"Gaoyong Zhang" appears to refer to an individual's name rather than a specific concept or widely recognized entity. There might be various individuals with that name in different fields such as academia, technology, or other professions. If you are looking for information about a specific Gaoyong Zhang (e.g.
Jakob Steiner, born in 1796 and dying in 1863, was a Swiss mathematician known for his contributions to geometry, particularly in the field of synthetic geometry. He is often recognized for his work in projective geometry and for introducing certain methods and concepts that are foundational in the study of curves and surfaces. Steiner is best known for Steiner conics, which relate to the properties of conic sections, and for his work on geometric constructions that utilize only straightedge and compass.
Olry Terquem is a notable figure in the field of mathematics, particularly known for his contributions to the theory of numbers and mathematical logic in the 19th century. He was a French mathematician born in 1810 and passed away in 1895. Terquem is recognized for his work on prime numbers and his investigations into mathematical properties and sequences. His research has remnants in academic discussions related to number theory and the foundations of mathematics.
Tom Hull is a mathematician known for his work in the field of mathematics and education. He is particularly recognized for his contributions to the study of mathematical patterns, geometry, and recreational mathematics. Hull has also been involved in developing materials for mathematical education and promoting mathematical problem-solving skills. He is perhaps best known in the context of his work with origami and the mathematical principles that govern the art of paper folding.

Sumner Byron Myers is a name associated with multiple individuals, but it is most commonly recognized in the context of an American mathematician known for his work in mathematical logic and computational theory.
The camera matrix is a fundamental concept in computer vision and graphics, specifically in the context of camera modeling and image formation. It is a mathematical representation that describes the intrinsic and extrinsic parameters of a camera. ### Components of the Camera Matrix 1. **Intrinsic Parameters**: These parameters relate to the internal characteristics of the camera. They include: - **Focal Length (fx, fy)**: Determines the scale of the image and is usually expressed in pixel units.
A border barrier is a physical structure, such as a wall or fence, that is built along a national border to control the movement of people, animals, and goods between countries. These barriers are often constructed with the intention of enhancing national security, preventing illegal immigration, and reducing smuggling or trafficking activities. Border barriers can vary in design, materials, and height, depending on the geographic and political context.
The Essential matrix is a key concept in computer vision and 3D geometry, specifically in the context of stereo vision and structure from motion. It encodes the intrinsic geometry between two views of a scene captured by calibrated cameras. The Essential matrix relates corresponding points in two images taken from different viewpoints and is used to facilitate the recovery of the 3D structure of the scene and the relative poses (rotation and translation) of the cameras.
In computer vision, homography refers to a transformation that relates two planar surfaces in space, allowing one to map points from one image (or perspective) to another. More specifically, it describes the relationship between the coordinates of points in two images when those images are taken from different viewpoints or perspectives of the same planar surface.
The great icosahedral 120-cell (also known as the great icosahedron or the 120-cell) is a four-dimensional polytope, belonging to the family of regular polytopes. It is one of the six convex regular 4-polytopes known as the "4D polytopes," and it is specifically classified as a regular 120-cell.
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.
