The Japan–North Korea Pyongyang Declaration, signed on September 17, 2002, is a significant agreement between the governments of Japan and North Korea. This agreement was reached during a summit in Pyongyang, where then-Japanese Prime Minister Junichiro Koizumi met with North Korean leader Kim Jong-il.
Reinforced thermoplastic pipe (RTP) is a type of piping system made from thermoplastic materials that are reinforced with fibers or other materials to enhance their strength and performance characteristics. RTP combines the advantages of thermoplastics, such as corrosion resistance, lightweight nature, and flexibility, with the increased mechanical strength provided by the reinforcement.
Retrodiction is the process of inferring past states or events based on current or present data and knowledge. It is a form of reasoning that works in the opposite direction of prediction. While prediction looks forward to forecast future events or states from current information, retrodiction seeks to reconstruct or deduce what must have happened in the past to result in the current circumstances. Retrodiction is often used in various fields, including science, history, and data analysis.

As of my last update in October 2023, there is no widely known individual named Samuel Christian Hollmann in major news, literature, or public records. It's possible that he could be a private individual, a figure who has gained prominence after that date, or a character in a specific context such as literature or media.
Scottish biophysicists are scientists from Scotland who specialize in the field of biophysics, which is an interdisciplinary area that applies the principles and methods of physics to understand biological systems. Biophysicists study the physical properties of biological molecules, cells, and processes, often using techniques from physics to explore questions related to molecular structure, dynamics, and interactions.
A light-year is a unit of distance that represents how far light travels in one year in the vacuum of space. Since light moves at a speed of about 299,792 kilometers per second (or approximately 186,282 miles per second), a light-year is equivalent to about 9.46 trillion kilometers (or about 5.88 trillion miles).
The Shirshov Institute of Oceanology, officially known as the P.P. Shirshov Institute of Oceanology, is a prominent research institution located in Moscow, Russia. It is part of the Russian Academy of Sciences and focuses on oceanographic research, including marine biology, physical oceanography, geological processes in the ocean, and the study of marine ecosystems. The institute is named after the Russian oceanographer P.P. Shirshov, who made significant contributions to the field.
Simultaneous Perturbation Stochastic Approximation (SPSA) is an optimization technique used primarily for estimating the minima or maximizing the performance of a function that is typically noisy and possibly non-differentiable. It is especially useful in situations where evaluating the function is expensive, such as in simulations, control problems, or real-world applications where measurements have inherent noise.
Sir Benjamin Collins Brodie, 1st Baronet (1783–1862) was a notable British surgeon and anatomist during the 19th century. He was born in England and became well-known for his contributions to surgery and the understanding of human anatomy. Brodie was particularly recognized for his surgical techniques and advancements in the treatment of diseases, especially those affecting the joints and bones.
The small retrosnub icosicosidodecahedron is a complex geometric shape classified as an Archimedean solid. Specifically, it is a type of polyhedron that possesses both regular and irregular faces, exhibiting a unique combination of symmetries and characteristics. Key features of the small retrosnub icosicosidodecahedron include: 1. **Faces**: It is composed of a mixture of faces, including triangles, squares, and pentagons.
As of my last update in October 2023, "Karl Rohn" does not appear to be a widely recognized person, term, or concept in popular culture, history, or academia. It's possible that it could refer to a specific individual who is not well-known or a misspelling of another name.
The Karma Police is a surveillance program allegedly operated by the Indian government's law enforcement agencies. It emerged from reports about a controversial initiative that involves monitoring social media activity and other online communications to identify and track individuals who engage in behavior deemed harmful or subversive. The program has raised concerns regarding privacy and civil liberties, as critics argue that it could lead to the suppression of dissent and the silencing of opposition voices.
Kazimieras Ragulskis is a Lithuanian mathematician known for his contributions in the field of mathematics, particularly in areas like topology, algebra, and mathematical education.
KCNA4 refers to the gene that encodes the potassium voltage-gated channel subfamily A member 4, which is a protein involved in the formation of ion channels that regulate the flow of potassium ions across cell membranes. This protein is significant in various physiological processes, including muscle contraction, neuronal signaling, and the maintenance of the resting membrane potential in cells.
Kenneth Arrow (1921–2017) was an influential American economist and a key figure in modern economic theory. He is best known for his work on general equilibrium theory and for the Arrow's Impossibility Theorem, which demonstrates that no voting system can convert individual preferences into a collective decision while meeting a specified set of fair criteria. This theorem has profound implications for social choice theory and the fields of economics and political science.

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
