Roanne
Roanne (; frp, Rouana; oc, Roana) is a commune in the Loire department, central France. It is located northwest of Lyon on the river Loire. It has an important Museum, the ''Musée des Beaux-arts et d'Archéologie Joseph-Déchelette'' (French), with many Egyptian artifacts. Economy Roanne is known for gastronomy (largely because of the famous Troisgros family), textiles, agriculture and manufacturing tanks. Roanne station has rail connections to Clermont-Ferrand, Saint-Étienne, Moulins and Lyon. History The toponymy is Gaulish, ''Rod-Onna'' ("flowing water") which became ''Rodumna'', then ''Rouhanne'' and ''Roanne''. The town was sited at a strategic point, the head of navigation on the Loire, below its narrow gorges. As a trans-shipping point, its importance declined with the collapse of long-distance trade after the fourth century. In the twelfth century, the site passed to the comte du Forez, under whose care it began to recover. An overland route led to Lyon and the ...

UA1 Experiment
The UA1 experiment (an abbreviation of Underground Area 1) was a high-energy physics experiment that ran at CERN's Proton-Antiproton Collider (SpS), a modification of the one-beam Super Proton Synchrotron (SPS). The data was recorded between 1981 and 1990. The joint discovery of the W and Z bosons by this experiment and the UA2 experiment in 1983 led to the Nobel Prize for physics being awarded to Carlo Rubbia and Simon van der Meer in 1984. Peter Kalmus and John Dowell, from the UK groups working on the project, were jointly awarded the 1988 Rutherford Medal and Prize from the Institute of Physics for their outstanding roles in the discovery of the W and Z particles. It was named as the first experiment in a CERN "Underground Area" (UA), i.e. located underground, outside of the two main CERN sites, at an interaction point on the SPS accelerator, which had been modified to operate as a collider. The UA1 central detector was crucial to understanding the complex topology of pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Organization For Nuclear Research
The European Organization for Nuclear Research, known as CERN (; ; ), is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in a northwestern suburb of Geneva, on the France–Switzerland border. It comprises 23 member states, and Israel (admitted in 2013) is currently the only non-European country holding full membership. CERN is an official United Nations General Assembly observer.

Kennedy J
Anthony McLeod Kennedy (born July 23, 1936) is an American lawyer and jurist who served as an associate justice of the Supreme Court of the United States from 1988 until his retirement in 2018. He was nominated to the court in 1987 by President Ronald Reagan, and sworn in on February 18, 1988. After the retirement of Sandra Day O'Connor in 2006, he was the swing vote on many of the Roberts Court's 5–4 decisions. Born in Sacramento, California, Kennedy took over his father's legal practice in Sacramento after graduating from Harvard Law School. In 1975, President Gerald Ford appointed Kennedy to the United States Court of Appeals for the Ninth Circuit. In November 1987, after two failed attempts at nominating a successor to Associate Justice Lewis F. Powell Jr., President Reagan nominated Kennedy to the Supreme Court. Kennedy won unanimous confirmation from the United States Senate in February 1988. Following the death of Antonin Scalia in February 2016, Kennedy became the s ...

Large Hadron Collider
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories, as well as more than 100 countries. It lies in a tunnel in circumference and as deep as beneath the France–Switzerland border near Geneva. The first collisions were achieved in 2010 at an energy of 3.5 teraelectronvolts (TeV) per beam, about four times the previous world record. After upgrades it reached 6.5 TeV per beam (13 TeV total collision energy). At the end of 2018, it was shut down for three years for further upgrades. The collider has four crossing points where the accelerated particles collide. Seven detectors, each designed to detect different phenomena, are positioned around the crossing points. The LHC primarily collides proton beams, but it can also accelerate beams of heavy ion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stellar Evolution
Stellar evolution is the process by which a star changes over the course of time. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the age of the universe. The table shows the lifetimes of stars as a function of their masses. All stars are formed from collapsing clouds of gas and dust, often called nebulae or molecular clouds. Over the course of millions of years, these protostars settle down into a state of equilibrium, becoming what is known as a main-sequence star. Nuclear fusion powers a star for most of its existence. Initially the energy is generated by the fusion of hydrogen atoms at the core of the main-sequence star. Later, as the preponderance of atoms at the core becomes helium, stars like the Sun begin to fuse hydrogen along a spherical shell surrounding the core. This process causes the star to gradually grow in size, passing throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellar Equilibrium
Stellar structure models describe the internal structure of a star in detail and make predictions about the luminosity, the stellar classification, color and the stellar evolution, future evolution of the star. Different classes and ages of stars have different internal structures, reflecting their element (chemistry), elemental makeup and energy transport mechanisms. Energy transport Different layers of the stars transport heat up and outwards in different ways, primarily convection and radiative transfer, but heat conduction, thermal conduction is important in white dwarfs. Convection is the dominant mode of energy transport when the temperature gradient is steep enough so that a given parcel of gas within the star will continue to rise if it rises slightly via an adiabatic process. In this case, the rising parcel is buoyant and continues to rise if it is warmer than the surrounding gas; if the rising parcel is cooler than the surrounding gas, it will fall back to its origina ...
