A Folkman graph is a specific type of graph in graph theory named after the mathematician Julian Folkman. It is characterized by its properties related to edge connectivity and its structure. One important aspect of Folkman graphs is that they are used to investigate the relationship between graph properties such as colorings and connectivity. Specifically, Folkman graphs can be employed in studies related to hypergraphs and their extensions, especially in the context of coloring problems in combinatorial mathematics.
Forced Rayleigh scattering (FRS) is a technique used to analyze the properties of materials by probing them with light. It is an extension of the classical Rayleigh scattering phenomenon, which refers to the scattering of light by small particles. In classical Rayleigh scattering, the incident light interacts with particles in a medium, leading to scattered light whose characteristics depend on the size, shape, and composition of those particles.
The Titan II GLV (Gemini Launch Vehicle) was a variant of the Titan II rocket specifically designed to support the Gemini space program initiated by NASA in the 1960s. The Titan II rocket itself was a two-stage, intercontinental ballistic missile (ICBM) that was adapted for spaceflight use. The Titan II GLV was modified to serve as an expendable launch vehicle capable of carrying crewed Gemini spacecraft into low Earth orbit.

Special conformal transformations are a specific type of transformation that can be applied in the context of conformal field theories (CFTs) and conformal geometry. In a conformal transformation, angles are preserved, but distances may change. Special conformal transformations are a special subset of these transformations that involve a specific modification of the space-time coordinates.
ADMAR could refer to a few different things, depending on the context. However, one notable reference is to the "Admissions and Discharge Management and Assessment Review" process, which is often implemented in healthcare or educational settings for managing patient admissions and discharges.
Skate sailing is a sport that combines elements of skating and sailing, typically taking place on ice or snow. It involves the use of a specially designed sail and a platform or a sled equipped with skates or skis. Participants propel themselves across frozen bodies of water or snowy landscapes by harnessing the power of the wind with their sails. The sport is similar to land sailing or ice sailing but is distinct in its specific techniques and gear used.
A convex curve is a type of curve in mathematics that has the property that any line segment drawn between two points on the curve lies entirely within or on the curve itself. This means that if you take any two points on the curve and connect them with a straight line, the entire line segment will not cross outside of the curve. Key properties of convex curves include: 1. **Non-Concavity**: A convex curve does not curve inward at any point. Instead, it always bows outward.
Nanotechnology refers to the manipulation of matter on an atomic and molecular scale, typically at dimensions of 1 to 100 nanometers. Its societal impact is significant and multifaceted, encompassing a range of sectors including healthcare, environmental sustainability, energy, electronics, and consumer products. Below are some key aspects of the societal impact of nanotechnology: ### 1.
A calibration curve is a graphical representation that shows the relationship between the measured values of a variable (such as concentration, intensity, etc.) and the corresponding true values for those measurements. It is commonly used in analytical chemistry, biomedical studies, and various fields that require quantitative analysis.
Canada has a complicated history and policy stance regarding weapons of mass destruction (WMD), which generally encompass nuclear, chemical, and biological weapons. Here are some key points regarding Canada's position on these issues: 1. **Nuclear Weapons**: - Canada does not possess nuclear weapons and is a strong advocate for nuclear disarmament.
The Society for Health Systems (SHS) is a professional organization dedicated to improving health systems through the application of engineering and management principles. It is a part of the Institute of Industrial and Systems Engineers (IISE) and focuses on enhancing the quality, efficiency, and effectiveness of healthcare delivery. SHS provides a platform for professionals in the healthcare sector, including engineers, administrators, and researchers, to collaborate, share knowledge, and promote best practices in health systems design and management.
A sodium-vapor lamp is a type of gas discharge lamp that uses sodium vapor to produce light. These lamps are known for their efficiency and distinct yellow-orange color, which is a result of the emission spectrum of sodium. They are commonly used for street lighting and in industrial applications due to their high luminous efficacy and longer lifespan compared to incandescent lamps.
As of my last knowledge update in October 2021, there is no widely known or significant figure by the name of George C. Eltenton. It's possible that he could be a private individual or someone who has gained prominence after that date.
"Specious present" is a philosophical and psychological term that refers to the way humans experience time, particularly how we perceive the present moment. It suggests that our sense of "now" is not just a fleeting instant but rather a stretch of time that can encompass several moments. The concept was notably discussed by philosopher and psychologist William James, who argued that the present is not merely a single point in time but rather a duration that includes the immediate past and immediate future.
The spectral centroid is a measure used in the analysis of sound and music that represents the "center of mass" of a spectrum. In more technical terms, it indicates where the "center" of the mass of the spectrum is located in the frequency domain. It is often considered a descriptor of the brightness or timbre of a sound.
Klee's measure problem is a question in computational geometry, specifically concerning the computation of the volume (or measure) of a union of axis-aligned rectangles in a high-dimensional space. The problem can be succinctly stated as follows: Given a set of \( n \) axis-aligned rectangular boxes in \( d \)-dimensional space, the goal is to compute the measure (or volume) of the union of these rectangles.
Carlos Ibáñez e Ibáñez de Ibero (1808–1893) was a notable Spanish geographer, astronomer, and politician. He is best known for his contributions to the fields of geography and cartography, as well as his involvement in Spanish public life. Ibáñez de Ibero was involved in the scientific community and made significant contributions to the understanding of cartographic principles and the scientific exploration of Spain's territories.

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.
