William Eduard Weber
Wilhelm Eduard Weber (; ; 24 October 1804 – 23 June 1891) was a German physicist and, together with Carl Friedrich Gauss, inventor of the first electromagnetic telegraph. Biography of Wilhelm Early years Weber was born in Schlossstrasse in Wittenberg, where his father, Michael Weber, was professor of theology. The building had previously been the home of Abraham Vater. Wilhelm was the second of three brothers, all of whom were distinguished by an aptitude for science. After the dissolution of the University of Wittenberg his father was transferred to Halle in 1815. Wilhelm had received his first lessons from his father, but was now sent to the Orphan Asylum and Grammar School at Halle. After that he entered the University, and devoted himself to natural philosophy. He distinguished himself so much in his classes, and by original work, that after taking his degree of Doctor and becoming a ''Privatdozent'' he was appointed Professor Extraordinary of natural philosophy ...

Wittenberg
Wittenberg ( , ; Low Saxon language, Low Saxon: ''Wittenbarg''; meaning ''White Mountain''; officially Lutherstadt Wittenberg (''Luther City Wittenberg'')), is the fourth largest town in Saxony-Anhalt, Germany. Wittenberg is situated on the River Elbe, north of Leipzig and south-west of Berlin, and has a population of 46,008 (2018). Wittenberg is famous for its close connection with Martin Luther and the Protestant Reformation, for which it received the honourific ''Lutherstadt''. Several of Wittenberg's buildings are associated with the events, including a preserved part of the Augustinians, Augustinian monastery in which Luther lived, first as a monk and later as owner with his wife Katharina von Bora and family, considered to be the world's premier museum dedicated to Luther. Wittenberg was also the seat of the Elector of Saxony, a dignity held by the dukes of Duchy of Saxe-Wittenberg, Saxe-Wittenberg, making it one of the most powerful cities in the Holy Roman Empire.

Magnetism
Magnetism is the class of physical attributes that are mediated by a magnetic field, which refers to the capacity to induce attractive and repulsive phenomena in other entities. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomena of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets, producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron, cobalt, and nickel and their alloys. The rare-earth metals neodymium and samarium are less common examples. The prefix ' refers to iron because permanent magnetism was first observed in lodestone, a form of natural iron ore called magnetite, Fe3O4. All substances exhibit some type of ...

Carl Friedrich Gauss
Johann Carl Friedrich Gauss (; german: Gauß ; la, Carolus Fridericus Gauss; 30 April 177723 February 1855) was a German mathematician and physicist who made significant contributions to many fields in mathematics and science. Sometimes referred to as the ''Princeps mathematicorum'' () and "the greatest mathematician since antiquity", Gauss had an exceptional influence in many fields of mathematics and science, and he is ranked among history's most influential mathematicians. Also available at Retrieved 23 February 2014. Comprehensive biographical article. Biography Early years Johann Carl Friedrich Gauss was born on 30 April 1777 in Brunswick (Braunschweig), in the Duchy of Brunswick-Wolfenbüttel (now part of Lower Saxony, Germany), to poor, working-class parents. His mother was illiterate and never recorded the date of his birth, remembering only that he had been born on a Wednesday, eight days before the Feast of the Ascension (which occurs 39 days after Easter).

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Memorial To Wilhelm Weber, Wittenberg Post Office
A memorial is an object or place which serves as a focus for the memory or the commemoration of something, usually an influential, deceased person or a historical, tragic event. Popular forms of memorials include landmark objects or works of art such as sculptures, statues or fountains and parks. Larger memorials may be known as monuments. Types The most common type of memorial is the gravestone or the memorial plaque. Also common are war memorials commemorating those who have died in wars. Memorials in the form of a cross are called intending crosses. Online memorials are often created on websites and social media to allow digital access as an alternative to physical memorials which may not be feasible or easily accessible. When somebody has died, the family may request that a memorial gift (usually money) be given to a designated charity, or that a tree be planted in memory of the person. Those temporary or makeshift memorials are also called grassroots memo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eduard Weber
Eduard Friedrich Weber (6 March 1806 – 18 May 1871) was a German anatomist and physiologist. He was a younger brother to physiologist Ernst Heinrich Weber (1795-1878) and physicist Wilhelm Eduard Weber (1804-1891). Weber was born in Wittenberg. He studied medicine at the University of Halle, receiving his doctorate in 1829. From 1836 he served as prosector in the anatomical institute at the University of Leipzig, where in 1838 he became privat-docent with a thesis involving physiological studies on the " galvano-magnetic phenomena" in humans. From 1847 to 1871 he was an associate professor at Leipzig. He assisted his older brother, Ernst, with experimentation involving the inhibitory power of the vagus nerve.

Ernst Heinrich Weber
Ernst Heinrich Weber (24 June 1795 – 26 January 1878) was a German physician who is considered one of the founders of experimental psychology. He was an influential and important figure in the areas of physiology and psychology during his lifetime and beyond. His studies on sensation and touch, along with his emphasis on good experimental techniques led to new directions and areas of study for future psychologists, physiologists, and anatomists. Ernst Weber was born into an academic background, with his father serving as a professor at the University of Wittenberg. Weber became a doctor, specializing in anatomy and physiology. Two of his younger brothers, Wilhelm and Eduard, were also influential in academia, both as scientists with one specializing in physics and the other in anatomy. Ernst became a lecturer and a professor at the University of Leipzig and stayed there until his retirement. Early life Ernst Heinrich Weber was born on 24 June 1795 in Wittenberg, Saxony, Holy ...

Magnetic Flux
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted or . The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics, that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux. Description The magnetic interaction is described in terms of a vector field, where each point in space is associated with a vector that determines what force a moving charge would experience at that point (see Lorentz force). Since a vector field is quite difficult to visualize at first, in elementary physics one may instead visualize this field with field lines. The magnetic flux through some surface, in this simplified picture, is proportional to the num ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
