The Schoenflies problem is a question in the field of topology, specifically concerning the embedding of spheres in Euclidean spaces. It is named after the mathematician Rudolf Schoenflies. The problem essentially asks whether every simple, closed curve in three-dimensional space can be "filled in" by a disk, or in more technical terms, whether every homeomorphism of the 2-sphere (the surface of a solid ball) can be extended to a homeomorphism of the solid ball itself.

In mathematics, particularly in the field of differential geometry, a **submanifold** is a subset of a manifold that itself has the structure of a manifold, often with respect to the topology and differential structure induced from the larger manifold.

Faà di Bruno's formula provides a way to compute the \( n \)-th derivative of a composed function. It generalizes the chain rule for differentiation in a systematic way.

The term "reciprocal rule" can refer to different concepts depending on the context in which it's used. Below are a few interpretations of the term: 1. **Mathematics**: In mathematics, particularly in the context of fractions or division, the reciprocal of a number is defined as \(1\) divided by that number.

A diffraction grating is an optical component with a periodic structure that diffracts light into several beams. The grating consists of multiple closely spaced slits or grooves, which can be either reflective or transmissive. When light waves encounter the grating, they are scattered at specific angles according to the principles of wave interference, producing a spectrum of colors.

"Discoveries" by Juraj Tóth is not a widely recognized title in mainstream literature, art, or scientific fields up to my last update in October 2023. However, there may be specific niche areas or emerging works that have not gained significant attention yet. Juraj Tóth could also be involved in various domains, such as scientific research, literature, or academia.

CORDIC, which stands for COordinate Rotation DIgital Computer, is an algorithm used for calculating trigonometric functions, hyperbolic functions, exponentials, logarithms, and square roots, among other operations. It was first introduced by Volder in 1959 and has become a popular method for implementing these calculations in hardware, particularly in dedicated digital processors and embedded systems where resources are limited.

Poker video games are digital adaptations of the traditional card game of poker. These games can be played on various platforms, including personal computers, consoles, and mobile devices. They range from casual, social games where players can compete against friends and other online players to more serious simulations that mimic professional poker environments. ### Types of Poker Video Games 1. **Online Poker Rooms**: These are platforms where players can join real-money or play-money games.

Powder diffraction is a scientific technique used to analyze the crystalline structure of materials in powder form. This method is commonly employed in fields such as materials science, chemistry, geology, and metallurgy to determine the arrangement of atoms within a crystalline solid. **Key features of powder diffraction include:** 1. **Sample Requirements**: The sample must be in powder form, which allows the random orientation of crystallites.

Kinematic diffraction is a concept in the field of X-ray diffraction and crystallography that describes the way X-rays scatter off a crystalline material. It is based on kinematic theory, which simplifies the treatment of diffraction by considering the contributions of each atom in the crystal independently, without accounting for multiple scattering events. In kinematic diffraction, the following key points apply: 1. **Single Scattering**: It assumes that each X-ray photon interacts with one atom and is scattered only once.

"Bicycle Casino" is a video game that simulates the experience of gambling in a casino setting. Developed by the team behind the popular "Bicycle" card brand, the game offers players a variety of casino games, including poker, blackjack, and other classic games traditionally found in casinos. The game may feature realistic graphics, sound effects, and a user-friendly interface to immerse players in the gambling experience. It can be played on different platforms, including personal computers and gaming consoles.

Pocket Card Jockey is a uniquely designed video game that combines elements of card games with horse racing. Developed by Game Freak and published by Nintendo, it was initially released for the Nintendo 3DS in 2016. The gameplay integrates various mechanics, where players use a standard deck of playing cards to influence their horse's performance during races. In Pocket Card Jockey, players manage a stable of horses, selecting cards to affect various aspects of the race, such as speed and stamina.

The Scherrer equation is a formula used in materials science and crystallography to estimate the size of crystalline domains in a material based on X-ray diffraction data. It provides a way to quantify the average size of coherently diffracting crystallites or grains within a sample. The equation is particularly useful for nanomaterials and thin films.

Selected Area Diffraction (SAD) is a technique used in transmission electron microscopy (TEM) to analyze the crystallographic structure of materials. It allows researchers to obtain diffraction patterns from a specific area of a sample rather than from the entire specimen. This technique is particularly useful for studying the local structural properties of crystalline materials, including defects, phase composition, and orientation.

Ultrafast electron diffraction (UED) is a powerful experimental technique used to investigate dynamic processes in materials and molecular systems on very short timescales, typically in the femtosecond (10^-15 seconds) regime. It combines concepts from electron diffraction with ultrafast laser technology to capture real-time structural changes in materials as they undergo rapid transformations.

Closing in morphology refers to a process that involves the formation of morphemes by combining existing morphemes or modifying them. It typically describes how morphological structures can be completed or finalized, which can include morphological processes like affixation (adding prefixes or suffixes), compounding (combining two or more stems), or alternation (changing the form of a morpheme to express different grammatical categories).

The Dolinar receiver is a type of communication protocol designed for use in wireless systems, particularly in scenarios involving low-power and low-bandwidth data transmission. It is named after the researcher who introduced the concept, and it is primarily used in the context of secure communications, such as those found in satellite and mobile communications.

"Slay the Spire" is a roguelike deck-building video game developed by the indie studio MegaCrit. Released in early access in 2017 and fully in 2020, the game combines elements of card games, strategy, and role-playing. In "Slay the Spire," players choose one of several characters, each with unique abilities and cards, to ascend a randomly generated spire divided into multiple levels.

"**Mario's Game Gallery**" is a video game released for the PC in 1995. It is a collection of classic board games and card games featuring characters from the Mario franchise. The game was developed by GameTek and includes popular games such as chess, checkers, go, and backgammon. In "Mario's Game Gallery," players can compete against various Mario characters, and the game's design is aimed at younger audiences, presenting a friendly and colorful interface.

Top Trumps: Doctor Who is a card game based on the popular British television series "Doctor Who." In the game, players use specially designed cards that feature various characters, creatures, and elements from the series. Each card has statistics or attributes representing different aspects such as power, intelligence, or other distinctive features. The objective of the game is to win cards from other players by comparing these attributes.
