Mabel Minerva Young appears to be a name that may not have widely known or prominent references in public data or literature up to October 2023. It's possible she is a historical figure, a character in a piece of literature, or someone who may not have gained significant public attention.

Mario Pieri is a significant figure in the field of mathematics, particularly known for his contributions to the area of geometry and topology. His work includes the study of algebraic curves, surfaces, and other geometric entities. Pieri's contributions are notable in the context of Italian mathematics in the early 20th century, and he is perhaps most famous for Pieri's theorem, which relates to the intersection of algebraic surfaces.

Elmer Rees may refer to different individuals or contexts. However, one notable Elmer Rees is a prominent figure in the world of education. He was an influential educator and administrator known for his work in various educational institutions.

Moritz Pasch (1843–1930) was a German mathematician known primarily for his contributions to the foundations of geometry and for advancing the study of projective geometry. He is recognized for developing the concept of projective coordinates and making significant strides in the logical foundations of mathematics. Pasch's work focused on the importance of rigor in geometry, emphasizing the necessity of clear definitions and logical deductions.

Nikolai Ivanov is a Russian mathematician known for his contributions to various fields within mathematics, particularly in topology and algebraic topology. He has made significant advances in the study of manifolds, homotopy theory, and the topology of higher-dimensional spaces. Ivanov has also been involved in research related to geometric group theory and the study of symplectic structures.

A Hall plane is a concept used in crystallography and solid-state physics to describe specific orientations within a crystal lattice. The term is often associated with "Hall groups" or the "Hall notation," which classify different types of plane symmetries and orientations in crystals. In crystallography, planes within a crystal are defined by Miller indices, which are a set of three integers that describe the orientation of the plane in relation to the axes of the crystal lattice.

In manufacturing, "flatness" refers to the condition of a surface being perfectly flat, which means it should not have any deviations from a true geometric plane. This characteristic is crucial for various applications, especially in industries such as machining, fabrication, and assembly, where precise tolerances are required. ### Importance of Flatness in Manufacturing: 1. **Precision Assembly**: Flat surfaces are essential for ensuring that components fit together correctly.

"The Confusion" is the title of a historical novel by Neal Stephenson, published in 2004. It is the second book in "The Baroque Cycle," which is a series that blends history, science, and adventure in the early modern period, specifically during the late 17th and early 18th centuries. The novel follows various characters through a complex narrative that interweaves themes of economics, politics, and the scientific revolution.

Richard Baldus is not a widely recognized figure or concept in popular culture, academia, or other common references as of my last knowledge update in October 2023. It's possible that he could be a lesser-known individual, an emerging figure, or a fictional character.

Richard Canary is a professor in the Department of Mathematical Sciences at the University of Vermont. He is known for his work in mathematical biology, particularly in the areas of population dynamics and ecological modeling. His research often focuses on using mathematical techniques to better understand biological systems and phenomena.

Toshikazu Sunada is known as a Japanese mathematician who has made significant contributions to various areas of mathematics, particularly in the fields of algebraic geometry and combinatorial algebra. His work often involves the study of structures related to algebra and geometry, but he is perhaps best recognized for his contributions in developing mathematical theories and techniques.
