Grepping the 2013 DNS Census first by overused CGI comms subdomains secure. and ssl. leaves 200k lines. Grepping for the overused "news" led to hits:
  • secure.worldnewsandent.com,2012-02-13T21:28:15,208.254.40.117
  • ssl.beyondnetworknews.com,2012-02-13T20:10:13,66.104.175.40
Also tried but failed:
OK, after the initial successes in secure., we went a bit more data intensive:
New results: only one...

After 2013 DNS Census virtual host cleanup heuristic keyword searches we later understood why there were so few hits here: the 2013 DNS Census didn't capture the secure. subdomains of many domains it had for some reason. Shame, because if it had, this method would have yielded many more results.
Mathematical proofs are logical arguments that demonstrate the truth or validity of a mathematical statement or theorem. A proof provides an explanation of why a particular statement is true based on axioms (fundamental truths accepted without proof), previously established theorems, and logical reasoning. Key features of mathematical proofs include: 1. **Logical Structure**: A proof is constructed using a clear logical framework, often consisting of statements and arguments that follow a structured approach.
Mathematical terminology refers to the specific language, symbols, and vocabulary used in the field of mathematics. This terminology helps convey concepts, methods, and relationships in a precise and standardized way. Here are some key aspects of mathematical terminology: 1. **Definitions**: Precise descriptions of mathematical concepts, such as "a prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
In astronomy, "concepts" refer to the fundamental ideas and principles that help us understand the universe and its various phenomena. Here are some key concepts in astronomy: 1. **Celestial Bodies**: This includes stars, planets, moons, asteroids, comets, galaxies, nebulae, and black holes. Each has distinct characteristics and behaviors. 2. **Orbits**: The motion of celestial bodies as they travel in elliptical paths around larger bodies due to gravitational forces.
Physical systems refer to any collection of physical entities that interact according to the laws of physics. These systems can consist of matter, energy, and various physical interactions, and they can be as simple as a single particle or as complex as a galaxy. Physical systems can be studied across various fields of science, including physics, engineering, and chemistry. Physical systems can be classified in several ways: 1. **Open vs.
Unsolved problems in physics refer to questions and phenomena that remain unexplained despite extensive research and experimentation. These problems often span various fields of physics, including theoretical physics, particle physics, cosmology, and condensed matter physics. Here are some notable examples of unsolved problems in physics: 1. **Quantum Gravity**: One of the major challenges in theoretical physics is reconciling general relativity, which describes gravitation on a large scale, with quantum mechanics, which governs subatomic particles.

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
