Invariant-based programming is a software development methodology that emphasizes the use of invariants—conditions that must hold true during the execution of a program—throughout the lifecycle of a program. Invariants are properties or constraints that remain unchanged under specific conditions, providing a way to reason about and maintain the correctness of a program. ### Key Concepts 1.

The Iodine Satellite refers to a satellite developed by the company Iodine as part of its efforts to provide advanced satellite-based services.

He is recognized for his work in developing techniques in statistical sampling and for his role in advancing the use of statistics in various practical applications. Oncley's research has had a lasting impact on fields that utilize statistical analysis, including economics, social sciences, and public health.

John Smeaton (1724–1792) was an English civil engineer and is often regarded as the "father of civil engineering." He is best known for his work in designing lighthouses and waterworks, as well as advancements in the construction of concrete.

The Joint Astronomy Centre (JAC) was a research institute located in Hilo, Hawaii. It was established to support astronomical research and to operate observatories, primarily the James Clerk Maxwell Telescope (JCMT) and the UK Infrared Telescope (UKIRT). The JAC played a key role in providing scientific and technical support to the global astronomical community, facilitating the use of these telescopes for research purposes.

Joseph Rosen is a professor known for his work in the field of mathematics, particularly in areas such as mathematical logic and the foundations of mathematics. He has made contributions to various topics, such as model theory and set theory. However, it is important to verify the specific context in which you are asking about him, as there may be multiple individuals with that name in academia.

Jump search is an efficient search algorithm for finding an element in a sorted array. It works by dividing the array into blocks and then performing a linear search within a block. The key idea is to reduce the number of comparisons compared to a simple linear search by "jumping" ahead by a fixed number of steps over the array instead of checking each element.

Kettle logic is a term used in legal theory and logic to describe a situation where a person makes multiple, contradictory arguments or assertions to support a particular position. It is named after the philosopher H.L.A. Hart, who used the notion to illustrate how certain legal arguments can be constructed in a way that they rely on multiple, inconsistent premises. The concept can be understood as follows: someone might present several reasons for a conclusion that cannot all be true at the same time.

Lace cards are typically small, decorative cards made from lace or featuring lace-like designs.
