The term "statcoulomb" refers to a unit of electric charge from the centimeter-gram-second (CGS) system, specifically in the electrostatic system of units (also known as the "electrostatic CGS" system). The statcoulomb is defined as the amount of charge that produces a force of one dyne on each of two point charges separated by a distance of one centimeter in a vacuum.
Foe (unit) by Wikipedia Bot 0
In the context of measurement, a "foe" is a unit of energy, specifically used to quantify large amounts of energy, typically in astrophysics. One foe is defined as \(10^{44}\) joules. The term is often used to describe the energy output of astronomical events, such as supernovae, or the total energy generated by a star over its lifetime. The name "foe" is derived from the phrase "five-oh," signifying \(10^{44}\).
Quad (unit) by Wikipedia Bot 0
A "quad" is a unit of energy commonly used in the fields of energy production and consumption. It stands for "quadrillion British thermal units" (BTUs). To give you a sense of scale: - 1 quad = \(10^{15}\) BTUs In terms of other energy units, 1 quad is approximately equal to: - 1.055 exajoules (EJ) - 293.
Fixture unit by Wikipedia Bot 0
A fixture unit is a measurement used in plumbing engineering to quantify the contribution of various plumbing fixtures to the overall demand for water in a building. This concept helps in determining the appropriate size of water supply and drainage systems. Each plumbing fixture (e.g., sinks, toilets, showers, bathtubs) is assigned a specific number of fixture units based on its typical flow rate and usage patterns. The fixture unit values are standardized and can vary by local codes or regulations.
Standard Cubic Feet per Minute (SCFM or sometimes just CFM) is a unit of measurement used to express the flow rate of gases. It indicates the volume of gas that flows through a specific point in a system per minute, standardized to certain conditions of temperature and pressure. The term "standard" refers to the conditions under which the volume is measured, which are typically set at a specific temperature (often 60°F or 15.
Becquerel by Wikipedia Bot 0
Becquerel (symbol: Bq) is the SI unit of radioactivity. It measures the activity of a quantity of radioactive material, specifically the number of disintegrations (or decay events) that occur in a sample per second. One becquerel is defined as one disintegration per second. The unit is named after Henri Becquerel, a French physicist who discovered radioactivity in 1896.
Lux by Wikipedia Bot 0
"Lux" can refer to several different concepts depending on the context. Here are a few: 1. **Illumination/Light Measurement**: In scientific terms, "lux" is a unit of measurement for illuminance, which quantifies the amount of light that is received on a surface area. One lux is equal to one lumen per square meter. It is commonly used in fields related to lighting design and architecture.
Bolt (cloth) by Wikipedia Bot 0
"Bolt" in the context of cloth refers to a length of fabric that is typically rolled onto a spool or a bolt. It is often used in the textile industry to indicate a standard measure of fabric that can be easily transported and sold. The length of a bolt can vary, but common lengths are 10, 25, or 50 yards, depending on the type of fabric and the manufacturer.
Chi (unit) by Wikipedia Bot 0
The Chi (χ) is a unit used in the field of fluid dynamics and is commonly associated with turbulent flow analysis. Specifically, it can represent a non-dimensional number that characterizes turbulence intensity or the behavior of certain properties in turbulent flows. In the context of turbulence, Chi can also refer to the turbulent mixing characteristics or other fluid properties where a non-dimensional number helps in understanding the physical behavior of the flow.
A **Device-Independent Pixel (DIP)** is a unit of measurement used in digital graphics and user interface design that provides a way to measure sizes and positions in a way that is independent of the actual display resolution of a device. This concept is particularly important when creating applications and interfaces that need to render consistently across a wide range of devices with varying screen sizes and pixel densities.
Endaze by Wikipedia Bot 0
As of my last knowledge update in October 2023, "Endaze" does not refer to a widely recognized concept, brand, or term. It is possible that it could be a name of a company, product, or concept that has emerged after that date, or it may not have gained wide popularity or recognition.
Geographical mile by Wikipedia Bot 0
A geographical mile, also known as a nautical mile, is a unit of measurement used primarily in maritime and air navigation. It is defined as the distance corresponding to one minute of latitude along a meridian. Since the Earth is approximately a sphere, a geographical mile takes into account the curvature of the Earth. One nautical mile is equal to: - 1,852 meters - 1.15078 statute miles (the miles most commonly used on land).
Kadem by Wikipedia Bot 0
Kadem, often referred to in the context of Kademlia, is a type of distributed hash table (DHT) protocol used in peer-to-peer networking. Kademlia is designed for decentralized network applications, allowing nodes to efficiently locate and store data across a dispersed network without a central server.
Ken (unit) by Wikipedia Bot 0
A "ken" is a traditional unit of measurement that is commonly used in parts of East Asia. Specifically, in Japan, one ken is typically equivalent to about 1.82 meters (approximately 6 feet). It is often used in the context of measuring the dimensions of buildings, particularly in the context of traditional Japanese architecture, where rooms are often designed based on the number of kens.
Optical unit by Wikipedia Bot 0
An optical unit is a standard measure used in optics to quantify characteristics of optical systems, such as lenses, microscopes, or cameras. It can refer to a range of concepts depending on the context, including: 1. **Lens Focal Length**: This is a crucial optical unit, measured in millimeters (mm), that describes the distance from the lens at which parallel rays of light converge to a point (the focal point).
Paris point by Wikipedia Bot 0
The term "Paris Point" can refer to different concepts depending on the context. One common interpretation is related to the field of geometry or topology, specifically concerning the concept of “points at infinity” or in projective geometry. However, it is not a widely recognized term in these disciplines. Alternatively, "Paris Point" might also refer to specific locations, landmarks, or historical events associated with Paris, France.
Rack unit by Wikipedia Bot 0
A Rack Unit, often abbreviated as "U" (or sometimes just "RU"), is a standardized unit of measurement used to describe the height of equipment designed to be mounted in a standard 19-inch server rack or equipment rack. One Rack Unit is equivalent to 1.75 inches (44.45 mm) in height. Equipment that is mounted in racks, such as servers, networking gear, and storage devices, is typically specified in terms of Rack Units.
Seconds pendulum by Wikipedia Bot 0
A "seconds pendulum" is a type of pendulum that has a period of exactly two seconds—one second to swing in one direction and one second to return to its starting point. This means it completes a full oscillation (back and forth) in two seconds. The period of a simple pendulum is influenced by its length and the acceleration due to gravity.
Walking distance measure refers to a method of quantifying the distance that a person can walk from a specific point, typically considering the path taken along streets, sidewalks, or trails. It is often used in urban planning, geographic information systems (GIS), transportation studies, and healthcare to assess accessibility to various amenities, services, or locations.

Pinned article: ourbigbook/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.
