Orthometric height is the height of a point on the Earth's surface above the geoid, which is an equipotential surface that represents mean sea level. In simpler terms, it is the vertical distance from a point on the Earth's surface to the geoid. Orthometric heights are important in various fields such as geodesy, surveying, and engineering, as they provide a more accurate representation of height that takes into account the gravitational variations across the Earth's surface.
Eduard Zehnder is known as a distinguished Swiss physicist, particularly recognized for his contributions to the field of quantum optics. He is notable for his research on quantum measurement, coherent states of light, and various aspects of laser physics. Zehnder is also associated with the development of the Zehnder interferometer, a device used to demonstrate the wave-particle duality of light and measure various physical properties through interference patterns.
Dieter Jungnickel is a notable figure in the field of mathematics, particularly known for his contributions to combinatorial designs and graph theory. He has authored several works on these topics and is recognized for his expertise and research in these areas.
A list of geometers typically refers to notable mathematicians and scientists who have made significant contributions to the field of geometry. Here are some of the most prominent figures in the history of geometry: 1. **Euclid (c. 300 BC)** - Often referred to as the "father of geometry," he is best known for his work *Elements*, which systematically organized much of the knowledge of geometry of his time. 2. **Archimedes (c.
The concept of a graph minor is a fundamental notion in graph theory, particularly in the study of graph structure and graph algorithms. A graph \( H \) is said to be a **minor** of another graph \( G \) if \( H \) can be formed from \( G \) by performing a series of operations that includes: 1. **Edge Deletion**: Removing edges from the graph. 2. **Vertex Deletion**: Removing vertices and incident edges from the graph.
As of my last knowledge update in October 2023, "Fusion Frame" could refer to different concepts depending on the context. Here are two potential interpretations: 1. **Fusion Frame in Technology**: It might refer to a framework or platform that integrates various functionalities or technologies, allowing for seamless interaction and collaboration. For example, in software development, a "fusion" framework could combine different programming paradigms or technologies, such as integrating front-end frameworks with back-end services.
A quaternionic matrix is a type of matrix whose entries are quaternions, which are an extension of complex numbers.
The term "Saturn-crossing minor planets" refers to a subset of minor planets (asteroids and other small bodies) that have orbits that cross the orbit of Saturn. These objects can belong to different groups, including asteroids from the main asteroid belt as well as centaurs and trans-Neptunian objects. The significance of these objects lies in their potential to cross the orbits of outer planets, which can affect their trajectories due to gravitational interactions.
The Vienna Circle was a group of philosophers and scientists active in Vienna, Austria, during the early 20th century, particularly in the 1920s and 1930s. The group is best known for its role in the development of logical positivism, a philosophical movement that emphasized the importance of empirical verification and scientific methodology.
The first stellation of the rhombic dodecahedron refers to a process of creating a new polyhedron by extending the faces of the original rhombic dodecahedron until they meet. The rhombic dodecahedron is a convex polyhedron with 12 rhombic faces, which is the dual of the cuboctahedron.
An euthanasia device is a tool or contraption designed to assist in administering euthanasia, which is the act of intentionally ending a person's life to relieve them of suffering, often in cases of terminal illness or severe pain. Such devices are intended to provide a humane and painless method for individuals who have chosen to end their life, usually in jurisdictions where euthanasia or assisted suicide is legally permitted.
An electric machine is a device that converts electrical energy into mechanical energy, or vice versa, or sometimes both. These machines can be broadly classified into two categories: electric motors and electric generators. 1. **Electric Motors**: These devices convert electrical energy into mechanical energy. They operate on the principle of electromagnetism, where electric current flowing through coils produces magnetic fields that interact with permanent magnets or other magnetic fields to produce motion.
"Machine sex" typically refers to the interaction between humans and machines in a sexual context. This can encompass various forms of sexual activities involving technology, such as: 1. **Sex Robots**: These are robotic devices designed to simulate human sexual partners. They can range from basic models to highly advanced robots with realistic features and interactive capabilities.
A Self-Propelled Modular Transporter (SPMT) is a type of heavy-duty transport vehicle used for moving oversized loads and heavy equipment. These vehicles are specifically designed to transport large and heavy objects, such as industrial machinery, bridges, and entire buildings, often over short distances, such as from a manufacturing facility to a construction site.
Ceramic engineering is a branch of engineering that focuses on the design, development, and production of ceramic materials, which are inorganic, non-metallic materials that are typically made from oxides, carbides, nitrides, and other compounds. These materials can exhibit a wide range of properties, including high strength, hardness, thermal stability, electrical and thermal insulation, and resistance to chemical corrosion.
Cyclic stress refers to the repeated application of stress on a material over time, which can lead to fatigue and eventual failure. It is typically characterized by cycles of loading and unloading, where the stress varies between a minimum and a maximum value. Cyclic stress is important in materials and structural engineering because many components are subject to fluctuating forces during their service life, such as those in rotating machinery, bridges, and aircraft.
"Engineered cellular magmatic" isn't a widely recognized term in geology or materials science as of my last knowledge update in October 2021. It's possible that the term refers to a new or specialized field of study or a specific research project involving the engineering or manipulation of cellular structures (such as in biological or synthetic contexts) in conjunction with magmatic processes (relating to magma or molten rock).
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
