In logic and philosophy, a **proposition** is a declarative statement that expresses a judgment or opinion that can be evaluated as true or false. Propositions are the building blocks of logical reasoning and are used in various fields, including mathematics, computer science, and linguistics. Here are some key points about propositions: 1. **Truth Value**: A proposition has a truth value, meaning it is either true (T) or false (F).

Tychism is a philosophical term that refers to the belief in or emphasis on chance or randomness as a fundamental aspect of the universe, particularly in the context of natural processes. The word is derived from the Greek "tykhē," meaning fortune or chance. In philosophy, zejchism is often associated with the ideas of William James and Charles Sanders Peirce, who argued that chance events play a significant role in the development of complex systems and the evolution of life.

A benthic lander is an instrument or platform designed for studying the benthic zone, which is the lowest ecological zone in a body of water, including oceans, lakes, and rivers. This zone encompasses the sediments and the organisms living on or in the sediments at the bottom of these water bodies. Benthic landers are typically equipped with various scientific instruments and sensors to collect data on physical, chemical, and biological parameters in the benthic environment.

Byung-Chul Han is a South Korean-born philosopher and cultural theorist based in Germany, known for his work on contemporary society, culture, and issues such as technology, capitalism, and the nature of happiness. Born on April 15, 1959, Han has written extensively on a variety of topics, often focusing on the implications of neoliberalism and digital culture. His ideas explore how these forces shape individual subjectivity, relationships, and social dynamics.

Kiyoshi Itô was a renowned Japanese mathematician, best known for his groundbreaking work in stochastic calculus.
