Galina Kurlyandskaya is a notable Russian mathematician, recognized for her contributions to mathematical logic, particularly in model theory, set theory, and combinatorial aspects of logic. She has been influential in advancing the field and has published numerous papers and works related to her areas of expertise.
Poly(pentafluorophenyl acrylate) is a polymer derived from the polymerization of pentafluorophenyl acrylate, which is an acrylate monomer containing a pentafluorophenyl group. The "pentafluorophenyl" refers to a phenyl ring (a six-carbon aromatic ring) that has five of its hydrogen atoms replaced with fluorine atoms.
Pondcrete is a type of material used in the construction of ponds and water features. It is a specialized concrete formulation designed to be waterproof and durable in aquatic environments. Pondcrete often contains additives that enhance its resistance to water permeation and biological growth, making it suitable for landscaping and garden ponds. In practical terms, Pondcrete can be used to create custom-shaped pond liners, walls, or other structures that need to withstand water exposure while providing a solid and stable base.
In engineering, particularly in the context of software development and project management, "alpha strike" typically refers to an early-stage focus on delivering a minimum viable product (MVP) or a foundational version of a product. It emphasizes rapidly building and testing a product to gather feedback, iterate, and make improvements. The term can also be used in other engineering disciplines to denote an initial phase of a project where essential components are developed to evaluate feasibility, performance, or integration.
In finance, **time consistency** refers to the concept that an individual's or a decision-maker's preferences and plans regarding future actions should remain consistent over time. This concept has implications for financial decision-making, investment strategies, and policy formulation. Here are a few key points regarding time consistency: 1. **Expectation and Future Actions**: A time-consistent decision maker will make plans today that they will want to stick to in the future.
Frame-dragging is a phenomenon predicted by Einstein's General Theory of Relativity, which describes how the rotation of a massive body influences the spacetime around it. When an object with a significant mass, such as a planet, star, or black hole, rotates, it "drags" the fabric of spacetime around with it. This effect is particularly pronounced near very massive and fast-rotating objects.
A dry port is an inland intermodal terminal that acts as a hub for the transfer of cargo between different modes of transportation, typically between rail and truck, while being connected to a seaport or a waterway. Dry ports are designed to facilitate the movement of goods by providing facilities for customs clearance, storage, and distribution, thereby reducing congestion at coastal ports and enhancing supply chain efficiency.
Turtle Island is a term commonly used in Indigenous North American folklore to refer to North America itself. The concept originates from various Indigenous creation stories, particularly among some Native American and First Nations cultures. In these narratives, the land is often depicted as being formed on the back of a giant turtle. One of the most well-known creation stories involves a woman known as Sky Woman, who falls from the sky and lands on the back of a great turtle.
Thomas Henning could refer to various individuals, but without additional context, it's difficult to pinpoint a specific person or topic.
Wulf Steinmann doesn't appear to be widely recognized or associated with any prominent figures, concepts, or entities as of my last knowledge update in October 2023. It’s possible that he may be a private individual or a professional not widely known in public contexts.
Ferenc Kalmár, whose name may refer to different individuals depending on the context, is commonly associated with a Hungarian mathematician and computer scientist.
Georg von Békésy was a Hungarian biophysicist who made significant contributions to the understanding of the mechanics of the inner ear and the perception of sound. Born on August 3, 1899, in Budapest, Hungary, he was awarded the Nobel Prize in Physiology or Medicine in 1961 for his research on the physical mechanisms of auditory perception.
Deepak Dhar is an Indian theoretical physicist and a prominent researcher in the field of statistical mechanics and complex systems. He is known for his work on various topics, including nonequilibrium statistical mechanics, biological physics, and the dynamics of complex networks. Dhar has made significant contributions to understanding phase transitions and critical phenomena in various physical systems.
Krishnaswamy Kasturirangan is an Indian space scientist and a notable figure in the field of space research. He played a pivotal role in the Indian space program, particularly with the Indian Space Research Organisation (ISRO). Kasturirangan was the chairman of ISRO from 1994 to 2001 and was instrumental in the development of several key projects, including the launch of satellites and the advancement of India's space technology.
P. Radhakrishnan is an Indian scientist known for his contributions to the field of space and aeronautics. He has held various prominent positions in India's space research organization, the Indian Space Research Organisation (ISRO). Notably, he served as the Chairman of ISRO from 2009 to 2014.
John Lighton Synge (1897–1995) was an Irish mathematician and physicist known primarily for his contributions to relativity theory and differential geometry. He is perhaps best recognized for his work in the fields of general relativity and its applications, particularly in the context of gravitational theory. Synge made significant contributions to the understanding of gravitational lensing and the behavior of light in curved spacetime.
Bunsaku Arakatsu (荒勝 文作) is a notable figure in the field of mathematics and is particularly recognized for his contributions to the field of mathematics education and research in Japan. However, details about his specific contributions and achievements might need to be clarified or expanded upon depending on the context you are referring to.
Liang Junwu is not a widely recognized term or name in common discourse as of my last knowledge update in October 2021. It could refer to a specific individual, a concept, or a term that has gained significance after that date.
Roald Sagdeev is a prominent Russian physicist known for his contributions to the fields of space physics and plasma physics. He was born on March 15, 1932, in the Soviet Union. Sagdeev is particularly recognized for his work on the interaction of solar wind with planetary atmospheres and magnetospheres, as well as for his role in various Soviet space missions.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
