Fritz Strassmann was a German physicist who is best known for his work in nuclear chemistry and for his role in the discovery of nuclear fission. He was born on February 22, 1902, and passed away on April 22, 1980.
A central angle is an angle whose vertex is at the center of a circle, and whose sides (rays) extend to the circumference of the circle. The central angle is formed between two radii of the circle that connect the center of the circle to two points on its edge. Central angles are important in various mathematical and geometric contexts, particularly in relation to the properties of circles, such as arc length and sector area.
Birkhoff's axioms refer to a set of axioms introduced by mathematician George David Birkhoff in the context of defining the concept of a "relation" in mathematics, particularly pertaining to the fields of algebra and geometry. However, it is important to clarify that Birkhoff is perhaps best known for his work in lattice theory and the foundations of geometry.
As mentioned at Section "Computer security researcher", Ciro Santilli really tends to like people from this area.
Also, the type of programming Ciro used to do, systems programming, is particularly useful to security researchers, e.g. Linux Kernel Module Cheat.

A bicone is a geometric shape that resembles two cones joined at their bases. It resembles a double-cone structure and is commonly found in various contexts, including mathematics, geometry, and design. The shape can be characterized by its symmetrical properties and a specific relationship between its height and the radius of its circular base. In computer graphics and 3D modeling, biconic shapes are often used to represent certain types of objects or to create complex designs.
A bicentric polygon is a type of polygon that possesses both a circumcircle and an incircle. A circumcircle is a circle that passes through all the vertices of the polygon, while an incircle is a circle that is tangent to each side of the polygon. For a polygon to be classified as bicentric, it must meet specific criteria: 1. **Circumcircle**: All the vertices of the polygon lie on a single circle.
Apollonian circles are a fascinating concept in geometry associated with the problem of Apollonius, which involves finding circles that are tangent to three given circles in a plane. The study of these circles reveals insights into various geometric properties, including tangency, curvature, and configuration. In more detail: 1. **Apollonius' Problem**: The classical problem, attributed to Apollonius of Perga, asks for the construction of a circle that is tangent to three given circles.
In mathematics, the term **antiparallel** typically refers to vectors or lines that are oriented in opposite directions. Specifically, two vectors are said to be antiparallel if they have the same magnitude but point in opposite directions. For example, if vector \( \mathbf{a} \) points to the right (e.g.

Many plotting software can be used to create mathematics illustrations. They just tend to have more data-oriented rather than explanatory-oriented output.

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.
