Computational topology is a branch of mathematics and computer science that focuses on the study of topological properties and structures through computational methods. It combines techniques from topology, a field concerned with the properties of space that are preserved under continuous transformations, with algorithms and data structures to analyze and manipulate topological spaces.
Geodesy is the scientific discipline that deals with the measurement and representation of the Earth’s shape, orientation in space, and gravitational field, as well as their variations over time. It encompasses various aspects such as: 1. **Earth Measurement**: Determining the size and shape of the Earth, which is not a perfect sphere but rather an oblate spheroid due to its rotation.
"Palestinian physicists" refers to individuals from Palestine who specialize in the field of physics. They may work in various subfields such as theoretical physics, experimental physics, condensed matter physics, astrophysics, or particle physics, among others. The community of Palestinian physicists may include those working in universities, research institutions, and other scientific organizations, both within the Palestinian territories and abroad.
The term "Sudanese physicists" typically refers to individuals from Sudan who work or specialize in the field of physics. Sudan has a history of contributing to various fields of science, including physics, through its universities and research institutions. Sudanese physicists may engage in a wide range of areas within physics, such as theoretical physics, experimental physics, astrophysics, and applied physics, among others.
Binary arithmetic is a type of arithmetic that operates on binary numbers, which are numbers expressed in the base-2 numeral system. In binary, only two digits are used, 0 and 1, as opposed to the decimal system, which uses ten digits (0-9). ### Basic Binary Operations There are several fundamental operations in binary arithmetic similar to decimal arithmetic, including: 1. **Addition**: - The rules for binary addition are similar to those for decimal addition.
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.

- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
