Edmund Cartwright (1743–1823) was an English clergyman and inventor, best known for his invention of the power loom, which revolutionized the textile industry during the Industrial Revolution. Cartwright's loom, patented in 1785, mechanized the process of weaving cloth, significantly increasing production efficiency and reducing the amount of manual labor required.
The "Hacker Manifesto" is a text written by the hacker and activist known as "Phiber Optik" (real name: Loyd Blankenship) in 1986. It is a reflective piece that articulates the thoughts and philosophies of hackers at that time, emphasizing the hacker ethic and the culture surrounding hacking.
Enterprise Resource Planning (ERP) refers to a type of software system that organizations use to manage and integrate the essential parts of their business operations. An ERP software system can integrate planning, purchasing inventory, sales, marketing, finance, human resources, and more into a single system. ### Key Features of ERP: 1. **Integration**: ERP systems integrate various business processes and functions into one complete system to streamline processes and information across the organization.
Sales and Operations Planning (S&OP) is a strategic process that aligns a company’s supply chain, production, and sales plans to ensure that supply meets demand in the most efficient and effective manner. It typically involves integrating various departments such as sales, marketing, finance, and operations to create a unified plan that supports the company’s overall business strategy.
As of my last knowledge update in October 2023, there is no widely recognized technology or tool specifically named "WordMARC." However, "MARC" typically refers to the Machine-Readable Cataloging format, which is a standard for the representation and exchange of bibliographic and related information in library settings.
Qualitative psychological research is a methodological approach within psychology that focuses on understanding human behavior, thoughts, feelings, and experiences through the collection and analysis of non-numerical data. Unlike quantitative research, which relies on statistics and numerical measurements to test hypotheses, qualitative research emphasizes the exploration of phenomena in depth and within context.
Charles Spearman (1863–1945) was a British psychologist known for his work in statistics and psychology, particularly in the field of intelligence testing. He is best known for developing the concept of the "g factor," or general intelligence, which posits that a common factor underlies various cognitive abilities. Spearman introduced a statistical method called factor analysis, which allows researchers to identify underlying relationships between different variables, including cognitive tasks.
Gustav Fechner (1801–1887) was a German philosopher, physicist, and psychologist who is best known for founding psychophysics, a field that explores the relationships between physical stimuli and the sensations and perceptions they produce. Fechner’s work laid the groundwork for modern experimental psychology. One of his most significant contributions was the formulation of Fechner's Law, which quantifies the relationship between the intensity of a stimulus and the resulting sensation.
Horatio Pollock is not a widely recognized name in mainstream culture or academia, and there may be no figures of notable prominence by that exact name as of my last knowledge update in October 2023. It’s possible that the name could refer to a lesser-known individual or be used in a specific context such as literature, a fictional character, or an obscure historical figure.
Joan Garfield is a prominent educator and statistician known for her work in statistics education. She has made significant contributions to advancing the understanding and teaching of statistics, particularly in the context of technology and data analysis. Garfield has been involved in various initiatives aimed at improving statistical literacy and has published numerous articles and resources related to statistics education.
Klaus Kubinger is an Austrian psychologist and statistician known for his work in the fields of psychological measurement and test theory. He has contributed to various aspects of psychological assessment, including the development and validation of tests and measures used in psychological research and practice.
A Controlled NOT gate, commonly referred to as a CNOT gate or CX gate, is an essential component in quantum computing. It is a two-qubit gate that performs a NOT operation (also known as a bit-flip) on a target qubit only when a control qubit is in the state \(|1\rangle\).
The Margolus–Levitin theorem is a result in quantum information theory that establishes a limit on the maximum speed at which information can be processed by a quantum system. Specifically, it provides a bound on the rate at which a quantum system can perform operations or computations. According to the theorem, a quantum system with a given energy E can perform at most 2E/ħ (where ħ is the reduced Planck's constant) operations per unit time.
The No-Broadcasting Theorem is a result from quantum information theory that pertains to the limitations of quantum state transmission and the process of broadcasting entangled states. It illustrates the fundamental differences between classical and quantum information sharing. The theorem states that it is impossible to perfectly broadcast an unknown quantum state.
ISO 10303, commonly known as STEP (Standard for the Exchange of Product model data), is an international standard for the representation and exchange of product model data. It is widely used in various industries, especially in manufacturing, engineering, and product design, facilitating a wide range of applications such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management (PLM).
The Quantum Communications Hub is typically a research initiative or collaborative project focused on advancing the field of quantum communication technology. These hubs aim to explore and develop new methods of secure communication using the principles of quantum mechanics, such as quantum key distribution (QKD) and entanglement. Key objectives of Quantum Communications Hubs often include: 1. **Research and Development**: Conducting cutting-edge research in quantum technologies to understand and develop quantum communication protocols and systems.
A Quantum Markov chain is an extension of classical Markov chains to the realm of quantum mechanics. Just as classical Markov chains model systems that evolve probabilistically over time, quantum Markov chains aim to capture the dynamics of quantum states as they evolve, potentially influenced by measurements and interactions with environments or other quantum systems.
A **quantum cellular automaton (QCA)** extends the classical concept of cellular automata into the realm of quantum mechanics. In a traditional cellular automaton, a grid of cells can be in one of several states and evolves over discrete time steps according to a set of rules based on the states of neighboring cells. These rules are deterministic and depend on classical physics.
Quantum entanglement is a fundamental phenomenon in quantum mechanics where pairs or groups of particles become linked in such a way that the quantum state of one particle cannot be described independently of the state of the other(s), even when the particles are separated by a large distance. This correlation persists regardless of the distance separating the particles, leading to the term "spooky action at a distance," famously described by Albert Einstein.
Rigetti Computing is a company focused on developing quantum computing technology. Founded in 2013 by Chad Rigetti, the company aims to build and provide quantum processors and software for a wide range of applications, harnessing the capabilities of quantum mechanics to perform computations that are infeasible for classical computers.

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.
