Dixon's factorization method is an algorithm used for integer factorization, which is the process of decomposing a composite number into a product of its prime factors. Developed by Peter W. Dixon in the 1980s, this method is particularly effective for factoring large numbers and is based on the principles of quadratic residues and the use of the properties of modular arithmetic.

"Dodgem" typically refers to a type of amusement ride often found at fairs and amusement parks. Also known as "bumper cars," these electric-powered vehicles allow riders to drive around a small arena and collide with one another, resulting in a fun and chaotic experience. The attraction is popular among both children and adults, as it provides an opportunity for playful bumping and maneuvering in a controlled environment.

In fiction, "dolls" can serve various symbolic and thematic purposes, often representing childhood, innocence, or the uncanny. They can embody the following concepts: 1. **Childhood and Innocence**: Dolls are often associated with childhood, serving as toys that represent play and imagination. In many stories, they symbolize innocence and the simplicity of youth. 2. **Symbol of Control**: Dolls can also represent control or manipulation.

Donald Hill Perkins is a name that does not have widely recognized significance in public records or notable events as of my last update in October 2023. There may be individuals with that name, but they may not be prominent figures in history, politics, entertainment, or other fields.

Donald N. Langenberg was a notable American physicist and academic administrator. He served as the chancellor of the University System of Maryland from 1990 to 1998 and was a prominent figure in the field of higher education. Prior to his role in Maryland, he held various positions in academia, including being the president of the University of Delaware. Langenberg was also known for his work in experimental physics, particularly in condensed matter physics.

In the context of textiles, "doubling" refers to a process in yarn production where two or more yarns are twisted together to create a thicker, stronger, or more textured yarn. This technique can improve the yarn's strength, durability, and overall appearance. Doubling is commonly used in various applications, including knitting and weaving, where a more robust or distinctive fabric is desired.

A droplet-shaped wave typically refers to a type of wave form that resembles the shape of a droplet of water. This term is often used in the context of physics and fluid dynamics to describe surface waves that take on a particular form or profile, which can be observed in various mediums, including water and other fluids.

Duncan Sommerville is a figure from Scottish history, known primarily for his role as a soldier and a member of the 2nd Scotland and North England Brigade during World War I. He is best known for his involvement in the battles of the Western Front and his contributions to the war effort.

Dynamical neuroscience is a subfield of neuroscience that focuses on understanding the complex, dynamic behaviors of neural systems over time. It combines principles from various disciplines, including neuroscience, physics, mathematics, and engineering, to study how biological networks of neurons, synapses, and other components interact and evolve in response to internal and external stimuli.

The Dynamical Theory of Crystal Lattices is a theoretical framework used to understand the behavior of atoms in a crystalline solid, particularly in the context of their vibrations, interactions, and thermal properties. This theory is crucial for explaining various phenomena observed in solids, such as thermal conductivity, heat capacity, and the propagation of sound waves.

Dynamic Mechanical Analysis (DMA) is a technique used to measure the mechanical properties of materials as they undergo deformation under oscillating loads. This analytical method provides critical information on viscoelastic properties—how materials respond to mechanical stress, including both their elastic and viscous behavior.

E is a text editor that was developed in the 1970s, primarily by David J. McNab, at Bell Labs. It is notable for being one of the early screen-oriented text editors designed for use with Unix systems. E is characterized by its simplicity and efficiency, allowing users to edit text files directly in a terminal environment. One of the key features of E is its model of operations, which allows users to navigate and manipulate text efficiently through a combination of keyboard commands.

In classical philosophy and ancient science, particularly within the framework of ancient Greek thought, Earth is one of the four fundamental elements, which also include Water, Air, and Fire. These elements were believed to be the basic building blocks of everything in the universe and were often associated with specific qualities: 1. **Earth**: Associated with stability, solidity, and materiality. It symbolizes the physical aspect of the world, representing the ground, nature, and the environment.

Eduardo Fradkin is a renowned theoretical physicist known for his contributions in the areas of condensed matter physics and quantum field theory. He has worked on topics such as topological phases of matter, quantum computing, and various aspects of quantum gravity. In academia, he is often associated with universities and research institutions where he has published numerous articles and papers.

In mathematics, eccentricity is a measure of how much a conic section deviates from being circular. It is primarily used in the context of conic sections, which include circles, ellipses, parabolas, and hyperbolas. Each type of conic section has a specific eccentricity value: 1. **Circle**: The eccentricity is 0. A circle can be thought of as a special case of an ellipse where the two foci coincide at the center.

Ecogeographic rules, also known as ecogeographical rules, refer to patterns of variation in the characteristics of organisms that are systematically associated with geographical and ecological factors. These rules help explain how environmental gradients, such as temperature, precipitation, altitude, and latitude, influence the distribution, morphology, behavior, and physiology of species.

The "economy of transport" refers to the efficient use of resources in the transportation sector to move people and goods. It encompasses various aspects, including: 1. **Cost Efficiency**: Evaluating the economic costs associated with different modes of transport (e.g., road, rail, air, maritime) and finding the most cost-effective method of transportation for a specific supply chain or passenger journey. This includes fuel efficiency, maintenance costs, infrastructure costs, and labor costs.

Edgar Tillyer (1885–1966) was an American painter, photographer, and educator, best known for his work in the field of art education and for his contributions to the visual arts in the United States. He was particularly recognized for his use of light and color in painting. Tillyer was also involved in photography, capturing numerous landscapes and scenes that reflected his artistic vision.

Edmund Hlawka is an Austrian mathematician known for his work in various fields of mathematics, particularly in analysis and number theory. He has also made contributions to the study of continued fractions and the theory of approximation. Hlawka has authored or co-authored several mathematical papers and has been involved in mathematical education and research.
