The Gaussian gravitational constant, often denoted as \( k \), is a constant used in the field of celestial mechanics and gravitational calculations, particularly in the context of the Gaussian gravitational constant equations. It is defined in terms of the gravitational constant \( G \) and is primarily used in the analysis of orbits and related calculations.
"What Is This Thing Called Science?" is a book by the philosopher of science Alan Chalmers, first published in 1976. The book serves as an introduction to the philosophy of science, exploring various themes related to scientific inquiry and the nature of scientific knowledge. Chalmers discusses key concepts such as the scientific method, the distinction between science and non-science, the role of experiments, and the nature of scientific theories.
Instrumental magnitude refers to a measurement of the brightness of an astronomical object as recorded by a specific instrument, typically an astronomical telescope or photometer. This measurement is usually made without any corrections for atmospheric conditions, the object's distance, or intrinsic brightness. Instrumental magnitude is an important concept in observational astronomy since it provides the raw data for further analysis.

TopoFlight is known for its ability to handle large datasets, integrating various types of geospatial data from different sources, including LiDAR and aerial imagery.
The inductive effect refers to the permanent shifting of electron density in a molecule due to the electronegativity differences between atoms within that molecule. It involves the polarization of sigma (σ) bonds, which arises when one atom in a bond pulls the shared electrons towards itself more than the other atom does, creating a dipole moment. This shifting of electron density can influence the reactivity and stability of chemical species.
The Möbius-Hückel concept is a theoretical framework used in organic chemistry and theoretical chemistry to understand the properties and stability of certain cyclic compounds, particularly those with conjugated π-electron systems. This concept revolves around the idea of electron delocalization and the geometry of π-systems, influenced by the principles of molecular orbital theory.
Madhava's correction term refers to a specific term that arises in the context of the series expansion of certain mathematical functions, especially in the calculation of \(\pi\). The term is associated with Indian mathematician Madhava of Sangamagrama, who lived in the 14th century and is often credited with developing early ideas of calculus and infinite series.
Lanthanum gallium silicate (LaGaSiO₇) is a type of silicate material that is a part of the family of lanthanide-based compounds. It is notably used in various applications, primarily due to its beneficial properties such as high stability, thermal resistance, and potential as a semiconductor.
Exozodiacal dust refers to a component of dust found in the vicinity of other stars, particularly within the habitable zones of those stars. It is analogous to the zodiacal light observed in our own solar system, which is the sunlight scattered by dust particles that are primarily located in the plane of the solar system, typically originating from comets and asteroid collisions.
Plastic welding is a process used to join plastic materials together by melting the surfaces and allowing them to fuse as they cool. This technique is widely employed in various industries, including automotive, aerospace, packaging, and manufacturing, to create strong, durable bonds between plastic components.
Acrylonitrile butadiene styrene (ABS) is a thermoplastic polymer commonly used in various applications due to its strength, toughness, and ability to be easily molded. It is a copolymer made from three monomers: 1. **Acrylonitrile** - This component provides chemical resistance and thermal stability. 2. **Butadiene** - This contributes to the impact resistance and toughness of the material, making it less brittle.
Merrifield resin is a type of polymer resin commonly used as a solid support in solid-phase peptide synthesis (SPPS). It was developed by the chemist Robert Merrifield, who won the Nobel Prize in Chemistry in 1984 for his work on this method. The resin is typically made from polystyrene or a polystyrene-divinylbenzene copolymer and is functionalized with an appropriate linker that allows for the attachment of the growing peptide chain.
Wood-plastic composite (WPC) is a material made from a combination of wood fibers or wood flour and thermoplastics, such as polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC). This composite combines the natural aesthetic and structural properties of wood with the durability and versatility of plastics.
As of my last knowledge update in October 2021, Mariusz Lemańczyk does not appear to be a widely recognized public figure, organization, or concept. It is possible that he is a private individual or has gained recognition in a specific field or area after that date.
Bernard Whitman is not widely recognized as a public figure in prominent historical, cultural, or political narratives. If you are referring to a specific individual named Bernard Whitman, additional context would be helpful. It's possible he might be a local figure, a professional in a particular field, or perhaps a character in a work of fiction.

He serves as the CEO of Ipsos Public Affairs, a global market research and polling firm. Bricker is recognized for his expertise in interpreting trends in public attitudes and behaviors, especially in relation to Canadian politics. In addition to his role at Ipsos, he has co-authored books and articles discussing voter behavior and the changing dynamics of Canadian society.
As of my last update in October 2023, Nick Langworthy is a Republican politician from New York. He serves as the Chair of the New York State Republican Party. Langworthy was previously a member of the New York State Assembly, representing the 142nd district, which includes parts of Erie County. He has been an active figure in New York politics, focusing on issues pertinent to his constituents and the state Republican Party.
The medial rhombic triacontahedron is a type of Archimedean solid that can be characterized as a convex polyhedron. It is derived from a rhombic triacontahedron, which has 30 rhombic faces, by truncating (or cutting off) the vertices of the original solid. This truncation results in the creation of hexagonal faces at the vertices that were removed.
The small icosicosidodecahedron is a convex Archimedean solid characterized by its unique arrangement of faces, vertices, and edges. Specifically, it is composed of 62 faces: 20 regular triangles, 30 squares, and 12 regular pentagons. It has a total of 120 edges and 60 vertices.
Bioplastic refers to a type of plastic that is either made from renewable biomass sources, such as plant materials, or is designed to biodegrade more easily than traditional plastics. There are two main categories of bioplastics: 1. **Bio-based Plastics**: These are primarily made from renewable resources like starch, cellulose, or polylactic acid (PLA) derived from corn or sugarcane.

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.
