Sombrero Function 3d
In English, a , ; ) is a type of wide-brimmed Mexican men's hat used to shield the face and eyes from the sun. It usually has a high, pointed crown; an extra-wide brim (broad enough to cast a shadow over the head, neck, and shoulders of the wearer) that is slightly upturned at the edge; and a chin strap to hold it in place. In Mexico, this hat type is known as a ('charro hat', referring to the traditional Mexican horsemen). In Spanish, any hat is considered a sombrero. Design Sombreros, like cowboy hats, were designed in response to the demands of the physical environment. High crowns provide insulation, and wide brims provide shade. Hot and sunny climates inspire such tall-crowned, wide-brimmed designs, and hats with one or both of these features have evolved again and again in history and across cultures. For example, the Greek petasos of two millennia ago, and the traditional conical hat widespread in different regions of Asiainto modern timesincorporate such heat-miti ...

Museo De Arte Popular
The Museo de Arte Popular (Museum of Folk Art) is a museum in Mexico City, Mexico, that promotes and preserves part of the Mexican handcrafts and folk art. Located in the historic center of Mexico City in an old fire house, the museum has a collection which includes textiles, pottery, glass, piñatas, alebrijes, furniture and much more. However, the museum is best known as the sponsor of the yearly Noche de Alebrijes (Night of the Alebrijes) parade in which the fantastical creatures are constructed on a monumental scale and then paraded from the main plaza or Zocalo to the Angel of Independence monument, competing for prizes. The museum The Museo de Arte Popular opened in March 2006. Its purpose is to serve as a reference for Mexican crafts as well as promoting them through workshops, and other events to both Mexico and foreign tourism. and dignify Mexican crafts though restoration of older works and the promotion of their creation both inside and outside the museum itself. ...

Apache
The Apache ( ) are several Southern Athabaskan language-speaking peoples of the Southwestern United States, Southwest, the Southern Plains and Northern Mexico. They are linguistically related to the Navajo. They migrated from the Athabascan homelands in the north into the Southwest between 1000 and 1500 CE. Apache bands include the Chiricahua, Jicarilla Apache, Jicarilla, Lipan Apache people, Lipan, Mescalero, Mimbreño Apache, Mimbreño, Salinero Apaches, Salinero, Plains Apache, Plains, and Western Apache (San Carlos Apache Indian Reservation, Aravaipa, Pinaleño Mountains, Pinaleño, Fort Apache Indian Reservation, Coyotero, and Tonto Apache, Tonto). Today, Apache tribes and Indian reservation, reservations are headquartered in Arizona, New Mexico, Texas, and Oklahoma, while in Mexico the Apache are settled in Sonora, Chihuahua, Coahuila and areas of Tamaulipas. Each Native American tribe, tribe is politically autonomous. Historically, the Apache homelands have consisted of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escaramuza Charra
Escaramuza charra is the only female equestrian event in the Mexican charrería. The escaramuza means "skirmish" and consists of a team riding horses in choreographed synchronized maneuvers to music. The women ride side-saddle and wear traditional Mexican outfit that include sombreros, dresses, and matching accessories. A team consists of 16 women, but only 8 ride at a time. The routine is practiced in a lienzo, or a circular arena. The escaramuza season runs from February to November. The U.S. nationals are held on Labor Day weekend, while the grand finales are held in Mexico that brings together over 80 teams from both sides of the border. History Charria was inspired by the vaquero culture ranching traditions during the period of colonial Mexico beginning the eighteen century northern and central Mexico. The sport was inspired "by the Mexican '' adelitas'', who fought in the Mexican Revolution." Although charrería is Mexico's national sport, there are charro ...

