Polish set theory, often referred to in the context of Polish spaces, is a concept in set theory and topology that involves certain kinds of topological spaces known as Polish spaces. A Polish space is a separable completely metrizable topological space. This means that the space can be endowed with a metric (a way of measuring distances) such that it is both complete (every Cauchy sequence converges) and separable (contains a countable dense subset).
Paul Cohen can refer to a few notable individuals, but one of the most prominent is Paul Cohen (1934–2007), an American mathematician known for his work in set theory and logic. He is particularly famous for developing the technique of forcing, which he used to prove the independence of the continuum hypothesis and the axiom of choice from Zermelo-Fraenkel set theory. This work was groundbreaking and significantly advanced the field of mathematical logic.
SUPS can refer to different terms depending on the context, but one common interpretation is "Standardized Universal Product Specifications." This term is often used in industries like retail and manufacturing to denote a standardized set of specifications that help in identifying and describing products. Another possible meaning could be "Supplemental Nutritional Products" in the context of nutrition and health.
Embryo drawing typically refers to the artistic or scientific representation of embryos at various stages of development. These drawings can serve multiple purposes, including educational tools in biology and art, illustrations for medical literature, or components in a broader exploration of developmental biology.

GW190521 is the designation for a gravitational wave event detected by the LIGO and Virgo observatories on May 21, 2019. This event is particularly significant because it was caused by the merger of two black holes, resulting in the formation of a more massive black hole. The detection of GW190521 provided important insights into the population of black holes in the universe.

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.
