Edward Arthur Milne (1896–1950) was a prominent British astrophysicist and mathematician known for his significant contributions to the field of cosmology and astronomy. He played a crucial role in developing the theory of stellar structure and the understanding of the universe's expansion. Milne is particularly recognized for his work on the Milne Universe, a cosmological model that describes a homogeneous and isotropic universe.
Edward Brinton is not a widely known public figure or concept, so it's possible that you're referring to a lesser-known individual or a specific context that I might not have information on. There is, however, a significant Edward Brinton who was an American anatomist and paleontologist, known for his contributions to the field of paleobiology.
Edward C. Stone is an American astrophysicist known primarily for his work in space science and his contributions to the study of the solar system and interstellar space. He played a significant role in several important NASA missions, including the Voyager missions, which provided groundbreaking insights into the outer planets and the heliosphere.
Efficient cake-cutting is a concept from game theory and fair division that deals with the equitable and efficient distribution of resources among multiple parties, often illustrated through the metaphor of dividing a cake. The main objective is to divide the cake (or resource) in such a way that all parties involved feel they have received a fair share, while also maximizing the total value of the resource being divided. ### Key Concepts: 1. **Fairness**: The division should be perceived as fair by all participants.
Ehud Hrushovski is an Israeli mathematician known for his work in model theory, a branch of mathematical logic that deals with the relationships between formal languages and their interpretations or models. Born in 1959, Hrushovski has made significant contributions to various areas in logic and mathematics, including the development of new techniques in model theory, algebraic geometry, and set theory.
Eileen Gonzales could refer to different individuals or topics since it's a common name. Without additional context, it's difficult to provide a specific answer.
Einstein-aether theory is a theoretical framework in physics that attempts to describe the interplay between gravity and a sort of "aether" field, an ancient concept that was originally proposed in the context of electromagnetic theory. In its modern incarnation, Einstein-aether theory modifies the standard theory of general relativity by introducing a dynamical vector field, which represents the aether.
The Einstein Cross, also known as Q2237+030, is a fascinating astronomical phenomenon that exemplifies gravitational lensing. It consists of a distant quasar, which is a bright and active region around a supermassive black hole in a galaxy, and is positioned behind a foreground galaxy. The gravitational field of this foreground galaxy warps spacetime, causing the light from the quasar to be bent around it.
The Einsteinhaus, or Einstein House, is a historic building located in Bern, Switzerland. It is famously known as the residence of the renowned physicist Albert Einstein when he lived in the city from 1903 to 1905. During this time, Einstein developed several significant theories, including the special theory of relativity. The house, which is situated in the Bernese Altstadt (Old Town), has been preserved as a museum that showcases Einstein's life and work.
Ejection charge refers to a small amount of propellant or explosive material used in model rocketry or similar applications to deploy or separate components of a system, such as a parachute or payload, from the main body of a rocket after its ascent. When ignited, the ejection charge produces a burst of gas that creates pressure, pushing out the parachute or other components.
Elastance is a term used primarily in physiology and engineering to describe the ability of a structure to resist deformation when a force is applied. In a biological context, it often refers to the elastic properties of tissues and organs, particularly in the respiratory system. In physiology, elastance is the reciprocal of compliance. Compliance measures the ability of a structure to stretch and expand in response to pressure, while elastance measures the stiffness or resistance to that stretch.
Rainer Weiss is a prominent American physicist known for his contributions to the field of gravitational physics and astrophysics. He is best known as one of the co-founders of the Laser Interferometer Gravitational-Wave Observatory (LIGO), which made groundbreaking discoveries in the detection of gravitational waves. This achievement, announced in 2015, confirmed a key prediction of Albert Einstein's general theory of relativity and opened a new era in astrophysics.
Electoral boundary delimitation is the process of defining or redrawing the boundaries of electoral districts or constituencies in order to ensure fair representation in elections. This process is crucial in systems of representative democracy, where political representatives are elected based on geographical areas. Key aspects of electoral boundary delimitation include: 1. **Purpose**: The primary aim is to ensure that each electoral district has roughly equal populations, allowing for equitable representation.
Electrical Impedance Tomography (EIT) is a non-invasive imaging technique that reconstructs the internal conductivity distribution of a medium, typically biological tissues, based on electrical measurements taken at the surface of the medium. It involves applying a small alternating current through electrodes placed on the surface and measuring the resulting voltage differences to infer the electrical impedance of the internal structure.
Bergman's diamond lemma is a result in the field of universal algebra, named after the mathematician I. N. Bergman. It is a tool used to study certain types of algebraic structures, particularly in the context of modules over a ring and in the theory of algebras. The lemma provides conditions under which certain kinds of "multiplications" can be approximately characterized by simpler forms, often involving a basis of sorts.
An electrohydraulic servo valve is a type of control valve that utilizes electrical signals to control the flow of hydraulic fluid in a hydraulic system. It serves as a critical component in automated systems, particularly in applications that require precise control of force, position, or velocity. ### Key Features: 1. **Functionality**: - The servo valve modulates the hydraulic fluid's flow rate and pressure to control the movement of actuators, such as hydraulic cylinders or motors.
Electromotive force (EMF) refers to the energy provided per unit charge by a source of electrical energy, such as a battery, generator, or solar cell, when it generates electric current. Although it uses the term "force," EMF is not a force in the traditional sense; rather, it represents the potential difference (voltage) generated by a source when no current is flowing.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
