The absolute threshold refers to the minimum level of stimulus intensity that is necessary for a person to detect a stimulus 50% of the time. In other words, it is the lowest amount of physical energy that can be detected by the sensory organs. The concept is often used in psychology and sensory perception studies to measure the sensitivity of individual senses, such as hearing, vision, taste, touch, and smell.
Sensory analysis is a scientific method used to evaluate and measure the sensory properties of products, particularly food and beverages, based on human perception. It involves using the senses—such as taste, smell, sight, touch, and hearing—to assess the attributes and quality of a product. This analysis can help in understanding how consumers perceive a product and can guide product development, quality control, and marketing strategies.
Radiation detection refers to the methods and technologies used to identify and measure the presence of ionizing radiation, which can include alpha particles, beta particles, gamma rays, and X-rays. The goal of radiation detection is typically to assess radiation levels in the environment, monitor exposure to individuals, safeguard against radiation hazards, and ensure compliance with safety regulations. Radiation detection devices, known as radiation detectors, come in various types, each suited for specific applications.
Susan Goldstine is a mathematician known for her work in the fields of mathematics and mathematics education. She is particularly recognized for her contributions to the use of technology in teaching mathematics, especially through computer software and other digital tools.
The Statue of Liberty in Leicester is a lesser-known replica of the iconic Statue of Liberty in New York City. It is located in the city of Leicester, England, and stands outside the city’s New Walk Museum and Art Gallery. This replica was created as a tribute to the American contribution to the First World War, particularly to honor the American soldiers who fought alongside British forces.
Dade's Conjecture is a statement in the field of representation theory, particularly concerning the representations of finite groups and their characters. Formulated by the mathematician Eugene Dade in the 1980s, the conjecture relates to the modifications of characters of a finite group when restricted to certain subgroups.
The term "aporia" has several meanings depending on the context in which it is used: 1. **Philosophical Context**: In philosophy, particularly in the works of Plato, "aporia" refers to a state of puzzlement or doubt. It often arises in discussions that reveal contradictions or challenges to one's understanding of a concept. Plato uses aporia to encourage deeper inquiry and philosophical questioning.
Ars dictaminis, often translated as "the art of letter writing," was a significant aspect of medieval education that focused on the composition of formal letters and documents. Developed during the Middle Ages, particularly in the 12th century, it became an essential skill for clerics, officials, and those involved in administrative tasks. The Ars dictaminis encompassed the principles and conventions for writing various types of letters, including those of request, complaint, advice, and even personal correspondence.
Forensic rhetoric, often referred to as judicial rhetoric, is a branch of rhetoric that focuses on arguments presented in legal contexts, particularly in courts of law. It involves the use of persuasive techniques to advocate for a particular interpretation of facts or legal standards in relation to a past event, often centered around issues of guilt or innocence.
Parechesis is a rhetorical term used to describe a figure of speech in which a word is used in a way that it is not intended to refer to its literal meaning, often for the sake of introducing ambiguity or engaging an audience. It typically involves a form of pun or wordplay, where a word has more than one meaning or can be interpreted in multiple ways.
In ring theory, which is a branch of abstract algebra, an **ideal** is a specific subset of a ring that has particular properties allowing it to be used in the construction of quotient rings and in the study of ring homomorphisms. ### Definition: Let \( R \) be a ring (with unity, but this requirement can be relaxed in some contexts).
Public rhetoric refers to the use of language and communication strategies to influence public opinion, engage audiences, and shape social discourse in a public context. It encompasses various forms of expression, including speeches, debates, advertisements, social media, and other platforms where ideas are presented to the public. Key elements of public rhetoric include: 1. **Audience Awareness**: Understanding the beliefs, values, and emotions of the audience to tailor messages effectively.
"Stealing thunder" is a term that can refer to two primary concepts: 1. **In the Context of Rhetoric and Communication**: Stealing thunder refers to a strategy in which a speaker or writer preempts a negative disclosure or criticism by revealing it themselves before anyone else has the chance to do so. This tactic can help them maintain control over the narrative and mitigate potential damage to their reputation or argument. By addressing the issue proactively, they often lessen its impact.
The term "Babou" is often used to refer to the ocelot, a medium-sized wild cat (scientifically known as *Leopardus pardalis*) found primarily in South and Central America, as well as parts of the southern United States. Ocelots are known for their distinctive coat patterns, consisting of spots and stripes that resemble a domestic cat's, but they are larger and more robust.
A 1:18 scale refers to a scale model or representation where 1 unit of measurement on the model equals 18 units of the same measurement in the real object. For example, if a model car is 1:18 scale, it means that 1 inch (or centimeter) on the model represents 18 inches (or centimeters) of the actual car.
Aegis Sonix is a technology often associated with acoustic monitoring and surveillance, used primarily for security applications. While specific details and product offerings can vary, this technology typically involves advanced sound detection and analysis to enhance safety and security measures in various environments. For the most accurate and up-to-date information, please refer to the manufacturer's official documentation or website, as products and technologies may evolve over time.
1:24 scale is a model scale where one unit of measurement on the model represents 24 of the same units in reality. This means that for every 1 part of the model, there are 24 equivalent parts in real life.
In scheme theory, a branch of algebraic geometry, the concept of a "function field" is a fundamental idea associated with the geometrical notion of a variety. Let's break it down: ### Definition 1. **Function Field**: The function field of a variety (or scheme) can be informally thought of as the "field of rational functions" on that variety.
Acoplanarity refers to a geometric condition where two or more objects, often in the context of physics or engineering, do not lie in the same plane. This concept is particularly relevant in fields like particle physics, where it may be used to analyze the interaction of particles and their decay products. In practical terms, when dealing with momentum vectors of particles in high-energy physics, acoplanarity tends to describe a situation where the vectors of the outgoing particles do not all fall within the same planar surface.

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.
