Thermal conductivity measurement refers to the process of determining a material's ability to conduct heat. Thermal conductivity (\(k\)) is a physical property that quantifies how well a material can transfer thermal energy through conduction. It is an important parameter in various fields including material science, engineering, building construction, and thermal management.
In topology, a wedge sum is a specific way of combining two or more topological spaces into a single space. The construction involves taking a collection of spaces and identifying a single point from each space. The basic idea is as follows: 1. **Choose Spaces**: Consider two or more topological spaces, say \(X_1, X_2, \ldots, X_n\).
FreeFem++ is a free, open-source software platform designed for the numerical solution of partial differential equations (PDEs) using finite element methods (FEM). It is particularly popular for its ease of use and flexibility, facilitating rapid prototyping and implementation of complex numerical simulations. Key features of FreeFem++ include: 1. **User-Friendly Syntax**: It offers a high-level programming language that allows users to describe geometries, variational forms, and boundary conditions succinctly and intuitively.
James Thomas Beale is not a widely recognized public figure or concept, as of my last knowledge update in October 2023. However, the name may refer to various individuals, possibly in different contexts such as academia, literature, or local history.
Weight loss refers to the process of reducing body weight, typically by decreasing body fat. It can occur intentionally through various methods such as dietary changes, increased physical activity, or behavioral modifications, or unintentionally due to factors like illness or nutritional deficiencies. ### Key Aspects of Weight Loss: 1. **Energy Balance**: Weight loss generally occurs when the number of calories burned exceeds the number of calories consumed. This is often referred to as a caloric deficit.
A flood bypass, often referred to as a flood bypass channel or flood relief channel, is a designated pathway or channel designed to divert excess water from a river, creek, or other body of water during conditions of flooding. The primary purpose of a flood bypass is to mitigate the risk of flooding in urban areas, agricultural zones, or regions where floodwaters could cause significant damage to infrastructure, homes, and ecosystems.
The "Art of Memory," also known as "mnemonics," refers to techniques and strategies used to enhance memory and improve the ability to retain and recall information. This practice dates back to ancient civilizations and is rooted in the idea that the mind can create vivid mental images and associations to help remember information more effectively.
"The Schoolmaster's Assistant: Being a Compendium of Arithmetic Both Practical and Theoretical" is a mathematical textbook written by the American educator and mathematician Thomas Dilworth, first published in the 18th century (specifically in 1765). The book was designed as a comprehensive guide for teaching arithmetic, providing a wide range of mathematical concepts, techniques, and problem-solving methods.
Peter Hayes is a diplomat who has served in various capacities in the field of international relations. His work often involves engagement with different countries and international organizations to promote diplomacy and address global issues. Specific details about his career, roles, and contributions may vary, and for the most up-to-date and comprehensive information, it's best to consult credible sources or official websites related to diplomacy and international affairs.
Peter J. Denning is a prominent figure in the field of computer science, particularly known for his contributions to computer systems, networking, and operating systems. He has authored numerous influential papers and books and has served in various academic and professional capacities throughout his career. Denning is recognized for his work on the concept of "working sets," which helps in managing memory in operating systems. He has also been involved in various foundational aspects of computing and education in the field.
"The Seventh Decade: The New Shape of Nuclear Threat" is a book written by journalist and author Daniel Ellsberg, published in 2007. In this work, Ellsberg, who is famous for leaking the Pentagon Papers, examines the evolving landscape of nuclear weaponry and the associated risks in the post-Cold War era.
Peter Norvig is an American computer scientist and a prominent figure in the field of artificial intelligence (AI). He is known for his work on natural language processing, machine learning, and general AI research. Norvig has served as the Director of Research at Google, where he has contributed to various projects related to AI and machine learning.
A gatehouse in the context of waterworks typically refers to a structure that is part of a hydrological system, such as a dam, reservoir, or water treatment facility. It usually serves multiple purposes, including: 1. **Control of Water Flow:** Gatehouses often contain gates or valves that can be opened or closed to control the flow of water into and out of a water body. This control is crucial for managing water levels, maintaining flow rates, and ensuring safe water supply.
Petersen's theorem refers to a specific result in graph theory related to the structure of graphs. It states that every cubic vertex-transitive graph that is not bipartite contains a Hamiltonian cycle. A graph is cubic if every vertex has degree 3 (i.e., each vertex is connected to exactly three other vertices).

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.
