Garrett Birkhoff (1911–1996) was an American mathematician known for his contributions to various fields, including algebra and lattice theory. He is particularly recognized for his work in universal algebra and for co-authoring the influential book "Lattice Theory" with co-author Paul Barkley, which helped formalize the study of lattices in mathematics.
Fridrikh Karpelevich is a notable figure in the field of mathematics, particularly known for his work in the areas of algebra and number theory.
A wood screw pump is a type of positive displacement pump that utilizes the principle of a screw mechanism to move fluids. The design is based on the Archimedes screw, which is an ancient device used for lifting water. In a wood screw pump, a helical screw enters a cylindrical casing, and as the screw rotates, it moves fluid along its length.
In the context of chemistry and crystallography, a point group is a set of symmetry operations that describe the symmetrical properties of a particular molecule or crystal structure. These operations include rotations, reflections, and inversions that leave at least one point (usually the center of the molecule or crystal) unchanged.
Hilary Priestley is a notable figure in the field of mathematics, particularly known for her work in probability theory and stochastic processes. She has made significant contributions to the understanding of stochastic ordering and decision theory. Priestley has authored various academic papers and has also been involved in teaching and mentorship in mathematics.
Jim Coykendall is a notable figure in the field of educational technology and instructional design. He is known for his contributions to the development of online education and training programs. Coykendall has worked on various initiatives to enhance learning experiences through the use of technology.
Hyman Bass is an American mathematician known for his contributions to algebra, particularly in the areas of algebraic topology, homological algebra, and representation theory. He is well-known for his work on group cohomology and other topics that bridge algebra and topology. Bass has also been involved in mathematical education and has advocated for improving math education at various levels.
"Ina Kersten" does not appear to correspond to any widely recognized term, concept, or notable individual based on the information available up to October 2023. It's possible that it could be a person's name, a character in a specific context, or a reference that has come to prominence after my last update.
László Fuchs may refer to a number of individuals, but one notable person with that name is a Hungarian-born mathematician known for his contributions to various fields in mathematics.
Joseph Wedderburn is a notable figure in the field of mathematics, particularly known for his contributions to algebra and commutative algebra. He is best recognized for his work on the Wedderburn-Artin theorem, which characterizes semisimple algebras over a field. His contributions laid foundational aspects of modern algebra, including insights into the structure of rings and modules.
Leonard Eugene Dickson (1874–1954) was a prominent American mathematician known for his work in algebra, number theory, and the history of mathematics. He made significant contributions to various areas, particularly in the theory of algebras and the study of linear transformations. Dickson is perhaps best known for his series of books on the theory of numbers and algebra, including "History of the Theory of Numbers," which is a comprehensive account of the development of number theory.
Martin Liebeck is a mathematician known for his work in group theory, algebra, and combinatorics. He has been involved in research related to the representation theory of finite groups and has made contributions in the area of symmetric functions and algebraic geometry. In addition to his research, Liebeck has been recognized for his contributions to mathematics education and has authored or co-authored several academic papers and books.
Peter Rosenthal could refer to various individuals, but one prominent figure is a professor and mathematician known for his work in the field of mathematics, particularly in topology and combinatorics. He may also be recognized for his contributions to research and education within mathematics.
Masatoshi Gündüz Ikeda is a Japanese theoretical physicist known for his contributions in the field of condensed matter physics, quantum mechanics, and statistical mechanics. He has authored and co-authored numerous scientific papers and has been involved in various research projects. His work often focuses on understanding complex physical systems and phenomena, which may include topics like quantum phase transitions, many-body physics, and non-equilibrium systems.
Moshe Meiselman is a prominent Orthodox Jewish rabbi and scholar, known for his expertise in Talmud and Jewish law. He has made significant contributions to Jewish education and has been involved in various communal and educational initiatives. He is associated with the Orthodox Jewish community and has taught at several institutions, focusing on the intersection of traditional Jewish texts and modern issues. Additionally, he has published works in the field of Jewish thought and law.
Muriel Kennett Wales is not widely recognized in public domain sources or historical records. It's possible that the name refers to a private individual or a lesser-known figure.
Nicolae Popescu could refer to a few different things, depending on the context. 1. **Nicolae Popescu (the Romanian footballer)**: He is a professional football player from Romania, often playing as a defensive midfielder or defender. He has been known to play in various European leagues and for the Romanian national team.
As of my last knowledge update in October 2023, "Nissan Deliatitz" does not appear to correspond to any well-known Nissan vehicle, model, or concept. It is possible that it might be a typographical error, a lesser-known term, or a very recent development that has emerged after my last update.
Otto Hesse is a name that may refer to multiple individuals, but one notable figure is a German mathematician known for his contributions to mathematics in the 19th century. He is particularly recognized for his work in algebra and analysis, although detailed information about his life and contributions may not be as widely known as those of other prominent mathematicians.

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.
