The Third Principal Meridian runs through an area that includes parts of the states of Illinois, Missouri, and Wisconsin.
"Esterling" could refer to a few different things depending on the context. Here are a couple of possibilities: 1. **Esterling (Name)**: It may refer to a surname or a given name. 2. **Esterling (Fictional Reference)**: It could be a fictional character, place, or concept in literature, games, or other media.
Earth's crustal evolution refers to the processes and changes that have shaped the Earth's crust from its formation over 4 billion years ago to the present day. This evolution involves a combination of geological, chemical, and physical processes, leading to the development of the distinct layers of the Earth and the diverse geological features we observe today. Here are key aspects of Earth's crustal evolution: 1. **Formation**: The Earth's crust began to form shortly after the planet itself formed around 4.
Ridge push is a geological process that occurs at tectonic plate boundaries, specifically at mid-ocean ridges where new oceanic crust is formed. It is one of the forces that contribute to plate tectonics and the movement of the Earth's lithospheric plates. The process works as follows: 1. **Formation of New Crust**: At mid-ocean ridges, magma rises from the mantle to create new oceanic crust as tectonic plates pull apart.
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. Here are some key components of geomatics engineering: 1. **Surveying**: Geomatics engineers perform land surveys to determine the precise positions of points on the Earth's surface. This includes using tools such as total stations, GPS, and laser scanning.
Triangulation is a method used in various fields, including mathematics, surveying, navigation, social sciences, and qualitative research, to determine the location or characteristics of a point or phenomenon by utilizing the properties of triangles.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
