Ferranti Pegasus is a family of computers developed by Ferranti Ltd in the 1960s. It was one of the early commercial computers designed for academic and research institutions. The Pegasus series was known for its use in scientific computing and was notable for its solid-state memory and the ability to handle floating-point arithmetic efficiently. The most recognized model in the series is the Ferranti Pegasus II, which featured improvements in processing power and memory capacity compared to its predecessors.

Fertile materials are substances capable of undergoing fission (splitting of atomic nuclei) to produce energy, as well as being capable of breeding or being converted into fissile materials (materials that can sustain a fission chain reaction). In nuclear physics and engineering, fertile materials can be transformed into fissile materials through neutron absorption and subsequent nuclear reactions.

The Horsehead Nebula, located in the Orion constellation, has inspired various works of fiction across literature, film, and other media. While there isn't a specific singular story titled "Fiction about the Horsehead Nebula," the nebula has served as a striking backdrop and symbol in multiple narratives, often eliciting themes of mystery, the cosmos, and the unknown.

Gödel's incompleteness theorems, formulated by the mathematician Kurt Gödel in the early 20th century, are two fundamental results in mathematical logic and philosophy of mathematics. They reveal inherent limitations in the ability of formal systems to prove all truths about arithmetic.

The Goldschmidt tolerance factor, often denoted as \( t \), is a measure used in mineralogy and materials science to predict the stability of mixed oxide phases, particularly in perovskite structures. It was introduced by the mineralogist Victor Moritz Goldschmidt in the early 20th century. The tolerance factor is defined using the ionic radii of the involved cations and anions in the crystal structure.

Golomb coding is a form of entropy encoding used in data compression, particularly suitable for representing non-negative integers with a geometric probability distribution. It was introduced by Solomon W. Golomb. The primary idea behind Golomb coding is to efficiently encode integers that commonly occur in certain applications, such as run-length encoding or certain types of image compression.

Goodput refers to the measure of useful transmitted data over a network, excluding protocol overhead, retransmissions, and any other non-useful data. Essentially, it represents the actual amount of data that is successfully delivered to the receiver and can be used by the application layer. Goodput is a critical metric for evaluating network performance as it provides a clearer picture of how much useful information is being effectively communicated.

Gorre & Daphetid is a fictional location in the role-playing game "Dungeons & Dragons" (D&D) and is part of the larger campaign setting known as the "World of Greyhawk." It is a unique geographical area characterized by its dark and mysterious atmosphere, often associated with themes of horror and the supernatural. In Gorre & Daphetid, players typically encounter a range of challenges and adventures, including encounters with various monsters, magical phenomena, and opportunities for exploration.

GPSD, or GPS Daemon, is an open-source software program that establishes a service for managing GPS (Global Positioning System) data on a Unix-like operating system. It acts as an interface between GPS devices and applications that need to utilize location information. Key features of GPSD include: 1. **Device Independence**: It abstracts the complexities of interacting with various GPS hardware, allowing multiple applications to access location data from various GPS devices simultaneously without needing to know the specifics of those devices.

GPS drawing, also known as GPS art or GPS mapping, is a creative practice that involves using a GPS device or smartphone to create images, patterns, or designs by moving through physical space. As individuals or groups walk, run, or bike along specific routes, their movements are tracked by GPS technology, which records the coordinates to create a visual representation of the route taken.

The term "Grace Clark" could refer to several different subjects, including a person's name or a character in literature or media. Without additional context, it's difficult to provide a specific answer.

Graduate Texts in Mathematics (GTM) is a series of advanced mathematics textbooks published by Springer. The series is designed primarily for graduate students and advanced undergraduates, covering a wide range of topics in pure and applied mathematics. Each book in the series typically provides thorough treatments of specific subjects, complete with definitions, theorems, proofs, and examples. The books are written by prominent mathematicians and are intended to be both rigorous and accessible to those with a solid background in mathematics.

Graphene plasmonics is a field of study that explores the interaction between graphene— a single layer of carbon atoms arranged in a two-dimensional lattice— and plasmons, which are coherent oscillations of electrons that occur at the surface of conductors and can propagate along metal-dielectric interfaces. ### Key Concepts: 1. **Plasmons**: Plasmons are quasi-particles resulting from the collective oscillations of free electrons in a material.

The Grand Accélérateur National d'Ions Lourds (GANIL) is a national facility for nuclear physics research located in Caen, France. It is primarily dedicated to the study of heavy ions, which are nuclei of heavy elements. GANIL is known for its ability to accelerate these heavy ions to high energies, allowing scientists to explore a variety of nuclear phenomena, including nuclear structure, reactions, and the properties of exotic nuclei.

The graph coloring game is a two-player combinatorial game based on the principles of graph theory. In this game, players take turns coloring the vertices of a graph with the goal of ensuring that no two adjacent vertices share the same color. ### Key Components of the Game 1. **Graph**: The game is played on a finite graph, which consists of a set of vertices (nodes) connected by edges (lines).

Graph distance refers to a measure of distance between nodes (or vertices) in a graph. In graph theory, nodes are the individual entities (like cities, web pages, etc.), and edges are the connections or relationships between these entities. There are a few different interpretations and methodologies for calculating graph distance, depending on the type of graph and the specific context: 1. **Shortest Path Distance**: The most common definition of graph distance is the shortest path distance between two nodes.

Graph rewriting is a formalism used in computer science and mathematical logic to describe the transformation of graphs based on specific rules or patterns. It involves the application of rewrite rules to modify a graph structure, allowing for the generation of new graphs or the simplification of existing ones. Graph rewriting is utilized in various fields, including programming languages, automated reasoning, and modeling complex systems. ### Key Concepts: 1. **Graphs**: A graph is a collection of nodes (vertices) connected by edges.

Grassmann–Cayley algebra is an algebraic structure that extends the concepts of vector spaces and linear algebra, focusing on the interactions of multilinear forms and multilinear transformations. This algebra allows for the representation of geometric and algebraic concepts, combining aspects of Grassmann algebra and Cayley algebra. ### Key Concepts 1. **Grassmann Algebra**: Grassmann algebra, named after Hermann Grassmann, deals with the exterior algebra of a vector space.

Great-circle navigation is a method used in air and sea navigation that follows the shortest path between two points on the surface of a sphere. This path is called a great circle, which is the intersection of the surface of the sphere with a plane that passes through the center of the sphere. In practical terms, when plotted on a flat map, great circles appear as curved lines due to the spherical nature of the Earth.

Greedy number partitioning is an approach to divide a set of numbers into a specified number of subsets (or partitions) such that the sums of the numbers in each subset are as equal as possible. This problem falls under the category of optimization problems and is often encountered in various fields, including computer science, operations research, and resource allocation. ### Key Concepts: 1. **Objective**: The main goal is to minimize the difference between the maximum and minimum sums of the partitions.
