"Metamaterial" Natural Recordings by Native Speakers
A metamaterial is a material engineered to have properties not found in nature, often with novel or unprecedented characteristics, such as negative refractive index, perfect absorption of electromagnetic radiation, or control over electromagnetic waves. These properties arise from the specific arrangement of its constituent particles, such as atoms, molecules, or nanoparticles, rather than the properties of the materials themselves.
Metallurgists are scientists and engineers who study the properties and applications of metal alloys, and who develop and improve techniques for extracting, refining, and manufacturing metals from ores. They work in industries such as mining, manufacturing, and research, and may specialize in specific areas such as ferrous metallurgy (working with iron and steel) or non-ferrous metallurgy (working with metals like copper, aluminum, and gold).
Metalocalypse is a term that refers to a fictional apocalyptic event in which the end of the world is brought about or hastened by a catastrophic failure or misuse of metal music or heavy metal culture.
Metals are a class of chemical elements that are typically hard, shiny, malleable, and good conductors of electricity and heat. They are often found naturally, such as in ores, or can be produced synthetically. Metals are commonly used in construction, electronics, and other industries due to their strength, durability, and ability to withstand high temperatures. Examples of metals include copper, iron, gold, silver, and aluminum.
Metalware refers to objects or items made of metal, such as cutlery, dishes, pots and pans, utensils, and other household items. It can also refer to decorative or ornamental metal products, like candelabras, vases, or lampstands. The term typically implies that the item is made primarily or entirely of metal, and is often used to distinguish it from items made of other materials, such as plastic or ceramic.
Metalwork is the process of shaping and forming metal using various techniques and tools, such as cutting, bending, drilling, and welding, to create a specific design or structure. It is a type of craftsmanship that requires a range of skills, including precision, patience, and attention to detail. Metalworkers use metal materials, such as steel, aluminum, copper, and other alloys, to create a wide range of products, including machinery, tools, furniture, decorative items, and industrial equipment.
A person who works with metal to create or shape various objects, such as tools, machinery, or decorative items. Metalworkers may specialize in specific techniques or industries, like welding, soldering, or foundry work, and often require specialized training or apprenticeships to master their craft.
Metamer is a noun that refers to a property or characteristic of two objects that appears the same when viewed under different conditions, such as color, light, or perspective. In other words, metamerism is the phenomenon where two objects have the same visual appearance, but are actually different in terms of their color composition or other properties. This concept is often encountered in fields like design, art, and color science.
Metamere refers to a segment or division of a body part that is repeated during embryonic development, resulting in similar structures such as vertebrae in the spine or digits on a limb. It can also refer to a repeated structural unit or morphological feature in a developing organism, such as the repetition of horns or nipples in certain animals.
Metameres are segments or divisions of an animal's body that are similar in structure and function, but are not necessarily identical. The term is often used in zoology to describe the repeating patterns of segments found in certain animal bodies, such as insects, worms, and some fish.
Metameric refers to a sequence of colors that are next to each other on the color spectrum and appear to change gradually from one to the next. In other words, metameric colors are those that are "complexly adjacent" on the color wheel, often creating a sense of continuity and harmony.
Metamerically refers to the phenomenon where two colors, even though they have different wavelengths of light, are perceived as having the same hue or color by the human eye. This occurs because the colors have identical reflectance spectrums, even if their absolute amounts of luminance are different. Metamerism is often used in color reproduction and color matching, as it allows for the creation of colors that may appear identical to the human eye, even if the underlying wavelengths of light are slightly different.
Metamerism refers to the phenomenon where two different colors or pigments appear the same when viewed under different lighting conditions, despite being chemically distinct and with different spectral reflectance curves. In other words, metamerism is the illusion of color equality between two different colors. This occurs when the color characteristics of the two colors are similar enough that the differences in their color appearance are indistinguishable to the human eye, often due to variations in illumination or ambient light.
Metamers refers to a phenomenon where two different light stimuli are perceived as identical by the human eye and brain. It is also known as a "metamer pair". In other words, metamers are two lights that have different spectral power distributions, but are perceived as having the same color by the viewer.
Metamizol is a brand name for the medication amidopyrine, which is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to treat pain and reduce inflammation. It is often prescribed to relieve mild to moderate pain, as well as to reduce fever and inflammation.
