An Erector Set is a construction toy designed for building various structures and models using metal beams, plates, and other components. The set typically includes a selection of bolts, nuts, and various mechanical parts, allowing builders to create everything from simple shapes to complex mechanical devices. The pieces are often connected using screws and nuts, enabling a wide range of models to be assembled and disassembled. The Erector Set was first introduced in the early 20th century by the A.C.
UPd₂Al₃ is a chemical compound composed of uranium (U), palladium (Pd), and aluminum (Al). It belongs to a class of materials known as intermetallic compounds, which are characterized by the orderly arrangement of two or more different metal atoms in a crystalline structure. In UPd₂Al₃, the composition indicates that there are one uranium atom, two palladium atoms, and three aluminum atoms in the formula.
Constructivism in the philosophy of mathematics is a viewpoint that emphasizes the importance of constructive proofs and methods in mathematical practice. Constructivists assert that mathematical objects do not exist unless they can be explicitly constructed or demonstrated through a finite procedure. This philosophical stance diverges from classical mathematics, which often accepts the existence of mathematical objects based on non-constructive proofs, such as those that rely on the law of excluded middle or other principles that do not provide an explicit construction.
Classical control theory is a framework for analyzing and designing control systems that operate in continuous time. It primarily deals with linear time-invariant (LTI) systems, where the behavior of the system can be described using ordinary differential equations. The main components of classical control theory include: 1. **System Modeling**: Classical control relies on mathematical models to represent dynamic systems. These models can be expressed in terms of transfer functions, which relate the input to the output of a system in the frequency domain.
Entitlement in the context of fair division refers to the concept of determining each participant's fair share or rightful claim to a resource or asset that is to be divided among multiple parties. The goal is to ensure that each party receives their fair portion based on predefined criteria, principles, or contributions.
The Centauro event is a notable incident in the field of astronomy and astrophysics, particularly involving the Centaur class of celestial objects. Centaurs are icy bodies that orbit between the outer planets, generally characterized by unstable orbits that can be affected by the gravity of nearby planets. However, there may be specific events or discoveries associated with Centaur objects that have been labeled as "Centauro events.
The Compton-Getting effect is a phenomenon in astrophysics and cosmic ray physics related to the movement of cosmic rays and their interaction with the Earth's atmosphere or a moving observer. Named after the physicist Arthur Holly Compton, this effect describes how the observed intensity and energy distribution of cosmic rays change due to the motion of the observer relative to the incoming cosmic rays. When an observer (such as Earth) moves through space, it can encounter cosmic rays that have a specific energy spectrum.
OREOcube is a concept or product developed by Nabisco, which is a brand of Mondelēz International, known for producing Oreo cookies. The OREOcube is essentially a three-dimensional cube made up of Oreo cookie elements that can be manipulated and assembled in various ways, often focusing on creativity, construction, and play. While the specifics may vary, the OREOcube is typically aimed at both adults and children, combining the familiar enjoyment of Oreos with an interactive experience.
Security engineering is a field of engineering that focuses on ensuring the security of systems, networks, and data. It encompasses a broad range of practices, processes, and technologies designed to protect assets from threats, vulnerabilities, and attacks. The goal of security engineering is to design and build systems that are resilient to tampering, intrusion, and other security threats. Key aspects of security engineering include: 1. **Risk Assessment:** Identifying potential threats and vulnerabilities in a system and evaluating the risks associated with them.
In the context of cryptography, "snake oil" refers to software, algorithms, or security solutions that are marketed as effective or secure but are actually ineffective, flawed, or even dangerous. The term is derived from the historical marketing of dubious health products, particularly those that were sold with exaggerated claims of their efficacy, akin to the idea of "snake oil" in medicine.
Mark Levinson is an American film director, producer, and writer known for his work in both film and television. Levinson is particularly recognized for his documentary films. One of his notable works is "Freakonomics," released in 2010, which is based on the best-selling book by Steven D. Levitt and Stephen J. Dubner. The film explores various social and economic issues through innovative storytelling and analysis.
I. A. Richards, or Ivor Armstrong Richards (1893–1979), was a significant figure in the fields of literary criticism, rhetoric, and education. He is known for his contributions to the understanding of literary analysis and the importance of reader-response criticism, which focuses on the reader's experience and interpretation of texts rather than solely on the author's intent.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
