Comparative illusion is a psychological concept that refers to the tendency of individuals to perceive themselves, their abilities, or their situations as better than those of others, often based on subjective comparisons. This can occur in various domains, such as intelligence, physical attractiveness, or social skills, where people may overestimate their standing relative to their peers.
The Tensed-S condition is a concept in theoretical linguistics, particularly in the field of syntax and semantics, associated with the study of tense, mood, and aspect in language. It was proposed by linguists such as David Pesetsky, and it deals with the interaction between the syntax of sentences and their tense semantics. The Tensed-S condition asserts that a sentence must have a tense that is compatible with its syntactic structure.
Nominalization refers to the process of transforming verbs (or sometimes adjectives) into nouns. This linguistic process plays a significant role in various fields, including grammar, writing, and even disciplines like philosophy and linguistics. Here are some remarks on nominalization: 1. **Definition and Function**: - Nominalization typically involves creating a noun form from a verb (e.g., "decide" becomes "decision") or from an adjective (e.g.
Tennessine is a synthetic element with the symbol Ts and atomic number 117. It is one of the superheavy elements in the periodic table and belongs to the group of halogens, which are typically found in Group 17.

Abelian and Tauberian theorems are concepts from mathematical analysis and number theory, specifically related to the convergence of series and the properties of generating functions. Here’s a brief overview of each: ### Abelian Theorem The Abelian theorem typically refers to the Abel's test, which is a criterion for the convergence of series and power series.
Position tolerance is a type of geometric tolerance used in engineering and manufacturing to define the permissible variation in the location of a feature or part relative to a specified datum. It is primarily used in the context of technical drawings and Computer-Aided Design (CAD) to ensure that the parts can be manufactured and assembled with the desired level of accuracy. Position tolerance specifies a zone within which the corresponding feature must fall.
The Robinson list, also known as the Robinson Anti-Spam List, is a registry for individuals in the United Kingdom who do not wish to receive unsolicited marketing communications, including telemarketing calls, direct mail, and emails. It was established to protect consumers from unwanted marketing practices. Individuals can register their details on the Robinson list to indicate their preference to opt-out of receiving these types of communications.
**Barr v. American Association of Political Consultants, Inc.** is a notable legal case decided by the U.S. Supreme Court in 2020. The case addressed the constitutionality of the Telephone Consumer Protection Act (TCPA), specifically a provision that barred robocalls to cell phones. The controversy arose over a 2015 amendment that exempted government-debt collection calls from this ban while maintaining the prohibition on other types of robocalls.
The Do Not Disturb (DND) Registry is a system that allows individuals to opt-out of receiving unsolicited telemarketing calls. Different countries have their own versions of this registry, but the primary goal is to protect consumers from unwanted solicitations by telemarketers. When a person registers their phone number in the Do Not Disturb Registry, telemarketers are prohibited from contacting that number with promotional calls. The specific rules and regulations governing the DND Registry can vary by country.
"Plant test number" could refer to different concepts depending on the context in which it's used. Here are a few possibilities: 1. **Industrial or Manufacturing Context**: In some manufacturing facilities, a "plant test number" could be an identifier associated with a specific test conducted on machinery, equipment, or processes within a plant. This could involve quality control tests, emissions tests, or production efficiency evaluations.
A ringback number is a designated phone number that is used to play ringing sounds back to a caller while they wait for the recipient to answer. Instead of the traditional ringtone that the caller hears, this service allows the caller to hear music or another message until the recipient picks up the call. Ringback tones are often used for personalization and can include a variety of sounds, such as popular songs, jingles, or custom messages.
"Alpha Centauri or Die!" is a phrase that combines a reference to Alpha Centauri, the closest star system to Earth, with a dramatic imperative. This phrase may be evocative of themes found in science fiction, space exploration, or existential challenges facing humanity, emphasizing the urgency of exploring other star systems or the potential dire consequences of failing to do so.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