Sombrero Potential
Spontaneous symmetry breaking is a spontaneous process of symmetry breaking, by which a physical system in a symmetric state spontaneously ends up in an asymmetric state. In particular, it can describe systems where the equations of motion or the Lagrangian obey symmetries, but the lowest-energy vacuum solutions do not exhibit that same symmetry. When the system goes to one of those vacuum solutions, the symmetry is broken for perturbations around that vacuum even though the entire Lagrangian retains that symmetry. Overview The spontaneous symmetry breaking cannot happen in quantum mechanics that describes finite dimensional systems, due to Stone-von Neumann theorem (that states the uniqueness of Heisenberg commutation relations in finite dimensions). So spontaneous symmetry breaking can be observed only in infinite dimensional theories, as quantum field theories. By definition, spontaneous symmetry breaking requires the existence of physical laws which are invariant under a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jinc Function
A sombrero function (sometimes called besinc function or jinc function) is the 2-dimensional polar coordinate analog of the sinc function, and is so-called because it is shaped like a sombrero hat. This function is frequently used in image processing. It can be defined through the Bessel function, Bessel function of the first kind ( J_1) where . \operatorname (\rho) = \frac. The normalization factor makes . Sometimes the factor is omitted, giving the following alternative definition: \operatorname (\rho) = \frac. The factor of 2 is also often omitted, giving yet another definition and causing the function maximum to be 0.5: \operatorname (\rho) = \frac. The Fourier transform of the 2D circle function (\operatorname(\rho)) is a sombrero function. Thus a sombrero function also appears in the intensity profile of far-field diffraction through a circular aperture, known as an Airy disk.

Tampa Stadium
Tampa Stadium (nicknamed The Big Sombrero and briefly known as Houlihan's Stadium) was a large open-air stadium (maximum capacity about 74,000) located in Tampa, Florida, which opened in 1967 and was significantly expanded in 1974–75. The facility is most closely associated with the Tampa Bay Buccaneers of the National Football League, who played there from their establishment in 1976 Tampa Bay Buccaneers season, 1976 until 1997 Tampa Bay Buccaneers season, 1997. It also hosted two Super Bowls, in Super Bowl XVIII, 1984 and Super Bowl XXV, 1991, as well as the 1984 USFL Championship Game. To meet the revenue demands of the Buccaneers' new owners, Raymond James Stadium was built nearby in 1998, and Tampa Stadium was demolished in early 1999. Besides the Bucs, Tampa Stadium was home to the Tampa Bay Rowdies (1975–93), Tampa Bay Rowdies of the original North American Soccer League (1968–84), North American Soccer League, the Tampa Bay Bandits of the United States Football Lea ...

Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sombrero Galaxy
The Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is a peculiar galaxy of unclear classification in the constellation borders of Virgo and Corvus, being about from the Milky Way galaxy. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. It has an isophotal diameter of approximately , making it slightly bigger in size than the Milky Way. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its outer disk, which from Earth is viewed almost edge-on. The dark dust lane and the bulge give it the appearance of a sombrero hat (thus the name). Astronomers initially thought the halo was small and light, indicative of a spiral galaxy; but the Spitzer Space Telescope found that the halo was significantly larger and more massive than previously thought, indicative of a giant elliptical galaxy. The galaxy has an apparent magnitude of + ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baseball Cap
A baseball cap is a type of soft cap, hat with a rounded crown and a stiff bill projecting in front. The front of the hat typically displays a design or a logo (historically, usually only a sports team, namely a baseball team, or names of relevant companies, when used as a commercial marketing technique). The hat may be "fitted" to the wearer's head or the back may have Stretch fabric, elastic, a plastic prong-in-a-hole (multiple holes with one prong that can be inserted), Hook and loop fastener, Velcro, a zipper, or a tri-glide slide so that it can be quickly adjusted to fit different wearers' heads. The baseball hat is a part of the traditional baseball uniform worn by players, with the brim pointing forward to shield the eyes from the sun. Since the 1980s, varieties of the hat have become prevalent in the United States and many other nations, both for utilitarian (protecting the eyes from the sun) and fashion accessory purposes. History In 1860, the Brooklyn Excelsiors wore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
