Google bombing is a technique used to manipulate search engine results in order to make a particular website or page appear higher in search rankings for specific keywords or phrases, usually through the strategic use of backlinks and anchor text. This often involves a group of people linking to a particular site using the same phrase, in an effort to associate that phrase with the website in Google's algorithms. One of the most famous examples of Google bombing occurred in the mid-2000s when users linked to the George W.
Mpemba effect by Wikipedia Bot 0
The Mpemba effect is an observed phenomenon where hot water can freeze faster than cold water under certain conditions. Named after Tanzanian student Erasto Mpemba, who noticed this effect in the 1960s, the effect has intrigued scientists and led to various hypotheses explaining why it occurs.
The Preisach model of hysteresis is a mathematical representation used to describe and analyze the hysteretic behavior of materials and systems. It is particularly relevant in the study of ferromagnetic and ferroelectric materials, where the relationship between external inputs (like magnetic or electric fields) and outputs (like magnetization or polarization) exhibits a non-linear behavior that depends on the history of the applied field.
Wetting by Wikipedia Bot 0
Wetting refers to the ability of a liquid to maintain contact with a solid surface, resulting from adhesive forces between the liquid and the solid. This phenomenon is particularly important in various fields such as chemistry, materials science, and biology. When a liquid is poured onto a solid surface, the extent to which the liquid spreads out or forms droplets depends on the balance between cohesive forces (the forces holding the liquid molecules together) and adhesive forces (the forces between the liquid molecules and the surface).
Dynamic insulation is a concept that involves a building envelope designed to adapt to varying environmental conditions, aiming to optimize thermal performance while using less energy. Unlike traditional insulation methods that provide a static barrier to heat transfer, dynamic insulation systems actively respond to changes in temperature and humidity. Key features of dynamic insulation can include: 1. **Responsive Materials**: These materials can change their thermal properties based on external conditions, such as temperature and moisture levels.
Relative volatility is a measure used in the field of chemical engineering, particularly in distillation and separation processes, to quantify the ease with which one component in a mixture can be separated from another component. It is defined as the ratio of the vapor pressures of two components in a liquid mixture.
Storm Barra by Wikipedia Bot 0
Storm Barra was a significant weather event that affected parts of Europe in December 2021. It was classified as a named storm by the UK Met Office and brought heavy rain, strong winds, and severe weather conditions to various regions, particularly in the UK and Ireland. The storm led to widespread disruption, including power outages, travel disruptions, and property damage due to high winds and flooding.
Heat equation by Wikipedia Bot 0
The heat equation is a fundamental partial differential equation that describes how the distribution of heat (or temperature) in a given region evolves over time. It is a mathematical model used in various fields such as physics, engineering, and finance to study heat conduction, diffusion, and other related processes.
The heat transfer coefficient is a measure of the ability of a material or surface to transfer heat between two fluids or between a fluid and a solid surface. It quantifies the rate of heat transfer per unit area per unit temperature difference between the two entities in contact.
Loop heat pipe by Wikipedia Bot 0
A Loop Heat Pipe (LHP) is a highly efficient thermal management system that is used to transfer heat from a heat source to a heat sink over relatively long distances with minimal temperature drop. It works through a passive mechanism, utilizing the principles of phase change and capillary action to circulate a working fluid. ### Key Components of a Loop Heat Pipe: 1. **Evaporator**: This is where the heat is absorbed from the heat source.
Thermal resistance is a measure of a material's ability to resist the flow of heat. It quantifies how well a material or a system conducts thermal energy and is often used in the context of thermal insulation and heat transfer.
The concept of entropy has a rich history that spans various fields, including thermodynamics, statistical mechanics, information theory, and more. Here’s a broad overview of its development: ### Early Ideas 1. **Carnot and Thermodynamics (1824)**: The origins of entropy can be traced back to the work of French physicist Sadi Carnot, who studied the efficiency of engines.
Clausius theorem by Wikipedia Bot 0
Clausius's theorem is a fundamental principle in thermodynamics that relates to the second law of thermodynamics. It is named after the German physicist Rudolf Clausius, who made significant contributions to the field. In essence, Clausius's theorem states that for any reversible cyclic process, the increase in the entropy of a system is equal to the heat transferred into the system divided by the temperature at which the heat transfer takes place.
Neumann's law by Wikipedia Bot 0
Neumann's Law, often referred to in the context of thermodynamics and heat transfer, is typically associated with the behavior of heat conduction in materials. It states that the heat flux out of a material is proportional to the temperature gradient within that material, usually expressed mathematically by Fourier's law of heat conduction. In a broader context, the law may also refer to various principles in physics and mathematics related to von Neumann's work, such as in quantum mechanics or game theory.
The term "triple product rule" can refer to different concepts in mathematics and physics, depending on the context. Here are two common interpretations: 1. **In Vector Calculus (Triple Scalar Product)**: The triple product often pertains to the scalar triple product of three vectors \( \mathbf{a}, \mathbf{b}, \mathbf{c} \) in three-dimensional space.
Sting jet by Wikipedia Bot 0
A Sting Jet is a meteorological phenomenon associated with certain types of storms, particularly extratropical cyclones. It refers to a narrow, fast-moving area of strong winds that descends from a cloud base to the surface, typically occurring within heavy rain, thunderstorms, or severe weather systems. Sting Jets are most commonly identified in the context of the "sting jet" mechanism associated with the development of intense low-pressure systems.
The Christmas Flood of 1717 refers to a significant series of coastal flooding events that occurred in several regions of northern Europe, particularly in the Netherlands, Germany, and Denmark, around Christmas time in December 1717. The flooding was caused by a combination of an intense storm, high tides, and the effects of land subsidence in the low-lying areas of these countries. The storm that triggered the flooding was particularly fierce, leading to exceptionally high sea levels.
Cyclone Berit by Wikipedia Bot 0
Cyclone Berit was a significant weather event that occurred in late 2018. It was a strong extratropical cyclone that affected parts of Northern Europe, particularly Scandinavia and the British Isles. The cyclone brought heavy rainfall, strong winds, and disruption to transportation and infrastructure in various regions. Cyclone Berit was notable for its impact on weather patterns in Europe, leading to severe weather warnings and exceptional conditions in some areas.
Cyclone Carmen by Wikipedia Bot 0
Cyclone Carmen was a tropical cyclone that occurred in the South Pacific in early 2019. Specifically, it formed in February 2019 and impacted several areas, including parts of Fiji and other islands in the region. Cyclone Carmen was notable for its intensity and the adverse weather conditions it brought, including heavy rainfall, high winds, and potential flooding. The cyclone was part of the annual tropical cyclone season which typically affects the South Pacific from November through April.

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.
