PGF/TikZ is a powerful package used in LaTeX for creating graphics programmatically. - **PGF**: Stands for "Portable Graphics Format." It serves as a backend for producing graphics and includes functionality for creating figures and diagrams in a way that is highly customizable. PGF is essentially a lower-level interface. - **TikZ**: Stands for "TikZ ist kein Zeichenprogramm," which translates to "TikZ is not a drawing program.
Trivial Graph Format (TGF) is a simple text-based format used to represent graphs. It is designed to be easy to read and write, making it a suitable choice for basic graph data representation, particularly in contexts where simplicity is more important than complexity or efficiency. In TGF, a graph is represented using two sections: 1. **Node Section**: This section lists the nodes (or vertices) of the graph.
Oceanic dispersal refers to the process by which organisms, such as plants, animals, and microorganisms, spread across oceanic waters and may come to inhabit new areas or islands. This phenomenon can occur through various mechanisms, including: 1. **Currents**: Ocean currents can transport organisms across vast distances. For example, drifting plankton can be carried by currents from one region to another.
The Hadwiger number, denoted as \( H(G) \) for a graph \( G \), is a numerical graph invariant that represents the maximum number \( k \) such that the graph \( G \) can be colored with \( k \) colors without forming any monochromatic complete graph \( K_t \) for every \( t \leq k \).
Heuristic routing refers to a method used in network routing and computer science where heuristic techniques are employed to find efficient paths or solutions to routing problems. Heuristics are problem-solving strategies that use readily accessible, though often limited, information to generate good enough solutions to complex problems within a reasonable timeframe.
In the context of physics, particularly quantum mechanics, a "hidden variable" refers to an unobservable property or parameter that deterministically influences the outcomes of quantum measurements. The term is often associated with theories that attempt to explain the seemingly random behavior of quantum systems by positing that there are underlying factors we cannot measure or observe directly. In quantum mechanics, the outcomes of measurements are fundamentally probabilistic, as described by the wave function and governed by the principles of superposition and entanglement.
The Grzegorczyk hierarchy is a classification of functions based on their computability in the context of mathematical logic and computability theory. It provides a way to categorize certain classes of total recursive functions, which are functions that are defined for all natural numbers. The hierarchy is named after the Polish mathematician and logician Andrzej Grzegorczyk, who introduced it in the context of studying the structure of computable functions.
"Digesting Duck" could refer to a few different concepts, but it's not a widely recognized term in common use. It might be a playful or metaphorical phrase. For example, it could refer to a duck that is in the process of digesting food or a humorous notion about how ducks "digest" their surroundings or experiences.
AI@50 is an initiative aimed at showcasing the potential and importance of artificial intelligence (AI) in various industries and societal applications as it approaches significant milestones in its development and integration into everyday life. It may involve discussions, conferences, or projects that reflect on the progress of AI over the last several decades, anticipating its future impact and fostering collaboration among experts, businesses, and policymakers.
Vasily Aksyonov is a physicist known for his contributions to the field of theoretical and experimental physics. As of my last knowledge update in October 2021, specific details about his research and accomplishments were not widely covered in mainstream scientific literature or news. If he has gained prominence in the field or achieved notable advancements after that date, I would not have that information. Please check the latest sources or scientific publications for the most current information on his work and contributions.
Historians of technology study the development, impact, and societal implications of technology throughout history. This interdisciplinary field examines the relationship between technology and various aspects of society, including culture, politics, economics, and the environment. Historians of technology explore how technological innovations have shaped human experiences and influenced historical events, as well as how social values and cultural contexts have affected the development and use of technology.
"Works" typically refers to various texts, publications, or bodies of research that explore the history of science. The history of science encompasses the development of scientific ideas, practices, institutions, and the social contexts in which they emerged.
The Continuity Thesis is a concept primarily discussed in the context of history, philosophy, and sociology. It suggests that there is a consistent, uninterrupted progression or evolution of ideas, practices, or institutions over time, rather than radical breaks or discontinuities. This thesis posits that certain themes, values, or structures remain persistent even amidst changes and transformations in society.
The history of science and technology is the study of how scientific knowledge and technological advancements have developed over time, and how these developments have influenced society and the natural world. This interdisciplinary field examines the evolution of scientific theories and practices, the emergence of technological inventions, and the reciprocal relationship between science, technology, culture, and social change. ### Key Aspects 1.
The term "Plate Tectonics Revolution" refers to the significant shift in geological thought that occurred in the mid-20th century when the theory of plate tectonics was developed and widely accepted. Prior to this development, the prevailing belief was based on the concept of continental drift, proposed by Alfred Wegener in 1912, which suggested that continents had once been joined together and had drifted apart over geology time.
"Studies in History of Biology" typically refers to a field or interdisciplinary area focused on exploring the historical development of biological concepts, theories, and practices. This field examines how biological knowledge has evolved over time and the social, cultural, and scientific contexts that have influenced this evolution.
The Vakhitov–Kolokolov stability criterion is a condition used in the study of nonlinear wave phenomena, particularly in the stability analysis of solitary waves or pulses in various physical systems, such as nonlinear optics and fluid dynamics. The criterion helps determine whether a given solitary wave solution to a nonlinear partial differential equation is stable or unstable under small perturbations.
Sonnet studies is an area of literary scholarship that focuses on the analysis, interpretation, and appreciation of sonnets as a poetic form. The sonnet, which originated in Italy in the 13th century and became particularly popular in the Renaissance, is characterized by its specific structural features, such as a fixed number of lines, a particular rhyme scheme, and often a thematic organization that includes a volta (or turn in the argument or emotion).
The term "décima" can refer to a couple of different concepts, depending on the context: 1. **Poetic Form**: In literature, a décima is a form of poetry that consists of ten lines (hence the name, from the Spanish word for "tenth"). It typically follows a specific rhyme scheme, often ABBAACCDDC. The décima is a traditional form in Spanish poetry and has its roots in the 16th century.

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.
