Disjunctive syllogism is a valid argument form in propositional logic. It is used when you have a disjunction (an "or" statement) and a negation of one of the disjuncts (the parts of the disjunction). The structure of a disjunctive syllogism can be summarized as follows: 1. \( P \lor Q \) (either P or Q is true) — this is the disjunction.
Diminution, in the context of satire, refers to a technique where the importance or seriousness of a subject is deliberately downplayed to highlight its absurdity or flaws. This often involves portraying a significant issue or a person in a trivial manner, thereby exposing its ridiculousness. By minimizing the subject, the satirist can effectively criticize or make a commentary on it, inviting the audience to reconsider its true value or impact.
The Gaunt factor is a dimensionless quantity that arises in the field of astrophysics and plasma physics, particularly in the context of radiative transfer and the calculation of opacity in stellar atmospheres and hot plasmas. It quantifies the effect of electron scattering on the intensity of radiation in a medium.
Optical depth is a concept used in astrophysics and other fields to quantify how opaque a medium is to radiation, such as light. It provides a measure of how much a beam of light is attenuated as it passes through a medium, such as gas or dust.
Raman scattering is an inelastic scattering process that occurs when light interacts with molecular vibrations, phonons, or other low-frequency excitations in a material. This phenomenon is named after the Indian physicist C.V. Raman, who, along with his colleague, discovered it in 1928. In simple terms, when a monochromatic light source, typically a laser, shines on a sample, most of the light is elastically scattered, meaning it retains its original energy (or wavelength).

CrysTBox aims to provide a user-friendly interface for both personal and professional use, enabling efficient file management and collaboration.
Science and law are two distinct fields that serve different purposes but occasionally overlap in certain areas. ### Science Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. It encompasses various disciplines, including biology, chemistry, physics, social sciences, and more. The scientific method—which involves observation, experimentation, and forming hypotheses—is central to science, enabling scientists to develop theories and make sense of natural phenomena.
LISE++ is a software tool designed for the simulation and analysis of particle transport and reactions, particularly in the context of nuclear physics and related fields. It is an upgraded version of the original LISE (LInear SExtractor) program, which was developed for the experimental study of rare isotopes produced in nuclear reactions, especially in the context of beam and target interactions.
Scientific evidence refers to the body of data and observations that support or refute scientific hypotheses or theories. It is derived from the scientific method, which involves systematic and objective observation, experimentation, and analysis. Key characteristics of scientific evidence include: 1. **Empirical**: It is based on observable and measurable phenomena rather than speculation or opinion. This means that findings can be verified through experimentation or direct observation.
CompuCell3D is an open-source software framework designed for simulating the growth and behavior of multicellular systems. It is particularly focused on modeling biological processes at the cellular level, such as tissue development, cell migration, and morphogenesis. The framework uses a combination of various computational modeling techniques, including the Cellular Potts Model (CPM) and agent-based modeling, to represent biological entities as individual cells with distinct properties.
The term "Cavendish Professors of Physics" refers to a historic academic title associated with the Cavendish Laboratory at the University of Cambridge. The Cavendish Laboratory is a prominent physics research laboratory founded in 1871, named after the 18th-century scientist Henry Cavendish, who is known for his work in the fields of electricity and chemistry.
Look-ahead and backtracking are concepts often associated with algorithm design and problem-solving techniques, particularly in the context of search algorithms. ### Look-ahead: Look-ahead is a strategy used to anticipate the consequences of decisions before committing to them. It involves evaluating several possible future states of a system or a decision path to see what outcomes can arise from various choices.
A **perfect hash function** is a type of hash function that maps a set of keys to unique indices in a hash table without any collisions. This means that each key in the set corresponds to a unique index, allowing for fast retrieval of the associated value with no risk of overlapping positions. Perfect hashing is particularly important in scenarios where the set of keys is static and known in advance. ### Types of Perfect Hash Functions 1.
Closed-circuit television (CCTV) refers to a television system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. Unlike broadcast television, where the signal is openly transmitted, CCTV systems are designed to transmit video signals from specific cameras to specific monitors or recording devices. Key components of a CCTV system typically include: 1. **Cameras**: These can be analog or digital and vary in type and functionality (e.g.
Access control is a security technique that regulates who or what can view or use resources in a computing environment. It involves establishing policies and mechanisms to determine which users have permissions to access specific data, resources, or systems. Access control is crucial for protecting sensitive information and ensuring that only authorized users can perform certain actions. There are several key components and types of access control systems: 1. **Authentication**: This is the process of verifying the identity of a user or system.
"Fabula" and "syuzhet" are terms used in narrative theory, particularly in the context of literary and film studies, to differentiate between the content of a story and the way that content is presented. 1. **Fabula**: This term refers to the raw material of the story, which includes the actual events that occur in the narrative, the characters involved, and the chronological sequence of those events.
"Poiesis" is a term derived from the Greek word "ποίησις," which means "creation" or "production." It is often used in philosophical, literary, and artistic contexts to refer to the process of bringing something into existence. In ancient Greece, the concept of poiesis encompassed a wide range of creative activities, including poetry, art, and craftsmanship.
The term "sign" can refer to different concepts depending on the context in which it is used. Here are a few common interpretations: 1. **Linguistic Sign**: In linguistics, a sign is the basic unit of meaning and consists of a signifier (the form of the word or phrase) and a signified (the concept it represents). This theory was popularized by Ferdinand de Saussure.

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.
