Farley–Buneman instability is a phenomenon observed in plasmas, particularly in the context of ionospheric and magnetospheric physics. It refers to a type of instability that arises in a collisional plasma when there is a relative drift between positive ions and electrons. This relative motion creates an electric field that can lead to the growth of density fluctuations or waves.
A Magnetohydrodynamic (MHD) drive is a method of propulsion that uses the principles of magnetohydrodynamics, which is the study of the behavior of electrically conducting fluids in the presence of magnetic fields. In an MHD system, a conducting fluid (such as plasma, seawater, or liquid metals) is propelled by electromagnetic forces generated by the interaction between the fluid's motion and an external magnetic field.
Nuclear pulse propulsion is a theoretical spacecraft propulsion method that uses nuclear explosions to generate thrust. The basic concept involves detonating a series of nuclear bombs behind a spacecraft, which pushes it forward. This idea was notably explored in the 1950s and 1960s in a project called Project Orion. ### How It Works: 1. **Nuclear Pulses**: The spacecraft would carry a payload of nuclear bombs.
Plasma stealth by Wikipedia Bot 0
Plasma stealth refers to the use of plasma technology to reduce the radar cross-section (RCS) of an object, such as an aircraft or a spacecraft, making it less detectable by radar systems. This concept leverages the properties of plasma—ionized gas that can conduct electricity and respond to electromagnetic fields. Plasma stealth works on the principle that a layer of plasma can absorb or deflect radar waves, breaking up the radar signature of the object.
Moruroa by Wikipedia Bot 0
Moruroa is an atoll located in the South Pacific Ocean, and it is part of French Polynesia. It is known primarily for its association with French nuclear testing during the 20th century. From 1966 to 1996, France conducted numerous nuclear tests at Moruroa, which led to significant environmental and health concerns among local populations and environmentalists. The atoll itself consists of a number of islands surrounded by a large lagoon.
Plasma window by Wikipedia Bot 0
A plasma window is a device that uses a stream of ionized gas (plasma) to create a boundary between two different environments, such as a vacuum and an atmosphere. The concept leverages the properties of plasma, which can conduct electricity and support electromagnetic fields, to maintain stability and integrity between these two states without the need for a physical barrier, like a wall or a membrane. **Key characteristics and applications of plasma windows include:** 1.
Lower hybrid oscillations (LHO) are a type of plasma oscillation that occur in magnetized plasmas, typically in the context of fusion devices or space plasmas. These oscillations arise from the coupling of electron plasma waves and ion acoustic waves in the presence of a magnetic field. ### Key Characteristics: 1. **Frequency Range**: Lower hybrid oscillations occur at frequencies typically between the electron cyclotron frequency and the ion cyclotron frequency.
Magnetosonic wave by Wikipedia Bot 0
Magnetosonic waves, also known as magnetosonic waves or MHD (magnetohydrodynamic) waves, are a type of wave that occurs in magnetized plasmas, which are ionized gases that are influenced by magnetic fields. These waves are a combination of sound waves and magnetic waves, propagating through a medium where both gas pressure and magnetic pressure play significant roles.
Quantum Break by Wikipedia Bot 0
"Quantum Break" is an action-adventure video game developed by Remedy Entertainment and published by Microsoft Studios. Released in April 2016 for Xbox One and Windows PC, it combines gameplay with live-action television episodes to create a narrative-driven experience. The game's story revolves around a character named Jack Joyce, who gains time-manipulation abilities after a time travel experiment goes wrong.
Magnetohydrodynamic (MHD) turbulence is a complex field of study that combines aspects of fluid dynamics and magnetohydrodynamics, which is the behavior of electrically conducting fluids in the presence of a magnetic field. MHD turbulence is particularly relevant in astrophysical contexts, such as in the behavior of plasmas in stars, galaxies, and interstellar space, as well as in industrial processes involving liquid metals and other conducting fluids.
Anoxic events by Wikipedia Bot 0
Anoxic events refer to periods in which specific waters, regions, or environments become depleted of oxygen, leading to severe conditions for aquatic life and other organisms that rely on oxygen for survival. "Anoxic" specifically means lacking oxygen (from the Greek "an-" meaning "without" and "oxia" meaning "oxygen").
Geotraces by Wikipedia Bot 0
GEOTRACES is an international research program aimed at understanding the trace elements and isotopes in the ocean and their roles in marine biogeochemistry. Launched in 2004, the program focuses on the distribution and cycling of trace elements such as metals and nutrients, which are essential for marine organisms and ecological processes but are often present in very low concentrations.
Hypoxia, in an environmental context, refers to a condition in which there is a deficiency of oxygen in a particular area, typically in aquatic environments such as oceans, lakes, or rivers. This can lead to significant ecological impacts, affecting the survival of fish and other aquatic organisms that rely on dissolved oxygen for respiration.
Oligosaprobe by Wikipedia Bot 0
An "oligosaprobe" is a term often used in microbiology and ecology to describe a specific type of organism that requires very low concentrations of organic matter to thrive. Oligosaprobic organisms typically inhabit environments with low levels of pollution and organic enrichment, such as clean streams and lakes. These organisms are contrasted with "eutrophic" organisms, which are adapted to environments rich in nutrients and organic material.
Sea salt aerosol by Wikipedia Bot 0
Sea salt aerosol refers to tiny particles or droplets that originate from the ocean and are composed primarily of salt, mainly sodium chloride (NaCl), along with a mix of other compounds such as magnesium, calcium, and potassium salts. These aerosols are created through various processes, primarily the breaking of ocean waves which generates bubbles that burst at the surface, releasing salt particles into the atmosphere. Sea salt aerosols play a significant role in the Earth's climate and atmospheric chemistry.
Total boron by Wikipedia Bot 0
Total boron typically refers to the total concentration of boron present in a sample, which can include various forms such as boric acid, borate, and other boron compounds. In environmental science, chemistry, and geological studies, measuring total boron is important for understanding its presence and effects in ecosystems, water sources, and soil.
The Urey–Bigeleisen–Mayer equation is a formula used in physical chemistry and isotopic chemistry to relate the equilibrium constants of chemical reactions involving isotopes to the differences in their vibrational energies. It provides a way to understand and quantify the isotopic effects that occur in chemical reactions, particularly the fractionation of isotopes. This equation is particularly useful in studying the behavior of molecules containing different isotopes of elements, such as hydrogen, carbon, nitrogen, and oxygen.
Oceanographical terminology refers to the specialized vocabulary and concepts used in the field of oceanography, which is the study of the ocean and its various components, including marine ecosystems, ocean currents, physical and chemical properties of seawater, and geological features. This terminology is essential for scientists, researchers, and professionals in the field to communicate effectively about ocean-related topics.
Bottom water by Wikipedia Bot 0
Bottom water refers to the colder, denser water that resides at the bottom of a body of water, such as an ocean, sea, or lake. This water is generally characterized by its lower temperature and higher salinity compared to surface water. In oceanography, the term is often used to describe water that is found in deep ocean basins, particularly in the context of thermohaline circulation, where differences in temperature and salinity drive water movement.

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.
