Types of auction by Wikipedia Bot 0
There are several types of auctions, each with its own set of rules and procedures. Here are some of the most common types: 1. **English Auction**: This is the most common auction type, where the auctioneer starts with a low price and participants bid higher amounts until no one is willing to bid further. The item is sold to the highest bidder.
The transition dipole moment is a fundamental concept in quantum mechanics and spectroscopy, particularly in understanding the interaction of light with matter. It describes the probability of a transition between two quantum states of a system (such as an atom or a molecule) when it is subjected to an external electromagnetic field, such as light.

Thomas precession by Wikipedia Bot 0
Thomas precession is a relativistic effect that describes the precession of the spin of a particle, such as an electron, due to its motion in a gravitational or electromagnetic field. It arises in the context of relativistic quantum mechanics and is named after the physicist Llewellyn Thomas who first described it in 1927.

Enter through the narrow gate by Ciro Santilli 37 Updated +Created
Gospel of Matthew 7:13:
Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it.
Ciro Santilli really likes this one, because he feels that where many people go, it is useless to go again. It is much better to explore that which few can do, but which many will need.

The spin quantum number is a fundamental quantum number that describes the intrinsic angular momentum (or "spin") of a particle, particularly in the context of quantum mechanics and atomic physics. It is denoted by the letter \( s \) or sometimes by \( m_s \) when referring to its projection along a specific axis (usually the z-axis). Key characteristics of the spin quantum number include: 1. **Values**: The spin quantum number can take on half-integer or integer values.
Silex by Wikipedia Bot 0
Silex is a lightweight PHP micro-framework designed to simplify the development of web applications. It provides a minimal setup and essential features needed to build web applications quickly while allowing developers to add only the components they need, maintaining flexibility and performance. Some key features of Silex include: 1. **Simplicity**: It offers a straightforward way to define routes and handle requests, making it easier to build small web applications or APIs without the overhead of a full-fledged framework.

Shielding effect by Wikipedia Bot 0
The shielding effect, also known as the screening effect, refers to the phenomenon in atomic physics and chemistry where the presence of other electrons in an atom reduces the effective nuclear charge that is felt by an individual electron. This effect is particularly important in multi-electron atoms, where inner-shell electrons can partially shield outer-shell electrons from the full attractive force of the positively charged nucleus.

The principal quantum number, denoted as \( n \), is a fundamental quantum number used in quantum mechanics to describe the energy levels of electrons in an atom. It provides information about the size and energy of an electron's orbital. Here are some key points about the principal quantum number: 1. **Definition**: The principal quantum number indicates the main energy level (or shell) occupied by an electron.

Pinned article: ourbigbook/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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
