Prisons are facilities designed to confine individuals who have been convicted of crimes and sentenced to incarceration. They serve several primary purposes, including: 1. **Punishment**: Prisons impose a penalty on individuals found guilty of violating laws, reflecting society's condemnation of their actions. 2. **Deterrence**: By removing offenders from the community and subjecting them to the consequences of their actions, prisons aim to deter both the individual and others from committing similar crimes.
Crime Prevention Through Environmental Design (CPTED) is a multi-disciplinary approach to deterring criminal behavior through environmental design. The concept is based on the idea that the physical environment can influence people's behavior and can be structured in a way to reduce opportunities for crime. ### Key Principles of CPTED: 1. **Natural Surveillance**: Designing the environment to increase visibility, making it easier for people to observe activities and identify suspicious behavior.
Cyberwarfare refers to the use of digital attacks by one nation-state to disrupt the critical computer systems of another nation-state, typically for the purpose of causing harm, espionage, or gaining a strategic advantage. This form of warfare can involve hacking, virus deployment, denial-of-service attacks, and the manipulation of data and systems to achieve political, economic, or military objectives.
A polariton is a quasiparticle that arises from the strong coupling of light (photons) with a material excitations, such as excitons, phonons, or other collective excitations in a medium. Polariton behavior occurs when the interactions between photons and these excitations are significant enough to lead to the formation of a new type of particle that exhibits mixed characteristics of both light and the excitations of the material.
The number 4 is an integer that follows 3 and precedes 5. It is an even number and can be represented in various contexts, such as a quantity, a score, or a position in a sequence.

The number 168 is an integer that follows 167 and precedes 169. In terms of its properties: - It is an even number. - It is a composite number, meaning it has factors other than 1 and itself.
Gas is one of the four fundamental states of matter, along with solid, liquid, and plasma. In a gaseous state, substances have particles that are widely spaced and move freely, which gives gases the ability to expand to fill the volume of their container. Some key characteristics of gases include: 1. **Indefinite Shape and Volume**: Gases do not have a fixed shape or volume. They take the shape and volume of their container.
Neptunium is a chemical element with the symbol Np and atomic number 93. It is a silvery, radioactive metal that belongs to the actinide series of the periodic table. Neptunium is notable for being the first transuranium element, meaning it was the first element discovered that has an atomic number greater than that of uranium (92). Neptunium was discovered in 1940 by Edwin McMillan and Philip H.
FTPS, or FTP Secure, is an extension of the File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and the older Secure Sockets Layer (SSL) cryptographic protocols. FTPS is used to securely transfer files over a network, ensuring that the data remains confidential and protected from eavesdropping or tampering during transmission.
The number 227 is a three-digit integer that follows 226 and precedes 228. Here are a few interesting facts about the number 227: 1. **Prime Number**: It is a prime number, meaning it is only divisible by 1 and itself.
The number 229 is a natural number that follows 228 and precedes 230. It is an odd integer and can be analyzed mathematically in various ways: 1. **Prime Number**: 229 is a prime number, meaning it has no positive divisors other than 1 and itself.

Waiuku is a small town located in the Auckland Region of New Zealand, situated at the southern end of the Auckland metropolitan area. It lies near the mouth of the Waiuku River, where it meets the Tasman Sea, and is surrounded by the rugged landscape of the Franklin District. Historically, Waiuku served as a significant settlement for early European settlers and has a rich history that includes connections to the logging and farming industries.
The term "black box" can refer to several concepts depending on the context in which it is used. Here are some common interpretations: 1. **Engineering and Science**: In engineering, a black box refers to a system or device whose internal workings are not known or not relevant for the purposes of observation or analysis. Only the inputs and outputs are observed, and the processes that occur inside the box are not examined.
The W69 is a type of thermonuclear warhead that was developed by the United States during the Cold War. It was designed for use on various delivery systems, including the Air Force's AGM-69 Short-Range Attack Missile (SRAM) and other military platforms. The W69 is notable for its compact size and was part of the U.S. nuclear stockpile during the latter half of the 20th century.
The term "facet" can have different meanings depending on the context in which it is used. Here are a few common interpretations: 1. **General Definition**: A facet refers to one side, aspect, or feature of something. It can describe any one of the many parts that make up a whole. 2. **Geology and Gemology**: In the context of gemstones, a facet is one of the flat polished surfaces on a cut gem.
Boxicity is a mathematical concept related to graph theory. It refers to a particular way of representing a graph using boxes (or rectangles) in a Euclidean space. More specifically, the boxicity of a graph is defined as the minimum number of dimensions (d) such that the graph can be represented as the intersection of a family of axis-aligned boxes in \( \mathbb{R}^d \).
As of my last knowledge update in October 2023, "Teahitia" does not refer to any widely recognized concept, place, or term in popular culture, geography, or any notable field of study. It's possible that it could refer to a specific brand, product, or niche subject not broadly covered in general information sources.
Cobalt-60 is a radioactive isotope of cobalt, denoted as \(^{60}\text{Co}\). It has important applications in various fields, particularly in medicine and industry. Here are some key points about Cobalt-60: 1. **Radioactive Properties**: Cobalt-60 undergoes beta decay to become nickel-60, emitting gamma radiation in the process. Its half-life is approximately 5.
A phasor is a complex number representation of a sinusoidal function that is often used in electrical engineering and signal processing, particularly when analyzing alternating current (AC) circuits. The concept simplifies the mathematical treatment of sinusoidal signals by converting time-domain waveforms into the frequency domain.

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.
