Robert Henry Risch does not appear to be a widely recognized public figure in historical or contemporary contexts up to my last knowledge update in October 2023. It is possible that he may be a private individual or someone who has gained attention more recently.

Robert MacMillan could refer to various individuals, as it is not an uncommon name. One prominent person with that name is Robert MacMillan, a former Canadian professional ice hockey player. He played in the National Hockey League (NHL) over the course of his career.

The Robertson-Webb query model is a theoretical framework used in the fields of information retrieval and information filtering. It was developed to provide a more nuanced understanding of how queries can be structured and their impact on the retrieval of relevant information from large datasets, such as databases or search engines.

A robot scientist is an autonomous or semi-autonomous robotic system designed to conduct scientific research. These robots can perform tasks traditionally carried out by human researchers, including formulating hypotheses, designing experiments, running experiments, analyzing data, and drawing conclusions. The aim of a robot scientist is to accelerate the pace of scientific discovery by automating routine and repetitive tasks, thereby allowing human researchers to focus on more complex and creative aspects of the research process.

Robustness of complex networks refers to the ability of a network to maintain its integrity and functionality in the face of failures, attacks, or other disturbances. It assesses how well a network can resist disruptions while still performing its intended functions. Robustness is a critical feature of various types of networks, including social, biological, technological, and infrastructure networks.

Roger Carter was a British mathematician known for his contributions to the fields of algebra and geometry, particularly in the area of group theory and its applications. He is often recognized for his work on the representation theory of groups, particularly in relation to finite groups and algebraic structures. Carter is also known for his influential textbook "Simple Groups of Lie Type," which has been a significant resource in the study of finite simple groups.

Rolf Widerøe was a Norwegian physicist and engineer best known for his pioneering work in the field of particle accelerators. Born on June 9, 1902, in Norway, he made significant contributions to the development of techniques for accelerating charged particles, particularly through the invention of the Widerøe accelerator. This device is a type of linear accelerator used to accelerate ions and is considered one of the early forms of particle accelerators.

Ole Rømer, a Danish astronomer, is credited with the first quantitative measurement of the speed of light in the late 17th century. In 1676, Rømer observed the motion of Jupiter's moon Io and noted variations in its orbital period depending on the Earth’s distance from Jupiter. He realized that these discrepancies were due to the finite speed of light.

Ronald G. Amundson is a notable figure in the fields of philosophy and science, particularly known for his contributions to the philosophy of biology, environmental philosophy, and the philosophy of science. His work often focuses on the relationships between scientific concepts, particularly in genetics and evolution, and their philosophical implications. Amundson is recognized for exploring how scientific practices and theories shape our understanding of the natural world.

As of my last update in October 2021, "Ross Bank" does not refer to a widely recognized financial institution or concept. It is possible that it could refer to a local bank, a specific branch, or a financial service in a particular region that has emerged after my last update. Alternatively, it might be a name associated with a specific individual or a business in a non-banking context.

Roy Selwyn-Smith is a fictional character from the 1985 novel "The Fountains of Paradise" by Arthur C. Clarke. He is an engineer involved in the construction of a space elevator, which is a concept central to the story. The novel explores themes of technology, ambition, and the relationship between humanity and the cosmos.

Ruby B. Lee is an American electrical engineer and a notable figure in the field of computer architecture. She is particularly recognized for her contributions to the areas of computer architecture, power-aware computing, and computer security. Lee has held various academic and professional positions, including serving as a professor at Princeton University. She has also contributed to the development of various technologies and has published numerous papers in her field.

The SABIO-Reaction Kinetics Database is a comprehensive database that provides detailed information about reaction kinetics, including rate constants, reaction mechanisms, and experimental conditions for various chemical reactions. It serves as a valuable resource for researchers in chemistry, biochemistry, and related fields by collecting and curating data from scientific literature.

Safety glass is a type of glass that is designed to minimize the risk of injury when broken. It is made to be more resistant to breaking and to shatter into small, less harmful pieces rather than sharp shards that can cause serious injury. There are several types of safety glass, each with specific applications and manufacturing processes, including: 1. **Tempered Glass**: Also known as toughened glass, it is produced by heating glass to high temperatures and then rapidly cooling it.

Sally C. Morton is an accomplished statistician and academic known for her work in statistical methodology, particularly related to public health and medical research. She has held various academic positions and leadership roles in several universities, such as the University of Pittsburgh, where she has been involved in research and education in statistics. Morton has also contributed significantly to the development of statistical methods for examining health disparities and improving health outcomes.

Sample mean and covariance are statistical measures that help describe the properties of a dataset. ### Sample Mean The **sample mean** is a measure of central tendency that represents the average of a set of observations. It is calculated by summing all the values in the sample and then dividing by the number of observations in that sample.

Samuel Tolver Preston was a notable American mathematician, primarily recognized for his contributions to number theory and combinatorics. He is perhaps best known for his work on the theory of partitions and for the invention of Preston's theorem, which relates to the combinatorial properties of partitions. In addition to his mathematical research, he also made his mark as an educator, influencing many students in the field.

The San'ao Nuclear Power Plant is a nuclear power facility located in the Zhejiang province of China, near the town of San'ao. It is part of China's efforts to diversify its energy sources and reduce dependence on fossil fuels. The plant consists of several reactors designed to generate electricity through nuclear fission. As of my last update, the San'ao Nuclear Power Plant was known for its involvement in China's expansion of nuclear energy capacity as part of its broader energy strategy.

Sandra Mitchell Hedetniemi is a prominent figure in the field of mathematics and computer science, particularly known for her work in graph theory and network theory. She has contributed to various research areas and published numerous academic papers throughout her career. Hedetniemi has also been involved in advocating for diversity and inclusion within the STEM fields.

A catastrophe bond (or cat bond) is a type of insurance-linked security (ILS) that allows investors to provide capital to insurers and reinsurers in exchange for high-yield returns. These bonds are designed to raise funds for insurance coverage against catastrophic events, such as natural disasters (hurricanes, earthquakes, floods, etc.). Here’s how catastrophe bonds typically work: 1. **Issuance**: An insurance company or a special purpose vehicle (SPV) issues the bond to investors.
