Susumu Okubo (1916–2001) was a prominent Japanese physicist known for his contributions to the field of particle physics, particularly in the development of the quark model and the understanding of mesons and baryons. He is best remembered for the Okubo mixing, a theoretical concept that describes the mixing of different particle states due to symmetries in particle interactions.

Perfusion CT, or Perfusion Computed Tomography, is an advanced imaging technique used to assess blood flow (perfusion) in various tissues, most commonly in the brain and tumors. It combines standard CT imaging with the use of a contrast agent to visualize blood flow dynamics in real-time.

Sven Koenig is a computer scientist known for his work in artificial intelligence, robotics, and multi-agent systems. He is particularly recognized for his research in areas such as path planning, decision-making, and the development of algorithms that enable autonomous agents to operate effectively in complex environments. His contributions often focus on the interplay between theory and practical applications, including how agents can learn and adapt their strategies based on their interactions with the environment.

"Firearms by designer" typically refers to firearms that are categorized or identified by their design and the individuals or companies that created them. This designation can include a wide range of firearms, such as handguns, rifles, shotguns, and military firearms, each associated with specific designers or manufacturers known for their innovation, craftsmanship, and influence in the firearms industry.

"Musica universalis," or the "music of the spheres," is a philosophical concept that dates back to ancient Greece. It expresses the idea that there is a certain harmony and mathematical order to the cosmos, where celestial bodies—the planets and stars—produce a form of music through their movements and relationships in space. This concept suggests that the universe is governed by harmonies similar to those in music, based on mathematical ratios.

In "Miami Vice," firearms are often depicted as essential elements that contribute to the show's gritty, action-oriented narrative. The series, which aired from 1984 to 1989, is known for its stylish portrayal of the Miami drug trade and the law enforcement efforts to combat it. The characters, particularly the two main protagonists, Sonny Crockett (played by Don Johnson) and Ricardo Tubbs (played by Phillip Michael Thomas), frequently engage in high-stakes confrontations that involve various firearms.

A sympiesometer is a type of barometer that measures atmospheric pressure. The name comes from the combination of Greek words that suggest it operates under the principle of atmospheric pressure changes. The device typically consists of a sealed glass tube filled with a liquid, often mercury or water, which reacts to changes in atmospheric pressure by causing the liquid level to rise or fall.

A symplectic basis is a particular type of basis for a symplectic vector space, which is a vector space equipped with a non-degenerate, skew-symmetric bilinear form known as the symplectic form.

The Polish Enigma double refers to a specific type of cryptographic machine used during World War II, named after its relation to the Enigma machine utilized by the German military. The "Polish Enigma" itself relates to the early work by Polish mathematicians and cryptologists in the 1930s, particularly Marian Rejewski, who played a crucial role in breaking the Enigma cipher.

Symplectic space is a fundamental concept in mathematics, specifically in the field of symplectic geometry, which is a branch of differential geometry and Hamiltonian mechanics. A symplectic space is a smooth, even-dimensional manifold equipped with a closed non-degenerate differential 2-form called the symplectic form.

Firefox extensions are small software programs that add functionality to the Firefox web browser. These extensions, also known as add-ons or plugins, can enhance the browser's capabilities by providing new features, optimizing performance, and customizing the user experience. Here are some key points about Firefox extensions: 1. **Functionality**: Extensions can provide a wide range of functionalities, such as ad-blocking, password management, productivity tools, privacy enhancements, and social media integration.

A computer terminal is an electronic or electromechanical device that is used to input data into a computer and display output from it. Historically, terminals were physical devices that allowed users to interact with a mainframe or minicomputer, typically consisting of a keyboard for input and a monitor for output.

Perfect competition is a theoretical market structure characterized by a set of specific conditions that foster an idealized form of competition among firms. In a perfectly competitive market, the following key assumptions typically hold true: 1. **Many Buyers and Sellers**: There are a large number of buyers and sellers in the market, none of whom has significant market power to influence prices. Each firm is a price taker.

Microsoft PixelSense, originally known as Microsoft Surface (before the name was repurposed for the Surface line of tablets and laptops), is a technology that enables users to interact with digital content through touch and gesture recognition on a large display. Introduced in 2007, PixelSense was designed to create an immersive user experience in which multiple users could interact with the screen simultaneously.

Perfect obstruction theory is a concept in algebraic geometry and moduli theory that provides a way to study the deformation theory of algebraic varieties using perfect complexes. It extends the classical deformation theory by incorporating derived algebraic geometry and coherent sheaves. In more technical terms, perfect obstruction theory provides a framework to systematically track how certain geometric objects (like schemes or varieties) can be "deformed" within a moduli space.

Pamela Samuelson is a prominent legal scholar known for her work in intellectual property law, technology law, and information policy. She is a professor at the University of California, Berkeley, where she has made significant contributions to the understanding of copyright, trademark, and patent law, particularly in the context of digital technology and the internet.

The term "Taiwanese computer scientists" refers to researchers, educators, practitioners, and experts in the field of computer science who are from Taiwan or have Taiwanese nationality. Traditionally, Taiwanese computer scientists have contributed significantly to various areas within computer science, including artificial intelligence, software engineering, computer networks, human-computer interaction, and more.

In crystallography, a periodic graph refers to a visual representation of the repeating patterns that characterize crystal structures. Crystals are solid materials where atoms are arranged in a highly ordered and repeating three-dimensional pattern. This periodic arrangement can be modeled mathematically and graphically, allowing scientists to analyze and understand the properties of materials.

The Tate pairing is a mathematical operation in the realm of algebraic geometry and number theory, specifically on elliptic curves and abelian varieties. It has significant applications in cryptography, particularly in the construction of cryptographic primitives such as identity-based encryption and digital signatures. ### Definition: The Tate pairing is defined on certain types of elliptic curves over finite fields, particularly those that can be described using a Weil pairing.

The Rayleigh number (Ra) is a dimensionless number that characterizes the flow and stability of fluids in a system when buoyancy forces are significant compared to viscous forces. It is particularly important in the study of convection, particularly natural convection, where fluid motion is induced by differences in temperature and thus density.
