Diodorus Cronus was a prominent ancient Greek philosopher, typically associated with the Megarian school of philosophy. He lived around the 4th century BCE and is known primarily for his work in logic, particularly his contributions to the theories of modality and the nature of time. Diodorus is often remembered for his "master argument," which is a formal argument against the possibility of future contingents—that is, statements about future events that are not yet determined.
Chrysippus was an ancient Greek philosopher who lived from approximately 280 to 206 BCE. He is best known as a prominent figure in the Stoic school of philosophy.

Xenagoras was an ancient Greek geometer, known primarily for his work on geometry. He lived around the 4th century BCE and is sometimes associated with students or followers of Plato. His contributions are not as extensively documented as those of other prominent mathematicians, and much of what is known about him comes from later references.
Theodosius of Bithynia was an ancient Greek mathematician and astronomer who lived around the 2nd century BCE, during the Hellenistic period. He is best known for his contributions to the field of astronomy, particularly for his work in the development of star catalogs.

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.
