The Alikhanian–Alikhanov spectrometer is a type of device used in nuclear and particle physics for detecting and analyzing gamma rays and other forms of electromagnetic radiation. Named after physicists A.I. Alikhanian and A.A. Alikhanov, the spectrometer typically leverages scintillation detectors or other detection technologies to measure the energy and intensity of radiation emitted during various nuclear processes.
Resonant Inelastic X-ray Scattering (RIXS) is an advanced spectroscopic technique used primarily in the study of the electronic and magnetic properties of materials. It combines elements of X-ray scattering and spectroscopy to provide insights into the excitations of a system, such as phonons, magnons, and electronic excitations, often with a high level of energy resolution.
Collinder 228 is an open star cluster located in the constellation of Cassiopeia. It was cataloged by the Swedish astronomer Per Collinder in 1931 as part of his investigation of open clusters. Open clusters are groups of stars that are gravitationally bound and formed from the same molecular cloud, typically containing a few dozen to a few thousand stars. Collinder 228 is relatively young and is notable for its stars being relatively hot and bright.
The weather in 2015 was marked by a variety of significant climate events and patterns around the world. Some key highlights include: 1. **El Niño**: 2015 was one of the strong El Niño years, leading to abnormal weather patterns globally. El Niño typically causes warmer ocean temperatures in the Pacific, influencing weather in many regions. 2. **Record Heat**: Many parts of the world experienced record-breaking temperatures.
Coronal rain refers to a phenomenon observed in the solar corona, which is the outermost layer of the Sun's atmosphere. It occurs when plasma, typically in the form of cool, dense strands of solar material, falls back to the Sun after being ejected into the corona. This material often originates from solar prominences or flares, where magnetic field lines in the Sun's atmosphere channel the cooler, denser plasma into loops.
The Old Farmer's Almanac is an annual publication that has been in circulation since 1792, making it one of the oldest continuously published periodicals in North America. It is well-known for its long-range weather forecasts, gardening tips, and various articles related to farming, gardening, cooking, and home remedies. The Almanac traditionally includes information such as planting calendars, astronomical data (like moon phases and eclipses), and recipes, along with anecdotes and folklore.
Stormy Marmot is a popular online persona and a social media account that features various content, including political commentary, memes, and progressive viewpoints. The account is known for its humorous and often satirical take on current events, politics, and social issues. The username "Stormy Marmot" has gained a following on platforms like Twitter, where it engages with users through witty remarks and memes related to contemporary political discourse.
The British Valve Association (BVA) is an industry organization in the United Kingdom that represents manufacturers and suppliers of valves, actuators, and related products used in fluid control applications. The BVA aims to promote the interests of its members, enhance the industry standards, and provide a platform for collaboration and knowledge sharing among its members and stakeholders.
A **pistonless pump** is a type of pump that operates without the use of pistons to move fluids. Unlike traditional piston pumps, which use a reciprocating motion to create pressure and flow, pistonless pumps rely on other mechanisms, such as rotary movement or diaphragm action, to achieve fluid movement. ### Types of Pistonless Pumps 1.
Valve manufacturers are companies that design, produce, and supply various types of valves used in different industries for controlling the flow of fluids (liquids and gases). Valves play a critical role in numerous applications, including water supply systems, chemical processing, oil and gas, pharmaceuticals, HVAC systems, and more. There are several types of valves, including: 1. **Gate Valves**: Used for on/off control of flow; they are either fully open or closed.
A valve actuator is a device that automatically opens, closes, or regulates a valve based on a controlling signal. It serves as a key component in various systems where the flow of liquids, gases, or steam needs to be controlled. Actuators can be powered by various energy sources, including: 1. **Electric**: These actuators use electric motors to operate the valve. They are commonly used for applications that require precise control and can be integrated with automated control systems.
Military robots are unmanned systems designed for various defense and combat roles. These robots can be remotely controlled or operate autonomously, utilizing advanced technologies in robotics, artificial intelligence, sensors, communication, and navigation. Military robots can serve a wide range of purposes, including: 1. **Reconnaissance and Surveillance**: Drones equipped with cameras and sensors gather intelligence over hostile areas without risking human lives.
A screw is a simple machine that converts rotational motion into linear motion. It consists of a helical ridge or thread wrapped around a cylindrical shaft. When the screw is turned, the helical thread moves along the axis of the cylinder, allowing the screw to be driven into materials, such as wood or metal, or to lift objects. Screws are widely used in various applications, including fastening, lifting, and anchoring.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
