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.
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 \(10^{44}\).
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.
The term "Gunta" can refer to different things depending on the context: 1. **Land Measurement**: In some South Asian countries, such as India and Nepal, a "gunta" (or "gunta") is a traditional unit of area measurement. It is commonly used to measure land, particularly in rural regions. One gunta is equivalent to approximately 1,089 square feet or about 0.0405 acres.
Ankanam is a term derived from Sanskrit and is often used in the context of Hindu astrology and numerology. It refers to a method of divination or calculation that involves numerical analysis based on individuals' birth details. In this system, various numbers are derived from names, birth dates, and other significant factors to understand personality traits, destiny, and potential life paths.
A "manzana" is a unit of area commonly used in Central America, particularly in countries like Honduras, El Salvador, and Nicaragua. The size of a manzana can vary slightly depending on the country, but it is generally accepted to be approximately 0.7 acres or 0.28 hectares. In some regions, it is defined as 6,000 square meters.
The term "turnover number" can refer to a few different concepts depending on the context in which it is used. Here are a couple of common interpretations: 1. **In Finance and Business**: Turnover number often relates to the amount of business conducted by a company during a specific period. It can refer to total revenues or the total sales generated by the company. In this context, a higher turnover can indicate a more successful business operation.
The Oechsle scale is a measurement used primarily in the wine industry, particularly in Germany, to determine the must weight of grape juice before fermentation. It reflects the sugar content present in the grapes, which is important for assessing the potential alcohol content of the resulting wine. The scale is named after the German wine pioneer Georg Oechsle, who developed it in the 19th century.
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.
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.
"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.
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 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).
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).
"Arroba" is a term that has several meanings depending on the context: 1. **Unit of Measurement**: In some Latin American countries and in historical contexts, an "arroba" is a unit of weight. It traditionally equals about 25 pounds (approximately 11.34 kilograms) in the United States customary system. It has been used for measuring goods such as food and produce.
"Dutch cask" typically refers to a type of barrel or cask used for aging spirits, particularly whiskey or other alcoholic beverages, in the Netherlands or in the style commonly associated with Dutch production methods. However, the term can also be associated with a few specific contexts: 1. **Dutch Gin (Jenever)**: In the context of Jenever, the traditional Dutch gin, "Dutch cask" might refer to the barrels used for aging this spirit.
A myriagram is a unit of mass in the metric system equivalent to 10,000 grams. It is not commonly used in everyday measurement but can be useful in specific scientific contexts where larger mass units are needed. The myriagram is part of the larger metric system, where one myriagram equals 10 kilograms, as 1 kilogram is defined as 1,000 grams.
A proof mass, often referred to in the context of mechanical systems, is a mass used to provide a known weight for testing or calibration purposes. It is commonly utilized in various applications, such as in vibration testing, sensor calibration, and structural analysis. In the context of vibration testing, for instance, a proof mass can be attached to a structure or a sensor to simulate the effects of real loads, helping engineers assess how a system behaves under different conditions.

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.
