Eigen, Schwyz
Alpthal is a village and municipality in Schwyz District in the canton of Schwyz in Switzerland. Besides the village of Alpthal, the municipality includes the ski resort of Brunni, and settlement of Eigen. History Alpthal is first mentioned in 1018 as ''Albetal''. A branch of the Camino de Santiago pilgrimage route connected Einsiedeln with Schwyz via Alpthal and the Haggenegg. Winter tourism first came to Alpthal in 1950, with the opening of the cable car from Brunni to the Holzegg. Brunni acquired its first ski lift in 1964, and the Brunni-Haggenegg ski area was commissioned in 1974. Geography The village of Alpthal is located in the upper reaches of the Alptal, the valley of the river Alp upstream from Einsiedeln. Also within the municipality of Alpthal are the popular ski resort of Brunni, higher up the valley, and the settlement of Eigen, down the valley. To the north and beyond Eigen, the Alp flows through the village Trachslau and further through the town of Einsie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manfred Eigen
Manfred Eigen (; 9 May 1927 – 6 February 2019) was a German biophysical chemist who won the 1967 Nobel Prize in Chemistry for work on measuring fast chemical reactions. Eigen's research helped solve major problems in physical chemistry and aided in the understanding of chemical processes that occur in living organisms. In later years, he explored the biochemical roots of life and evolution. He worked to install a multidisciplinary program at the Max Planck Institute to study the underpinnings of life at the molecular level. His work was hailed for creating a new scientific and technological discipline: evolutionary biotechnology. Education and early life Eigen was born on 9 May 1927 in Bochum, the son of Hedwig (Feld) and Ernst Eigen, a chamber musician. As a child he developed a deep passion for music, and studied piano. World War II interrupted his formal education. At age fifteen he was drafted into service in a German antiaircraft unit. He was captured by the Soviets ...

Saint Eigen
Saint Eigen, Eurgen, Eurgain or Eurgan was the legendary, and possibly historical first female Christian saint among the Britons. Her name has doubtfully been linked to two Welsh churches and is found in manuscripts from the collection of Iolo Morganwg making historical evidence of her existence dubious and limited. Eigen is noted as the daughter of Caratacus in the History of Dunraven Manuscript, a manuscript giving the genealogy of Taliesin from the collection of Thomas Hopkin of Coychurch, one from the Havod Uchtryd collection and in an extract he claimed to have copied from the Long Book of Thomas Truman. This reference can also be found in the family records of Iestyn ab Gwrgant, where it is said of her; ''"She lived in the close of the first century, and was married to Sarllog, who was a lord of Caer Sarllog, or the present Old Sarum"''. In this manuscript, Eigen is said to have returned from Rome with Caratacus with Saint Cyllin and Saint Ilid and formed a religio ...

Eigenvalue, Eigenvector And Eigenspace
In linear algebra, an eigenvector () or characteristic vector of a linear transformation is a nonzero vector that changes at most by a scalar factor when that linear transformation is applied to it. The corresponding eigenvalue, often denoted by \lambda, is the factor by which the eigenvector is scaled. Geometrically, an eigenvector, corresponding to a real nonzero eigenvalue, points in a direction in which it is stretched by the transformation and the eigenvalue is the factor by which it is stretched. If the eigenvalue is negative, the direction is reversed. Loosely speaking, in a multidimensional vector space, the eigenvector is not rotated. Formal definition If is a linear transformation from a vector space over a field into itself and is a nonzero vector in , then is an eigenvector of if is a scalar multiple of . This can be written as T(\mathbf) = \lambda \mathbf, where is a scalar in , known as the eigenvalue, characteristic value, or characteristic root ...

Metaclass
In object-oriented programming, a metaclass is a class whose instances are classes. Just as an ordinary class defines the behavior of certain objects, a metaclass defines the behavior of certain classes and their instances. Not all object-oriented programming languages support metaclasses. Among those that do, the extent to which metaclasses can override any given aspect of class behavior varies. Metaclasses can be implemented by having classes be first-class citizens, in which case a metaclass is simply an object that constructs classes. Each language has its own metaobject protocol, a set of rules that govern how objects, classes, and metaclasses interact. Python example In Python, the builtin class type is a metaclass. Consider this simple Python class: class Car: def __init__(self, make: str, model: str, year: int, color: str): self.make = make self.model = model self.year = year self.color = color @property def description(se ...
