It serves as a reference tool to help students, educators, and professionals understand and communicate scientific concepts more effectively. Below is a selection of important chemistry terms along with their definitions: ### Glossary of Chemistry Terms 1.
"Lumen Naturae," which translates to "Light of Nature," is a philosophical concept that suggests an inherent order or reason within the natural world that can be accessed through human reason and observation. It embodies the idea that nature has its own guiding principles, and by contemplating nature, people can gain insights into moral and ethical truths. The term has been used in various contexts, including in the works of philosophers like John Locke and in the development of natural law theory.
Electrical tuning refers to the process of adjusting the electrical properties of a device or circuit to achieve a desired performance or operational characteristic. This can involve modifying parameters such as frequency, impedance, voltage, or other electrical characteristics. In different contexts, electrical tuning can have specific meanings: 1. **Radio and Communication Systems**: In radio technology, electrical tuning pertains to the adjustment of radio receivers to specific frequencies to select desired channels or signals while filtering out others.
Electric current is the flow of electric charge in a conductor, typically measured in amperes (A). It represents the movement of electrons through a material, and this movement can occur in various forms, such as direct current (DC), where the flow of charge is uniform and directional, or alternating current (AC), where the flow periodically reverses direction. In a circuit, electric current is driven by a voltage difference (potential difference) created by a power source, such as a battery or generator.
The term "866A" could refer to different things depending on the context. Here are a few possibilities: 1. **Telephone Number**: In some contexts, it could refer to a phone number with the area code 866, which is a toll-free area code in North America. 2. **Regulatory or Legal Code**: It might refer to a specific code, standard, or regulation.
A "control grid" is a term that can refer to different concepts depending on the context in which it is used. Below are a couple of common interpretations of the term: 1. **In Electronics (Vacuum Tubes):** In the context of vacuum tubes, a control grid is an electrode that is used to control the flow of electrons between the cathode and the anode (plate).
Electron-beam welding (EBW) is a fusion welding process that uses a narrow, focused beam of high-velocity electrons to join materials, typically metals. The technique is often used in industrial applications for its ability to produce high-quality welds with minimal thermal distortion and a small heat-affected zone.
An electron gun is a device that generates and emits a stream of electrons, typically in a vacuum environment. It consists of several key components that work together to produce and control a focused electron beam. Electron guns are commonly used in various applications, including: 1. **Cathode Ray Tubes (CRTs)**: In traditional television sets and computer monitors, electron guns are used to direct beams of electrons onto a phosphorescent screen, creating images.
Electronic skin, often referred to as e-skin, is a flexible, stretchable, and often self-healing material designed to mimic the properties and functions of human skin. It is embedded with sensors that can detect various types of stimuli, such as pressure, temperature, humidity, and even chemical signals. This advanced technology is a significant area of research in fields such as robotics, prosthetics, and wearable electronics, offering a range of potential applications.

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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
