In EELS, the "magic angle" typically refers to an angle of approximately 54.
Gustav Victor Rudolf Born is a prominent British pharmacologist and biochemist known for his significant contributions to the fields of pharmacology and molecular biology. Born on December 23, 1920, he is particularly recognized for his work on blood coagulation, the role of platelets in hemostasis, and various aspects of drug action and toxicity. He is also known for his research on the mechanisms of drug action and physiological processes such as blood clotting.
"**Puppets**" can refer to various concepts depending on the context in which it's used. Here are a few common interpretations: 1. **Theatrical Puppets**: In the realm of performing arts, puppets are figures that are manipulated by a performer, often called a puppeteer. They can come in various forms, including hand puppets, marionettes (which are controlled by strings), shadow puppets, and more.
Traditional dolls refer to a wide variety of dolls that are created based on cultural, historical, or regional customs. These dolls often reflect the clothing, characteristics, and traditions of specific societies or communities. They can serve various purposes, including as toys, collectors' items, or cultural symbols. Here are some key aspects of traditional dolls: 1. **Cultural Representation**: Traditional dolls often embody the attire, craftsmanship, and cultural symbols of a particular group.
An action figure is a posable toy figure, often representing a character from movies, television shows, comic books, or video games. Typically made of plastic, action figures are designed to resemble a specific character and often come with accessories, such as weapons or vehicles, to enhance playability. They can vary in size, detail, and articulation, with some being highly detailed collector’s items while others are designed more for play by children.
An art doll is a handcrafted artistic creation that emphasizes uniqueness and expression rather than functionality or commercial production. Art dolls can come in various forms, materials, and styles, ranging from high-end collectibles to whimsical, imaginative figures. They may be made of materials like cloth, clay, porcelain, or mixed media, and often incorporate intricate details, elaborate costumes, and expressive features. Art dolls are typically created by artists who seek to convey a concept, tell a story, or evoke emotions through their work.
A "baby simulator" typically refers to a type of electronic or software-based simulation designed to mimic the experience of caring for a baby. These simulations can be used for various purposes, including education, entertainment, and parenting preparation. Here are some common contexts in which baby simulators are used: 1. **Educational Tools**: These simulators are often used in parenting classes or schools to teach individuals about child care, parenting responsibilities, and the challenges of raising a baby.
Billiken is a figure that originated in the early 20th century, often described as a symbol of good luck and happiness. It resembles a chubby, elf-like figure with a smiling face, pointed ears, and a tuft of hair on its head, often depicted sitting or reclining. The Billiken was created by an American art teacher named Florence Pretz in 1908.
A bisque doll is a type of doll made from unglazed porcelain, often characterized by its matte finish and lifelike appearance. The term "bisque" refers to the technique used to create the material, which involves firing the clay at a high temperature to produce a durable, porcelain-like substance. Bisque dolls are typically valued for their detailed, hand-painted features, including facial expressions and intricate hairstyles. They often have jointed limbs, allowing them to be posed in various positions.
A bobblehead is a type of collectible doll or figurine characterized by a oversized head that is attached to a spring or a flexible joint, allowing the head to bobble or nod when moved or shaken. Typically, bobbleheads are designed to resemble specific characters, celebrities, athletes, or even fictional characters.
A composition doll is a type of doll that is made from a composite material, typically a blend of wood pulp, sawdust, and other organic materials, which are then mixed with a binding agent and molded into shape. This type of doll was popular during the early to mid-20th century, especially from the 1900s to the 1950s. Composition dolls were often less expensive than porcelain dolls and were lighter, making them more appealing to children.
Imaging spectroscopy is an advanced remote sensing technique that combines imaging and spectroscopy to capture and analyze the spectral information of an object's surface across a wide range of wavelengths. Unlike traditional imaging, which typically only captures information in visible light or a few discrete bands, imaging spectroscopy acquires data across many narrow, contiguous spectral bands, allowing for detailed analysis of the materials' properties and compositions.
Infrared photodissociation spectroscopy (IRPD) is a powerful analytical technique used primarily in molecular spectroscopy to study the structure and dynamics of molecules, particularly ions and complexes. Here's a brief overview of the method: ### Principles: 1. **Infrared Absorption:** The technique relies on the absorption of infrared (IR) radiation by molecules. Molecules have specific vibrational modes that correspond to particular wavelengths of IR light. When IR light is absorbed, it can excite these vibrational modes.
The Inglis–Teller equation is a mathematical expression used in the field of atomic physics and quantum mechanics to describe the behavior of electrons in a quantum system, particularly in the context of atomic ionization processes. It is named after physicists A. R. Inglis and R. Teller, who developed the equation to provide insights into the ionization of atoms in strong electric fields.
Internal conversion is a non-radiative process in chemistry and physics where an excited molecule transitions to a lower energy state (usually the ground state) without the emission of a photon. Instead of releasing energy as light, the molecule dissipates the energy as vibrational or thermal energy to its surroundings. In more detail, when a molecule absorbs energy and moves to an excited electronic state, it may undergo various relaxation processes to return to a lower energy state.
Intervalence charge transfer (IVCT) refers to a molecular electronic transition in which an electron is transferred between two metal centers that have different oxidation states within a complex, typically in mixed-valence compounds. This type of charge transfer occurs in systems where there are two or more closely spaced metal ions, and at least one is in a different oxidation state from the others.
A "straw man" argument is a rhetorical device or logical fallacy where someone misrepresents, oversimplifies, or distorts an opponent's argument to make it easier to attack or refute. Instead of engaging with the actual position or reasoning of the opponent, the person creates a "straw man" version of the argument that is weaker and easier to refute.
The term "Dutch astrophysicists" generally refers to scientists from the Netherlands who specialize in astrophysics, the branch of astronomy that deals with the physical properties and behavior of celestial objects and phenomena. Dutch astrophysicists have made significant contributions to various areas of research, including cosmology, stellar dynamics, planetary science, and the study of galaxies.
