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 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.

Transition Path Sampling (TPS) is a computational technique used in statistical mechanics and molecular dynamics to study rare events, particularly transitions between different states of a system. This method is particularly useful for exploring processes that require significant energy barriers to overcome, such as conformational changes in biomolecules, chemical reactions, or phase transitions. **Key Concepts of Transition Path Sampling:** 1. **Transition Events:** TPS focuses on the trajectories (paths) that link two distinct states or configurations of a system over time.
Self-cleaning glass is a type of glass that has been specially treated to reduce the accumulation of dirt and grime, making it easier to keep clean. This technology typically utilizes a combination of hydrophilic and photocatalytic properties. 1. **Hydrophilic Coating**: The surface of self-cleaning glass is coated with a hydrophilic substance, which means it has an affinity for water.
Forisome is a term that refers to a type of specialized structure found in certain plants, particularly in the family of legumes (Fabaceae). These structures are typically slender, elongated, and may be involved in the dispersal of seeds or in other biological functions related to the plant's reproduction or survival. In some contexts, the term "forisome" is used to describe a specific type of cell or tissue that can expand or contract in response to environmental stimuli.

Religious faiths, traditions, and movements are key components of human spirituality and cultural identity. They encompass a wide range of beliefs, practices, and organizational structures that relate to the sacred or the divine. Here’s a brief overview of each component: ### 1. Religious Faiths: Religious faiths refer to the overarching belief systems that provide followers with a framework for understanding the universe, meaning, morality, and the nature of the divine.
Parity learning is a concept that typically refers to a type of learning or training strategy in machine learning and artificial intelligence, particularly in the context of learning from imbalanced or challenging datasets. The term can have specific meanings depending on the domain and context. In general, the idea behind parity learning involves ensuring that the model or system can recognize and properly weigh instances of different classes or categories, especially in scenarios where one class may be underrepresented.

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.
