The study of mathematicians can be categorized by their countries of origin or the nations they were associated with during their careers. Here’s a brief overview of some notable mathematicians by former country: ### Ancient Greece - **Euclid**: Often referred to as the "father of geometry." - **Pythagoras**: Known for the Pythagorean theorem. - **Archimedes**: Made significant contributions to geometry, calculus, and the understanding of physical laws.
"Moldovan mathematicians" generally refers to mathematicians from Moldova, a country in Eastern Europe. While the nation may be small, it has produced a number of notable mathematicians who have contributed to various fields of mathematics. The country has a history of engagement in mathematics education and research, especially during the Soviet era when many Moldovan mathematicians were active in academia and participated in international mathematical communities.
New Zealand has a rich history of contributions to mathematics and is home to several notable mathematicians. Some prominent New Zealand mathematicians include: 1. **A. W. (Alex) W. Pycroft** - Known for his work in combinatorial geometry and mathematics education. 2. **Marilyn Anne S. Hawkes** - Noted for her research in algebra and group theory.
Robert McMahan might refer to several individuals, as it is not an uncommon name. Without more specific context, it's difficult to identify exactly which Robert McMahan you are referring to. If you have a particular field (such as academia, business, arts, etc.
South African mathematicians have made significant contributions to various fields of mathematics, both historically and in contemporary research. They include prominent figures who have excelled in theoretical mathematics, applied mathematics, mathematical physics, statistics, and more. Some notable South African mathematicians include: 1. **George P. E. M. Van der Linde** - Known for his work in the field of algebra.
The term "Spanish mathematicians" refers to individuals from Spain or of Spanish descent who have made significant contributions to the field of mathematics. Throughout history, Spain has produced several notable mathematicians who have influenced various areas of mathematics. Here are a few prominent Spanish mathematicians: 1. **Jerónimo de la Madre de Dios** (1548–1614) - Known for his work in algebra and for publishing several important mathematical texts during the Renaissance.
Tajikistani mathematicians are mathematicians from Tajikistan or those who have roots in Tajik culture and heritage. Tajikistan, a country in Central Asia, has a rich history of intellectual contributions, including in the field of mathematics. Throughout history, mathematicians and scholars from the region have made notable contributions to various mathematical disciplines.
Tunisian mathematicians have made significant contributions to various fields of mathematics, and Tunisia has a rich intellectual tradition in mathematics. Some notable aspects include: 1. **Historical Contributions**: Historically, the region has been influenced by the mathematics of ancient civilizations, including the Greeks and Arabs.

JCVI-syn3B by Ciro Santilli 40 Updated 2025-07-16

CVI-syn3B strains differ from JCVI-syn3.0 by the presence of 19 additional non-essential genes that result in a more easily manipulated cell. JCVI-syn3B additionally includes a dual loxP landing pad that enables easy Cre recombinase mediated insertion of genes
It is also interesting to see how they are interested in co-culture with HeLa cells, presumably to enable infectious bacterial disease studies.
At biology.indiana.edu/news-events/news/2023/lennon-minimal-cells.html (2023) they let it re-evove to it it would regain some fitness, and it did.
Amoeba by Ciro Santilli 40 Updated 2025-07-16
This group is a mess.
But one thing you should really know, as often mentioned in Power, Sex, Suicide by Nick Lane (2006): they are all eukaryotes.
Because prokaryotes are fundamentally unable to do phagocytosis, because they have a rigid cell wall. Changing cell shape at will requires a cytoskeleton.
Cloaca by Ciro Santilli 40 Updated 2025-07-16
A single hole that is used for shit, pee and fucking. Amazing.
Chordate by Ciro Santilli 40 Updated 2025-07-16
Chordate is a sad clade.
You read the name and think: hmm, neural cords!
But then you see that his is one of its members:
Yup. That's your cousin. And it's a much closer cousin than something like arthropods, which at least have heads eyes and legs like you.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
