The Argand system, also known as the Argand plane or complex plane, is a way of representing complex numbers geometrically. Named after the French mathematician Jean-Robert Argand, it allows complex numbers to be visualized and analyzed in a two-dimensional space. In the Argand plane: - The horizontal axis (usually referred to as the x-axis) represents the real part of a complex number.
The term "almost all" typically refers to a large majority of a particular group or set, but not quite all of it. This phrase is often used in contexts such as statistics, surveys, or general discussions to convey that while nearly every member of a group meets a certain criterion or holds a certain opinion, there are still a few exceptions.
Set-builder notation is a mathematical notation used to describe a set by specifying a property that its members must satisfy. It allows for the concise definition of sets, especially those that are infinite or defined by a particular condition.
A vortex (plural: vortices) is a flow pattern characterized by a rotating, swirling motion of fluid (which can be gas or liquid) around an axis. Vortices can occur in many different contexts, including in nature, engineering, and physics. Some key characteristics of vortices include: 1. **Rotation**: The fluid moves in a circular or spiral path around a central core or axis. The speed and direction of rotation can vary.
Apatite is a group of phosphate minerals that are widely found in nature. The general formula for apatite is often represented as Ca5(PO4)3(F,Cl,OH), indicating that it primarily consists of calcium phosphate, with varying amounts of fluorine, chlorine, or hydroxyl ions. It comes in several forms and colors and is an important component of biological systems, particularly in the formation of bones and teeth in vertebrates.
As of 2018-12, I believe that I might have fried the UART on this board when I burnt my last UART to USB converter by connecting ground to 5V.

In the context of design and manufacturing, particularly in industries such as automotive and aerospace, a "Class A surface" refers to a high-quality surface finish that is characterized by its aesthetic appearance and smoothness. These surfaces are typically visible and often have demanding visual requirements. Class A surfaces are essential for parts that are exposed to public view or that have strict aesthetic criteria, such as the outer body panels of vehicles.
Hopi mythology refers to the rich spiritual and cultural beliefs of the Hopi people, a Native American tribe primarily located in northeastern Arizona. Their mythology encompasses a diverse array of stories, legends, and teachings that convey their understanding of the world, creation, and the interconnectedness of all life. Key elements of Hopi mythology include: 1. **Creation Stories**: Hopi mythology speaks of various creation narratives, including the emergence of people from different worlds or realms.
MPIR, which stands for "Multiprecision Integers and Rationals," is a software library designed for performing high-precision arithmetic on integers and rational numbers. It is a fork of the GNU Multiple Precision Arithmetic Library (GMP) and provides similar functionality but with enhancements and optimizations suited for certain applications.
The number 1 is a natural number that follows 0 and precedes 2. It is the first positive integer and has several important properties in mathematics: 1. **Identity Element**: In multiplication, 1 is the multiplicative identity, meaning that any number multiplied by 1 remains unchanged (e.g., \( n \times 1 = n \)).
Libratus is an advanced artificial intelligence program developed by researchers at Carnegie Mellon University, designed to play the game of heads-up no-limit poker. It gained significant attention for its ability to outperform professional human poker players in a series of matches in early 2017. Libratus utilizes a combination of techniques from game theory, machine learning, and computational methods to make decisions during gameplay.
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.
