The Parrot's Theorem is a humorous and informal mathematical theorem that originated in a cartoon by mathematician and author Paul Erdős. The essence of the theorem is that if a parrot mimics the phrase "I am a math genius," then at least one person in the room will believe it. While not a formal theorem in the traditional sense, it serves to illustrate ideas about belief, perception, and the influence of authority or charisma in discussions, particularly in mathematics and academia.
A wireless mesh network is a type of network topology where multiple wireless devices (nodes) work together to create a flexible and self-organizing network. Unlike traditional networks that rely on a central router or access point, a mesh network allows each node to communicate with one another directly, extending the network's range and reliability.

"Topics" is one of Aristotle's works in which he addresses the nature of dialectical reasoning and argumentation. In this text, Aristotle explores how to construct and evaluate arguments, focusing particularly on how to engage in reasoning about likely or probable conclusions rather than certain truths. The main purpose of "Topics" is to provide a systematic method for argumentation, particularly in the context of informal logic and debate.
A finite potential well is a concept in quantum mechanics that describes a potential energy region in which a particle can exist with energy levels that are quantized. Unlike an infinite potential well, where the potential energy is infinitely high outside a certain region, a finite potential well has a finite depth and finite width.
The Hong–Ou–Mandel (HOM) effect is a phenomenon in quantum optics that describes the interference of indistinguishable single photons. It was first observed by physicists Claude Hong, Ming Wu Ou, and Leonard Mandel in 1987. The effect illustrates the unique behaviors of quantum particles, specifically bosons, such as photons.
Quantum suicide and immortality are thought experiments related to the interpretation of quantum mechanics, particularly the many-worlds interpretation (MWI). These concepts explore the implications of quantum mechanics on concepts of life, death, and consciousness. ### Quantum Suicide The thought experiment of quantum suicide was devised by physicist David Deutsch and is typically framed as a scenario involving an observer and a quantum event with two outcomes.

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.
