Joseph Petzval was a 19th-century Hungarian mathematician and optician, best known for his significant contributions to the field of photography and lens design. He is particularly recognized for inventing the Petzval lens in 1840, which was one of the first lenses designed specifically for portrait photography.

In category theory, a **Kan extension** is a construction used to generalize the idea of extending functions or functors across categories. More specifically, Kan extensions can be thought of as a way to extend a functor defined on a small category to a functor defined on a larger category, while maintaining certain properties related to limits or colimits. There are two types of Kan extensions: **left Kan extensions** and **right Kan extensions**.

Kathryn Zurek is an American physicist known for her work in the field of theoretical physics, particularly in the areas of quantum gravity and black hole physics. She is associated with research in gravitational waves and other aspects of astrophysics. Beyond her research, she is also noted for her engagement in science communication and education.

Kempe's universality theorem is a significant result in the field of graph theory and automata theory, specifically concerning the properties of certain types of logical structures. The theorem states that every finite structure can be embedded in a sufficiently large and well-behaved universal structure. In more technical terms, let’s consider a vocabulary (a set of symbols that represent functions, relations, and constants).

The Ken Kennedy Award is presented annually to recognize an individual who has made significant contributions to the field of computing, particularly in the areas related to the use of computing to solve large-scale, complex problems. Named in honor of Ken Kennedy, a prominent computer scientist known for his work in high-performance computing and programming languages, the award aims to highlight the importance of leadership and innovation in the field.

Kenneth Allen is an American physicist known for his contributions to the field of physics, particularly in the areas of experimental condensed matter physics and materials science. While he may not be as widely recognized as some other physicists, his work typically involves research on various physical phenomena and materials at the microscopic level.

Name collision refers to a situation where two or more entities, such as domain names, application names, or variable names in programming, conflict because they use the same identifier. This can lead to ambiguity and confusion in systems that rely on precise naming conventions.

Konrad Talmont-Kamiński is a scholar known for his work in the fields of philosophy of language, logic, and the philosophy of mind. He is associated with discussions surrounding topics such as consciousness and the nature of meaning.
