"DICE" can refer to different things depending on the context. Here are a few common meanings: 1. **Gaming Dice**: In the context of board games, tabletop role-playing games, and other forms of gaming, "dice" are small, typically cube-shaped objects marked with numbers or symbols on their faces. Players use them to generate random numbers in games, often to determine outcomes, movement, or actions.
PKS 2014-55, sometimes referred to as PKS 2014-55 or 2MASS J20160731-5546120, is a blazar, which is a type of active galactic nucleus (AGN) exhibiting strong variable emissions across the electromagnetic spectrum, including radio, optical, and gamma-ray wavelengths. Blazars are characterized by their relativistic jets that are oriented closely along our line of sight.
W0410-0913 could refer to a variety of things depending on the context, but it is not a widely recognized acronym or term as of my last knowledge update in October 2023. It may represent a model number, a code related to a specific product, a project designation, or even a geographical code.
The term "stellar halo" refers to a roughly spherical region surrounding a galaxy, composed of stars, globular clusters, and dark matter. The stellar halo typically contains older stars and is less dense than the main disk of the galaxy. In our Milky Way, for instance, the stellar halo extends well beyond the visible disk and is thought to be a remnant of the early stages of galaxy formation and accretion of smaller galaxies and star clusters.
The term "Probability of Kill" (Pk) is a concept used primarily in military operations and defense analysis. It refers to the likelihood or probability that a specific weapon system will successfully destroy its intended target. Pk is typically expressed as a percentage, indicating the effectiveness of a weapon against a given threat. Pk is influenced by various factors, including: 1. **Weapon Characteristics**: The design, accuracy, and lethality of the weapon.
The term "regular economy" is not commonly used in economic literature, and its meaning can vary based on context. However, it may refer to a stable and conventional form of economic activity characterized by consistent patterns of production, distribution, and consumption of goods and services.
The multiple gamma function, often denoted as \( \Gamma_p(z) \), generalizes the classical gamma function to multiple variables. It is closely associated with multivariable calculus and has applications in various fields such as statistics, number theory, and mathematical physics.
The theorem of the three geodesics is a result in the field of differential geometry, particularly in the study of geodesics on Riemannian manifolds.
GRB 080913 is a gamma-ray burst (GRB) that was detected on September 13, 2008. Gamma-ray bursts are among the most energetic events in the universe, characterized by the release of a significant amount of gamma radiation over a brief period, typically lasting from milliseconds to several minutes.
GRB 100621A is a gamma-ray burst (GRB) that occurred on June 21, 2010. It was detected by the Swift satellite and is notable for being one of the closest GRBs observed at that time, with a redshift of approximately 0.542, which translates to a distance of about 5.1 billion light-years from Earth.
General equilibrium theory is a branch of economics that studies how supply and demand in multiple markets interact simultaneously and how they achieve an overall equilibrium in an economy. General equilibrium theorists analyze how changes in one part of the economy can affect the entire system, taking into account the interdependencies among different markets.
Hydrargyrum quartz iodide is a chemical compound that can also be referred to by its chemical formula, which typically indicates the presence of mercury (hydrargyrum is the Latin name for mercury), quartz, and iodine. This compound can be related to specific applications in fields such as materials science or photonics, particularly in the development of particular types of optical materials or devices.
A fluorescent lamp is a type of electric light that works by passing an electric current through a gas, which emits ultraviolet light. This ultraviolet light then excites a phosphor coating on the inside of the glass tube, causing it to emit visible light. Fluorescent lamps are commonly used in various applications due to their energy efficiency and longer lifespan compared to traditional incandescent bulbs.
Fluorescent lamps are a type of electric lamp that produces light by the excitation of gas. They work by passing an electric current through a gas (typically argon or neon) which produces ultraviolet (UV) light. This UV light then interacts with a phosphor coating on the inside of the lamp, causing it to emit visible light. Fluorescent lamps are widely used for their energy efficiency and longer lifespans compared to incandescent lamps.
A germicidal lamp is a type of ultraviolet (UV) lamp that emits UV-C light, which has wavelengths typically between 200 and 280 nanometers. This UV-C light is effective at disinfecting surfaces, air, and water by killing or inactivating microorganisms such as bacteria, viruses, and fungi. Germicidal lamps are commonly used in various applications including: 1. **Healthcare Settings**: To sterilize operating rooms, patient rooms, and medical equipment.
The factorial moment generating function (FMGF) is a generating function that is particularly useful in probability and statistics for dealing with discrete random variables, especially those that take non-negative integer values. The FMGF is closely related to the moments of a random variable but is structured in a way that makes it suitable for analyzing distributions where counts or frequencies are relevant, like the Poisson distribution or the negative binomial distribution.
Edible gels are a type of food product made from gelling agents that create a gel-like texture. They are commonly used in the food industry for various applications, including as thickening agents, stabilizers, or for creating desserts and confections. Some common gelling agents used to produce edible gels include: 1. **Gelatin**: A protein derived from animal collagen, used in a variety of sweets like gummy candies, marshmallows, and jellies.
Gelclair is a topical medication typically used to relieve oral mucositis, which is an inflammation and ulceration of the mucous membranes in the mouth. This condition can occur as a side effect of chemotherapy, radiation therapy, or other treatments. Gelclair is formulated as a gel that provides a protective coating over the oral mucosa, helping to soothe pain and discomfort, promote healing, and reduce inflammation.
Hantz reactions, also known as Hantzsch reactions, refer to a series of chemical reactions that involve the synthesis of dihydropyridines. These reactions are named after the German chemist Heinrich Hantzsch, who developed the method. In its most common form, the Hantzsch reaction involves the condensation of aldehydes (or ketones), β-ketoesters (or certain other carbonyl compounds), and ammonia or primary amines in the presence of a reducing agent.

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.
