Sky Global was a messaging service that provided secure, encrypted communication primarily known for its cryptocurrency-related activities and privacy features. As of my last update in October 2023, law enforcement agencies conducted actions against Sky Global in early 2022, culminating in the shutdown of its services. The shutdown involved the seizure of servers and other infrastructure used by the company, which was implicated in providing a platform for criminal activities, including drug trafficking and other illegal enterprises, due to its encryption and privacy-enhancing qualities.
The Borell–Brascamp–Lieb (BBL) inequality is a result in the field of measure theory and functional analysis, particularly in the study of convex functions and their relationships to volume measures and integrals. It generalizes several well-known inequalities, including the Brunn-Minkowski inequality. The inequality provides a way to compare the integrals of convex functions with respect to measures that are related through certain kinds of convex combinations.
A spoil tip, also known as a spoil heap, waste tip, or overburden dump, refers to a pile or mound of waste material that is generated during the extraction of minerals or other materials from the earth. This material typically consists of rock, soil, and other debris that is removed during mining processes or construction activities. Spoil tips are often found in areas where mining operations take place, such as coal mines, quarries, or other mineral extraction sites.

KCNK1, also known as the potassium channel subfamily K member 1, is a gene that encodes a protein belonging to the two-pore domain potassium channel family. These channels are crucial for controlling the flow of potassium ions across cell membranes, which is essential for various physiological processes, including maintaining resting membrane potential, regulating cellular excitability, and influencing the heart's electrical activity.
A Schottky defect is a type of point defect that occurs in ionic crystals. It involves the simultaneous vacancy of an anion and a cation in the crystal lattice, maintaining the overall charge neutrality of the material. Essentially, a Schottky defect is characterized by the absence of one positive ion (cation) and one negative ion (anion) from their respective lattice sites. This defect can influence the properties of the material, such as its density, ionic conductivity, and electrical properties.
A buoyancy engine is a theoretical concept often discussed in the context of alternative energy or perpetual motion machines. The idea revolves around using differences in buoyancy (the upward force that a fluid exerts on an object submerged in it) to create a system that can generate work or energy. The fundamental principle behind buoyancy is that objects denser than the fluid they are in sink, while less dense objects float.
Supercritical liquid-gas boundaries refer to the phase boundary that exists in a substance when it is subjected to conditions above its critical temperature and critical pressure. At these conditions, the substance enters a supercritical state, where distinct liquid and gas phases do not occur. ### Key Concepts: 1. **Critical Point**: This is the specific point on a phase diagram for a substance where the temperature and pressure are so high that the liquid and gas phases become indistinguishable.
Geomagnetic jerk refers to a sudden change or discontinuity in the Earth's magnetic field over a relatively short period of time, typically on the order of a few years. This phenomenon is often observed in the secular variation of the Earth's magnetic field, which is its gradual changes over time. Geomagnetic jerks can manifest as abrupt changes in the strength or direction of the magnetic field.

Atomic diffusion refers to the process by which atoms or molecules move from regions of higher concentration to regions of lower concentration within a material. This movement can occur in various phases, such as solids, liquids, and gases, and it is a fundamental mechanism that influences numerous physical and chemical processes. In the context of solid materials, atomic diffusion can occur due to thermal vibrations of atoms within a lattice structure, allowing them to hop from one lattice site to another.
"Former bodies of water" refers to areas that were once filled with water but are now dry or have undergone significant changes leading to their current state. This term can apply to various geological features, including: 1. **Dry Lake Beds (Playas)**: Flat areas that were once lakes but have dried up, often leaving behind salt flats or sediment.
Ozone cracking, also known as ozone stress cracking or ozone-induced cracking, is a type of deterioration that affects certain materials, particularly elastic polymers like rubber. It occurs when rubber materials are exposed to ozone gas, typically in the atmosphere, especially at higher altitudes or in industrial environments where ozone levels may be elevated. Ozone molecules can penetrate the surface of the rubber material and react with the polymer chains, leading to the formation of cracks.
The Sir Edmund Whittaker Memorial Prize is an award established in memory of Sir Edmund Whittaker, a distinguished mathematician known for his contributions to various fields within mathematics.

They may honor research, innovation, teaching, and other significant accomplishments related to geophysical sciences.
Mathematical Q models generally refer to a specific type of modeling used in diverse fields such as economics, finance, and statistics. However, the term "Q models" can have different interpretations based on the context in which it's used. Here are a few common interpretations: 1. **Investment Models (Q Theory)**: In economics, particularly in the context of investment theory, the term "Q" is often associated with Tobin's Q.
The Vine–Matthews–Morley hypothesis, proposed in the 1960s by geologists Frederick J. Vine, Dr. David H. Matthews, and Dr. Robert A. Morley, is a significant concept in the field of plate tectonics and oceanography. It provides an explanation for the symmetrical patterns of magnetic stripes found on the ocean floor, which are linked to the process of seafloor spreading.
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.

Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
