The 16th century was a significant period in the history of mathematics, marked by the transition from medieval to modern mathematical thinking. Several mathematicians played key roles in the development of mathematical concepts during this time.
The 17th century was a pivotal time in the history of mathematics, marked by significant advancements and the development of new concepts that laid the foundation for modern mathematics. Notable mathematicians from this period include: 1. **René Descartes (1596–1650)**: Often considered the father of modern philosophy and analytic geometry, Descartes developed the Cartesian coordinate system, linking algebra and geometry. His work "La Géométrie" introduced methods for expressing geometric shapes algebraically.
The 4th century BC was a significant period for mathematics, particularly in ancient Greece, where many advancements were made that laid the groundwork for future mathematical thought. Here are some notable mathematicians and contributions from that era: 1. **Euclid**: While Euclid is more commonly associated with the 3rd century BC, he was influenced by mathematicians from the 4th century. His work, particularly the "Elements," is foundational in geometry.
"Burundian mathematicians" refers to mathematicians from Burundi, a small landlocked country in East Africa. While the country may not be widely recognized for a large number of prominent mathematicians compared to some other nations, there are individuals from Burundi who have contributed to the field of mathematics, whether through research, education, or application in various sectors.
Armenian mathematicians have made significant contributions to various fields of mathematics over centuries. Their work spans from ancient times to modern-day and covers areas such as number theory, geometry, algebra, and mathematical physics. ### Historical Context - **Ancient Contributions**: The earliest Armenian mathematicians date back to antiquity, influenced by Greek and Persian mathematics. Notable figures include Anania Shiraz and others who contributed to the mathematical knowledge of their time.

Malta, a small island nation in the Mediterranean, has produced several notable mathematicians throughout history, contributing to various fields such as number theory, geometry, and applied mathematics.
Belgian mathematicians have made significant contributions to various fields of mathematics throughout history. Here are a few notable Belgian mathematicians and their contributions: 1. **Georges Lemaitre (1894-1966)**: Astronomer and mathematician, he is best known for formulating the Big Bang theory, which has profound implications in cosmology. He also contributed to the field of units and measures in physics.
Bengali mathematicians refer to mathematicians from the Bengali ethnic group, primarily associated with the Bengal region, which includes the Indian state of West Bengal and the country of Bangladesh. This region has a rich history of contributions to mathematics, science, and culture.
"Brazilian mathematicians" refers to mathematicians from Brazil or those who have had a significant impact on mathematics while being associated with Brazil in some way. Brazil has a rich history in mathematics, with several notable mathematicians contributing to various fields such as algebra, topology, number theory, and applied mathematics.
The term "Maldivian mathematicians" refers to mathematicians from the Maldives or those who study mathematics within the context of Maldivian culture and history. The Maldives, an island nation in the Indian Ocean, may not have a widely recognized historical contribution to mathematics on a global scale like other countries, but there are certainly individuals and scholars who contribute to the field, whether through education, research, or application in various sectors.
The term "Flemish mathematicians" generally refers to mathematicians from Flanders, a region in Belgium. Flanders has a rich history of contributions to mathematics, science, and education, particularly during the Renaissance and the centuries that followed.

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.
