Sima is a term used in geology to describe the layer of the Earth's crust that is rich in silicate and magnesium minerals. It is an abbreviation derived from "silicate" and "magnesium." Sima primarily constitutes the oceanic crust and is generally found beneath the oceanic lithosphere, where it is composed mostly of basalt and gabbro. In contrast to sima, a term "sial" refers to the continental crust, which is rich in silica and aluminum.

"Sun stubs" is not a widely recognized term in most contexts. However, it may refer to "stubs" in programming or computing in relation to "Sun Microsystems," a company known for its hardware and software products, particularly in the areas of servers and workstations. In programming, a "stub" can refer to a piece of code used to stand in for some other functionality.
Heliophysics is the scientific study of the Sun and its interactions with the solar system, particularly the Earth and other celestial bodies. It encompasses a range of topics, including solar physics, space weather, and the effects of solar radiation and magnetic fields on planetary atmospheres and climates.
"Growling" can refer to different contexts depending on the setting. Here are a few common interpretations: 1. **Animal Behavior**: In the animal kingdom, particularly among canines like dogs or wolves, growling is a vocalization that can indicate a range of emotions, including fear, aggression, or a warning to stay away. It serves as a communication tool among animals.
Coda wave interferometry is a seismic analysis technique used to investigate the properties of the Earth's interior and to monitor changes in subsurface structures. It leverages the analysis of coda waves, which are the later arriving waves in a seismic signal that follow the direct waves (such as P and S waves) after an earthquake or artificial seismic event. Coda waves are formed by multiple scattering of seismic waves within and around the seismic source region.
The term "Horn analyzer" typically refers to tools or algorithms used to analyze and solve problems related to Horn clauses in logic programming and database theory. Horn clauses are a specific type of logical expression used primarily in propositional logic and predicate logic, characterized by having at most one positive literal. They are named after the mathematician Alfred Horn.
SplitFire spark plugs are a type of aftermarket spark plug designed to improve engine performance, fuel efficiency, and reduce emissions compared to standard spark plugs. The distinguishing feature of SplitFire spark plugs is their unique design, which includes dual ground electrodes. This configuration allows for multiple spark discharge points, which can enhance ignition efficiency and combustion. The design aims to create a better flame kernel, leading to more complete combustion of the air-fuel mixture in the engine's combustion chamber.
In fiction, "stasis" refers to a state of equilibrium or balance in a storyline, where characters and their circumstances are relatively unchanging or static. This concept is often used to set the stage for a story, providing a baseline for how things are before a conflict or significant change disrupts the status quo.

2022-10-14: stopped being able to connect to Ubuntu 22.04. Was trying to do a UART video demo, connected USB, disconnected, connected, disconnected several times on different filming attempts. Was working some of the time, Ubuntu did recognize it, I even saw UART output for sure, but was a bit unstable. But then at one point it just stopped getting recognized by Ubuntu 100% of the time. The board is still being powered by USB, and the previously flashed program still runs, but nothing showed on sudo dmesg -w at all, and I can't reprogram it!
A day later, managed to get tit to connect once more with a different cable, but just once!

Nuclear blues by Ciro Santilli 40 Updated 2025-10-14
Term invented by Ciro Santilli, it refers to Richard Feynman, after helping to build the atomic bomb:
And I would go along and I would see people building a bridge, or they'd be making a new road, and I thought, they're crazy, they just don't understand, they don't understand. Why are they making new things? It's so useless.
MINOS+ is a software tool developed for multi-objective optimization problems. Specifically, it is an extension of the original MINOS solver, which stands for "Modified Interior-Point Method for Nonlinear Programming." MINOS+ is designed to handle problems that can involve multiple conflicting objectives, allowing users to find a set of optimal solutions known as the Pareto front.
Recycling antimatter is not a widely established concept or technology, as antimatter is a rare and expensive substance currently produced only in small quantities in particle accelerators and laboratories. Antimatter consists of particles that have the same mass as regular matter but opposite charge and quantum spin properties. For example, the antimatter counterpart of an electron is called a positron, which has a positive charge.

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.
    Figure 2.
    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
