TRIFIC-program by Wikipedia Bot 0
As of my last knowledge update in October 2021, specific details about a "TRIFIC program" were not available, as it may not have been widely recognized or it might be a term that has emerged more recently. It's possible that "TRIFIC" could refer to a program, initiative, or framework within various fields such as technology, education, healthcare, or marketing, among others.
Throwing games by Wikipedia Bot 0
"Throwing games" can refer to a variety of activities or sports that involve the act of throwing an object. The specifics can vary widely depending on the context, but generally, they include the following types: 1. **Sports**: Many traditional sports involve throwing, such as: - **Baseball**: Pitchers throw the ball to batters. - **Football**: Quarterbacks throw the ball to receivers.
Bat flip by Wikipedia Bot 0
A "bat flip" refers to the act of a baseball player, typically after hitting a home run, dramatically flipping or tossing their bat away rather than simply dropping it to the ground. This gesture is often seen as an expression of excitement and celebration, showing off the player's emotions after making a good hit. However, bat flips can be controversial in baseball culture. Some fans and players view them as disrespectful to the opposing team, especially when done excessively or in a confrontational manner.
In baseball, "submarine" refers to a style of pitching characterized by an unconventional throwing motion where the pitcher releases the ball with an arm angle that is very low, often near or below the horizontal plane. This delivery is akin to the motion used by a submariner, hence the name. Submarine pitchers typically throw sidearm or underhand, and their unique arm angle can result in a variety of pitches with unusual movement.
Ab initio quantum chemistry methods are computational techniques used to study the electronic structure of molecules and their interactions based on quantum mechanics, without relying on empirical parameters or experimental data. "Ab initio" is a Latin phrase meaning "from the beginning," indicating that these methods derive results purely from fundamental principles rather than fitting models to experimental data.
In chemistry, particularly in the field of quantum chemistry and computational chemistry, a **basis set** is a collection of functions used to describe the electronic wave functions of atoms and molecules. These functions serve as a mathematical representation of the electronic structure of a system, allowing researchers to perform calculations on molecular properties and reactions.
Isoelectronicity by Wikipedia Bot 0
Isoelectronicity refers to the condition in which two or more entities (such as atoms, ions, or molecules) have the same number of electrons and, consequently, the same electronic structure. Because of this shared electronic configuration, isoelectronic species often exhibit similar chemical and physical properties.
Metadynamics by Wikipedia Bot 0
Metadynamics is a computer simulation method used in the field of computational chemistry and molecular dynamics to explore the free energy landscape of a system. The technique is particularly useful for studying rare events, such as chemical reactions, conformational changes in biomolecules, or phase transitions, which can occur over timescales that are prohibitively long for conventional molecular dynamics simulations.

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.
