The Israeli Transverse Mercator (ITM) is a map projection system used in Israel for geographic information systems (GIS), mapping, and surveying purposes. It is based on the Transverse Mercator projection, which is commonly used for mapping small areas with high accuracy.
The Jordan Transverse Mercator (JTM) is a specific geographical coordinate system used in Jordan, based on the Transverse Mercator projection. This type of projection is commonly employed for mapping and surveying purposes because it provides a good representation of smaller regions by minimizing distortion in distance, area, shape, and direction. The JTM is particularly useful for local and national mapping in Jordan, allowing for precise positioning and navigation within the country.
The Journal of Geodesy is a scientific journal that focuses on the field of geodesy, which is the science of measuring and understanding the Earth's geometric shape, orientation in space, and gravity field. It publishes research articles, technical notes, and reviews related to various aspects of geodesy, including satellite geodesy, geodetic measurements, Earth observation, geophysical applications, and the study of the Earth's crust and its dynamics.
Petr Vaníček is a Czech mathematician primarily known for his work in various fields, including mathematics and geodesy. However, specific details about a comprehensive list of his works might not be readily available or could vary based on the context of his contributions.
Pseudorange is a term used in satellite-based positioning systems, such as Global Positioning System (GPS), to describe the calculated distance between the satellite and the receiver. It is called "pseudorange" because it is not an exact distance; rather, it is an estimate that accounts for several factors. The pseudorange is determined by measuring the time it takes for a signal to travel from the satellite to the receiver and then multiplying that time by the speed of light.
A rhumb line, or loxodrome, is a path on the surface of a sphere (such as Earth) that crosses all meridians at the same angle. In simpler terms, it's a curved line that maintains a constant compass bearing, allowing a navigator to steer a constant angle relative to true north. Rhumb lines are significant in navigation because they provide a means to plot a course that simplifies travel over long distances.
The Schiehallion experiment, conducted in the late 18th century, was a notable geodetic survey designed to measure the gravitational attraction of a mountain, specifically Schiehallion in Scotland. Initiated by the mathematicians Nevil Maskelyne and his assistant, the experiment aimed to determine Earth's density and provide insights into gravitational measurements.
Space geodesy is a branch of geodesy that uses satellite and space-based technologies to measure and monitor the Earth's shape, orientation, gravity field, and other geophysical phenomena. This field employs various techniques, including: 1. **Very Long Baseline Interferometry (VLBI)**: This method uses radio telescopes to measure the time it takes for signals from distant quasars to reach Earth.
David Francis Barrow typically refers to a notable figure in academia, particularly in the field of mathematics or mathematics education. However, without specific context, it's difficult to determine exactly who or what is being referred to, as there may be multiple individuals with that name or it could refer to a specific project or concept associated with him. If you can provide additional context or specifics about what you're looking for (e.g.
Mac operating systems, commonly referred to as macOS, are the operating systems developed by Apple Inc. specifically for their Macintosh line of computers. The macOS platform provides a graphical user interface, core system functionalities, and a range of integrated applications and tools that enhance the user experience. ### Key Features of macOS: 1. **User Interface**: macOS features a clean and intuitive interface known for its Dock, Menu Bar, and Finder, making it user-friendly.
A transit instrument, also known simply as a transit, is a surveying tool used for measuring angles in the horizontal and vertical planes. It combines features of both a theodolite and a telescope and is commonly used in land surveying, construction, and engineering applications. The main components of a transit instrument include: 1. **Telescope**: Used to sight objects and measure angles. It can be rotated in both horizontal and vertical directions.
A spirit level is a tool used to determine whether a surface is horizontal (level) or vertical (plumb). It typically consists of a sealed tube filled with a liquid, usually colored alcohol or water, and an air bubble. The tube is mounted in a frame, often made of wood or metal. When the spirit level is placed on a surface, the bubble will move within the tube. If the surface is perfectly level, the bubble will center itself between two marked lines on the tube.
Very-long-baseline interferometry (VLBI) is a type of astronomical technique used to achieve high angular resolution imaging of radio sources. It involves the use of multiple radio telescopes located at different geographical locations, often thousands of kilometers apart, which work together to observe the same astronomical object simultaneously.
"British geometers" typically refers to mathematicians or mathematicians from the UK who have made significant contributions to the field of geometry. Geometry is a branch of mathematics that deals with the properties, measurements, and relationships of points, lines, angles, surfaces, and solids. Historically, several British mathematicians have been prominent in the development of geometry.
In the context of module theory, a **cotorsion group** refers to an abelian group (or more generally, a module) where every element is "cotorsion" in a certain sense.
Hyperbolic geometers are mathematicians or researchers who specialize in hyperbolic geometry, which is a non-Euclidean geometry characterized by its unique properties and structures. In hyperbolic geometry, the parallel postulate of Euclidean geometry does not hold. Specifically, through a given point not on a line, there are infinitely many lines that do not intersect the given line, in contrast to Euclidean space, where there is exactly one such line.
Adam Friedrich Zürner (1630-1698) was a notable German mathematician and astronomer. He is particularly recognized for his work in the field of astronomical instruments and cartography, contributing to the understanding of celestial mechanics and the improvement of astronomical observations during the 17th century. Zürner is also known for publishing works that detailed his observations and findings, which were significant for the scientific community of his time.
Alexander Nabutovsky is known as a mathematician, specifically recognized for his work in the fields of topology and geometry. He has contributed to various areas of mathematical research, including the study of low-dimensional topology. His work often involves the examination of properties of manifolds and their relationships in different dimensions.
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.
