseudoscience, generally by the scientific community or skeptical organizations, involves critiques of the logical, methodological, or rhetorical bases of the topic in question. Though some of the listed topics continue to be investigated scientifically, others were only subject to scientific research in the past, and today are considered refuted but resurrected in a pseudoscientific fashion. Other ideas presented here are entirely non-scientific, but have in one way or another impinged on scientific domains or practices.

Many adherents or practitioners of the topics listed here dispute their characterization as pseudoscience. Each section here summarizes the alleged pseudoscientific aspects of that topic.

The Hoover free flights promotion was a marketing promotion run by the British division of the Hoover Company in late 1992. The promotion, aiming to boost sales during the global recession of the early 1990s, offered two complimentary round-trip plane tickets to the United States, worth about £600, to any customer purchasing at least £100 in Hoover products. Hoover had been experiencing dwindling sales as a result of the economic downturn and a sharp increase in competing brands. Hoover was counting on most customers spending more than £100, as well as being deterred from completing the difficult application process, and not meeting its exact terms.

Consumer response was much higher than the company anticipated, with many customers buying the minimum £100 of Hoover products to qualify. It was perceived as two US flights for just £100 with a free vacuum cleaner included. The resulting demand was disastrous for the 84-year-old company. Hoover cancelled the ticket promotion after consumers had already bought the products and filled in forms applying for millions of pounds' worth of tickets. Reneging on the offer resulted in protests and legal action from customers who failed to receive the tickets they had been promised. The campaign was a financial disaster for the company and led to the loss of Hoover's Royal Warrant after the airing of a 2004 BBC documentary. The European branch of the company was eventually sold to one of its competitors, Candy, having never recovered from the losses, the promotion and the subsequent scandal.

The Battle of Palmdale was the attempted shoot-down of a runaway drone by United States Air Force interceptors in the skies over Southern California in mid-August 1956. The drone was launched from Point Mugu Naval Air Station and soon went out of control. Interceptor aircraft took off from Oxnard Air Force Base and caught up with the drone, but were ultimately unable to bring it down, in spite of expending all of their rockets. After it ran out of fuel, the unmanned aircraft crashed in a sparsely populated tract of desert.

During the incident over 1000 acres were scorched and a substantial amount of property was damaged or destroyed.

🔗 Freedom of speech

The Chicago principles are a set of guiding principles intended to demonstrate a commitment to freedom of speech and freedom of expression on college campuses in the United States. Initially adopted by the University of Chicago following a report issued by a designated Committee on Freedom of Expression in 2014 (″Report of the Committee on Freedom of Expression″), they came to be known as the “Chicago principles”, as the Foundation for Individual Rights in Education (FIRE) led a campaign to encourage other universities across the country sign up to the principles or model their own based on similar goals.

Since 2014, a number of other universities have committed to the principles, including Princeton, Purdue, and Washington University in St. Louis. As of August 2020, FIRE reported that 76 U.S. colleges and universities had "adopted or endorsed the Chicago Statement or a substantially similar statement."
