Glottochronology is a method used in historical linguistics to estimate the time of divergence between languages based on the rate of change of their vocabulary. The technique operates on the premise that languages evolve and that this evolution can be quantified in terms of vocabulary replacement over time.
A **covert channel** is a method used to transfer information in a way that violates the system's security policy. It allows communication between different processes or systems that isn't intended or permitted by the security mechanisms in place. Covert channels can be classified into two main types: 1. **Storage Channels**: These operate by altering a storage location that is accessible to both the sender and the receiver.
The Journal of Statistical Software (JSS) is a peer-reviewed academic journal that publishes articles related to statistical software and computational methods in statistics. Established in 1996, it focuses on the development, implementation, and applications of statistical software, providing a platform for researchers and practitioners to share their work.

The Le Bel–Van 't Hoff rule, also known as the Le Bel-Van 't Hoff rule of stereochemistry, relates to the spatial arrangement of molecules and their optical activity. Specifically, it provides insight into the relationship between the number of stereocenters in a molecule and the number of possible stereoisomers.
The Chapman-Kolmogorov equation is a fundamental relation in the field of stochastic processes, particularly in the study of Markov processes. It describes how transition probabilities between states in a Markov chain can be related over time.
Pakistani string theorists refer to physicists from Pakistan who study string theory, a theoretical framework in physics that attempts to reconcile general relativity and quantum mechanics. String theory posits that the fundamental constituents of the universe are not point-like particles, but rather one-dimensional objects called strings, which can vibrate in different ways. The specific vibrational modes of these strings are thought to correspond to different particles. Several Pakistani scientists and researchers have contributed to the field of theoretical physics, including string theory.
Douglas C. Rees is a prominent American biochemist known for his research in the fields of structural biology, metal ion biochemistry, and enzymology. He has made significant contributions to our understanding of metalloenzymes, which are enzymes that contain metal ions as essential cofactors. His research often focuses on the mechanisms by which these enzymes catalyze various biochemical reactions and their biological importance.
Amigurumi is a Japanese term that refers to the art of knitting or crocheting small, stuffed yarn creatures. The word comes from combining "ami," which means knitted or crocheted, and "nuigurumi," which means stuffed toy. Amigurumi creations can range from animals to people and various objects, often characterized by their cute and whimsical designs. Typically made using crochet techniques, amigurumi is usually worked in the round and involves making individual pieces that are sewn together.
A teddy bear is a soft, stuffed toy in the shape of a bear, commonly used as a children's toy or comfort object. Typically made from plush fabric and filled with materials like polyester fiber or cotton, teddy bears come in various sizes, colors, and designs. They often have button or embroidered eyes and a stitched nose and mouth. The teddy bear has become an iconic symbol of childhood and comfort, often associated with warmth, love, and friendship.
Jerry Nelson was a prominent American astronomer and astrophysicist best known for his work in the field of optical and infrared astronomy. He is particularly renowned for his pioneering contributions to the development of large telescope technology. Nelson was instrumental in the design and construction of the Keck Observatory's twin 10-meter telescopes in Hawaii, which are among the largest and most powerful optical telescopes in the world.
Interfacial rheology is the study of the mechanical properties and behavior of interfaces, typically between two immiscible phases, such as liquids, gases, or solids. This field focuses on how forces and deformations affect the interface and how the interfacial properties influence the overall behavior of the materials involved.
A laser line level is a type of leveling tool that projects a straight line of laser light onto a surface, allowing for precise alignment and leveling of various construction and installation tasks. It is commonly used in construction, carpentry, and interior design for both horizontal and vertical alignment.
In surveying, a "pole" is an older unit of measure that is equivalent to 16.5 feet, or 5.5 yards. It is also referred to as a "rod" or "perch." This unit was historically used in land surveying and can be encountered in real estate, agricultural measurement, and mapping. The pole is part of a chain measurement system, where a chain equals 66 feet, and there are 4 poles in one chain.
The Global Alliance for EcoMobility is an international network that promotes sustainable and eco-friendly urban mobility solutions. Launched in 2015, the alliance aims to foster collaboration among city leaders, policymakers, urban planners, and various stakeholders to advance sustainable transportation practices.

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.
