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'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, 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.
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 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 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.
As of my last knowledge update in October 2023, Cyclone Oratia refers to a tropical cyclone that was active in the region of the South Pacific. Cyclones like Oratia typically bring strong winds, heavy rains, and can lead to significant coastal damage, flooding, and disruptions. The impacts of such cyclones can vary based on their intensity and trajectory.
Cyclone Xavier was a tropical cyclone that formed in the southwestern Indian Ocean in 2017. It was known for its intensity as it impacted several regions, particularly around the island nations of Madagascar and Mauritius. Cyclone Xavier developed in January 2017 and caused significant weather disturbances, including heavy rains and strong winds. The cyclone affected local communities, leading to damage to infrastructure and agriculture, as well as prompting evacuations in vulnerable areas.
A European windstorm refers to a weather phenomenon characterized by strong winds, often accompanied by heavy rain, thunderstorms, and sometimes snowfall, that affects parts of Europe, particularly during the autumn and winter months. These storms can develop as a result of low-pressure systems forming over the North Atlantic Ocean and moving towards Europe.
Bridgefy is a communication application designed to enable users to send and receive messages without requiring an internet connection or mobile data. It uses Bluetooth and mesh networking technology to facilitate communication directly between devices in close proximity. This makes it particularly useful in situations where cellular networks may be unreliable or unavailable, such as during protests, natural disasters, or in remote areas. Bridgefy allows users to send text messages, photos, and other types of content to one another even when they are not connected to the internet.
The Great Storm of 1703 was one of the most severe storms ever recorded in England. It occurred from November 26 to November 27, 1703, and was notable for its ferocity and the extensive damage it caused. The storm is estimated to have reached hurricane-force winds, with gusts exceeding 100 miles per hour (160 km/h), and it primarily affected southern England.
St. Peter's Flood refers to a severe storm surge that occurred in surrounding coastal regions, particularly affecting the Netherlands and the United Kingdom, primarily around the time of the feast of Saint Peter (June 29) or during the winter months.
Storm Desmond was a powerful and severe winter storm that affected parts of the United Kingdom and Ireland in early December 2015. It was notable for causing widespread flooding, particularly in northern England, including areas like Cumbria and Lancashire. The storm brought heavy rainfall, high winds, and severe weather conditions, leading to significant disruptions, including road closures, transport delays, and power outages.
Storm Emma was a weather event that affected parts of Europe, particularly the United Kingdom and Ireland, in early March 2018. It was caused by a combination of a cold Arctic air mass and an intense low-pressure system that brought significant snowfall and extremely cold temperatures. The storm resulted in heavy snowfall, blizzard conditions, and extreme weather, leading to widespread travel disruptions, school closures, and power outages. In some areas, drifts of snow reached several meters.

Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
