In differential geometry, an **affine bundle** is a generalization of the concept of a vector bundle. While a vector bundle provides a way to associate a vector space to each point in a base manifold, an affine bundle allows for a more general structure, specifically associating an affine space to each point of the manifold.

Lambda (λ) is a unit of measurement used in various scientific contexts, but it is most commonly associated with the following: 1. **Wavelength**: In physics, particularly in the context of waves, lambda represents the wavelength of a wave (such as light or sound). The wavelength is the distance between successive peaks (or troughs) of the wave.
Dorothée Normand-Cyrot is a French mathematician known for her contributions to the field of mathematics, particularly in areas related to optimization and operations research.

PROJ is an open-source software library used for performing cartographic projections and coordinate transformations. It is widely used in geographic information systems (GIS), remote sensing, and mapping applications. PROJ provides a powerful framework for converting geographic coordinates (latitude and longitude) to projected coordinates (e.g., UTM, state plane) and vice versa. Originally developed in the 1970s, PROJ has evolved over the years and is now maintained by a community of developers.
"Discoveries" by Gabriella Hodosán is a book that explores themes of self-discovery, adventure, and the human experience. It delves into the nuances of personal growth and the journey individuals undertake to find their place in the world. While specific details about the plot or character development are limited, the work is likely to combine elements of reflection, inspiration, and perhaps even elements of travel or exploration, encouraging readers to engage with their own journeys of discovery.
Wireless locating refers to the use of wireless technologies to determine the location of a device or user. This involves various techniques and methodologies that leverage wireless signals, such as radio waves, to ascertain spatial position, often in real-time. There are several key methods and technologies utilized in wireless locating: 1. **GPS (Global Positioning System)**: A satellite-based navigation system that provides accurate location information anywhere on Earth.
Shadow matching is a perceptual and cognitive task or technique often used in psychology and cognitive science. In this context, it typically refers to activities where individuals must identify or match an object, image, or pattern based on its silhouette or shadow rather than its full visual features.
The 150th meridian west is a line of longitude that is 150 degrees west of the Prime Meridian, which is located at 0 degrees longitude. This meridian runs from the North Pole to the South Pole and divides the Earth into the Eastern and Western Hemispheres.
The 173rd meridian west is a line of longitude located 173 degrees west of the Prime Meridian, which is defined as 0 degrees longitude. This meridian runs from the North Pole to the South Pole and is primarily located in the Pacific Ocean. It passes to the east of the International Date Line, where it is relevant for navigation and timekeeping.
The 33rd meridian west is a line of longitude that is 33 degrees west of the Prime Meridian, which is located at 0 degrees longitude. This meridian runs from the North Pole to the South Pole, passing through various geographic regions.
The 37th meridian west of Washington, D.C., is a line of longitude that runs through North America and other regions of the world. Specifically, it is located 37 degrees west of the Prime Meridian, which is at 0 degrees longitude. In the context of the United States, the 37th meridian west of Washington, D.C., would pass through several states as it travels north and south.
The 69th meridian east is a line of longitude that is 69 degrees east of the Prime Meridian, which is located at 0 degrees longitude. Meridians are imaginary lines that run from the North Pole to the South Pole and are used to measure distances east and west of the Prime Meridian. The 69th meridian east passes through several countries, primarily in South Asia, including parts of India, Nepal, and northern Pakistan.
The 9th meridian east is a line of longitude that is 9 degrees east of the Prime Meridian, which is located at 0 degrees longitude. Meridians run from the North Pole to the South Pole, and the 9th meridian east is one of the lines that helps define geographic coordinates on the Earth. This meridian runs through several countries in Europe and Africa. In Europe, it passes through countries such as Germany, Austria, and Slovenia.
The Third Principal Meridian is a north-south line of longitude that serves as a reference point for land surveying in the United States, specifically in the region west of the Ohio River. Established by the U.S. government in the early 19th century, it is one of several principal meridians used in the Public Land Survey System (PLSS). The Third Principal Meridian runs through an area that includes parts of the states of Illinois, Missouri, and Wisconsin.
Geomatics engineering is a diverse field that focuses on the collection, analysis, and interpretation of geographic data. It integrates various technologies and methodologies related to surveying, mapping, remote sensing, geographic information systems (GIS), and spatial data analysis.

This includes using tools such as total stations, GPS, and laser scanning.
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.
