Idiot Light
An idiot light, sometimes "tell-tale" or "warning light", is an indicator of malfunction of a system, indicated by a binary (on/off) illuminated light, symbol or text legend. The "idiot light" terminology arises from popular frustration with automakers' use of lights for crucial functions which could previously be monitored by gauges, so a troublesome condition could be detected and corrected early. Such early detection of problems with, for example, engine temperature or oil pressure or charging system operation is not possible via an idiot light, which lights only when a fault has already occurred – thus providing no advance warnings or details of the malfunction's extent. The Hudson automobile company was the first to use lights instead of gauges for oil pressure and the voltmeter, starting in the mid-1930s.

Weierstrass's Elliptic Functions
In mathematics, Weierstrass's elliptic functions are elliptic functions that take a particularly simple form. They are named for Karl Weierstrass. This class of functions are also referred to as p-functions and they are usually denoted by the symbol ℘. They play an important role in theory of elliptic functions. A ℘-function together with its derivative can be used to parameterize elliptic curves and they generate the field of elliptic functions with respect to a given period lattice.

Elaboration Likelihood Model
The elaboration likelihood model (ELM) of persuasion is a dual process theory describing the change of attitudes. The ELM was developed by Richard E. Petty and John Cacioppo in 1980. The model aims to explain different ways of processing stimuli, why they are used, and their outcomes on attitude change. The ELM proposes two major routes to persuasion: the central route and the peripheral route.

Pace v. Alabama
Pace v. Alabama, 106 U.S. 583 (1883), was a case in which the United States Supreme Court affirmed that Alabama's anti-miscegenation statute was constitutional. This ruling was rejected by the Supreme Court in 1964 in McLaughlin v. Florida and in 1967 in Loving v. Virginia. Pace v. Alabama is possibly the first recorded interracial sex court case in America.

Retrospective Memory
Retrospective memory is the memory of people, words, and events encountered or experienced in the past. It includes all other types of memory including episodic, semantic and procedural. It can be either implicit or explicit. In contrast, prospective memory involves remembering something or remembering to do something after a delay, such as buying groceries on the way home from work. However, it is very closely linked to retrospective memory, since certain aspects of retrospective memory are required for prospective memory.

Power Posing
Power posing is a controversial self-improvement technique or "life hack" in which people stand in a posture that they mentally associate with being powerful, in the hope of feeling and behaving more assertively. Though the underlying science is strongly disputed, its promoters continue to argue that people can foster positive life changes simply by assuming a "powerful" or "expansive" posture for a few minutes before an interaction in which confidence is needed. One popular image of the technique in practice is that of candidates "lock[ing] themselves in bathroom stalls before job interviews to make victory V's with their arms." Power posing was first suggested in a 2010 paper by Dana R. Carney, Amy Cuddy, and Andy Yap in the journal Psychological Science, and came to prominence through a popular TED talk by Cuddy in 2012. However, in 2015 several researchers began reporting that the effect could not be replicated, and, in 2016, Carney issued a statement abandoning the theory. Cuddy, however, continued her research, claiming to have evidence that posture feedback can at least make people feel more powerful. Today, power posing is often cited as an example of the replication crisis in the sciences.

Almaguin Highlands
The Almaguin Highlands Region (colloquially known as Almaguin, also referred to as 'the Highlands') in Ontario, Canada, covers approximately 5,200 km2 (2,000 sq mi) comprising the eastern half of Parry Sound District. It is bounded by Muskoka in the south, and by Lake Nipissing and Nipissing District in the north. The eastern edge abuts the western boundary of Algonquin Provincial Park, whereas the western boundary of the Almaguin Highlands is generally regarded to be the mid east-west point of Parry Sound District. Originally derived from the words, Algonquin, Magnetawan, and Seguin. Almaguin is now used to describe the marketing region of East Parry Sound.

Gamma-Aminobutyric Acid
Gamma-Aminobutyric acid, or γ-aminobutyric acid /ˈɡæmə əˈmiːnoʊbjuːˈtɪrɪk ˈæsɪd/, or GABA /ˈɡæbə/, is the chief inhibitory neurotransmitter in the developmentally mature mammalian central nervous system. Its principal role is reducing neuronal excitability throughout the nervous system. GABA is sold as a dietary supplement in many countries. It has been traditionally thought that exogenous GABA (i.e. taken as a supplement) doesn't cross the blood-brain barrier, however data obtained from more current research indicates that it may be possible.
