He proposed the concept of the electron and was involved in the early development of atomic theory.
Sweden has a rich history of contributions to mathematics across various centuries. Here's a brief overview of some notable Swedish mathematicians by century: ### 17th Century - **Göran Heinrich (1601-1667)**: Often considered among the early contributors to Swedish mathematics. ### 18th Century - **Anders Celsius (1701-1744)**: Known for developing the Celsius temperature scale, but he also made contributions to mathematics, particularly in trigonometry and astronomy.
Swiss mathematicians have made significant contributions to mathematics throughout various centuries. Here is a brief overview of notable Swiss mathematicians by century: ### 17th Century - **Jacob Bernoulli (1654–1705)**: Known for his work in probability and for the Bernoulli numbers, as well as contributions to calculus and mathematical analysis.
Turkish mathematicians have made significant contributions to mathematics throughout various centuries, particularly in the context of the Ottoman Empire and the modern Republic of Turkey. Here’s an overview of notable Turkish mathematicians categorized by century: ### 15th - 17th Centuries - **Ali Qushji (c. 1403–1474)**: A mathematician and astronomer, he made important contributions to astronomy and was involved in the development of Islamic mathematics.
Emanuel Beke does not appear to be a widely recognized figure or term in common knowledge or public discourse as of my last update in October 2023. It's possible that you may be referring to a lesser-known individual, a concept, or a specific context that hasn't gained significant media attention.
Gustav von Escherich is best known as the German bacteriologist who first described the bacterium Escherichia coli, commonly referred to as E. coli, in 1885. E. coli is a type of bacteria that is normally found in the intestines of healthy humans and animals, where it plays a critical role in digestion and overall gut health. Some strains of E.
Gusztáv Rados is a Hungarian mathematician known for his contributions to various areas in mathematics, particularly in number theory and the theory of functions. Notably, he has worked on problems related to modular forms and their applications.
Gyula Vályi is a Hungarian name that may refer to different individuals or topics, but without more specific context, it's hard to provide a definitive answer. If you are referring to a person, it could be an academic, a public figure, or someone notable in a particular field.
Jean Trembley is a character often associated with a popular anecdote or joke in the realm of mathematics and computer science, particularly in the context of discussing the concept of probabilistic reasoning or combinatorial problems. The name is used in various contexts, such as in examples within textbooks or lectures to illustrate principles or to present humorous scenarios. It’s important to note that the specifics can vary, and in some cases, "Jean Trembley" may refer to different individuals or concepts depending on the context.
Nicolas Fatio de Duillier (1664–1753) was a Swiss mathematician and physicist known for his contributions to mathematics, particularly in the fields of geometry and calculus. He is perhaps best known for his work in the later development of Newtonian physics and for his association with notable contemporaries such as Isaac Newton and Gottfried Wilhelm Leibniz.
Several mathematicians and scholars contributed to the development of Islamic inheritance laws, which are based on the principles outlined in Islamic texts like the Quran and Hadith. One notable figure in this field is **Abu al-Hasan al-Mawardi** (974–1058), who was an Islamic jurist and scholar. He wrote extensively on inheritance laws and their applications within Islamic jurisprudence.
Zdzisław Krygowski is a name associated with various fields, particularly in the context of Polish history or culture. However, as of my last knowledge update in October 2023, there isn't a widely recognized figure named Zdzisław Krygowski that stands out prominently in global contexts. It's possible that he could be known in a specific academic, cultural, or professional setting, but there is limited information available about him in mainstream sources.
Elwin Bruno Christoffel was a Dutch mathematician born on June 16, 1825, and died on November 24, 1900. He is best known for his contributions to differential geometry and algebra.

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.
