"Discoveries" by Marco Micheli is a work that explores themes surrounding the exploration of the unknown, the nature of discovery, and the human experience in seeking knowledge.
Pappus's hexagon theorem is a result in projective geometry named after the ancient Greek mathematician Pappus of Alexandria. The theorem states that if you have a hexagon inscribed in two lines (i.e., pairs of opposite vertices of the hexagon lie on each of the two lines), the three pairs of opposite sides of the hexagon, when extended, will meet at three points that are collinear (lie on a straight line).
"Discoveries" is a well-known piece of music composed by Peter Birtwhistle, a contemporary British composer known for his innovative and often experimental approach to composition. The work is celebrated for its unique treatment of sound and texture, showcasing Birtwhistle's ability to blend various musical elements and styles.
"Discoveries" is a collection of short stories by Russian author Timur Kryachko. The book features a variety of narrative styles and explores themes related to human experience, relationships, and the intricacies of life. Kryachko's writing is known for its emotional depth and insight into the human condition, often blending introspection with vivid imagery.
"Discoveries" by Yoshisada Shimizu is a notable book that explores various themes, possibly touching on elements of culture, philosophy, or personal insights, depending on the subject matter of the work. However, specific details about the book or its content may not be widely available or well-known, given that Yoshisada Shimizu is not a mainstream author like some other figures in literature.
In the context of chemistry, a **hypercycle** refers to a model used in theoretical biology and the study of chemical evolution, particularly in relation to the origins of life. The concept was introduced by mathematician and theoretical biologist Manfred Eigen in the 1970s. A hypercycle is a cyclic sequence of macromolecules, such as RNA or proteins, that serve to catalyze each other's replication or metabolism in a cooperative manner.
Salvador Dalí was a prominent Spanish surrealist artist known for his imaginative and eccentric artworks that often explored themes of dreams, subconsciousness, and the bizarre. Born on May 11, 1904, in Figueres, Catalonia, Dalí became one of the most influential figures in 20th-century art. He is best known for his stunning and often bizarre paintings, which featured dreamlike imagery, distorted forms, and unexpected juxtapositions.
The Levi L. Conant Prize is an award given by the American Mathematical Society (AMS). It honors the memory of Levi L. Conant, who was a notable figure in the field of mathematics, particularly known for his contributions to mathematical education and his role in promoting mathematics. The prize is typically awarded for articles published in the AMS's publications that are aimed at a broad mathematical audience and that exhibit expository excellence.
The innermost stable circular orbit (ISCO) is a concept from general relativity that pertains to the orbits of objects around compact astrophysical objects, such as black holes or neutron stars. The ISCO represents the smallest orbit in which a test particle (like a small mass moving under gravitational influence) can stably orbit a massive body without spiraling into it due to gravitational or tidal forces. Here are key points about the ISCO: 1. **Stable vs.
Internal tides are oscillations or waves that occur within the ocean's thermocline, which is the layer of water between the warmer surface layer and the colder deep water. Unlike surface tides, which are generated by the gravitational forces of the moon and the sun acting on the oceans, internal tides are typically generated by the interactions of tidal forces with underwater features such as continental shelves, seamounts, and other topography.
The International Conference on the Physics of Semiconductors (ICPS) is a prominent scientific conference that focuses on the latest research and developments in the field of semiconductor physics. This conference typically brings together physicists, materials scientists, and engineers from around the world to discuss advances in the understanding of semiconductor materials, devices, and applications.
The International Framework for Nuclear Energy Cooperation (IFNEC), formerly known as the Global Nuclear Energy Partnership (GNEP), is a multilateral initiative that aims to promote the safe, secure, and sustainable use of nuclear energy for peaceful purposes. Established in 2006, IFNEC seeks to foster international collaboration in nuclear energy generation and technology while addressing concerns related to nuclear nonproliferation and sustainability.
The International Union for Vacuum Science, Technique and Applications (IUVSTA) is an international organization that focuses on promoting the science and technology related to vacuum systems and their applications. Founded in 1961, IUVSTA serves as a platform for scientists, engineers, and researchers working in various fields that utilize vacuum technology, such as surface science, thin films, materials science, and nanotechnology.
Tantalum has two stable isotopes: **Tantalum-181 (Ta-181)** and **Tantalum-180 (Ta-180)**. The most abundant isotope is Ta-181, which constitutes almost all naturally occurring tantalum.
Francium is a highly radioactive alkali metal with the symbol Fr and atomic number 87. It is one of the least stable elements on the periodic table, and it has no stable isotopes. The isotopes of francium are all radioactive, and the most commonly discussed isotopes are: 1. **Francium-223 (Fr-223)**: This is the most stable and the most naturally occurring isotope of francium, with a half-life of about 22 minutes.
The Iwahori–Hecke algebra is a mathematical structure that arises in the study of representation theory, particularly in the representation theory of the symmetric group and related algebraic objects, such as Coxeter groups and reductive algebraic groups. ### Definition The Iwahori–Hecke algebra, often denoted as \( \mathcal{H} \), is an algebra associated with a Coxeter group.
Jaan Einasto is an Estonian astrophysicist known for his significant contributions to the field of cosmology and astrophysics. Born on January 27, 1929, he is well-regarded for his research on the structure and dynamics of galaxies, as well as the large-scale structure of the universe. Einasto is particularly known for the "Einasto profile," which is a model used to describe the density distribution of dark matter in galaxies and galaxy clusters.

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.
