Foam is a substance that consists of many small bubbles of gas trapped in a liquid or solid. It is characterized by its airy structure, which gives it a lightweight and often flexible nature. There are various types of foam, and it can be found in several forms and applications, including: 1. **Types of Foam**: - **Polyurethane Foam**: Commonly used in furniture, mattresses, and insulation.
The CAESAR Competition (Competition for Authenticated Encryption: Security, Applicability, and Robustness) is an initiative aimed at evaluating and assessing the security and practicality of authenticated encryption schemes. It was launched to advance research in cryptography by encouraging the design and analysis of encryption algorithms that provide both confidentiality and integrity, ensuring that data is secure against a variety of attack vectors.
Abell 1835 IR1916 is a fascinating astronomical object located in the Abell 1835 galaxy cluster, which is situated about 2.7 billion light-years away from Earth in the constellation Pegasus. It is notable for being a strongly lensed galaxy, discovered through the gravitational lensing effect caused by the massive galaxy cluster in front of it.
As of my last knowledge update in October 2023, there is no widely recognized or established term "Cryptomenysis Patefacta" in the fields of cryptography, cryptocurrency, or any related domains. It may potentially be a niche term, a misspelling, a newly coined phrase, or a specific concept that has emerged after my last update.

A "fascinator" is a type of headpiece often worn by women, typically associated with formal occasions like weddings, horse races, and other events where dressing up is customary. It usually consists of a decorative design that may include feathers, flowers, or netting, and is often attached to the hair with a headband, clip, or comb.
Nikolaos Bourbakis is a notable figure in the field of computer science, particularly recognized for his contributions to artificial intelligence, robotics, and computer vision. His work often focuses on interdisciplinary approaches, integrating concepts from various domains such as biology and engineering. The exact details regarding his contributions can vary widely depending on specific contexts, so it's advisable to refer to his research papers and publications for in-depth information.
A cryptogram is a type of puzzle that consists of a piece of plaintext that has been encrypted through a simple substitution cipher, where each letter in the original message is replaced by a different letter. The goal of the cryptogram is to decode the encrypted message using logical reasoning, frequency analysis, and pattern recognition. Typically, cryptograms appear as short quotes, proverbs, or phrases, and they are often presented as a fun challenge in newspapers, puzzle books, and online.
Barsoum elements, also known as "Barsoum's elements," refer to a specific type of finite element used in engineering and computational mechanics, particularly in the analysis of structures. Named after the engineer and researcher M. A. Barsoum, these elements are designed for the analysis of complex structural behaviors, including large deformations, nonlinear materials, and dynamic effects.
In physics, particularly in the context of relativity, the term "rest frame" refers to a reference frame in which an object is at rest. In this frame, the object is not moving relative to the observer, and all measurements (like distance, time, and energy) can be made without the complications introduced by motion. For example, consider a person standing still while observing a car that is moving past them.
Hesse, or Hessen in German, is one of the 16 federal states (Bundesländer) of Germany. It is located in the central part of the country and is known for its diverse geography, which includes mountains, forests, and rivers. The state capital is Wiesbaden, while its largest city is Frankfurt am Main, which is a major financial center and hosts the European Central Bank.
CER-20 typically refers to a specific guideline or resource related to the field of biopharmaceuticals, particularly in the context of the European Medicines Agency (EMA) or similar organizations. However, it’s possible that the acronym can have other meanings in different contexts.
Paul Painlevé (1863–1933) was a notable French mathematician known for his contributions to various fields, including mathematics, physics, and applied mathematics. He is particularly recognized for his work in the theory of differential equations and special functions. Painlevé is most famous for the "Painlevé equations," which are a set of six nonlinear ordinary differential equations that have important implications in various areas of mathematical physics.
Diffusion creep is a mechanism of deformation that occurs in materials, particularly in solids under high temperature and stress conditions. It is characterized by the movement of atoms or vacancies within the crystal lattice of a material, allowing it to deform without the need for dislocation movement, which is a more conventional mechanism of plastic deformation. The process occurs through the diffusion of atoms in the lattice, which can happen via two main types: grain boundary diffusion and lattice diffusion.
Cribbage statistics typically refer to the analysis of game data related to the card games of Cribbage. Cribbage itself is a popular card game that involves two players (or teams) scoring points through various combinations of cards. The game uses a unique scoring board and has specific rules for scoring, both during play and through the use of a "crib" (a separate hand of cards set aside for additional scoring).
Forensic polymer engineering is a specialized field that combines principles of polymer science, materials science, and forensic investigation to analyze and interpret the properties and behaviors of polymer materials in legal or investigative contexts. This discipline is often employed in cases involving polymer products, such as plastics, composites, and elastomers, particularly when failure, damage, or degradation occurs.

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.
