The dot product is a positive definite matrix, and so we see that those will have an important link to familiar geometry.

GeoGebra is a dynamic mathematics software that combines geometry, algebra, statistics, calculus, and other areas of mathematics into an interactive environment. It is widely used by students, educators, and researchers to visualize and explore mathematical concepts. Key features of GeoGebra include: 1. **Interactive Geometry**: Users can create and manipulate geometric constructions, which helps in understanding geometric properties and relationships.

Egyptian mathematicians refer to the mathematicians from ancient Egypt who made significant contributions to mathematics, particularly from around 3000 BCE to 300 CE. The ancient Egyptians developed a practical approach to mathematics that was closely tied to their needs in agriculture, trade, and engineering, especially in the construction of monumental architecture such as pyramids and temples.

Electrical breakdown refers to the phenomenon that occurs when an insulating material becomes conductive due to the application of a sufficient electric field. When the electric field strength exceeds a critical threshold, electrons are stripped from their atoms within the insulating material, leading to a sudden increase in conductivity and the formation of a plasma or a conducting path through the material. This can result in an uncontrolled flow of electricity, often leading to catastrophic failure of electrical devices, arcing, or damage to the insulating material.

Link-Systems International (LSI) is an organization specializing in providing educational resources and services, particularly in the realm of online learning and technology-enhanced education. Founded to address the growing need for innovative educational solutions, LSI offers a range of products and services that often include online tutoring platforms, learning management systems, and tools aimed at improving student engagement and academic success.

As of my last knowledge update in October 2021, "Matheass" does not appear to be a widely recognized term, entity, or concept in mathematics, science, or popular culture. It's possible it could refer to a new concept, product, or specific niche community that has developed or gained popularity since then.

When we have a symmetric matrix, a change of basis keeps symmetry iff it is done by an orthogonal matrix, in which case:

Maths Pathway is an educational program designed to enhance mathematics learning in primary and secondary school contexts. It focuses on personalized learning pathways for students, enabling them to engage with mathematical concepts at their own pace and level. The program typically employs a combination of adaptive learning technologies, curriculum resources, and teacher support to tailor the learning experience to individual student needs.

TODO how close does it get to Shannon's limit?

Mathspace is an educational platform designed to help students learn and practice mathematics through an interactive and adaptive online environment. The platform typically includes features such as step-by-step problem-solving, personalized learning paths, and real-time feedback, allowing students to work at their own pace and receive guidance as they tackle various math concepts. Mathspace aims to make math more engaging and accessible, often integrating multimedia resources, interactive exercises, and assessments.

Every vector space is defined over a field.

E.g. in ${\mathbb{R}}^3$, the underlying field is $\mathbb{R}$, the real numbers. And in ${\mathbb{C}}^2$ the underlying field is $\mathbb{C}$, the complex numbers.

Any field can be used, including finite field. But the underlying thing has to be a field, because the definitions of a vector need all field properties to hold to make sense.

Elements of the underlying field of a vector space are known as scalar.

A member of the underlying field of a vector space. E.g. in ${\mathbb{R}}^3$, the underlying field is $\mathbb{R}$, and a scalar is a member of $\mathbb{R}$, i.e. a real number.

Matita is a digital tool designed for various educational purposes, primarily focusing on interactive learning experiences. It allows educators to create content that can be used in classrooms, enhancing student engagement through tools like interactive exercises, quizzes, and multimedia resources. Matita often emphasizes usability and accessibility, catering to diverse learning styles.
