George G. Shor is a theoretical physicist and mathematician best known for his contributions to quantum computing, particularly his development of Shor's algorithm. This groundbreaking algorithm, introduced in 1994, is designed for factoring large integers efficiently, demonstrating that quantum computers could solve certain problems much faster than classical computers. Shor's algorithm has significant implications for cryptography, particularly in breaking widely-used encryption methods, such as RSA, which relies on the difficulty of factoring large numbers as a security measure.

Calcium channels are specialized membrane proteins that facilitate the movement of calcium ions (Ca²⁺) across cell membranes. They play a crucial role in a variety of physiological processes in both excitable and non-excitable cells. Here are some key aspects of calcium channels: ### Types of Calcium Channels 1. **Voltage-Gated Calcium Channels (VGCCs)**: These channels open in response to changes in membrane potential, allowing Ca²⁺ to flow into the cell.

Calculation is the process of using mathematical operations to determine a value or solve a problem. It involves manipulating numbers or variables according to specific rules and operations, such as addition, subtraction, multiplication, and division, as well as more complex functions and formulas. Calculations can range from simple arithmetic, like adding two numbers, to complex procedures in fields like algebra, calculus, statistics, and engineering.

"Calculus Made Easy" is a popular book written by Silvanus P. Thompson and first published in 1910. The book is known for its accessible and engaging approach to introducing the concepts of calculus to beginners. Thompson aimed to demystify calculus by breaking down complex ideas into simpler terms and using practical examples to illustrate the principles. The book covers fundamental concepts in calculus, including limits, differentiation, integration, and applications of these concepts.

The Calderón–Zygmund lemma is a fundamental result in the theory of singular integrals and is often used in various areas of analysis, including harmonic analysis and partial differential equations. It is named after the mathematicians Alberto Calderón and Anton Zygmund, who made significant contributions to the field.

Orbital overlap refers to the phenomenon that occurs when atomic orbitals from two adjacent atoms come close enough to each other that their electron clouds can interact. This overlap is crucial for the formation of chemical bonds, such as covalent bonds, in which electrons are shared between atoms. In covalent bonding, the greater the overlap of the atomic orbitals, the stronger the bond that is formed.

Calvin Gotlieb is recognized as a prominent figure in the field of computer science, particularly in Canada. He is known for his contributions to computer science education and research, especially in areas such as software engineering and information systems. Gotlieb has been involved in various academic and professional activities, including teaching, mentoring, and developing computer science curricula. He is often associated with the advancement of computer science as a discipline and has contributed to the development of computing-related programs and research initiatives.

A camera, hand lens, and microscope probe are tools used for different purposes in photography, magnification, and analysis at varying levels of detail. ### Camera A camera is a device used to capture images, either as still photographs or as moving images (video). Cameras can vary widely in complexity and capability, ranging from simple point-and-shoot models to advanced DSLRs and mirrorless cameras with interchangeable lenses and extensive manual controls.

The Walsh matrix is a specific type of orthogonal matrix that plays an important role in various areas of mathematics, signal processing, and communications. It is named after the mathematician Joseph Walsh.

Canadian Environmental Sustainability Indicators (CESI) are a set of statistical measures developed by the Government of Canada to track the environmental sustainability of the country's natural resources and ecosystems. The indicators aim to provide data and information that help assess the state of Canada's environment, monitor changes over time, and inform policymakers, stakeholders, and the public about environmental issues. CESI covers various themes, including: 1. **Air Quality**: Indicators related to air pollution levels, sources of emissions, and trends over time.

Canadian materials scientists are researchers, engineers, and professionals based in Canada who specialize in the study, development, and application of materials, including metals, polymers, ceramics, composites, and nanomaterials. They apply principles from physics, chemistry, and engineering to understand the properties and behaviors of materials at the atomic or molecular level.

The Protein-Fragment Complementation Assay (PCA) is a powerful experimental technique used to study protein-protein interactions in living cells. The method is based on the principle that two non-functional fragments of a protein can reconstitute a functional protein when brought into close proximity, which often occurs when two proteins interact.

Canonical coordinates are a set of coordinates used in physics and mathematics, particularly in the context of Hamiltonian mechanics, a reformulation of classical mechanics. They provide a framework for describing the state of a dynamical system in a way that facilitates the analysis of its evolution over time.

Computer draughts players, or checkers programs, are software applications that can play the game of draughts (also known as checkers). These programs use algorithms and artificial intelligence techniques to analyze the game board, evaluate possible moves, and decide on the best course of action. There are various types of computer draughts players, ranging from simple rule-based systems to advanced AI that employs machine learning techniques.

An afocal system refers to an optical configuration in which light rays do not converge or diverge — they exit the system in parallel rays, meaning that the system effectively has no focal point. This type of system is characterized by its ability to take in parallel rays of light and produce output rays that are also parallel.

Battle Management Language (BML) is a standardized language designed for the exchange of information related to military operations and command and control. It was developed to facilitate communication between different military systems and platforms, ensuring that commands and operational information can be shared accurately and efficiently among various command levels and units. BML provides a formalized way to encode and express military concepts, such as unit movements, engagements, and other operational tasks, in a manner that can be interpreted by both humans and software systems.

The BBC Micro expansion unit, often referred to as the BBC Microcomputer System expansion unit or simply an expansion unit, was a peripheral designed to enhance the functionality of the BBC Microcomputer series, which was introduced by Acorn Computers in the early 1980s. The BBC Micro was widely used in schools and homes in the UK and was notable for its educational emphasis and capability.

The Baum–Connes conjecture is a significant proposal in the field of noncommutative geometry and topology, specifically relating to the theory of groups and operator algebras. Formulated by mathematicians Paul Baum and Alain Connes in the 1980s, the conjecture addresses the relationship between the K-theory of certain spaces and the geometry of the groups acting on those spaces.
