J. Robert Oppenheimer was an American theoretical physicist who is best known for his role as the scientific director of the Manhattan Project, the World War II endeavor that developed the first nuclear weapons. Born on April 22, 1904, in New York City, he was a prominent figure in the field of quantum mechanics and made significant contributions to theoretical physics.
Individual graphs, in a general context, typically refer to graphical representations of data or information for single sets of variables or individual data points. Here are some relevant aspects: 1. **Single Variable Representation**: Individual graphs often display data related to a single variable, showcasing trends, distributions, or patterns. Common types include line graphs, bar charts, and pie charts. 2. **Statistical Analysis**: In statistics, individual graphs might be used to represent individual data points or cases within a dataset.
Mathematical analysis is a branch of mathematics that focuses on the study of limits, functions, derivatives, integrals, sequences, and series, as well as the properties of real and complex numbers. It provides the foundational framework for understanding continuous change and is widely applicable across various fields of mathematics and science.
Functional equations are equations in which the unknowns are functions rather than simple variables. These equations relate the values of a function at different points in its domain and often involve operations on those functions, such as addition, multiplication, or composition. They are used to determine the forms of functions that satisfy certain conditions.
In the context of Wikipedia and similar collaborative knowledge platforms, "stubs" refer to short or incomplete articles that provide only a basic overview of a topic but lack comprehensive detail or coverage. Mathematical analysis stubs are articles related to the field of mathematical analysis that may not contain extensive information or may need additional contributions to improve their content. Mathematical analysis itself is a branch of mathematics that deals with limits, continuity, differentiation, integration, sequences, series, and functions.
Unsolvable puzzles are problems or puzzles that cannot be solved within the given constraints, or do not have a solution at all. These can arise in various contexts, including mathematics, logic, computer science, and recreational puzzles. Here are a few examples: 1. **Mathematical Puzzles**: Some mathematical problems are proven to be unsolvable.

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
