"Still Unforgettable" is an album by the legendary singer Nat King Cole, released in 2008. This posthumous album features new arrangements and recordings made with his original vocals from the 1960s, remixed and produced in contemporary styles. The project was created using advanced technology to merge Cole's timeless voice with modern musical elements. The album celebrates his legacy and contributions to music, featuring classic hits alongside lesser-known tracks.

Gauge theory gravity is a theoretical framework that seeks to describe gravity in terms of gauge theories, which are a class of field theories where symmetries play a crucial role. In conventional general relativity, gravity is described as a geometric property of spacetime, expressed through the curvature of the spacetime manifold. In contrast, gauge theories are typically formulated using fields that are invariant under certain transformations (gauge transformations).

Plane-based Geometric Algebra is a specialized framework within the broader field of Geometric Algebra (GA) that focuses on vector spaces defined by planes. Geometric Algebra itself is an algebraic system that extends linear algebra and provides a unified way to handle geometric transformations, including rotations and reflections, as well as more complex geometrical relations. In Plane-based Geometric Algebra, the primary elements are typically oriented around two-dimensional planes, allowing for relevant operations defined in that context.

In mathematics, particularly in the field of group theory, a **discrete group** is a type of group that is equipped with the discrete topology. To understand this concept, let's break it down: 1. **Group**: A group is a set \( G \) along with an operation \( \cdot \) (often just denoted by juxtaposition) that satisfies four fundamental properties: closure, associativity, identity, and the existence of inverses.

"Robots by year" could refer to various topics related to the development and introduction of robots throughout history. Here’s a brief timeline highlighting significant milestones in robotics from the early 20th century to the present: ### 1920s - 1940s - **1921**: Karel Čapek coins the term "robot" in his play "R.U.R." (Rossum's Universal Robots).

Tablet computers have evolved significantly over the years, with several key milestones marking their introduction. Below is a timeline highlighting some notable tablets and their years of introduction: ### 2000s - **2000**: Microsoft introduced the **Windows Tablet PC**, a convertible PC that could be used as a tablet. - **2002**: **Hewlett-Packard** released the **HP Compaq Tablet PC**.

The 1840s marked a significant period in the conceptual development of computing, although practical computers as we know them today did not yet exist. Key events and figures from this time laid the groundwork for future advancements in computer science: 1. **Charles Babbage**: Often referred to as the "father of the computer," Babbage designed the Analytical Engine in the 1830s and continued to work on it into the 1840s.

The 1880s was a significant decade in the history of computing, even though actual computers as we understand them today did not exist at that time. Instead, the era was marked by important developments in early computation and mechanical devices that laid the groundwork for future computer technology.

In 2021, several significant trends and advancements in the field of computer science and technology emerged. Here are some key areas that characterized computer-related introductions during that year: 1. **Artificial Intelligence (AI) and Machine Learning (ML)**: - AI and ML continued to grow, with more applications in various industries, including healthcare, finance, and automation.

The Gödel Prize is an award given for outstanding achievements in the field of theoretical computer science, particularly in the areas related to algorithms, computational complexity, and formal methods. It is named after the mathematician and logician Kurt Gödel, known for his significant contributions to logic and mathematics, particularly his incompleteness theorems. The prize is awarded annually by the Association for Computing Machinery (ACM) and the European Association for Theoretical Computer Science (EATCS).

Alan Perlis (1922–1990) was an influential American computer scientist known for his pioneering work in the field of programming languages and computer science education. He is best known for his contributions to the development of the programming language Lisp and for his work in the areas of compiler design, algorithm theory, and artificial intelligence. Perlis was a strong advocate for the importance of programming as a discipline and emphasized the value of teaching computer science as a foundational skill.

Ataraxia is a term derived from ancient Greek philosophy that refers to a state of serene calmness, peace of mind, and emotional tranquility. It describes an absence of mental disturbance or anxiety, leading to a feeling of inner peace. The concept was particularly significant in the philosophies of the Epicureans and the Stoics, who regarded it as an ideal state to achieve for a fulfilling life.

"De rerum natura," which translates to "On the Nature of Things," is a philosophical poem written by the ancient Roman poet and philosopher Lucretius in the 1st century BCE. It is one of the most significant works of Epicurean philosophy and offers an exploration of nature, the universe, and human existence.

"Dogma" can refer to several different concepts depending on the context. Here are a few common interpretations: 1. **Religious Dogma**: In a religious context, dogma refers to established beliefs or doctrines that are held by a religious group as being authoritative and not subject to dispute. These beliefs are often derived from sacred texts and are considered fundamental to the faith.

The University of Pennsylvania's Department of Mathematics is part of the School of Arts and Sciences and is known for its strong emphasis on both pure and applied mathematics.
