Atomix is a puzzle video game that was originally developed by the game studio "AMG Games" and released in the early 1990s. The game involves navigating a series of levels where players must assemble molecules by moving and positioning atoms within a grid. The gameplay typically requires strategic thinking and planning, as players must figure out how to manipulate the atoms to form the correct structures while overcoming various obstacles.
The Principle of Similitude is a concept primarily used in engineering and fluid mechanics, which deals with the relationship between model systems and their real-world counterparts. This principle allows engineers and scientists to create scaled-down versions (models) of physical systems to study their behavior, performance, or properties without the need for full-scale experiments, which can be costly or impractical.
Guy Terjanian is a name that may refer to different individuals or contexts, but one notable person is an academic and author known for his work in the field of economics and political science. He has been involved in various scholarly and professional activities, including research, teaching, and writing.
Karin Erdmann is a relatively common name, and without specific context, it could refer to different individuals. One notable person with that name is a German artist and designer known for her work in fields like sculpture or installation art.
Peter Cameron is a noted mathematician known for his contributions to various areas of mathematics, particularly in combinatorics, algebra, and graph theory. He has made significant strides in the study of permutation groups, finite geometries, and design theory. Cameron has published numerous papers and has contributed to the mathematical community through his research and teaching. In addition to his research work, Peter Cameron has held academic positions at various institutions and has been involved in mathematical education and mentorship.
Thomas Harriot (1560–1621) was an English mathematician, astronomer, and explorer, known for his contributions to various fields of science and for being one of the first to use a telescope for astronomical observations in England. He is perhaps best known for his work "A Brief and True Report of the New Found Land of Virginia," in which he documented the flora, fauna, and indigenous peoples of the region during his time as a member of an expedition to the Americas.
The Curta is a small, portable mechanical calculator that was invented by the Austrian engineer Victor G. Sch alleger in the 1930s. It is notable for its compact design and efficiency, resembling a pepper grinder in appearance. The Curta can perform basic arithmetic operations such as addition, subtraction, multiplication, and division. The device works using a system of gears and rotary mechanisms, allowing calculations to be made quickly and inexpensively.
Aether theories refer to a historical set of concepts in physics that proposed the existence of a substance known as "aether" (or "ether") as a medium for the propagation of light and other electromagnetic waves. Here is an overview of the development and eventual rejection of these theories: 1. **Historical Context**: In the late 19th century, physicists believed that light needed a medium to travel through, similar to how sound travels through air.
Lehmer's totient problem is an unsolved problem in number theory, specifically related to the Euler's totient function \( \phi(n) \). The Euler's totient function \( \phi(n) \) counts the number of positive integers up to \( n \) that are coprime to \( n \).
Albert Tarantola was a prominent French geophysicist known for his contributions to the field of inverse problems and seismic data analysis. He is particularly recognized for developing theories and methods in the context of geophysical exploration and imaging. His work has had a significant impact on the way geophysical data, such as seismic data, is interpreted and used to model subsurface structures.
Wick rotation is a mathematical technique used primarily in quantum field theory and statistical mechanics to relate problems in particle physics to problems in statistical physics. Named after the physicist Giovanni Wick, this technique involves a transformation of the time coordinate in a Minkowski spacetime formulation from real to imaginary values.
Antithetic variates is a variance reduction technique used in the context of Monte Carlo simulation. The main purpose of this technique is to improve the efficiency of the simulation by reducing the variance of the estimator. The idea behind antithetic variates is to generate pairs of dependent random variables that are negatively correlated. This negation helps to balance out the fluctuations that might occur in the estimated outcomes.
The Bureau of Oceans and International Environmental and Scientific Affairs (OES) is a division of the U.S. Department of State. Its primary focus is to address global challenges related to oceans, the environment, and scientific issues. The bureau plays a crucial role in promoting U.S. interests in these areas by engaging in international negotiations, developing policies, and collaborating with other countries and international organizations.
The Amor asteroids are a group of near-Earth asteroids that have orbits that are primarily outside Earth's orbit but can come close to it. The term "Amor asteroid" refers to those objects that do not cross Earth's orbit but can approach it closely. They are named after the asteroid 1221 Amor, which was discovered in 1932.
"Die Reihe" was a significant avant-garde publication that emerged in the mid-20th century, particularly focused on contemporary music and its theoretical aspects. Founded in 1955 by composers and theorists, including Herbert Eimert and Karlheinz Stockhausen in Germany, the journal played a critical role in the development and dissemination of new music concepts and techniques, particularly related to serialism and electronic music.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
