Einstein's static universe, proposed in 1917, is a cosmological model introduced by Albert Einstein in response to the prevailing views about the universe during his time. Before the advent of modern cosmology, the universe was widely thought to be static and unchanging. To reconcile his general theory of relativity with the idea of a static universe, Einstein introduced the cosmological constant (denoted by the Greek letter Λ) into his field equations of general relativity.
A build light indicator is a visual signaling device, commonly used in software development and continuous integration (CI) environments, to provide real-time feedback on the status of a software build process. These devices typically use colored lights (such as green and red) to indicate whether the latest build of the software is successful or has failed.
The Einstein–Szilard letter is a famous letter written by physicist Leo Szilard and co-signed by Albert Einstein in August 1939. This letter is notable for its role in alerting the United States government to the potential development of atomic weapons. In the letter, Szilard warned President Franklin D. Roosevelt about the possibility of Nazi Germany developing atomic bombs, given the recent discoveries in nuclear fission by scientists in Europe.
Corrado Segre (1859–1924) was an Italian mathematician known for his contributions to algebraic geometry and the theory of algebraic curves. He played a significant role in the development of these fields during the late 19th and early 20th centuries. Segre made notable advances in the study of projective geometry and the geometry of algebraic varieties, and he was also involved in the foundations of modern algebraic geometry.

Pierre Bieliavsky is a notable mathematician, primarily recognized for his contributions to the fields of harmonic analysis, representation theory, and the study of automorphic forms. He is particularly known for his work in the study of the properties of mathematical objects and their interactions, as well as for his involvement in various mathematical projects and collaborations.
Simon Donaldson is a prominent British mathematician known for his contributions to differential geometry and gauge theory, particularly in relation to topology and the geometry of four-dimensional manifolds. Born on August 5, 1957, he is best known for his work in the mid-1980s, where he proved important results concerning the topology of four-manifolds and established the existence of certain classes of manifold that cannot be constructed using standard techniques from algebraic topology.
A Spaltenstein variety is a specific type of algebraic variety that is studied in the context of representation theory and algebraic geometry, particularly in relation to the study of finite dimensional representations of algebraic groups or algebraic varieties. Spaltenstein varieties arise in the context of the so-called "nilpotent cones." More specifically, they can be associated with certain types of objects called "nilpotent elements" in the representation theory of Lie algebras or algebraic groups.
The Taniyama group, named after mathematician Yutaka Taniyama, is a group in the context of number theory that is closely related to the study of elliptic curves and modular forms. It is particularly famous for its connection to the Taniyama-Shimura-Weil conjecture, which posited that every elliptic curve over the rational numbers is associated with a modular form.
Dominican amber is a type of fossilized tree resin that originates from the Dominican Republic, primarily from the regions of the Cordillera Central and surrounding areas. It is estimated to be around 20 to 40 million years old, dating back to the Oligocene to Miocene epochs.
The Finite Lattice Representation Problem is a concept in the field of lattice theory, which deals with partially ordered sets that have specific algebraic properties. In particular, this problem pertains to determining whether a given finite partially ordered set (poset) can be represented as a lattice.
As of my last update in October 2023, "Monus" could refer to a few different things depending on the context. It may refer to: 1. **Monus (Currency)**: In some contexts, "Monus" might refer to a digital currency or token. It's essential to check specific cryptocurrency platforms or forums for the most recent developments in digital currencies.
Will Hay was a British comedian, actor, and filmmaker, best known for his work in the early to mid-20th century. He was born on December 6, 1888, in Stockton-on-Tees, England, and he passed away on April 18, 1949.

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.
