"Numbers" is an American television series that aired from 2005 to 2010. It was created by Nick Falco and is centered around an FBI agent, Don Eppes, who uses mathematical concepts and equations to help solve crimes, with the assistance of his brother, Charlie Eppes, a brilliant mathematician. The show features a combination of procedural crime-solving and the application of mathematics to real-world problems. Throughout its six seasons, "Numbers" aired a total of 118 episodes.
Classical elements refer to a set of fundamental substances that various ancient cultures believed to compose the physical universe and shape the qualities of matter. The concept of classical elements has appeared in various forms across different civilizations, but some of the most well-known are: 1. **Ancient Greece**: The Greek philosopher Empedocles proposed that four elements make up all matter: - **Earth**: Represents solidity and stability. - **Water**: Symbolizes fluidity and adaptability.
The hole argument is a philosophical and conceptual issue in the foundation of general relativity, primarily associated with the work of Albert Einstein and later discussions by philosophers and physicists. It arises in the context of the interpretation of spacetime and the nature of physical objects within it. ### What is the Hole Argument? 1. **Concept of the Hole**: Imagine a region of spacetime where the gravitational field is described by a specific metric (the mathematical representation of spacetime geometry).
The term "sublunary sphere" originates from ancient and medieval cosmology, particularly in the context of Aristotelian philosophy. In this framework, the universe was typically divided into two main realms: the supralunary (above the moon) and the sublunary (below the moon). 1. **Sublunary Sphere**: This realm is considered to encompass everything on Earth and the atmosphere surrounding it, including all terrestrial phenomena.
A fixed-point ocean observatory is a type of research facility or system that is deployed in marine environments to monitor and collect continuous data on various oceanographic parameters. These observatories are typically anchored at specific locations in the ocean and can provide long-term observations that are crucial for understanding ocean processes, climate change, marine ecosystems, and other important scientific questions.
Throughout Earth's geological history, several ancient oceans have existed, often linked to the formation and breakup of supercontinents. Here are some notable ancient oceans: 1. **Panthalassa**: This was the vast global ocean that surrounded the supercontinent Pangaea, which existed during the late Paleozoic and early Mesozoic eras. It is considered the largest ocean in Earth's history.
Marine spatial planning (MSP) is an integrated process that guides the sustainable use and management of marine resources and spaces. It aims to balance ecological, economic, and social objectives by organizing human activities in marine environments. MSP involves the assessment and mapping of ocean spaces to identify suitable areas for various uses, such as fishing, shipping, tourism, conservation, and renewable energy development, while minimizing conflicts and environmental impacts.
Tropical instability waves (TIWs) are large-scale atmospheric phenomena that occur in the tropical regions of the ocean, primarily in the equatorial Pacific. They are characterized by oscillations in sea surface temperature, ocean currents, and atmospheric conditions. These waves typically have a wavelength of several hundred kilometers and periods of roughly 10 to 40 days.
Program Evaluation and Review Technique (PERT) is a project management tool used to analyze and represent the tasks involved in completing a given project. It was developed in the 1950s for the Polaris submarine project and is especially useful for projects with uncertain activity durations. ### Key Features of PERT: 1. **Graphical Representation**: PERT uses a flowchart-like diagram to represent project tasks and their interrelationships. Each task is depicted as a node or a milestone.
M. Parker Givens is a figure notable for his work in finance and entrepreneurship, particularly as a private investor and advisor. His focus is often on business strategy, investment opportunities, and helping startups or emerging companies navigate financial challenges. If there are specific aspects or contributions of M.
As of my last knowledge update in October 2023, there is no widely recognized entity, product, or concept known as "Outime." It is possible that it is a new term, product, or company that has emerged since then.
A doublet lens is an optical component consisting of two individual lenses made from different types of glass or materials, which are cemented together. The primary purpose of a doublet lens is to correct optical aberrations that can occur with single-element lenses. By combining lenses with different refractive indices and dispersion properties, a doublet can reduce chromatic aberration (color fringing) and improve image quality.
As of my last update in October 2023, "PSF Lab" could refer to different things depending on the context. One well-known initiative is the **Python Software Foundation (PSF)** and its associated labs or projects, which often focus on enhancing and supporting the Python programming language and its ecosystem.
A phase telescope, although not a commonly used term, generally refers to a type of optical instrument that utilizes the principles of phase contrast microscopy or interferometry to enhance the visibility of transparent or phase-object materials in imaging. The concept is primarily applied in microscopy and imaging systems rather than traditional astronomical telescopes.
Photon diffusion refers to the process by which photons (particles of light) spread out as they scatter in a medium. This concept is particularly relevant in the context of light interacting with materials, especially those that are semi-transparent or opaque, like biological tissues, certain gases, and particulates in the atmosphere. In a medium where photons can scatter, the initial directional input of the light becomes randomized due to collisions with particles within the material.
A mechanical splice is a method used to join two optical fibers together, enabling the transmission of light signals from one fiber to the other. This type of splice does not require fusion (melting the fibers together) but instead uses a mechanical device to align and hold the fibers in place.
Paper craft refers to a range of artistic activities that involve creating objects or decorations using paper. This can include a variety of techniques and styles, such as: 1. **Origami**: The traditional Japanese art of folding paper into intricate shapes and figures, such as animals, flowers, or geometric forms. 2. **Papercutting**: A technique where designs are cut out of paper to create intricate images and patterns. This can be done by hand with scissors or using a craft knife.
Kaldor–Hicks efficiency is a concept in welfare economics used to evaluate economic allocations and policy changes. It represents a criterion for judging the desirability of an allocation of resources or a policy decision based on the potential for wealth creation and redistribution.
Method ringing is a technique used in change ringing, specifically in the ringing of bells. It involves ringing a series of changes (or sequences) in which the order of the bells changes according to a specified method or pattern. Each method has its own distinct pattern of changes, and these are often defined mathematically. In method ringing, a specific set of rules dictates how the bells are to be rung, resulting in a predetermined sequence that can vary in complexity.
"Braids" can refer to a few different concepts depending on the context: 1. **Hairstyle**: In fashion and grooming, braids are a method of weaving strands of hair together to create intricate hairstyles. Common types of braids include a traditional three-strand braid, fishtail braid, crown braid, and Dutch braid, among others. Braids can be used for various looks, from casual to formal.

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.
