Helen Abbey is a historical site located in Scotland, specifically on the banks of the River Forth in Clackmannanshire. It was established as a convent for the Cistercian Order in the 12th century, dedicated to St. Mary. The abbey played a significant role in the religious and cultural history of the region. Helen Abbey is known for its picturesque setting and the remnants of its original structure.

Joseph L. Fleiss (1923–2003) was a prominent American statistician, best known for his work in biostatistics and psychometrics. He made significant contributions to the field of statistics, particularly in areas such as categorical data analysis, agreement measures, and the development of statistical methods for clinical trials. Fleiss is widely recognized for his introduction of the kappa statistic, which is used to measure inter-rater agreement.

He is known for his work in causal inference, health outcomes research, and the application of statistical methods to public health issues. Hernán is a professor at Harvard University's T.H. Chan School of Public Health and has contributed significantly to the development of methodologies for observational studies, particularly in understanding causal relationships in public health data.

Karin B. Michels is a notable figure in the field of public health and epidemiology. She is particularly known for her work and research in nutrition, cancer epidemiology, and women's health. Michels has held academic positions, including at institutions like Harvard University, and has contributed significantly to understanding the relationship between diet and health outcomes.

Mark Lathrop might refer to different individuals depending on the context. One notable figure is Mark Lathrop, a prominent American geneticist known for his work in the field of genomics and personalized medicine. He has contributed significantly to research related to genetic mapping and understanding the genetic basis of various diseases.

Niels Keiding is a prominent Danish statistician known for his work in biostatistics and epidemiology. He has contributed significantly to survival analysis and statistical methods in medical research. Throughout his career, Keiding has been involved in various interdisciplinary projects, focusing on developing and applying statistical models to understand health data better.

The Schwarzschild metric is a solution to the Einstein field equations of general relativity that describes the gravitational field outside a spherical, non-rotating, and uncharged mass such as a planet or a non-rotating star. It is one of the simplest and most important solutions in general relativity, providing insights into the geometry of spacetime in the presence of a gravitational source.

The black hole stability conjecture is a theoretical idea in the field of general relativity and mathematical physics that pertains to the stability of black hole solutions to the equations of general relativity, particularly under small perturbations. In essence, the conjecture suggests that black holes, once they form and settle into equilibrium (typically after dynamic processes like a merger or collapse), are stable objects.

"Delisted applications" typically refer to applications (apps) that have been removed or deleted from an app store or marketplace, such as the Apple App Store or Google Play Store. There are several reasons why an application might be delisted: 1. **Policy Violations**: The app may have violated the app store's policies, terms of service, or guidelines. This could include issues related to content, security, user privacy, or user experience.

An **optical black hole** is a concept in the field of optics and experimental physics that refers to a medium or structure that can mimic the behavior of a gravitational black hole using light. Just as a gravitational black hole affects nearby matter and light through its immense gravitational pull, an optical black hole manipulates light in such a way that it creates an "event horizon," beyond which light cannot escape.

A ring singularity is a type of singularity that arises in certain solutions to the equations of general relativity, particularly in the context of rotating black holes, such as the Kerr black hole. Unlike a point singularity, which is a singularity that is concentrated at a single point (as found in a non-rotating, spherical black hole), a ring singularity is shaped like a ring or a torus.

The Thorne–Hawking–Preskill bet was a famous wager made in 1997 between three prominent physicists: Kip Thorne, Stephen Hawking, and John Preskill. The bet revolved around the nature of black holes and the information paradox, which questions whether information that falls into a black hole is lost forever or can be recovered. In essence, the bet was about whether information that falls into a black hole is truly irretrievable.

Spaghettification is a term used in astrophysics to describe the process by which objects are stretched and elongated due to extreme gravitational forces, particularly in the vicinity of a black hole. This phenomenon occurs because of the strong gravitational gradient present in such regions, meaning that the gravitational pull on an object (or a person) is significantly stronger at one end than at the other, especially as one gets closer to the black hole.

"A Mathematician's Apology" is a book written by the British mathematician G.H. Hardy, published in 1940. The work is a reflection on the aesthetics and philosophy of mathematics, as well as Hardy's thoughts on the nature of mathematical proof and creativity. In the book, Hardy famously defends pure mathematics, emphasizing its beauty and intellectual rigor, while contrasting it with applied mathematics, which he viewed as less elegant.

"Christmas tree" files refer to a specific way of organizing and displaying information in certain types of files, particularly in programming or configuration contexts. The term is often used to describe files that have a hierarchical structure resembling the shape of a Christmas tree, where there are multiple branches or levels of categories. The most common application of this term relates to source code repositories or configuration files in software development.

Beall's List is a controversial resource that compiles a list of "predatory" open access journals and publishers. Originally created by Jeffrey Beall, a librarian and scholar, the list was intended to help researchers identify journals that may not adhere to acceptable academic publishing standards. The term "predatory" refers to journals that exploit the author-pays model without providing proper editorial services, peer review, or other scholarly norms.

"Blacklisted by History" is a book written by M. Stanton Evans, published in 2007. The book primarily focuses on the history and legacy of the anti-communist figure Whittaker Chambers and the infamous Alger Hiss case, which was a significant political scandal in the United States during the early Cold War period.

Deplatforming refers to the act of removing or banning an individual, group, or organization from a platform, typically in the context of social media, online forums, or other digital spaces. This action is often taken by platform providers in response to behavior or content that is deemed to violate their terms of service, community guidelines, or laws.

The list of banned video games varies by country and can change over time due to evolving laws, social standards, and cultural sensitivities. Here are several notable examples of countries and some of the games that have been banned: ### United States - **Grand Theft Auto: San Andreas** - Controversies over violence and sexual content led to significant scrutiny. - **Manhunt 2** - Banned due to extreme violence and graphic content.
