Skookumchuck Narrows is a tidal waterway located in British Columbia, Canada, between the Sunshine Coast and the Sechelt Peninsula, near the town of Egmont. The name "Skookumchuck" is derived from a Chinook Jargon term meaning "strong water," which aptly describes the powerful currents and tidal changes that occur in the narrows.
Shielding gas is a type of gas used in welding processes to protect the weld area from atmospheric contamination. Shielding gases are essential for achieving high-quality welds, as they help to prevent oxidation, contamination, and other reactions that can weaken the weld or lead to defects.
Shot welding is a process used to join materials, typically metals, by applying a series of small metal projectiles or "shots" at high velocities. The process is characterized by its ability to produce a fusion bond without the need for traditional welding equipment such as a weld pool or filler material. Here’s a general overview of how shot welding works: 1. **Preparation**: The surfaces of the materials to be joined are cleaned and prepared to ensure optimal bonding.
Epistemic virtue refers to the qualities or traits that contribute to the acquisition, justification, and dissemination of knowledge.

The kanal is a unit of area commonly used in some South Asian countries, particularly in Pakistan and parts of India, to measure land. One kanal is equivalent to 20 marlas, where one marla is traditionally understood to be 272.25 square feet. Therefore, one kanal is approximately 5,445 square feet or about 505.857 square meters. The kanal is often used in the context of real estate and agriculture.
The rai is a unit of area used in Thailand, primarily for measuring land. One rai is equivalent to 1,600 square meters or approximately 0.395 acres. It is commonly used in real estate and agriculture in Thailand for land transactions and property descriptions. The unit is part of a traditional Thai system of measurement that includes other units such as ngan and square wah.
The foot-poundal (often abbreviated as ft·pd or simply ft·pdl) is a unit of energy or work in the foot-pound system, which is primarily used in some fields of engineering and physics in the United States. It is defined as the amount of energy exerted when a force of one poundal (a unit of force) is applied over a distance of one foot.
Foot-lambert (abbreviated as ft-L) is a unit of measurement used to quantify luminance, which is the amount of light that is emitted, transmitted, or reflected from a surface in a specific direction. Specifically, it is defined as the luminance of a surface that emits or reflects one lumen per square foot. In different contexts, luminance is an important measure for assessing how bright a surface will appear to the human eye under various lighting conditions.
A Masha is a traditional unit of mass that is used in parts of South Asia, particularly in India and Pakistan. It is primarily associated with measuring precious metals, such as gold and silver. One Masha is approximately equivalent to 0.025 grams, but its exact value can vary depending on local customs and practices. Historically, it has been used in commerce and trade, especially in the context of jewelry and traditional markets.
The stilb is a unit of luminous intensity, specifically used in photometry to quantify the brightness of a surface in a particular direction. It is defined as the luminous intensity of a surface that emits light uniformly in all directions, with a luminous flux of one lumen per square meter. The unit is named after the Greek word "stilbos," which means "brightness" or "shine.
In the context of group theory, a *discontinuous group* usually refers to a group of transformations that is not continuous in a topological sense. This term can have different meanings depending on the mathematical context in which it is used, but here are two key interpretations: 1. **Mathematical Groups and Topology**: In general topology, a discontinuous group may refer to a group of homeomorphisms that do not form a continuous path between their elements.

A lumen is a unit of measurement used to quantify the amount of visible light emitted by a source. It is part of the International System of Units (SI) and is used to express luminous flux, which is the total amount of light output from a light source as perceived by the human eye.
The term "2019 software" could refer to various software products or updates that were released in or around the year 2019. However, it is often associated with certain popular applications that had notable releases or updates in that year. Here are a few examples: 1. **Microsoft Office 2019**: This is a version of Microsoft's productivity suite that includes applications like Word, Excel, PowerPoint, and more.
The term "ounce" has several meanings and uses, primarily related to measurements. Here are the two most common contexts: 1. **Fluid Ounce**: A unit of volume commonly used in the United States and the UK, particularly for measuring liquids. In the United States, one fluid ounce is equal to approximately 29.57 milliliters, while in the UK, it is about 28.41 milliliters.
P50, in the context of pressure, often refers to a specific measurement related to the partial pressure of a gas in a mixture, particularly in biological or biochemical contexts. For instance, in the field of respiratory physiology, P50 is commonly associated with the partial pressure of oxygen (pO2) at which hemoglobin is 50% saturated with oxygen.
The term "types of year" can refer to various ways of measuring time across different contexts, such as astronomical, calendar, and fiscal years. Here are some of the common types of years: 1. **Calendar Year**: - The period from January 1 to December 31, typically consisting of 365 days in a common year and 366 days in a leap year.

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.
