Extreme tribology is a specialized branch of tribology, which is the study of friction, wear, and lubrication between surfaces in relative motion. Extreme tribology focuses on understanding and analyzing the behavior of materials and lubricants under extreme conditions, including high temperatures, high pressures, vacuum environments, and other challenging conditions that can be encountered in various engineering applications.

Lubrication is the process of applying a substance, typically a lubricant, to the surface of moving parts to reduce friction and wear between them. This can enhance the efficiency and lifespan of machinery and mechanical systems. Lubricants can come in various forms, including oils, greases, solid lubricants, and even gases.

A rolling-element bearing is a type of bearing that uses rolling elements to reduce friction between moving parts. These bearings typically consist of an inner and outer ring, along with rolling elements such as balls or cylindrical rollers situated between them. The primary purpose of rolling-element bearings is to support and facilitate smooth rotational or linear motion while minimizing wear and energy loss. ### Key Features: 1. **Rolling Elements**: The most common rolling elements are balls and cylinders (rollers).

Pipe manufacture refers to the process of producing pipes, which are cylindrical tubes used for various applications, including transporting fluids (like water, oil, and gas), structural support, and construction. The manufacturing process involves several steps, materials, and technologies, depending on the type of pipes being produced (such as metal, plastic, or composite materials).

AN thread, also known as Army-Navy thread, is a type of standardized screw thread used primarily in military and aerospace applications, as well as in some civilian industries. AN threads are predominantly used for fasteners and components in aircraft, where high strength and reliability are crucial. Here are some key characteristics of AN threads: 1. **Unified Thread Form**: AN threads are generally based on the Unified Thread Standard (UN), which outlines the specifications for the thread profile, pitch, and dimensions.

Sander Greenland is a prominent statistician and epidemiologist known for his work in the fields of causal inference, meta-analysis, and statistical methods in epidemiology. He has contributed significantly to the development of methodologies for analyzing observational data and understanding the causal relationships in epidemiological studies. His work has influenced the way researchers interpret data and design studies in public health and clinical research. Greenland has published extensively in academic journals and is regarded as an important figure in biostatistics and epidemiological research.

William Farr (1807-1883) was a prominent English statistician and epidemiologist, often regarded as one of the founders of medical statistics. He is best known for his work in the development of vital statistics and for his contributions to understanding the relationship between health and environment. Farr played a key role in establishing methods for collecting and analyzing health data, such as mortality statistics, which were crucial for public health planning and policy.

William Guy could refer to various individuals or subjects depending on the context. Without additional information, it's difficult to determine exactly what you mean. Here are a few possibilities: 1. **William Guy (Physician)**: A British physician known for his contributions to medical education and public health in the 19th century. 2. **William Guy (Artist)**: A contemporary artist or historical figure, whose works might be recognized in various art circles.

Brian D. Ripley is a prominent statistician known for his contributions to the fields of statistical computing, spatial statistics, and the development of the R programming language. He has played a significant role in advancing statistical methods and tools, particularly in the context of geostatistics and spatial analysis. Ripley is also recognized for his work on statistical models and for authoring influential books and papers. One of his notable works includes "Spatial Statistics," which is widely referenced in the field.

William Sealy Gosset (1876–1937) was an influential Irish statistician known primarily for developing the concept of the t-distribution, which is widely used in statistical inference. He worked at the Guinness Brewery in Dublin, where he applied statistical methods to improve the quality control of brewing processes. Gosset published under the pseudonym "Student," which is how the t-distribution is often referred to as the "Student's t-distribution.

Data miners, in the context of data science and analytics, refer to professionals or automated systems that extract useful and actionable insights from large sets of data. The process of data mining involves various techniques from statistics, machine learning, and database systems to identify patterns, correlations, and trends within data that can inform decision-making, predict future outcomes, or reveal hidden relationships.

Survey methodologists are specialists who focus on the design, implementation, and analysis of surveys. They employ statistical principles and research methodologies to ensure that data collected through surveys are reliable, valid, and representative of the population being studied. Their work involves several key areas: 1. **Survey Design**: This includes selecting appropriate methodologies (e.g., online surveys, telephone interviews, face-to-face interviews) and developing effective questionnaires that minimize bias and lead to high-quality data collection.

"Relics" is the 75th episode of *Star Trek: The Next Generation*, which aired during the sixth season of the series on April 16, 1992. The episode is notable for featuring the return of the iconic character Montgomery "Scotty" Scott, played by James Doohan, who originally appeared in the original *Star Trek* series.

Cassini's laws refer to a set of three mathematical descriptions regarding the motion of a body in an orbit around another body, specifically in the context of a rotating body and its satellite. These laws are particularly relevant to the motion of the moons of planets, such as the Earth-Moon system or the various moons of Saturn, which were studied extensively by Giovanni Domenico Cassini in the late 17th century.

Dalí Paris is a museum dedicated to the works of the renowned surrealist artist Salvador Dalí. Located in the heart of Paris, specifically in the Montmartre district, the museum showcases a wide range of Dalí's art, including paintings, sculptures, and various other works that highlight his distinctive style and surrealistic approach. Dalí Paris aims to immerse visitors in the imagination and creativity of Dalí, offering a unique experience that reflects his contributions to the art world.

The Xu Guangqi Memorial Hall, located in Shanghai, China, is a memorial dedicated to Xu Guangqi, a prominent scholar, farmer, and politician during the Ming Dynasty (1368–1644). Xu is well-known for his contributions to science, agriculture, and the introduction of Western technology and knowledge to China, particularly through his collaboration with Jesuit missionaries like Matteo Ricci.

Maeve McCarthy could refer to various individuals or concepts, as it is not a unique name. Without more context, it is challenging to pinpoint a specific person or subject.
