Russian formalism was a literary and aesthetic movement that emerged in Russia in the early 20th century, particularly in the 1910s and 1920s. It was primarily concerned with the study of literature as a distinct form of art, emphasizing the formal aspects of literary works rather than their content or social context. The movement sought to analyze the structures, techniques, and devices used in literature to create meaning and generate aesthetic effects.
Belgium is divided into three regions: Flanders, Wallonia, and the Brussels-Capital Region. Each region is further subdivided into municipalities, which are the basic administrative units in the country. As of my last update, there are 589 municipalities in Belgium. These municipalities vary significantly in size and population. For example: - **Flanders**: The northern region, where Dutch is the official language, comprises many municipalities, including larger cities like Antwerp, Ghent, and Bruges.
Kotoamatsukami is a fictional ability from the "Naruto" manga and anime series created by Masashi Kishimoto. It is a special genjutsu technique performed by users of the Uchiha clan, particularly associated with the Sharingan, a powerful dojutsu (visual jutsu). Kotoamatsukami allows the user to manipulate the target's mind without them being aware of the manipulation.
A Dark Matter Time Projection Chamber (TPC) is a type of particle detector designed to search for dark matter interactions, specifically weakly interacting massive particles (WIMPs), which are one of the leading candidates for dark matter. The TPC combines the principles of time projection chambers with specialized materials and techniques suited for detecting the minute interactions that dark matter particles might produce.
Gas electron diffraction (GED) is a technique used to study the molecular structure of gas-phase samples by examining the scattering of electrons as they pass through a gas. It can be particularly useful for obtaining information about small molecules, radicals, and other transient species that may not have a stable crystalline form or that would be difficult to study using traditional X-ray crystallography.
The Kapitsa–Dirac effect is a quantum phenomenon that occurs when a beam of particles, such as electrons, interacts with a periodic potential in a way that results in the diffraction of the particles into discrete energy states. This effect was first predicted by physicists Peter Kapitsa and Paul Dirac in the 1930s.
Ultrasonic grating is a technique that involves the use of ultrasonic waves to create a pattern or grating effect in a medium. This method can be applied in various fields, such as materials science, acoustics, and engineering, and can serve multiple purposes including diagnostics, imaging, and material characterization. In essence, ultrasonic grating works by generating high-frequency sound waves that can propagate through different materials.
The Rydberg–Ritz combination principle is a concept in the field of spectroscopy that relates to the spectral lines of atoms, particularly hydrogen. It was formulated in the early 20th century based on the work of physicists Johannes Rydberg and Walther Ritz.
Vibrational energy relaxation refers to the process by which vibrational energy, which is the energy associated with the vibrational motion of atoms within a molecule, dissipates or transitions to other forms of energy, typically in a condensed phase or gas. This process is significant in various fields, including physical chemistry, materials science, and biophysics, as it plays a critical role in energy transfer mechanisms, chemical reactions, and the behavior of complex systems.
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique used to determine the structure and dynamics of molecules, including carbohydrates. In the context of carbohydrates, NMR spectroscopy provides valuable information about their chemical structure, conformation, and interactions. ### Key Aspects of NMR Spectroscopy of Carbohydrates: 1. **Principle**: NMR relies on the magnetic properties of certain atomic nuclei, primarily hydrogen (^1H) and carbon (^13C) nuclei in carbohydrates.
Thunder deities are divine beings associated with thunder and often storms, representing the power and might of nature. They appear in various mythologies around the world and are typically seen as gods or spirits who can control or wield the forces of thunder, lightning, and storms. Some notable thunder deities include: 1. **Thor** (Norse Mythology) - The god of thunder, known for his hammer Mjölnir, which produces thunder and lightning.
The Rainflow counting algorithm is a method used to analyze the cycle counts of varying loads, particularly in the fields of structural engineering and fatigue analysis. Its primary purpose is to identify and quantify the cyclic loading patterns experienced by materials, components, or structures over time, which is essential for assessing fatigue life and durability.
Weather insurance is a type of insurance that provides financial protection against losses resulting from adverse weather conditions. It is often used by businesses and individuals whose operations or income are affected by weather events, such as farmers, event planners, and outdoor venues. Here are some key points about weather insurance: 1. **Coverage Types**: Weather insurance can cover various weather-related events, such as droughts, excessive rain, snow, frost, or high temperatures. The specific terms of coverage depend on the policy.
Deep learning by Ciro Santilli 40 Updated 2025-07-16
Deep learning is the name artificial neural networks basically converged to in the 2010s/2020s.
It is a bit of an unfortunate as it suggests something like "deep understanding" and even reminds one of AGI, which it almost certainly will not attain on its own. But at least it sounds good.

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.
