He is remembered today largely for his work on gravitation and surface tension, and the invention of the torsion pendulum. In addition to Eötvös Loránd University and the Eötvös Loránd Institute of Geophysics in Hungary, the Eötvös crater on the Moon, the asteroid 12301 Eötvös and the mineral lorándite also bear his name, as well as peak (Cime Eotvos) in the Dolomites. Life Born in 1848, the year of the Hungarian revolution, Eötvös was the son of the Baron József Eötvös de Vásárosnamény (1813–1871), a well-known poet, writer, and liberal politician, who was cabinet minister at the time, and played an important part in 19th century Hungarian intellectual and political life. His mother was the Hungarian noble lad ...

Torsion Pendulum
A torsion spring is a spring that works by twisting its end along its axis; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted. There are various types: *A torsion bar is a straight bar of metal or rubber that is subjected to twisting (shear stress) about its axis by torque applied at its ends. *A more delicate form used in sensitive instruments, called a torsion fiber consists of a fiber of silk, glass, or quartz under tension, that is twisted about its axis. *A helical torsion spring, is a metal rod or wire in the shape of a helix (coil) that is subjected to twisting about the axis of the coil by sideways forces (bending moments) applied to its ends, twisting the coil tighter. *Clocks use a spiral wound torsion spring (a form of helical torsion spring where the coils are around each other instead of piled up) sometimes cal ...

Exploration
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Human, Homo sapiens'' history, saw humans Recent African origin of modern humans, moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Settlement of the Americas, Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B ...

Hungarian Nobility
The Hungarian nobility consisted of a privileged group of individuals, most of whom owned landed property, in the Kingdom of Hungary. Initially, a diverse body of people were described as noblemen, but from the late 12th century only high-ranking royal officials were regarded as noble. Most aristocrats claimed ancestry from a late 9th century Magyar leader. Others were descended from foreign knights, and local Slavic chiefs were also integrated in the nobility. Less illustrious individuals, known as castle warriors, also held landed property and served in the royal army. From the 1170s, most privileged laymen called themselves royal servants to emphasize their direct connection to the monarchs. The Golden Bull of 1222 enacted their liberties, especially their tax-exemption and the limitation of their military obligations. From the 1220s, royal servants were associated with the nobility and the highest-ranking officials were known as barons of the realm. Only those who ...

Hungarian Revolution Of 1848
The Hungarian Revolution of 1848 or fully Hungarian Civic Revolution and War of Independence of 1848–1849 () was one of many European Revolutions of 1848 and was closely linked to other revolutions of 1848 in the Habsburg areas. Although the revolution failed, it is one of the most significant events in Hungary's modern history, forming the cornerstone of modern Hungarian national identity. In April 1848, Hungary became the third country of Continental Europe (after France (1791), and Belgium (1831)) to enact law about democratic parliamentary elections. The new suffrage law (Act V of 1848) transformed the old feudal parliament ( Estates General) into a democratic representative parliament. This law offered the widest suffrage right in Europe at the time. The crucial turning point of events was when the new young Austrian monarch Franz Joseph I arbitrarily revoked the April laws (ratified by King Ferdinand I) without any legal competence. This unconstitutional act irrever ...

Dolomites
The Dolomites ( it, Dolomiti ; Ladin: ''Dolomites''; german: Dolomiten ; vec, Dołomiti : fur, Dolomitis), also known as the Dolomite Mountains, Dolomite Alps or Dolomitic Alps, are a mountain range located in northeastern Italy. They form part of the Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley (Pieve di Cadore) in the east. The northern and southern borders are defined by the Puster Valley and the Sugana Valley (Italian: ''Valsugana''). The Dolomites are located in the regions of Veneto, Trentino-Alto Adige/Südtirol and Friuli Venezia Giulia, covering an area shared between the provinces of Belluno, Vicenza, Verona, Trentino, South Tyrol, Udine and Pordenone. Other mountain groups of similar geological structure are spread along the River Piave to the east – ''Dolomiti d'Oltrepiave''; and far away over the Adige River to the west – ''Dolomiti di Brenta'' (Western Dolomites). A smaller group is called ''Piccole Dolomiti'' (Li ...

Lorándite
Lorándite is a thallium arsenic sulfosalt with the chemical formula: TlAsS2. Though rare, it is the most common thallium-bearing mineral. Lorandite occurs in low-temperature hydrothermal associations and in gold and mercury ore deposits. Associated minerals include stibnite, realgar, orpiment, cinnabar, vrbaite, greigite, marcasite, pyrite, tetrahedrite, antimonian sphalerite, arsenic and barite. The mineral is being used for detection of solar neutrino via a certain nuclear reaction involving thallium. It has a monoclinic crystal structure consisting of spiral chains of AsS3 tetrahedra interconnected by thallium atoms, and can be synthesized in the laboratory. History Lorándite was first discovered at the Allchar deposit, near Kavadarci (now North Macedonia) in 1894 and named after Loránd Eötvös, a prominent Hungarian physicist. Distribution Apart from the Allchar deposit in North Macedonia, lorandite is also found at the Dzhizhikrut Sb–Hg deposit in Tajikistan and at th ...
