The Neovius surface refers to a specific type of mathematical surface that has properties useful in the study of differential geometry and topology. It is named after the Finnish mathematician A.F. Neovius, who studied the surface and its properties. The Neovius surface is typically characterized by its complex structure, including features like cusps and self-intersections, making it interesting from the perspectives of both geometry and mathematical physics.

Supergeometry is a branch of mathematics that extends the concepts of geometry to include both geometric structures and "supersymmetrical" objects, which involve odd or "fermionic" dimensions. It arises from the study of supersymmetry in theoretical physics, where it plays a crucial role in string theory and quantum field theory. In conventional geometry, one typically works with spaces that are defined by traditional notions of points and curves in even-dimensional Euclidean spaces.

Synthetic Differential Geometry (SDG) is a branch of mathematics that provides a framework for differential geometry using a synthetic or categorical approach, rather than relying on traditional set-theoretic and analytical foundations. This approach is particularly notable for its use of "infinitesimals," which are small quantities that can be treated algebraically in a way that is similar to how they are used in non-standard analysis.

The term "tangential angle" can refer to different concepts depending on the context, but it generally relates to the angle formed by a tangent line to a curve or surface. Here are a couple of specific interpretations: 1. **In Geometry**: The tangential angle can refer to the angle between a tangent line (a line that just touches a curve at a single point) and the horizontal axis (or another reference line).

The Disc theorem is a concept in complex analysis and deals with the behavior of holomorphic functions. Specifically, it is related to the area of function theory. While there are various formulations and different contexts in which the term "Disc theorem" might be used, one specific interpretation often referenced involves properties related to holomorphic functions defined on the unit disk in the complex plane.

The Generalized Stokes' Theorem is a fundamental result in differential geometry and vector calculus that extends the classical Stokes' theorem, relating integrals of differential forms over manifolds to their behavior on the boundaries of those manifolds. It serves as a powerful tool in various fields such as physics, engineering, and mathematics, particularly in the study of differential forms, topology, and manifold theory.

The Kervaire invariant is a concept in algebraic topology, specifically in the study of bordism theory and the classification of high-dimensional manifolds. It is named after the mathematician Michel Kervaire, who introduced it in the context of differentiable manifolds. More formally, the Kervaire invariant is a specific invariant associated with a smooth manifold, particularly focusing on the topology of the manifold's tangent bundle.

Sphere eversion is a process in topology, a branch of mathematics, where a sphere is turned inside out in a continuous manner without creating any creases or tears. The concept involves smoothly deforming a spherical surface so that its inside becomes its outside.

In the context of differential geometry and complex analysis, a **complex geodesic** typically refers to a generalization of the concept of a geodesic in the realm of complex manifolds or complex spaces. The classical notion of a geodesic is a curve that is locally a distance minimizer between points in a given space. In Riemannian geometry, geodesics are trajectories that exhibit extremal properties (typically, minimizing lengths) in a curved space.

Static spacetime is a concept in general relativity that refers to a type of spacetime geometry that is both time-independent (static) and has a specific symmetry. More formally, a static spacetime is one where the gravitational field does not change over time and exhibits certain symmetries, particularly time translation symmetry and spatial symmetry. Key characteristics of static spacetimes include: 1. **Time Independence**: The metric tensor, which describes the geometry of spacetime, does not vary with time.

Serge Rudaz is a philosopher, filmmaker, and writer known for his contributions to discussions on philosophy, ethics, and the intersection of these fields with cinematic narratives. His work often explores the impact of media on societal values and individual perception.

As of my last knowledge update in October 2021, Thomas Timusk is a prominent physicist known for his contributions to the field of condensed matter physics. He has worked on topics such as superconductivity, magnetism, and other critical phenomena in materials. His research has often focused on the use of experimental techniques to study the properties of materials at low temperatures.

W. G. Unruh is a prominent theoretical physicist known for his work in several areas of physics, including general relativity, quantum field theory, and cosmology. One of his most significant contributions is the formulation of what is now known as the Unruh effect. This phenomenon predicts that an observer accelerating through a vacuum will observe thermal radiation (akin to blackbody radiation), even though an inertial observer in that same vacuum would perceive it as empty space.

Russell W. Porter was an American astronomer and a significant figure in the field of optics and telescope design, particularly known for his pioneering work in amateur astronomy. He is best known for his contributions to the design and construction of high-quality telescopes, particularly the "Porter Garden Telescope," which served as a model for many amateur telescopes in the 20th century.

Vladilen Minin is not a widely recognized figure, concept, or term within the public domain as of my last knowledge update in October 2023. It's possible that he could be a private individual, a local figure, or a recent development that hasn’t gained broad recognition.

Vladimir Shiltsev is a prominent physicist and researcher known for his work in the field of particle physics, particularly in relation to accelerator science and technology. He has been involved with major projects, including work at Fermilab, where he has contributed to the development and improvement of particle accelerators and experiments in high-energy physics. Shiltsev's contributions often focus on challenges in the fields of beam dynamics, accelerator design, and applications of particle accelerators in various scientific disciplines.

Yuri Osipyan is a name that may not widely refer to a specific well-known individual or concept in popular culture or academia up until my last update in October 2023. It’s possible that he may be a less publicized figure, a private individual, or someone who has gained attention more recently.

Neil Turok is a South African theoretical physicist known for his work in cosmology and theoretical physics. He is particularly recognized for his contributions to understanding the early universe and the nature of the Big Bang. Turok has been involved in research related to the cyclic universe model, which proposes that the universe undergoes endless cycles of expansion and contraction. He has also done significant work in mathematical physics and has been an advocate for scientific education in Africa.
