A weld neck flange is a type of flange used to connect pipes, valves, pumps, and other equipment in a piping system. Here are some key characteristics and features of weld neck flanges: 1. **Design**: Weld neck flanges have a long neck or taper that facilitates a smooth transition between the flange and the pipe. This design helps to reduce the risk of stress concentration and improves the flow characteristics of the piping system.
TOI-1338 is a binary star system located approximately 330 light-years away from Earth. It is known for hosting two exoplanets, TOI-1338 b and TOI-1338 c. The system was identified and studied through NASA's Transiting Exoplanet Survey Satellite (TESS) mission, which is designed to discover and characterize exoplanets by observing the light curves of stars for transits—periodic dimming caused by planets passing in front of them.
TOI-700 d is an exoplanet located in the habitable zone of its star, TOI-700, which is situated about 100 light-years away from Earth in the constellation Dorado. It was discovered using data from the Transiting Exoplanet Survey Satellite (TESS), a NASA mission designed to identify and characterize exoplanets. TOI-700 d is particularly interesting because it is roughly Earth-sized, with a mass and radius close to those of our own planet.
An "extraterrestrial vortex" is not a widely recognized scientific term, but it may refer to concepts related to vortex phenomena that could occur in extraterrestrial environments, such as other planets or celestial bodies. In general, a vortex is a region in a fluid where the flow revolves around an axis line, which can occur in atmospheres or bodies of water.
Saturn's hexagon is a fascinating atmospheric feature located at the planet's north pole. It is characterized by its unique hexagonal shape, which measures approximately 29,000 kilometers (about 18,000 miles) across. This geometric pattern is formed by a type of rotating storm that creates stable, long-lasting cloud formations. The hexagon has been observed and studied primarily by NASA's Voyager and Cassini spacecraft.
Helion Energy is a company focused on developing advanced nuclear fusion technology as a means of generating clean energy. Founded in 2013 and based in Redmond, Washington, Helion aims to harness nuclear fusion—the process that powers the sun—by creating conditions favorable for fusion reactions to occur. The company's approach involves using magnetic confinement to achieve the necessary temperatures and pressures for nuclear fusion.
As of my last update in October 2023, Kamil Hornoch does not appear to be a widely known public figure, concept, or term. It's possible that he could be a private individual or someone who has become notable after my last update.
A list of brown dwarfs typically includes various known brown dwarfs identified by their spectral types, designations, and other characteristics. Brown dwarfs are substellar objects that are larger than planets but not massive enough to sustain hydrogen fusion at their cores, which distinguishes them from stars. The spectral types of brown dwarfs range from L to T and Y, indicating their temperature and composition.
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.
A technology roadmap is a strategic planning tool that outlines the vision, goals, and roadmap for implementing technology within an organization or a specific project. It serves as a guide for aligning technology initiatives with business objectives, identifying the necessary resources, and establishing timelines for technology development and deployment. Key components of a technology roadmap include: 1. **Vision and Goals**: A clear articulation of the long-term vision for technology and specific goals that the organization aims to achieve.
The term "proposals" can refer to different things depending on the context. Here are some common interpretations: 1. **Business Proposals**: These are formal documents submitted to persuade an organization or individual to accept a service or product. Business proposals typically include background information, project objectives, methodology, budget estimates, and timelines. 2. **Research Proposals**: In academia, a research proposal outlines a plan for a research project.
Daylight redirecting film (DRF) is a type of architectural film designed to enhance the distribution of natural light within interior spaces. This film is typically applied to windows or skylights and functions by redirecting sunlight deeper into a building, thereby improving daylight penetration and reducing the need for artificial lighting during the day.
The term "Crash program" can refer to different concepts depending on the context. Here are a few possible interpretations: 1. **Educational Context**: In some educational or training programs, a "crash course" refers to an intensive, short-term course designed to cover a large amount of material quickly. These programs are typically aimed at providing a high-level overview or foundational knowledge in a specific subject.
The planning fallacy is a cognitive bias that refers to the tendency for individuals and groups to underestimate the time, costs, and risks of future actions while overestimating the benefits. This phenomenon often leads to overly optimistic predictions about how long tasks will take and how much they will cost, resulting in delays and budget overruns. The concept was first proposed by psychologists Daniel Kahneman and Amos Tversky in 1979.
A project plan is a formal document that outlines the scope, objectives, tasks, timelines, resources, and responsibilities related to a specific project. It serves as a roadmap for project execution and management, providing guidance to the project team and stakeholders throughout the project lifecycle. Here are the key components typically included in a project plan: 1. **Project Objectives:** Clear and measurable goals that the project aims to achieve.
PK-4 refers to a specific experiment conducted on the International Space Station (ISS), focusing on the study of plasmas and their behaviors in microgravity. PK-4 is an acronym for "Plasma Kinetics 4," and it aims to investigate complex plasmas, which are ionized gases containing a significant number of charged particles and neutral gas atoms. The experiment involves creating a controlled environment to observe how these complex plasmas behave under various conditions.
Plastic is a synthetic or semi-synthetic material made from polymers, which are large molecules composed of repeating structural units known as monomers. These polymers can be derived from natural sources (like cellulose) or synthesized from petroleum, natural gas, or other chemical feedstocks. Plastics are characterized by their versatility, durability, and malleability, which allow them to be molded into various shapes and forms.
The Versatile Toroidal Facility (VTF) is a research project focused on plasma physics and fusion energy. Located at the Massachusetts Institute of Technology (MIT), the VTF is designed to investigate the behavior of plasma in a toroidal (doughnut-shaped) configuration. The facility allows researchers to explore various plasma confinement techniques and study phenomena related to magnetically confined plasma, which is critical for understanding the potential for fusion energy as a clean and sustainable energy source.
Biodegradable plastics are types of plastics that are designed to break down more quickly and efficiently than traditional plastics under certain environmental conditions. They are made from renewable resources or petrochemicals and can decompose through the action of living organisms, such as bacteria, fungi, and other biological processes. There are two main types of biodegradable plastics: 1. **Biobased Plastics**: These are made from renewable resources such as plant materials (e.g., cornstarch, 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.
