The List of Kreutz Sungrazers refers to a catalog of comets that belong to the Kreutz family, which are known for their extremely close approaches to the Sun, often resulting in their disintegration. These comets are characterized by their high velocities and their characteristic orbits that take them very close to the Sun, typically within a few thousand kilometers of the solar surface.
The List of Mercury-crossing minor planets consists of minor planets (or asteroids) whose orbits cross the orbit of Mercury, the innermost planet of our solar system. These objects are categorized based on their proximity to the Sun and their orbital characteristics. Mercury-crossing asteroids are of particular interest to astronomers because they can provide insights into the dynamic processes of the inner solar system.

The term "Berlin Circle" typically refers to a philosophical movement or group of philosophers and scientists in the early to mid-20th century who were associated with the Berlin School of Logical Empiricism. This group was influential in the development of logical positivism and scientific philosophy, focusing on the relationships between language, knowledge, and empirical verification. The Berlin Circle sought to promote a scientific worldview that emphasized clarity, logical coherence, and empirical validation.
A "coordinative definition" typically refers to a type of definition where a concept is defined by establishing its relationship to other concepts or terms that are considered equivalent or closely related. This method is often used in academic and philosophical contexts to clarify meanings and ensure that the terminology is understood in relation to similar concepts. In essence, a coordinative definition does not just provide a description of a term but also situates it within a network of related terms, helping to create a more comprehensive understanding.
Otto Neurath (1882–1945) was an Austrian philosopher, sociologist, and graphic designer, known for his contributions to logical positivism and the development of a theory of social science. He was a prominent member of the Vienna Circle, a group of philosophers and scientists that included figures like Moritz Schlick and Rudolf Carnap, who were influential in the early 20th century.
"Two Dogmas of Empiricism" is a philosophical work by Willard Van Orman Quine, published in 1951. In this influential paper, Quine critiques two central tenets of empiricist philosophy, which are often considered foundational to the philosophy of science and knowledge. 1. **The First Dogma**: This is the belief in the analytic-synthetic distinction. Analytic statements are those that are true by virtue of their meanings (e.g.
M. C. Escher was a Dutch graphic artist known for his mathematically inspired works featuring impossible constructions, explorations of infinity, and tessellations. His distinctive style has influenced various media, including video games.
M. C. Escher, a Dutch graphic artist known for his fascinating and mathematically inspired works, created a variety of artwork that explores concepts of infinity, symmetry, and perspective. His works often feature impossible constructions, tessellations, and intricate patterns that challenge viewers' perceptions of reality.
Mechanical musical instruments are devices that produce music through physical mechanisms, rather than electronic means. These instruments typically use gears, levers, wheels, and other mechanical parts to generate sound. They are often designed to play pre-determined melodies or tunes and can be found in a variety of forms, from simple to complex.
Woodworking machines are tools and equipment designed to help in the processing, shaping, and finishing of wood to create various products, such as furniture, cabinetry, and decorative items. These machines can range from simple hand-operated tools to complex automated systems. Here are some common types of woodworking machines: 1. **Table Saw**: A saw with a circular blade mounted on an arbor, used for making straight cuts in wood.
"Laying" can refer to several different concepts depending on the context. Here are a few common meanings: 1. **Physical Action**: It often refers to the act of placing something down in a horizontal position. For example, "laying down a book." 2. **Reproductive Context**: In the context of animals, particularly birds, "laying" refers to the act of producing or depositing eggs.
A machine tool is a type of machinery used for shaping or machining metal and other materials by cutting, grinding, shearing, or other forms of deformation. Machine tools are essential in manufacturing and are used in a variety of processes, including drilling, turning, milling, and shaping. They can be operated manually or automatically (CNC machine tools). Machine tools typically consist of a tool holder, a workpiece holder, and some form of drive mechanism.
The machine industry, often referred to as the machinery or manufacturing sector, encompasses the design, production, and maintenance of machines and equipment used in various processes, including industrial, commercial, and consumer applications. It plays a crucial role in the overall manufacturing landscape and includes a wide range of activities and sub-industries.
Bioceramics are a class of ceramic materials that are specifically designed for use in biological applications, particularly in the fields of medicine and dentistry. These materials are biocompatible, meaning they can interact with biological systems without causing an adverse effect. Bioceramics are often used in the repair or replacement of bone and dental tissue due to their favorable properties, such as mechanical strength, chemical stability, and the ability to promote bone growth.
A tablet press is a piece of machinery used in the pharmaceutical industry and other sectors to compress powder into tablets. This process, known as tablet compression or tableting, involves applying high pressure to a mixture of active pharmaceutical ingredients (APIs) and excipients (inactive ingredients that aid in the manufacturing process and improve the tablet's performance) to form solid tablets.
In the context of engines, particularly internal combustion engines, a "stall" refers to a condition where the engine suddenly loses power and stops running, typically due to a failure of the engine to maintain ignition or combustion. This can occur for various reasons, including: 1. **Fuel Starvation**: Insufficient fuel supply to the engine can cause it to stall.

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.
