Mental Chronometry
Mental chronometry is the study of reaction time (RT; also referred to as "response time") in perceptual-motor tasks to infer the content, duration, and temporal sequencing of mental operations. Mental chronometry is one of the core methodological paradigms of human experimental and cognitive psychology, but is also commonly analyzed in psychophysiology, cognitive neuroscience, and behavioral neuroscience to help elucidate the biological mechanisms underlying perception, attention, and decision-making across species. Mental chronometry uses measurements of elapsed time between sensory stimulus onsets and subsequent behavioral responses. It is considered an index of processing speed and efficiency indicating how fast an individual can execute task-relevant mental operations. Behavioral responses are typically button presses, but eye movements, vocal responses, and other observable behaviors can be used. RT is constrained by the speed of signal transmission in white matter as well as the processing efficiency of neocortical gray matter. Conclusions about information processing drawn from RT are often made with consideration of task experimental design, limitations in measurement technology, and mathematical modeling.

Timor–Alor–Pantar Languages
The Timor–Alor–Pantar (TAP) languages are a family of Papuan (non-Austronesian) languages spoken in Timor, Kisar, and the Alor archipelago in Southern Indonesia. Holton and Klamer (2018) classify Timor–Alor–Pantar as an independent language family, since they find links with Trans-New Guinea too unconvincing.

Philosophical Reflections in the Naisadhacarita
Philosophical Reflections in the Naisadhacarita is the doctoral (Ph.D.) thesis of Harekrishna Meher done in Banaras Hindu University in 1981. It discusses philosophical ideas as reflected in the Sanskrit Mahakavya ‘Naisadhacaritam’ authored by the distinguished poet Sriharsa (12th century). This book (ISBN:9788185094212), first published in 1989 by Punthi Pustak Calcutta, is circulated worldwide. Naisadhacarita Mahakavya of poet Sriharsa enjoys a prominent position among the five great epics of Sanskrit literature. Also known as ‘Naishadha’ or ‘Naishadhiya’, this epic contains twenty-two cantos completed with 2827 verses. Its main theme is the story of love between Nala, the King of Nisadha country and Damayanti, the Princess of Vidarbha. The story of Nala and Damayanti is found in the Mahabharata of Vyasa and Kathasaritsagara of Somadeva. The episode of the epic has been taken from the Mahabharata. Poet Sriharsa has remodelled the story and has added the sentiment of love to it.

LOL
LOL, or lol, is an acronym for laugh(ing) out loud or lots of laughs, and a popular element of Internet slang. It was first used almost exclusively on Usenet, but has since become widespread in other forms of computer-mediated communication and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms for more emphatic expressions of laughter such as LMAO ("laugh(ing) my ass off") and ROFL (or its older form ROTFL; "roll(ing) on the floor laughing"). Other unrelated expansions include the now mostly obsolete "lots of luck" or "lots of love" used in letter-writing. The list of acronyms "grows by the month", and they are collected along with emoticons and smileys into folk dictionaries that are circulated informally amongst users of Usenet, IRC, and other forms of (textual) computer-mediated communication. These initialisms are controversial, and several authors recommend against their use, either in general or in specific contexts such as business communications. The Oxford English Dictionary first listed LOL in March, 2011.

Criticism of the Pledge of Allegiance
The Pledge of Allegiance of the United States has been criticized on several grounds. Its use in government funded schools has been the most controversial, as critics contend that a government-sanctioned endorsement of religion violates the Establishment Clause of the First Amendment to the U.S. Constitution. Arguments against the pledge include that the pledge itself is incompatible with democracy and freedom, pledges of allegiance are features of totalitarian states such as Nazi Germany, and that the pledge was written to honor Christopher Columbus and to sell flags.

Nature
Nature has two inter-related meanings in philosophy and natural philosophy. On the one hand, it means the set of all things which are natural, or subject to the normal working of the laws of nature. On the other hand, it means the essential properties and causes of individual things. How to understand the meaning and significance of nature has been a consistent theme of discussion within the history of Western Civilization, in the philosophical fields of metaphysics and epistemology, as well as in theology and science. The study of natural things and the regular laws which seem to govern them, as opposed to discussion about what it means to be natural, is the area of natural science. The word "nature" derives from Latin nātūra, a philosophical term derived from the verb for birth, which was used as a translation for the earlier (pre-Socratic) Greek term phusis, derived from the verb for natural growth. Already in classical times, philosophical use of these words combined two related meanings which have in common that they refer to the way in which things happen by themselves, "naturally", without "interference" from human deliberation, divine intervention, or anything outside what is considered normal for the natural things being considered. Understandings of nature depend on the subject and age of the work where they appear. For example, Aristotle's explanation of natural properties differs from what is meant by natural properties in modern philosophical and scientific works, which can also differ from other scientific and conventional usage. Stoicism encourages practitioners to live in accordance with nature. Pyrrhonism encourages practitioners to use the guidance of nature in decision making.

Language Game
A language-game (German: Sprachspiel) is a philosophical concept developed by Ludwig Wittgenstein, referring to simple examples of language use and the actions into which the language is woven. Wittgenstein argued that a word or even a sentence has meaning only as a result of the "rule" of the "game" being played. Depending on the context, for example, the utterance "Water!" could be an order, the answer to a question, or some other form of communication.

Pontifical Academy of Sciences
The Pontifical Academy of Sciences (Italian: Pontificia accademia delle scienze, Latin: Pontificia Academia Scientiarum) is a scientific academy of the Vatican City, established in 1936 by Pope Pius XI, and thriving with the blessing of the Papacy ever since. Its aim is to promote the progress of the mathematical, physical, and natural sciences and the study of related epistemological problems. The Academy has its origins in the Accademia Pontificia dei Nuovi Lincei ("Pontifical Academy of the New Lynxes"), founded in 1847 as a more closely supervised successor to the Accademia dei Lincei ("Academy of Lynxes") established in Rome in 1603 by the learned Roman Prince, Federico Cesi (1585–1630), who was a young botanist and naturalist, and which claimed Galileo Galilei as its president. The Accademia dei Lincei survives as a wholly separate institution. The Academy of Sciences, one of the Pontifical academies at the Vatican in Rome, is headquartered in the Casina Pio IV in the heart of the Vatican Gardens. The academy holds a membership roster of the most respected names in 20th century science, including such Nobel laureates as Ernest Rutherford, Max Planck, Otto Hahn, Niels Bohr, Erwin Schrödinger, and Charles Hard Townes.

Na'vi Language
The Naʼvi language (Naʼvi: Lìʼfya leNaʼvi) is the constructed language of the Naʼvi, the sapient humanoid indigenous inhabitants of the fictional moon Pandora in the 2009 film Avatar. It was created by Paul Frommer, a professor at the USC Marshall School of Business with a doctorate in linguistics. Naʼvi was designed to fit James Cameron's conception of what the language should sound like in the film, to be realistically learnable by the fictional human characters of the film, and to be pronounceable by the actors, but to not closely resemble any single human language. When the film was released in 2009, Naʼvi had a growing vocabulary of about a thousand words, but understanding of its grammar was limited to the language's creator. However, this has changed subsequently as Frommer has expanded the lexicon to more than 2900 words and has published the grammar, thus making Naʼvi a relatively complete, learnable and serviceable language.
